Answer:
94.52% or 94.52 percentile
Step-by-step explanation:
Z= (x-μ)/σ
μ is the population mean, and σ is the population standard deviation.
μ=110 and σ=25, x = 150( IQ score)
Z = 150 - 110/25
= 40/25
Z = 1.6
Probability value from Z-Table:
P(x≤ 150) = 0.9452
Converting to percentage = 0.9452 × 100
= 94.52% or 94.52 percentile

Find m angle MOP if m angle MON =4x+9 and m angle MOP =3x-3
Answer:
33
Step-by-step explanation:
Measure of ∠MOP is equals to 71.7°.
What are supplementary angles?
" Supplementary angles are those angles whose sum is equals to 180°."
According to the question,
∠MOP = 3x - 3
∠MON = 4x + 9
As ∠MOP and ∠MON has common arm OM.
Therefore, ∠MOP and ∠MON are supplementary angles.
As per definition of supplementary angles we have
∠MON + ∠MOP = 180°
Substitute the value of ∠MOP and ∠MON we get,
4x + 9 + 3x - 3= 180°
⇒7x - 6 = 180°
⇒7x = 174
⇒ x = 24.9 (round off)
Substitute the value of x in measure of ∠MOP we get,
∠MOP = 3(24.9) -3
= 71.7°
Hence, measure of ∠MOP is equals to 71.7°.

What is the solution of -4(-3m - 2) = 32?
Answer:
m=2
Step-by-step explanation:
Answer:
m=2
Step-by-step explanation:
First, write the equation and distribute.
-4(-3m-2)=32
12m+8=32
Now, subtract both sides by 8.
12m+8=32
-8 -8
12m=24
Divide both sides by 12.
12m=24
/12 /12
m=2

If you look at the diagram of the clock I put, the blue hands are the starting times and the red are the ending times. The short arrow shows the hours so we move that four numbers clockwise (to the right). The long arrow shows minutes so we move it two numbers clockwise since inbetween each number is 5 minutes and we need to go 10 minutes. We switch the am to pm since the shorter arrow moves past the 12.

Marc mixes blue and yellow paint to make his favorite shade of green, which he'll use to paint his house. He has 14 cans of blue paint and 20 cans of yellow paint when he starts. He wants the same green color every time he mixes, so the amounts of blue and yellow must always be proportional to the original mixture. On day 1, he mixes 4 cans of blue and 6 cans of yellow. On day 2, he mixes 6 cans of blue and 9 cans of yellow. 1. In simplest form, what is the ratio of blue paint to yellow paint in the mixture? Type your answer in the space below.
Answer:
The answer is 0,66
Step-by-step explanation:
Assuming he gets the exact same shade of green everyday, the ratio of blue to yellow for Marc's green color is 0,66 because 4 / 6 and 6 / 9 give the same results when calculated in decimal.

At a large university, the probability that a student takes calculus and statistics in the same semester is 0.02. The probability that a student takes statistics is 0.18, while the probability of taking calculus is 0.10. Find the probability that a student is taking calculus given that he or she is taking statistics.
Answer:
The probability that a student is taking calculus given that he or she is taking statistics is = 0.26
Step-by-step explanation:
the probability that a student is taking calculus given that he or she is taking statistics.
Let C = Calculus
S = Statistics
We solve this above Question nursing the formula;
P ( C ∪ S) = P(C) + P ( S ) - P ( C ∩ S)
From the question,
P(C) = 0.10
P( S ) = 0.18
P ( C ∩ S) = 0.02
P ( C ∪ S) = ???
P ( C ∪ S) = 0.10 + 0.18 - 0.02
= 0.28 - 0.02
= 0.26
Convert to scientific notation.

Hendrick's Honda is having a contest to win a new Honda Civic. To win a chance at the car, you must guess the number of keys in a jar within 5 of the actual number. The people who are within this range get to try a key in the ignition of the Civic. Suppose there are 697 keys in the jar.
Answer:
The valid range is 697 to 702
Step-by-step explanation:
The question is incomplete; However, the requirement would likely be to determine the valid range which users can guess
Given
[tex]Keys = 697[/tex]
[tex]Difference = 5[/tex]
First, we need to determine the minimum
[tex]Minimum = Keys - Difference[/tex]
[tex]Minimum = 697 - 5[/tex]
[tex]Minimum = 697[/tex]
Next, we determine the maximum
[tex]Maximum = 697 + 5[/tex]
[tex]Maximum = 702[/tex]
Hence:
The valid range is 697 to 702

Answer:
Measure 1 is 112º
You know that 112º is the closest answer because you can see the angle is obtuse. And obtuse is an angle less than 180 but more than 90º
Step-by-step explanation:
So a straight line is equal to 180º so just set the equations equal to 180. Your final equation should look like (3x + 22) + (2x + 8) = 180
Now all you have to do is solve for x.
3x + 22 + 2x + 8 = 180
Combine like factors
3x + 2x = 5x
22 + 8 = 30
Now your equation should look like 5x + 30 = 180
Subtract 30 from both sides. -30 -30
----------
150
So now the equation should look like 5x = 150
Divide both sides by 5, 150/5 = 30
SO x = 30
Plug 30 in to the equation to check your answer
(3*30 + 22) = 112
(2*30 + 8) = 68
112 + 68 = 180
