B. 314cm2
A. 62.8cm2A circle has a radius that measures 10 centimeters. What is the area of the circle to the nearest tenth? Use 3.14 for pi.
Group of answer choices
B. 314cm2
A. 62.8cm2
Radius(R)=10cm
We know,
Area of circle(A)=πr^2
=3.14×10^2
=3.14×100
=314cm^2
Answer:
$3.33
Step-by-step explanation:
The costs listed are the cost for the total dinner (all 10 people). You need to add up all the costs, then divide by 10 to find the cost per person.
12.50 + 2.29 + 1.89 + 2.47 + 1.29 + 1.65 + 2.25 + 8.98 = 33.32
33.32 / 10 = 3.332
Rounded to the nearest cent, each serving costs $3.33.
Answer:
Hello there, you would multiply.
Step-by-step explanation:
You can't add by 10 if there are 10 more people, because all the ingredients would have to be timed

Chicken A: Standard deviation of A is 4.6 grams; 68% of the eggs fall between 50.9 grams and 60.1 grams.
Chicken B: Standard deviation of B is 4.9 grams; 68% of the eggs fall between 51.9 grams and 61.7 grams.
The difference between the mean weight of Chicken B’s eggs and the mean weight of Chicken A’s eggs to the nearest tenth is...?
The difference between the meanweight of Chicken B's eggs and the mean weight of Chicken A's eggs to the nearest tenth is 1.8 grams.
A normaldistribution is a probability distribution that is symmetric around the mean, with most of the data points falling close to the mean and fewer data points falling farther away from it.
The shape of a normal distribution is often referred to as a bellcurve because when the distribution is graphed, the resulting curve resembles a bell
We have,
Since both datasets follow a normaldistribution, we can use the empirical rule (also known as the 68-95-99.7 rule) to find the mean weight of each chicken's eggs.
For Chicken A, we know that 68% of the eggs fall between 50.9 grams and 60.1 grams. This means that the mean weight of Chicken A's eggs is the average of these two values:
Mean of A = (50.9 + 60.1) / 2 = 55.0 grams
For Chicken B, we know that 68% of the eggs fall between 51.9 grams and 61.7 grams. This means that the mean weight of Chicken B's eggs is the average of these two values:
Mean of B = (51.9 + 61.7) / 2 = 56.8 grams
The difference between the meanweight of Chicken B's eggs and the mean weight of Chicken A's eggs is:
Difference = Mean of B - Mean of A
= 56.8 - 55.0
= 1.8 grams
Therefore,
The difference between the meanweight of Chicken B's eggs and the mean weight of Chicken A's eggs to the nearest tenth is 1.8 grams.

Find the probability that she develops lung cancer, given
she smokes.
To find the probability that she develops lung cancer given that she smokes, multiply the two probabilities together:
4/9 x 3/10 = (4 * 3) / (9*10) = 12/90 = 2/15
