Evaluate 10C4. Type a numerical answer in the space provided. Do not type spaces in your answer.

1 answer:

4 0

10C4 represent the Combinations of 10 objects taken 4 at a time.

The formula for nCr is:

$nCr= \frac{n!}{r!(n-r)!}$

In the given case, n=10 and r=4. Using these values we get:

$10C4= \frac{10!}{4!(10-4)!} \\ \\ 
= \frac{10!}{4!*6!} \\ \\ 
=210$

This means we can make 210 combinations of 10 objects taken 4 at a time.

Which equation results from adding the equations in this system?

eimsori [14]

Answer: 3x=3

Step-by-step explanation: Let's divide this into parts--

1. Adding the x variables: -2x+5x or 5x-2x = 3x.

2. Adding the y variables: y-y or -y+y = 0. (The negative and the positive y cancel each other out.)

3. Adding the numbers: 8-5 or -5+8 = 3.

Now just put it back into an equation: 3x + 0 = 3.

We don't need to add the 0, so the equation changes into 3x = 3.

Jaime makes the following claim.

Sphinxa [80]

Jaime is incorrect, the angle does not depend on the radius of the circles.

<h3>Is Jaime correct?</h3>

Remember that an angle that defines an arc on a circle, does not depend on the radius of the circle.

So, if we have an angle with a measure of π/3 radians in a circle with a radius of 3 inches and an angle with a measure of π/3 radians in a circle with a radius of 6 inches, these two angles are exactly the same thing.

The radius of the circle only has an impact on the length of the arc defined by the angle.

So Jaime is clearly incorrect.

The sun shines at a 30° angle to the ground. To the nearest inch, how long is the shadow cast by a 72-in. tall fence post?

tensa zangetsu [6.8K]

The length of the shadow is 124.7 in

<u>Explanation:</u>

<u />

Given:

Angle, θ = 30°

Height of the fence, h = 72 in

Length of the shadow, l = ?

Given:

tan 30° = $\frac{perpendicular}{base} = \frac{height of the fence}{length of the shadow}$

$\frac{1}{\sqrt{3} } = \frac{72}{l} \\\\l = 72\sqrt{3} \\\\l = 124.7 in$

Therefore, the length of the shadow is 124.7 in

The measure of dispersion that measures how much the data differ from the mean is called the.

Alenkinab [10]

The measure of dispersion that measures how much the data differ from the mean is called the standard deviation.

<h3>What is standard deviation?</h3>

Standard deviation is a statistical measure of dispersion as opposed to the measure of central tendency like mean, median and mode.

The standard deviation is a measure of how spread out data values are around the mean.

It is defined as the square root of the variance and represented with the Greek letter σ.
