The number of cars sold at a dealership over several weeks is given below. 14, 23, 31, 29, 33 what is the standard deviation for this set of population data? standard deviation: sigma = startroot startfraction (x 1 minus mu) squared (x 2 minus mu) squared ellipsis (x n minus mu) squared over n endfraction endroot 6.9 12.4 15.4 47.2
The standard deviation for this set of population data is 6.9. Then the correct option is A.
What is a standard deviation?It is the measure of the dispersion of statistical data. Dispersion is the extent to which the value is in a variation.
The number of cars sold at a dealership over several weeks is given below.
14, 23, 31, 29, 33.
Then the mean will be
[tex]\mu = \dfrac{14+23+31+29+33}{5}\\\\\\\mu = \dfrac{130}{5}\\\\\\\mu = 26[/tex]
Then the standard deviation is given as
[tex]\sigma = \sqrt {\dfrac{\Sigma _{i=1}^n(x_i - \mu)^2}{n}}\\\\\\\sigma = \sqrt{\dfrac{(14-26)^2+ (23-26)^2+ (31-26)^2+ (29-26)^2+ (33-26)^2}{5}}\\\\\\\sigma = \sqrt{\dfrac{236}{5}}\\\\\\\sigma = \sqrt{47.2}\\\\\\\sigma = 6.87 \approx 6.9[/tex]
The standard deviation for this set of population data is 6.9. Then the correct option is A.

An engineer was supposed to draw a line exactly 7/10 centimeters long. An error was made, and he drew the line 9/10 centimeters long. How much longer than needed was the line the engineer drew?
Answer:
2/10 or 1/5 if you want it simplified
Step-by-step explanation:
9/10 is basically 9 and 7/10 is 7 so 9 - 7 is 2 and we need to add the /10 back so it's 2/10 or 1/5
Step-by-step explanation:
want to draw=7/10

One angle of an isosceles triangle measures 124 degrees. What measures are possible for the other
two angles? Choose all that apply.
44
81°
11°
28°
Answer:
28°
Step-by-step explanation:
In an isosceles triangle, by definition two of the three sides of the triangle are equal to one another. Therefore, the angles opposite to these sides must also be equal. And considering the Triangle Sum Theorem, the angles of a triangle must add up to 180 degrees, the angle that measures 124 degrees cannot be be equal to another angle due to the fact that the sum of them would exceed 180. Therefore let x be the angle:
124+2x=180
2x=56x=28°

If x is temperature and y is coffee sales, use the following formula to determine the
coffee sales on a 34 day
Y=60x+6443
A.$6443
B.$4673
C.$8483
D.$4403
Answer:
C. $8483
Step-by-step explanation:
To find the coffee sales, we plug in the value of x as 34 into y = 60x + 6443.
[tex]y=60(34)+6443[/tex] [tex]y=2040+6443[/tex] [tex]y=8483[/tex]Therefore, the answer is C. $8483.00.
The students in Mary’s class sold cookies for a fundraiser this year and last year. This year, the selling price of a box of cookies was $13.25. The price this year represents 6% more than the selling price of each box last year.
Find 6% of 13.25
0.06 x 13.25 = 0.795
Then subtract 0.795 from 13.25 because the price was less last year
13.25-0.795 = 12.455
Rounded up that would be $12.46 last year

Consider all six-digit numbers that can be created from the digits 0-9 where the first and last digits must be odd and no digit can repeat. What is the probability of choosing a random number that starts with 9 from this group? Enter a fraction or round your answer to 4 decimal places, if necessary
Using the Fundamental Counting Theorem, it is found that there is a 0.2 = 20% probability of choosing a random number that starts with 9 from this group.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem, we have that:
The first and last digit have to be odd, hence [tex]n_1 = 5, n_6 = 4[/tex].The others cannot repeat, hence: [tex]n_2 = 8, n_3 = 7, n_4 = 6, n_5 = 5[/tex].Then, the total number is:
N = 5 x 4 x 8 x 7 x 6 x 5 = 33600.
Starting with 9, we have that:
The first digit is 9, the last digit has to be an odd which is not 9, hence [tex]n_1 = 1, n_6 = 4[/tex].The others cannot repeat, hence: [tex]n_2 = 8, n_3 = 7, n_4 = 6, n_5 = 5[/tex].Then:
N9 = 1 x 4 x 8 x 7 x 6 x 5 = 6720.
A probability is given by the number of desired outcomes divided by the number of total outcomes, hence:
p = N9/N = 6720/33600 = 0.2.
0.2 = 20% probability of choosing a random number that starts with 9 from this group.

Step-by-step explanation:
the answer is 5
Answer:
JH=16
Step-by-step explanation:
Hi there!
We are given ΔHIJ, where HI is parallel to KL, and that JK=10, JI=40, and JL=25
We want to find JH
We can use something called the Triangle Proportionality Theorem to help us find JH
The Triangle Proportionality Theorem essentially states that if there is a line parallel to one of the sides of a triangle that intersects the other 2 sides of that triangle, then that segment divides those sides proportionally
In other words, KL is parallel to HI and intersects both HJ and JI, and JK, JH, JL, and JI create a proportion, which is [tex]\frac{JK}{JH} =\frac{JL}{JI}[/tex]
We can substitute the values that we know into that equation
[tex]\frac{10}{JH} =\frac{25}{40}[/tex]
We can simplify 25/40 to 5/8.
[tex]\frac{10}{JH} =\frac{5}{8}[/tex]
Now we can cross multiply (use the means-extreme theorem)
Multiply 10 and 8 together, and set that equal to 5 times JH
80 = 5JH
Divide both sides by 5
16=JH
Hope this helps!

What is an inequality?An inequality is an expression that shows the relationship between two or more numbers and variables.
Given the inequality x ≤ 10. To graph this inequality, we need to represent it on a number line.
When representing on a number line, closed circle is used to represent ≤ or ≥ while open circle represents < or >.

Question :-
Find the Area of Parallelogram whose Height is 5 cm and the Base is 8 cm .Answer :-
Area of Parallelogram is 40 cm² .Explanation :-
As per the provided information in the given question, we have been given that the Height of the Parallelogram is 5 cm . Its Base is given as 8 cm . And, we have been asked to calculate the Area of Parallelogram .
For calculating the Area , we will use the Formula :-
[tex] \bigstar \: \: \: \boxed{ \sf{ \: Area \: _{Parallelogram} \: = \: Base \: \times \: Height \: }} [/tex]
Therefore , by Substituting the given values in the above Formula :-
[tex] \dag \: \: \: \sf {Area \: _{Parallelogram} \: = \: Base \: \times \: Height} [/tex]
[tex] \longmapsto \: \: \sf {Area \: _{Parallelogram} \: = \: 8 \: \times \: 5} [/tex]
[tex] \longmapsto \: \: \bf {Area \: _{Parallelogram} \: = \: 40} [/tex]
Hence :-
Area of Parallelogram = 40 cm² .[tex] \underline {\rule {180pt} {4pt}} [/tex]
Identify the solution to the following inequality: -1/2 (x+3) > x - 3
A. X < 1
B. X > 3
C. X > 1
D. X< 3
Answer:
A
Step-by-step explanation:
- [tex]\frac{1}{2}[/tex] (x + 3) > x - 3 ( multiply both sides by 2 to clear the fraction )
- (x + 3) > 2x - 6 ← distribute parenthesis on left side by - 1
- x - 3 > 2x - 6 ( subtract 2x from both sides )
- 3x - 3 > - 6 ( add 3 to both sides )
- 3x > - 3
divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity
x < 1
Answer:
A. x<1
Step-by-step explanation:
-1/2 (x+3) > x - 3
(-1/2)x-3/2>x-3
Multiply both sides by 2:
-x-3>2x-6
add both sides by 3:
-x-3+3>2x-6+3
-x>2x-3
minus both sides by 2x
-x-2x>2x-2x-3
-3x>-3
x<1
