Answers

The value of y is less than or equal to 0 (y ≤ 0).

What is inequality?

In mathematics, inequalities describe the relationship between two values that are not equal. Equal means to be equal, not. The "not equal symbol ()" is typically used to indicate that two values are not equal. But different inequalities are used to compare the values to determine whether they are less than or greater than.

Given:

4y + 1/5 ≤ 4/5

We have to find the value of y.

Subtract 1/5 from both sides,

4y + 1/5 - 1/5 ≤ 4/5 - 1/5

              4y ≤ 3/5

Multiply both sides by 1/4

4y x 1/4 ≤ 3/5 x 1/4

y ≤ 3/20

y ≤ 0.15

Hence, the value of y is less than or equal to 0 (y ≤ 0).

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 70 pounds. The truck is transporting 65 large boxes and 50 small boxes. If the truck is carrying a total of 4250 pounds in boxes, how much does each type of box weigh?
Large box: ___ Pounds
Small box: ___Pounds

Answers

The weight of large box will be 45 pounds.

The weight of small box will be 30 pounds.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The combined weight of a large box and a small box is 75 pounds.

And, The truck is transporting 55 large boxes and 70 small boxes.

Total weight of boxes = 4575 pounds

Now,

Let weight of large box = x

And, Weight of small box = y

Here, The combined weight of a large box and a small box is 75 pounds.

So, We can formulate;

⇒ x + y = 75   ...(i)

And, Total weight of boxes = 4575 pounds

So, We can formulate;

⇒ 55x + 70y = 4575   ...(ii)

Solve both equation as;

From (i);

x = 75 - y

Substitute in equation (ii), we get;

⇒ 55(75 - y) + 70y = 4575

⇒ 4,125 - 55y + 70y = 4575

⇒ 15y = 4575 - 4,125

⇒ 15y = 450

⇒ y = 30

And, x = 75 - 30 = 45

Thus, The weight of large box will be 45 pounds.

The weight of small box will be 30 pounds.

The estimated average annual growth rate of the​ country's population for 1950 is enter your response here ___________

Answers

The average annual growth rate of a certain country's population for 1950, 1988, and 2010 are 1.819, -0.1300048 and -1.4474respectively.

What is an equation?

Equation: An algebraic expression composed of two expressions with the same value and the symbol "=" in between.

The given equation is

y = -0.0000084x³ + 0.00194x² -0.196x + 7.819

Where Y is the annual growth rate of  a certain country's population and x is the number of years after 1900.

Difference between 1950 and 1900 is 50.

Put x=50 in the given equation.

y = -0.0000084(50)³ + 0.00194(50)² -0.196(50) + 7.819

y = 1.819

Therefore, the estimated average annual growth rate of the country's population for 1950 is 1.819.

The difference between 1988 and 1900 is 88.

Put x=88 in the given equation.

y = -0.0000084(88)³ + 0.00194(88)² -0.196(88) + 7.819

y= -0.1300048

Therefore, the estimated average annual growth rate of the country's population for 1988 is 0.9985.

Difference between 2010 and 1900 is 110.

Put x=110 in the given equation.

y = -0.0000084(110)³ + 0.00194(110)² -0.196(110) + 7.819

y= -1.4474

Therefore, the estimated average annual growth rate of the country's population for 2010 is 0.2236.

Therefore, population growth rates for a particular nation in 1950, 1988, and 2010 are, respectively, 1.819, -0.1300048 and -1.4474.

Write an equation of the line that passes through (-1, 3) and is parallel to the line y = -3x + 2

Answers

Answer:

  y -3 = -3(x +1)

Step-by-step explanation:

You want an equation for the line parallel to y=-3x+2 through the point (-1, 3).

Slope-intercept form

The given line is written in slope-intercept form:

  y = mx +b . . . . . . . where m is the slope and b is the y-intercept

Matching your equation to this form, we see that ...

m = -3b = 2

The parallel line will have the same slope: m = -3.

width:
9-A 17 1/2"
9-B 8"
9-C
11"
9-D 14 1/2"

Answers

Answer:

Length = 11"  and  width = 8".

Step-by-step explanation:

let L be the length of the rectangle

and w be its width.

Formula (perimeter P of a rectangle) :

P = 2 × (L + w)

================================

Then

L = w + 3

and

P = 2 × (L + w)

  = 2 × (w + 3 + w)

  = 2 × (2w + 3)

  = 4w + 6

Solving the equation P = 4w + 6  for w :

P = 4w + 6

38 = 4w + 6

32 = 4w

w = 32 ÷ 4

   = 8

Determining the length L :

L = w + 3

L = 8 ÷ 3

  = 11

Conclusion:

L = 11  and  w = 8

Answer:

Width = 8"

Step-by-step explanation:

2(t+w) = 38              Eq. 1

t = w+3                     Eq. 2

t = length

w = width

From Eq. 2:

t+w = 38/2

t+w = 19

t = 19 - w                    Eq. 3

Replacing Eq. 3 in Eq. 2:

19 - w = w + 3

19 - 3 = w + w

16 = 2w

16/2 = w

w = 8

Frm Eq. 2:

t = w + 3

t = 8 + 3

t = 11

Check:

From Eq. 1

2(t+w) = 38

2(11+8) = 38

2(19) = 38

In a chi-square test for homogeneity of proportions,we test whether different populations have the same proportion of individuals with some characteristic.

What is chi-square test for proportions?

Used to test whether different populations have the same proportion of individuals with a particular trait. Suppose we have three populations with four mutually exclusive characteristics. Randomly sample each population and create a crosstabulation or frequency table of the traits you are measuring. If you want to test whether there is an association between a population and a trait (for example, whether the population has a high frequency of one trait), perform a chi-square test to see if the result is significant must be confirmed.

If the chi-square test is significant, it only tells us that there is some relationship between the population and the trait, not how they are related. Also, not all traits need to be population related. For example, the chi-square test can be considered significant even if features A and B have very different distributions, and C and D have very different distributions, for different populations. If you want to measure whether a particular trait is influenced by the population, use an equal proportions test (I call it the z-test, or prop.test() in R) for exactly that trait. You can do. In other words, if the chi-square test reveals a significant relationship, it is appropriate to use prop.test() to more accurately determine the nature of the relationship between the two sets of categories.

What does math's intercept mean?

The x-intercept and y-intercept are the points where a centre line the x- and y-axes, respectively.

Briefing:

Given the following parameters

Fixed price = $50

The rate of change is $5 if streaming providers pay $ 5.00 per unit.

The necessary profit is provided as follows for the entire number of streams:

P(x) = 50 + 5x

The y-intercept is the location where x equals zero.

P(x) = 50 + 5x

P(0) = 50 + 5(0)

P(0) = 50

Thus, the function's y-intercept is (0, 50)

For the slope

mx = 5x

m = 5

Consequently, the function's slope is 5.

Equation of this line is P(x) = 50 + 5x

P(x) = 50 + 5x = 950000

5x = 950000 - 50

can you find the exact circumference of a circle when you multipy the diameter by 22/7? explain

Answers

When you multiply the diameter by 22/7,  you find the approximate not exact circumference of a circle.

What is the Circumference of a circle?

The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by it.

Pi ( written as the Geek letter π) is a universal constant found by dividing the circumference of a circle by its diameter. So if you measure the diameter of a circle you can calculate its circumference by multiplying by π.

Circumference = π * diameter.

It's value to the nearest hundredth is 3.14 but its actual value is a decimal number that goes on without bounds. That is in Maths it is irrational and can't be written accurately as a fraction.

For example:

What is the circumference of a circle that has a radius of 7cm?

Approximately 22 cm.

Exactly 7πcm

The ratio between the circumference of a circle and its diameter is π. We commonly write c=2π r, using the radius instead and doubling it.

One is 22/7, which is common in use and the other is 355113 ≈ 3.1415929,

which is less well-known but very accurate for the number of digits you have to remember.

In the given example, we are told that the diameter is 7 cm.

So using the common approximation π ≈ 22/7,

we find that the circumference is approximately:

(22/7)* 7 cm

= 22cm

Hence, when you multiply the diameter by 22/7,  you find the approximate not exact circumference of a circle.

To ride the Metro, riders must pay $0.50 per stop plus a $2.00 ticket fee. If a rider rides the Metro for 6 stops, how much would their total ride be?

Answers

The required cost for the ride in the Metro is obtained as $5.

How to calculate the total cost?

The total cost can be calculated by multiplying the cost for one unit to the number of units.The cost for one unit is also called as unit rate. This method is based on the unitary method which states that the value of n number of quantities is equal to the product of n and the value of one quantity.

The cost of the ticket is given as $2.

And, the cost per stop is $0.50.

Now, in order to find the total cost of riding for 6 stops take the sum of fixed cost of ticket and the total cost for 6 stops as follows,

The cost of ticket + The cost for 6 stops

= 2 + 6 × 0.50 = 5

Hence, the cost for the total ride of the rider is $5.

What is a right angle triangle?

A triangle is said to be right-angled if one of its internal angles is 90 degrees, or if any angle is a right angle.

To find the length in right angle triangle, use Pythagoreans theorem,

(hypotenuse)² = (base)² + (height)²

Given that,

The length of the ladder = 10 ft.

The distance of the house from the bottom of the ladder = 7 ft.

Let the length of the top of the ladder from ground is x ft.

To find the height of the ladder  from the ground,

Use Pythagoreans theorem,

(hypotenuse)² = (base)² + (height)²

(10)² = (7)² + (x)²

100 = 49 + x²

x² = 100 - 49

x² = 51

x = 7.1414

or x = 7.14 ft

The top of the ladder from the ground is 7.14 ft.

-3x-4y=-1 3x-y=-4 elimination

Answers

Answer:

(- 1, 1 )

Step-by-step explanation:

- 3x - 4y = - 1 → (1)

3x - y = - 4 → (2)

add (1) and (2) term by term to eliminate x

0 - 5y = - 5

- 5y = - 5 ( divide both sides by - 5 )

y = 1

substitute y = 1 into either of the 2 equations and solve for x

substituting into (2)

3x - 1 = - 4 ( add 1 to both sides )

3x = - 3 ( divide both sides by 3 )

x = - 1

solution is (- 1, 1 )

Triangle BCD with vertices B(2, -1), C(4, 1), and D(5,-2):
scale factor = 3, centered at the origin

Answers

Answer:

To find the coordinates of the vertices of triangle BCD after it is scaled by a factor of 3, centered at the origin, you would first need to find the coordinates of the vertices of the triangle when it is centered at the origin. This can be done by subtracting the coordinates of the original centroid, which is the point (3.33, -0.66) for triangle BCD, from the coordinates of each vertex. So the coordinates of vertex B would be (2 - 3.33, -1 + 0.66) = (-1.33, -0.34), the coordinates of vertex C would be (4 - 3.33, 1 - 0.66) = (0.67, 0.34), and the coordinates of vertex D would be (5 - 3.33, -2 + 0.66) = (1.67, -1.34).

To scale the triangle by a factor of 3, you would multiply the coordinates of each vertex by 3. So the coordinates of the scaled triangle would be (-3.99, -1.02) for vertex B, (2.01, 1.02) for vertex C, and (5.01, -4.02) for vertex D.

Therefore, the coordinates of the vertices of triangle BCD after it is scaled by a factor of 3, centered at the origin, would be (-3.99, -1.02), (2.01, 1.02), and (5.01, -4.02).

Amy can swim 6 laps in 9 minutes. Each lap is 50 meters.
"At that rate, how many minutes would it take Amy to swim 800 meters? Enter the answer in the box.
minutes

Answers

Answer:

I'm pretty sure the answer is 24.024

Step-by-step explanation:

300meters = 9 minutes

300+300=600

2/3 of 300=24minutes

800÷50=16

800÷33.3=24.024 minutes

Answer:

24 minutes

----------------------

Since Amy can swim 6 laps in 9 minutes, then it takes:

9/6 = 1.5 minutes to swim one lap.

Number of laps in 800 m:

800/50 = 16 laps

Time to swim 16 laps:

16*1.5 = 24 min

find the mean, variance, and standard deviation for the number of heads when 17 coins are tossed. round your answers to three decimal places.

Answers

Factorials and the binomial theorem are utilized in the binomial distribution, a discrete probability distribution. Checking the sample space is the first step in deciding whether or not to use a binomial distribution with a given data set.

The binomial distribution would apply if there were multiple trials of the same experiment and only two outcomes in the sample space.

S=T,H,THT,H,THH,HTH,HHT,HHH in this case.

∴ n(S)=8.

Thus, the probability of each and every outcome is 18.

When tossing three coins, let X be the number of heads.

There can be 0, 1, 2, or 3 heads.

Therefore, X's possible values are 0, 1, 2, and 3.

P(X=0) = P (no head) = P(T) = 18.

P(X=1) = P (getting a single head) = P(HorTHTorH) = 38.

P (X=P (getting 2 P (THH, HTH, HHT)=38.
