Answer:
-31, 9, 1, 5, 37
Step-by-step explanation:
f(x) = -2(-2)^2 + 1
f(x) = 4^2 + 1
f(x) = 8+1
f(x) = 9
f(x) = -2(0)^2 +1
f(x) = 0^2 + 1
f(x) = 0 + 1
f(x) = 1
f(x) = -2(1)^2 + 1
f(x) = -2^2 + 1
f(x) = 4+1
f(x) = 5
f(x) = -2(3)^2 + 1
f(x) = -6^2 + 1
f(x) = 36+1
f(x) = 37

provide an appropriate response. the owner of a computer repair shop has determined that their daily revenue has mean $7200 and standard deviation $1200. the daily revenue totals for the next 30 days will be monitored. what is the probability that the mean daily revenue for the next 30 days will be less than $7000?
Answers
The probability that the mean daily revenue for the next 30 days will be less than $7000 IS 0.7333
Standard deviation of the sample is equal to the population's Standard Deviation divided by the square root of the sample's item count.
Standard Deviation of the sample = [tex]1200/\sqrt{30} = 219.09[/tex]
SD of the sample is equal to the population's Standard Deviation divided by the square root of the sample's item count.
To reach a result of 300, divide 7500 by the mean of 7200. 300 divided by the sample's SD (219.09) yields a result of 1.37. A z-table search for +1.37 returns a result of 0.9147. Accordingly, there is a 0.9147 percent chance that the average daily revenue over the following 30 days will be less than $7500.
To get a result of -200, divide 7000 by the mean of 7200. Divide -200 by the sample's standard deviation (219.09), and you'll get -0.91. search for -0.91 in a z-table receive a score of 0.1814. The likelihood that the mean daily revenue for the following 30 days would be less than $7000 is therefore 0.1814.
Simply subtract the likelihood that the mean daily revenue is less than $7000 (0.1814) from the likelihood that the mean daily revenue is less than $7500 (0.9147) to arrive at the probability that the mean daily revenue for the upcoming 30 days will be between $7000 and $7500. This yields a result of 0.7333.
There is a 73.33% chance that the average daily income over the following 30 days will be less than $7000.

a) The median is the middle value. It separates the data set in two. To find the median we have to put the data in order, from least to greatest:
[tex]44,49,53,54,58,74,74,74,80[/tex]The number of data is odd, this means that the median will be one of the values of the data set and not a mean between two of them. If there are 9 values, the median is the 5th value - so we have 4 values to the left and 4 values to the right.
The first 4 values are 44,49,53,54, so the median is 58.
b) The mean is the sum of all values of the data set divided by the amount of data:

14. In exercise 13, suppose grapes cost
$2.35 per pound, oranges cost $0.99 per
pound, and apples cost $1.65 per pound.
Estimate how much Adrian paid for all
the fruit.
Answers
Assume grapes cost $2.35 per pound, oranges cost $0.99 per pound, and apples cost $1.65 per pound in exercise 13. Adrian paid a total of $5 for the fruits.
What is Estimation?Calculations are made easier and more realistically when a number is estimated, which is a plausible estimation of its true value.To estimate something is to approximate it as accurately as possible.To acquire a quick and approximate response, this is obtained by rounding off the values used in the calculation. Rounding integers to the closest whole number is the simplest method for estimating. Rounding off makes getting a rough answer quicker. Koel, for instance, makes a 3950 monthly deposit toward the cost of her new home. This value can be rounded out to 4000 to make the calculation easier. To round a number, determine its nearest required digit. To avoid working with fractions or decimals, numbers are frequently rounded to the next whole number.Therefore,
The cost of Grapes = $2.35 per pound
The cost of Oranges = $0.99 per pound
The cost of Apples = $1.65 per pound
If Adrian purchased one pound of each fruit,
He paid:
$2.35 + $0.99 + $1.65 = $4.99 = $5 (Approx.)
So, Adrian paid $5 in total for the fruits.

A shipping box has a volume of 1,000 cubic inches. What is the length of one side of the box?
Answers
The length of one side of the box is 10 inches.
How to find the volume of a cube?Suppose that: The side length of the considered cube is L units.
Then, we get the Volume of that cube = L³ cubic units.
The volume of a cube is of the form V = L³, where L is the side length.
Given that the shipping box has a volume of 1,000 cubic inches.
Here, we know the volume V, but not the measure of length. So, we can plug in the value 1000 for V and solve for L:
1000 = L³

six distinct positive integers are randomly chosen between and , inclusive. what is the probability that some pair of these integers has a difference that is a multiple of ?
Answers
Answer:
So the probability of this happening is exactly 1 - it must be true
Step-by-step explanation:
If we calculate modulo(5) for each of the six numbers (the integer remainder after dividing by 5), we will get six values from 0 to 4.
By the pigeonhole principle, since there are 6 numbers and only 5 possible values, at least two must share the same value modulo 5. Pick two of those, say x and y, in which case x mod 5 = y mod 5, therefore (x - y) mod 5 = 0. In other words, their difference is a multiple of 5.
So the probability of this happening is exactly 1 - it must be true

What is the congruency of triangles?Triangle congruence: If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent. Slide, rotate, flip, and turn these triangles to create an identical appearance. They are in alignment with one another when moved. Therefore, if all three sides of two triangles are the same, then the triangles are said to be congruent. If we have a side, an angle between the sides, and then another side that is congruent, we know they are congruent. In other words, side, angle, side.So, to prove that △PQR ≅ △STU:
∠P = ∠S (Given)PQ = ST (Option B)∠Q = ∠T (Option D)So, with these three conditions, △PQR ≅ △STU is under ASA condition.

Answers
Answer:
y = 3
Step-by-step explanation:
20 = 4 (y + 8) - 8y
20 = 4y + 32 - 8y
20 - 32 = 4y - 8y
-12 = -4y
-4y = -12
-4y/-4 = -12/-4
y = 3
To check
20 = 4 (y + 8) - 8y
20 = 4 (3 + 8) - 8(3)
20 = 12 + 32 - 24
20 = 44 - 24
20 = 20
Correct~
Answer: y = 3
Step-by-step explanation:
1. Distribute the 4 to the terms in the parenthesis.
20 = 4y + 32 - 8y
2. Combine like terms (those containing y).
20 = -4y + 32
3. Isolate terms with y by subtracting 32 from both sides.

Answers
Elijah put $53 in the Bank in the first week .
In the question ,
it is given that Elijah put (2x+3) in the first week .
In the second week Elijah put double the first week savings
that means second week deposit = 2*(2x+3) = 4x+6
in the third week he doubled the amount that was in the bank ,
which means third week deposit = 2*(first week + second week deposit)
= 2*(2x+3+4x+6)
Also given that total amount in the bank = $477
total amount = first week + second week + third week deposit
substituting the values we get
477 = (2x+3) + (4x+6) + 2*(2x+3+4x+6)
477 = 2x+3+4x+6+4x+6+8x+12
477 = 18x + 27
18x = 477-27
18x = 450
x = 450/18
x = 25
the amount deposited in the first week = 2x+3
= 2(25)+3
= 50+3 = $53
Therefore , Elijah put $53 in the Bank in the first week .
The given question is incomplete , the complete question is

Answers
Note that a line whose equation is in the form :
[tex]y=mx+b[/tex]has a slope of m

Slope is also equal to rise/run :
[tex]m=\frac{\text{rise}}{\text{run}}[/tex]where rise is the number of vertical units between two points and run is the number of horizontal units between two points.
Note also that upward and right movement is positive, downward and left movement is negative.
From the figure, the vertical units between two given points is 3 units upward, so this is positive.
The horizontal units between them is 2 units to the right which is also positive.
The slope will be :

y-intercept is the point where the line intersects the y-axis.
