There are 215 total students in the band.
There are 27 seniors in the band.
The probability is found by dividing the number of seniors in the band by the TOTAL number of students in the band.
P(S|B) = 27/215 = 0.1255813953
You have to round off the answer too the nearest tenth.
P(S|B) = 0.13

For Volume: 54ft^3
For Surface Area: D. 90ft^2
Step-by-step explanation:
Volume formula of rectangular prism: V = L * W * H
By replacing the variables with the given numbers we get the following:
V = 3ft * 3 ft * 6 ft
By multiplying, we get 54ft^3.
Surface Area formula of rectangular prism: SA = 2 (L*W + L*H + W*H)
By replacing the variables with the given numbers we get the following:
SA = 2 (3*3 + 3*6 + 3*6)
By multiplying, we get:
SA = 2 (9 + 18 + 18)
We add the numbers inside the parenthesis, then we multiply by two to get the following:
SA = 90 ft^2

Five friends agree to save money for a graduation road trip. They decide that
each of them will put $0.25 in the fund on the first day of May, $0.50 on the
second day, $0.75 on the third day, and so on. At the end of May, there will be
$_ in their fund. (Hint: There are 31 days in May.)
Answer:
$620
Step-by-step explanation:
First you have to figure out the amount one of them would add which is $124. You would do this by adding .25+.50+.75+1 ect. Then once you know how much one of them would add you do 124(5) and get $620.

1) Andy drove 840 miles in 12 hours. How far could he drive in 3 hours?
Unit rate (speed) _____
Distance _____
2) Pira drives 825 miles to California. The trip takes 17 hours. He uses 38 gallon of gas on the trip, which costs him $125.
Find his speed
Find his gas mileage
Find the unit price he paid for gas.
Answer:
Step-by-step explanation:
Mr. Anderson drove 168 miles in 3 1/2 hours: d1 = 168 mi
t1 = 3 1/2 hr
t1 = 3.5 hr
v1 = the first rate
v1 = d1/t1
v1 = 168/3.5
v1 = 48 mph
He then drove 2 1/4 hours at a rate of 5 miles an hour faster than the first rate:
t2 = 2 1/4 hr
t2 = 2.25 hr
v2 = v1 + 5
v2 = 48 + 5
v2 = 53 mph
d2 = the distance
d2 = v2*t2
d2 = 53*2.25
d2 = 119.25 mi
during the total time 3 1/2 + 2 1/4 = 5 3/4 hr Mr. Anderson drove:
d1 + d2 = 168 + 119.25 = 287.25 mi.

Answer:
x = 58°
Step-by-step explanation:
First, we need to find the green angle on the bottom left of the triangle.
We know that straight lines are supplementary, or equal 180 degrees, so we can say that 114° + a (a variable representing the measure of the angle) = 180°.
Equation:
114 + a = 180
Solve:
114 + a = 180
-114 -114
a = 66
Therefore, the value of the green angle is 66 degrees.
Now, we need to find the value of angle x.
We know that the sum of the angles in a triangle is 180 degrees.
So, 56° + 66° + x = 180°
Equation:
56 + 66 + x = 180
Add:
56 + 66 + x = 180
122 + x = 180
Subtract:
122 + x = 180
-122 -122
x = 58
Therefore, x is 58 degrees.
Answer:
58
Step-by-step explanation:
An exterior angle is equal to the two remote interior angles. It would be easier to understand that just by adding the numbers in an equation.
Exterior angle = 114
Remote interior angles = x and 56
exterior angle = sum of x and 56 which are the two remote interior angles.
x + 56 = 114 Subtract 56 from both sides.
x+56-56=114-56
x = 58

a sector with a radius of 15 cm has a central angle measure of 8π/5 what is the area of the sector
Answer:
area of the sector = 360π cm²
Step-by-step explanation:
To calculate the area of the sector, we will follow the steps below;
First write down the formula for calculating the area of a sector.
If angle Ф is measured in degree, then
area of sector = Ф/360 × πr²
but if angle Ф is measured in radians, then
area of sector = 1/2 × r² × Ф
In this case the angle is measured in radiance, hence we will use the second formula
From the question given, radius = 15 cm and angle Ф = 8π/5
area of sector = 1/2 × r² × Ф
=1/2 × 15² × 8π/5
=1/2 ×225 × 8π/5
=360π cm²
area of the sector = 360π cm²

The perimeter of a rectangular photograph is 28 inches. If the width of the photo is 5 inches, how tall is the photo?
Answer:
it is 9 inches tall
Step-by-step explanation:
p=2L + 2W
28=2L + 2 x 5
28=2L +10
28-10=2L
18=2L
L=9
Answer:
9 inches.
Step-by-step explanation:
Since the width of the rectangle is 5 inches, We have to times it by 2 which is 10.
Then deduct it from the perimeter of 28, which equals to 18. We have to divide it by 2 so we can find out how tall each side is. 18 divided by 2=9.
Hope that helps.

Which of the following side lengths can form a triangle?
23, 28, and 55
24, 24, and 47
15, 30, and 45
8, 17, and 25
Answer: 24, 24, 47
Step-by-step explanation:
In order to form a triangle, the sum of two sides must be GREATER than the third side for all combinations.
a + b > c & a + c > b & b + c > a
23 + 28 = 51 which is NOT greater than 55
15 + 30 = 45 which is NOT greater than 45
8 + 17 = 25 which is NOT greater than 25
24 + 24 > 47 & 24 + 47 > 24 & 24 + 24 > 27
all combinations are true so these side lengths can form a triangle
factory makes car batteries. The probability that a battery is defective is 1/14. If 400 batteries are tested, about how many are expected to be defective?
A) 14
B) 371
C) 29
D)35
The required number of defective batteries is 29 out of 400 batteries tested. Option C. is correct.
The probability that a battery is defective is 1/14. The probability that a battery is defective is 1/14. If 400 batteries are tested, how many are expected to be defective s to be determined?
Probability can be defined as the ratio of favorable outcomes to the total number of events. it can be denoted as,
Probability = number of favorable outcomes / total sample space
The probability that a battery is defective given by,
P(D) = 1/14 = 0.072 or 7.2%
400 batteries are tested while multiplying the defective percentage to the number of batteries it gives the defective number of batteries
Number of defective batteries,
= 400 * 7.2%
= 400 * 7.2/100
=≈ 29
Thus, the required number of defective batteries is 29 out of 400 batteries tested. Option C. is correct.
