I assume it is the last one, 3n^2, because the degree is the exponent, which is two and the three is the coefficient, which is next to the variable, plus it is a monomial, so there is only one term, eliminating the first two, the third one is just reversed. Therefore, the answer should be the last one. Hope this helps. :)

A manufacturing firm tests job applicants. Test scores are normally distributed with a mean of 500 and a standard deviation of 5

Blababa [14]

Answer:

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = 0.0228

Step-by-step explanation:

Step(i):-

Given mean of the Population = 500

Given standard deviation of the Population = 50

Let 'X' be the random variable in normal distribution

Given X = 600

$Z = \frac{x-mean}{S.D} = \frac{600-500}{50} = \frac{100}{50} =2$

Step(ii):-

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = P(z≥2)

= 0.5 - A(2)

= 0.5 -0.4772

= 0.0228

Final answer:-

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = 0.0228

SOLVE PLEASE, FIND THE VALUE OF X! 7x/3+2=-15

nikklg [1K]

Answer:

${ \tt{ \frac{7x}{3} + 2 = - 15 }} \\ \\ { \tt{ \frac{7x + 6}{3} = - 15 }} \\ \\ { \tt{7x + 6 = - 15 \times 3}} \\ \\ { \tt{7x + 6 = - 45}} \\ \\ { \tt{7x = - 45 - 6}} \\ \\ { \tt{7x = - 51}} \\ \\ { \boxed{ \tt{x = - 7.3}}}$
