Tom and Katie are discussing the sequence: 22, 17, 12, 7, 2
Tom says the nth term rule is: -5n+17
Katie says the nth term rule is: 27-5n

A)Only Tom is correct
B)Only Katie is correct
C)They both are correct
D)Neither are correct

Answers

Answer:

B

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 17 - 22 = 12 - 17 = 7 - 12 = 2 - 7 = - 5

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 22 and d = - 5, then

[tex]a_{n}[/tex] = 22 - 5(n - 1) = 22 - 5n + 5 = 27 - 5n → B

What is the percentage?

A relative value indicating hundredth parts of any quantity is called the percentage.

Now,

A shop owner increases some prices by 50%.

Let the original price is x.

Then, The increase value = x * 50% = x * 50/100 = 0.5x

Hence, To find the increase value we have to multiply by 0.5 with original price.

What is fraction?

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.

We have mixed fraction as 2 5/10.

Now, to write the mixed fraction into normal we must follow:

Numerator = Divisor x Quotient+ Remainder

Here, Divisor= 10, Quotient = 2 and Remainder= 5

So, the Normal Fraction is

= ( 10 x 5 +2)/ 10

= 52/10

What is the area of the figure below?

Answers

Answer:

104

Explanation:

1. Split the figure by the line the larger portion creates.

2. Calculate the area of the left-hand side... 7 · 8 = 56cm squared.

3. You know that the total length of the figure is 15cm. You've already "used" 7cm of that. So... 15 - 7 = 8.

4. Now, we simply do 6 · 8 = 48. Almost there!

5. Finally, add the values of the left side and the right side (48 + 56 = 104)

6. YOUR ANSWER IS 104 cm squared.

A therapist wanted to determine if yoga or meditation is better for relieving stress. The therapist recruited 100 of her high-stress patients. Fifty of them were randomly assigned to take weekly yoga classes, and the other 50 were assigned weekly meditation classes. After one month, 30 of the 50 patients in the yoga group reported less stress, and 35 of the 50 patients in the meditation group reported less stress.

Based on the 95% confidence interval, (–0.29, 0.09), is there convincing evidence of a difference in the true proportions of patients experiencing stress relief in the yoga and meditation groups?

There is convincing evidence because the two sample proportions are different.

There is not convincing evidence because the interval contains 0.

There is not convincing evidence because the interval contains both negative and positive values for the true difference.

Answers

Answer:  Choice B

There is not convincing evidence because the interval contains 0.

========================================================

Explanation:

The confidence interval is (-0.29, 0.09)

This is the same as writing -0.29 < p1-p1 < 0.09

The thing we're trying to estimate (p1-p2) is between -0.29 and 0.09

Because 0 is in this interval, it is possible that p1-p1 = 0 which leads to p1 = p2.

Therefore, it is possible that the population proportions are the same.

The question asks " is there convincing evidence of a difference in the true proportions", so the answer to this is "no, there isn't convincing evidence". We would need both endpoints of the confidence interval to either be positive together, or be negative together, for us to have convincing evidence that the population proportions are different.

There is not convincing evidence because the interval contains 0.

What is Confidence Interval?

The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.

We have, the confidence interval as (-0.29, 0.09)

and, the same as writing -0.29 < p1-p1 < 0.09

Now, as the interval is 0 then

p1 - p2 = 0

p1 = p2

There is a chance that the population ratios are identical.

So, there isn't convincing evidence.

For us to have strong evidence that the population proportions are different, the ends of the confidence interval must be either positive together or negative together.

I don’t know how to do this help me

Answers

Answer:

The answer: ( 2 , -3 )

Step-by-step explanation:

equation (1): 5x + 2y = 4

equation (2): y = x - 5

step1: sub ( x-5 ) for y in equation 1:

5x + 2 ( x-5 ) = 4

step2: multiply 2 by the bracket:

5x + 2x - 10 =4

step3: add the x term together:

7x - 10 = 4

step4: add 10 for both sides:

7x = 14

step5: divide by 7 from both sides to get the value of x:

x = 2

step6: sub ( 2 ) for x in equation 2 :

y = x - 5

y = 2 - 5

step7: simplify to get the value of y:

y = -3

So the answer is:

x = 2   and   y = -3

Answer:

  x = 10

Step-by-step explanation:

You can compare parts of each expression to see that x in the left-side expression is replaced by 10 in the right-side expression.

  x = 10

__

If you'd rather, you can work your way down to the same conclusion by undoing the operations that have been done to x.

  (6x -1)° = (6(10) -1)° . . . . . . given

  6x -1 = 6(10) -1 . . . . . . . . . divide both sides by °

  6x = 6(10) . . . . . . . . . . . .  add 1 to both sides

  x = 10 . . . . . . . . . . . . . . . . divide both sides by 6
