Answer:
(i) 4r + 3p (ii) 3q - 2p when 3q > 2p (iii) 2y + 2/3 x [not sure what [3] means]
Step-by-step explanation:
So for part (i) 3 multiply p added to 4 times r = 3p + 4r
For part (ii) since subtraction can seem like a negative number you stipulate that 3q is greater than 2p so that is will hold true!
(iii) I'm not sure what the [3] means but just using the numbers [tex]\frac{2}{3}[/tex]x, since of means multiply and add 2y then you have 2y + [tex]\frac{2}{3}[/tex] x

how do i rewriting 2 5/10
Answer: 11/2
Step-by-step explanation:
to rewrite as mixed number you multiply the whole number by the denominator and add that to the numerator and get 55/10, then simplify it to 11/2 easy. also for decimal its jus 5.5
The other form to write 2 5/10 is 52/10.
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

Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .

Answer:
3rd answer choice
Step-by-step explanation:
Any time you have a proportion, the two ratios have to match, so 32 and x+8 are the bases, so you need to length of the side of those bases, 20 is the length of the base for the 32, but notice how 5 is not the side for x+8, therefore, 20-5 = 15, so 15 is the side adjacent to the base x+8, and they are in the right order small side / big side = small base / big base
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.
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.

(6x-1)°=(6(10)-1)° don’t know?

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 °

The average of six numbers is 4. If the average of two if those numbers is 2,what is the average of the other 4 numbers?
Answer: Average of other 4 numbers =5
Step-by-step explanation:
Sum of n numbers = Average of n numbers x n
Given: Average of 6 numbers =4
so sum of 6 numbers = 6x 4 = 24
Average of 2 numbers = 2
Sum of 2 numbers = 2 x 2 =4
Sum of rest of 4 numbers = sum of 6 numbers - Sum of 2 numbers
= 24-4
=20
Average of 4 numbers = [tex]\dfrac{20}{4}[/tex]
i.e. Average of 4 numbers =5
If one event impacts the probability of a second event occurring, than which of the following is true?
The events are complements.
The events are dependent.
The events are independent.
Answer:
The events are dependent.
Step-by-step explanation:
Two events A and B are said to be independent if the fact that one event has occurred does not affect the probability that the other event will occur. If whether or not one event occurs does affect the probability that the other event will occur, then the two events are said to be dependent.

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
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 area of the figure below?
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.
