Tomás is gathering data about the sleeping habits of high school students. So far, he has completed 3 different surveys, each with 70 respondents.
What should Tomás expect as he continues his data-gathering process?
As the number of surveys increases, the mean of the sample means will approach ______, and the means will be ___________.
70 Points
Answer:
The population mean
Normally distributed
Please give me brainliest, I really need it.
a)As the number of surveys increases, the mean of the sample means will approach the population mean.
b)Means will be normally distributed.
What is a normal distribution?A normal distribution is a probability distribution that is symmetric about the mean, and data near the mean are more frequent than data far from the mean.
As the number of surveys increases, we will have more data.
So, the mean of the sample means will approach the population mean.
Means will be normally distributed because each survey has the same number of respondents.
Thus, a)as the number of surveys increases, the mean of the sample means will approach the population mean.
b)Means will be normally distributed.

A number decreased by the sum of the number and seven. what is the algebraic expression?
Answer:
Step-by-step explanation:
n-(7+n) which is a strange problem to give you as that is equal to
n-7-n which always equals -7
And that means n can be any real number and the expression still equals -7
The algebraic expression will be -7. x is the assumed algebraic expression. The equation is solved by subtraction.
What is an algebraic expression?An algebraic expression is a phrase that has been combined using operations like addition.
Let n is the number and x be the solution for the given condition;
If the number is decreased by 7 then the equitation will be (n-7).
From the given condition;

On a BWIA flight, 2/3 of the
passengers are from Trinidad.
If there are 189 passengers
altogether, how many were
from Trinidad?
Answer:
126 passengers from Trinidad.
Step-by-step explanation:
Given that,
On a BWIA flight, 2/3 of the passengers are from Trinidad.
Total passengers = 189
We need to find how many were from Trinidad. It can be calculated by finding 2/3 of 189 such that,
[tex]P=\dfrac{2}{3}\times 189\\\\=126[/tex]
Hence, there were 126 passengers from Trinidad.

Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(3, −6), Q(0, 9), and R(−3, 0). Triangle P′Q′R′ has vertices P′(1, −2), Q′(0, 3), and R′(−1, 0).
Plot triangles PQR and P′Q′R′ on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)
Part C: Are the two triangles PQR and P′'Q′'R′' congruent? Explain your answer. (2 points)
Answer:
P' = 1/3 P
reflection in the y-axis just changes the sign of all the x-values.
Since P" ≅ P', and P' is smaller than P, P" cannot be ≅ to P

.On 1st March 2001, the ratio of Freddie’s age to his mother’s age was 1:11
On 1st March 2018, the ratio of Freddie’s age to his mother’s age was 2:5
Write the ratio of Freddie’s age to his mother’s age on 1st March 2030
Answer:
[tex]Ratio =16 : 31[/tex]
Step-by-step explanation:
Let
x = Freddie's age and y = His mother's age
Given
2001:= [tex]x : y = 1 : 11[/tex]
2018:= [tex]x +17: y + 17= 2 : 5[/tex]
Required
The ratio of their age in 2030
[tex]x : y = 1 : 11[/tex]
[tex]x +17: y + 17= 2 : 5[/tex]
Express as fractions
[tex]\frac{x}{y} = \frac{1}{11}[/tex] --- (1)
[tex]\frac{x+17}{y+17} = \frac{2}{5}[/tex] -- (2)
In (1), make y the subject
[tex]\frac{x}{y} = \frac{1}{11}[/tex]
[tex]y = 11x[/tex]
Substitute [tex]y = 11x[/tex] in (2)
[tex]\frac{x+17}{y+17} = \frac{2}{5}[/tex]
[tex]\frac{x+17}{11x+17} = \frac{2}{5}[/tex]
Cross Multiply
[tex]5(x +17) = 2(11x + 17)[/tex]
[tex]5x +85 = 22x + 34[/tex]
Collect like terms
[tex]22x - 5x = 85 - 34[/tex]
[tex]17x = 51[/tex]
[tex]x =3[/tex]
[tex]y = 11x[/tex]
[tex]y = 11*3[/tex]
[tex]y = 33[/tex]
This means that: In 2001, Freddie was 3 and his mother was 33
In 2030 (29 years after);
Freddie will be: 3 + 29 = 32
His mother will be: 33 + 29 = 62
So, the ratio is:
[tex]Ratio =32 : 62[/tex]
Divide by 2
[tex]Ratio =16 : 31[/tex]

is (x-4) a factor of 2x^4-9x^3-20x^2+147x-180? find out by using the factor theorem.
Answer: (x-4) is not a factor of the given polynomial.
===================================================
Explanation:
Rule: If (x-k) is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem. We can take this in reverse to say that if p(k) = 0, then (x-k) must be a factor of p(x).
In this case, we have k = 4 and we can find that:
p(x) = 2x^4-9x^3-20x^2+147x-180
p(4) = 2(4)^4-9(4)^3-20(4)^2+147(4)-180
p(4) = 24
The result we get is not zero, so that means (x-4) is not a factor of p(x).
