Answer:
Well for Part A-
List the temperatures from least to greatest; anything under 0 degrees is the lowest.
-6.1
-2.5
-0.4
3.4
And for Part B-
You can use a number line to order the temperatures because it's a good way to sort which ones are the lowest and highest easily.
x+3<8
8-3 =5
X<5
any number less than 5 will work
Simple,
1/2 of 60
re-write it as 0.5 of 60 aka 0.5*60
which is 0.5*60=30
Do the same with 1/2 of 24.
0.5 of 24
0.5*24=12.
Thus, it's not the same because they are different numbers and different number give you different answers.
Complete question :
The GPAs of all students enrolled at a large university have an approximately normal distribution with a mean of 3.02 and a standard deviation of .29.Find the probability that the mean GPA of a random sample of 20 students selected from this university is 3.10 or higher.
Answer:
0.10868
Step-by-step explanation:
Given that :
Mean (m) = 3.02
Standard deviation (s) = 0.29
Sample size (n) = 20
Probability of 3.10 GPA or higher
P(x ≥ 3.10)
Applying the relation to obtain the standardized score (Z) :
Z = (x - m) / s /√n
Z = (3.10 - 3.02) / 0.29 / √20
Z = 0.08 / 0.0648459
Z = 1.2336940
p(Z ≥ 1.2336) = 0.10868 ( Z probability calculator)
