Option (A) This is an example of a dependent event because she draws a name and does not place it back into the hat is the correct answer.
What is dependent event?A dependent event is affected by the outcome of a second event. When two events are dependent events, one event influences the probability of another event.
What is independent event?Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event.
For the given question,
Barbara is trying to decide which of her two friends to invite over Saturday night for a sleepover.
Barbara will draw one name and then draw another name.
There are totally six names in the hat, Barbara draws one name without replacing it she draws the second name.
So the probability of second event depends on the first event.
Hence we can conclude that option (A) This is an example of a dependent event because she draws a name and does not place it back into the hat is the correct answer.

Answer:
Radius=10
Diameter=20
circumference=62.8
Area=314
Answer:
Radius: 10 inches
Diameter: 20 inches
Circumference: 62.8 inches
Area: 314 inches squared
Step-by-step explanation:
Radius:
They have already given you the radius (10), so no formula is needed.
Diameter:
To find the diameter, multiply the radius by 2, so:
2 × 10 = 20
Circumference:
To find the circumference, use this formula:
C=2πr
2 × π (3.14) = 6.28
6.28 * 10 = 62.8
Area:
To find the area, use this formula:
A=πr²
π (3.14) × 100 = 314

19. When baking a cake, you have a choice of the following pans:
1. a round cake pan that is 2 inches deep and has a 7-inch diameter
2. a 6 inch × 9-inch rectangular cake pan that is 2 inches deep
Which of these pans has the larger volume? Justify your answer.
Note: Write an essay-like answer, and I will give brainliest and rating.
The answer is
round cake - 82.42 in²
rectangular cake - 114 in²
Round cake:
d = 7 in
r = d/2 = 7 in / 2 = 3.5 in
h = 2 in
The surface are of a cylinder is:
A = 2πr² + 2πrh
The surface are of the round cake (which is actually a cylindrical cake) excluding the bottom is:
A = 2πr² + 2πrh - πr²
A = πr² + 2πrh
A = 3.14 * 3.5² + 2 * 3.14 * 3.5 * 2
= 38.46 + 43.96
= 82.42 in²
Rectangular cake:
w = 6 in
l = 9 in
h = 2 in
The surface are of a rectangle is:
A = 2wl + 2wh + 2lh
The surface are of the rectangular cake excluding the bottom is:
A = 2wl + 2wh + 2lh - wl
A = wl + 2wh + 2lh
A = 6 * 9 + 2 * 6 * 2 + 2 * 9 * 2
= 54 + 24 + 36
= 114 in²

What is the slope of the figure below? Write your answer as a rational number.
Answer:
2/3
Step-by-step explanation:
Slope = the rise over run! So if you calculate (or just count) the rise and run between point (-3,6) and (0,4), it is 2 over 3, which cannot be further simplified so it is just the fraction 2/3.

A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number can be repeated. You can choose from among four letters, A, B, C, and D, and two numbers, 5 and 6.
The size of the sample space is ___
If a code is chosen at random, the probability that it has a letter that immediately follows an odd number is ___
If a code is chosen at random, the probability that D is in the code but is not in the first position is ___
ANSWER ALL 3
The probability that it has a letter that immediately follows an odd number 1/2. The probability that D is in the code but is not in the first position 1/4.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
