0=0
Step-by-step explanation:
Answer: 20
H(c) = 6.4 + 0.6c
<u>6.4</u> is the constant.
When the height of the cups is <u>18.4</u> the function is:
18.4 = 6.4 + 0.6c
Then, you add <u>6.4</u> from both sides
18.4 - 6.4 + 6.4 = 6.4 + 0.6c - 6.4 + 6.4
Simplify
18.4 = 6.4 + 0.6c
Switch sides
6.4 + 0.6c = 18.4
Multiply both sides by <u>10</u>
6.4 x 10 + 0.6c x 10 = 18.4 x 10
Refine
64 + 6c = 184
Subtract <u>64</u> from both sides
64 + 6c - 64 = 184 - 64
Simplify
6c = 120
Divide both sides by <u>6</u>
6c/6 = 120/6
c = <u>20</u>
The life span would be 24 months.
The formula for z-scores is:
![z=\frac{X-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D)
Using the information we're given we have:
![-3=\frac{X-48}{8}](https://tex.z-dn.net/?f=-3%3D%5Cfrac%7BX-48%7D%7B8%7D)
Multiply both sides by 8 to cancel it:
-3(8) = ((X-48)/8)*8
-24 = X-48
Add 48 to both sides:
-24+48 = X-48+48
24=X
Answer:
-19
Step-by-step explanation:
3x+2 = -55
-2 -2
3x = -55-2
3x = -55+-2
3x = -57
/3 /3
x=-19
Answer:
The scale factor is 1/4
Step-by-step explanation:
18/72 = 10/40 = 11/44
simplify all of those and you get 1/4.
