Volume of a cube is calculated by multiplying it's length, width and height

But, in a cube all the sides are equal. Therefore, the values of length, width and height of a cube are same .

➲ Now, calculating the volume of given cube:

‎➙ V = length × width × height

‎➙ V = ( 3x + 2 ) × ( 3x + 2 ) × ( 3x + 2 )

➙ V = ( 3x + 2 )³

➙ V = ( 3x )³ + ( 2 ) ³ + 3 ( 3x ) ( 2 ) ( 3x + 2)

➙ V = 27x³ + 8 + 18x ( 3x + 2 )

➙ V = 27x³ + 8 + 54x² + 36x

➙ V = 27x³ + 54x² + 36x + 8

Suppose a marketing company wants to determine the current proportion of customers who click on ads on their smartphones. It was

andrezito [222]

Answer:

The 92% confidence interval for the true proportion of customers who click on ads on their smartphones is (0.3336, 0.5064).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

$n = 100, p = 0.42$

92% confidence level

So $\alpha = 0.08$ , z is the value of Z that has a pvalue of $1 - \frac{0.08}{2} = 0.96$ , so $Z = 1.75$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.42 - 1.75\sqrt{\frac{0.42*0.58}{100}} = 0.3336$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.42 - 1.75\sqrt{\frac{0.42*0.58}{100}} = 0.5064$

The 92% confidence interval for the true proportion of customers who click on ads on their smartphones is (0.3336, 0.5064).

Help me I’m trying to finish this work before I get kick out

The answer for the first box is 90

Why? Because this is from the expression 90x+1500. The 90x means the slope is 90. So each time x goes up by 1, the value of y goes up by 90

----------------------------

The answer to the second box is 1500

If you were to plug in x = 0, then
y = 90x+1500
y = 90*0+1500
y = 1500
So he earns $1500 for selling 0 copies
