Answer:
A
Step-by-step explanation:
While the obvious answer might be Book B because that had the most amount of teachers that approved it, I looked at it a different way. I think that the best book has the greatest percentage of teachers approved compared to the total teachers who reviewed the book. Let's apply this to the 4 books.
A: Approved = 8 Total = 9 8/9 = 88%
B: Approved = 24 Total = 29 24/29 = 83%
C: Approved = 12 Total = 16 12/16 = 75%
D: Approved = 20 Total = 26 20/26 = 77%
As you can see, Book A should be chosen because it has the highest percentage. I hope this helps and makes sense!

In a class 27 of students, 12 have a cat and 11 have a dog. There are 5 students who have a cat and a dog. What is the probability that a student has a dog given that they have a cat?
Answer:
41.67% probability that a student has a dog given that they have a cat
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: having a cat.
Event B: having a dog.
12 of 27 students have a cat:
This means that [tex]P(A) = \frac{12}{27}[/tex]
5 students who have a cat and a dog.
This means that [tex]P(A \cap B) = \frac{5}{27}[/tex]
What is the probability that a student has a dog given that they have a cat?
[tex]P(B|A) = \frac{\frac{5}{27}}{\frac{12}{27}} = \frac{5}{12} = 0.4167[/tex]
41.67% probability that a student has a dog given that they have a cat

An ice cream parlor donated 6 containers of ice cream to a local elementary school. Each container holds 3 gallons of ice cream. If each student is served 1 cup of ice cream, how many students can be served?
Answer:
288 students can be served
Step-by-step explanation:
Looking at the donation made by the ice cream parlor, we want to know the number of students to be served.
We need to achieve a consistency in units first. What I mean by this is that all our units must be the same.
The parlor donated 6 containers with each container holding 3 gallons. The amount donated is thus 3 * 6 = 18 gallons of ice cream
Mathematically, there are 16 cups in a gallon. Thus, the amount of cups donated by the parlor would be 16 * 18 = 288 cups
Now since 1 student takes 1 cup of ice cream, the number of students that the donation can serve is 288/1 = 288 students

Which of the following questions are statistical questions? (more than one and assume the question is asked of the entire class)
A
How many dogs do you own?
B
How tall is Mrs. Zieroff?
C
What did you eat for dinner?
D
What were the ingredients in last nights soup?
E
How far did each paper airplane travel?
Answer:
A,C,E
Step-by-step explanation:
A statistical question has variability in the answer, so,
A=could range from any numbers providing a wide range of results
B=it's one answer (eg.5ft4) meaning a range can't be produced
C=could range from any food providing a wide range of results
D=One answer so no variations possible
E= could be a range of numbers

Solve the system of linear equations by substitution.
y=−4x−9
4x−y=1
Answer:
x=-1, y=-5 ---> (-1, -5)
Step-by-step explanation:
so you want to plug one equation into the other. so start off by plugging y=−4x−9 into the y value of 4x−y=1-----> 4x-(-4x-9)=1. now subtract and isolate x which ends up being x=-1. now plug the x=-1 into either equation and isolate and solve for your y value which ends up being y=-5. you can check you answer by plugging both the x and y you found into one equation and making sure the answer it gives is true. ;)
The solution for equations y=-4x-9 and y=-4x-9 is x=-1, y=-5.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equations are,
y=-4x-9 (1)
4x-y=1 (2)
From equation (1), substitute the value of y in equation (2)
4x-(-4x-9)=1
8x+9=1
8x=-8
x=-1
Substitute x=-1 in equation (1),
y=-4(-1)-9
y=4-9
y=-5
The value of x is -1 and y is -5

Find the unit rate.
48 cupcakes in 6 boxes=cupcakes per box
Answer:
[tex]\frac{8 cupcakes}{1 box}[/tex]
Step-by-step explanation:
All we have to do for this problem is divide.
48 / 6 = 8
There are 8 cupcakes per box.
Answer: 8 cupcakes per box
Step-by-step explanation: "Per box" means in 1 box, so we can rewrite the given statement using fractions as
48 cupcakes/6 boxes = __ cupcakes/1 box.
To find out what goes in the blank, notice that we
have a 1 in the denominator of our second fraction.
So we want to find a fraction that is equivalent
to 48/6 that has a 1 in the denominator.
If we divide the numerator and denominator of 48/6 by 6,
we get the equivalent fraction 8/1 or 8 cupcakes/1 box.
So now we have 8 cupcakes/1 box = __cupcakes/1 box.
So an 8 must go in the blank which means that the unit rate
for 48 cupcakes in 6 boxes is 8 cupcakes per box.
Bonnie had 5 cats that each weighed 6 2/5 pounds. How much do the cats weigh?
32 pounds because 6.4x 5=32.
Devon purchased one bag of dog food and three bags of cat food. Each bag of dog food weighs x pounds and each bag of cat food weighs half as much as the bag of dog food. The total weight of Devon's purchase is 32.5 pounds. The equation x+3(x/2)=32.5 can be used to determine the weight of the dog food and cat food. What is the weight in pounds of one bag of cat food?
Answer:
A pound of cat food will weigh 6.5 pounds
Step-by-step explanation:
Firstly, we need to get the value of x. Thus, let’s solve the equation at hand;
x + 3x/2 = 32.5
x + 1.5x = 32.5
2.5x = 32.5
x = 32.5/2.5
x = 13
Now from the question, we are made to know that a pound of cat food measures half of what a pound of dog food measures
Since we calculate a pound of dog food to weigh 13 pounds, a pound of cat food will weigh = 13/2 = 6.5 pounds

ABC is an isoscles triangle. Angle A = 40°.
Find measure of Angle B.
40
70
75
180
Answer:
70 degrees
Step-by-step explanation:
total angle in a triangle is 180 degrees
180-40= 140
Angle b and c is total of 140 degrees
they are isosceles so their measurements would be same.
angle b and c is 140÷ 2 = 70
so angle b is 70 degrees

Step 1) Divide the figure into shapes
Large rectangle: 5 x 12
Smaller rectangle: 4 x 6
Square: 2 x 2
Triangle: 4 x 3
Step 2) Find the area of each shapes
Large rectangle: A = 5 x 12 = 60
Smaller rectangle: A = 4 x 6 = 24
Square: A = 2 x 2 = 4
Triangle: A = 1/2 x 4 x 3 = 6
Step 3) Add all of the areas together
A = 60 + 24 + 4 + 6 = 94 square miles

I’m doing work that if I miss one I have to start over. Having lots of issue passing this
Answer:
0.25
Step-by-step explanation:
Probability is the chance you get a certain thing when you pick randomly. In this case, it's asking the probablility of picking someone from a whole student survey that does music or drama.
Looking at the two way table is easy! Out of all grades, 65 are in sports, 25 have music or drama, and 10 has work. Add them all up and get 100.
However, we only found the people in the survey. We need to find the probability of someone in music and drama. So we divide the number of people in all grades who take that class and divide it by the total amount- 25/100, this turns out for the probability to be 0.25.

The square of 2.8 is 78.4
(step by step explanation)
answer fastly
The answer is false.
The square of 2.8 is actually 7.83999 or 7.84 if rounded.
To get this, we simply bring 2.8 to the power of 2.
2.8 x 2.8 = 7.8399
Therefore, the answer would be false since the actual square of 2.8 is 7.84

How to expand the following problem
PLEASE HELP which equation in the word bank can solve for x ?
Answer:
x + 10 = 24
Step-by-step explanation:
In the figure attached,
There are two external points A and B.
Fro point A two tangents AD and AE have been drawn and From point B tangents BE and BC have been drawn.
Since AD = 10 units,
Therefore, AE = 10 units
(Since tangents drawn from a point to a circle are same in measure, therefore, AD = AE)
Therefore,
BE = AB - AE
Since BE = BC
So BC = AB - AE
x = 24 - 10
x + 10 = 24
Therefore, (x + 10) = 24 will be the equation to be used to solve for x.

You pick a card at random. Without putting the first card back, you pick a second card at random.
What is the probability of picking a 3 and then picking a 3?
Simplify your answer and write it as a fraction or whole number.
Answer:
The answer could be 0 or 1 out of 4, because choosing a card at first and not putting it back, then picking a second card at random, it would likely be one in zero attempts to pick 3 again but otherwise that it could be 1 out of 4 because it could be possible picking 3 at the first try.
