A cow can give 5 gallons of milk if it eats 2 pounds of grass. Express x in terms of y, where y is the number of gallons of milk

Crank

Answer:y=2.5 x

Step-by-step explanation:

Given

Cow give 5 gallon of milk if it eats 2 pound of grass

i.e. it gives 2.5 gallon of milk if it eats 1 pound of grass

So we can say cow given 2.5 times of milk in gallon for each pound it eats

If cow eats x pounds of grass then it must yield 2.5 times of milk

Suppose milk is denoted by y

therefore we can write

y=2.5 x

Therefore y=2.5 x represent the relation between grass and milk produced

8. Lisa types 6 pages in 36 minutes. Frank types 5 pages in 30 minutes. Do they type at the same rate? Use a proportion to expla

qaws [65]

Answer:

Yes

Step-by-step explanation:

Lisa and Frank type at the same rate.

They both type 1 page every six minutes.

Lisa types 6 pages every 36 minutes, and if we divide the minutes by the pages, we get

$\frac{36}{6} = 6$

And Frank types 5 pages ever 30 minutes, when we divide we get

$\frac{30}{5} = 6$

The number of square feet per house are normally distributed with a population standard deviation of 137 square feet and an unkn

pshichka [43]

Answer:

Step-by-step explanation:

Given that X, the number of square feet per house is N(mean, 137)

Sample size = 19

Sample mean x bar =1350 sq ft

Since population std dev is given,

std error of sample = $\frac{137}{\sqrt{19} } \\=31.43$

Since sample size is small, t critical value can be used

df = 18

t value for 80% two tailed = 1.333

Margin of error = ±1.333(std error) = ± $1.333*31.43\\=41.896$

Confidence interval = sample mean ±margin of error

= $1350-41.896,1350+41.896\\=(1308.104,1391.896)$
