A college professor teaching a class of Psychology gives the following grades during Fall semester: 15% A’s, 20% B’s, 40% C’s, and 10% D’s. The remainder of the students receive an F.
What is the probability that a randomly selected student does not earn an A in this class?
Answer:
85%
Step-by-step explanation:
Because we can see that only 15% of the class obtained A's, and the question only refers to those that did not receive A's, we can subtract the 15% of the 100% whole to get 85%. This can also be written as 85/100 or 17/20(simplified).
Tammy rents a storage shed. The storage shed is in the shape of a rectangular prism with measurements as shown. A rectangular prism has a length of 10 feet, height of 9 feet and a width of 9 feet. Select the phrase and number from the drop-down menus to correctly complete each sentence. Tammy can find the volume of the storage unit by Choose... . To completely fill the storage shed, Tammy would need Choose... Unit boxes that each measure 1 cubic foot.
Answer:
Finding the product of 9, 10 and 9 ; 810
Step-by-step explanation:
Given that :
Length = 10 feets
Width = 9 feets
Height = 9 feets
The volume of a rectangular prism is obtained by :
Length * width * height
The volume could be obtained by taking the product of 10, 9 and 9
Hence, the volume of the rectangular prism is :
(10 * 9 * 9) feet³ = 810 feet³
Number of 1 feet³ boxes = 810 feet³ / 1 feet³ = 810
In a school the number of students with blonde hair to the numberof student with brown hair is 4:5 what fraction of students have blonde hair
Answer:
4 / 9th of students have blonde hair
Step-by-step explanation:
Fraction of blonde hair students to brown hair students = 4 : 5
Fraction of students having blonde hair = Blonde hair ratio share / Total ratio
= 4 / 9th of students have blonde hair

A shopkeeper sells apples in two types of boxes, one small and one large. A large box
contains as many as 8 small boxes plus 4 loose apples. The number of apples in a
large box is given to be 100. Find the number of apples in a small box.
Answer:
12 apple in a small box.
Step-by-step explanation:
If there's 100 in a large box, then subtract the 4 loose apples to only have left 96 apples among the 8 small boxes. 96/8 is 12 apples per small box
2. A right square pyramid is inverted so it is pointing down. The pyramid’s base has an area of 100 square centimeters and the area of one face is 60 square centimeters.
a. What is the volume of the pyramid?
b. The pyramid was filled with a solution. Some of the solution was drained out the vertex of the pyramid into a cylindrical dish with a radius of four centimeters. The level of liquid in the pyramid dropped three centimeters. How deep is the solution in the dish?
Answer:
2. a. The volume of the pyramid is approximately 363.62 cm³
b. The depth of the solution in the dish is approximately 0.15046 cm
Step-by-step explanation:
2. a. A right square pyramid is a pyramid with the vertex at the top directly above the center of the base
The area of the base of the right square pyramid = 100 cm²
The area of one of the face = 60 cm²
∴ The length of the side of the base, s = √(100 cm²) = 10 cm
The area of the face = 1/2 × s × l
Where;
l = The slant height
∴ 1/2 × 10 cm × l = 60 cm²
l = 60 cm²/(5 cm) = 12 cm
l = 12 cm
The height of the pyramid, h = √(l² - (s/2)²)
∴ h = √(12² - 5²) = √(119)
The volume of the pyramid = 1/3 × Base Area × Height
∴ The volume of the pyramid, V = 1/3 × 100 cm² × √(119) cm ≈ 363.62 cm³
The volume of the pyramid, V ≈ 363.62 cm³
b. The initial level of the solution in the pyramid = The pyramid was filled with the solution
∴ The initial level of the solution in the pyramid = The height of the pyramid
The radius of the cylindrical dish into which the solution is poured, r = 4 cm
The level by which the liquid drops in the pyramid after pouring = 3 cm
Therefore, by proportion of volume, we have;
Let V₁ and 'V' represent the volume that was drained out the vertex into the cylindrical dish and the volume of the whole pyramid respectively
Therefore;
V₁/V = (3/(√119))³
V₁ = V × (3/(√119))³
V = 1/3 × 100 cm² × √(119) cm
∴ V₁ = 1/3 × 100 cm² × √(119) cm × (3/(√119))³ = 100 cm² × 1 cm × 3²/(119) = 900/119 cm³
The volume that was drained out the vertex, V₁ = 900/119 cm³
The volume of the cylindrical dish, [tex]V_d[/tex] = π·r²·h
Where h = The depth of the solution in the dish
∴ When [tex]V_d[/tex] = V₁, and r = 4 cm, we have;
π × 4² × h = 900/119
h = (900/119)/(π × 4²) ≈ 0.15046
The depth of the solution in the dish, h ≈ 0.15046 cm.

Find RT please and thank you.
RQ × RP = RS × RT
9 × ( 9 + 13 ) = 11 × RT
9 × 22 = 11 × RT
Divide sides by 11
9 × 22 / 11 = 11 × RT / 11
Simplification
9 × 2 = RT
RT = 18
Answer: RT=18
Step-by-step explanation: I’m going to be using this formula: RQ•RP=RS•RT
9•22=198
ST=7
11•18=198
Therefore RT=18

Step-by-step explanation:
In a survey of 292 students, about 9.9% have attended more than one play. Which
is closest to the number of students in the survey who have attended more than one
play?
3 students
10 students
20 students
30 students
Witch one
Answer:
30
Step-by-step explanation:
So we know that there are 292 people and 9.9% attended one play so you just find 10% of 300(approximated) which is the same thing as 30.

Linear y=mx+b Line
a. y=x b. y= -2/3x -4
Answer:
Every straight line can be represented by an equation: y = mx + b. ... The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
Step-by-step explanation:

The key to this problem is to write out the probabilities and determine which one is most likely and least likely (or impossible).
Drawing a black card from a standard deck of playing cards:
There are 52 cards in a playing deck, 26 are red and 26 are black.
[tex]\frac{26}{52}[/tex] = [tex]\frac{1}{2}[/tex]
A spinner has 5 equal sections numbered 1 through 5. You spin and land on a number less than or equal to 4.
This means that all the numbers (1, 2, 3, and 4) except 5.
[tex]\frac{4}{5}[/tex]
You roll a standard number cube and get a number less than 2.
A standard cube is from 1 to 6, and 1 is the only number on the cube that is less than 2.
[tex]\frac{1}{6}[/tex]
You roll two standard number cubes and the sum is 1.
The smallest number on a standard cube is 1, so you can't make the sum 1 with 2 dice.
0
If we put these in order, we get:
[tex]\frac{4}{5}[/tex], [tex]\frac{1}{2}[/tex], [tex]\frac{1}{6}[/tex], 0
So, the order going from top to bottom in the picture is: 2, 1, 3, 4

Answer:
10.51
Always look to the right of the place you are rounding
so...
if you look at 10.507140429
the 0 after 5 is in the hundredths place
look to the right of 0 and you'll see a 7.
If the number to the right of the place you are supposed to round to is:
5 or greater - round up
less than 5 - round down

Answer:
$12,155.06
Step-by-step explanation:
Using the compound interest formula;
A= P(1+r)^n
P = $10,000
rate r = 5% = 0.05
Time r = 4years
Substitute
A = 10,000(1+0.05)^4
A = 10,000(1.05)^4
A = 10,000(1.21550)
A = 12,155.06
Hence the amount after 4 years will be $12,155.06
Move the constant to the right.
