Which absolute value statement describes 9 degrees below zero?
a) |-9| = 9
b) -|9| = -9
c) -|-9| = 9
d) |-9| = -9

Option C is correct.  

Step-by-step explanation:

Given : A statement .

To find : Which absolute value statement describes 9 degrees below zero.

Solution : We know that  the values Inside the modulus is always positive whether it is negative or positive .

We need to find 9 degrees below zero.

⇒ - | -9 | = 9.

⇒ - 9 =9

Therefore , Option C is correct.  

The correct option is option [B].

The probability that both girls Selena and Tracey will a next at bat is .

Step-by-step explanation:

Independent events:

If A and B are event. The occurrence of one of them does not affect the outcomes of other event. Then A and B are independent events.

P(A and B) =P(A)× P(B)

Dependent events:

If A and B are event. The outcomes of one of them affects the outcomes of other event. Then A and B are called dependent events.

P(A and B) =P(A)× P(B|A)= P(B)×P(A|B)

Given that,

Selena has 8 hits out of 20 times at bat.

The number of hits by Tracey out of 16 is 6 at bat.

A= Selena hits a softball.

B= Tracey hits a softball.

The probability that the Selena his a softball is

=P(A)

The probability that the Tracey his a softball is

=P(B)

Both event are independent. Sine the events do not affect the outcomes of other event.

The probability that both girls will a next at bat is

=P(A and B)

=P(A)×P(B)
