A clothing truck is shaped like a rectangular prism. The volume of the truck 15 ft cubed. The area of the base of the container
Ghella [55]

Answer: 2.5 ft

Step-by-step explanation:

The volume of a rectangular prism is given by the following formula:

V=(l)(w)(h) (1)

Where:

l is the length of the base

w is the width of the base

h is the height of the prism

On the other hand, tha area of a rectangle is:

A=(l)(w) (2)

Then, we can rewrite (1) in terms of (2):

V=(A)(h) (3)

Now, we know the value of the volume and the area of the base:

V=15ft^{3}

A=6ft^{2}

Substituting these values in (3):

15ft^{3}=(6ft^{2})(h) (4)

Isolating h:

h=2.5 ft This is the height of the truck

Prior to a special advertising campaign, 23% of all adults recognized a particular companyâs logo. At the close of the campaign
pochemuha

Answer:

The answer is "2.4049"

Step-by-step explanation:

Calculating the test of Hypothesis: H_{0}: 23\% \ \text{off all adults which reconize the compony's logo}\\\\H_{1}: \text{more than 23\% of adult recornise the compony's logo}\\\\

that is

H_{0}: p=0.23\ against \ H_{1}:p>0.01\\\\Z=\frac{P-p}{\sqrt{\frac{p(1-p)}{n}}}\sim N(0,1)\\\\

Given:

p= 0.23\\\\ \therefore \\\\1-p=0.77\\\\n=1200\\\\ P=\frac{311}{1200}=0.2591\\\\\therefore\\\\Z= \frac{0.2591-0.23}{\sqrt{((0.23)\times \frac{(1-0.23))}{1200}}}=2.4049

Z=2.576 tabled value. Because Z is 2.4049, that's less than Z stated, there is no indication that a null hypothesis is rejectable, which means that 23% of all adults record the logo of the Company.
