Please help Solve 5(2x - 3) = 5x - 10 for c <br><br> A) 2<br><br> B) 1<br><br> C) 0<br><br> D) -1
bixtya [17]

Answer:

B

Step-by-step explanation:

Use distributive property:

5(2x - 3) = 5x - 10

10x - 15 = 5x - 10

Isolate the variable:

10x = 5x - 10 + 15

10x = 5x + 5

10x - 5x = 5

5x = 5

x = 1

Ludmilka [50]

Answer:

the probability that a sample of the 35 exams will have a mean score of 518 or more is <em> 0.934 </em>or<em> 93.4%</em>.

Step-by-step explanation:

This is s z-test because we have been given a sample that is large   (greater than 30) and also a standard deviation. The z-test compares sample results and normal distributions. Therefore, the z-statistic is:

(520 - 518) / (180/√35)

= 0.0657

Therefore, the probability is:

P(X ≥ 0.0657) = 1 - P(X < 0.0657)

where

  • X is the value to be standardised

Thus,

P(X ≥ 0.0657) = 1 - (520 - 518) / (180/√35)

                       = 1 - 0.0657

                       = 0.934

Therefore,  the probability that a sample of the 35 exams will have a mean score of 518 or more is <em>0.934 or 93.4%</em>.
