Answer:

It will take her 4 1/3 hours

Step-by-step explanation: so you know you needed to add 4 and 1/3 and you turn the 4 into 4/1 and 1/3 and since it adding you have to have the same denominator and you multiply 1x3 and if you do it on the bottom you have to do it on top so you also do 4x3 and 4x3 is 12 and one 1x3 is 3 and so you don't have to have to do it on the other fraction because now they have the same denominator now and now you add 12/3 + 1/3 and you shall get 13/3 and then you divide 13 divided by 3 and you shall get 4 1/3 and that shall be your answer.

hope it helps you!

alex41 [277]

Answer:

224 in^3

Step-by-step explanation:

The foruma appropriate to the calculation of the cone's volume is ...

V = (1/3)Bh

where B represents the area of the base and h represents the height.

For your numbers, this is ...

V = (1/3)·(48 in^2)(14 in) = (16 in^2)(14 in) = 224 in^3

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

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