The total number of points scored during 10 football games are shown below 45,47,23,30,27,31,21,31,22,38 select the correct five-number summary from the data set
Answer:
[tex]Min=21, Q_1=23, M=30.5, Q_3=38,Max=47[/tex].
Step-by-step explanation:
The given data set is
45, 47, 23, 30, 27, 31, 21, 31, 22, 38
Arrange the data is ascending order.
21, 22, 23, 27, 30, 31, 31, 38, 45, 47
Divide the data in 4 equal parts.
(21, 22),23, (27, 30),( 31, 31), 38, (45, 47)
Now,
Minimum value = 21
First quartile, [tex]Q_1=23[/tex]
Median, [tex]M=\dfrac{30+31}{2}=30.5[/tex]
Third quartile, [tex]Q_3=38[/tex]
Maximum value = 47
Therefore, the five-number summary for the given data set is [tex]Min=21, Q_1=23, M=30.5, Q_3=38,Max=47[/tex].

Solve for r. 7(r+1) = 20.3
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{r = 1.9}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{7(r + 1) = 20.3}[/tex]
Distribute 7 through the parentheses
⇒[tex] \sf{7r + 7 = 20.3}[/tex]
Move 7 to right hand side and change it's sign
⇒[tex] \sf{7r = 20.3 - 7}[/tex]
Subtract 7 from 20.3
⇒[tex] \sf{7r = 13.3}[/tex]
Divide both sides of the equation by 7
⇒[tex] \sf{ \frac{7r}{7} = \frac{13.3}{7} }[/tex]
Calculate
⇒[tex] \sf{r = 1.9}[/tex]
Hope I helped!
Best regards!!
r is 1.9
Solve 7(r+1) = 20.3
Remove the brackets by dividing both sides by 7:
7(r+1) / 7 = 20.3 / 7
r + 1 = 2.9
Take 1 to the other side so that you can be left with r. When you do this, the sign will change from positive to negative:
r = 2.9 - 1
r = 1.9
r is therefore 1.9

an = an - 1 + 3n
an = an - 1 +n + 2)
an = an - 1 + 3(n + 2)
an = an - 1 + (3n + 2)
Answer:
a[n] = a[n-1] +(3n +2)
Step-by-step explanation:
The difference between Day 1 and Day 2 is 9 - 1 = 8 cells. The difference between a2 and a1 in each of the answer choices is a2 -a1 = ...

a polynomial has one quadratic factor and 3 linear factors. One of the linear factors has multiplicity two. What is the degree of the polynomial
Answer:
5
Step-by-step explanation:
a polynomial has one quadratic factor and 3 linear factors. One of the linear factors has multiplicity two. What is the degree of the polynomial
A polynomial with one quadratic obtains the forms ( ax² +bx +c ) with 3 linear factors.
Suppose the three linear fractions are :
(x- P) (x-Q) (x- R)
∴
The polynomial = ( ax² +bx +c )(x- P) (x-Q) (x- R)
By factorization, the highest degree of the polynomial = 5

Which angle pairs are supplementary? Check all that
apply.
<1 and <2
<4 and <3
<4 and <5
<7 and <5
<3 and <6
Answer:
∠4 and ∠3
∠4 and ∠5
∠3 and ∠6
Step-by-step explanation:
A pair of angles is said to be supplementary when the 2 angles add up to give 180°.
Two right angles add up to give 180°. Also, if we have two angles on a straight line, their sum = 180°, according to the linear pair property.
Thus, since m< 3 is given as 90°, m<4 = 90°.
m<4 + m<3 = 180°.
Therefore, <4 and <3 are supplementary.
<4 and <5, <3 and <6 are both linear pairs, therefore they are also supplementary.

a saleswoman earns 60% commission on all that she sells. Last month she sold $400 worth of merchandise. How much commission (In dollars) did she earn last month?
Answer:
$240
Step-by-step explanation:
If she earns 60% commission, that means she only earns 60% of all sales. So if you take that 60% or (.60) you can multiply that 400 by .60, that equates to 240.
Three students need to produce a prime factorization of 48. Donna states that the first factors in the tree should be 6 and 8. Larry states that the first factors in the tree should be 4 and 12. Trish states that the initial factors of 48 do not affect the prime factorization. Explain why Trish is correct. Why is trish correct?
Answer:
Below.
Step-by-step explanation:
The initial factors do not affect the prime factorisation.
Continuing the factorisation will lead to the same result whichever initial factors you choose.
48
4 * 12
2*2 * 2*2*3
= 2*2*2*2*3
48
6 * 8
2*3 * 2*2*2
= 2*2*2*2*3.
Answer:
A prime factorization is the product of the prime numbers that multiply to give the original number. 48 will have a prime factorization of 2(2)(2)(2)(3), or 24(3), regardless of the initial factors.

The sum of two numbers is fifteen. One number is three less than the other. Determine the system of equations.
Answer:
let, one number be x
then, other number be x-3
X+X-3=15
or, 2X=15+3
or,2X=18
or,X=18÷2
or,X=9
one number =9
then another number=X-3=9-3=6
The system of equations with two numbers x ad y are,
⇒ [tex]x + y = 15[/tex]
⇒ [tex]x = y - 3[/tex]
Given that,
The sum of two numbers is fifteen.
And, One number is three less than the other.
Let us assume that,
Two variables for the numbers in the system of equations are x and y.
Hence, we can write the system of equations as,
The sum of two numbers is fifteen.
⇒ [tex]x + y = 15[/tex]
And, One number is three less than the other.
⇒ [tex]x = y - 3[/tex]
So, the system of equations is,
⇒ [tex]x + y = 15[/tex]
⇒ [tex]x = y - 3[/tex]

what is the percentage of the total variation in candy bar sales explained by the regression model? a. 78.39% b. 88.54% c. 100% d. 48.19%
Complete question :
A candy bar manufacturer is interested in trying to estimate how sales are influenced by the price of their product. To do this, the company randomly chooses 6 small cities and offers the candy bar at different prices. Using candy bar sales as the dependent variable, the company will conduct a simple linear regression on the data below:
City - - - - - Price ($) -- - Sales
River City - - 1.30 - - - - - - 100
Hudson - - - 1.60 - - - - - 90
Ellsworth - - - 1.80 - - - - - 90
Prescott - - - - 2.00 - - - - 40
Rock Elm - - 2.40 - - 38
Stillwater - - 2.90 - - 32
Answer:
78.39%
Step-by-step explanation:
what is the percentage of the total variation in candy bar sales explained by the regression model?
The question could be interpreted as meaning the percentage of the total variation in the dependent variable (candy bar sales) which can be explained by the regression model. Hence the independent variable is price. This variance can be known by calculating the Coefficient of determination (R^2) value of the regression model.
To save computation time, the R^2 value can be obtained using an online Coefficient of determination calculator.
To obtain the R^2 value, the values of the dependent and independent variables are entered. The R^2 value obtained is : 0.7839
Therefore the total proportion of variance in candy bar sales explained by the regression model is 0.7839 which is equivalent to:
(0.7839 * 100) = 78.39%

Please Help ASAP it's my Math HW
Step-by-step explanation:
Use segment addition/subtraction:
GK = GJ − HJ + HK
GK = 2x + 5 − x + 4x − 1
GK = 5x + 4
If GK = 39, then the value of x is:
39 = 5x + 4
5x = 35
x = 7
Use segment subtraction to find GH and JK.
GH = GJ − HJ
GH = 2x + 5 − x
GH = x + 5
GH = 12
JK = HK − HJ
JK = 4x − 1 − x
JK = 3x − 1
JK = 20

Answer:
-4-5
Step-by-step explanation:
The temp was at -4 and if it dropped that means you subtract another 5 from it which is -4-5
Answer:
The correct answer is -4 - 5.
Step-by-step explanation:
The original temperature is -4 degrees. Then, the temperature falls by 5 degrees. The temperature "falling" means that it is getting colder or that the temperature is getting lower. This lets us know that we need to use subtraction. The final answer is -4 - 5, which would give us the temperature of -9 degrees as the new temperature.
Hope this helps!
If you were to describe a rotation of triangle ABC what information would you need to include in your description
You would need to include the center of rotation. For many problems, the center is usually the origin (0,0). This is a default assumed center. Though the center could easily be any other point.
In addition, you also need the amount of rotation that is being applied (eg: 90 degrees).
The last bit of info you need is whether you're going clockwise or counterclockwise. For 180 degree rotations, it doesn't matter, but for everything else it does matter.
