The ratio of boys to girls is 5 to 9. If there are 120 more girls than boys, how many boys are there? Can you please show work o

poizon [28]

5*30 = 150
9*30 = 270
Since the ratio is 5:9 you have to multiply both numbers in the ratio by the same constant.
I just started multiplying by 10, then 20, then 30 until I got numbers that had a difference of 120.
There are 150 boys.
Setting up an equation
5x + 120 = 9x
Solve for x and then multiply the ratio by the x to get the same result.

How many 10-digit ternary strings are there that contain exactly two 0s, three 1s, and five 2s?

Svet_ta [14]

There are $\dbinom{10}2$ ways of picking 2 of the 10 available positions for a 0. 8 positions remain.

There are $\dbinom83$ ways of picking 3 of the 8 available positions for a 1. 5 positions remain, but we're filling all of them with 2s, and there's $\dbinom55=1$ way of doing that.

So we have

$\dbinom{10}2\dbinom83\dbinom55=\dfrac{10!}{2!(10-2)!}\dfrac{8!}{3!(8-3)!}\dfrac{5!}{5!(5-5)!}=2520$

The last expression has a more compact form in terms of the so-called multinomial coefficient,

$\dbinom{10}{2,3,5}=\dfrac{10!}{2!3!5!}=2520$

What is the area of a sector of a circle with of 5 meters and subtended by a central angle of 180 degrees. Around to two places

Andrei [34K]

Answer:

$A=39.26\ m^2$

Step-by-step explanation:

Given that,

The radius of a circle, r = 5 m

The central angle is 180 degrees

We need to find the area of a sector of a circle.

The formula for the area of sector of a circle is given by :

$A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{180}{360}\times \pi \times (5)^2\\\\A=39.26\ m^2$

So, the area of the sector of a circle is $39.26\ m^2$ .

An exam consists of 10 true-or-false questions. If a student guesses at every answer, what is the probability that he or she wil

zysi [14]

This can be solved by using the binomial distribution. The probability of guessing correctly is 0.5, and the probability of making a wrong guess is also 0.5.
$P(6\ correct)=10C6\times(\frac{1}{2})^{6}\times(\frac{1}{2})^{4}=\frac{210}{1024}=0.205$
