Alejandro surveyed his classmates to determine who has ever gone surfing and who has ever gone snowboarding. Let A be the event

victus00 [196]

Answer:

{A and B are independent events}, P(A|B)=P(A)=0.16

Step-by-step explanation:

First of all we need to know when does two events become independent:

For the two events to be independent, P(A|B)=P(A) that is if condition on one does not effect the probability of other event.

Here, in our case the only option that satisfies the condition for the events to be independent is P(A|B)=P(A)=0.16.. Rest are not in accordance with the definition of independent events.

Which equations represents a line that is parallel to 3x-4y=7 and passes through the point (-4,-2)

insens350 [35]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x - 4y = 7 into this form

Subtract 3x from both sides

- 4y = - 3x + 7 ( divide all terms by - 4 )

y = $\frac{3}{4}$ x - $\frac{7}{4}$ ← in slope- intercept form

with slope = $\frac{3}{4}$

• Parallel lines have equal slopes, hence

y = $\frac{3}{4}$ x + c ← is the partial equation of the parallel line

To find c substitute (- 4, - 2) into the partial equation

- 2 = - 3 + c ⇒ c = - 2 + 3 = 1

y = $\frac{3}{4}$ x + 1 ← in slope- intercept form

Multiply all terms by 4

4y = 3x + 4 ( subtract 4 from both sides )

4y - 4 = 3x ( subtract 4y from both sides )

- 4 = 3x - 4y, that is

3x - 4y = - 4 ← in standard form

Alina by several shares of stock at $28 per-share and sells them at $24.50 per-share what is the percent of decrease in the pric

balu736 [363]

Take the absolute value of the difference, then divide it by the original amount
|28 - 24.5| / 28 = 3.5/28 = 0.125..now we multiply that by 100 to get it into a percent 0.125 * 100 = 12.5% <== ur answer

What’s the fourth question about the big wheel please help

Lapatulllka [165]

Answer: 62.83 m

<u>Step-by-step explanation:</u>

The distance of one rotation is the perimeter of the wheel <em>(which is called "circumference" since it is in the shape of a circle)</em>

Circumference (C) = 2 π · radius (r)

C = 2π (10)

= 20π

≈ 62.83
