Answer:

150$

Step-by-step explanation:

In order to find the answer to this question you must find twenty-five percent of two-hundred.

50% of 100 = 50

100% of 100 = 100

100% of 200 = 200

50% of 200 = 100

25% of 200 = 150

= 150$

Hope this helps.

lord [1]

Answer: 3 13/24

Step-by-step explanation:

Turn 7 1/6 into an Improper Fraction:

43/6 - 3 5/8

Turn 3 5/8 into an Improper Fraction:

43/6 - 29/8

Subtract:

43/6 - 29/8= 85/24

Turn 85/24 into a Mixed Number (Final Step):

85/24 = 3 13/24

Answer:

3 13/24

Which triangle side lengths form a right triangle? Choose all that apply. 5, 6, 7 6, 8, 14 8, 15, 17 10, 12, 15 15, 20, 25 16, 1

yuradex [85]

Answer:

C. 8, 15, 17

E. 15, 20, 25

Step-by-step explanation:

You need to take the 2 smaller numbers as in 8 and 15 square it, so 8x8= 64 and 15x15= 225 and then add 64+225= 289 and 17x17=289 so 289=289 ✔

Again square 15 and 20, 15x15=225 and 20x20=400 add them 225+400=625

and 25x25=625 so 625=625 ✔

Hope this helped and good luck!

Suppose the probability that a softball player gets a hit in any single at-bat is 0.300. Assuming that her chance of getting a h

Ksivusya [100]

Answer:

$P(X=4)=(1-0.3)^{4-1} 0.3 = 0.103$

The probability that she will not get a hit until her fourth time at bat in a game is 0.103

Step-by-step explanation:

Previous concepts

The geometric distribution represents "the number of failures before you get a success in a series of Bernoulli trials. This discrete probability distribution is represented by the probability density function:"

$P(X=x)=(1-p)^{x-1} p$

Let X the random variable that measures the number os trials until the first success, we know that X follows this distribution:

$X\sim Geo (1-p)$

Solution to the problem

For this case we want this probability

$P(X=4)$

And using the probability mass function we got:

$P(X=4)=(1-0.3)^{4-1} 0.3 = 0.103$

The probability that she will not get a hit until her fourth time at bat in a game is 0.103
