What is the unit rate for 360 customers in 30 days

Lunna [17]

Unit rate always have the denominator of 1 so:
$\frac{360}{3}$ = 360 ÷ 30 = 12 customer in 1 day so the answer is:
$\frac{12}{1}$ 12 is costumer and 1 is day.

A weather balloon ascended from an elevation of 18 feet below sea level to an elevation 19 1/2 feet above sea level. What distan

Misha Larkins [42]

Answer:

The ballon rose a distance of 37 1/2 feet

Step-by-step explanation:

Here, we are interested in calculating the level of ascent of the weather balloon.

From the question, we are told that the ballon made a transition from below the sea to above the sea.

Now to calculate the total distance, we shall

be adding the distances below the sea and the distances above;

Mathematically, that would be;

18 feet + 19 1/2 feet = 37 1/2 feet

Jose wants to buy his friends pizza at lunch. He has $36 to spend. The pizza costs $2.25 per slice. Which equation could be used

Natali5045456 [20]

Answer:

36 = 2.25(x)

Number of slices = 16 slice

Step-by-step explanation:

Given:

Total amount spend = $36

Cost of each slice = $2.25 per slice

Number of slices = x

Find:

Equation

Computation:

Total amount spend = Cost of each slice × Number of slices

36 = 2.25(x)

x = 16

Number of slices = 16 slice

noted psychic was tested for extrasensory perception (ESP). The psychic was presented with 400 cards face down and asked to dete

adelina 88 [10]

Answer:

A sample of 11352 is needed.

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 $1 - \frac{\alpha}{2}$ .

The margin of error is given by:

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

For this problem, we have that:

400 cards, 120 cases were correct. So

$p = \frac{120}{400} = 0.3$

95% confidence level

So $\alpha = 0.05$ , z is the value of Z that has a pvalue of $1 - \frac{0.05}{2} = 0.975$ , so $Z = 1.96$ .

How large a sample n would you need to estimate p with margin of error 0.01 and 95% confidence

We would need a sample of size n, and n is found when $M = 0.01$ . So

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

$0.01 = 2.325\sqrt{\frac{0.3*0.7}{n}}$

$0.01\sqrt{n} = 2.325\sqrt{0.3*0.7}$

$\sqrt{n} = \frac{2.325\sqrt{0.3*0.7}}{0.01}$

$(\sqrt{n})^2 = (\frac{2.325\sqrt{0.3*0.7}}{0.01})^2$

$n = 11351.8$

Rounding up

A sample of 11352 is needed.

If a coin is flipped five times, the probability of getting heads all five times is ___________.

sergejj [24]

5 coin tosses. This means,

Total observations =25=25

Required outcome → 5 Heads {H,H,H,H,H}

This can occur only ONCE!

Thus, required outcome =1=1

Probability (5 Heads) =125=132
