Answer:

y = x + 5

1 would be the slope AKA m

Step-by-step explanation:

y = mx + b

mx is change of y to the change in x.

m is the slope

As you can see in the problem above, everytime y moves up 1, x moves to the right 1.

b is the y intercept - where is y when x is at 0?

This will help you find the slope of future problems hopefully. :)

Answer:

Step-by-step explanation:

$\frac{rise}{run}=slope$

$\frac{1}{1} =1$

therefore the slope is 1

What is 6/10 rounded to the nearest half

belka [17]

6/10 rounding to the nearest half would be 1, not 0.

Reason for this: Here is a number line to help you!

|----|----|

Left line = 0

Middle line = 1/2

Right line = 1

Here is another rule!

0/10, 1/10, 2/10, 3/10, 4/10 = rounded to the nearest half would be 0

5/10, 6/10, 7/10, 8/10, 9/10, 10/10 = rounded to the nearest half would be 1.

So 6/10 rounded to the nearest half is 1.

Hope this helped!

Suppose the equation for line A is given by 2x = 5y – 25. If line A and B are perpendicular

Ludmilka [50]

The required equation of line B is 2y+5x=-2

The equation of a line in point-slope form is expressed as:

y-y0 = m(x-x0)

m is the slope of the line

(x0, y0) is the point on the line

Given the line A expressed as:

2x = 5y – 25

Rewrite in standard form

5y = 2x + 25

y = 2/5 x + 5

The slope will be 2/5

The slope of the perpendicular line will be;

$M = \frac{-1}{(2/5)}\\M = \frac{-5}{2}$

Substitute the point (-6, 14) and slope -5/2 into the equation above to get the required equation of line B

$y-14=-5/2(x+6)\\2(y-14) = -5(x+6)\\2y-28=-5x-30\\2y+5x=-30+28\\2y+5x=-2\\$

Hence the required equation of line B is 2y+5x=-2

PREVIOUS ANSWERS MY NOTES Calls to a customer service center last on average 2.8 minutes with a standard deviation of 1.4 minute

rjkz [21]

Answer:

The expected total amount of time in minutes the operator will spend on the calls each day is of 210 minutes.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

n-values of a normal variable:

For the sum of a sample of n values, the mean is of $M = n\mu$ and the standard deviation is of $s = \sigma\sqrt{n}$

Average 2.8 minutes

This means that $\mu = 2.8$

75 calls each day.

This means that $n = 75$

What is the expected total amount of time in minutes the operator will spend on the calls each day?

$M = n\mu = 75(2.8) = 210$

The expected total amount of time in minutes the operator will spend on the calls each day is of 210 minutes.

The driver of a car traveling at a speed of 40 miles per hour had to stop the car quickly. If the driver`s reaction time was 34

natulia [17]

Answer:

The car travel 44 feet during the driver`s reaction time.

Step-by-step explanation:

The sentence "If the driver`s reaction time was 34 of a second" has to be changed as "If the driver`s reaction time was 3/4 of a second"

If the driver drives at a speed of 40 miles per hour, it means s/he travels

40 × 5280 = 211200 feet per hour.

1 hour is 60 minutes and 1 minute is 60 seconds.

That is, 1 hour is 3600 seconds.

Therefore the driver travels $\frac{211200}{3600}$ feet in a second.

And since the reaction time is $\frac{3}{4} =0.75$ of a second, the car travels $\frac{211200}{3600 } * \frac{3}{4}=44$ feet during the reaction time.
