Conditional probability means that the action is subject to a condition, that it can only happen if some condition is met. So D is the answer. None of the others imposes any condition being met.

Answer:

Option 4 - (Probability of hitting a home run, given that you didn't strike out) is a conditional probability.

Step-by-step explanation:

Conditional probability -

The probability of event A under the condition of event B.

or, it is a measure of probability of an event given that the another event has occurred.

1) Probability of getting an A on a test  - No other event happen in this case therefore, it is not a conditional probability.

2) Probability of drawing a club from a deck of 52 cards  - No other event happen in this case therefore, it is not a conditional probability.

3) Probability of hitting a home run - No other event happen in this case therefore, it is not a conditional probability.

4) Probability of hitting a home run, given that you didn't strike out- It is a conditional probability because event (hitting a home run) is happened under the condition  that you didn't strike out.  (By definition)

Therefore, option 4 is the example of conditional probability.

At 82°F, a certain insect chirps at a rate of 61 times per minute, and at 91°F, they chirp 124 times per minute. Write an equati
Ganezh [65]

Answer:

y=7x-513

Step-by-step explanation:

Let

x----> the temperature in degrees Fahrenheit

y ---->insect chirping rate in times per minute

we have the ordered pairs

(82,61) and (91,124)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{124-61}{91-82}

m=\frac{63}{9}=7

step 2

Find the equation of the line

we know that

The equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

we have

m=7  ---> the units are chirps per minute/degree F

take the point (82,61)

substitute and solve for b

61=7(82)+b

61=574+b

b=-513

substitute

y=7x-513
