Answer:

Option B is correct.

Step-by-step explanation:

Recall that the domain is the set of (unique) inputs and the range is the set of outputs (which do not have to be unique).

The set of inputs of the given relation is {-1, 9, -10, 1}, and this set is also found in Option B.  The set out outputs is {7, 2, 6, -6|, which is in Option B.

Step-by-step explanation:

The question is incomplete, as the required lengths are not given.

I will use the following data set to answer the question.

[tex]Dataset: 35, 51, 39, 42, 68, 62, 32, 59[/tex]

First, is to determine the range of the dataset

[tex]Range = Highest - Least[/tex]

[tex]Range = 68 - 32[/tex]

[tex]Range = 36[/tex]

Next, we will make use of 4 classes. So, we divide range by 10 to get the number of class. 10 represents the interval

[tex]Class= Range/10[/tex]

[tex]Class = 36/10[/tex]

[tex]Class = 3.6[/tex]

[tex]Class \approx 4[/tex]

So, we use 4 classes

Plot the frequency distribution table as follows:

The formula for volume of rectangular prism is length · width ·

height.

In other words, multiply all of the sides together.

2 · 1 · 1/4 = 2/4.

Therefore, the volume of this rectangular prism is 2/4.

Step-by-step explanation: Cause they are right next to each other and if u want me to be more specific its 6 units down :)

Answer:

The distance will be √(x2-x1)^2+(y2-y1)^2

=√(5-5)^2+(10-4)^2

=√(0)^2+(6)^2

Answer:

280 minutes

Step-by-step explanation:

Given that :

Daily dog walk routine :

Minutes walked in the morning = 15

Minutes walked in the afternoon = 25

Number of days per week = 7

The number of minutes Theo walks dog per week :

Number of days per week * (minutes walked in the morning + minutes walked in the afternoon)

7 * (15 + 25)

7 * (40)

= 280 minutes

An approximate equation for the line of best fit is y-hat = 0.018x - 24.5111.

A linear regression equation for the line of best fit would be y-hat = 0.018x - 24.5111 where

y-hat is the predicted value for the recorded weight gain (in pounds)

x is the additional daily caloric intake.

b) The pony's additional calorie intake increases, the weight gain also increases in pounds

c) Set x equal to 2300 and solve for y-hat:

y-hat = 0.018x - 24.5111

y-hat = 0.018(2300) - 24.5111

y-hat = 41.4 - 24.5111

y-hat = 16.8889

Therefore, the predicted value for the weight gain based on an additional 2300 calorie intake is 16.9 pounds.

Answer:

Bunnies= 13    Chickens=28

Step-by-step explanation:

Let's put

x = bunnies------4 legs

y = chickens-----2 legs

x + y = 41----------------x= 41-y

4x+ 2y = 108

replace in 2nd equation

4(41 - y) + 2y = 108

164 - 4y + 2y = 108

2y = 56

y = 56/2= 28

x = 41 - 28= 13

3x+y=163 2x+3y=174

Dave and Anna:

1. Income highlight:

combined take home pay of $900/week

Total income: 4(900) - because 4 weeks in most months = $3600

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

2. Expense highlights:

bi-weekly mortgage of $675

property taxes of $1800

Car expenses $160

Car insurance: $128

House insurance: $35

Saving for kids: $200

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

Expense calculations:

Mortgage bi-weekly = 675 x 2 = $1350/month

Property taxes = 1800/12 months/year = 150/month

everything else is already monthly

1350 + 150 + 160 + 128 + 35 + 200 = 2,023

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

income - expenses

$3600 - 2023 = $1,577 surplus

Answer:

Step-by-step explanation:

Since there are a total of 6 x 6 = 36 outcomes, then the probability that the sum will be greater than 10 is 3/36 = 1/12.

The probability that the resulting total is even or greater than 10 is 7/12.

Given that, two fair, six-sided dice are rolled.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favorable outcomes/Total number of outcomes

Here, sample space of two dice is

S={(1,1),(1,2),(1,3),(1,4),(1,5),(1,6), (2,1),(2,2),(2,3),(2,4),(2,5),(2,6), (3,1),(3,2),(3,3),(3,4),(3,5),(3,6), (4,1),(4,2),(4,3),(4,4),(4,5),(4,6), (5,1),(5,2),(5,3),(5,4),(5,5),(5,6), (6,1),(6,2),(6,3),(6,4),(6,5),(6,6)}

Number of favorable outcomes = 18

Total number of outcomes = 36

Probability of getting the total is even = 18/36

= 1/2

Number of favorable outcomes = 3

Probability of getting the total is greater than 10 = 3/36

= 1/12

So, probability is 1/2 + 1/12

= 6/12 + 1/12

= 7/12

Therefore, the probability that the resulting total is even or greater than 10 is 7/12.

Answer:

The surface area of the sphere is = [tex]99426.41 yd^2[/tex]

Step-by-step explanation:

The area of a sphere can be calculated using this formula:

[tex]A=4\pi r^2[/tex]

However, we have a little problem: we do not have our radius yet to utilize in the formula above.

We can get our radius from the circumference of the circle which has been given to us.

circumference = [tex]2 \times \pi \times r[/tex]

[tex]r = \frac{circumference}{2 \pi} = \frac{558.92yd}{2\pi} = 88.95yd[/tex]

We now have our radius. we can input it into equation 1 above

The Surface area of sphere = [tex]4 \times \pi \times 88/95^2 = 99426.41yd^2[/tex]
