Answer:
It is: (f(2) - f(0))/(2 - 0)
f(2) = 250(0.5)(2) = 250
f(0) = 250 (0.5)(0) = 0
So: (250 - 0)/(2 - 0) = 250/2 = 175
The average rate of change is 175.
Step-by-step explanation:
The complete question in the attached figure
Let
Z---------------- > number of zacks stamps collections <span>for a stamp show
</span>T---------------- > number of teri's stamps collections <span>for a stamp show
</span>P--------------- > number of pacos stamps collections for a stamp show
we know that
Z=(3/10)*30-----------> Z=9
T=(5/6)*18------------ > T=15
P=(3/8)*24------------->P=9
the answer is
number of zacks stamps collections for a stamp show was 9
number of teri's stamps collections for a stamp show was 15
number of pacos stamps collections <span>for a stamp show </span>was 9
In their display were 33 stamps
Answer:
irrational number, nonrepeating decimal
Step-by-step explanation:
Answer:
6 : 1
Step-by-step explanation:
Given the ratio
12 : 2 ( divide both parts by 2 )
= 6 : 1 ← in the form n : 1
Answer:
The correct answer is option 'a' : 120 is more than 2.5 standard deviations above the expected value.
Step-by-step explanation:
For an exponential distribution we have
The expected value μ = 80
No of trails n = 200
Thus we have

The deviation is related to expected value and probability as

Thus the values between the given deviation is

Now since 120 successes are out of the range of [62.75,97.25] thus 120 is more than the expected value.
