Answer:

Third option.

Step-by-step explanation:

5-2\left(3x-9\right)=-1

Use the distributive law: a(b-c)=ab-ac

5-2\times3x-\left(-2\right)\times9=-1

Double negative = Positive

5-6x+18=-1

A manufacturer produces bearings, but because of variability in the production process, not all of the bearings have the same di
Lena [83]

Answer:

Proportion of all bearings falls in the acceptable range = 0.9973 or 99.73% .

Step-by-step explanation:

We are given that the diameters have a normal distribution with a mean of 1.3 centimeters (cm) and a standard deviation of 0.01 cm i.e.;

Mean, \mu = 1.3 cm            and           Standard deviation, \sigma = 0.01 cm

Also, since distribution is normal;

                 Z = \frac{X -\mu}{\sigma} ~ N(0,1)

Let X = range of diameters

So, P(1.27 < X < 1.33) = P(X < 1.33) - P(X <=1.27)

  P(X < 1.33) = P( \frac{X -\mu}{\sigma} < \frac{1.33 -1.3}{0.01} ) = P(Z < 3) = 0.99865

  P(X <= 1.27) = P( \frac{X -\mu}{\sigma} < \frac{1.27 -1.3}{0.01} ) = P(Z < -3) = 1 - P(Z < 3) = 1 - 0.99865

                                                                                            = 0.00135

 P(1.27 < X < 1.33) = 0.99865 - 0.00135 = 0.9973 .

Therefore, proportion of all bearings that falls in this acceptable range is 99.73% .

Write a function rule for the table
Ghella [55]

Answer:

D.

Step-by-step explanation:

Recall the slope is change of y over change of x which in this case the change in x is 1 while the change in y is 2 since the y's are going up by 2 while the x's are going up by 1.

So the slope is 2.

The one equation with slope 2 is D.

The answer is most likely D.

Let's check.

f(x)=2x

y=2x

y=2(-3)=-6 while x=-3.

y=2(-2)=-4 while x=-2.

y=2(-1)=-2 while x=-1.

y=2(0)=0 while x=0.

Also notice the x is doubled (multiplied by 2) to get y.
