Answer:

between 564 gr and 636 gr

Step-by-step explanation:

If the percent error is 6% (0.06 in decimal form) of 600 gr, then the error is :

0.06 * 600 gr = 36 gr

Therefore the actual mass of the book is between 600 - 36 = 564 gr and 600  + 36 = 636 gr.

P = 14.7e-0.21x, where x is the number of miles above sea level. To the nearest foot, how high
AlladinOne [14]

9514 1404 393

Answer:

  13064 feet

Step-by-step explanation:

We can rewrite the formula so that x is in feet. Equating the new formula to 8.743 PSI, we have ...

  8.743 = 14.7e^(-0.21x/5280)

Dividing by 14.7 and taking natural logs, we have ...

  ln(8.743/14.7) = -0.21x/5280

Multiplying by the inverse of the coefficient of x gives ...

  x = 5280·ln(8.743/14.7)/-0.21 ≈ 13064.0806

The peak of the mountain is about 13,064 feet high.

What is the y-intercept of a line that has a slope of –3 and passes through point (–5, 4)? –17 , –11 , 7 , 19
Sindrei [870]

Hey there! :)

Answer:

b = -11.

Step-by-step explanation:

Create an equation in slope-intercept form to solve for the intercept:

y = mx + b

Plug in the slope and point values:

4 = -3(-5) + b

Simplify:

4 = 15 + b

Solve for b:

-11 = b

b represents the y-intercept, therefore:

y-intercept = -11

A large manufacturing firm tests job applicants who recently graduated from college. The test scores are normally distributed wi
Sergeeva-Olga [200]

Answer:

The lowest score a college graduate must be 577.75 or greater to qualify for a responsible position and lie in the upper 6%.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 500

Standard Deviation, σ = 50

We are given that the distribution of test score is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.06.

P(X > x)  = 6% = 0.06

P( X > x) = P( z > \displaystyle\frac{x - 500}{50})=0.06  

= 1 - P( z \leq \displaystyle\frac{x - 500}{50})=0.06  

=P( z \leq \displaystyle\frac{x - 500}{50})=1-0.06=0.94  

Calculation the value from standard normal z table, we have,  

P(z < 1.555) = 0.94

\displaystyle\frac{x - 500}{50} = 1.555\\x = 577.75  

Hence, the lowest score a college graduate must be 577.75 or greater to qualify for a responsible position and lie in the upper 6%.
