In a math class with 26 students, a test was given the same day that an assignment
was due. There were 17 students who passed the test and 18 students who completed
the assignment. There were 15 students who passed the test and also completed the
assignment. What is the probability that a student who failed the test completed the
homework?
Answer:
The propability would be 4/26 students who failed the test but completed the
homework
Step-by-step explanation:
The Probability that a student who failed the test completed the homework is [tex]\frac{3}{26}[/tex]
What is Probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur,
Given,
Total number of students = 26 students
Number of students who completed the assignment = 18 students
Number of students who pass the test and also completed the assignment = 15 students
Number of students who completed the assignment and fail the test = 18 -15 = 3 students
Then,
Probability = Number of favorable outcome / Total number of outcome
Probability that a student who failed the test completed the homework = [tex]\frac{3}{26}[/tex]
Hence, The Probability that a student who failed the test completed the homework is [tex]\frac{3}{26}[/tex]

1) (2 points) Imagine a 21-gonal prism. How many total faces does this prism have? Provide a clear
and detailed justification for your answer, using appropriate vocabulary, that does not rely on a
formula.
Answer: There are 23 faces total.
Explanation:
This is because there are 21 lateral faces, each of which are a rectangle. Then there are the 2 base faces which are each 21-gons. A 21-gon is a 21 sided polygon. So we have 21+2 = 23 faces total.

which scatterplot represents the data given in the table which shows the number of apples in bags and the weights of the bags?
Answer:C
Step-by-step explanation: Because I took the pre test!
The scatterplot that represents the data given in the table is Scatterplot C.
Option C is the correct answer.
What is a scatterplot?A scatterplot is a type of graphical display that is used to represent the relationship between two continuous variables.
In a scatterplot, each point represents the values of the two variables, with one variable being plotted along the x-axis and the other variable being plotted along the y-axis.
The position of each point on the graph represents the values of both variables for that particular observation.
We have,
From the table,
We see that,
Number of apples = 4 has weight 2lb and 3lb.
Number of apples = 5 has weight 2lb and 3lb.
Number of apples = 6 has weight 3lb and 5lb.
Number of apples = 7 has weight 4lb and 6lb.
Number of apples = 8 has weight 5lb and 7lb.
Now,
We see that in the scatter plot of option C, the table is represented.
Thus,
The scatterplot that represents the data given in the table is Scatterplot B.

Answer:
the answer is 59 (I got it on khan academy)
Step-by-step explanation:
59 degrees is the measures of the minor arc YZ if diameter of a circle is XZ
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given that diameter of a circle is XZ
We have to find the measure of arc YZ.
11w+5w+4=180
Add the like terms
16w+4=180
Subtract 4 from both sides
16w=176
Divide both sides by 16
w=176/16
w=11
Now plug in w value of yz
yz=5w+4
=5(11)+4
=55+4
=59 degrees
Hence, 59 degrees is the measures of the minor arc YZ.

The number of students enrolled at a college is 16,000 and grows 6% each year.
After 22 years, how many students will be enrolled?
Answer:
a) The initial amount a is —> 16,000
b) The percent rate of change is 6%, so the growth factor b is 1+ —> 0.06 = 1.06
c) To find the number of students enrolled after one year, you calculate 16,000 —> • 1.06
d) answer is y= 16,000 • 1.06*x
e) answer is 57,657
Step-by-step explanation:
After 22 years, there are 57,600 students will be enrolled.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The number of students enrolled at a college is 16,000 and grows 6% each year.
We know that;
A = P (1 + r)ⁿ
Here, P = 16,000
r = 6%
n = 22 years
Hence, After 22 years, number of students will be enrolled is,
A = 16,000 (1 + 0.06)²²
A = 16,000 (1.06)²²
A = 16,000 x 3.60
A = 57,600
Thus, After 22 years, there are 57,600 students will be enrolled.

hi im 7th grade and i feel like people think i smell when i do everything to not smell. i wake up take a shower with soap aplly deoderant and brush teeth. any tips
Answer:
Step-by-step explanation:
This might be a hygiene problem. What causes the unpleasant smell is the bacteria that build up on your sweaty skin and react with sweat and oils to grow and multiply when sweat reacts with bacteria on the skin. These bacteria break down proteins and fatty acids, causing body odor in the process. If deodorant isn’t good enough , I recommend perfume, the perfume smell lasts longer than deodorant I would think. But shower everyday, full clean down, but if ur hygiene is ok, I recommend going to the doctor for a checkup. Hopefully your problem will be resolved. Also use lotion.

Answer:
y(5 + 8)
Step-by-step explanation:
I think what this problem wants us to do is take y out of this expression. 5y divided by y is 5 and 8y divided by y is 8, so we would get that this expression is y(5 + 8).
If you wanted to simplify, you would get y(13), which is 13y.
