Kala has scored 18, 22, 19, and 26 points in her four basketball games so far. How many
points does she need to score in her next game so that her average (mean) is 21 points per
game?
Answer:
Kala must score 20 points in her fifth game.
Step-by-step explanation:
The mean or average of a set is given by:
[tex]\displaystyle \overline{x} = \frac{\text{sum of data values}}{\text{number of data values}}[/tex]
(Note: the symbol used to denote the mean is known as "x-bar.")
We want to find the points (let the unknown value be a) Kala needs to score in her fifth game such that her average score is 21 points per game.
In other words, her total score so far plus a all over five (five games in total) must equal 21:
[tex]\displaystyle (21) = \frac{(18) + (22) + (19) + (26) + a}{5}[/tex]
Solve for a. Multiply and combine like terms:
[tex]\displaystyle 105 = 85 + a[/tex]
Subtract. Hence:
[tex]a = 20 \text{ points}[/tex]
In conclusion, Kala must score 20 points in her fifth game.
Answer:
Answer :-
We know that
Average = Sum of observation/Total observation
Let the unknown observation be x
18 + 22 + 19 + 26 + x/5 = 21
85 + x/5 = 21
85 + x = 21 × 5
85 + x = 105
x = 105 - 85
x = 20

Natasha's rectangle measures 4 1/2 units by 2 1/4 units. What is its area?
Answer:
Answer: 49/6units^{2}49/6units
2
Step-by-step explanation:
You can convert from mixed number to fractions as following:
2 1/3=((2*3)+1)/3=7/3 units
3 1/2=((3*2)+1)/2=7/2 units
Then you can calculate the area of the rectangle as you can see below:
\begin{gathered}Area=lenght*width\\Area=7/2units*7/3units\\Area=49/6units^{2}\end{gathered}
Area=lenght∗width
Area=7/2units∗7/3units
Area=49/6units

Find angle A and angle E
Answer:
m∠A = 50°
m∠E = 50°
Step-by-step explanation:
7x - 17 and 2x + 8 are same side exterior angles. They have a sum of 180°.
7x - 17 + 2x + 8 = 180
9x - 9 = 180
9x = 189
x = 21
∠A and 7x - 17 are supplementary. ∠E and 2x + 8 are vertical angles.
m∠A + 7x - 17 = 180
m∠A + 7(21) - 17 = 180
m∠A + 147 - 17 = 180
m∠A + 130 = 180
m∠A = 50
m∠E = 2x + 8
m∠E = 2(21) + 8
m∠E = 42 + 8
m∠E = 50

Step-by-step explanation:
[tex]2x - 8y + 3 {x}^{2} + 7y - 12x[/tex]
[tex]2x - 12x = (2 - 12)x = - 10x[/tex]
[tex] - 10x - 8y + 3 {x}^{2} + 7y[/tex]
