I really need help with c,d and e

Mathematics
1 answer:
Zolol [24]2 years ago
7 0

Answer:

Step-by-step explanation:

By using regression line calculator,

Equation of the line of best fit,

c). y = 0.74x + 0.03

Here, x = Number of pints

y = Weight in pounds

d). We have to find the weight of 10 pints of the blueberries,

By substituting x = 10 in the equation,

y = 0.74(10) + 0.03

y = 7.4 + 0.03

y = 7.43 pounds

e). If per pound cost of the blueberries = $2.25

By substituting y = 2.25 in the equation,

2.25 = 0.74x + 0.03

x = \frac{2.22}{0.74}

x = $3.00 per pound

Therefore, cost of 10 pounds blueberries = 3 × 10

                                                                     = $30

Samantha works at an animal shelter. She decides to track the total number of kittens that are brought in. The equation k=4w+3 r
mel-nik [20]

Answer:

B

Step-by-step explanation:

The equation k=4w+3 represents the total number of kittens, where w represents <u>the number of weeks that have passed since Samantha started counting.</u>

This means options C and D are false, because they say <u>the total number of kittens that have come into the shelter</u>.

w represents the number of weeks, weeks can be counted 0 weeks, first week, second week and so on, so option B is true (the domain is all whole numbers) because 0, 1, 2, 3, ... are whole numbers.

Number of weeks can't be a negative number. Since "real numbers" include negatives, therefore, we exclude option A.

Romashka-Z-Leto [24]

Answer:

The interquartile range is <em>50.</em>

Step-by-step explanation:

To find our answer we have to first <em>quartile 1</em> and <em>quartile 3</em> are equal too. When we look at the plot <em>quartile 1  </em>is equal to <em>20,</em> <em>quartile 3 </em>is equal to <em>70</em> because it is in between <em>60</em> and <em>80</em>.  Now to find the interquartile range we will <em>subtract 70</em> from <em>20</em> and we get <em>50</em>.  Therefore, <u><em>50</em></u><em> is our answer.</em>

Is -100 rational or irational
pychu [463]

-100 is rational.

-100 can be turned into a fraction by doing the following...

Just put 1 underneath -100 and you get \frac{-100}{1}

So that means it is rational since it can be a fraction!
