This is a difference of perfect squares which is of the form:
(a^2-b^2)
And which always factors to:
(a-b)(a+b)
In this case:
(5x-8)(5x+8)
Answer:
17.11%
Step-by-step explanation:
since 43.2 months is the mean, and the standard deviation is 7.7 months
that means if we take the z score:
z=(36-43.2)/7.7
now that we know how many standard deviations you are away from the mean: -0.9351
using the zscore table you can find the proportion, or you can use the calculator if you have one that can do that.
you get 0.1711 which in percentages is 17.11%
Average or round?
average: 22.35
rounded: 26 and 19

Answer:
40 degrees
Step-by-step explanation:
We know the entire angle of ABD is 70 and CBD and ABC are in it.
Since we know one of them (CBD) is 30, we can subtract 30 from 70 to find ABC. This is because the angle of ABC and CBD equal ABD.
30 + x = 70
-30 from both sides
x = 40
Answer:
y = 3x - 11
Step-by-step explanation:
Step 1:
y = mx + b Slope Intercept Form
Step 2:
y = 3x + b Input Slope
Step 3:
- 5 = 3 ( 2 ) + b Input x and y values
Step 4:
- 5 = 6 + b Multiply
Step 5:
- 11 = b Subtract 6 on both sides
Answer:
y = 3x - 11
