An air force introductory course in electronics uses a personalized system of instruction whereby each student views a videotape

lys-0071 [83]

Answer:

See explaination

Step-by-step explanation:

We can define standard deviation in statistics as a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

You roll one 6sided dle, what is the probability of getting a 3, given that you know the number is odd?

katovenus [111]

Answer:

1/6

Step-by-step explanation:

Total number of outcome = 6. This is because it has 6 sides from number 1 to 6.

A) Probability of getting number 3 = 1/6 . This is because we have only one 3 in the outcome.

B) probability of getting odd number = total number of odd number ÷ total outcome .

The odd number are 1,3,5.

Therefore prob(odd) = 3/6 =1/2

The permiter of a square must be less than 160 feet. What is the maximum length of a side in feet?

ale4655 [162]

Answer:

39 ft

Step-by-step explanation:

40 feet would have been if the perimeter was 160ft. so since it has to be less than 160 the maximum (whole number) length of a side would be 39.

What is the equation of a line that passes through the point?

Artist 52 [7]

<h3>Answer: 3x-2y = 5 (choice A)</h3>

=====================================================

Explanation:

The given graph passes through (0,2) and (2,5)

The slope of this line is

m = (y2 - y1)/(x2 - x1)

m = (5-2)/(2-0)

m = 3/2

Since the y intercept is b = 2, we go from y = mx+b to y = (3/2)x+2, which is the equation of the graphed line shown.

Any parallel line will have the same slope, but a different y intercept.

-------------------

The parallel line must pass through (x,y) = (3,2). We'll use these coordinates along with m = 3/2 to find the y intercept b

y = mx+b

2 = (3/2)(3)+b

2 = 9/2+b

2-9/2 = b

4/2 - 9/2 = b

-5/2 = b

b = -5/2 ... is the new y intercept

The equation of the parallel line is y = (3/2)x-5/2, which is in slope intercept form

-------------------

Let's convert to standard form

y = (3/2)x-5/2

2y = 3x-5 .... multiply everything by the LCD 2 to clear out fractions

2y+5 = 3x

3x = 2y+5

3x-2y = 5 ... is the equation in standard form of the parallel line

-------------------

As a check, we can plug (x,y) = (3,2) into that last equation above to get

3x-2y = 5

3*3-2*2 = 5 ... replace x with 3, replace y with 2

9-4 = 5

5 = 5

Confirming that (x,y) = (3,2) is on the line.
