Answer: 18.96

Step-by-step explanation:

From the question, Tremaine scored 54 three-point goals, 84 two-point field goals, and 106 free throws. The total point scored will be:

=(54 × 3) + (84 × 2) + (106 × 1)

= 162 + 168 + 106

= 436 points

The number of points scored on average per game will then be:

= 436 / 23

= 18.96 points per game

Answer:

D

Step-by-step explanation:

The degree of a polynomial is determined by the largest exponent of a term within the polynomial.

Given

7x³ + 4x - 5 + 8[tex]x^{5}[/tex]

The term with the largest exponent is 8[tex]x^{5}[/tex] with exponent 5

Thus the polynomial is of degree 5 → D

The mean age of 5 people in a room is 26 years. A person enters the room. the mean age is now 33 so the age of the person 68 who entered the room.

In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply put, the mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally. The three most frequently employed measures of central tendency are the mean, median, and mode. The total values provided in a datasheet must be added, and the sum must be divided by the total number of values in order to determine the mean. When all of the values are organized in ascending order, the Median is the median value of the given data. While the number in the list that is repeated a maximum of times is the mode.

So According to the question, the Mean of  5 people in a room =26

When a person enters the room mean age becomes = 33

The sum of their age is = 5*6 =130

when other persons enter the room means the total person becomes =6

and the sum of their age after another person enters the room= [tex]x+130[/tex]

where x is the age of the other person entering the room.

so, mean = 33= (130+x)/6

 then, 130+x=6*33

   And,130+x=198

so,x=198-130  =68

Answer:

The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.

Step-by-step explanation:

It's possible because they cut cakes into different number of slices.

You know that Luke, Kira and Ali each served [tex]\frac{2}{3}[/tex] of their own cake and Luke served 4 slices, Kira served 6 slices and Ali served 8 slices.

Being x the whole slices of cake, and if Luke served [tex]\frac{2}{3}[/tex] of his cake, which are 4 slices, the whole slices of cake of Luke is:

[tex]\frac{2}{3}*x=4 slices[/tex]

Solving:

x= 4 ÷[tex]\frac{2}{3}[/tex]

x= 6

Then, whole slices of Luke's cake is 6.

Performing the same approach for Kira you get:

[tex]\frac{2}{3}*x=6 slices[/tex]

x= 6 ÷[tex]\frac{2}{3}[/tex]

x= 9

Then, whole slices of Kira's cake is 9.

Finally, performing the same approach for Ali you get:

[tex]\frac{2}{3}*x=8 slices[/tex]

x= 8 ÷[tex]\frac{2}{3}[/tex]

x= 12

Then, whole slices of Ali's cake is 12.

The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.

Answer:

$112.95

Step-by-step explanation:

Use the simple interest formula, I = prt

Plug in the initial amount, interest rate, and number of years

I = prt

I = (1506)(0.025)(3)

I = 112.95

So, the interest created in 3 years is $112.95

Answer:

5 yr and 39 yr

Step-by-step explanation:

Let x = the age of the younger

then 7x + 4 = the age of the older

Now x + 7x + 4 = 44

8x + 4 = 44

8x = 40

x = 5

7x + 4 = 7(5) + 4 =  35 + 4 = 39

Check:  5 + 39 = 44

Answer:

The person's angular momentum will be double

Step-by-step explanation:

Let

Speed of person=v

Mass of person=m

Radius=r

Speed of person=2v

We have to find the person's angular momentum when the speed of person is double and all else remains same.

We know that

Angular moment ,L=mvr

Using the formula

Angular momentum of person when speed 2v

L'=m(2v)r

[tex]\frac{L'}{L}=\frac{m(2v)r}{mvr}=2[/tex]

[tex]L'=2L[/tex]

Hence, the angular moment of person will be double when the speed of person is double.
