Step-by-step explanation:
Use the graph of g to solve.
Find g(-16)
Answer:
g(-16) = 6
Step-by-step explanation:
We want the value of the function when x = -16
The function is constant from x = -8 to the left. The value is 6
g(-16) = 6
Answer:
g(-16) = 6
Step-by-step explanation:
The upper horizontal line with an arrow to the left means that the value of function g remains at 6 from x = -8 as it approaches negative infinity. Since -16 is in the interval from -8 to -infinity, then
g(-16) = 6

Jason and his brother each have the equal probability of being randomly selected to wash dishes after dinner. Jason wants to simulate the probability that more than 4 evenings will go by without him having to wash the dishes after dinner. He decides to conduct a simulation by flipping a quarter, with heads representing an evening where he washes dishes after dinner and tails representing an evening of not doing dishes after dinner. He keeps flipping until he flips heads and records the number of flips that were needed. For example, if two flips are needed to get heads, this indicates that he washes dishes on the second evening. He repeats this 50 times and records the data on the table below Number of flips until getting heads: 1,2,3,4,5,6,7,8 frequency: 21,18,4,4,2,0,0,1 Based on the results of the simulation, what is the probability that more than 4 evenings will go by without Jason having to wash dishes after dinner? [blank] %
Answer:
The probability that more than 4 evenings will go by without Jason having to wash dishes after dinner is 0.06.
Step-by-step explanation:
We are given that Jason wants to simulate the probability that more than 4 evenings will go by without him having to wash the dishes after dinner.
He repeats this 50 times and records the data on the table below;
Number of flips until getting heads Frequency
1 21
2 18
3 4
4 4
5 2
6 0
7 0
8 1
Total 50
Now, we have to find the probability that more than 4 evenings will go by without Jason having to wash dishes after dinner.
This will happen only when the Number of flips until getting heads is 5, 6, 7 or 8 as only then Jason will have more than 4 evenings go by without washing dishes after dinner.
So, required probability = [tex]\frac{2}{50}+\frac{0}{50}+\frac{0}{50}+\frac{1}{50}[/tex]
= [tex]\frac{3}{50}[/tex] = 0.06
A train goes at a constant speed. If it covers 150 miles in 2/1 2 hours,
e
How long would it take for that train to cover 270 miles?
Answer:
x =4.5 hours
Step-by-step explanation:
We can use ratios to solve
150 miles 270 miles
--------------- = --------------
2.5 hours x miles
150 *x = 270*2.5
Divide each side by 150
150x/150 = 270*2.5/150
x =4.5 hours
Customers can pick their own apples at the Happy Apple Farm. They pay $5
to enter the farm and S2.50 per pound for the apples they pick. Write an
equation to model the total cost, y, for x pounds of apples.
O A. y = 5x + 25
B. y = x(2.5 + 5)
c. y = 2.5x + 5
O D. y = 2.5(x + 5)
Answer: C
Step-by-step explanation:
For this problem, we know that customers already have to pay $5 just to enter the farm. The $5 is basically a flat fee. Our equation would be:
y=5+____
Now, we know that the apples cost $2.50 per pound. Our final equaiton would be:
y=5+2.5x

Find positive integer x, if 1+2+3 +...+x=120.
Answer:
x = 15
Step-by-step explanation:
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 +13 + 14 + 15 = 120
The number x is a positive integer.
Value of positive integer [tex]x[/tex] is equals to [tex]15[/tex].
What is integers?" Integers is defined as collection of whole numbers and negative numbers."
Formula used
Sum of first [tex]'n'[/tex] natural numbers
[tex]S_{n} = \frac{n(n + 1)}{2}[/tex]
According to the question,
Given positive integers,
[tex]1 + 2 + 3 + ......... + x =120[/tex]
Substitute the value in the formula to get sum of positive integers,
[tex]\frac{x(x+ 1)}{2}=120\\\\\implies x^{2} +x =240\\\\\implies x^{2} + x-240 =0\\\\\implies x^{2} +16x-15x -240=0\\\\\implies x (x+16) -15 (x+16) =0\\\\\implies (x+ 16) (x-15) =0\\\\\implies x = -16 or x =15[/tex]
[tex]'x'[/tex] is a positive integer. [tex]x=-16[/tex] is not possible.
Hence, Value of positive integer [tex]x[/tex] is equals to [tex]15[/tex].

Simplify i^12
A. -1
B. -i
C. i
D. 1
Answer:
D
Step-by-step explanation:
Answer:
D. 1.
Step-by-step explanation:
We know that the powers of the imaginary constant, i, follow a certain pattern.
i^1 = i, i^2 = -1, i^3 = -i, i^4 = 1.
Every 4 powers, the result cycles back to the original i. This is because there are only 4 unique digits that result from raising i to various powers.
To figure a higher power, such as 12, we need to take the remainder of the power when divided by 4 (the amount of unique answers), to simplify it to the original 4 powers.
So when you have i^12 power, the remainder is 0. This is because 4 is a factor of 12. As a result, we can simplify this to i^8, and therefore i^4, which equals 1.

Which is the equation for a sphere with the center (8,-6,6) and radius 6?
Answer:
(x - 8)² + (y+6)² + (z-6)²= 36
Step-by-step explanation:
To find the equation for a sphere with the center (8,-6,6) and radius 6, we will follow the steps below;
first write down the standard equation of a sphere:
(x - h)² + (y-k)² + (z-l)²= R²
where h, k and l are the center and R is the radius
From the question given, h = 8, k =-6 l=6 and R=6
we can now substitute the values into the formula
(x - h)² + (y-k)² + (z-l)²= R²
(x - 8)² + (y+6)² + (z-6)²= 6²
(x - 8)² + (y+6)² + (z-6)²= 36
Therefore, the equation for a sphere with the center (8,-6,6) and radius 6 is
(x - 8)² + (y+6)² + (z-6)²= 36
15−x+y=14−(−x−y) help plz
Answer:
[tex]x=0.5[/tex]
[tex]y=anything[/tex]
Step-by-step explanation:
15−x+y=14−(−x−y)
15-x+y=14+x+y
Subtract 14 from both sides
1-x+y=x+y
Subtract y from both sides
1-x=x
Add x to both sides
1=2x
2x=1
Divide both sides by 2
x=0.5
18. The equations 6x + 5y 300 and 3x + 7y = 285

the cost for each snack gift basket and y represents
the cost for each chocolate gift basket, what is the
cost for each chocolate gift basket?
A) $20 B) $25 C) $30 D) $54
PLS HELP ME ASAP!
Answer: The cost for each chocolate gift basket is b)$25.
Step-by-step explanation:
Hi, the correct equations are:
6x + 5y =300
3x + 7y = 285
So, if we multiply the second equation by 2, and subtract the first equation to the second equation:
6x +14 y= 570
-
6x +5y =300
_________
9y = 270
Solving for y:
y = 270/9
y = 30
Substituting y=30 on any equation:
6x + 5y =300
6x + 5(30) =300
Solving for x (cost for each chocolate gift basket)
6x+150 =300
6x =300-150
6x = 150
x =150/6
x = $25

2/9 of the 45 marbles must be red.
2/9 * 45 = 10
Answer:
10
Step-by-step explanation:
let's make the number of red marbles x
so probability of getting red marbles is x/45
so;.
[tex] \frac{x}{45} = \frac{2}{9} [/tex]
[tex] 45 \times \frac{x}{45} = \frac{2}{9} \times 45[/tex]

The drama club is selling tickets to their play to raise money for the show's expenses.
Each student ticket sells for $4.50 and each adult ticket sells for $8. The auditorium
can hold no more than 84 people. The drama club must make at least $560 from
ticket sales to cover the show's costs. If 29 student tickets were sold, determine all
possible values for the number of adult tickets that the drama club must sell in order
to meet the show's expenses. Your answer should be a comma separated list of values.
If there are no possible solutions, submit an empty answer.
Answer:
The minimum number of adult tickets required to be sold = 54
Step-by-step explanation:
Hello,
In this question, we have several variables which might confuse us here, so I'll have to break it down bit by bit.
The drama club must make a sale of $560 so as to cover cost for the event.
The seat capacity of the hall = 84
Cost of tickets for adult = $8
Cost of tickets for students = $4.50
Total number of students sold = 29
Let the number of adult ticket required = x.
(4.50 × 29) + (8 × x) = 560
130.5 + 8x = 560
8x = 560 - 130.5
8x = 429.5
Divide both sides by 8
X = 429.5 / 8
X = 53.6 approximately 54.
Minimum required number of adult tickets to be sold is 54.
(29 × 4.50) + (54 × 8) = $130.5 + $432 = $562.5

{54,55}

What is the sum of the tens? Enter your answer in the box.
Answer:
[tex]Sum = 100[/tex]
Step-by-step explanation:
Given
468 and 241
Required
Sum of the Tens
Breaking 468 to smaller bits; we have
Hundred = 400
Tens = 60
Units = 8
Breaking 241 to smaller bits; we have
Hundred = 200
Tens = 40
Units = 1
The question requests for the sum of the Tens;
The sum of the tens goes thus;
[tex]Sum = Tens_{468} + Tens_{241}[/tex]
[tex]Sum = 60 + 40[/tex]
[tex]Sum = 100[/tex]
Hence, the sum of tens of 468 and 241 is 100
