Answer: All but statement 1
Step-by-step explanation:
In order to get 36 as an outcome, the numbers need to multiply together in order to get 36. In other words, a*b*c*d*....= desired outcome number. In statement 1, 3*9=27, and therefore not 36 outcomes. The rest do multiply to 36.
Answer:
<h2>length = 22 inches</h2><h2>width = 8 inches</h2>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 60 in
The statement
the length of a rectangle is 6 inches more than twice it's width is written as
l = 6 + 2w
Substitute the statement into the above formula
That's
60 = 2( 6 + 2w) + 2w
60 = 12 + 4w + 2w
6w = 60 - 12
6w = 48
Divide both sides by 6
w = 8
Substitute w = 6 into l = 6 + 2w
That's
l = 6 + 2(8)
l = 6 + 16
l = 22
The dimensions are
length = 22 inches
width = 8 inches

Answer:
906 inches³
Step-by-step explanation:
The volume of a triangular pyramid = 1/3 (area of base) × h
area of the base = 1/2 × 19 × 13 = 123.5 inches²
v = 1/3 × 123.5 × 22 = 905.666... ≈ 906 inches³
The volume of the triangular pyramid is 906 inches³
Hope this helps!
Answer: 0.6827
Step-by-step explanation:
Given : Mean IQ score : 
Standard deviation : 
We assume that adults have IQ scores that are normally distributed .
Let x be the random variable that represents the IQ score of adults .
z-score : 
For x= 90
For x= 120
By using the standard normal distribution table , we have
The p-value : 
Hence, the probability that a randomly selected adult has an IQ between 90 and 120 =0.6827
