Suppose the heights of the members of a population follow a normal
distribution. If the mean height of the population is 65 inches and the
standard deviation is 3 inches, 68% of the population will have a height within
which range?
A. 59 inches to 71 inches
B. 53 inches to 77 inches
C. 62 inches to 68 inches
D. 56 inches to 74 inches
Answer:
C; 62 to 68 inches
Step-by-step explanation:
Here, we want to get the population range that is having a probability of 68%
From the empirical rule, a measure of 1 standard deviation above the mean, with 1 standard deviation below the mean will give a total percentage of 68%
From the question;
1 standard deviation above the mean is 65 + 3 = 68
1 standard deviation below the mean is 65-3 = 62
so the range of the height of the population is 62 to 68 inches

Answer:
w+6=8 and w=2
Step-by-step explanation:
2(w+6) = 16
divide by two on both sides to remove the 2
w+6=16/2
w+6=8
-6 (remove six from both sides)
w=2

Pleas help me, please explain how you got your answer :)
Answer:
im not sure but i think its e,c,f
Step-by-step explanation:
Answer:
55 °
Here's the way i got my answer :
Complementary angles are two angles that have a sum of 90° ,therefore 35° + X = 90°
X=55° .
to get ∠DBF
180° - 90° = 90 °
to get ∠EBF
∠CBD + ∠DBE + ∠EBF = 180°
35° + 90° + ∠EBF = 180°
∠EBF = 55°
Solve this. Please and thank you.
The product of 0.014 and 100,000 is
_ ...
because the decimal point in 0.014 moves
_ ...
places to the right.
Answer:
5
Step-by-step explanation:
In the case when we multiplied 0.014 by 100,000 so it comes
= 0.014 × 100,000
= 1,400
Since The value 0.014 were times by 5 zeros.
Therefore the decimal point would move 5 places to the right
If both the base and height of the triangular base are doubled, the area of the base is multiplied by what
Answer:
the area is multiplied by 4
Step-by-step explanation:
ex. i did height and base both are two the area is two
then if both are 4 then the are is 8
I checked with base and height = 4, area = 8
base and height = 8, area =32
The points D(9, 8)and E(3, 13) are on a coordinate plane. What is theapproximate distance between points D and E?
Answer:7.8102 is the distance between those two points
Step-by-step explanation:
The area of the region between the lines y = x + 6, x = 1 and y = 0 is:
A 49 units?
B. 49/2 units squared
C.42 units squared
D. 21 units squared
E.cannot be determined
9514 1404 393
Answer:
B. 49/2 units squared
Step-by-step explanation:
The area is that of a triangle 7 units wide and 7 units high. Its area is given by the formula ...
A = 1/2bh
A = (1/2)(7 units)(7 units) = 49/2 units squared

a cone is a solid made from a disc, a point not in the same plane as the discs and all points between them. true or flase?
Answer:
False.
Step-by-step explanation:
A cone is not a solid made from a disc, a point not in the same plane as the discs and all points between them.
Mathematically, the volume of a cone is given by the formula;
[tex] V = \frac{1}{3} \pi r^{2}h[/tex]
Where;
V is the volume of the cone.
r is the radius of the base of the cone.
h is the height of the cone.
Answer: true

What are the transformations on the following
function, f (x) = -2 log4 (x + 5) - 4?
Answer:
8
Step-by-step explanation:
= f (x) = -2 log 4 (x + 5) - 4
= 4 (-2 + 5) - 4
= So you do -2 + 5 because they are in ( ) so you do it first so (-2 + 5) = 3
= So now you have 4 (3) - 4
= You do 4 and (3) because when you have a 4 by a ( ) that means you multiply.
= 4 (3) which is the same as 4 × 3 which is 12.
= then you do 12 - 4 which is 8.
= 8 is your answer.
I hope this helps.
