Answer:
The total cost could be $36
Step-by-step explanation:
36/6 = 6
6 is less than 8
Answer:
A, C, and D are the correct answers.
Step-by-step explanation:
A) The total cost of the food, c, can be represented by the inequality c/6 < 8
C) The total cost of the food could be $36.
D) When graphed, the number line would be shaded to the left of the maximum value.
It's A because the 6 friends SPLIT the total cost which is c, and each person paid LESS than $8 dollars, not $8 and above. So it will look like, "total cost/6 people is less than 8" aka "c/6 < 8"
It's C because if each person paid less than $8 dollars, the total is anything under 48. (6 x 8 = 48, and 6 x 6 = 36, and 6 is less than 8.)
It's D because anything LESS than the max value could be the value to c/6. So anything to the left of 8, is less than 8, and anything to the right of 8, is greater than 8, and we want what is "< 8" less than 8 so it has to be to the left.
There ard 86,400 seconds in one day. If Mr. Liegel is at work for
28,800 seconds a day, how many seconds a day is he away from

Mike travels 13 miles per 2 hours on his bike.
How far does he travel in 6 hours?
How many hours does it take to 52 miles?
Answer:
It took Markus half an hour to drive home from work. He averaged 34 miles per hour. How far does Markus live from his work?
Solution
We are given that it takes 1/2 an hour for the trip. This is a time:
t = 1/2
We are given that he averages 34 miles per hour. This is a rate:
r = 34
We are asked how few he has traveled. This is a distance. We use the d=rt equation:
d = rt
= (34)(1/2)
= 17
Markus lives 17 miles from work.

Factor the trinomial. Factor out the GCF first.
5x^2y - 30xy^2 - 35y^3
Answer: [tex]5x^2y - 30xy^2 - 35y^3=5y(x+y)(x-7y)[/tex]
Step-by-step explanation:
GCF = Greatest common factor.
For example: 6 is the GCF of 12 and 18.
The given expression: [tex]5x^2y - 30xy^2 - 35y^3[/tex]
It can be written as
[tex]5x^2y - (5\times6)x( y\times y) - (5\times7)(y^2\times y)[/tex]
Taking out common factor [tex]5y[/tex] , we get
[tex]5y(x^2-6xy-7y^2)\\\\ =5y(x^2+xy-7xy-7y^2)\ \ [\because-6xy=xy-7xy]\\\\=5y(x(x+y)-7y(x+y))\\\\= 5y((x+y)(x-7y))\\\\=5y(x+y)(x-7y)[/tex]
Hence, [tex]5x^2y - 30xy^2 - 35y^3=5y(x+y)(x-7y)[/tex]

A student examines these books in random order, stopping only when a softcover book has been selected. One possible outcome is 5, and another is 213. (Enter your answers as a comma-separated list. Enter Ø for the empty set.)
Required:
a. List the outcomes in S
b. Let A denote the event that exactly one book must be examined. What outcomes are in A?
c. Let B be the event that book 5 is the one selected. What outcomes are in B?
d. Let C be the event that book 1 is not examined. What outcomes are in C?
Answer and Step-by-step explanation:
(a) Since the student have to stop when he gets to w softcover book, then the sample space should always stop at either 3 or 4 or 5. If the students examines the books randomly and stops at a softcover book, here are the possible ways he could carry this out,
S = {3, 4, 5, 13, 14, 15, 23, 24, 25, 123, 124, 125, 213, 214, 215}
2. Since only one book is to be examined then the student must check only one softcover book and end the examining. To do this, either he examines just 3 or 4 or 5. Therefore,
A = {3, 4, 5}
3. We need to pick the possibilities from the sample space that shows that the examining ended at book 5. Therefore,
B = {5, 15, 25, 125, 215}
4. We need to pick possibilities from the sample space that shows that book 1 was not examined. Therefore,
C = {3, 4, 5, 23, 24, 25}

Answer:
[tex]a=\sqrt{33}[/tex]
Step-by-step explanation:
When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know b and c we can plug that in to find out what a could be but we won't actually solve it.
[tex]a^2+b^2=c^2\\a^2+4^2=7^2\\a^2+16=49\\a^2=33\\\sqrt{a^2}=\sqrt{33}\\a=\sqrt{33}[/tex]
So a would equal whatever the square root of 33 is.

a college says it admits only people with sat scores among the top 10%. how high an sat score does it take to be g
Full question:
Suppose SAT scores among students are normally distributed with a mean of 500 and a standard deviation of 100.
If a college says it admits only people with sat scores among the top 10%. how high a sat score does it take to be eligible?
Answer and explanation:
To find where SAT score of student falls in the test given mean and standard deviation of scores, we can calculate: x-500/100 where x is number of SAT score of students
A sat score in the top 10% region would have a score better than 90% of other SAT scores. Therefore 0.90 has a z score of 1.28
We use algebra to find the score to be eligible thus:
1.28=x-500/100
x-500=128
x=128+500
x=628
Therefore to be eligible, a student needs to score at least 628, and be in the top 10% of scores

D. 97.6, θ = 24.2°
9514 1404 393
Answer:
C. 41.0, θ = 77.3°
Step-by-step explanation:
The sum is ...
5(8, 4) -3(-3, -4) +8(-5, 1) = (5·8-3(-3)+8(-5), 5·4-3(-4)+8·1)
= (40+9-40, 20+12+8) = (9, 40)
The magnitude is ...
√(9² +40²) = √1681 = 41
The angle is ...
arctan(40/9) ≈ 77.3°
The resultant magnitude and direction is 41∠77.3°.

A sample of 173 students using Method 1 produces a testing average of 88. A sample of 127 students using Method 2 produces a testing average of 53.5. Assume the standard deviation is known to be 12.22 for Method 1 and 13.59 for Method 2. Determine the 95% confidence interval for the true difference between testing averages for students Method 2.
Answer:
43 < μ₁ - μ₂ < 49
Step-by-step explanation:
Sample 1:
Mean x₁ = 88
Sample size n₁ = 173
Sample standard deviation s₁ = 12,22
Sample 2:
Mean x₂ = 53,5
Sample size n₂ = 127
Sample standard deviation s₂ = 13,59
CI 95 % α = 5% α = 0,05 α/2 = 0,025
We need to find:
( x₁ - x₂ ) - tα/2,v *√ (s₁²/n₁ ) + (s₂²/n₂) < μ₁ - μ₂ < ( x₁ - x₂ ) + tα/2,v *√ (s₁²/n₁ ) + (s₂²/n₂)
v = degree of fredom
v = [ ( s₁²/n₁ + s₂²/n₂)² / (s₁²/n₁)² /n₁-1 + (s₂²/n₂)²/n₂-1
v = [ (0,86 + 1,45 ) / 0,0043 + 0,017
v = 2,31 / 0,0213
v = 108
Then t 0,025, 108 from t table is: We will take v = 100
t = 1,984
Now
√ (s₁²/n₁ ) + (s₂²/n₂) = √ 0,86 + 1,43
√ 2,3 = 1,51
Then: CI:
(173 - 127 ) - 1,984*1,51 < μ₁ - μ₂ < ( 173 - 127 ) + 1,984*1,51
46 - 3 < μ₁ - μ₂ < 46 + 3
43 < μ₁ - μ₂ < 49

black. Slots 0 and 00 are both green.
Suppose that a player bets $1 on the color red. If the ball lands in a red slot, the player gets their initial $1 back
plus a payout of $1. If the ball doesn't land in a red slot, they lose their $1 bet. Let X = the player's net gain

Answer:
1) y = -1
2) y = 3
3) y = 5
4) y = 9
Step-by-step explanation:
1) when x = -2
y = 2x + 3
y = 2(-2) +3
y = -1
2) when x = 0
y = 2x + 3
y = 2(0) +3
y = 3
3) when x = 1
y = 2x + 3
y = 2(1) +3
y = 5
4) when x = 3
y = 2x + 3
y = 2(3) +3
y = 9
