Answer:

z = 6

Step-by-step explanation:

9=1.5z  (divide both sides by 1.5)

9 / 1.5 = 1.5z / 1.5  (rearrange)

z = 9/1.5

aksik [14]

Answer:

Step-by-step explanation:

Given that the television show Degenerate Housewives has been successful for many years. That show recently had a share of 18, meaning that among the TV sets in use, 18% were tuned to Degenerate Housewives.

Each household is independent of the other and there two outcomes.

X no of households that are tuned to Degenerate Housewives. is Bin (12, 0.18)

the probability that none of the households are tuned to Degenerate Housewives. P(none) =_______0.0924_____

the probability that at least one household is tuned to Degenerate Housewives. P(at least one) = ____1-0.0924 = 0.9076______

the probability that at most one household is tuned to Degenerate Housewives. P(at most one) = _____0.3359______

If at most one household is tuned to Degenerate Housewives, does it appear that the 18% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Degenerate Housewives unusual?)

No 33% is not unusual.

7 times as much as the sum of 1/3 and 4/5
Zanzabum
Well first we want to divide 1 by 3 , which is 0.3  ,  Now we need to divide 4 by 5 which is 0.8 . 

We have our answers but 7 needs to be added by their sum so lets put them together by adding them : 0.3 + 0.8 = 1.1.

Now lets add 7 and 1.1 all together , which is 8.1.

I hope this helps you a lot :)

just olya [345]

Answer:The first one is 2.333333333

Step-by-step explanation:Simplifying

5(2 + -1j) + (2j + -3) = 0

(2 * 5 + -1j * 5) + (2j + -3) = 0

(10 + -5j) + (2j + -3) = 0

Reorder the terms:

10 + -5j + (-3 + 2j) = 0

Remove parenthesis around (-3 + 2j)

10 + -5j + -3 + 2j = 0

Reorder the terms:

10 + -3 + -5j + 2j = 0

Combine like terms: 10 + -3 = 7

7 + -5j + 2j = 0

Combine like terms: -5j + 2j = -3j

7 + -3j = 0

Solving

7 + -3j = 0

Solving for variable 'j'.

Move all terms containing j to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + -3j = 0 + -7

Combine like terms: 7 + -7 = 0

0 + -3j = 0 + -7

-3j = 0 + -7

Combine like terms: 0 + -7 = -7

-3j = -7

Divide each side by '-3'.

j = 2.333333333

Simplifying

j = 2.333333333
