Answer:

Duration = 6 hours

Step-by-step explanation:

Given

[tex]Regina: 6.50h + 16[/tex]

[tex]Phil: 3(2.5h + 5)[/tex]

[tex]Joseph: 7.50h + 10[/tex]

Required

When will Ragina and Joseph earn equal amounts

To solve this:

[tex]Regina = Joseph[/tex] must be true

This gives:

[tex]6.50h + 16 = 7.50h + 10[/tex]

Collect Like Terms

[tex]7.50h - 6.50h = 16 - 10[/tex]

[tex]h = 6[/tex]

Hence, number of hours is 6

Hey there! I'm happy to help!

We have 8 bags of dog food and each costs $25.19

8(25.19)=201.52

And we have 11 leashes each costing $4.65.

11(4.65)=51.15

We add these totals up.

201.52+51.15=252.67

We subtract this from 300 to see how much is left.

300-252.67=47.33

Rhonda had $47.33 left after her purchases.

Have a wonderful day! :D

Answer:

$47.33

Step-by-step explanation:

she bought 8 bags of dog food so: 8 x 25.19 = 201.52

she bought 11 leashes so: 4.65 x 11 = 51.15

201.52 + 51.15 = 252.67

300 - 252.67 = 47.33

Answer:

The graph is misleading because the vertical scale is not even. It goes from 0 to 15 and then thereafter the scale reverts to a scale of 5.

This is misleading because had the graph gone in a scale of 5 from the get go, the number of people who thought 3-4 episodes were too much would have looked higher in the graph as they seem to comprise of about 5% of the sample population.  

The scale should begin at 0 and then go like 5 ⇒ 10 ⇒ 15 ⇒ 20 ⇒ 25 ⇒ 30

Answer:

The mode of the data for Store 2 is greater than the mode of the data for Store 1.

Step-by-step explanation:

The mode of store 2 greater than mode of store 1.

A box plot, commonly referred to as a box and whisker plot, is a form of chart that is frequently used in explanatory data analysis in descriptive statistics. Box plots use the data's quartiles (or percentiles) and averages to visually depict the distribution of numerical data and skewness.

Given:

Dot plots show the numbers of children’s books purchased by customers at two different bookstores.

Now, from the given figure

The mode of store 1 is 3

and, mode of store 2 is 4.

Hence, the mode of store 2 greater than mode of store 1.

Answer:

5/6

Step-by-step explanation:

y+4-y+1=6y

5=6y

y=5/6

Solution for (y+4)-(y-1)=6y equation:

Simplifying

(y + 4) + -1(y + -1) = 6y

Reorder the terms:

(4 + y) + -1(y + -1) = 6y

Remove parenthesis around (4 + y)

4 + y + -1(y + -1) = 6y

Reorder the terms:

4 + y + -1(-1 + y) = 6y

4 + y + (-1 * -1 + y * -1) = 6y

4 + y + (1 + -1y) = 6y

Reorder the terms:

4 + 1 + y + -1y = 6y

Combine like terms: 4 + 1 = 5

5 + y + -1y = 6y

Combine like terms: y + -1y = 0

5 + 0 = 6y

5 = 6y

Add '-6y' to each side of the equation.

5 + -6y = 6y + -6y

Combine like terms: 6y + -6y = 0

5 + -6y = 0

Add '-5' to each side of the equation.

5 + -5 + -6y = 0 + -5

Combine like terms: 5 + -5 = 0

0 + -6y = 0 + -5

-6y = 0 + -5

Combine like terms: 0 + -5 = -5

-6y = -5

Divide each side by '-6'.

y = 0.8333333333

Simplifying

y = 0.8333333333

Step-by-step explanation:

You set this up with a ratio,  1:20 or 1 equals 20 miles.   So i'm multiplying by 20 regardless.   Now I have 2 and a half inches or you can say 2.5.  Multiply 2.5 (on paper..) and 20 and there you go.    20 times 2 equals 40 and 20 times a half is 10, 40 + 10= 50.  

Answer:

x = 6

Step-by-step explanation:

Since <A is congruent to <N, they are both an isosceles base angles. ∆CAN is an isosceles ∆.

Therefore, one of the properties of an isosceles ∆ is that two sides are equal, aside the base of the isosceles. This implies that: CN = AC

AC = 18cm

CN = (4x - 6)cm, therefore, we can generate an equation for solve for x as follows,

4x - 6 = 18 (two sides of an isosceles ∆ are congruent)

Add 6 to each side of the equation.

4x - 6 + 6 = 18 + 6

4x = 24

Divide both sides by 4

4x = 24/4

x = 6

Answer:

B 32

Step-by-step explanation:

30 oranges would be required to maintain the same ratio with 20 apples.

In the example fruit basket, there are 2 apples for every 3 oranges, based on the provided ratio.

We must establish a proportion in order to determine how many oranges are required to keep the same ratio with 20 apples.

Let "x" stand for the required quantity of oranges.

The ratio can be configured as follows:

20 apples/x oranges = 2 apples/3 oranges.

Cross-multiplication allows us to find the value of "x":

3(20) = 2x

2x = 60

x = 30

As a result, 30 oranges would be required to maintain the same ratio with 20 apples.

Step-by-step explanation:

Answer in image below press on it

Given :

The weight of an object on a particular scale is 125.2 lbs.

The actual weight by at most 0.4 lbs.

To Find :

The range of actual  weights of the object.

Solution :

It is given that uncertainty in weight is 0.4 lbs.

So, minimum weight can be( 125.2 -0.4 ) = 124.8 lbs.

Maximum weight is given by  ( 125.2 + 0.4 ) = 125.6 lbs.

Therefore, the range of actual  weights of the object is between :

124.8  x 125.6 .

Hence, this is the required solution.

Answer:

It looks like this question is not solvable. So, if this is absolutely correct, write "no solution".

Step-by-step explanation:

Below is the first step to attempt solving the equation.

The little twos at the top of each number are called exponents. This means a number times itself.

So,

537*537=288,369

15.9*15.9=252.81

74*74=5476

Now, take the 288,369*252.81 to get a total of 72,902,566.89 .

Since this answer is (obviously) not equal to the 5476 on the other side, the two are not equal.

Here's how you'd work it out on paper to show it isn't solvable.

(537*537)*(15.9*15.9)= (74*74)

(288,369)*(252.81)= 5476

72,902,566.89 ≠5476

So the answer would be:

Not solvable.

Answer:

[tex]x=\sqrt{3}-2\\x=-\sqrt{3}-2\\x=\frac{1}{2}[/tex]

Step-by-step explanation:

This is a hard one

We have to use the rational root theorem

[tex]2x^3+7x^2-2x-1[/tex] = 0

We have to find all the factors of a and d and put them in a fraction

[tex]a=2\\d=-1\\\frac{1}{1,2}[/tex]

We then plug them into the equation to see if any of them work

The equation isn't true when plugging 1, but is true when plugging in 1/2

factored form of 1/2 is (2x-1)

Then we divide the original equation by (2x-1) (you can use synthetic division or long division, it would be hard to type out the process for that) to get [tex]x^2+4x+1[/tex]

So now the equation is [tex](2x-1)(x^2+4x+1)[/tex]

Solve the second half of this equation using the quadratic formula to get

[tex]\sqrt{3}-2[/tex] and [tex]-\sqrt{3}-2[/tex]

We already know the solution for the first half of the equation (1/2)

So the final answers are:

[tex]x=\sqrt{3}-2, -\sqrt{3}-2, \frac{1}{2}[/tex]

Answer:

write the right question first your question is wrong

Given :

P( X = 70 ) = 0.62 .

P( X = 80 ) = 0.23 .

To Find :

We need to find If a person reaches their 70th birthday, what is the probability that they will live to age 80 .

Solution :

We need to find :

[tex]P(X=70 | X=80 )[/tex]

We know ,

[tex]P(x,y ) = \dfrac{P(x)}{P(y)}[/tex]

So ,

[tex]P(X=70 | X=80 )=\dfrac{P(X=80)}{P(X=70)}\\\\=\dfrac{0.62}{0.23}=0.371[/tex]

Hence , this is the required solution .
