Answer:

n = .25

Step-by-step explanation:

For the equation to be true, both sides must be equal.

20 * 4 * 3 * n = 5 * 12

240 * n = 60

n = 60/240

n = .25

A number picked at random from the numbers 1 through 15 is prime. This "question" is on my study guide for Unit 6 Probability an

Sphinxa [80]

Solution:

we are given that

A number picked at random from the numbers 1 through 15 is prime.

As we know the number between 1 and 15 which are primes are listed below

2,3,5,7,11,13.

Here total number of favourable outcomes are 6.

The numbers 1 through 15 are as below:

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15.

Here total number of possible outcoes are 15.

Hence the probability that if a number picked at random from the numbers 1 through 15 is prime $=\frac{6}{15}=\frac{2}{5}=0.40$

Hence the probability that if a number picked at random from the numbers 1 through 15 is prime is 0.4

Solve this for x. I have had 3 tries and can’t get the right answer.

Tanya [424]

Let's do both. For the first one, we can add 1 to both sides using the property of equality, and get 4x < -12. Then, we divide by 4, getting us x<-3. For the second, we subtract 3 from both sides to get -2x < 4. Then, we divide by -2 on both sides, but when we divide by a negative we have to switch the sign. So, we get x > -2. Hope this helps.

The probability of randomly selecting a name starting with the letter T from a bowl of 24 names is . Which of the following desc

lara31 [8.8K]

The probability of randomly selecting a name starting with the letter T from bowl of 24 names depends on the names that are in the bowl,. The number 24 says nothing about the names. There can be neither probability that the randomly selected name starts with T, if in the bowl none of the 24 names starts with T.
It could be also unlikely to select a name starting with T if there is a really small number of names in the bowl starting with T (for example 1 or 2 from 24). And it can be likely to chose a name that start with T if there are many names in the bowl starting with T.So, it is important to know the number of names in the bowl starting with T.

1/2(-9 + y)=2.5 solve for why. Please show me your steps

Oksi-84 [34.3K]

Answer:

Y = 14

Step-by-step explanation:

1/2(-9 + y) = 2.5

1/2 * -9 = -4.5

1/2 * y = 0.5y

-4.5 + 0.5y = 2.5

+4.5 +4.5

0.5y = 7

/0.5 /0.5

y = 14
