Answer:
The expected number of students to prefer summer=245
Step-by-step explanation:
Step 1
Determine the number of students that prefer summer as their favorite season, and the sample size
number that prefer summer=7
sample size=10
Step 2
Determine the probability of a student picking summer as their favorite season as shown;
Probability=number that prefer summer/sample size
Probability=7/10=0.7
Step 3
Determine the total number of students out of the total population that can be expected to prefer summer as follows;
Expected number of students=probability×total number of students
where;
probability=0.7
total number of students=350
replacing;
Expected number of students=(0.7×350)=245
The expected number of students to prefer summer=245
The total of Leiff’s online purchases will be $119.32.Option d is correct.
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
If the video game's original price is $128 and the discount is 15%, then Leiff paid (100-15) = 85% of the original price for the item.
Consequently, the video game's price is as follows:
(0.85 x 128) = $108.80.
Leif must contribute an additional 5.3% of the new price, so
(100 + 5.3) = 105.3% of the new price
= (1.053 x 108.8) = $114.57
Including the video game's shipping cost,
114.57 + 4.75 = $119.32
Thus, the total price is $119.32

Answer:
D. 860 square inches
Answer:
D: 860 square inches
Step 1.
Remember:
w = 8
x = 5
y = 20
z = 11.3
Let's start with the bottom rectangular prism. The front and back of it is x * x
(5 * 5), so the from and back is 25 + 25 = 50.
The three long sides are x * y (5*20), so the three long rectangles are 100 * 3 = 300. The bottom shape is 350 in total.
Step 2.
The top two rectangles are w * y, (8 * 20) so the two top rectangles are 160 * 2 = 320.
The triangles are w * w / 2 (8 * 8/2) (64 / 2) (32), so the two triangles are 64.
We subtract x from z to get 6.3.
Then, we multiply 6.3 by 20. We get 126. Finally, we add all the values together to get our final answer.
350 + 384+126 = 860
Our answer is D: 860.
A. 8x = 16
B. 4x = 16
C. 5x = 16
D. 5y = 16
By substituting y = 2x into the second equation and combining like terms, we get the equation 8x = 16.
This question is from the field of Algebra. You are asked to substitute the first equation into the second equation, then simplify by combining like terms. Substituting y = 2x from the first equation into the second equation 2x + 3y = 16, we replace y with 2x, thus transforming the second equation into 2x + 3(2x) = 16. Distributing the 3 to the 2x within the parentheses gives us 2x + 6x = 16. By combining the like terms on the left side, we get 8x = 16 which is option A.
