Answer:

9/25

Step-by-step explanation:

Our box contains 10 socks. (6, which are black and 4 which are red)

Probability of picking 1 black sock will be 6/10

Number of ways it can occur / Total number of outcomes.

In this question we pick two socks, one black firstly and another black, in the second turn. When we say AND, it means intersection

P (B₁ ∩ B₂) = 6/10 . 6/10

When the events are independent, the probability of the intersection will be the product of the probabilities,

P (B₁ ∩ B₂) = 36/100 = 9/25

Find the area of this figure.
ryzh [129]

Answer:

1824 square inches

Step-by-step explanation:

First, separate the figure into two sections. The triangle on top, and the rectangle on the bottom.

to get the area of the triangle, simply multiply height times width and divide by two.

48 x 12 = 576

576/2 = 288

the area of the triangle is 288 sq in

next, multiply the height and width of the rectangle to get its area.

32 x 48 = 1536

add 1536 to 288 to get the area of the complete figure

1536 + 288 = 1824

the answer is 1824 square inches

Solve for a.<br><br> 5a - 2 = 23<br> a = ?
snow_tiger [21]
5a - 2 = 23.

First, take 5a - 2 = 23 and add 2 to each side

5a - 2 = 23
     +2    +2
5a = 25

now, divide each side by 5

5a = 25
/5      /5

a = 5

RoseWind [281]

Answer: 84.09%


Step-by-step explanation:

1. 220-30=? ?=185

2. Divide 185 by 220 (as a fraction, 185 out of 220 is 185/220 which also means divide) 185 divided by 220 is about 0.8409

3. Multiply 0.8409 by 100 (since there is two zeros in 100 we can move the decimal to the right twice which gets you 84.09
