A random sample of 184 students at South High School were surveyed on whether they would prefer going to a movie or a concert. T

he results are shown in the relative frequency table. A 4-column table with 4 rows. The first column has no label with entries 10th, 11th, 12th, total. The second column is labeled movie with entries 0.18, 0.16, 0.24, 0.58. The third column is labeled concert with entries 0.15, 0.18, 0.09, 0.42. The fourth column is labeled total with entries 0.33, 0.34, 0.33, 1.00. Which statements are correct? Check all that apply. The marginal relative frequency for 10th graders is 0.18. 42% of the students prefer a concert over a movie. A greater ratio of 11th graders prefer a concert to a movie. More 12th graders were surveyed than any other grade level. The difference in the percent of students who prefer a movie over a concert is16%.

Answer:

B. 42% of the students prefer a concert over a movie

C. A greater ratio of 11th graders prefer a concert to a movie

E. The difference in the percent of students who prefer a movie over a concert is 16%

Step-by-step explanation:

No. movie concert total

10th - 0.18 - 0.15 - 0.33

11th - 0.16 - 0.18 - 0.34

12th - 0.24 - 0.09 - 0.33

Total - 0.58 - 0.42 - 1.00

0.42 is 42%

(0.58 -0.42) × 100 = 16%

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

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

A diver dives from the board at a local swimming pool. Her height, y, in metres, above the water in terms of her horizontal dist
Aneli [31]

Answer:

4 meters

Step-by-step explanation:

Given a quadratic equation in which the coefficient of x^2 is negative, the parabola opens up and has a maximum point. This maximum point occurs at the line of symmetry.

Since the divers height, y is modeled by the equation

y= -x^2 + 2x + 3

Step 1: Determine the equation of symmetry

In the equation above, a=-1, b=2, c=3

Equation of symmetry, x=-\dfrac{b}{2a}

x=-\dfrac{2}{2*-1}\\x=1

Step 2: Find the value of y at the point of symmetry

That is, we substitute x obtained above into the y and solve.

y(1)= -1^2 + 2(1) + 3=-1+2+3=4m

The maximum height of the diver is therefore 4 meters.
