Philip has a box of crayons. 45 are yellow, 12 are green, 25 are blue, and 8
are red. If Philip selects a crayon at random, what is the probability of not
picking a green? *
a. 1/2
b. 5/18
c. 2/15
d. 13/15
Answer:
option d
Step-by-step explanation:
First we find the probability of getting green, then we can subtract the result from 1 to find the probability of not getting the green crayon
P( green )
[tex]\frac{12}{45+12+25+8} \\= \frac{2}{15}[/tex]
P '(green) = 1 - 2/15
= 13/15

The volume of a sphere can be calculated by V = 4/3 * pi If the volume is 113.04 cm ^ 3 what is the radius?
Answer:
2.99 cm
Step-by-step explanation:
V= [tex]\frac{4}{3}[/tex](pi)(r^3)=113.04cm^3
113.04/ [tex]\frac{4}{3}[/tex](pi) = r^3 = 26.99

Arianna solved a fraction division problem using the rule " multiply by the reciprocal ". Her work is shown below 2/3 divided by 4/5 2/3 x 4/5 = 8/15
Answer:
2/3 divided by 4/5 = 5/6
Step-by-step explanation:
Arianna working:
2/3 divided by 4/5
= 2/3 x 4/5
= 8/15
Correct working:
2/3 divided by 4/5
= 2/3 ÷ 4/5
Multiply 2/3 by the reciprocal of 4/5
= 2/3 × 5/4
= (2*5) / (3*4)
= 10/12
= 5/6
2/3 divided by 4/5 = 5/6
Arianna's mistake was she didn't multiply by the reciprocal of 4/5

Solve the rational inequality x-2/x + x+2/x+3 < 3/2 represent your answer using a number line and using interval notation
Answer and explanation:
To solve the inequality x-2/x + x+2/x+3 < 3/2 we have to first simplify the expressions on the left side of the inequality sign. And so we multiply x by the expressions on the left side to eliminate fractions:
=x(x-2/x)+x(x+2/x)+x(3)< 3/2
=x-2+x+2+3x < 3/2
=5x < 3/2
x < 3/2/5
x < 3/2×5/1
x < 15/2
x < 7 1/2 or 7. 5
pls help! In the figure below, m∠ABC = 57 degrees and m∠DAB =116 degrees. What is m∠ABC?
Answer:
59°
Step-by-step explanation:
116-57=59
the outside angle is the 2 inner angles added together
Answer:
59 degrees
Step-by-step explanation:
you can use angle DAB to find out angle BAC by subtracting 180 and 116 to get 64
add 57 and 64 to get 121
subtract 180 and 121 to get 59 degrees.

On a unit test in a statistics class, the teacher determines that the mean test grade was 77.5 with a standard deviation of 5.2. One student’s test grade was 91. What is the z-score for the student’s test?
–5.20
–2.60
2.60
5.20
Answer:
2.60
Step-by-step explanation:
z-score is the difference between the score and mean, divided by the standard deviation.
[tex]z = \frac{x - \mu}{\sigma}[/tex]
[tex]z = \frac{91-77.5}{5.2} = \frac{13.5}{5.2} \approx 2.596[/tex]
So 2.6 is an answer close enough.

Answer:

-21
12
Step-by-step explanation:
can i get brainly
Answer:
- 6, - 21, 12
Step-by-step explanation:
(1)
2x - 7 = - 19 ( add 7 to both sides )
2x = - 12 ( divide both sides by 2 )
x = - 6
(2)
[tex]\frac{x}{-3}[/tex] + 5 = 12 ( subtract 5 from both sides )
[tex]\frac{x}{-3}[/tex] = 7 ( multiply both sides by - 3 to clear the fraction )
x = - 21
(3)
[tex]\frac{3}{4}[/tex] x - 5 = 4 ( add 5 to both sides )
[tex]\frac{3}{4}[/tex] x = 9 ( multiply both sides by 4 to clear the fraction )
3x = 36 ( divide both sides by 3 )
x = 12

Someone please! Check the answer twice! I just want one wrong and that’s it please! NO FILES I SWEAR IF SOMEONE ADDS A FILE THEIR GETTIN LA CANCLETA
Answer:
x = 55, because if you look the whole entire bar is 180° in total but you dont have to worry about that because that's not what the question is wanting you to look at, If you look really close there is a half and half on both sides so that means there is a 90° angle so you would have to take 90-35 and that is what gives you your missing angle which is 55.

Matthew is planning to build a right triangular flower bed as shown below. He has set up the flower bed so that the following is true. Which of the following statements about the flower bed is true?
Find the area of this shape *
Answer:
134.1 ft²
Step-by-step explanation:
Fine the area of the square first, then subtract the area of the circle to find the area of the shaded part.
The area of the square
= 25²
= 625 ft²
The radius of the circle
= 25 ÷ 2
= 12.5 ft
The area of the circle
= π × 12.5²
= 490.87385...
= 490.9 ft² (rounded up to the nearest tenth)
The area of the shaded part
= 625 - 490.9
= 134.1 ft²

A normal distribution of 10 and a standard of 1. What is the probability of selecting a number that is at most 9?
Answer:
0.15866
Step-by-step explanation:
The term at most 9 means = less than or equal to 9
This represented as x ≤ 9
We solve using the z score formula
z = (x-μ)/σ, where
x is the raw score = ≤ 9
μ is the population mean = 10
σ is the population standard deviation = 1
z = 9 - 10/1
z = -1
Probability value from Z-Table:
P(x ≤ 9) = 0.15866
Therefore, the probability of selecting a number that is at most 9 is 0.15866
The temperature was 48°F and dropped 15° in two hours.
What was the temperature after the change?
Answer:
33 degrees Fahrenheit.
Step-by-step explanation:
If the temperature was 48 degrees, and it dropped 15, that means the initial temperature was subtracted by 15.
48 - 15 = 33.
Answer:
33°F
Step-by-step explanation:
The initial temperature was 48°F. Then, it dropped by 15°.
I am assuming that both values are given in the same unit.
48 - 15 = 33
The temperature should be 33 degrees now.
Hope this helps.
