Mathematics

vagabundo [1.1K]3 years ago
6 0

Answer:

205

Step-by-step explanation:

Were gonna start by writing an equation (121+184+x)/3=170 because were adding a 3rd value to the average and x is going to be our value that were looking for. If you solve that, you get 205. Hope this helps.

What is the slope of the linear relationship shown in this table of values?
KATRIN_1 [288]

Answer:

B

Step-by-step explanation:

To find the slope m use any 2 ordered pairs from the table.

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 4, 11) and (x₂, y₂ ) = (2, - 1)

m = \frac{-1-11}{2+4} = \frac{-12}{6} = - 2 → B

A study has shown that the daily amount of milk produced by a dairy cow is normally distributed, with a mean of 6.2 gallons and
V125BC [204]

Answer:

5.5 gallons to 6.9 gallons

Step-by-step explanation:

Daily a cow

produces a mean of 6.2 gallons (average

of 6.2 gallons, meaning they already

found the mean, "averaged" it out for

you) with a deviation of 7 gallons ("give

or take" .7 gallons). On any given day

(throw these words out) 68% of the cows

(don't need this information to answer

the question either, thrown in to confuse

you) will produce an amount of milk

within which of the following ranges?

Just subtract the deviation ("give or

take number").7 gallons from the mean

(average (already determined)) 6.2

gallons which is 5.5 gallons THEN add

the deviation ("give or take number").

7 gallons to the mean (average (already

determined)) 6.2 gallons which is 6.9

gallons. Your answer is A 5.5 gallons to

6.9 gallons. You don't even have to go

crazy on the math on this question you

can rule them all out but A immediately

with subtracting .7 from 6.2.

hope it helps!

A cylindrical jar's lid has a radius of 4 inches. If the volume is 351.68 in , approximately what is the height of the jar?
balu736 [363]

Answer:

7 inches

Step-by-step explanation:

The volume of a cylinder is calculated using

V = \pi {r}^{2}h

where r =4 inches is the radius and V=351.68 is the volume.

To find the height of the jar, we substitute these values and solve for h.

351.68 = 3.14 \times  {4}^{2}  \times h

351.68 = 50.24h

Divide both sides by 50.24 to get:

h =  \frac{351.68}{50.24}

h=7 inches

Therefore the height of the jar is 7 inches
