Of the 250 total shirts about, the quantity of shirts that should be red would be = 125.
How to calculate the quantity of shirts that are red.?The total quantity of shirts that was ordered by Mr. Torres = 250 school t-shirts
The total quantity of red shirt selected at random = 5
The total quantity of blue shirt selected at random = 13
The total quantity of grey shirt selected at random = 12
Total selected at random = 30
Now if 5 red shirts = 30
X red shirts = 250
make X the subject of formula;
X = 15× 250/30
X = 3750/30
X = 125 red shirts.

As a promotional feature, a store conducts a weekly raffle. During any week, 40% of the customers who turn in one or more tickets do not bother to turn in tickets the following week. On the other hand, 30% of the customers who do not turn in tickets will turn in one or more tickets the following week. Find and interpret the steady matrix for this situation.
Answers
Given statement solution is :- Interpreting the steady matrix:
The value 0.6 in the top left cell represents the proportion of customers who turn in tickets this week and will turn in tickets again next week.
The value 0.3 in the top right cell represents the proportion of customers who turn in tickets this week but will not turn in tickets next week.
The steady matrix provides a snapshot of the probabilities of transitioning between the two states (turning in tickets or not turning in tickets) in the long run, assuming these probabilities remain constant over time.
To analyze the steady matrix for this situation, let's consider the two groups of customers: those who turn in tickets and those who do not turn in tickets.
Let's denote the proportion of customers who turn in tickets as X and the proportion of customers who do not turn in tickets as Y.
According to the given information:
40% of the customers who turn in tickets do not turn in tickets the following week. This means that 60% of the customers who turn in tickets will turn in tickets again the following week.
30% of the customers who do not turn in tickets will turn in tickets the following week. This means that 70% of the customers who do not turn in tickets will continue not turning in tickets the following week.
Based on these percentages, we can construct the steady matrix:
java
Copy code
| Customers turning in tickets (X) | Customers not turning in tickets (Y) |
----------|----------------------------------|--------------------------------------|
Next week 0.6 0.3
This week 0.4 0.7
Interpreting the steady matrix:
The value 0.6 in the top left cell represents the proportion of customers who turn in tickets this week and will turn in tickets again next week.
The value 0.3 in the top right cell represents the proportion of customers who turn in tickets this week but will not turn in tickets next week.
The value 0.4 in the bottom left cell represents the proportion of customers who do not turn in tickets this week but will turn in tickets next week.
The value 0.7 in the bottom right cell represents the proportion of customers who do not turn in tickets this week and will continue not turning in tickets next week.
These values describe the transition probabilities between the two customer groups. For example, if there are 100 customers in total, 60 of them will turn in tickets next week, and 40 of them will not. Similarly, 30 customers who turn in tickets this week will not do so next week, while 70 customers who do not turn in tickets this week will continue to not turn them in next week.
The steady matrix provides a snapshot of the probabilities of transitioning between the two states (turning in tickets or not turning in tickets) in the long run, assuming these probabilities remain constant over time.

if arc QR=3x+38 degrees , arc PS=5x-10 degrees ,and
Answers
Answer:
Arc QR = 111.5°
Step-by-step explanation:
Given:
Arc QR = (3x + 38)°
Arc PS = (5x - 10)°
m<QMP = 68°
Required:
Measure of arc QR
Solution:
Recall: Angles of intersecting chords theorem states that the angle formed equals half of the sum of the intercepted arcs
This by implication means:
m<1 = ½(arc QR + arc PS)
We are given arc QR, and arc PS.
m<1 = 180° - m<QMP (angles on a straight line)
m<1 = 180° - 68°
m<1 = 112°
Plug in the values into the equation and solve for x
112° = ½(3x + 38 + 5x - 10)
Multiply both sides by 2
2*112 = 3x + 38 + 5x - 10
224 = 3x + 38 + 5x - 10
Add like terms
224 = 8x + 28
224 - 28 = 8x + 28 - 28
196 = 8x
196/8 = 8x/8
24.5 = x
x = 24.5
✅Let's find arc QR
Arc QR = (3x + 38)°
Plug in the value of x
Arc QR = 3(24.5) + 38 = 73.5 + 38
Arc QR = 111.5°

The freshman and sophomore classes at Danville High School are decorating floats for homecoming. The freshmen have already spent $44 on their float, plus they need to buy floral sheeting that costs $101 per roll. The sophomores, who have spent $55 so far on theirs, still need to purchase vinyl grass at $100 per roll. Both classes plan to buy the same number of rolls, since they have the same area to cover. By coincidence, the two floats will have the same total cost in the end. How much will each class spend in total? How many rolls will each tlass be buying? The two classes will have each spend $ in total by buying rolls.
Answers
Let x be the number of rolls purchased and y the total cost.
The equation that describes the total cost for freshmen is:
\(44+101x=y\)The equation that describes the total cost for sophomores is:
\(55+100x=y\)Make both equations for y equal and solve for x:
\(\begin{gathered} 44+101x=55+100x \\ 101x-100x=55-44 \\ x=11 \end{gathered}\)Use the value of x to find y:
\(\begin{gathered} 55+100(11)=y \\ 55+1100=y \\ 1155=y \end{gathered}\)It means that the two classes will have each spend $1155 in total by buying 11 rolls.
