Step-by-step explanation:
Given: Total number of fluorescent colors = 7
Total number of pastel colors = 5
Since , he want three fluorescent colors and two pastel colors.
Number of ways to select r things out of n things = ![^nC_r=\dfrac{n!}{r!(n-r)!}](https://tex.z-dn.net/?f=%5EnC_r%3D%5Cdfrac%7Bn%21%7D%7Br%21%28n-r%29%21%7D)
Number of ways to choose colors = ![^7C_3\times\ ^5C_2](https://tex.z-dn.net/?f=%5E7C_3%5Ctimes%5C%20%5E5C_2)
![=\dfrac{7!}{3!4!}\times\dfrac{5!}{2!3!}\\\\=\dfrac{7\times6\times5\times4!}{3\times2\times1\times4!}\times\dfrac{5\times4\times3!}{2\times3!}\\\\=350](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B7%21%7D%7B3%214%21%7D%5Ctimes%5Cdfrac%7B5%21%7D%7B2%213%21%7D%5C%5C%5C%5C%3D%5Cdfrac%7B7%5Ctimes6%5Ctimes5%5Ctimes4%21%7D%7B3%5Ctimes2%5Ctimes1%5Ctimes4%21%7D%5Ctimes%5Cdfrac%7B5%5Ctimes4%5Ctimes3%21%7D%7B2%5Ctimes3%21%7D%5C%5C%5C%5C%3D350)
Hence, the correct option is B. 350.

7 HRS +2 HRS = 9 HRS
30 MINS + 20 MINS = 50 MINS
This is a linear function. Let diameter (inches) be x, circumference (inches) be y, observe that the value of y/x is always 3.14. For example, 15.7/5=31.4/10=...=3.14. Therefore, this is not only a function (one to one correspondence from x to y), it's also a linear function that can be represented as y=3.14x.
Step-by-step explanation:
If r=2 and h =7 then Surface area= A= 2pi* r* h +2pi *r^2=113.1 ft^2
