Evaluate: C(14, 10)
no pic just answer it

Answers

Given:

The combination C(14,10).

To find:

The value of the given combination.

Solution:

We know that,

[tex]C(n,r)=\dfrac{n!}{r!(n-r)!}[/tex]

Using this formula, we get

[tex]C(14,10)=\dfrac{14!}{10!(14-10)!}[/tex]

[tex]C(14,10)=\dfrac{14\times 13\times 12\times 11\times 10!}{10!(4)!}[/tex]

[tex]C(14,10)=\dfrac{14\times 13\times 12\times 11}{4\times 3\times 2\times 1}[/tex]

[tex]C(14,10)=7\times 13\times 11[/tex]

[tex]C(14,10)=1001[/tex]

Therefore, the value of C(14,10) is 1001 and the correct option is B.

The equivalent expression of "[tex]C(14,10)[/tex]" is "1001".

Equivalent expression:

using formula:

[tex]\to ^n C_r=\frac{n!}{r!(n-r)!}[/tex]

putting the given value into the above formula:

[tex]\to ^{14} C_{10}=\frac{14!}{10!(14-10)!}[/tex]

              [tex]=\frac{14 \times 13 \times 12 \times 11 \times 10! }{10! \times 4 \times 3 \times 2 \times 1}\\\\=\frac{14 \times 13 \times 12 \times 11 }{ 4 \times 3 \times 2 \times 1}\\\\={7 \times 13 \times 11 }{}\\\\=1001[/tex]

Therefore, the final answer is "1001".

Dimension of rectangule 1 :

10 inches * 13 1/2 inches

Area = (10 * 27/2) inch² = 135 in²

Dimension of rectangle 2 :

10 1/3 inch * 10 1/2 inch

Area = (31/3 * 21/2) in² = 108.5 in²

Tot square inch of construction paper needed /

C. 222°
D. 276°

Answers

9514 1404 393

Answer:

  138°

Step-by-step explanation:

The measure of arc ABC is the measure of the corresponding central angle, ∠ANC. That angle is shown as 138°, so the measure of arc ABC is 138°.

Measure of an angle  ABC is 111 degrees i.e. [tex]m[/tex]∠ABC = 111 degrees.

Angle subtended by an Arc of a circle-Theorem

The angle subtended by an arc at the center of the circle is double the angle subtended by the same arc at the circumference of the circle.

According to the given question

The angle subtended at the center of circle, i.e. ∠ANC = 138 degrees.

The exterior angle at the center is (360 - 138)degrees = 222 degrees

by angle subtended by an Arc of a circle theorem

[tex]m[/tex]∠ABC = [tex]\frac{222}{2}[/tex] [tex]= 111 degrees[/tex]

Hence, [tex]m[/tex]∠ABC = 111 degrees.

A test is divided into 4 sets of problems with the same number of problems in each set. Alice correctly solves 35 problems. How many problems are on the test if Alice solved more than 60 percent of the problems, but less that 65 percent of all problems? Give all possible answers.

Answers

Answer:

56 problems

Step-by-step explanation:

The number is between

35/0.6 = 58.33

and

35/0.65 = 53.84

and

is multiple of 4

Possible numbers are:

54, 55, 56, 57 and 58

Only one of the numbers, 56 is divisible by 4

Answer:

The possible number of question are

232,228,224, and 220.

Step-by-step explanation:

Given that Alice correctly solves 35 problems

From the statement, 35 represents between 60 and 65 percent of the whole problem.

Let x be the total number of questions and choose 61% as the percentage Alice solved then,

61% of x = 35

0.61x = 35

x = 35/0.61

= 57.37

Aproximately 57

The possible answer are 58, 57, 56, 55

Since this represent 1 part, the question on test are:

54 * 4 = 232

or

57 * 4 = 228

or

56 * 4 = 224

or

55 * 4 = 220

What is the length of red segment EC to the nearest tenth?

Answers

First you find the length of the green rectangle by using a^2 + b^2 = c^2
So that means 4^2 + 7^2 = length of green
That equals 8.1 when you square root it.
Then, you use 8.1^2 + 3^2 (which is the green rectangle height) to find the red line using the same equation
So your answer is 8.6 cm.

The Acme Company produces metal rods. The largest rod that the Acme company produces is 10 feet long and 2 feet in diameter. How much material (the volume) is required to produce 1 metal rod? Round to the nearest tenth. Use 3.14 for \piπ .

Answers

Answer:

31.4 ft³

Step-by-step explanation:

Using the relation :

Volume, V = πr²h

Height = 10 feets ; diameter = 2 feets, radius, r = 2 /2 = 1 feet

Volume , V = π * 1^2 * 10

V = 1 * 10 * 3.14

V =31.4 feet³

Hence, the volume of material needed to produce 1 metal rod is 31.4 ft³
