Answer:

Probability = 2/13 ≈ 15.4%

Step-by-step explanation:

We are looking for probability of drawing an ace or king from a standard deck of cards.

In a standard deck of cards, there are 4 ace and 4 king.

4 + 4 = 8, this is the number of possible "correct" cards you can draw, which satisfy the conditions.

Since a standard deck has 52 cards, this is the number of cards you can draw, the "possible outcomes".

Probability is the number of "correct" outcomes divided by the total possible outcomes.

The probability is 8 / 52, but we need to reduce the fraction.

Both numerator and denominator are divisible by 4.

8 / 52 = 2 / 13

If you want the probability as a percentage, divide 2 by 13 and multiply by 100.

Probability = 2/13 ≈ 15.4%

Which is an equation in point-slope form for the line that passes through the points (−1,4) and (3,−4) ? y+4=2(x−3) y+4=−2(x−3)

beks73 [17]

Answer:

y-4=-2(x+1)

Step-by-step explanation:

y-y1=m(x-x1)

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

m=(-4-4)/(3-(-1))

m=-8/(3+1)

m=-8/4

m=-2

y-4=-2(x-(-1))

y-4=-2(x+1)

What are the width and the area of the rug?

kaheart [24]

Given:

The rug is in the shape of a kite.

$d_1=31$ in

$d_2=9$ in

To find:

The width and area of the rug

Solution:

Width of the rug = 9 in

Area of the kite = $\frac{1}{2} \times d_1 \times d_2$

$$=\frac{1}{2} \times 31 \times 9$

= 139.5 in³

The area of the rug is 139.5 in³.

Colin pays £766.45 a year on his car insurance.

aliina [53]

Answer:

£807.84

Step-by-step explanation:

Cost of Collins car insurance per year = £766.45

Percentage increase in price = 5.4%

How much does the insurance cost now?

Cost of the insurance now = £766.45 + 5.4% of £766.45

= 766.45 + 5.4/100(766.45)

= 766.45 + 0.054(766.45)

= 766.45 + 41.3883

= 807.8383

Cost of the insurance now = £807.84
