Alright, within the image, the triangles ABC and TUV are congruent. With this, the following is true: AB ≅ TU, BC ≅ UV, and CA ≅ VT because the order and their sides between the two triangles is shared.
With this, BC is ≅ to UV. Now, just set the two equations equal to each other:
9x+2=8x+9
9x=8x+7
x=7
Now, we've got x, though it needs to be plugged back into side BC for the final answer

Chandra needs to make 3 gallons of punch. How many cups of frozen strawberries are needed? Use the drown-down menus to complete the answer.
The number of cups of frozen strawberries that are needed to make 3 gallons of punch is equal to 48 cups.
How to calculate the cups of frozen strawberries needed?In this exercise, you're required to determine the number of cups of frozen strawberries that are needed to make 3 gallons of punch. Thus, we would apply direct proportion.
Note: There are 16 cups of frozen strawberries in a gallon.
By direct proportion:
16 cups = 1 gallon
X cups = 3 gallons
Cross-multiplying, we have:
X = 16 × 3
X = 48 cups of frozen strawberries.

each saturday, tina mows lawns to earn extra money which she puts into a savings account. the graph shows the balance of tina’s savings accounts over the first six weeks of mowing lawns. according to this pattern, how much will tina have in her account after 15 weeks of mowing lawns?
Answer:
$255
Step-by-step explanation:
First, we need to generate an equation in slope-intercept form, y = mx + b, that represents the graph. To do this, we need to find b = initial value (y-intercept) and m = slope (money she puts in her account each week).
x = number of weeks
y = balance ($)
✔️Slope (m) = change in y/change in x
Using two points on the line, (1, 45) and (2, 60),
Slope (m) = (60 - 45)/(2 - 1) = 15/1
m = 15
✔️To find b, substitute (x, y) = (1, 45) and m = 15 into y = mx + b.
45 = 15(1) + b
45 = 15 + b
45 - 15 = b
30 = b
b = 30.
✔️To write the equation, substitute m = 15 and b = 30 into y = mx + b
y = 15x + 30
✔️To determine how much Tina will have in her account (y) after 15 weeks (x) of mowing, substitute x = 15 into y = 15x + 30:
y = 15(15) + 30
y = 225 + 30
y = 2
Therefore, Tina will have $255 in her accounts after 15 weeks of mowing lawns.

Answer:
Socio 1 recibirá Q. 10,690, Socio 2 recibirá Q. 5,345, Socio 3 recibirá Q. 13,655, Socio 4 recibirá Q. 11,285 y Socio 5 recibirá Q. 14,255.
Step-by-step explanation:
Dado que en una sociedad participan 5 socios, colocando todos capitales iguales, lo único que el primer socio estuvo 1 año y medio, el segundo 9 meses, el tercero 5 meses mas que el primero, el cuarto 1 año 7 meses y el quinto 2 años, para determinar cuánto le toca a cada socio de una utilidad de Q. 55,230.00 se deben realizar los siguientes cálculos:
Socio 1 = 1.5 años
Socio 2 = 0.75 años
Socio 3 = 1.916 años
Socio 4 = 1.583 años
Socio 5 = 2 años
Total = 1.5 + 0.75 + 1.916 + 1.583 + 2 = 7.75
Socio 1 =
7.75 = 100
1.50 = X
1.50 x 100 / 7.75 = X
19.35 = X
55,230 x 0.1935 = 10,690
Socio 2 =
7.75 = 100
0.75 = X
0.75 x 100 / 7.75 = X
9.68 = X
55,230 x 0.0968 = 5,345
Socio 3 =
7.75 = 100
1.916 = X
1.916 x 100 / 7.75 = X
24.72 = X
55,230 x 0.2472 = 13,655
Socio 4 =
7.75 = 100
1.583 = X
1.583 x 100 / 7.75 = X
20.43 = X
55,230 x 0.2043 = 11,285
Socio 5 =
7.75 = 100
2 = X
2 x 100 / 7.75 = X
25.81 = X
55,230 x 0.2581 = 14,255
Por lo tanto, Socio 1 recibirá Q. 10,690, Socio 2 recibirá Q. 5,345, Socio 3 recibirá Q. 13,655, Socio 4 recibirá Q. 11,285 y Socio 5 recibirá Q. 14,255.

Given the following formula, solve for l.
Answer: Option C
l = (P - 2b)/2
Step-by-step explanation:
From P = 2(l + b)
Divide both sides by 2;
P/2 = 2(l + b)/2
P/2 = l + b
l + b = P/2
Make l the subject of formula;
l = (P/2) - b
l = (P - 2b)/2

A non-profit organization plans to hold a raffle to raise funds for its operations. A total of 1,000 raffle tickets will be sold for $1.00 each. After all the tickets are sold, one ticket will be selected at random and its owner will receive $50.00. The expected value for the net gain for each ticket is -$0.95. What is the meaning of the expected value in this context?
A. The ticket owners lose an average of $0.05 per raffle ticket.
B. The ticket owners lose an average of $0.95 per raffle ticket.
C. Each ticket owner will lose $0.95 per raffle ticket.
D. A ticket owner would have to purchase 19 more tickets for the expected value of his or her net gain to increase to $0.00.
E. A ticket owner has a 95 percent chance of having a ticket that is not selected.
Answer:
The answer is "Option b".
Step-by-step explanation:
In the given question, 1000 ticket were sold for [tex]\$1[/tex] and the owner who receives tickets which are randomly chosen that wins [tex]\$50[/tex].
[tex]Net\ profit = 1000\times 1-1\timesv 50 = \$950\\\\Net \ profit \ for\ ticket = \frac{\$950}{1000} = \$0.95[/tex]
The probability in which each ticket owners win [tex]= 0.001[/tex]

An orange juice manufacturer advertises a new orange juice product that contains 50% less sugar. This new product is expected to increase profits substantially because they create the 50% less sugar product by replacing 50% of the juice with water while selling it for the same price. An inspector wants to investigate whether the actual percentage of water in the product is within 5% of the intended 50%.
He selects a random sample of 500 containers of orange juice and determined the percentage of each that is water. He plans to conduct a significance test at the a = 0.01 level to see if there is convincing evidence that the proportion of water added is different from 0.50. What is the probability that the inspector makes a Type I error?
(A) 0.01
(B) 0.05
(C) 0.10
(D) 0.45
(E) 0.50
Answer: A. 0.01
Step-by-step explanation:
Type I error are refered to as false positives and it means that when a statistically significant difference is validated by the researcher even though the results aren't statistically significant.
Type I error is when one rejects the null hypothesis even though it's actually true. In this case, the inspector rejects the hypothesis which was that the proportion of water that is contained the product is 0.5.
The probability of type 1 error will then be equal to the hypothesis level of significance and this will be 0.01.

Consider a sample with data values of 27, 25, 20, 15, 30, 34, 28, and 25. Compute the range, interquartile range, variance, and standard deviation (to a maximum of 2 decimals, if decimals are necessary).
Range:
Interquartile range:
Variance:
Standard deviation:
Range: 19
Interquartile range: 6.5
Variance: 44.86
Standard deviation: 6.70
Step-by-step explanation:
Given set:
27, 25, 20, 15, 30, 34, 28, 25.
(i) Range is the difference between the largest value and smallest value in a given data.
In the data above, the;
largest value = 34
smallest value = 15
Range = largest - smallest
Range = 34 - 15
Range = 19
(ii) Interquartile range is the difference between the median (Q₁) of the lower half of the given data, and the median (Q₃) of the upper half of the given data. i.e Q₃ - Q₁.
This should be done after ordering the given data in ascending order.
Ordering the above data gives:
15, 20, 25, 25, 27, 28, 30, 34
In the data above;
lower half = 15, 20, 25, 25
upper half = 27, 28, 30, 34
Find median (Q₁) of the lower half
Since there are even number of data, the median is the average of two middle numbers (20 and 25) i.e.
Q₁ = [tex]\frac{20+25}{2}[/tex] = [tex]\frac{45}{2}[/tex] = 22.5
Find median (Q₃) of the upper half
Since there are even number of data, the median is the average of two middle numbers (28 and 30) i.e.
Q₃ = [tex]\frac{28+30}{2}[/tex] = [tex]\frac{58}{2}[/tex] = 29
Interquartile range = Q₃ - Q₁
Interquartile range = 29 - 22.5
Interquartile range = 6.5
(iii) Variance is the measure of variability of a given set of data. It is calculated by following these steps:
=> First find the mean of the data by summing the numbers and dividing by the number of numbers. i.e
mean(x) = [15 + 20 + 25 + 25 + 27 + 28 + 30 + 34] / 8
mean(x) = [204] / 8
mean(x) = 25.5
=> Next, get the mean deviation by subtracting the mean from each individual value in the given set of data. i.e
15 - 22.5 = -7.5
20 - 22.5 = -2.5
25 - 22.5 = 2.5
25 - 22.5 = 2.5
27 - 22.5 = 4.5
28 - 22.5 = 5.5
30 - 22.5 = 7.5
34 - 22.5 = 11.5
=> Next, find the square of each of the results obtained above. i.e
(-7.5)² = 56.25
(-2.5)² = 6.25
(2.5)² = 6.25
(2.5)² = 6.25
(4.5)² = 20.25
(5.5)² = 30.25
(7.5)² = 56.25
(11.5)² = 132.25
=> Next, add all the results above together as follows;
56.25 + 6.25 + 6.25 + 6.25 + 20.25 + 30.25 + 56.25 + 132.25 = 314
=> Now, obtain the variance by dividing the result above one less than the number of numbers.
The number of numbers is 8. One less than this gives 7.
Therefore,
Variance = 314 / 7
Variance = 44.86
(iv) Standard deviation is the measure of how the numbers in the given data are spread out. It is calculated as the square root of variance.
Therefore,
Standard deviation = √variance.
Variance has been calculated above.
Standard deviation = √44.86
Standard deviation = 6.70

Answer:
<COB = 50°
Step-by-step explanation:
We can say that m<AOC + m<COD + m<DOB = 180° because the three mentioned angles form a straight line. We can substitute to get:
3x + 94 + x + 18 + 2x - 4 = 180
Then, we can combine like terms:
6x + 108 = 180
6x = 72
x = 12
We can see that m<COB is the sum of m<COD and m<DOB. We can wrote an equation to model the situation:
m<COB = m<COD + m<DOB
m<COB = x + 18 + 2x - 4
m<COB = 3x + 14
We have the value of x, so we can substitute that in:
<COB = 3(12) + 14
<COB = 36 + 14
<COB = 50°
