P(TeamA) = 0,43
P(Female) = 0,52
P(TeamA and Female) = 0,19
P(TeamA or Female) = ?
P(TeamA or Female) = P(TeamA) + P(Female) - P(TeamA and Female) <=>
P(TeamA or Female) = 0,43 + 0,52 - 0,19 <=>
P(TeamA or Female) = 0,76 or 76%
Answer:
107.5 cm
Step-by-step explanation:
find the length of the missing side of triangle which is 22.5 rounded then add all the sides together
A.

Since about 95% of a normal distribution falls within two standard deviations of the mean, that leaves 5% that lie without, with 2.5% lying to either side.

b.

About 68% of a normal distribution lies within one standard deviation of the mean, so this probability is about 0.68.
c. You're looking for

such that

Since

occurs for

, it follows that

So there's a probability of 0.10 for having a demand exceeding about 1328 pounds.
This could by seen as a ratio:
4:5
Add up the ratio. Then divide the money earned, by the ratio.
4 + 5 = 9
31.50 / 9 = 3.5
Then you times the individual hours by this.
4 x 3.5 = $14
5 x 3.5 = $17.5
So Jan earned $14
And Ted earned $17.50
