Answer:
option A is the correct option
Answer:
42% of the students prefer a concert over a movie.
A greater ratio of 11th graders prefer a concert to a movie.
The difference in the percent of students who prefer a movie over a concert is16%.
Step-by-step explanation:
10th 11th 12th total
movie .18 .16 .24 .58
concert .15 .18 .09 .42
total .33 .34 .33 1
The marginal relative frequency for 10th graders is 0.18. This is an incomplete statement
The marginal frequency is a number not a percent
42% of the students prefer a concert over a movie. 42% preferred a convert to the 58% who preferred a movie. True
A greater ratio of 11th graders prefer a concert to a movie. 18/100 concert to 16/100 for the movie for 11th graders
18:16 This is true
More 12th graders were surveyed than any other grade level.
There were more 11th graders surveyed (34%) to (33%) for 12 graders False
The difference in the percent of students who prefer a movie over a concert is16%. True
-5/6 <-2/3 would be your answer
hope this helps
If y = x^2 + 2x and y = 3x + 20
<span>Then </span>
<span>x^2 + 2x = 3x + 20 </span>
<span>x^2 - x - 20 = 0 </span>
<span>(x - 5)(x + 4) = 0 </span>
<span>x = 5, - 4 </span>
<span>For x = 5, y = 3(5) + 20 = 35 </span>
<span>For x = - 4, y = 3(-4) + 20 = 8 </span>
<span>(5, 35), (-4, 8)</span>
Given :
Runs scored by home team is (x + 7).
Runs scored by visiting team is (3x - 7).
To Find :
An expression to find how many more runs the home team scored than the visiting team. Then evaluate the expression if the value of x is 6.
Solution :
Let, number of more runs the home team scored than the visiting team is R.
R = (x + 7) - (3x - 7)
R = 14 - 2x
Now, putting value of x = 6 in above equation, we get :
R = 14 - 2( 6 )
R = 2
Hence, this is the required solution.
