x + 12 = 13
Subtract 12 from both sides
x + 12 -12 = 13 - 12
x = 1
Answer
F. 1
Answer:
10
2
Step-by-step explanation:
if x=0 => y = 2(0)+10= 10
y = mx + c
m = slope factor
=> y = 2x + 10
so, slope factor = 2

Answer:
cos R = .38
Step-by-step explanation:
First you need to find the length of the hypotenuse.
Use a squared + b squared = c squared
100 + 576 = c squared
square root of 676 is 26
CosR is adjacent over hypotenuse.
Adjacent is 10
Hypotenuse is 26
10/26 = .38
Answer:
Standard error = 0.070
Step-by-step explanation:
Formula for the standard error of the distribution of differences in sample proportions is;
σ_(A - B) = √((p_a^(1 - p_a^)/n_a) + (p_b^(1 - p_b^)/n_b))
We are given;
p_a^ = 0.48
n_a = 80
p_b^ = 0.13
n_b = 66
Thus;
σ_(A - B) = √((0.48(1 - 0.48)/80) + (0.14(1 - 0.13)/66))
σ_(A - B) = √0.00496545455
σ_(A - B) = 0.070
