Step-by-step explanation:
I took the test
Probability of the intersection of being a junior and participating in marching band = 0.16
What do we mean by Probability?The probability of an event taking place is the numeric value determining how likely that particular event is to take place.
It is determined by the formula,
Probability( Event ) = Number of favorable outcomes for that event/Total number of outcomes.
The summation of all probabilities for a given event is 1.
What do we mean by the intersection of Probabilities?The intersection of Probabilities is just the product of the two probabilities.
How do we solve the given question?In the question, we are said that students have equal probabilities of being freshmen, sophomores, juniors, or seniors.
∴ Probability(A student is a junior) = 1/4 = 0.25, as we have 4 cases all equally probable.
Now, we are said that a student is 64% likely to join the marching band.
∴ Probability( A student joins marching band) = 64% = 64/100 = 0.64.
We are asked to find the probability of the intersection that a student is a junior and participates in the marching band.
Probability( A student is a junior and joins marching band) = Probability( A student joins marching band)* Probability( A student is a junior)
∴ Probability( A student is a junior and joins marching band) = 0.64*0.25 = 0.16
∴ Probability of the intersection of being a junior and participating in marching band = 0.16

ASAP "PLEASE HELP"Farah rolled a number cube 84 times. The outcome of "2" occurred 12 times. What is the experimental probability of rolling 2. Write your answer as fraction in simplest form. Please I only have 1 hour left
Answer: [tex]\dfrac{1}{7}[/tex]
Step-by-step explanation:
Given
A cube is rolled 84 times
2 occurred 12 times
Experimental probability is determined by the use of data obtained in the experiment.
Therefore, the experimental probability of obtaining 2 on 84 rolls of the die is
[tex]\Rightarrow P=\dfrac{12}{84}\\\\\Rightarrow P=\dfrac{1}{7}[/tex]

Liz walks 1/2 mile in 20 minutes on Monday and 3 3/4 in 150 minutes on Sunday is this proportional or non -proportional
Answer:
proportional
Step-by-step explanation:
so if 1/2 is 20, 1/4 is 10, and 1 whole mile is 40.
40 + 40 + 40 + 10 + 10 + 10 = 150
because we used the reasoning from the first part and it turned out correct, it is proportional
How do you find the radius of a Tetrahedron?
My own question no answer choices.
No bit links plz. 15 points and plz describe well.
Answer:
The center of the tetrahedron divides each of the four heights (or medians) in the ratio 1:3 (in an equilateral triangle the corresponding ratio is 1:2). The smaller part is also the radius of the inscribed sphere. Therefore the radius of this sphere is one quarter of the height or 9 in your case.

Samantha saves at least 10% of the money she earns each month. She earns $120 each month for a year. Which inequality describes the total amount Samantha saves?
Step-by-step explanation:
10 % each month is $12.00 12 months in a year 12 x 12.00 = $144.00
The inequality to describe the total amount Samantha saves is s > 15.
The correct option is (A).
What is Inequality?Inequalities are mathematical formulas in which neither side is equal. We compare two values in inequality.
As per the given data:
We are given that Samantha saves at least 10% of her monthly salary.
Samantha is earning $150 each month for a year.
To find the amount Samantha at least saves in a month:
= 10% of her monthly salary
= 10% × 150
= 10/100 × 150
= 15 dollars
As she is saving, at least 15 dollars, then the inequality to describe her savings is as follows:
savings > 15
The inequality to describe the total amount Samantha saves is s > 15.
Hence, The inequality to describe the total amount Samantha saves is
s > 15.

At a football game, a vender sold a combined total of 208 sodas and hot dogs. The number of hot dogs sold was 44 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold.
Answer:
the number of sodas sold and the number of hot dogs sold is 126 and 82 respectively
Step-by-step explanation:
Given that
The total of sodas and hot dogs sold is 208 sodas
And, the number of hot dogs was 44 less than the number of sodas sold
We need to find out the number of sodas sold and the number of hot dogs sold
Let us assume the number of sodas sold be x
So, the number of hot dogs be x - 44
Now as per the given question
x + x - 44 = 208
2x = 208 + 44
2x = 252
x = 126
So, the number of hot dogs is
= 126 - 44
= 82
hence, the number of sodas sold and the number of hot dogs sold is 126 and 82 respectively

How to solve this. I am very confused.
To solve, we will need to plug in -5 for x in both instances.
|-5 + 2| / -5 + 2
|-3| / -3
Now, these absolute value bars may be a bit puzzling. What we have to do is take the absolute value of the number inside of the brackets. Meaning, that if the number is negative, we make it positive, and if the number is positive, then it stays positive.
3 / -3
-1
Hope this helps!! :)
Answer:
-1
Step-by-step explanation:
Plug in the value for x (-5) into the equation: [tex]\frac{|(-5)+2|}{(-5)+2}[/tex]
Simplify:[tex]\frac{|-3|}{-3}[/tex]
Take absaloute value to simplify further:
(All absaloute value means (which is what these bars represent: | |) is how far away a number is from zero, so the number will always be its positive counterpart if it is not already positive):
[tex]\frac{3}{-3}[/tex]
Now simplify (divide 3 by -3) to get your answer:
-1
