If a rectangle is 12 meters with a width of 400 centimeters what is the perimeter
2 answers:
Answer:
32 meters
Step-by-step explanation:
The question gives measurements in different units. We need to make them the same.
Convert 400 centimeters into meters by dividing 400 by 100.
400 centimeters is 4 meters.
Formula for finding the perimeter of a rectangle:
<em>4 meters is the width and 12 meters is the length. </em>

Step-by-step explanation:
The given polynomial equation is
We perform the synthetic division as shown in the attachment by dividing by x-2.
This gives a remainder of 0 and a quotient of
This means the polynomial equation becomes:
We factor the quadratic term by splitting the middle term;
Collect common factors again:
The solution is:
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
