Suppose you borrow 13,000 for four years at 7% toward the purchase of a car.

dangina [55]

Amount borrowed, P = 13000
Interest, i = 0.07/12 per month
number of periods (months), n = 4*12 = 48

Monthly payment,
$A=\frac{P(i*(1+i)^n)}{(1+i)^n-1}$
$=\frac{13000(.07/12*(1+.07/12)^{48}}{(1+.07/12)^{48}-1}$
=311.30 (to the nearest cent)

e-lub [12.9K]

Answer:

95% of monthly food expenditures are between $110 and $190.

Step-by-step explanation:

Given : The monthly amounts spent for food by families of four receiving food stamps approximates a symmetrical, normal distribution. The sample mean is $150 and the standard deviation is $20.

To find : Using the Empirical rule, about 95% of the monthly food expenditures are between which of the following two amounts?

Solution :

At 95% of the data is between two standard deviation to left and right of the mean is given by,

To the left side, $\bar{x}-2\sigma$

To the right side, $\bar{x}+2\sigma$

We have given,

The sample mean $\bar{x}=\$150$

The standard deviation $\sigma=\$20$

Substitute in the formula,

$\bar{x}-2\sigma$

$=150-2(20)$

$=150-40$

$=110$

$\bar{x}+2\sigma$

$=150+2(20)$

$=150+40$

$=190$

Therefore, 95% of monthly food expenditures are between $110 and $190.

For every boy in an advanced math course there are 3 girls who are taking the course.

Nutka1998 [239]

Answer:

If 32 students are enrolled in the course, there would be 24 girls.

Step-by-step explanation:

Given that For every boy in an advanced math course there are 3 girls who are taking the course.

It means if there are four students in the class. There would be 3 girls and 1 boy. Thus, 75% of the students are girls.

Given that there are 32 students enrolled in the course.

75% of 32 = 75/100 × 32

= 24

Thus, if 32 students are enrolled in the course, there would be 24 girls.

ASAP PLZZZ I NEED HELP

son4ous [18]

Answer:

994.5

Step-by-step explanation:

First, you need to figure out how many people are actually attending the event. It says that there are 50% more so we are going to have to add 56% of 150 to 150.

150 x 0.56 = 84

150 + 84 = 234

Now, we have to multiply this by 4.25, because this is the cost of the food per person.

234 x 4.25 = 994.5
