The farmer's market sells fruit baskets.
✔ Each basket contains 12 apples and 4 pears. ✔ Use a to represent the cost of each apple and p for the cost of each pear.
1. Write an EXPRESSION that represents the cost of 12 apples
2. Write an EXPRESSION that represents the cost of 4 pears
3. Write an EXPRESSION that represents the TOTAL COST of one basket
Answer:
Let a be the cost of each apple.
Let p be the cost of each pear.
Q1
Cost of 12 apples = 12a
Q2
Cost of 4 pears = 4p

Step-by-step explanation:
Got it right on edge
Answer:
Step-by-step explanation:
The 12th percentile is found on the LEFT of the graph since it is 0.12.
Since it’s on the left, the percentage will be NEGATIVE.
The z-score is -1.175
ITS RIGHT ON EDGE.

Brayden and Aubrey are both driving along the same highway in two different cars to a stadium in a distant city. At noon, Brayden is 280 miles away from the stadium and Aubrey is 340 miles away from the stadium. Brayden is driving along the highway at a speed of 30 miles per hour and Aubrey is driving at speed of 40 miles per hour. Let
B
B represent Brayden's distance, in miles, away from the stadium

the number p, if 1/3 of p is 16
Answer:
48
Step-by-step explanation:
1/3 p = 16.
16 x 3 = p
p = 48
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The value of p is 48.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
1/3 of p is 16.
This can be written as,
1/3 x p = 16
Multiply 3 on both sides.
p = 3 x 16
p = 48
Thus,
The value of p is 48.

-x2 - 4x + 21
Factorise
9514 1404 393
Answer:
-(x -3)(x +7)
Step-by-step explanation:
Apparently, you're supposed to match the given expression with the parts of the identity ...
(x + a)(x + b) = x² +(a +b) +ab
First of all, we notice that the sign of x² in our given expression is negative. So, we factor -1 out of the expression first.
-x² -4x +21 = -(x² +4x -21)
Now, matching the coefficients of x, and the constant to those in our identity, we see ...
a + b = 4 . . . . . coefficients of x
ab = -21 . . . . . . constants
It is relatively easy to find the factors of -21. We are interested in those factor pairs such that the sum is positive:
-21 = -1(21) = -3(7) = -7(3) . . . . at this point the sum -7+3 becomes negative
The factor pair a=-3, b=7 will satisfy ...
a + b = -3 + 7 = 4
ab = (-3)(7) = -21
So, our factorization is ...
-x² -4x +21 = -(x² +4x -21) = -(x -3)(x +7)

It is known that the amount of beer poured by this filling machine follows a normal distribution with a mean of 12.14 ounces and a standard deviation of 0.06 ounce. a) Find the probability that the bottle contains fewer than 12.00 ounces of beer. Label the sketch of the normal curve with the values from the problem situation. Label the mean and the desired outcome. Use a z-score to find the probability. Round your answer to 2 decimal places. b) Now that you have a probability that a bottle contains less than 12 ounces, what would be the probability that at least one bottle in a six pack would contain less than 12 ounces. Recall the probability of at least one from section 5-3, and a binomial distribution. c) The brewery is concerned about the probability of a customer getting a bottle with less than 12 ounces. What could the brewery do that would lower the chance that a customer would get a bottle with less than 12 ounces?
