Answer:

Step-by-step explanation:

the question says that (Patricia) is covering a table with a table cloth, the table has a diameter of 6.

Diameter is defined as the length of a straight line through the center of a circle. An example of diameter is the length of a line sliced down the center of a pie.

so the question asks how much surface is covered by the table cloth? simply it is six.

Answer:

3) 0.30

The probability a randomly selected student plays a sport given they work part time = 0.30

Step-by-step explanation:

Step(i):-

Given 'A' plays a sport

B work part time

Given P(A) = 0.48

P(B) = 0.40

P(A∩B) =0.12

P(A∪B)¹ =0.24

Step(ii):-

By using conditional probability

$P(B/A) = \frac{P(BnA}{P(A)}$

and similarly $P(A/B) = \frac{P(AnB}{P(B)}$

The probability a randomly selected student plays a sport given they work part time

Now $P(A/B) = \frac{P(AnB}{P(B)}$

$P(A/B) = \frac{0.12}{0.40}= 0.30$

Final answer:-

The probability a randomly selected student plays a sport given they work part time = 0.30

Ax - 35 + 7x - 5a

= ax - 5a + 7x - 35

= a(x - 5) + 7(x - 5)

= (a + 7) (x - 5)

Answer: (a + 7) (x - 5)
