The endpoints of PQ are P(-3, 1) and Q(4, 25) Find the midpoint of PQ
Answer:
(-1, 14.5)
Step-by-step explanation:
Well there is a mid-point formula that looks like this:
m = ((x1+x2)/2) , ((y1+y2)/2)
So if we input our two points into the formula we get this:
m=((-3+1)/2) , ((4+25)/2)
Which can be simplified to get:
m=(-1, 14.5)
So these are your coordinates

What is 9x-7=-7 ?????
Answer:
when we stop 9x then
7 will go another side so,.9x=7
and when X is stoppedbit will be=7/9
Answer:
[tex] \sf \: x = 0[/tex]
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
The equation is,
→ 9x - 7 = -7
Then the value of x will be,
→ 9x - 7 = -7
→ 9x = -7 + 7
→ 9x = 0
→ x = 0 ÷ 9
→ [ x = 0 ]
Hence, the value of x is 0.

2,3,5,7,11,13 conjecture
Answer:
The primes up to 50 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43 and 47. The sequence of gaps—the differences between each prime and the next—is 1, 2, 2, 4, 2, 4, 2, 4, 6, 2, 6, 4, 2 and 4. The number 1 appears only once because all primes except for 2 are odd. The rest of the gaps are even numbers.
The conjecture which could be inferred from the sequence is that it is a list of prime numbers.
From the sequence given : 2, 3, 5, 7, 11, 13
All values in the sequence are prime numbers.
Prime numbers are numbers which have only two divisors which are 1 and the number itself.
Divisors of :
2 = 1 and 2
3 = 1 and 3
5 = 1 and 5
7 = 1 and 7
11 = 1 and 11
13 = 1 and 13
Hence, the conjecture which could be inferred from the sequence is that, the numbers are prime numbers.

Answer:
38.11 and 3.66
Step-by-step explanation:
The sample mean and standard deviation for the given data are 38.11 and 3.66 respectively.
What is the mean absolute deviation?The average distance between an observation's mean and its variance is shown by the mean absolute deviation, a measure of variability. mean makes understanding simpler by using the data's original units. A wider deviation from the average is reflected by larger values. The mean absolute deviation is sometimes referred to as the average absolute deviation and the mean deviation.
The mean is the average of the data set and given by
Mean = sum of all the data sets/number of data set
Mean = (33 + 34 + 42 + 36 + 39 + 36 + 39 + 40 + 44)/9
Mean = 38.11
Now standard deviation is given by
[tex]s = \sqrt{\frac{1}{N-1} \sum_{i=1}^N (x_i - \overline{x})^2}[/tex]
Where N is the number of data while the x bar is the mean.
So by using the formula,
Standard deviation = 3.66.
Hence "The sample mean and standard deviation for the given data are 38.11 and 3.66 respectively".

Ivan and Polina have each drawn a conclusion about multiplying negative fractions. Ivan: The product of an even number of negative fractions is always positive. Polina: The product of an odd number of negative fractions is always negative. Whose conclusion is correct? Ivan only Polina only both Ivan and Polina neither Ivan or Polina
Answer:
Both are correct
Step-by-step explanation:
To check the validity of their statements, we shall be using direct examples
For Ivan , we can have an example of his assertion as follows;
-1/2 * -1/3 = 1/6
For Polina, we can have
-1/2 * -1/3 * -1/4 = -1/24
We can see from the above that both of them got their opinions correctly as there are no exceptions to the above
