Answer:
12.08
Step-by-step explanation:
For each sunflower, there are only two possible outcomes. Either it germinates, or it does not. The probability of a sunflower germinating is independent of other sunflowers. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The standard deviation of the binomial distribution is:
Seventy-six percent of sunflower seeds will germinate into a flower
This means that 
Samples of 800:
This means that 
The standard deviation for the number of sunflower seeds that will germinate in such samples of size 800 is:
<span>Y=2/3x+3 so slope = 2/3
</span><span>2x-3y=8
3y = 2x - 8
y = 2/3x - 8/3 so slope = 2/3
both equations have same slope = 2/3
so answer: </span><span>parallel</span>
Answer:
- 9 easy
Step-by-step explanation:
go ahead easiest thing ever lol
The perimeter of a rectangle:
P = 2 L + 2 W
where L is the length and W is the width.
The area of a rectangle:
A = L x W
7/10 = L x 4/5
L = 7/10 : 4/5 = 7/10 * 5/4
L = 7/8 in
P = 2 * 4/5 + 2 * 7/8 = 8/5 + 14/8 = 64/40 + 70/40 = 134/40 = 3 14/40 =
= 3 7/20 < 3 1/2
Answer:
A silver line is long enough to outline the stone.
Answer:
-3x + y = 8.
3y = 9x.
Step-by-step explanation:
To find the slope of the lines we convert to slope-intercept form, which is
y = mx + c (m is the slope.)
The slope of y = 3x + 5 is therefore 3.
Parallel lines have the same slope.
Finding the slope of the given lines:
-3x + y = 8
y = 3x + 8 - slope is 3 so this is parallel to y = 3x + 5.
3y = 9x
Divide through by 3:
y = 3x - so this is also parallel to 3x + 5.
y = -jx The slope is -j so it is not parallel.
16x + 2y = 12
2y = -16x + 12
y = -8x + 6 - Not parallel.
