honestly i got it off of a math website that i use, all of my answers from it are usually correct but if it's wrong feel free to delete it
Answer:
0.1587
Step-by-step explanation:
Here, mean=μ=100 and standard deviation=σ=16.
We have to find P(average MDI scores of 64 children > 102)=P(xbar>102).
n=64
μxbar=μ=100
σxbar=σ/√n=16/√64=16/8=2
P(xbar>102)=P((xbar-μxbar)/σxbar>(102-100)/2)
P(xbar>102)=P(z>1)
P(xbar>102)=P(0<z<∞)-P(0<z<1)
P(xbar>102)=0.5-0.3413
P(xbar>102)=0.1587
Thus, the probability that the average is greater than 102 is 15.87%

Volume of a Cuboid Formula: V = a²h
- <em>a</em> is the sides of the cube
- <em>h</em> is the height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>a</em> = 3
<em>h</em> = <em>h</em>
<em />
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of a Cuboid Formula]: V = 3²h
- Evaluate exponents: V = 9h
Answer:
C. 42x² - 3x - 9
Step-by-step explanation:
Area:
(7x + 3) (6x - 3)
7x(6x - 3) + 3(6x - 3)
42x² - 21x + 18x - 9
42x² - 3x - 9
