Answer:
42.5%
Step-by-step explanation:
First we have to complete the table. We know that there are forty part time students so sum(f)=n=40. So, for two courses frequency is 40-11-12=17.
The relative frequency is the proportion of respective frequency and the sum of frequency. So, the missing relative frequency for 1st course is 11/40=0.275.
The missing relative frequency can also be computed as by subtracting given relative frequencies from 1 as sum of relative frequencies is 1. So, 1-0.425-0.3=0.275.
The cumulative frequency of respective class is the sum of frequency of previous classes and frequency of respective class. The missing cumulative frequency is 11+17+12 or 28+12= 40.
So, the complete table is
# of Courses Frequency Relative Frequency Cumulative Frequency
1 11 0.275 11
2 17 0.425 28
3 12 0.3 40
The percent of students takes exactly two courses=0.425*100=42.5%

1. In winter with heavy snow,
the animals in Yellowstone cannot freely roam to find food,
so hay is dropped for them from helicopters. A helicopter is 180 feet above the ground
drops a bale of hay while the helicopter itself is rising at 32 feet per second. The height (S)
in feet of the bale as a function of time is given by:s(t) = -16t2 + vit + Si
where t is the time since the bale was dropped off the helicopters (in seconds), V is the
initial velocity, and Si is the initial height.

Write the equation in slope-intercept form: 6x + 2y = 10.
Answer: y=-3x+5
Step-by-step explanation:
6x+2y=10
Solve for y
2y=-6x+10
y=-3x+5
Answer: y = -3x + 5
Step-by-step explanation:
Slope intercept form is y = mx + b so all you need to do is put the equation into that format.
6x + 2y = 10
2y = 10 - 6x
y = -3x + 5
Find the slope of the line that is perpendicular to y= -1/2x+11
Answer:
The slope is 2
Step-by-step explanation:
The sign changes and the slope will be be the reciprocal (flipped)
Answer:
2
Step-by-step explanation:
hi! to find the perpendicular slope, you have to flip the fraction to its reciprocal and use the opposite sign (- or +).
-1/2's reciprocal is -2, and its opposite sign is +, so the slope of the line that is perpendicular to this line is 2.

Do you have a specific sample question?
Given f(x) = -3x + 4, solve for x when f(x) = 1
(Will mark brainliest)
Answer:
x=1
Step-by-step explanation:
f(x) is a fancy way of saying Y. So whenever you see that, you can just say its y= something.
y=-3x+4
1=-3x+4
Move the -3x to the other side where the one is. By doing this, the 3x will become positive.
3x+1=4
Now just subract one from 4
3x=3
And divide 3 from both sides.
x=1

Kal is decorating the outside edge of a square
bulletin board. He needs to know the side length
of the bulletin board. The area of the bulletin
board is n square feet.
Which expression shows the side length, in feet,
of the bulletin board?
The expression shows the side length, in feet, of the bulletin board is √n feet option (A) is correct.
What is a square?It is defined as a two-dimensional geometry that has four sides and four vertices. The sides of the square are equal in length. It is a regular quadrilateral.
It is given that:
Kal is decorating the outside edge of a square bulletin board.
The figure is a square and the area of the square is n square feet where n is any real number.
As we know,
The area of the square = side²
The area of the square = n square feet
n = side²
Square root on both sides:
side = √n feet
Thus, the expression shows the side length, in feet, of the bulletin board is √n feet option (A) is correct.
