Answer:

0.74

Step-by-step explanation:

A <u>tree diagram</u> is a visual way of showing combinations of <u>two or more events</u>. The outcome of each branch is labelled at the end of the branch line and its probability is written alongside the branch.

To calculate the probabilities of each combination, follow the branches and <u>multiply the probabilities</u> together.

There are two possible combinations to get a final outcome of D:

  • A and D = 0.6 × 0.7 = 0.42
  • B and D = 0.4 × 0.8 = 0.32

Therefore, the probability of D is:

⇒ P(D) = P(A and D) <u>OR</u> P(B and D):

⇒ P(D) = 0.42 + 0.32

⇒ P(D) = 0.74

Kite WXYZ is graphed on a coordinate plane. What is the area of the kite? 7 square units 8 square units 14 square units 16 squar
Ghella [55]
The area of the kite can be found as follows;
Area=[area of XWY]+[areaYWZ]
area XWY=1/2*b*h
=1/2*4*3=6 sq units

area YWZ=1/2*b*h
=1/2*4*4=8 sq units

Hence the area of the kite will be:
Area=6+8=14 sq. units

The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is
Viktor [21]

Answer:

There are approximately 171 families in the sample.

Step-by-step explanation:

Percentile meaning:

When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.

Twenty-four of the families in the sample turned on the television for 23 hours or less for the week. The 14th percentile of the data is 23 hours.

This means that 24 is 14% of the total number of families.

Approximately how many families are in the sample?

Using a rule of three.

24 - 0.14

x - 1

0.14x = 24

x = 24/0.14

x = 171.4

Rounding to the nearest integer

There are approximately 171 families in the sample.

Answer:

y = 30

x = 60

Step-by-step explanation:

4y and 2y are consecutive angles, which means they are equal to 180° when added together

that is the same with x and (5x - 180)

to solve, you set the equations to 180

solving:

4y + 2y = 180

6y = 180

y = 30

x + 5x - 180 = 180

6x = 360

x = 60
