This is a system of equations problem:
Part one set up general equations
1) Peanuts = 3x ($3 per pound)
2) Jellybean = 1.5y ($1.50 per pound)
Relate x and y to the information you have
He wants 30lb. total: x + y = 30
He also wants the mixture to be valued at $2.50 per pound = 3x + 1.5y = 30(2.5)
*I'm taking $2.50 times 30 because you want the total cost to equal since he wants $2.50 per pound.
You want to substitute one equation into the other.
x + y = 30
3x + 1.5y = 75
1) x + y = 30 => x = 30 - y
2) 3(30 - y) + 1.5y = 75
3) 90 - 3y + 1.5y = 75
4) -1.5y = -15
5) y = 10lb.
Then plug that into one of the original equations to get x.
6) x+ y = 30 => 10 + x = 30 => x = 20lb.
He wants 20lb. of peanuts and 10lb. of jellybeans
Answer:
c=1
Step-by-step explanation:
Answer:
Option a is correct.
Step-by-step explanation:
Since both fiber and sugar are types of carbohydrates and it is given that a portion of food has 24 gm of total carbohydrate and within which 2 gm of fiber and 12 gm of sugar.
Therefore, this food contains 2 g of fiber, 12 g of sugars, and 10 g of other unnamed carbohydrates, for a total of 24 g.
Hence, option (a) is correct. (Answer)
Considering the given data-set, we have that:
- The lowest batting average is of 0.254.
- On the histogram, 5 values would fall into the class 0.251 - 0.280.
<h3>What is an histogram?</h3>
An histogram is a graph that shows the number of times each element of x was observed, or the number of elements x in a range of values, as is used for this problem.
For the given 20 batting averages given in the table, we have that:
- Looking at all of them, the lowest value of the table is of 0.254, hence the lowest batting average is of 0.254.
- The measures in the table between 0.251 and 0.28 are: 0.277, 0.265, 0.267, 0.259, 0.254. Hence, this means that on the histogram, 5 values would fall into the class 0.251 - 0.280.
