Aidan writes numbers on his ten fingers as 5, 7, 9, 11, 13, 15, 16, 19, 22, 23. What is the probability of picking an even numbe

faltersainse [42]

It would be 2/10, or 1/5, since two out of the 10 numbers are even. 2/10 simplifies to 1/5, since there is 1 for every 5 numbers.

We could turn this into a percentage by dividing 1 by 5, which gives us 0.2. Then we can multiply by 100 to get 20.

So, our probability of choosing an even number is:
2/10
OR
1/5
OR
20%

Hope I could help!

The Johnsons are buying their first home. They are contemplating two similar loans. The first is a 30-year loan for $150,000 at

OLEGan [10]

Johnson's will pay by the end of the 20-year loan $326,807.25

Johnson's will pay by the end of the 30-year loan $512,109.68

Step-by-step explanation:

The formula for compound interest, including principal sum is

$A=P(1+\frac{r}{n})^{nt}$ , where:

A is the future value of the investment/loan, including interest
P is the principal investment amount (the initial deposit or loan amount)
r is the annual interest rate (decimal)
n is the number of times that interest is compounded per unit t
t is the time the money is invested or borrowed for

The Johnson's are buying their first home. They are contemplating

two similar loans

The first is a 30-year loan for $150,000 at an interest rate of 4.1% APT

compounded monthly

∴ P = $150,000

∴ r = 4.1% = (4.1/100) = 0.041

∴ n = 12 ⇒ compounded monthly

∴ t = 30

- Substitute all of these values in the formula above

∴ $A=150,000(1+\frac{0.041}{12})^{(12)(30)}$

∴ A = $512,109.68

Johnson's will pay by the end of the 30-year loan $512,109.68

The second is a 20-year loan for a $150,000 at an interest rate of 3.9%

APR compounded monthly

∴ P = $150,000

∴ r = 3.9% = (3.9/100) = 0.039

∴ n = 12 ⇒ compounded monthly

∴ t = 20

- Substitute all of these values in the formula above

∴ $A=150,000(1+\frac{0.039}{12})^{(12)(20)}$

∴ A = $326,807.25

Johnson's will pay by the end of the 20-year loan $326,807.25

Drag each label to the correct location on the image.

dolphi86 [110]

Answer:

The answer will be listed below.

Step-by-step explanation:

No Solution: -2z+2+4z=16/5+2z-6/5; 5r+2=6r+3-r

One Solution: 3/2x+2.3-1/2x=4.3+x; 2x+2/3=2x+4/5-4x; 32p-2.5+2.1p=5p-7/2

Infinite Solution: 17/4+4.2y-9/4=2.2y+6+2y-4

Note: Remember that infinite solution is like 1=1 or 5x+2=5x+2. No solution is where it's like 0=1. 1 solution is where it's like x=2.

A telephone pole is perpendicular to the ground. What is the size of the angle between the ground and the telephone pole? How do

90 degrees
perpendicular just means the angle between the two planes, in this case the ground and the pole, is 90 deg :)
