A set of middle school student heights are normally distributed with a mean of 150150150 centimeters and a standard deviation of 202020 centimeters. Darnell is a middle school student with a height of 161.4161.4161, point, 4 centimeters.
Complete question :
A set of middle school student heights are normally distributed with a mean of 150 centimeters and a standard deviation of 20 centimeters. Darnell is a middle school student with a height of 161.4 centimeters.
What proportion of student heights are lower than Darnell's height?
Answer:
0.716 (71.6%)
Step-by-step explanation:
Given that :
Mean, μ = 150
Standard deviation, σ = 20
Darnell's height, x = 161.4
(x < 161.4)
We obtain the standardized score, then find the proportion using a standard normal distribution ;
Zscore = (x - μ) / σ
Zscore = (161.4 - 150) / 20
Zscore = 11.4 / 20
Z = 0.57
P(Z < 0.57) = 0.71566 (Z probability calculator)
This means that about 0.716 (0.716 * 100% = 71.6%) of student's height are lower than 161.4 centimeters
Answer: 0.11
Step-by-step explanation:
Since we know the distribution of heights is normally distributed, the probability P(X>175) can be found by calculating the shaded area above X=175 in the corresponding normal distribution:
P(X>175)≈0.11 is the answer.

What is an equation of the line that passes through the points (2, –6) and (1, -1)?
Answer:
x axis
Step-by-step explanation:
Answer:
y=-5x+4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-(-6))/(1-2)
m=(-1+6)/-1
m=5/-1
m=-5
y-y1=m(x-x1)
y-(-6)=-5(x-2)
y+6=-5(x-2)
y=-5x+10-6
y=-5x+4

IF YOU HELP ME WITH THIS YOU WILL GET 25 POINTS! LINKS=REPORTED!
Answer:
22. acute triangle
23. right triangle
24. equilateral triangle
25. right triangle
Step-by-step explanation:
let me know if any of these are wrong
-25-2x=3x
I know the answer to the problem but i´m not sure how to move the constant (-25) to the other side. When you move the constant to the right side the equation should be -2x=3x+25. How do you move a constant to the other side?
In this case I believe you would add 25 to both sides. The -25 +25 would cancel out and then +25 would be on the right.
7th Grade math if anyone knows
Answer:
30° and 150°
Step-by-step explanation:
Supplementary angles sum to 180°
sum the parts of the ratio, 1 + 5 = 6 parts
Divide 180° by 6 to find the value of 1 part of the ratio
180° ÷ 6 = 30° ← value of 1 part of the ratio , then
5 parts = 5 × 30° = 150°
smaller angle = 30°
larger angle = 150°
P = 4x + 3y
x = 5
y=-2
(a) Work out the value of P.
(b) Expand 4e(e + 2)
Answer:
P=4×5+3×-2
P= 20x-6y

Answer:
a° = 52°
b° = 64°
c° = 128°
Step-by-step explanation:
a) The 52° angle and the angle marked a° both intercept the same arc, so have the same measure.
a° = 52°
__
b) The base angles of the isosceles triangle are equal. This means they are ...
b° = (180° -52°)/2 = 128°/2
b° = 64°
__
c) The arc intercepted by angle b° is twice the measure of angle b°, so is ...
c° = 2(64°)
c° = 128°
