Answer:
28 units squared
Step-by-step explanation:
It becomes a lot easier if you just try to plot the points on an axis, but i'll try to explain.
A and B are x-intercepts and the bottom two corners of the rectangle. C and D are the top two corners of the rectangle. Like any other case, to find the area, you need just two things:
1) height
2) width
To find the width:
Consider the distance between A and B - the bottom 2 corners. The coordinates are (2,0) and (6,0). Since we are trying to work out the width, just worry about the x-values. So, 6-2 = 4 and that is the width.
To find the height:
We'll take coordinates B and C - the bottom and top right corners of the rectangle. Coordinates are (6,0) and (6,7). Since we are trying to work out the height, just look at the y-values. So, 7 (top corner) - 0 (bottom corner) = 7, which is the height.
To figure out area:
Just multiply width by height, so:
4 x 7 = 28
And the area is 28 units squared. Change the units into whatever unit of measurement they give you (m, cm, mm etc.)
Hope this helped :)
Answer:
c. 99.72% of the time the random variable assumes a value within plus or minus 1 standard deviation of its mean
Step-by-step explanation:
In a normal distribution, the shape is bell-shaped; this means it is symmetric.
The area under a normal distribution will always be equal to 1.
The mean, median and mode in a normal distribution are equal.
However, the data assumes values within 1 standard deviation above or below the mean 68% of the time, not 99.72% of the time. This is the characteristic that doesn't fit.
Given, Sylvie needs $110 for a concert ticket.
Sylvie has $16.
Her hourly earnings = $h
Sylvie is working 10 hours at her job.
She is getting in 1 hour = $h
So, 10 hours she will get = $ = $
So the total amount she has now = $16 + $(10h) = $()
So we can write the equation as,
We can move 16 to the left side also. 16 is added to the right side. We can move it by using reverse operation of addition. Reverse operation of addition is subtraction. So we will subtract 16 from both sides. Subtracting 16 we will get,
We have got the required answer.
To find Sylvie's hourly income the correct options are option A and option D.
First one A second one C third one d 4th one E
Answer:
Step-by-step explanation:
1/2y - 5/8y = 4/8y - 5/8y = -1/8y
3/4 - 7/8 = 6/8 - 7/8 = -1/8
-1/8y - 1/8 =
-y/8 - 1/8 =
