Answer:
a. 0.7123
b. 0.1151
c. 0.0708
d. 0.6368
e. 0.7058
Step-by-step explanation:
- the area to the right of z* can be stated as P(z<z*), and corresponding probability of z* on z-table gives the result.
a. The area to the left of z = 0.56 = P(z<0.56) = 0.7123
b. The area to the right of z = 1.20 =P(z>1.20)= 1- P(z<1.20)= 1-0,8849=0.1151
c. The area to the left of z = −1.47 = P(z<-1.47)= 0.0708
d. The area to the right of z = −0.35 =P(z>-0.35) = 1-P(z<-0.35)=1-0,3632=0.6368
e. P(-1.39<z<0.80) = P(z<0.80) - P(z<-1.39) = 0.7881-0.0823 = 0.7058
Answer:
The student took 28 classes
Step-by-step explanation:
What I did was minus $15 from the $687 total, cause $15 is only a one time registration fee, then 687-15=672, so then I divided 672 by the cost per class, so $24, 672 divided by 24 equals to 28, so the student took 28 classes.

Answer:
Number of stars: 2+2+2+2+2+2
=6×2
Step-by-step explanation:
The stars are added in pairs of two. The pair that is 2+2+2+2+2 is five groups of 2 or 2 groups of five.
Since another pair of two wad added, there is one more pair. Instead of 5×2
Which means 5 groups of 4, it is not 6 groups of 2. I hope I helped you! Have a good day :3
