3 0

Answer:

The equation of line is y+2=0

Step-by-step explanation:

The equation of line passing through the point $(x_{1},y_{1} )$ and having slope m is

$y-y_{1} = m (x-x_{1}$

Given slope m=0 and given point is is (-2,-2)

$y-(-2)=0(x-(-2))$

$y+2=0$

therefore equation of the straight line is $y+2=0$

Therefore the straight is parallel to negative x-axis(y=-2)

Write the given rate as a fraction in simplest form. 12 cups for every 39 people O 39/12 cups per person O 13/4 cups per person

Nata [24]

Answer:

4/13 cups per person

Step - by - step explanation:

Write the given rate as a fraction in simplest form. 12 cups for every 39 people

O 39/12 cups per person

O 13/4 cups per person

0 4/13 cups per person

O 12/39 cups per person

There are 39 people

12 cups are available

Determine the number of cups per person

Cups per person = 12 cups / 39 people

= 12/39 cups per person

Divide both numerator and denominator by 3

= 4/13 cups per person

Cups per person as a fraction in simplest form = 4/13 cups per person

The diameters of bolts produced in a machine shop are normally distributed with a mean of 5.71 millimeters and a standard deviat

Harlamova29_29 [7]

Answer:

The bolts with diameter less than 5.57 millimeters and with diameter greater than 5.85 millimeters should be rejected.

Step-by-step explanation:

We have been given that the diameters of bolts produced in a machine shop are normally distributed with a mean of 5.71 millimeters and a standard deviation of 0.08 millimeters.

Let us find the sample score that corresponds to z-score of bottom 4%.

From normal distribution table we got z-score corresponding to bottom 4% is -1.75 and z-score corresponding to top 4% or data above 96% is 1.75.

Upon substituting these values in z-score formula we will get our sample scores (x) as:

$z=\frac{x-\mu}{\sigma}$

$-1.75=\frac{x-5.71}{0.08}$

$-1.75*0.08=x-5.71$

$-0.14=x-5.71$

$-0.14+5.71=x-5.71+5.71$

$5.57=x$

Therefore, the bolts with diameters less than 5.57 millimeters should be rejected.

Now let us find sample score corresponding to z-score of 1.75 as upper limit.

$1.75=\frac{x-5.71}{0.08}$

$1.75*0.08=x-5.71$

$0.14=x-5.71$

$0.14+5.71=x-5.71+5.71$

$5.85=x$

Therefore, the bolts with diameters greater than 5.85 millimeters should be rejected.
