You have to multiply 3x3 since it says 3^2 then subtract 9 from 10 you get 1. Then you have to diving 8x and 1 and you get 1/8
Answer:
Step-by-step explanation:
<em>Let the angle be x</em>
Tan x = 
Where opposite = 48, Adjacent = 50
Tan x = 
Tan x = 0.96
x = 
x = 43.8 degrees
It decreased $7 in the last 2 days
Answer:
0.01
Step-by-step explanation:
Using the z score formula
z = (x-μ)/σ,
where x is the raw score = 135
μ is the population mean = 100
σ is the population standard deviation = 15
z = 135 - 100/15
z = 2.33333
P-value from Z-Table:
P(x<135) = 0.99018
P(x>135) = 1 - P(x<135)
P(x > 135) = 1 - 0.99018
= 0.0098153
Approximately to 2 decimal places
= 0.01
Therefore, the proportion of the population for the following IQ score of 135 is 0.01
Answer:
x = 169º
Step-by-step explanation:
So we know that a straight line equals 180º. Now we have to come up with an equation. We're given 11º so the equation should look like:
x + 11 = 180 or 180 - 11 = x
I'll solve for both.
x + 11 = 180
-11 -11
x = 169
180 - 11 = x
180 - 11 = 169
x = 169
