7 0

Answer: C. $(2, \sqrt{5})$

Step-by-step explanation:

The x coordinate is 2, which is 2 units right of (0, 0)

- √5 is the y coordinate

- (√5) = - (2.23) = -2.23

The y coordinate is -2.23 or 2.23 down from (0, 0)

The rest of the ordered pairs are slightly off the edge of the circle.

Brandon buys a radio for 48.43 dollars in a state where the sales tax is 7%

Elza [17]

Answer:

Given : Brandon buys a radio for $43.99 .sales tax rate is 7%.sales tax is a consumption tax imposed by the government on the sale of goods and services.

Let the price of Radio before the sales tax be $x. Sales tax on $x is 7% x.

Price before sales tax + Amount of sales tax= Cost of Radio.

x+7%x =43.99

Or x+0.07x=43.99

1.07x=43.99

Dividing both sides by 1.07.

x= 41.11

Cost of Radio before tax = $41.11

Sales tax paid = 43.99-41.11= 2.88

Tax paid = $2.90 (To the nearest cent)

Apple weights are normally distriuted with a mean 0.33 pounds and and standard deviation of 0.06 pounds. Jermaine went to the st

maksim [4K]

Using the normal distribution, it is found that 10.56% of the apples weigh less than Jermaine's apple.

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

In a normal distribution with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

It measures how many standard deviations the measure X is from the mean.
After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X, that is, the proportion of measures that are less than X.

In this problem:

Mean of 0.33 pounds, thus $\mu = 0.33$ .
Standard deviation of 0.06 pounds, thus $\sigma = 0.06$ .
The proportion that is less than 0.25 pounds is the p-value of Z when X = 0.25, thus:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{0.25 - 0.33}{0.06}$

$Z = -1.25$

$Z = -1.25$ has a p-value of 0.1056.

0.1056 x 100% = 10.56%.

10.56% of the apples weigh less than Jermaine's apple.

The regular price of a child's entry ticket to a water park is $9 less than that for an adult's. The park offers half off all en

ser-zykov [4K]

The regular price of a child's ticket is $51

Explanation

If $x$ represents the regular price of an adult ticket, then the regular price of a child's ticket $=(x-9)$

Given equations is: $132=\frac{1}{2}x+2(x-9)$

Solving the above equation, we will get...

$132=\frac{1}{2}x+2(x-9)\\ \\ 132=\frac{1}{2}x+2x-18 \\ \\ 132=\frac{5}{2}x-18\\ \\ 132+18=\frac{5}{2}x\\ \\ 150= \frac{5}{2}x\\ \\ 300=5x\\ \\ x= \frac{300}{5}=60$

So, the regular price of a child's ticket $=x-9=60-9= 51$ dollar.
