A swim instructor would like to test the effect of a new swim technique versus the standard technique for a group of 25 competitive swimmers.
The swim instructor divides the students by class (junior or senior), and then randomly allocates half of the 14 juniors and 5 of the 11 seniors to receive instruction on the new technique.
During swim practice, the instructor times the juniors as they race against each other to see if those who learned the new technique outperform their peers. The instructor does the same for the seniors.
At the end of practice, the instructor compares the average swim time for both juniors and seniors among those who did and did not use the new technique.
A) The instructor should place the 25 student names on slips of paper and place them in a hat. Twelve of the slips should be drawn out and those students should receive the instruction on the new technique.
B) The instructor should place the names of the 14 juniors on slips of paper and place them in one hat. The 11 seniors’ names should be placed on slips of paper and placed into a separate hat. The instructor should randomly select 7 juniors and 5 seniors to receive instruction on the new technique.
C) For each student, the instructor should flip a coin. If the coin lands on heads, the student will receive instruction on the new technique. If the coin lands on tails, the student will not receive instruction on the new technique.
D) The students should line up alphabetically and count off by 2s. Every student who gets a 1 will receive instruction on the new technique. Every student who gets a 2 will not receive instruction on the new technique.

Steven needed to mail a holiday envelope to his Aunt Linda. He used $0.02 stamps and $0.10 stamps to mail the gift. If he used 15 stamps worth $0.78, how many of each type of stamp did he use?
Answer:Steven used 9 $0.02 stamps and 6 $0.10 stamps
Step-by-step explanation:
let number of $0.02 stamp be =x
let number of $0.10 stamp be =y
so that the number of stamps used can be expressed as
x+y=15
and the total price of stamps used equaling $0.78 be expressed as
0.02x + 0.10y =0.78
Solving
x+y=15----1
0.02x + 0.10y =0.78---2
from equation 1 , x =15-y, putting the value of x into equation 2
0.02(15-y) + 0.10y =0.78
0.3 -0.02y + 0.10y = 0.78
0.3 + 0.08y=0.78
0.08y=0.78-0.3
y=0.48/0.08 =6
y =6 stamps
Putting bthe value of y =6 into equation 1
x+6=15
x=15-6 =9
Steven used 9 $0.02 stamps and 6 $0.10 stamps

O (x, y) — (X-8, y + 4)
O(x, y) - (x + 8, y–4)

The translation rule will be (x+8 , y+4).
What is Transformation?A transformation is a broad phrase covering four distinct methods of changing the shape and/or position of a point, line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
When we scale a triangle by some factor, neither its shape nor size change. The image corresponds to the previous image.
The horizontal translation of x coordinate is either horizontally right or horizontally left depending on the positive or negative value of x - coordinate.
Depending on the positive or negative value of the y - coordinate, the y coordinate is translated vertically up or down.
Here (8 ,4) shows there is shifting Horizontally right (x+ 8) and there is shifting Vertically up (y + 4).

how do I do probabillty
Answer:
Divide the number of events by the number of possible outcomes. This will give us the probability of a single event occurring. In the case of rolling a 3 on a die, the number of events is 1 (there's only a single 3 on each die), and the number of outcomes is 6.
Answer:
what the other guy said
Step-by-step explanation:
Select the correct answer. Two events, E1 and E2, are defined for a random experiment. Which equation represents the condition that the events are nonexclusive? A. P(E1 ∩ E2) ≠ 0 B. P(E1 ∪ E2) ≠ 1 C. P(E1 ∩ E2) = 0 D. P(E1 ∪ E2) = 1
Answer:
B
Step-by-step explanation:
The equation that represents the condition that the events are nonexclusive is P(E1 ∪ E2) ≠ 1.
We have given that,
A. P(E1 ∩ E2) ≠ 0 B. P(E1 ∪ E2) ≠ 1 C. P(E1 ∩ E2) = 0 D. P(E1 ∪ E2) = 1
We have to determine which equation represents the condition that the events are nonexclusive.
What is nonexclusive?
Non-mutually exclusive events are events that can happen at the same time.
The equation that represents the condition that the events are nonexclusive is P(E1 ∪ E2) ≠ 1.

Option (D) 3024 is the permutation value is the correct answer.
What is a permutation?A permutation is an arrangement of objects in a definite order. It is a number of ways a particular set can be arranged, where the order of the arrangement matters.
For the given situation,
The value of 9P4
The formula to find permutation is

Here, n = 9 and r = 4
⇒ [tex]9P_{4}=\frac{9!}{(9-4)!}[/tex]
⇒ [tex]\frac{9!}{5!}[/tex]
⇒ [tex]\frac{5!(6)(7)(8)(9)}{5!}[/tex]
