Kylie works at a local music store. The store receives a shipment of new CDs in a box. In the shipment, there are 10 country CDs, 5 rock CDs, 12 hip hop CDs, and 3 jazz CDs.
What is the probability that the first CD that Kylie pulls from the box will NOT be hip hop?
Answers
Answer:
Total number of CDs= 10+5+12+3=30
Number of jazz CD= 3
Total number of outcomes that Kyle will select a jazz CD from the box= 3C1= 3!/1!2!= 3
Total number of outcomes for any CD = 30C1 = 30!/1$29! =30
Hence, the probability of picking jazz CD =3/30 = 1/10 0.1
Now since, one CD is out, the total number of CD left = 29
No. of country CD= 10
Total number of outcomes that Kyle will select a country CD from the box= 10C1= 10!/1!9!= 10
Total number of outcomes for any CD(one is out) = 29C1 = 29!/1$28! =29
Hence, the probability of picking country CD =10/29 = 0.344827

Answers
The paid amount including service fee, tip, and tax is $77.987.
what is the percentage?the percentage is value per hundred.
bill value = $59.99
service fee = 3% of $59.99 = 59.99*3/100 = $1.7997
tip = 20% of 59.99 = $11.998
tax = 7 % of $59.99 = $4.1993
total payment = 59.99+1.7997+11.998+4.1993 = $77.987

if the height of a rectangular prism is decreased by a scale factor of 1/2 how will the volume of the prism change????????
Answers
Answer:
Decrease by half.
Step-by-step explanation:
Let's say the length, width, and height is x,y,z respectively.
V = xyz
Now, when z is decreased by half, we get xyz : 2 which can either be written as (xyz) : 2 or xy(z:2)
So in short, if the height decrease by half, the volume will decrease in half.

Two angles of a triangle measure 75° and 40°. What is the degree measure of the third angle?
Answers
Answer:
the angles of a triangle always equal 180 so
75+40+x=180
115+x=180
-115
x=65
the other angle is 65
Hope This Helps!!!
65°
Step-by-step explanation:
let the third angle be x
so, sum of all angles of a triangle = 180°
x° + 75° + 40° = 180°
x + 115° = 180°
x = 180° - 115°
x = 65°

The error made by the Gabriel in calculating the change amount, is that he subtract the $2 instead of adding $2.
What is algebraic expression?
Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used represent the general problem in the mathematical way to solve them.
The expression used by the Gabriel to represent his total cost is,
[tex]2.5x+2y - 2[/tex]
As, Gabriel has to receive the change amount of $30. Thus, he has to subtract this amount from the total cost. This statement can be present as,
[tex]\rm Change=30-(2.5x+2y - 2)\\\rm Change=30-2.5x-2y + 2\\\rm Change=32-2.5x-2y[/tex]
Now, the expression used by him to represent the amount of change he should receive from $30 is,
[tex]28 -2.5x - 2y[/tex]

What is the area of the circle?The radius of a circle is the distance from the center of a circle to any point on the circle. If you place two radii end-to-end in a circle, you would have the same length as one diameter.

The area of one-quarter of the circle is given by;
[tex]\rm = \dfrac{1}{4}\times Area\ of \ a \ circle \\\\= \dfrac{1}{4}\times \pi \times radius^2\\\\ = \dfrac{1}{4}\times \pi \times 8^2\\\\= 16\pi \ in^2[/tex]

Step-by-step explanation:
We require 2 equations with the repeating numbers placed after the decimal point.
let x = 0.1212...... (1) ← multiply both sides by 10
100x = 12.1212.... (2)
subtract (1) from (2) thus eliminating the repeating numbers
99x = 12 ( divide both sides by 99 )
x = [tex]\frac{12}{99}[/tex] = [tex]\frac{4}{33}[/tex] ← in simplest form
-------------------------------------------------------
let x = 0.037037....... (1) ← multiply both sides by 1000
1000x = 37.037037..... (2)
subtract (1) from (2) to eliminate the repeating numbers
999x = 37 ( divide both sides by 999 )
x = [tex]\frac{37}{999}[/tex] = [tex]\frac{1}{27}[/tex] ← in simplest form

Answers
If she spends $42 a week on coffee and every day she spends the same amount (I don't see this in the question, only doughnuts.), then $30 can get her 30 : 42 = 5/7 of a week of coffee -> 5 days.
So, she spends 5 days on coffee -> she must also spend 5 days on doughnuts
And since she spends 30 dollars equally everyday, she spends 30 : 5 = $6 everyday on doughnuts
If the exterior angle of a regular polygon is 7.2 degrees, what is the name of that polygon?
Answer choices:
25-gon
Heptagon
50-gon
Hexagon
Answers
A regular polygon with exterior angle of 7.2 degrees is a 50-gon.
Regular polygonRegular polygon are polygon that are equiangular. This simply means they are polygon with equal angles.
The formula to find the number of sides of a polygon using exterior angle is as follows:
exterior angle = 360 / nwhere
n = number of sides
Therefore,
7.2 = 360 / n
cross multiply
7.2n = 360
divide both sides by 7.2
n = 360 / 7.2
n = 50
The polygon has 50 sides. Therefore, it is a 50-gon
