In the summer a large pool evaporates water at 15% per day. If the pool starts out with 25,700 gallons of water, which function

JulijaS [17]

Answer:

$y=25,700(0.85)^{x}$

Step-by-step explanation:

we know that

In this problem we have a exponential function of the form

$y=a(b)^{x}$

where

y ----> represent the pool’s loss of water

x ----> the number of days

a is the initial value

a=25,700 gal

b ----> is the base

r=15%=15/100=0.15

b=(1-r)=1-0.15=0.85

The function is equal to

$y=25,700(0.85)^{x}$

Find and interpret a 95% confidence interval to estimate the average number of bolts per box for all boxes in the population. Ro

Complete Question

The complete question is shown on the first uploaded image

Answer:

The 95% confidence interval is $49.85 < \mu < 54.15$

This means that there is 95% chance that the true population mean is within this interval

Step-by-step explanation:

From the question we are told that

The sample size is n = 30

The sample mean is $\= x = 52$

The population standard deviation is $\sigma = 6$

Given that the confidence level is 95% then the level of confidence is evaluate as

$\alpha = 100 - 95$

$\alpha = 5\%$

$\alpha = 0.05$

Next we obtain the critical value of $\frac{\alpha }{2}$ from the normal distribution table , the values is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }$

substituting values

$E = 1.96 * \frac{ 6 }{\sqrt{30} }$

$E = 2.147$

The 95% confidence interval is mathematically represented as

$\= x - E < \mu < \= x + E$

substituting values

$52 - 2.147 < \mu < 52 + 2.147$

$49.85 < \mu < 54.15$

Ryobi Limited sold a set of saws to Ace Hardware. The list price was $3,800. Ryobi offered a chain discount of 8/3/1. What's the

laila [671]

Answer: Option 'B' is correct.

Our net price will be $3357.21.

Explanation:

Since we have given that

The list price of set of saws = $3800

There are 3 successive discounts :

8%,3%,1%

So, if we apply first for 8% discount our new price becomes,

$3800\times \frac{100-8}{100}=3800\times 0.92=\$3496$

Now, if we apply 3% on our deducted price , our new price becomes ,

$3496\times \frac{100-3}{100}=3496\times 0.97=\$3391.12$

Now, we'll apply for 1% on our new deducted price , our net price becomes,

$3391.12\times \frac{100-1}{100}=3391.12\times 0.99=\$3357.21$

Hence, our net price will be $3357.21.

Therefore, Option 'B' is correct.
