Whats the area of a circle with a circumference of \blueD{50.24}50.24start color #11accd, 50, point, 24, end color #11accd units.
Answer:
[tex]A=200.96\ unit^2[/tex]
Step-by-step explanation:
Given that,
The circumference of the circle, C = 50.24 units
We need to find the area of the circle.
The formula for the circumference of the circle is given by :
[tex]C=2\pi r[/tex]
r is the radius of the circle
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{50.24}{2\times 3.14}\\\\r=8\ units[/tex]
The formula for the area of a circle is given by :
[tex]A=\pi r^2\\\\A=3.14\times 8^2\\A=200.96\ unit^2[/tex]
So, the area of the circle is equal to [tex]200.96\ unit^2[/tex].

A bag contains 30 ping-pong balls, each with a different number written on it from 1 to 30. What is the probability of selecting a ball with a number that is less than 13?
Answer:
...
Step-by-step explanation:
Answer:
so you have a 40% chance or 2/5 chance
Step-by-step explanation:
30 numbers in total
12 are less than 13
so you have a 12/30
simplify
2/5 = 0.4 or 40%
Can u help solve this step by step?
Answer:
[tex]\sqrt{28}[/tex]
Step-by-step explanation:
It is given that the triangle (QRS) is right, thus one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states,
[tex](a)^2+(b)^2=(c)^2[/tex]
Where (a) and (b) are the legs or the sides adjacent to the right angle and (c) is the hypotenuse or the side opposite the right angle. The unknown side in the triangle is a leg, thus, let (b) represent this value. Substitute in the given values and solve,
[tex](6)^2+(b)^2=(8)^2\\\\36+b^2=64\\\\b^2=28\\\\b=\sqrt{28}[/tex]
which box plot matches the data set
21,22,23,26,29,32,34,38,40,42,43
For this data set,the first quartile is 23 the median is 32 the 3rd quarter is 40
Answer:
Option C is your answer
Step-by-step explanation:
21,22, 23, 26,29, 32, 34,38, 40, 42,43
Yes, Q1 is 23, median is 32, Q3 is 40
So the box should start on 23, end on 40, and have its inner line over 32.
In your picture, that's option C
Answer:its c

When identifying properties of n - sided polygons where 3 _< n <_ 10. What does 3 <_ n <_ 10 means ?
9514 1404 393
Answer:
3 ≤ n ≤ 10 means "three is less than or equal to n, which is less than or equal to 10"
you're concerned with polygons having 3 to 10 sides, inclusive.
Step-by-step explanation:
The symbol ≤ means "less than or equal to." The compound inequality ...
3 ≤ n ≤ 10
means the value of n may range from 3 to 10, inclusive.
__
In the present context, where n is a number of sides, it means you're concerned with polygons that are any of ...
triangle, quadrilateral, pentagon, hexagon, ...
heptagon, octagon, nonagon, decagon

What is the Alternate Hypothesis for the following situation:
At most 60% of American vote in the presidential elections.
Answer:
The alternative hypothesis is; Hₐ;
[tex]\hat p[/tex] > 60%
Step-by-step explanation:
The given hypothesis of the number of Americans that vote in the presidential election is;
Hypothesis; At most 60% of Americans vote in the presidential elections
Therefore, the hypothesis states that the percentage of Americans that vote in the presidential ≤ 60%
The given hypothesis is the null hypothesis due to the presence of one of the operators ≤, ≥, or =
The null hypothesis is therefore, H₀: [tex]\hat p[/tex] ≤ 60%
Therefore, the alternative hypothesis is; Hₐ; [tex]\hat p[/tex] > 60%.

Answer:
8.38
Step-by-step explanation:
The underlined number is in the hundredths place, so that means that we're going to round there. That means that you look at the number to its right and if it's lower than 5, it stays the same. However, if it's 5 or higher, you round it up. For example, if the number was 8.386, we would round it to 8.39.

Two numbers have a sum of - 6 and a product of 9.
Use the quadratic equation n^2 - 6n + 9 = 0 to determine the two numbers.
n2 - 6n + 9 = 0
Answer:
3, 3
Step-by-step explanation:
[tex]n^2 - 6n + 9 = 0 \\ n^2 - 3n - 3n+ 9 = 0 \\ n(n - 3) - 3(n - 3) = 0 \\ (n - 3)(n - 3) = 0 \\ n - 3 = 0, \: \: n - 3 = 0 \\ n = 3, \: \: n = 3[/tex]
Thus, the two numbers are 3, 3

Write the equation Y=mx+b Not just the rate of change
Answer:
y=2/5x+8/5
Step-by-step explanation:
so say you plot a graph of rain against the hours the gradient would be the rate of change and the information given as your points and the gradient
now to get an equation of a straight line use one of your points eg(1,2) and the gradient or rate of change mine was 0.4
