You round up or down the number. And then calculate. Anything that ends with 0,1,2,3,4 round down. Anything 5-9 round up. Example 43 + 47 would round to 40+50.

Answer:

Probability that a customer pays the bill by mail, given that the customer is female is 0.20.

Step-by-step explanation:

The complete question is:

Online By Mail Total

Male 12 8 20

Female 24 6 30

Total 36 14 50

A utility company asked 50 of its customers whether they pay their bills online or by mail. What is the probability that a customer pays the bill by mail, given that the customer is female.

Probability that a customer pays the bill by mail, given that the customer is female is given by = P(Pays bill by mail / Customer is female)

$\frac{6}{50}$ P(Pays bill by mail/Customer is female) = $\frac{P(\text{Pays bill by Mail}\bigcap \text{ Customer is Female})}{P(\text{ Customer is Female})}$

Now, Probability that customer is female = $\frac{30}{50}$

Also, Probability that customer pays bill by mail and is female = $\frac{6}{50}$

So, Required probability = $\frac{\frac{6}{50} }{\frac{30}{50} }$

= $\frac{6}{50}\times \frac{50}{30}$

= $\frac{1}{5}$ = 0.20

Hence, probability that a customer pays the bill by mail, given that the customer is female is 0.20.

Which of the following statements are true about a reflection? Select all that apply.

krok68 [10]

Answer: *An image created by a reflection will always be congruent to its pre-image.

*Corresponding angles and segments are always congruent in a reflection of a figure.

*An image and its pre-image are always the same distance from the line of reflection.

Step-by-step explanation:

Since, reflection is a rigid transformation therefore, it preserves the shape of the figure and create congruent images.

And we know that if if two figures are congruent then their corresponding angles and sides are congruent.

Reflection maps a figure to create its mirror image, and the distance of object and image is always equal from the mirror, therefore "An image and its pre-image are always the same distance from the line of reflection."
