A parallelogram has 4 sides, 2 of them are parallel to each other along with the others.
You can see how far (from the middle of the quadrilateral) is one end of the line and then indicate how far the other end is. If those numbers are equal to the other lines distance then they are parallel

Answer:

The answer is 3 , 1 , 2 .

Step-by-step explanation:

I will give an example.

e.g.

x² + 3x + 2

Step 3 :

Set the equation equal to zero :

x² + 3x + 2 = 0

Step 1 :

Completely factor the equation :

x² + x + 2x + 2 = 0

x(x+1) + 2(x+1) = 0

(x+2)(x+1) = 0

Step 2 :

Set each factor equal zero and then solve for the variable :

(x+2)(x+1) = 0

x + 2 = 0

x = -2

x + 1 = 0

x = -1

The time that it takes a randomly selected job applicant to perform a certain task has a distribution that can be approximated b
storchak [24]

Answer:

A task time of 177.125s qualify individuals for such training.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by

Z = \frac{X - \mu}{\sigma}

After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X. Subtracting 1 by the pvalue, we This p-value is the probability that the value of the measure is greater than X.

In this problem, we have that:

A distribution that can be approximated by a normal distribution with a mean value of 145 sec and a standard deviation of 25 sec, so \mu = 145, \sigma = 25.

The fastest 10% are to be given advanced training. What task times qualify individuals for such training?

This is the value of X when Z has a pvalue of 0.90.

Z has a pvalue of 0.90 when it is between 1.28 and 1.29. So we want to find X when Z = 1.285.

So

Z = \frac{X - \mu}{\sigma}

1.285 = \frac{X - 145}{25}

X - 145 = 32.125

X = 177.125

A task time of 177.125s qualify individuals for such training.

mihalych1998 [28]

Answer:

(5 , 7)

Step-by-step explanation:

let a = the number of adult tickets

let c = the number of children tickets

then we have to solve the following system

a + c = 12

14.5a + 9c = 135.5

we proceed by Substitution:

              c = 12 - a

14.5a + 9c = 135.5

After some calculations we find

a=5 and c=7
