Answer:
It will take Winston 11 seconds to hop 44 meters and catch up to Tina
Step-by-step explanation:
Set up an equation where x represents the number of seconds:
Tina will be represented by s + 33 since she goes 1 m/sec and she has a 33 meter head start, and Winston will be 4s. We need to find when Winston will catch up, so we need an equal sign.
s + 33 = 4s
Solve for s:
s + 33 = 4s
33 = 3s
11 = s
= 11 seconds
Then, plug in 11 as s to find how many meters he will go:
s + 33
11 + 33 = 44
= 44 meters
Step-by-step explanation:
(1 point)
No, there isn't a more efficient way to solve this system.
Yes, a more efficient way is to multiply the first equation by 4, add to eliminate y, then solve for x.
Yes, a more efficient way is to multiply the first equation by −4, add to eliminate y, then solve for x.
Yes, a more efficient way is to multiply the first equation by −4, add to eliminate x, then solve for y.
Answer:
Step-by-step explanation:
Each 90° clockwise turn takes a point (x,y) and transforms it to (y,-x). For a 180° turn you would do this process twice in a row; for a 270° turn, three times in a row.
Answer: approximately normal
Step-by-step explanation:
1/2 Thinking about population shape and sample size
When a population is normally distributed, the sampling distribution of the sample mean x will also be normal regardless of sample size.
Since the distribution of distances is normal, the sampling distribution of the sample mean distance will also be normal.
2/2 Answer
The sampling distribution of the sample mean distance will be approximately normal.
Solution:
1) m is atleast 25
"at least" means greater then or equal to
Therefore,
2) p is less than 48
3) h is atmost 56
"at most" means less than or equal to
4) k is no greater than 9
Which means k is less than or equal to 9
5) w is no less than 0
Which means, w is greater than or equal to 0
