Answer:
40is the correct answer right
Answer:
0
Step-by-step explanation:
The question lacks the graph to be able to solve it, I was doing a little research and I could find the graph which I will attach:
Already with the figure we can solve the question.
We have that the average exchange rate in this case would only take the normal slope between those 2 lines
. Furthermore we know that the slope (m) is given by:
m = (y2-y1) / (x2 - x1)
From the graph we have to:
y2 = 0
y1 = 0
x2 = 5
x1 = 3
we replace:
m = (0-0) / (5 - 3)
m = 0
Therefore the average rate is 0.
Answer:
Mai is moving faster than Priya.
Step-by-step explanation:
It is given that Mai traveled 15 meters in 6 seconds.

The speed Mai is

Priya travels 22 meters in 10 seconds. Speed of Priya is

Since speed of Mai is more than the speed of Priya, therefore Mai is moving faster than Priya.
Answer:
0.0735,0.0179,0.7026
Step-by-step explanation:
Given that a simple random sample of size nequals 49 is obtained from a population with mu equals 78 and sigma equals 28.
Sample size = 49
Population mean = 78
Population std deviation = 28
Std error of sample mean = 
a)
: N(78, 4)
b) 
(by converting to Z and finding value from Z table)
c) P (x overbar less than or equals 69.6 )
=
d) P (75.8 less than x overbar less than 88 )
=
Answer:
You will need four runners.
Step-by-step explanation:
If you multiply 1/16 by four you will get 4/16, which is simplified to 1/4
