[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}[/tex]
When solving an equation, we need to make sure that all variables are on one side and all numbers are on the other side.
Since we have numbers on both sides, we need to move all of them to one side:-
[tex]\tt{16+y=24}[/tex]
[tex]\tt{y=24-16}[/tex]
[tex]\tt{y=8}[/tex]

Which equation is true when r = 7 ?
Answers
Answer:
7 = 49 ÷ r
Step-by-step explanation:
To find the equation that is true when r = 7, we need to find a number after the equals sign that is a multiple of 7.
Multiples of 7:
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77...
Therefore, the only answer option in which the number after the equals sign is a multiple of 7 is:
7 = 49 ÷ r
To prove this, input r = 7 into each of the equations:
6 = 30 ÷ r
⇒ 6 = 30 ÷ 7
⇒ 6 ≠ 4.285... ← incorrect!
7 = 54 ÷ r
⇒ 7 = 54 ÷ 7
⇒ 7 ≠ 7.714... ← incorrect!
7 = 49 ÷ r
⇒ 7 = 49 ÷ 7
⇒ 7 = 7 ← correct!
9 = 72 ÷ r
⇒ 9 = 72 ÷ 7
⇒ 9 ≠ 10.285... ← incorrect!

Answer: see photo#2
Step-by-step explanation:
For one binomial experiment, n1 = 75 binomial trials produced r1 = 30 successes. For a second independent binomial experiment, n2 = 100 binomial trials produced r2 = 50
successes. At the 5% level of significance, test the claim that the probabilities of success for the two binomial experiments differ.
(a) Compute the pooled probability of success for the two experiments. (Round your answer to three decimal places.)
(b)Compute the corresponding sample distribution value. (Test the difference p1 − p2. Do not use rounded values. Round your final answer to two decimal places.)
(c)Find the P-value of the sample test statistic. (Round your answer to four decimal places.)

Step-by-step explanation:
A personal trainer determines that an individual will get the most benefit from a workout if they keep their heart rate at an average of 150 beats per minute during workouts. To determine if the individual is doing so successfully, a random sample of 30 workouts is selected from their fitness watch. A 95% confidence interval for these workouts reveals that the true mean heart rate while working out is between 158 and 167 beats per minute. Based upon this interval, what conclusion should be made about the hypotheses: H Subscript 0 Baseline: mu = 150 versus H Subscript alpha Baseline: mu not-equals150 where μ = this individual’s true mean heart rate during working out at α = 0.05?
Reject H0. There is convincing evidence that the mean heart rate from these 30 workouts differs from 150.
Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.
Fail to reject H0. There is not convincing evidence that the mean heart rate from these 30 workouts differs from 150.
Fail to reject H0. There is not convincing evidence that this individual’s true mean heart rate while working out differs from 150.
Answers
Using the confidence interval, it is found that the correct conclusion regarding the hypotheses test is given by:
Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.
What are the hypotheses tested?At the null hypotheses, it is tested if the mean is of 150, that is:
[tex]H_0: \mu = 150[/tex]
At the alternative hypotheses, it is tested if the mean is different of 150, hence:
[tex]H_0: \mu \neq 150[/tex].
The confidence interval is (158, 167). Since it does not contain 150, we reject the null hypotheses, hence the correct option is:
Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.

make x the subject: y=x+p/x-p
step-by-step explanation please
Answers
Answer:
x = p + yp / y - 1
Step-by-step explanation:
y = x+p / x-p
y(x-p) = x + p
y(x-p) -x = p
yx - yp - x = p
yx - x = p + yp
x(y - 1) = p + yp
x = p + yp / y - 1
the teacher had 9 pencils. she gave 6 pencils as prizes to the students what fraction of pencils did she have left.
Answers
Answer:
3/9 (or) 1/3 (reduced)
Step-by-step explanation:
1. Before handing pencils to the students, the teacher had 9 out of 9 (9/9) pencils.
2. When she gave pencils to the students, she gave them 6 of the 9 pencils (6/9)
3. Now we do the math:
9/9 - 6/9
= 3/9 (or) 1/3 (reduced)
Therefore, the teacher now has 3/9 or 1/3 of the pencils left.

Choose the conjecture that describes how to find the 6th term in the sequence 4, 20, 36, 52, ….
A)
Add 16 to 32.
B)
Add 32 to 52.
C)
Multiply 52 by 5.
D)
Multiply 52 by 9.
Answers
Answer:
B
Step-by-step explanation:
there is a common difference between consecutive terms in the sequence, that is
20 - 4 = 36 - 20 = 52 - 36 = 16
thus to obtain the next term in the sequence add 16 to the previous term
To obtain 2 terms distant then add 16 + 16 = 32
so 6th term = 52 + 32 = 84
Mrs. Smith gave two classes the same quiz. She randomly selected 5 students from each class to compare the classes. The scores of the five students are shown below. Class A: 80, 82, 74, 92, 94 Class B: 82, 80, 88, 86, 82
What are the mean and range for each class ?
Class A- mean = 84.4 range = 14
Class B - mean = 83.6. range = 8
Using the information found in the question above which class mrs smith report had the more consistent performance on the unit test ?, explain what this means in terms of the situation
Answers
The mean and range for class A are 84.4 and 20 while the mean and range for class B are 83.6 and 8. Class B is more consistant then class A.
How to calculate the mean?We can see from the data that the consistency of class B is more becuase the repeatation of the same score is more in class B then class A and the range of class B is also less then the class A.
It should be noted that mean simply means average. It's the addition of the numbers divided by the total numbers.
In this case, the computation will be:
Class A: Mean = 422/5= 84.4.
Range: 94-74 = 20
Class B: Mean = 418/5 = 83.6.
Range= 88-80 = 8
