14 less than 8 times a number is 3 more than 4 times the number. What is the number?

e-lub [12.9K]

Answer:

x = 17/4

Step-by-step explanation:

Let x = the number

8x-14 = 4x+3

Subtract 4x from each side

8x -14-4x = 4x+3-4x

4x-14 = 3

Add 14 to each side

4x-14+14 = 3+14

4x = 17

Divide by 4

4x/4 = 17/4

x = 17/4

If a procedure meets all of the conditions of a binomial distribution except the number of trials is not fixed, then the geomet

natima [27]

Answer:

Given p = 0.07 as the probability that someone is a universal donor

In case of Geometric Distribution, Probability of getting the first success on nth trial is given by

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

where p is the probability of success on any one trial and (1-p) shows the probability of failure.

So the probability of the first subject to be a universal blood donor will be the seventh person is

$P (X=7) = 0.07 (1-0.07) ^ {7-1} = 0.07 (0.93) ^ 6 = 0.07*0.647 = 0.0453$

So the final probability is 0.0453

(Mhanifa) please solve this question thank you!

ivanzaharov [21]

Answer:

Option A

Step-by-step explanation:

A'B' is 1/2 times the AB as the scale factor is 1/2.

<u>Find the length of AB using distance formula.</u>

AB = $\sqrt{(4 - 2)^2 + (4-0)^2} = \sqrt{20} = 2\sqrt{5}$

A'B' = 1/2*2 $\sqrt{5} = \sqrt{5}$

Correct choice is A
