Answer:
81.85%
Step-by-step explanation:
We have the following information:
mean = m = 52000
standard deviation = sd = 12000
a = 40000
b = 76000
we need to find the probability between a and b, that is:
P (a <x <b) = P (40,000 <x <76000)
P [(40000 - m) / sd <(x - m) / sd <(76000 - m) / sd]
replacing
P [(40000 - 52000) / 12000 <z <(76000 - 52000) / 12000]
P (-1 <z <2)
P (z <= -1) - P (z <= 2)
We look for this value of z, in the attached table:
0.9772 - 0.1587
P = 0.8185
In other words, the probability is 81.85%
Answer:
<em>D. In a parallelogram, opposite angles are congruent.</em>
Step-by-step explanation:
In each case, she measures two opposite angles, and they are congruent.
D. In a parallelogram, opposite angles are congruent.
Answer:
A straight line.
Step-by-step explanation:
An arithmetic sequence has a common difference so the slope of the graph will be constant, giving a straight line.
Jan. profit..... 5625.14
feb..loss... - 4250.35
march..profit...1475.55
add the profits and subtract the losses...if the result is positive, then the company made a profit....if the result is negative, then the company had a loss.
(5625.14 + 1475.55) - 4250.35 = 7100.69 - 4250.35 = 2850.34.....as u can see, the result ended in a positive number....so, in the 3 month period, the company made a profit of $ 2850.34 <==
