In a class of students, the following data table summarizes how many students play
an instrument or a sport. What is the probability that a student chosen randomly
from the class plays a sport or an instrument?
Answer:
19/28
Step-by-step explanation:
People who count: 4 + 2 + 13 = 19
Total amount of pplz: 19 + 9 = 28
Answer:
15/28
Step-by-step explanation:
The total amount of students in the class is 28. This will be useful for later.
From this table, we can see that 2 people play sports alone and 13 play an instrument alone. Since it says the number of students that play a sport or an instrument, this means that the top left box is not counted. This leaves you with an answer of 15/28.
The radius of a sphere is increasing at a rate of 5 mm/s. How fast is the volume increasing (in mm3/s) when the diameter is 60 mm
Answer:
The volume of the sphere is increasing at a rate of 56,549 cubic millimeters per second.
Step-by-step explanation:
Volume of a sphere:
The volume of a sphere is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
In which r is the radius.
Solving this question:
The first step do solve this question is derivating V implictly in function of t. So
[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]
The radius of a sphere is increasing at a rate of 5 mm/s.
This means that [tex]\frac{dr}{dt} = 5[/tex]
Diameter is 60 mm
This means that [tex]r = \frac{60}{2} = 30[/tex]
How fast is the volume increasing (in mm3/s) when the diameter is 60 mm?
This is [tex]\frac{dV}{dt}[/tex]. So
[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]
[tex]\frac{dV}{dt} = 4\pi*30^2*5 = 900*20\pi = 56549[/tex]
The volume of the sphere is increasing at a rate of 56,549 cubic millimeters per second.

The figure shown is created by joining three rectangles. Enter the area of the figure, in square centimeters. Round to the nearest hundredth.
Answer:
46.75
Step-by-step explanation:
first, separate the floor into 3 different rectangles to calculate the area and then add them together.
area of rec=L*B
rec 1: 5.5*4=22
rec 2: (6.5-3)*(8.5-3-4)=5.25
rec 3:3*6.5=19.5
Then:
22+5.25+19.5=46.75

The missing value in the equation is 2.When we substitute 2 for the missing number, the LHS value equals the RHS value.So, response 2 is the right one.
What is the equation?A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.
Given equation;
y=5(?)^x
The given data from the table;
X 0 1 2 3 4 5 6
Y 5 10 20 40 80 160 320
If we put the value 2 on the missing place it will satisfy the relation;
y=5(?)ˣ
5=5(2)⁰
5=2×1
5=5
10=5(2)¹
10=5×2
10=10
20=5(2)²
20=5×4
20=20
The value of LHS is equal to the RHS when we put 2 on the place of missing value.
Hence 2 is the correct answer.

Solve 2Q + 5s=r for s and show ALL your steps.
Answer:
2q-r= 5s
divide both sides by 5
2q-r/s =5s/5
therefore S= 2q-r/s
Answer:

Subtract 2Q from both sides
2Q + 5s − 2Q = r − 2Q

5s = r − 2Q
Divide both sides by 5

2. Two puppies together weigh 22 kilograms 300 grams. If one
puppy weighs 9 kilograms 500 grams, how heavy is the other
puppy?
Tip: 1 kg = 1000 g
answer asap
Answer:
B = 12800 grams or 12kg 800 grams.
Step-by-step explanation:
Let the two puppies be A and B respectively.
Translating the word problem into an algebraic expression, we have;
A + B = 22kg 300g
A = 9kg 500g
Conversion;
1 Kilograms = 1000 grams.
9kg 500g = 9*1000 + 500 = 9500 grams
22kg 300g = 22*1000 + 300 = 22300 g
Substituting into the above formula, we have;
9500 + B = 22300
B = 22300 - 9500
B = 12800 grams or 12kg 800 grams

Answer:
20 cubic meters
Step-by-step explanation:
Volume of a rectangular prism = length * width * height
Dividing the figure into 2 rectangular prisms
Volume of First rectangular prisms = 4m * 2m * 1m
Volume of First rectangular prism = 8m^3
Volume of second rectangular prism = 4m * 3m * 1m
Volume of second rectangular prism = 12m^3
Taking the sum
Volume of the figure = 8m^3 + 12m^3
Volume of the figure = 20 cubic meters

Ms. Mason is picking a movie theater to take her family to when they come to visit.
Cinemark is offering a package of 8 tickets for $82.00
Alamo Drafthouse is selling 5 tickets for $47.50
Which movie theater is the better deal? How do you know?
Answer:
Alamo Drafthouse
Step-by-step explanation:
Divide 82 by 8 to get the cost per ticket of Cinemark.
82 / 8 = 10.25
Divide 47.5 by 5 to get the cost per ticket of Alamo Drafthouse.
47.5 / 5 = 9.5
Alamo Drafthouse has the better deal.

The given equation is :
6x+2y=14
We need to write it in the function form.
Taking 2 common from both sides,
2(3x+y)=2(7)
So,
(3x+y)=7
Subtract 3x from both sides,
y+3x-3x=7-3x
y = 7-3x
So, the correct option is (c).
2. f(x) = 3x-4
We need to find f(2). Put x = 2 in the above function.
f(2) = 3(2)-4
= 6-4
= 2
The correct option is (D).

Step-by-step explanation:
A basketball player has a 0.654 probability of making a free throw. If the player shoots 13 free throws, what is the probability that she makes less than 6 of them?
Insert the correct symbol to represent this probability.
Provide your answer below:
P(X
5)
Using the binomial distribution, it is found that there is a 0.0432 = 4.32% probability that she makes less than 6 of them.
-----------------------
For each throw, there are only two possible outcomes. Either she makes it, or she misses it. The probability of making a throw is independent of any other throw, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
x is the number of successes. n is the number of trials.p is the probability of a success on a single trial.The probability of making less than 6 is:
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{13,0}.(0.654)^{0}.(0.346)^{13} \approx 0[/tex]
[tex]P(X = 1) = C_{13,1}.(0.654)^{1}.(0.346)^{12} \approx 0[/tex]
[tex]P(X = 2) = C_{13,2}.(0.654)^{2}.(0.346)^{11} = 0.0003[/tex]
[tex]P(X = 3) = C_{13,3}.(0.654)^{3}.(0.346)^{10} = 0.0020[/tex]
[tex]P(X = 4) = C_{13,4}.(0.654)^{4}.(0.346)^{9} = 0.0093[/tex]
[tex]P(X = 5) = C_{13,5}.(0.654)^{5}.(0.346)^{8} = 0.0316[/tex]
Then
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0 + 0 + 0.0003 + 0.0020 + 0.0093 + 0.0316 = 0.0432[/tex]
0.0432 = 4.32% probability that she makes less than 6 of them.
