Answer:
0.9792
Step-by-step explanation:
Data provided in the question:
Average gross sales = $1,240
Standard deviation = $180
sample size = 40
Now,
standard deviation of sample average
=
=
= 28.46
Now,
z value for 1200 =
= -1.4,
and,
p value for (z = -1.4) = 0.0808
therefore,
P(average < $1200) = 0.0808
Thus,
probability that the average over the next 40 weekdays will exceed $1,200
= 1 - 0.808
= 0.9792
D. You can find a perpendicular line by finding the inverse equations (-(1/)2 x+3
Answer:
The least common multiple would be 105.
Step-by-step explanation:
You would do list out the multiples for each. Or multiply
Since 3 x 30 is 90, and 3 x 5 is 15, This is 105
And since 5 x 20 is 100, and 5 x 1 is 5, This is 105 as well
Also, since 7 x 10 is 70, and 7 x 5 is 35, This is 105.
The LCM is 105
Have a great Day!

Determine which coordinate fall in the right quadrant
First, we split the each quadrant into x and y axis
In the first:
x and y is +
In the second:
x is - and y is +
In the third
x and y are -
In the fourth
x is + and y is -
