A teacher wanted to know how well the gifted students in here class perform relative to her other classes. She administers a sta

Olegator [25]

Answer: 30.85%.

Step-by-step explanation:

Let X denotes the score of random student.

Given: $\mu = 50$ and $\sigma=10$

We assume that scores are normally distributed.

Then , the probability that a a student score higher than 55:

$P(X>55)=P(\dfrac{X-\mu}{\sigma}>\dfrac{55-50}{10})\\\\=P(Z>0.5) \ \ [Z=\dfrac{X-\mu}{\sigma}]\\\\=1-P(Z$

Hence, the percent of students have a higher score than hers is 30.85%.

Whar is 10.034 rounded to the nearest tenth

VLD [36.1K]

Answer: 10.0

Step-by-step explanation: In this problem, we are asked to round 10.034 to the nearest tenth. It's important to understand that the tenths place is 1 place to the right of the decimal point. So the digit in the rounding place is 0.

Next, look at the digit to the right of the rounding place which in this case is 3. Since the digit to the right of the rounding place, 3, is less than 5, we round down.

This means that the digit in the rounding place, 0, stays the same and we change all digits to the right of the rounding place to 0.

So 10.034 rounded to the nearest tenth is 10.000 or just 10<em>.</em>0 since we can drop zeroes at the end of a decimal.

Rewrite each equation in slope intersept form to 4x -y=7

Bad White [126]

Answer:

y = 4x-7

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

4x-y = 7

Subtract 4x from each side

-y = -4x+7

Multiply each side by -1

y = 4x-7

Fiona has a coupon for $3 off the price of her meal at a local fast food establishment. her favorite meal is on sale at a specia

Helen [10]

The Original price of the meal was $12.16.

Discount Percent is defined as the discount given on the product per hundred .

For Example . if there is 10% discount on a price of $100.

The final amount will be $90.

Final amount paid by Fiona = $8.25

percentage discount = 10%

Let the original amount be x.

According to the question ;

x - 10% of x = 8.25

$x-\frac{10}{100} *x=8.25\\ \\ \frac{100x-10x}{100} =8.25\\ \\ \frac{90x}{100} =8.25\\ \\ x=\frac{8.25*100}{90}\\ \\ x=\frac{825}{90} \\ \\ x=9.16$

Since Fiona also had a discount coupon of $3.

The original amount will be $9.16+$3=$12.16.

Therefore , The original price of the meal was $12.16.
