Step-by-step explanation:
Suppose pieces of chocolate pie served at a restaurant average 350 calories with a standard deviation of 20 calories. Calories have a Normal distribution due to inexact cutting of the pies. Which graph represents the proportion of pieces of pie that have more than 375 calories.
Answer: The z score is used to determine how many standard deviations that the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and for a negative z score means the raw score is below the mean. The z score is given as:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
Given that: μ = 350 calories, σ = 20 calories, x > 375
[tex]z=\frac{x-\mu}{\sigma}\\\\z=\frac{375-350}{20}=1.25[/tex]
From the graph, The shaded area represents the proportion of pieces of pie that have more than 375 calories
From the normal distribution table, P(x > 375) = P(z > 1.25) = 1 - P(z < 1.25)
= 1 - 0.8944 = 0.1056 = 10.56%

Maisie has saved up $50 to buy concert tickets, but the tickets cost $125. She is able to earn $15 per day by walking her neighbor’s dogs. How many days will Maisie have to walk the dogs to earn enough money to buy the tickets? Let d = the number of days worked.
Subtract 50 from 125
75
Divide by 15 (number of dollars per day)
5
If Maisie walks her neighbors dogs for 5 days, she will save up to a total of 125

Why is the answer for letter b 9?
Answer:
Take a look at the 'proof' below
Step-by-step explanation:
The graph of the function g(x) is similar to that of the function f(t). The local minimum, local maximum, absolute minimum, maximum etc... of 'x' is always the closest x-intercept of the graph of f(t).
Let's check if this statement is right. The two local minimum(s) of the function f(t) occurs at x = 2, and x = 6. The two local maximum(s) occur at 1/4 and 4. As you can see the maximum / minimum of the function g(x) is always an x-intercept, x = 3, x = 7.
For part (b) the absolute maximum value of the function f(t), is 8. The closest x-intercept is 9, which is our solution.
Step-by-step explanation:
From x=0 to x=1, the function is above the x-axis, so the area is positive.
From x=1 to x=5, the area above the x-axis is greater than the area below the x-axis, so the net area is positive.
From x=5 to x=9, the area above the x-axis is greater than the area below the x-axis, so the net area is positive.
Since the area increases in each interval, the area is a maximum at x=9.
A bag contains 26 tiles, each with a different letter of the alphabet written on it. You choose 3 tiles from the bag without looking. What is the probability that you chose tiles with the letters A,B,C?
Ps: don’t text me only if u know the answer that’s it
Answer:
for each letter 1 /26 is the probability
Step-by-step explanation:
probability = no. of events / no. of outcome
probability for tile A
= no. of events / no. of outcome
= 1 / 26
probability for tile B
= no. of events / no. of outcome
= 1 / 26
probability for tile C
= no. of events / no. of outcome
= 1 / 26

A. 3÷81
B. 27
C. 81÷3
D.81×3
Answer:
C. 81÷3
Step-by-step explanation:
We want to write a numerical expression for the phrase: "the quotient of 81 and 3"
Quotient indicates division, so we must divide 81 by 3.
81÷3
This can be further simplified, but the questions asks for a numerical expression. This is defined as an expression with numbers and at least one operation. So, B is correct, because 81 divided by 3 is 27, but it is not a numerical expression.
Therefore, the best answer choice is C. 81÷3
A faucet leaks water at a constant rate of 58 quart every 15 minutes.How many quarts does the faucet leak per hour?

Kaleb can skateboard 75 feet in 25 seconds. How far can he skateboard in 3.25 minutes?
Answer:
585 Feet
Step-by-step explanation:
First, you have to consider how much seconds in a minute. 60.
Then, multiply 75 feet to make it match to 60 seconds. So 60/25. You get 2.4. You multiply 2.4 by 75 to get 180 feet per minute.
Finally, you multiply 180 by 3.25, as it is 3.25 minutes.

Simplify using order of operations. Show all of your work and do ONE operation at a time to receive all possible points. 90 ÷ [ 10 + ( 3 2 − 4 ) ]
An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression when simplified is equal to 2.3684.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
As per the PEMDAS, we will first solve the parenthesis. Since the round parenthesis is solved first, therefore, we can write,
90 ÷ [10 + ( 32 − 4 )]
= 90 ÷ [10 + (28)]
= 90 ÷ [10 + 28]
Solving the next parenthesis, therefore, the square brackets,
= 90 ÷ [10 + 28]
= 90 ÷ 38
At last, we will solve the division, therefore, we can write,
= 90 ÷ 38
= 2.3684
Hence, the value of the expression when simplified is equal to 2.3684.

Omar's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs $4.10 Omar per pound, and type B coffee costs $5.30 per pound. This month, Omar made 141 pounds of the blend, for a total cost of $640.50. How many pounds of type A coffee did he use?
Hey there! I'm happy to help!
Let's use the variables A and B to represent the number of pounds used of types A and B.
4.10A+5.30B=640.50
A+B=141
Let's rearrange the bottom equation to solve for B.
A+B=141
Subtract A from both sides.
B=141-A
We can put this value of B into the first equation to solve for the number of pounds of type A Omar used.
4.10A+5.30(141-A)=640.5
We use distributive property to undo parentheses.
4.10A+747.3-5.3A=640.5
We combine like terms.
-1.2A+747.3=640.5
Subtract 747.3 from both sides.
-1.2A=-106.8
Divide both sides by -1.2
A=89
Omar used 89 pounds of type A coffee in this month's blend.
