What is -121-4x=39+6x
vodka [1.7K]
So we're trying to solve for x. To do this we need to balance the equation.
-121 -4x = 39 + 6x
Get x on one side; add 4x to both sides.
-121 = 39 + 10x
Subtract 39 from both sides (remember when subtracting a negative to a negative, it's basically just adding with negative signs).
-160 = 10x
Divide both sides by 10.
x = -16.
Hope this helps!

When you send out a resume, the probability of being called for an interview is 0. 40. what is the probability that the first in
Kipish [7]

The probability that the first interview occurs on the fifth resume that you sent is 0.2592.

According to the given question.

The probability of being called for an interview, p = 0.40.

So, the probability of not being called for an interview, q = 1 - 0.40 = 0.60

As we know that binomial distribution summarizes the number of trials, or observations when each trial has the same probability of attaining one particular value. The binomial distribution determines the probability of observing a specified number of successful outcomes in a specified number of trials.

Therefore, the probability that the first interview occurs on the fifth resume that you send out

= ^{5} C_{1} (0.40)^{1} (0.60)^{4}

= 5(0.40)(0.1296)

= 0.2592

Hence, the probability that the first interview occurs on the fifth resume that you sent is 0.2592.
