Answer:
29 and -18
Step-by-step explanation:
f(x)= -3x+12
f(-9)= -3(-9)+2
f(-9)= 27+2
f(-9)= 29
g(x)= x2
g(-9)= -9(2)
g(-9)= -18
Answer:
81.82%
Step-by-step explanation:
First we need to convert the X score to Z score using the formula;
Z = X-µ/σ
If X = 225.76
Z = 225.76-256.43/27.11
Z = -30.67/27.11
Z = -1.1313
Similarly if X = 300.35
Z = 300.35-256.43/27.11
Z = 43.92/27.11
Z = 1.6201
Hence the required z score is P(-1.1313 ≤ Z ≤ 1.6201)
Checking the normal distribution table;
P( Z ≤ 1.6201) = 0.9474 = 94.74%
P(Z ≤ -1.1313) = 0.1292 = 12.92%
P(-1.1313 ≤ Z ≤ 1.6201) = 94.74 - 12.92
P(-1.1313 ≤ Z ≤ 1.6201) = 81.82%

Answer:
yum
Step-by-step explanation:
Slope form: y=mx + b
slope is 2/5, fill into equation
Y = 2/5x + b
Plug in point to find b
1 = 2/5(0) + b
1 = 0 + b, b = 1
The answer is A. Y = 2/5x + 1
