Wren is at the grocery store buying fruit. She buys x pounds of apples for $1.68 per pound. She buys 2 fewer pounds of grapes for $2.48 per pound. The cost of the fruit, before tax, is $13.76. How many pounds of each fruit is she buying?
Answer:
The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5
Step-by-step explanation:
Let
x ------> the number of pounds of apples
(x-2) -----> the number of pounds of grapes
we know that
Solve for x
so
therefore
The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5
Answer:
4.5 pounds of apples
2.5 pounds of grapes
Step-by-step explanation:
a = # of apples
(a - 2) = # of grapes
1.68a + 2.48(a - 2) = 13.76
1.68a + 2.48a - 4.96 = 13.76
4.16a = 18.72
a = 4.5; Apples
(a - 2) = 2.5; Grapes

If there are 22 successes in a sample with a size of 40, what is the sample
proportion?
A. 0.55
B. 0.65
C. 0.44
D. 0.22
Answer:
A
Step-by-step explanation:
22 successes out of a group of 40 means 22/40 were good. Now, simplify 22/40. Both can be divided by 2.
22/2 = 11
40/2 = 20
Now you have 11/20. Put this in decimal form and you have 0.55
Option A answer is 0.55
What is the proportion of a sample?The proportion of a sample is the ratio of the number of successes or defeats to the total size of the sample, it is used for understanding which trend is more followed and also has many uses in the real world.
The solution to the given problemThe size of the sample is 40.
There are 22 successes in the sample.
To find the proportion of success we have to find the ratio of 22 and 40 which is 11:20, and in numerical terms 0.55
Hence option A is correct, the proportion is 0.55

Answer:
Meg makes more money per hour.
Step-by-step explanation:
Given that,
Meg worked for 4 hours and earned $31 . Gabby worked for 5 hours and earned $37.50.
We need to find who makes more money per hour.
For Meg,
Money per hour = [tex]\dfrac{31}{4}=\$7.75[/tex]
Fr Gabby,
Money per hour = [tex]\dfrac{37.50}{5}=\$7.5[/tex]

5x + 4y = -7
-5x - 2y = 1
Answer:
y=-3
x=1
(1,-3)
Step-by-step explanation:
5x+4y=-7
-5x-2y=1
Cancel +5x - 5
2y=-6
y=-3
5x-12=-7 or -5x+6=1
5x=5 -5x=-5
x=1 x=1
Answer:
y = -3, x = 1
or
(1, -3)
Step-by-step explanation:
5x + 4y = -7
-5x - 2y = 1
add the two equations together
0x + 2y = -6
2y = -6
2y/2 = -6/2
y = -6/2
y = -3
now substitute y = -3 into either of the equations
5x + 4y = -7
5x + 4(-3) = -7
5x - 12 = -7
5x = -7 + 12
5x = 5
x = 1

One father is 70 inches tall and the residual for his son’s height is 2.5. What is the son’s actual height?
71.7 inches
74.2 inches
76.7 inches
82.3 inches
Answer: C
Step-by-step explanation:
Since the heights of the men are assumed to be normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = heights of the men.
µ = mean height
σ = standard deviation
From the information given,
µ = 70.7 inches
σ = 2.1 inches
The probability that they have a mean height greater than 71.7 inches is expressed as
P(x > 71.7) = 1 - P(x ≤ 71.7)
For x = 71.7
Since n = 36, then
z = (71.7 - 70.7)/2.1/√36 = 2.86
Looking at the normal distribution table, the probability corresponding to the z score is 0.998
P(x > 71.7) = 1 - 0.998 = 0.002
