Answer:
y=7
Step-by-step explanation:
When ever the slope is 0, the line is completely flat. This means that the equation has the same y for every point.
The y on the point given is 7, therefore the answer is y=7.
Answer:
14 balls will be pink out of 21 balls.
Step-by-step explanation:
Given that:
2 out of every 3 balls are pink in a multi color package.
Ratio of pink balls to balls drawn = 2:3
Number of balls in package = 21 balls
Number of pink balls = x
Ratio = x:21
This is a proportional relationship
2 : 3 :: x : 21
Product of mean = Product of extreme
3x = 21*2
3x = 42
Dividing both sides by 3
Hence,
14 balls will be pink out of 21 balls.
Answer:
W = 3
Step-by-step explanation:
2(W - 1) + 8 = 6(2w - 4)
2w - 2 + 8 = 12w - 24
2w + 6 = 12w - 24
6 = 10w - 24
30 = 10w
3 = W

Empirical rule dictates that, in a Bell-shaped distribution, 95% of data lies within 2 standard deviation on either side of the mean.
Therefore,
Lower value = mean-2SD = 70-2*8 = 70-16 = 54
Upper value = mean+2SD = 70+2*8 = 70+16 = 86
Then, 95% of the data lies between $54 and 84. These values can also be taken as the true mean of the population considering 95% confidence when sample mean has been calculated. In this regard, 2SD can be regarded as the margin error.
