Answer:

Part 1) 12, 31, 9, 20, 36, 5, 22

Sort the data:

5, 9, 12, 20, 22, 31, 36

Median: 20

First Quartile: 9

Third Quartile: 31

IQR: 31 - 9 = 22

and

Part 2) 63, 68, 58, 77, 50, 49, 63, 73

Sort the data:

49, 50, 58, 63, 63, 68, 73, 77

Median: (63÷63)/2 = 63

First Quartile: (50+58)/2 = 54

Third Quartile: (68+73)/2 = 70.5

IQR: 70.5 - 54 = 16.5

You decide to put $150 in a savings account to save for a $3,000 down payment on a new car. If the account has an interest rate

zheka24 [161]

The formula is
A=p (1+r/k)^kt
A future value 3000
P present value 150
R interest rate 0.025
T time?
3000=150 (1+0.025/12)^12t
Solve for t
3000/150=(1+0.025/12)^12t
Take the log
Log (3000/150)=log (1+0.025/12)×12t
12t=Log (3000/150)÷log (1+0.025/12)
T=(log(3,000÷150)÷log(1+0.025÷12))÷12
T=119.95 years

What is the slope of -y=-x+6

Katarina [22]

Answer:

m = 1
b = -6

Step-by-step explanation:

We know that:

-y = -x + 6
y = mx + b

First, we need to change the 'y' sign.

=> -y = -x + 6
=> y = x - 6

Now, let's compare both of the equations to find slope.

=> (y = x - 6) = (y = mx + b)

We can see that the slope is 1 and the y-intercept is -6.

Conclusion:

Therefore:

m = 1
b = -6

Hoped this helped.

What fraction is equivalent to 5/9

Mama L [17]

1. Any fraction that you multiply the numerator by the same number as the denominator.
Example:

2 x 2 = 4
2. The simplest form of 24/60 is 2/5 I believe.
3. 4/9
4. 23/8

K is no greater than 9? Write>,<.

alekssr [168]

Greater than symbol is ">"
But since he mentioned "NO greater than" then it's the opposite of greater than, which means "K" is less than "9"

K<9
