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 y co-ordinate is 9
Step-by-step explanation:
We simplify the expression given by the formula;
Answer:
-7x - 4
Step-by-step explanation:
(-7 x 2) - 6x + 9 + (-3 x 2) - x + 7
-14 - 6x + 9 - 6 - x + 7
-7x - 4
