To find a percent of a number, multiply the percent by the number.
To convert a percent to a decimal, move the decimal point 2 places tot he left.

2.2% of 18 2/11 =
= 2.2% * 18 2/11
= 0.022 * 200/11
= 0.4

Suppose you invest $75 a month in an annuity that earns 48% APR compounded monthly. How much money will you have in this account

il63 [147K]

Answer:

The money after 3 years is $5819.8735

Step-by-step explanation:

We are given

monthly payment =$75

so, P=75

annuity that earns 48% APR

so, r=48%

Since, it is compounded monthly

so,

$i=\frac{48}{12} =4$ %

i=0.04

$n=12\times 3=36$

now, we can use annuity formula

$FV=P[\frac{(1+i)^n-1}{i} ]$

where

FV is future value

now, we can plug values

$FV=75[\frac{(1+0.04)^{36}-1}{0.04} ]$

we get

$FV=5819.8735$

The money after 3 years is $5819.8735

The table shows the results of a survey in which 10th-grade students were asked how many siblings (brothers and/or sisters) they

lesantik [10]

Answer:

70%

Step-by-step explanation:

Given

Number of Siblings: || 0 || 1 || 2 || 3

Number of Students: || 4 || 18 || 10 || 8

Required

Determine the probability of a student having at least one but not more than 2 siblings

First, we have to determine the total number of 10th grade students

$Total = 4 + 18 + 10 + 8$

$Total = 40$

The probability of a student having at least one but not more than 2 siblings = P(1) + P(2)

Solving for P(1)

P(1) = number of students with 1 sibling / total number of students

From the given parameters, we have that:

Number of students with 1 sibling = 18

So:

$P(1) = \frac{18}{40}$

Solving for P(2)

P(2) = number of students with 2 siblings / total number of students

From the given parameters, we have that:

Number of students with 2 siblings = 10

So:

$P(2) = \frac{10}{40}$

$P(1) + P(2) = \frac{18}{40} + \frac{10}{40}$

Take LCM

$P(1) + P(2) = \frac{18 + 10}{40}$

$P(1) + P(2) = \frac{28}{40}$

Divide numerator and denominator by 4

$P(1) + P(2) = \frac{7}{10}$

$P(1) + P(2) = 0.7$

Convert to percentage

$P(1) + P(2) = 70\%$

Hence, the required probability is 70%
