Mean equals average
So 8 plus 10 equals 18
18 divided by 2 is 9
Mean is 9
Answer:
Option 4. x = 0
Step-by-step explanation:
we know that
The rule of the reflection of a point across the y-axis is equal to
(x,y) -----> (-x,y)
The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the y-value the same
The coordinates of triangle PQR are
P(1, 4), Q(3, 6), and R(5, 2)
Applying the rule of the reflection across the y-axis we have
P(1, 4) -----> P'(-1, 4)
Q(3, 6) ----> Q'(-3, 6)
R(5, 2)----> R'(-5, 2)
The reflection line is the y-axis
Remember that the equation of the y-axis is x=0
therefore
The equation of the reflection line is x=0
A) hexagonal prism......................................................................
The answer is 18^8 because u add exponents
<em>If a rectangular prism has a volume of 470.40 cm</em><span><em>³, and the length and width is equal to 6.4 and 9.8, we will find the height by using some inverse operations. We will use the variable h to represent height</em>
<em>Length x Width x Height = Volume</em>
<em>6.4 cm • 9.8 cm `• h = 470.40</em>
<em>470.40 ÷ (9.8 x 6.4)</em>
<em> = 470.40 ÷ 62.72</em>
<em> = 7.5</em>
<em>Check Answer:</em>
</span><em>Length x Width x Height = Volume</em>
<em>6.4 cm • 9.8 cm `• 7.5 = 470.40</em>
<u>Answer: 7.5 cm</u>
