weight. Which of the following is not correct? (a) The slope is 3, which indicates that a mouse's weight should increase by about 3 grams for each additional millimeter of tail length. (b) The predicted tail length of a mouse that weighs 38 grams is 134 millimeters. (c) By looking at the equation of the least-squares line, you can see that the correlation between weight and tail length is positive. (d) If you had measured the tail length in centimeters instead of millimeters, the slope of the regression line would have been 3/10 = 0.3. (e) One mouse weighed 29 grams and had a tail length of 100 millimeters. The residual for this mouse is -7.

Answers

Answer 1

The part (a) is not correct i.e. The slope is 3, which indicates that a mouse's weight should increase by about 3 grams for each additional millimeter of tail length.

What is Regression analysis ?

Regression analysis is the process of determining how one or more variables and the outcome variable relate to one another. Risk factors, co-founders, and the outcome variable are all referred to as predictors or independent variables. The result variable is sometimes referred to as the dependent or response variable. Regression analysis displays the dependent variable as "y" and the independent variables as "x".

Given, tail length = (3 × weight) + 20

(a) Here, The slope is 3 which indicates that a mouse's length is the sum of 3 times the weight and 20. So, the statement is not correct.

(b) If weight is 38 gm, then

    tail length = 38 × 3 + 20

                     = 114 + 20 = 134mm.

So, the statement is correct.

(c) We've  tail length = (3 × weight) + 20

we can see that the relationship between the two is positive because when the weight is increased, the tail length also increases.

So, the given statement is correct.

(d) The slope is 3 when the tail length is being measured in millimeters.

Now, If we measure it in centimeter = 3/10 = 0.3 cm

∵ 1 mm = 1/10 cm.

So, the given statement is correct.

(e) when a mouse has weight of 29 grams and tail length of 100 mm.

    When the weight is 29 grams, it should have tail length as :

             tail length = 29 × 3 + 20

                              = 107 mm.

  but, tail length is given as 100 mm.

So, the residual for the mouse is -7 i.e. (100 - 107)

Hence, The given statement is correct.

(a) 794g of the initial sample will be left in the sample after 25 years. (b) Time taken to decay to half of its original amount is 3.39 years.

Isotopes(200g) are atoms that have the same number of protons in their nucleus, but a different number of neutrons. This means that they have the same atomic number, but a different atomic mass. Because of this, isotopes have different physical and chemical properties. Isotopes can be stable, meaning that they do not undergo radioactive decay, or they can be unstable, meaning that they will undergo radioactive decay over time.

(a) Substituting 25 for t in the expression, we get:

[tex]A(25) = 200e^{0.0541 \times 25}[/tex]

         [tex]= 200e^{1.3525}[/tex]

Thus, after 25 years, there will be

[tex]200e^{1.3525} = 2003.97[/tex]

794 g of the initial sample left in the sample.

(b) We want to find t such that

[tex]A(t) = 200e^{0.0541}[/tex]

Solving for t, we get:

Given a function value of an acute angle, find the other five trigonometric function values

Answers

The other five trigonometric function values are cos(∅) = 11/61, tan(∅) = 60/11, sec(∅) = 61/11, csc(∅) = 61/60 and cot(∅) = 11/60

How to determine the other five trigonometric function values

From the question, we have the following parameters that can be used in our computation:

sin(∅) = 60/61

The cosine of the angle can be calculated using

sin²(∅) + cos²(∅) = 1

Substitute the known values in the above equation, so, we have the following representation

(60/61)² + cos²(∅) = 1

This gives

cos²(∅) = 1 - (60/61)²

Evaluate the like terms

cos²(∅) = 121/3721

Take the square root of both sides

cos(∅) = 11/61

The tangent of the angle can be calculated using

tan(∅) = sin(∅)/cos(∅)

Substitute the known values in the above equation, so, we have the following representation

tan(∅) = (60/61)/(11/61)

Evaluate

tan(∅) = 60/11

The other ratios of the angle are calculated as follows

sec(∅) = 1/cos(∅) = 61/11

csc(∅) = 1/sin(∅) = 61/60

cot(∅) = 1/tan(∅) = 11/60

Answers

To estimate the population proportion to within plus or minus 2% with 95% confidence, a sample size of at least 804 is needed.

How do we get the sample size for estimating a population proportion?

This can be calculated using the formula for determining sample size for estimating a population proportion:

n = (Z^2 * p * (1-p)) / (E^2)

Where n is the sample size, Z is the z-score corresponding to the desired level of confidence (1.96 for 95% confidence), p is the estimated proportion of the population with the characteristic of interest (assumed to be 0.5 for this calculation), and E is the maximum margin of error desired (2% in this case). Plugging these values into the formula, we get:

n = (1.96^2 * 0.5 * (1-0.5)) / (0.02^2) = 803.84

Since this is a sample size estimate, we should round up to the next whole number, resulting in a sample size of 804.

Let’s call the hypotenuse of each right triangle ‘a’, the base ‘b’ and the height ‘c’

Pythagorean theorem = a^2 + b^2 = c^2

We need to find the height ‘c’ so:

a = 10 cm
b = 5 cm
c = ?

10^2 + 5^2 = c^2

100 + 25 = c^2

125 = c^2

c = square root of 125

c = 11.18 cm

So the height of the total equilateral triangle is 11.18 cm.

Answers

There are 407.83 square feet living room.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The carpet cost $4.15 per square foot and $97 to have it stalled.

And, Their total bill is $1, 789.50.

Now,

Let number of square feet living room = x

So, We can formulate;

⇒ 4.15x + 97 = 1,789.50

Solve for x as;

⇒ 4.15x = 1,789.50 - 97

⇒ 4.15x = 1,692.5

⇒ x = 1,692.5 / 4.15

⇒ x = 407.83 square feet

Thus, There are 407.83 square feet living room.

Answers

The equation of the line in slope intercept form that passes through the point (3,4) and is parallel to the line represented by y=3x−2 is y = 3x - 5.  

How to find equation of a line?

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

m = slopeb = y-intercept

Therefore, the line that passes through the point (3,4) and is parallel to the line represented by y = 3x − 2.

Parallel line have the same slope. Therefore, the slope of the line is 3.

Let's find the y-intercept using (3, 4).

y = 3x + b

4 = 3(3) + b

4 - 9 = b

b = -5

What is a parallelogram?

A parallelogram is a straightforward quadrilateral with two sets of parallel sides in Euclidean geometry.

A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

So, extend segments JM and JK beyond points M and J, respectively, and draw points P and Q.

It is assumed that a parallelogram with segments JM parallel to segments KL and JK parallel to segments ML is presented.

Draw point P and extend segment JM past point M through construction.

Through construction also Continue segment JK draws point Q after point J. 

Consequently, the Alternate Interior Angles Theorem ∠MLK≅∠PML and ∠JML≅∠QJM (1)

Then, the corresponding angles theorem ∠PML≅∠KJM and ∠QJM≅∠LKJ is applied (2)

Equations (1) and (2) and the transitive property of equality are used to create:

∠MLK≅∠KJM and ∠JML≅∠LKJ

As a result, the supplied parallelogram JKLM's opposite angles are congruent. So it was proved.

Answers

The other five function values are sin(Ф)= -4/5, tan(Ф)= 4/3, cot(Ф)= 3/4, sec(Ф)= -5/3 and csc(Ф)= -5/4.

what is trigonometry?Trigonometry is a field of mathematics that examines correlations between triangle side lengths and angles (from the Ancient Greek words "trigonon" and "metron"). The field was created in the Hellenistic era in the third century BC as a result of the use of geometry in astronomical research. Trigonometry has a wide variety of identities. With the intention of simplifying an expression, finding a more practical form of an expression, or solving an equation, these trigonometric identities are frequently employed to rewrite trigonometrical expressions.

Since x is in IIIrd quadrant sin and cos will be negative but tan will be positive

given cos x= -3/5

We know that

sin²x + cos²x=1

sin²x+(-3/5)²=1

sin²x+9/25=1

sin²x=1-9/25

sin²x=16/25

sinx= ±√16/25

sinx= ±4/5

since, x is in IIIrd quadrant.

As sinx is negative IIIrd quadrant,

∴sinx= -4/5

tanx=sinx/cosx

      =-4/5÷-3/5

      =4/3

cotx=1/tanx

      =1/4/3

      =3/4

cosecx=1/sinx

           =1/-4/5

           =-5/4

secx=1/cosx

       =1/-3/5

       =-5/3

Hence, The other five function values are sin(Ф)= -4/5, tan(Ф)= 4/3, cot(Ф)= 3/4, sec(Ф)= -5/3 and csc(Ф)= -5/4.

The perimeter of the triangle BAG is 43. AG= 16, AB=x+4, and BG= 2x+2. What is the value of x?

Answers

Answer:

x=7

isosceles triangle

Step-by-step explanation:

To find the perimeter we just add all the sides so we do that for this too

(X+4)+(2x+2)+(16)

And we set it equal to 43 since that is perimeter

(X+4)+(2x+2)+(16)=43

Combine like terms

3x+22=43

   -22.  -22

3x=21

/3.  /3

x=7

And if we fill in the x we find BG and AG are equal so this is an Isosceles triangle

Hopes this helps

Answer:

x = 7

Isosceles triangle

Step-by-step explanation:

The perimeter of a two-dimensional shape is the distance all the way around the outside.

Given values of triangle BAG:

Perimeter = 43AG = 16AB = x + 4BG = 2x + 2

Therefore:

⇒ AG + AB + BG = perimeter

⇒ 16 + x + 4 + 2x + 2 = 43

⇒ x + 2x + 16 + 4 + 2 = 43

⇒ 3x + 22 = 43

⇒ 3x + 22 - 22 = 43 - 22

⇒ 3x = 21

⇒ 3x ÷ 3 = 21 ÷ 3

⇒ x = 7

Substitute the found value of x into the expressions for AB and BG to find their lengths:

⇒ AB = x + 4

⇒ AB = 7 + 4

⇒ AB = 11

⇒ BG = 2x + 2

⇒ BG = 2(7) + 2

⇒ BG = 14 + 2

⇒ BG = 16

As sides BG and AG are both 16 units in length, the triangle is an isosceles triangle (as it has two sides of equal length).

1. In 60 weeks, both Zac and Jon will earn the same amount, equating to their different earnings.

2. The student's claim that the solution to the equation 200 + 20w = -100 + 25w is w = 50 is false as the solution shows that w = 60.

3. The two correct justifications for the given steps used in solving w are:

Step 1: Combining like termsStep 3: Division Property of Equality.

How the equations are determined?

The fixed earnings of Zac = $200

Zac's earnings per week = $20

The total earnings of Zac in w weeks = 200 + 20w

Jon's fixed debt so far = $100

Jon's earnings per week = $25

The total earnings of Jon in w weeks = -100 + 25w

To determine the weeks when the total earnings of Zac and Jon will be equal, we can equate the two expressions above as follows and solve for w:

200 + 20w = -100 + 25w

20w - 25w = -300

-5w = - 300

w = -300/-5

w = 60

Thus, we can conclude that in 60 weeks, the earnings of Zac and Jon will become equal.
