The diagram shows the net of a juice box. The box is a rectangular prism.

Hoochie [10]

Answer:

269.6 square centimeters

Step-by-step explanation:

The correct question is

The diagram shows the net of a juice box. the box is a rectangular prism. what is the surface area of the juice box? 6.4 cm 4 cm 10.5 cm

we know that

The surface area of a rectangular prism is equal to

$SA=2B+PH$

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

we have

$L=6.4\ cm\\W=4\ cm\\H=10.5\ cm$

Find the area of the base B

$B=LW$

substitute the given values

$B=(6.4)(4)=25.6\ cm^2$

Find the perimeter of the base P

$P=2(L+W)$

substitute the given values

$P=2(6.4+4)=20.8\ cm$

Find the surface area

$SA=2B+PH$

substitute

$SA=2(25.6)+(20.8)10.5=269.6\ cm^2$

In a study of the accuracy of fast food drive-through orders, one restaurant had 36 orders that were not accurate among 324 ord

tia_tia [17]

Answer:

We do not have sufficient evidence to reject the claim that ,the rate of inaccurate orders is equal to 10%.

Step-by-step explanation:

We want to use a 0.01 significance level to test the claim that the rate of inaccurate orders is equal to 10%.

We set up our hypothesis to get:

$H_0:p=0.10$ ------->null hypothesis

$H_1:p\ne0.10$ ------>alternate hypothesis

This means that: $p_0=0.10$

Also, we have that, one restaurant had 36 orders that were not accurate among 324 orders observed.

This implies that: $\hat p=\frac{36}{324}=0.11$

The test statistics is given by:

$z=\frac{\hat p-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }$

We substitute to obtain:

$z=\frac{0.11-0.1}{\sqrt{\frac{0.1(1-0.1)}{324} } }$

This simplifies to:

$z=0.6$

We need to calculate our p-value.

P(z>0.6)=0.2743

Since this is a two tailed test, we multiply the probability by:

The p-value is 2(0.2723)=0.5486

Since the significance level is less than the p-value, we fail to reject the null hypothesis.

We do not have sufficient evidence to reject the claim that ,the rate of inaccurate orders is equal to 10%.
