Answer:
a) z = -0.358
b) z = 0.358
Step-by-step explanation:
We are given a standard normal distribution.
a) We have to find the value of z such that the proportion of observations that are less than z in a standard normal distribution is 0.36.
That is,
This value will be calculated with the help of a standard normal table.
From standard normal table we have,
Thus, for z equal to -0.358 the proportion of observations that are less than z in a standard normal distribution is 0.36
b) We have to find the value of z such that 36% of all observations from a standard normal distribution are greater than z.
This value will be calculated with the help of a standard normal table.
Calculation the value from standard normal z table, we have,
Thus, 36% of all observations from a standard normal distribution are greater than z equal to 0.358
Answer:
108 in
Step-by-step explanation:
The figures are similar, so if we find a relation of the area and the diagonal in rectangle 1 we can apply it to rectangle 2.
rectangle 1 :
72/x=12
x=6
therefore
72/6=12
rectangle 2:
A/x=18
A/6=18
6*18=108
A=108 in

Find the lateral area of a cylinder with the given measurements. Use 3.14 for pi and round your answer to the nearest tenth.
height: 15 centimeters
radius: 9 centimeters
Question 11 options:
787.3 cm2
1356.5 cm2
847.8 cm2
889.9 cm2
So we know the formula for the lateral area of a cylinder is:
AL=2πrh
now all we have to do is put the given value in place of the correct variable then solve like so:
AL=2*3.14*9*15
AL= 847.8 cm2
so the answer is the third option
hope this helps

Answer: add (+2) to each side so add 2 to -2 and also add 2 to 60 which you will end up with 3x=62 and from there divide each side by 3 so 3 divided by 3 (which is x) and 62 divided by 3 (which is 20.6) so x=20.6
Have a great day :)
Answer:
414 - 223
= 191
Step-by-step explanation:
414-223 = 191 he has 191 paint left
to check the answer we do
191 + 223 = 414 our answer is correct
