5 ft because 3 squared is 9 and 4 squared is 16 9+16=25 25 squared is 5
Answer:
1/5
Step-by-step explanation:
We can find the slope using the slope formula
m = (y2-y1)/(x2-x1)
= (3-2)/(4 - -1)
(3-2)/(4+1)
1/5
No because 4/1 does not equal to 9/4 or 16/9

First, lookup a standard normal table and see what the z-score is for 0.025 (one half of 100% - 95%) to allow for equal sized tails. You should find that the z-score is 1.96. That means that 95% of the time, the value should be within 1.96 standard deviations of the mean. Now let's calculate the standard deviation.
800 is 800 - 1200 = -400 to the left of the mean of 1200.
1600 is 1600 - 1200 = 400 to the right of the mean of 1200.
So we are an equal distance of 400 on both sides of the mean. And we know from the z-score of 1.96, that we're 1.96 standard deviations from the mean. So a little division will give us the standard deviation. Which is:
400 / 1.96 = 204.0816327
So the standard deviation of the light bulbs is 204</span>
Answer:
The median is -8°F
Step-by-step explanation:
Attached Table.
The median is the "middle" value from all the numbers arranged from least to greatest.
Looking at the table, we need to arrange the numbers (first week numbers) from least to greatest.
-31, -29, -9, -8, 3, 4, 6
There are 7 numbers and the middle number is the 4th one, which is -8
The median is -8°F
