There are three colors of jellybeans in a jar: Red, orange, and yellow. On a random pick, the probability of getting a red jellybean is 1/8 and the probability of getting an orange jellybean is 1/4. What is the probability of getting a yellow jellybean?
Answer: 5/8
Step-by-step explanation:
Probability of getting a red jellybean = 1/8
Probability of getting an orange jellybean = 1/4
Probability of getting a yellow jellybean = 1 - (⅛ + ¼)
= 1 - (1/8 + 2/8)
= 1 - 3/8
= 5/8
Therefore, the probability of getting a yellow jellybean is 5/8

The formula for the volume of a pyramid is
V=1/3bh
Which equation solves the formula for h
Answer choices:
F: h=3Vb
G: h=3b/V
H: h=3V/b
J: h=V/3b
Answer:
h = 3v/b
Step-by-step explanation:
Here, we want to select the equation that solves for h
What this simply means is that we should make h the subject of the formula
Thus, we have 3 * v = bh
3v = bh
h = 3v/b

80% of the tickets sold at a water park were child tickets. If the park sold 720 tickets in all, how many child tickets did it sell?
Answer:
576 child tickets were sold.
Step-by-step explanation:
Since you know the amount of tickets that were sold and the percentage of the tickets that were child tickets, you have to multiply the number of tickets sold by that percentage to find the answer:
720*80%= 576
According to this, the answer is that 576 child tickets were sold.

Calculate the expected value of playing a lottery ticket game where each ticket costs $5, and the chance of having winning ticket is one in one million, and the payout for having a winning ticket is 4.9 billion dollars. Round the expected value to the nearest cent.
Answer:
$4895
Step-by-step explanation:
P(winning) = 1 / 1000000 = 0.000001
P(not winning) = 1 - 1/1000000 = 0.999999
Winning amount = 4,900,000,000 - 5 = 4899999995
Amount lost = - 5
__ X: - 5 _________ 4899999995
P(X) : 0.999999 ___ 0.000001
Expected value E(x) = Σx * p(x)
E(x) = - 5(0.999999) + 4899999995(0.000001)
E(x) = - 4.999995 + 4899.999995
E(x) = 4895
Hence, expected value is 4895

(Choice C)

D

E

Answer:
B. -7 is less than or equal to x, which is less than 12
Step-by-step explanation:
-7x -50 </= -1
add 50 to both sides
-7x <= 49
divide both sides by -7. When you divide and inequality by a negative number, the direction of the inequality changes.
x >/= -7
---------------------------------
-6x + 70 > -2
subtract 70 from both sides
-6x > -72
divide both sides by -6, flipping the inequality sign
x < 12
------------------------------
Since the problem says *and*, we can say x is equal than or greater to -7 and less than 12
-7 </= x < 12
please let me know if you have questions, or if the signs don't come through clearly

If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right.
longest side = 30 , then 30² = 900
20² + 23² = 400 + 529 = 929 ≠ 900
Then the triangle is not right.

Answer:

Step-by-step explanation:
Since this is a multiple choice question, I will employ the guess and check method - meaning I will check each answer one by one.
Variable x = dimes = $0.10
Variable y = quarters = $0.25
Set up a system of equations:
x + y = 38
x(0.10) + y(0.25) = 6.80
Plug in each choice into the second equation. You can find the number of quarters that correspond to each number of dimes by using the first equation.
20 dimes:
20 + y = 38
y = 18
20(0.10) + 18(0.25) = 6.80
2 + 4.5 = 6.80
6.5 does not equal 6.80
Because dimes (x) are worth less than quarters (y), this result tells us the answer will be less than 20 dimes as with 20 or more we have less than $6.80. Another example just to show this is true:
38 dimes:
38 + y = 38
y = 0
38(0.10) + 0(0.25) = 6.80
3.8 + 0 = 6.80
3.8 does not equal 6.80.
Since x is worth less than y, we need more of y rather than x. Adding more x will only mean we will get a lower price. Adding more y will mean we get a higher price which is what we need. So only solve for x that is less than 20.
6
6 + y = 38
y = 22
6(0.10) + 32(0.25) = 6.80
0.60 + 8 = 8.60
8.60 does not equal 6.80.
This result is higher than what we wanted (6.80) which means we need more x. Now we only have to solve for x numbers that are greater than 6 and less than 20.
18
18 + y = 38
y = 20
18(0.10) + 20(0.25) = 6.80
1.8 + 5 = 6.8
6.8 does equal 6.8.
Correct!

Answer:
420 cubic inches. Or 420 inches cubed
Step-by-step explanation:
V = l * w * h
12 * 7 * 5 = 420
Answer:
7*5*12= 420
Step-by-step explanation:
Volume of a rectangular prism would be Length * width * height.
so the length = 12 inches
the width = 5 inches
and the height = 7 inches
Plug those in and you get 420 inches cubed :)

HELP 5TH GRADE MATH EASY
Answer:
the area is 24 (8 x 3)
and the perimeter is 22 (8 + 8 + 3 + 3)
Step-by-step explanation:
Answer:
Area: 24
Perimeter: 22
Step-by-step explanation:
To solve the area, the equation is l*w, or in this case 3*8, which is 24.
To solve the perimeter, the equation is 2l + 2w, or in this case (3*2)+(8*2).
An archaeologist divides an area using a coordinate plane in which the coordinates are measured in meters. The vertices of a secret chamber are (-4,-1), (2,-1) , (2,5) , and (-4,5) . Find the perimeter and the area of the secret chamber.
Answer:
Perimeter = 24 units
Area = 36 square units
Step-by-step explanation:
An archaeologist divides an area using a coordinate plane in which the coordinates are measured in meters. The vertices of a secret chamber are (-4,-1), (2,-1) , (2,5) , and (-4,5) . Find the perimeter and the area of the secret chamber.
We have to find the length of the sides of the rectangle using the formula below
= √(x2 - x1)² + (y2 - y1)² when given vertices (x1, y1) and (x2, y2)
For sides A
(-4,-1), (2,-1)
= √(2 - (-4))² + (-1 -(-1))²
= √(2 + 4)² + (0)²
= √6²
= √36
= 6 units
Side B
(2, -1), (2,5)
= √(2 - 2)² + (5 - (-1))²
= √0² + (5 + 1)²
= √0 + 6²
= √36
= 6 units
For side C
(2,5) , and (-4,5)
= √(2 - (-4))² + (5 - 5)²
= √6² + 0²
= √36
= 6 units
For side d
(-4,-1), (-4,5)
= √(-4 - (-4))² + (5 - (-1))²
= √(-4 +4)² + (5 + 1)²
= √0 + 6²
= √36
= 6 units
From the above calculation, all the sides of the secret chamber are equal to one another
Side a = Side b = Side c = Side d
This means the chamber is has the shape of a square.
The perimeter of the secret chamber =
P = 4a
a = Length of one side = 6 units
P = 4 × 6 units
P = 24 units
The area of the secret chamber
A = a²
a = Length of one side = 6 units
A = ( 6 units)²
P = 36 square units
