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:

<u><em>The correct question is</em></u>

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

<em>Find the area of the base B</em>

B=LW

substitute the given values

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

<em>Find the perimeter of the base P</em>

P=2(L+W)

substitute the given values

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

<em>Find the surface area</em>

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%.
