A school received 46 iPads. The school library took 26 of the iPads and the rest were split equally among 4 teachers to use in their
classrooms. Using the strip diagram and the letter x to represent the unknown quantity, which equation could be used to find the
number of iPads each teacher received?
A)
4x = 46 - 26
B)
4x +46 +26
4x - 26 - 46
D)
4x = 26 + 46
Answer:
Step-by-step explanation:
so what you need to do is subtracked 26 with 46 then you get the ansewer 20 but after that you have to do 20 divided by 4 and you will get your answer.
find and interpret the probability that exactly 13 of those surveyed feel the state of morals is poor
Complete question is;
In a recent poll, the Gallup Organization found that 45% of adult Americans believe that the overall state of moral values in the United States is poor. Suppose a survey of a random sample of 25 adult Americans is conducted in which they are asked to disclose their feelings on the overall state of moral values in the United States. Find and interpret the probability that exactly 13 of those surveyed feel the state of morals is poor.
Answer:
P(X = 13) = 0.1236 or 12.36%
This means that in 100 trials, approximately 12 of the trials should have exactly 13 of those surveyed feel the state of morals is poor
Step-by-step explanation:
We are given;
Sample size; n = 25
Chance of success; p = 45% = 0.45
This question is a binomial probability distribution problem and the formula is;
P(X = x) = nCx × p^(x) × (1 - p)^(n - x)
probability that exactly 13 of those surveyed feel the state of morals is poor is;
P(X = 13) = (25C13) × 0.45^(13) × (1 - 0.45)^(25 - 13)
P(X = 13) = 5200300 × 0.00003102864 × 0.00076621787
P(X = 13) = 0.1236 or 12.36%
This means that in 100 trials, approximately 12 of the trials should have exactly 13 of those surveyed feel the state of morals is poor

Answer:
90
Step-by-step explanation:
Because angles opposite congruent angles in a triangle are congruent, the triangle is isosceles.
The altitude drawn from the vertex angle of an isosceles triangle is the perpendicular bisector to the side it is drawn.
So, y=90.
Suppose that you 2 two dice and observe the numbers showing on the uppermost surfaces of the dice. What is the probability that the sum is less than 5
Answer:
The required probability (P) = 1/6
Step-by-step explanation:
From the given information:
Suppose two dice are observed; Then the number of outcomes in first dice = 6 i.e (1,2,3,4,5,6) and also the number of outcomes in second dice = 6 as well i.e (1,2,3,4,5,6)
The total number of outcomes of two dices = 6×6 = 36
Now for a sum that is less than 5; their outcomes are [(1,1) ,(1,2) , (1,3) ], [(2,1), (2,2) ], (3,1) = 6 outomes
The total number of outcomes for the sum that is less than 5 = 6
∴
The required probability (P) = Total number of outcomes for the sum that is less than 5 / Total number of outcomes of two dices
The required probability (P) = 6/36
The required probability (P) = 1/6
The probability that the sum is less than 5 is [tex]1\div 6[/tex].
Calculation of the probability:Since two dice are observed.
So the number of outcomes in first dice = 6 i.e (1,2,3,4,5,6) and also the number of outcomes in second dice = 6 as well i.e (1,2,3,4,5,6)
Now
The total number of outcomes of two dices = 6(6) = 36
Now for a sum that is less than 5; their results should be [(1,1) ,(1,2) , (1,3) ], [(2,1), (2,2) ], (3,1) = 6 outomes
So here the probability is
[tex]= 6/36\\\\= 1/6[/tex]

The area of a rectangular parking lot is 4947 m2.
If the length of the parking lot is 97 m, what is its width?
Width of the parking lot:
The perimeter of a rectangular pool is 304 m.
If the width of the pool is 68 m, what is its length?
Length of the pool:
Answer:
1. width = 51 m
2. length = 84 m
Step-by-step explanation:
So remember, the area is (length * width).
It is given that the length is 97, and the area is 4947.
So plug this into a formula:
length * width = area
97 * width = 4947
Solve using inverse operations;
97 * width = 4947
/97 /97
width = 51m
The perimeter of a rectangle can be found by doing, (2 * (length + width)).
The width is given, it is 68m. The perimeter is also given, 304m. So just form an equation using this information:
2 * ( length + width) = perimeter
2 * (length + 68 ) = 304
Distribute;
2 * ( length + 68) = 304
2 length + 136 = 304
Inverse operations;
2length + 136 = 304
-136 -136
2length = 168
/2 /2
length = 84m
Answer:
The answer for number 1 is width = 51 m
The answer for number 2 is length = 84 m

Answer:
The price ticket that we know is the adult ticket. The coupon shows that the ticket is good for $28.00. In the redd it shows that you save 4 dollars, so just add 4 to the 28 and the ORIGINAL price of the adult ticket is $32.00.
To find the price of the children's tickets, start with subtracting $28 (this is the price of the adult ticket) from the total of $76 (this is the total number of all the tickets combined).
76 - 28 = 48
Now divide that by 2
48/2 = 24$
So it was $24 per child

Stacy wants oil for the cake pops and cupcakes for her birthday party. She needs 1/2 of a cup of vegetable oil for the cake pops and 1.5 times as much oil for the cupcakes. If Stacy has 2 1/2 cups of vegetable oil, how much will she have left over after she makes the cake pops and cupcakes
Answer:
1 1/4
Step-by-step
The oil left over after she makes the cake pops and cupcakes is 1.25 cups.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, Stacy wants oil for the cake pops and cupcakes for her birthday party.
She needs 1/2=0.5 of a cup of vegetable oil for the cake pops and 1.5 times as much oil for the cupcakes.
So, oil required to make cupcakes is 1.5 ×1/2
= 1.5/2
= 0.75
Stacy has [tex]2\frac{1}{2}[/tex] =2.5 cups of vegetable oil
Total vegetable oil used =0.75+0.5
= 1.25 cups
Oil left over is 2.5-1.25=1.25
Therefore, the oil left over after she makes the cake pops and cupcakes is 1.25 cups.

PLEASE HELP , DUE IN AN HOUR !!! Suppose a friend tells you she paid a total of $8,540 for a motorcycle, and you'd like to know the motorcycle's list price (the price
before taxes) so that you can compare prices at various dealers. Find the list price,p, of the motorcycle if your friend bought the
motorcycle in:
a) Washington, where the sales tax is 6.5%.
b) Idaho, where the sales tax is 6.0%.
C) A state where the sales tax is r. Assumer is in decimal format.
d) Solve for r in your answer to (c) above
Answer:
a) $8018.78
b) $8056.60
c) 8540 / (1+r)
d) r = (8540/x) - 1 where "x" is the list price.
Step-by-step explanation:
Recall that the:
total price paid = list price + sales tax
total price paid = list price + percent * list price
a) then, in Washington:
8540 = x + 0.065 * x
8540 = x (1 + 0.065)
8540 = x (1.065)
x = 8540 / 1.065
x = $8018.78
b) in Idaho where the sales tax is 6.0% we do a similar calculation but using the decimal form of the percent 0.06:
8540 = x (1 + 0.06)
8540 = x (1.06)
x = 8540 / 1.06
x = $8056.60
c) If the percent tax is "r" then:
we do:
8540 = x (1+r)
x = 8540 / (1+r)
d) solving for "r" instead of for "x":
8540 = x (1+r)
divide by "x" (the list price):
(8540/x) = 1 + r
subtract 1 from both sides:
(8540/x) - 1 = r
