A circle has a diameter of 62.8 cm. What is the length of this circle's radius?
Pls give me an actual answer

Answer:

B) 0.283

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

25% of the students drive themselves to school.

This means that [tex]p = 0.25[/tex]

Class of 18 students

This means that [tex]n = 18[/tex]

What would be the probability that at least 6 students drive themselves to school?

This is

[tex]P(X \geq 6) = 1 - P(X < 6)[/tex]

In which

[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]

So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{15,0}.(0.25)^{0}.(0.75)^{18} = 0.006[/tex]

[tex]P(X = 1) = C_{15,1}.(0.25)^{1}.(0.75)^{17} = 0.034[/tex]

[tex]P(X = 2) = C_{15,2}.(0.25)^{2}.(0.75)^{16} = 0.096[/tex]

[tex]P(X = 3) = C_{15,3}.(0.25)^{3}.(0.75)^{15} = 0.17[/tex]

[tex]P(X = 4) = C_{15,4}.(0.25)^{4}.(0.75)^{14} = 0.213[/tex]

[tex]P(X = 5) = C_{15,5}.(0.25)^{5}.(0.75)^{13} = 0.199[/tex]

[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.006 + 0.034 + 0.096 + 0.17 + 0.213 + 0.199 = 0.718[/tex]

[tex]P(X \geq 6) = 1 - P(X < 6) = 1 - 0.718 = 0.282[/tex]

Closest option is B, just a small rounding difference.

Answer:

62.9 lbs

Step-by-step explanation:

20 34

37 x

20x = 1258

x = 62.9

Answer:

[tex]\boxed {\boxed {\sf 62.9 \ pounds}}[/tex]

Step-by-step explanation:

Let's create a proportion using this setup:

[tex]\frac{books}{weight}=\frac{books}{weight}[/tex]

We know that 20 books weight 37 pounds. We don't what 34 books weigh, so the weight is x pounds.

[tex]\frac{20 \ books}{37 \ pounds}=\frac{34 \ books}{x \ pounds}[/tex]

[tex]\frac{20}{37}=\frac{34}{x}[/tex]

Cross multiply. Multiply the first numerator by the second denominator. Then, the first denominator and second numerator.

[tex]20*x=37*34\\20x=1258[/tex]

Since we are solving for x, we have to isolate the variable. It is being multiplied and the inverse of multiplication is division. Divide both sides by 20.

[tex]20x/20=1258/20 \\x= 1258/20 \\x=62.9[/tex]

34 books weigh 62.9 pounds.

Answer:

Your answer would be 4

Step-by-step explanation:

Convert the 4 3/4 into a decimal, 4.75.

First, you must multiply 5 and -3.5 together. Then you add everything on top together.

Divide the fraction

Answer:

F. 4

Explanation:

(5(-3.5)+4(3/4)-3.25) / -4 = 4

Answer:

one solution

⇒ The system of linear equation represented on the graph has only one solution.

Given :

In triangle AOR and triangle KTE :

Since two sides and one included angle of these two triangles are equal, we can conclude that these triangles are congruent under the SAS congruence criterion.

Answer:

Aw don't cry <3

It would be easier if you use a website with a graph! There is a website called "desmos" and if you search up desmos graphing calculator you will find it. Type in the points in the website, and it would add in the points for you.

but here is a piece of key information:

Make [tex]\frac{3}{4}[/tex] into a decimal. That would be 0.75.

Since it says "of the way from", count the boxes in the graph from each point.

Hope this helps! ^.^

Answer: 22% fencing

Step-by-step explanation:

Mr. Fuller needs 260 feet of fencing to put around his rectangular yard.

Perimeter is the measure of the figure on its circumference.

Here,
To find the perimeter of the rectangular yard, we need to add up the lengths of all four sides.

The two sides that are 55 feet long are the width of the yard, and the two sides that are 75 feet long are the length of the yard.

So, the perimeter of the yard is:

Perimeter = 2 × (length + width)

Perimeter = 2 × (75 feet + 55 feet)

Perimeter = 2 × 130 feet

Perimeter = 260 feet

Therefore, Mr. Fuller needs 260 feet of fencing to put around his rectangular yard.

Answer:

20.8

Step-by-step explanation:

so x is opposite the 60 degree angle so that means that it is half of the hypotanuese times root three

so then x would be equal

24/12=12 root three which is equal to 20.8

Answer:

[tex]a_4 = -108[/tex]

Step-by-step explanation:

Given

[tex]a_n = -3a_{n-1}[/tex]

[tex]a_1 = 4[/tex]

Required

Find [tex]a_4[/tex]

[tex]a_4 = -3a_{4-1}[/tex]

[tex]a_4 = -3a_3[/tex]

We calculate for a3

[tex]a_3 = -3a_{3-1}[/tex]

[tex]a_3 = -3a_2[/tex]

Calculate for a2

[tex]a_2 = -3a_{2-1[/tex]

[tex]a_2 = -3a_1[/tex]

Substitute 4 for a1

[tex]a_2 = -3*4[/tex]

[tex]a_2 = -12[/tex]

Substitute -12 for a2 in [tex]a_3 = -3a_2[/tex]

[tex]a_3 = -3 * -12[/tex]

[tex]a_3 = 36[/tex]

Substitute 36 for a3 in [tex]a_4 = -3a_3[/tex]

[tex]a_4 = -3*36[/tex]

[tex]a_4 = -108[/tex]
