Answer:
The answer would be 28.
Step-by-step explanation:
Cuz, 10-2=8
8+20=28
So the answer is 28, Hope this helps:)
Answer:
28
Step-by-step explanation:
the sum means it is addition and difference means subtraction.
this means that if you add the difference of 10 and 2 to 20 you will get the answer.
10-2 equals to 8
then do 20+8 to get 28

Which of the following would be the variance of this population data set: 3, 9, 8, 9, 4, 5, 7, 11, 9, 7, 5, 4, 3, 1
Answer:
3
Step-by-step explanation:
The variance of this population data set is 3.
How to find the variance of the set of data?To find the variance of the set of data we first need to calculate the mean of the set.
mean = sum of each element / number of elements
mean = (3 + 9+ 8+ 9+ 4+ 5+ 7+ 11+ 9+ 7+ 5+ 4+ 3+ 1)/14 = 6.07
We can now find the variance by the following formula:
[tex]s^2 = \dfrac{(x- mean)^2}{n- 1}[/tex]
So by applying the data from the problem we have:
s² = [(3 - 6.07)² + (9 - 6.07)² + (8 - 6.07)² + (9 - 6.07)² + ....]/(14 - 1)
s² = [0.36 + 5.76 + 12.96 + 11.56 + 2.56]/13 = 3
Therefore the variance on the data set is 3.

Juan, Marisela y Víctor van al cine y cada uno le tocó pagar 1/3
del total de un combo de palomitas y refrescos a 240 pesos,
¿cuánto le correspondió pagar a cada uno?
Answer:
Cada uno de los asistentes pagó $ 80 pesos por el combo de palomitas y refrescos.
Step-by-step explanation:
El problema nos indica que Juan, Marisela y Víctor pagaron en partes iguales el combo de palomitas y refrescos. Por tanto, la parte correspondiente a cada uno es igual al total pagado dividido entre el número de asistentes. Es decir:
[tex]x = \frac{\$\,240}{3}[/tex]
[tex]x = \$ \,80[/tex]
Cada uno de los asistentes pagó $ 80 pesos por el combo de palomitas y refrescos.
A square has an area of 64 m². What is the length of each side?
Answer:
8m
Step-by-step explanation:
The area of a square is length*width.
We can square root the area to get the length of each side. Since the shape is a square, the lengths are the same.
[tex]\sqrt{64}[/tex]=8
One side is 8m.

Step-by-step explanation:
Two angles of a triangle are the same
size. The third angle is 12 degrees
smaller than the first angle. Find the
meone the ongles
Let the measure of the first angle be = x
Let the measure of the second angle = x
Then , the measure of the third angle = x - 12
Let us find the value of all of these angles using the angle sum property .
Sum of all angles inside a triangle = 180°
[tex]x + x + x - 12 = 180[/tex]
[tex]3x - 12 = 180[/tex]
[tex]3x = 180 + 12[/tex]
[tex]3x = 192[/tex]
[tex]x = \frac{192}{3} [/tex]
[tex]x = 64[/tex]
Which means :-[tex]measure \: of \: the \: first \: angle = x = 64°[/tex]
[tex]measure \: of \: second \: angle \: = 64°[/tex]
[tex]measure \: of \: the \: third \: angle \: = x - 12 = 64 - 12= 52°[/tex]
∴ The measure of the first angle = 64° , the measure of the second angle = 64° and the measure of the third angle = 52° .

On a six-day vacation, the forecast is a 70% chance of rain every day. What’s the probability that it rains every day?
Answer:
0.12 (12%)
Step-by-step explanation:
Step 1: Given data
Probability of rain every day: 70% (0.7)
Step 2: Calculate the probability that it rains every day
The probability that it rains one day is independent of the probability that it rains another day. For independent events, we can calculate the probability that it rains every day by multiplying the individual probabilities. Since the individual probabilities are equal, this is the same as raising the individual probability to the number of days.
P = 0.7⁶ = 0.12

find the nth term in the sequence 7/8, 3/4, 9/14
Given parameters:
Terms of the sequence = 7/8 , 3/4 , 9/14
From terms, we know that our first term is [tex]\frac{7}{8}[/tex]
We need find either of the common difference or the common ratio of this sequence.
For this, the common ratio is applicable.
Common ratio = [tex]\frac{3}{4} / \frac{7}{8}[/tex]
This is the factor by which when we multiply the subsequent terms with results into them;
Solving the above gives [tex]\frac{6}{7}[/tex]
The common ratio is 6/7.
To find the nth of this sequence we apply the formula below;
A[tex]_{n}[/tex] = Arⁿ⁻¹
Aₙ is the term we are looking for
A is the first term of the sequence
r is the common ratio
n is the position of the term
So for any nth term in this sequence;
Aₙ = [tex]\frac{7}{8}[/tex] x [tex]\frac{6}{7}[/tex] ⁿ⁻¹
We can use the above solution to find any term in the sequence.
Find the slope of the line satisfying the given condition. Through (3,-6) and (-9,-1)
Answer:
C) -5/12
Step-by-step explanation:
To find the slope of a line with given points, you divide the difference of y-coordinates by the difference of the x-coordinates of those same 2 points.
x's:-9-3=-12
y's:-1-(-6)=5
Then, you put the answer of the y's in the numerator, and x's in the denominator, giving you 5/-12, but you can't have a negative in the denominator, moving it up to become -5/12 as the slope.
