60% of students in a class use TikTok. 20% of those students post their own videos. If 3 students post videos to TikTok, how many students are in the class?
Answer:
25 students
Step-by-step explanation:
Let x = no. of students in the class
.6x = no. of students that use TT
.2(.6x) = no. of students that post videos
.2(.6)x = 3
.12x = 3
x = 25 students
Find an ordered pair (x, y) that is a solution to the equation.
2x-y=9
VERY EASY, WILL GIVE 50 POINTS FOR CORRECT ANSWER ASAP AND WILL GIVE BRAINLIEST.
Answer:
(80, 120)
Step-by-step explanation:
y - 40 + y = 200
2y = 240
y = 120
x = 120 - 40
x = 80

Two college instructors are interested in whether or not there is any variation in the way they grade math exams. They each grade the same set of 10 exams. The first instructor's grades have a variance of 58.9. The second instructor's grades have a variance of 84.8. Test the claim that the first instructor's variance is smaller. (In most colleges, it is desirable for the variances of exam grades to be nearly the same among instructors.) The level of significance is 10%. (Recall: that the larger of the 2 variances needs to be in the numerator as the test is 1-tailed to the right)
Answer:
Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
Step-by-step explanation:
1)Formulate the hypothesis that first variance is equal or greater than the second variance
H0: σ₁²≥σ₂² against the claim that the first instructor's variance is smaller
Ha: σ₁²< σ₂²
2) Test Statistic F= s₂²/s₁²
F= 84.8/ 58.9= 1.4397
3)Degrees of Freedom = n1-1= 10-1= 9 and n2 = 10-1= 9
4)Critical value at 10 % significance level= F(9,9)= 2.4403
5)Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
Giving out the 15 points help please number 2.

Suppose that you are attempting to buy a house, and you are bargaining with the current owner over the sale price. The house is of value $200,000 to you and $100,000 to the current owner; so, if the price is between $100,000 and $200,000, then you would both be better off with the sale. Assume that bargaining takes place with alternating offers and that each stage of bargaining (an offer and a response) takes a full day to complete. If agreement is not reached after seven days of bargaining, then the opportunity for the sale disappears (you will have no house and the current owner has to keep the house forever). Suppose that you discount the future according to the discount factor 0.3 per day and the current owner discount the future at discount factor of 0.6 per day. The real estate agent has allowed you to decide whether you will make the first offer. Should you make the first offer or let the current owner make the first offer? Why? Suppose that you have to make the first offer, what will be your offer that is going to be acceptable to the current owner?
Answer:
the answer is to make the first offer!
Step-by-step explanation:
Since the surplus ($100000) is rapidly depleting, and though the second individual collects the whole surplus, it is already less than half of the surplus from the previous day. So, once you make the first bid, any offer above 100,000 would be fair to the second person and if he rejects the offer, he will only be able to get 100,000 the next day. You will raise the payout by 100000(1 ) this way.
A rectangle has an area of 63 square inches. The width of the rectangle is 6 inches. What is the rectangle’s length, in inches?
When you know the area and one side of a rectangle, divide the area by the known side to find the length of the other side.
Length = 63/6
Length = 10.5 inches

Answer:
B
Step-by-step explanation:
There is a 1/4 probability of getting an A out of a bag with letter MATH
For B) There are two A's our of 8 letters is ADMIRALS.
2/8 is the same as 1/4
The answer is B
A) is wrong because that 1/6
C) is wrong because that's 1/8
D) is wrong because that's 2/9
Answer:
B
Step-by-step explanation:
Probability of finding A in a word = number of A / number of letters in that word
Probability of finding A in MATH = 1/4
A. Probability of finding A in BECAME = 1/6
B. Probability of finding A in ADMIRALS = 2/8 = 1/4
C. Probability of finding A in USERNAME = 1/8
D. Probability of finding A in AFTERMATH = 2/9
So we have a match with option B

Solve for y: 3d = 7y + 5
Answer:
d = [tex]\frac{7y+5}{3}[/tex]
Step by step explanation:
3d = 7y+5
Divide both sides by 3
[tex]\frac{3d}{3}[/tex]= [tex]\frac{7y}{3}[/tex]+ [tex]\frac{5}{3}[/tex]
Simplify
[tex]\frac{7y+5}{3}[/tex]

Help plz, these questions are very confusing :/
Answer:
1.
cos ∅=b/h=24/25
:.b=24
h=25
by using Pythagoras law
h²=p²+b²
25²=p²+24²
p²=25²-24²
p=√7²=7
now
sin ∅=P/h=7/25
tan∅=p/b=7/24
2.cos ∅ is your answer
sec∅-sin∅tan∅
1/cos∅-sin²/cos∅
(1-sin²∅)/cos∅
cos²∅/cos∅
cos∅
3.
tan²∅-sec²x
sin²∅/cos²∅-¹/cos²∅
