Answer:
B and C
Step-by-step explanation:
A general way to know this is, if the answer can be given as a rate, percentage, or probability, then this is a statistical question
If the answer is yes, no, true, false, or something exact, then the question is not statistical.
Let's analyze the given questions:
a) "How many cups are in a gallon?"
There is an exact number of cups in a gallon (16) so this is not an staistical question.
b) "Which measure spoon do home backers use most frequently?"
While here the answer may be something like "teaspoon", the root of the answer is a percentage, here we actually would see the percent of home backers (so we need to find a sample, study that sample, etc) that use each spoon, and based on that, we could conclude what is the correct answer, then this is a statistical question.
c) "On average, how much salt do professional pastry chefs use in pie crust?"
Here we need to find a mean value, so we would need to do a survey and etc, then this is a statistical question.
d) "Which is larger, 17 ounces or 2 cups?"
Here we have an exact solution, so this is not a statistical question.
e) "Did a specific store sell more measuring cups or measuring spoons on a given day?"
Here we just need to compare the two numbers:
number of measuring cups sold = k
number of measuring spoons sold = m
And we need to see which one is larger, so the answer is exact, thus, this is not a statistical question.
This may be similar to option B, the difference is that in option B we are talking about all home backers, so we need to find a sample and do statistics, while in this case, we are talking about a specific store.
Then the correct options are: B and C

136 yhdiby8sruygftdtuggdyubhAnswer:
Weight of each large box: 18.25kg
Weight of each small box: 13.25kg
Step-by-step explanation:
For this question, we have two unknowns, but we can solve them as we are given two equations.
If we use the variables 'L' for Large and 'S' for small, we an write out the information given to us as equations:
3L + 5S = 121
6L + 2S = 136
Now we can solve these simultaneous equations by multiplying one of them by a constant so that one of the variable co-efficients are the same so we can cancel them. We can see here that we can easily double the first equation which would result in both having 6L:
2(3L + 5S) = 2(121)
=> 6L+10S=242
Now that we have one term which is the same, we can subtract one equation from the other:
6L+ 10S = 242
- (6L + 2S = 136)
------------------------
=>0L + 8S = 106
Now we can solve for S:
8S/8 = 106/8
S = 13.25
And use this value of S to solve for L:
3L + 5(13.25) = 121
3L + 66.25 = 121
3L + 66.25 - 66.25 = 121 - 66.25
3L = 54.75
3L/3 = 54.75/3
L = 18.25

I need help please you haft to use elimination to solve thanks
Answers
-3x+7y=-3
when using elimination you need to multiply or divide one equation to be able to “eliminate” a variable.
-7x+14y=-14
-2(-3x+7y=-13)
multiply the second equation by -2
-7x+14y=-14
6x-14y=6
simplify
-1x=-8
divide by -1 on both sides to isolate the x
x=8
now you can plug in 8 for x in one of the equations.
-3(8)+7y=-3
simplify
-24+7y=-3
add -24 to both sides the isolate the constant and variable
7y=21
now divide by 7 on both sides to isolate y
y=3
this system of equation had one solution at (8, 3)

Find the roots of f(x)=x2+9x-36.
x = _____ or x = _____
Answers
Hi there!
[tex]\large\boxed{x = -12, 3}[/tex]
The roots of a function are when f(x) = 0, so:
0 = x² + 9x - 36
Find two numbers that multiply to -36 and add up to 9.
We get the numbers 12 and -3, so:
0 = (x + 12)(x - 3)
Set each equal to 0 to find the x value:
0 = x + 12
x = -12
0 = x - 3
x = 3

Answers
Step-by-step explanation:
We are going to start by working out the interior angles so first of all to work out the interior angle we used the formula: num of sides - 2 * 180 for the sum of degrees in a shape.
Lets test this formula.
Lets say we have a square it has 4 sides 4-2 = 2 *180 = 360 this is correct,meaning we can trust this formula.
Now lets put it to use.
Octagon has 8 sides - 2 = 6.
6 * 180 = 1080
Pentagon has 5 sides - 2 = 3
3 * 180 = 540
Another Pentagon 5 sides - 2 = 3
3 * 180 = 540
We have to find out a single angle because it is one side that joins to the other, also if it is a perfect fit then all the single angles must add up to 360.
1080/8 sides = 135 degrees
540 / 5 sides = 108 degrees
540 / 5 sides = 108 degrees
We add these up,
135 + 108 + 108 = 351 which cannot be a possible fit because we need 360 degrees.

The front row in a movie theatre has 23 seats. If you were asked to sit in the seat that occupied the median position, in which seat would you have to sit?
Answers
Answer:
12
Step-by-step explanation:
The median is the one in the middle. For an odd number of seats, average the first and last seat numbers.
(1 + 23) / 2 = 24 / 2 = 12. That means there will be 11 people on your left and 11 people on your right.
For an even number of seats, the same method doesn't work as well! If there are 14 seats, for example, (1 + 14) / 2 = 15 / 2 = 7.5, and if you sit in "seat" 7 and a half, it will be awkward!

If the base of a triangle is 3 and its
height is 4, then its area is 6. This
triangle has an area of 6, so its
base is 3 and its height is 4.
Answers
Step-by-step explanation:
the area of a triangle is base times height divided by 2.
A = (b × h) / 2
so, when b = 3 and h = 4, then
A = (3 × 4) / 2 = 12 / 2 = 6
correct.
now the other way around
we know the area (6).
=> 6 = (b × h) / 2
=> 12 = b × h
well, b=3, h=4 is one possible solution for this.
but so is e.g. b=2, h=6, or b=12, h=1, or ...
and that is just the natural numbers. then there are rational numbers and so on.
therefore there is an infinite set of possible (b, h) pairs that satisfy the equation 12 = b × h.
therefore the statement that we can conclude out of a given triangle area of 6 that b must be then 3 and h must be 4 is wrong.
simple - it is one equation with 2 variables and has therefore usually not just one solution.

A grocery store is reevaluating the retail price of their oranges. They have a contract where they can purchase oranges for $0.52 per pound. However, this includes high quality oranges (about 40% of the time), low quality oranges (55%), and occasionally rotten fruit (5%). Suppose they sell 80% of all high quality oranges at $1.99 per pound, 65% of all low quality oranges at $1.49 per pound (they offer a sale), and they cannot sell any of the rotten fruit. What is the store's expected profit from a random shipment of 500 pounds of oranges

The store's expected profit from a random shipment of 500 pounds of oranges is approximately $400.88.
Here, we have,
To calculate the store's expected profit from a random shipment of 500 pounds of oranges, we need to consider the probabilities and prices associated with each quality category of oranges.
Let's break down the calculations step by step:
High Quality Oranges:
Probability: 40% of the time
Purchase price: $0.52 per pound
Selling price: $1.99 per pound
Expected profit per pound: $1.99 - $0.52 = $1.47
The expected profit from high-quality oranges per pound is $1.47.
To calculate the expected profit from high-quality oranges in the entire shipment, we multiply the expected profit per pound by the total weight of high-quality oranges:
Expected profit from high-quality oranges = 0.4 * $1.47 * (0.8 * 500) = $235.20
Low Quality Oranges:
Probability: 55% of the time
Purchase price: $0.52 per pound
Selling price: $1.49 per pound
Expected profit per pound: $1.49 - $0.52 = $0.97
The expected profit from low-quality oranges per pound is $0.97.
To calculate the expected profit from low-quality oranges in the entire shipment, we multiply the expected profit per pound by the total weight of low-quality oranges:
Expected profit from low-quality oranges = 0.55 * $0.97 * (0.65 * 500) = $165.68
Rotten Fruit:
Probability: 5% of the time
The store cannot sell any rotten fruit, so the expected profit from rotten fruit is $0.
Now, let's calculate the total expected profit from the entire shipment of oranges:
Total expected profit = Expected profit from high-quality oranges + Expected profit from low-quality oranges + Expected profit from rotten fruit
= $235.20 + $165.68 + $0
= $400.88
Therefore, the store's expected profit from a random shipment of 500 pounds of oranges is approximately $400.88.

[tex]CosB=\frac{3}{5}[/tex]
Let X be the adjective side to A
Let Y be the opposite side to B
Generally the equation for X is mathematically given by
[tex]X^2=\sqrt{53^2-28^2}[/tex]
[tex]X=45[/tex]
Therefore [tex]TanA[/tex]
[tex]TanA=\frac{28}{45}[/tex]

How do I solve these problems?
Answers
Answer:
- 32, - 7, 18 and 127, 106, 85
Step-by-step explanation:
Add the common difference d to the previous term
(1)
a₁ = - 32
a₂ = a₁ + 25 = - 32 + 25 = - 7
a₃ = a₂ + 25 = - 7 + 25 = 18
The first 3 terms are - 32, - 7, 18
(2)
a₁ = 127
a₂ = a₁ + d = 127 - 21 = 106
a₃ = a₂ + d = 106 - 21 = 85
The first 3 terms are 127, 106, 85
Answer:
-32, -7, 18 and
127, 106, 85
Step-by-step explanation:
You can use the following formula to solve this:
[tex]a_{n} = a_{1} + (n - 1)d[/tex]
a is the nth term in the sequence. So at the 3rd term, n = 3
a₁ is the first term in the sequence. In your first question, a₁ is -32. In your second, a₁ is 127.
(n - 1) represents the term before a, or the term before the current term. So at the 3rd term, (n - 1) = 3-1, which is 2.
d represents the common difference between terms. Aka what you add or subtract to a term to get the next one.
For the first question, you know a₁ and d, so you can substitute them into the equation to find the second and third terms:
a = -32 + (n - 1)25
You also know (n-1), because a is 2 when you're looking for the second term. So (n-1) = 2-1, which is 1. So put that in the formula and simplify:
a = -32 + (1)25
a = -32 + 25
a = -7
The second term is -7. To find the 3rd term, do the same thing.
a = -32 + (n - 1)25
(n-1) is 2, since you're on the third term and n is 3.
a = -32 + (2)25
a = -32 + 50
a = 18
So the first 3 terms are -32, -7, and 18.
For the second one, the formula looks like this:
a = 127 + (n - 1)-21
The first term is 127. Find the 2nd (n is 2):
a = 127 + (1)-21
a = 127 -21
a = 106
Then find the 3rd term (n is 3)
a = 127 + (2)-21
a = 127 -42
a = 85
So the first 3 terms are 127, 106, and 85.
