10. When events are independent, the joint probability is the product of the individual probabilities.

... p(senior & female) = p(senior) × p(female) = 0.30 × 0.54 = 0.162 = 16.2%

11. When events are mutually exclusive, the probability of one or another is the sum of the individual probabilities.

... p(soph or frosh) = p(soph) + p(frosh) = 0.28 + 0.26 = 0.54 = 54%

Tickets for the school play sell for S4 each. Which graph shows the relationship between the number of tickets sold
Fiesta28 [93]

Answer:

Step-by-step explanation:

Tickets for the school play sell for $4 each.

Number of tickers sold = x

Total income from the tickets = y

This means when x = 1, y = 4

SO when we sell 1 ticket (x = 1),  we make $4 income (y = 4).

If we sell 2 tickets (x = 2), we will make $8 income (y = 8)

If we sell 3 tickets ( x = 3) , we will make $12 income (y = 12)

If we sell 4 tickets ( x = 4), we will make $16 income ( y =  16) etc.

Also note that when we sell 0 tickets (x = 0), we make no income (y = 0).

So if you create a graph, it should look something like this:

A light bulb filament is one-hundredth of an inch thick, with an allowable error of 2 percent. What is the least allowable thick
Andreyy89

Answer:

0.00998 Inches

Step-by-step explanation:

Thickness of the light bulb filament = 0.01 Inch

Allowable error = 2%.

2% of 0.01 = 0.02 X 0.01 =0.0002 Inch

Therefore, the allowable thickness of the bulb filament

=0.01 \pm 0.0002 $ Inches

We can then calculate the least allowable thickness of the filament as:

=0.01 - 0.0002 \\=0.00998$ Inches

The least allowable thickness of the filament is 0.00998 Inches.
