Answer:
The diameter would be 16
Step-by-step explanation:
The area of a circle is a=
×π. Now just plug in the values you have which is you area. 201=
×π now divide by pi on both sides you that you get about 64=
. Now find the square root on both sides which will then give you 8 as your radius. To find diameter from radius you have to multiply by 2. 8*2=16
Answer:
4 possible outcomes
Step-by-step explanation:
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
Let
x------> size of the event space
y-----> size of the sample space
so
In this problem
<em>The probability of choose a blue card is
</em>
substitute
<em>The probability of choose a green card is
</em>
substitute
<em>The probability of choose a red card is
</em>
substitute
<em>The probability of choose a yellow card is
</em>
substitute
The sum of the probabilities of the 4 possible outcomes is equal to
----> represent the 100%
Answer:
The distance between them is 230.65 miles
Step-by-step explanation:
Here we use the Cosine formula

Now the distance for one hour is
= 230.65 ÷ 1
= 230.65 miles
Answer:
B. 10n-207
Step-by-step explanation:
Given,
The average number of points of 9 games = 23,
∵ Sum of observations = their average × number of observations
So, the total points for 9 games = 9 × 23 = 207,
Now, if the average of 10 games is n,
Then the total points for 10 games = 10n,
Hence, the number of points earned in 10th game = the total points for 10 games - the total points for 9 games
= 10n - 207
i.e. OPTION B is correct.
