Step-by-step explanation:
Determine if this is a function.
I did the vertical line test, but I'm still a bit confused.
Answer: This is not a function
Why not?
The input x = 2 leads to more than one output. In this case, it leads to y = 20 and y = 40 simultaneously. This is the reason why we don't have a function. A function is only possible if each input x leads to exactly one y output.
Put another way: we cannot have x repeating any values if we want a function.
Side note: We could have y repeat however. So it's possible to have a function with the two points (1,5) and (3,5).

Determine the distance between L(1, 4, 7) and M(2, 9, 8) on a three-dimensional plane.
XY = √(x2 – x, )²+ (y2 – yı)2 + (x2 – 21)2
Answer:
Distance LM = 5.20 unit (Approx.)
Step-by-step explanation:
Given coordinates;
L(1, 4, 7) and M(2, 9, 8)
Find:
Distance LM
Computation:
Distance between three-dimensional plane = √(x2 - x1)² + (y2 - y1)² + (z2 - z1)²
Distance LM = √(2 - 1)² + (9 - 4)² + (8 - 7)²
Distance LM = √(1)² + (5)² + (1)²
Distance LM = √1 + 25 + 1
Distance LM = √27
Distance LM = 3√3 unit
Distance LM = 3(1.732)
Distance LM = 5.196
Distance LM = 5.20 unit (Approx.)

The best price for her to purchase ice cream is given as follows:
D. $49.60 / five gallon tub.
How to obtain the best price?The best price is obtained applying the proportions in this problem, dividing the price by the volume of the cartoon/tub, in ounces.
For item a, the price per ounce is calculated as follows:
3.99/24 = $0.16625 per ounce.
The ratios for the remaining items are given as follows:
Quarts to ounces: 1 quart = 32 ounces.Gallons to ounces: 1 gallon = 128 ounces.Hence the prices for items b, c and d are given as follows:
Item b: 4.8/32 = $0.15 per ounce.Item c: 11/128 = $0.085 per ounce.Item d: 39.6/(5 x 128) = $0.06 per ounce.Due to the lower cost per ounce, the option D represents the best option for her to purchase ice cream.

38) Your bank account has$82in it when you write checks for$54,$35, and$15. You then deposit $35and $42. How much is in the account? Are you overdrawn
the answer is 55 can you show me how to get that answer.
If you have $82 in your bank account and you write checks for $54, $35, and $15, then the total amount you have written in checks is $54 + $35 + $15 = $104.
So the remaining balance is $82 - $104 = -$22, which means you are now overdrawn.
After you deposit $35 and $42, the new balance will be $82 - $22 + $35 + $42 = $155
So after the deposit, the account balance is $155
It is important to keep track of your bank account balance, if you do not have enough funds in the account and the check you wrote is cashed the bank will bounce the check and incur additional fees.

Find the value of b such that the system of equations does not have a solution.
bx - 20y = -11
-6x – 15y = 11
b=
b= 8
Step-by-step explanation:
If we rewrite the 2nd equation, it becomes
15y = -6x - 11 ---> y = (-2/5)x - (11/15)
In order for this system of equations to have no solution, they must have the same slope, i.e., they're parallel to each other. So rewriting the 1st equation,
20y = -bx + 11
---> -b/20 = -0.4 or b = 8
The product of some number and 40 is 2600
Answer:
65
Step-by-step explanation:
To find the second factor of a multiplication problem with only the answer and the first factor, divide the answer by the first factor.
[tex]2600/40= 65.[/tex]
Therefore, 40 × 65 = 2600.
If the rectangular fish tank below is completely filled with water, and the 900 cubic centimeters are poured out, how high will the water
Answer:
The high of the water is 2 cm.
Step-by-step explanation:
The equation of this volume is:
[tex]V=45*10*x[/tex]
We know that the volume is 900 cm³. So we just need to put this value in the above equation and solve it for x, which is the height.
[tex]900=45*10*x[/tex]
[tex]900=450*x[/tex]
[tex]x=\frac{900}{450}[/tex]
[tex]x=\frac{900}{450}[/tex]
[tex]x=2\: cm[/tex]
Therefore, the high of the water is 2 cm.

-38 + -12x < -200
Answer:
-38 - 12x > -200
x = 13.5 min
Step-by-step explanation:
let x = minutes of the dive
-38 ft - 12 ft/min(x) > -200 ft
-12 ft/min(x) < -162 ft
x > -162/-12 **flip the inequality when you divide by a (-) number
x > 13.5 min
Starting at -38 ft, he has to dive longer than 13.5 minutes to go deeper than -200 ft at a rate of -12 ft/min

The following table shows the scores of three Redbirds and the Rockets in the first six games of the basketball season.
Part A:
Which team had the higher average (mean) score? What was it?
Part B:
Which team had the higher median score? What was it?
Part C: Which team had the higher range? What was it?
PLEASE don’t answer if you don’t know the answer. Whoever answers correctly will get Brainliest :)
Answer:
Step-by-step explanation:
1) mean: sum the values and divide for how many they are
Red birds: (87+94+99+85+106+111)/6 = 97
Rockets : (93+107+87+89+108+92)/6 = 96
the Red birds have the higher mean, that is 97
2) median
set the numbers from the least to the greatest and check the number in the middle
Red birds: 85, 87, 94, 99, 106, 111
there are two numbers in the middle, so we have to added up them and divide the result by two
median = (94 + 99)/2 = 96,5
Rockets = 87, 89, 92, 93, 107, 108
median = (92+93)/2 = 92,5
the Red birds have the higher median, that is 96,5
3) range: difference between the highest and the lowest value
Red birds = 111 - 85 = 26
Rockets = 108 - 87 = 21
the Red birds have the highest range, that is 26

If the perimeter of the triangle is 64 units, then the length of the side PR is 24 units.
What is a Triangle?This is referred to as a three-sided polygon that consists of three edges and three vertices and the longest side is referred to as the hypotenuse.
The perimeter of a triangle is the sum of all the sides which is:
P = a + b + c
64 = 3x +4x - 1 + x + 1
64 = 8x
x = 64/8 = 8 units
Therefore the length of side PR is :

A sanitation department is interested in estimating the mean amount of garbage per bin for all bins in the city. In a random sample of 46 bins, the sample mean amount was 49.41 pounds and the sample standard deviation was 3.99 pounds. Construct a 92.7% confidence interval for the expected amount of garbage per bin for all bins in the city. Answer to 3 decimals (a) What is the lower limit of the 92.7% interval
Answer:
The 92.7% confidence interval for the expected amount of garbage per bin for all bins in the city is between 48.135 pounds and 50.685 pounds. The lower limit is 48.135 pounds.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 46 - 1 = 45
92.7% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 45 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.927}{2} = 0.9635[/tex]. So we have T = 2.1437
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.1437\frac{3.99}{\sqrt{45}} = 1.275[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 49.41 - 1.275 = 48.135 pounds
The upper end of the interval is the sample mean added to M. So it is 49.41 + 1.275 = 50.685 pounds.
The 92.7% confidence interval for the expected amount of garbage per bin for all bins in the city is between 48.135 pounds and 50.685 pounds. The lower limit is 48.135 pounds.

Given L || M find the value of unknown angles in each of the following figures
Answer:
Angle x = 120 degrees
Angle y = 60 degrees
Step-by-step explanation: Angle x has to be equivalent to the 120 degree angle that is already given since lines l and m are parallel as well as lines p and q. To find angle y, you must realize that angles x and y are supplementary angles, so their sum is 180 degrees. Since we now know that angle x is 120 degrees, you must subtract 120 from 180 in order to find the value of angle y: 180 - 120 = 60 degrees. I'm sure that there are other methods to figuring this question out, but this is how I did it.
