Including Jose, there are eight people in his family.

SIZIF [17.4K]

Answer:

840

Step-by-step explanation:

Since the order matters, we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this question:

The first seat is Jose's.

The remaining four are organized among the other 7 members. So

$P_{(7,4)} = \frac{7!}{(7-4)!} = 840$

So the correct answer is:

840

a school district requires all graduating seniors to take a mathematics test. This year, the rest scores were approximately norm

Klio2033 [76]

A score of 85 would be 1 standard deviation from the mean, 74. Using the 68-95-99.7 rule, we know that 68% of normally distributed data falls within 1 standard deviation of the mean. This means that 100%-68% = 32% of the data is either higher or lower. 32/2 = 16% of the data will be higher than 1 standard deviation from the mean and 16% of the data will be lower than 1 standard deviation from the mean. This means that 16% of the graduating seniors should have a score above 85%.

Ginger Smith was seen in Dr. Sampson's office today for an allergic reaction to a prescribed drug. Total charges today are $100.

Anna71 [15]

Answer: Ginger Smith will have to pay $23.00

Step-by-step explanation:

When we talk about a Health Insurance, the Allowed amount $A$ is the maximum amount the Health Insurance company will cover for health care services.

So, if the health care provider charges more than this allowed amount (as in this situation with Ginger Smith), Ginger will have to pay the difference $D$ , which is calculated by:

$D=T-A$

$T=\$100.00$ are the total charges

$A=\$77.00$ is the allowed amount

$D=\$100.00-\$77.00$

$D=\$23.00$ This is the difference Ginger Smith will have to pay

Susan has a flower bed that is shaped like a right triangle. Both sides of the right angle are six feet long. What is the length

love history [14]

Answer:

From the Pythagorean Theorem we know:

hypotenuse^2 = 36 + 36

hypotenuse = square root (72)

hypotenuse = 8.48528... feet

a square painting has an area of 81x^2-90x-25. A second square painting has an area of 25x^2+30x+9. What is an expression that r

galina1969 [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

A1 ------> the area of the first square painting

A2 ----> the area of the second square painting

D -----> the difference of the areas

we have

$A1=81x^{2}-90x-25$

$A2=25x^{2}+30x+9$

case 1) The area of the second square painting is greater than the area of the first square painting

The difference of the area of the paintings is equal to subtract the area of the first square painting from the area of the second square painting

D=A2-A1

$D=(25x^{2}+30x+9)-(81x^{2}-90x-25)$

$D=(-56x^{2}+120x+34)$

case 2) The area of the first square painting is greater than the area of the second square painting

The difference of the area of the paintings is equal to subtract the area of the second square painting from the area of the first square painting

D=A1-A2

$D=(81x^{2}-90x-25)-(25x^{2}+30x+9)$

$D=(56x^{2}-120x-34)$
