As a freshman, suppose you had to take two of four lab science courses, one of two literature courses, two of three math courses

Sergeeva-Olga [200]

Answer:

We have 252 different schedules.

Step-by-step explanation:

We know that as a freshman, suppose you had to take two of four lab science courses, one of two literature courses, two of three math courses, and one of seven physical education courses.

So from 4 lab science courses we choose 2:

$C_2^4=\frac{4!}{2!(4-2)!}=6$

So from 2 literature courses we choose 1:

$C_1^2=\frac{2!}{1!(2-1)!}=2$

So from 3 math courses we choose 2:

$C_2^3=\frac{3!}{2!(3-2)!}=3\\$

So from 7 physical education courses we choose 1:

$C_1^7=\frac{7!}{1!(7-1)!}=7$

We get: 6 · 2 · 3 · 7 = 252

We have 252 different schedules.

If the expression x^{-\frac{3}{2}}y\sqrt{36xy^2}x − 2 3 y 36xy 2 is written in the form ax^by^cax b y c , then what is the p

Mekhanik [1.2K]

Answer:

-12

Step-by-step explanation:

The given expression is

$x^{-\frac{3}{2}}y\sqrt{36xy^2}$

We have to rewrite the given function in the form of

$ax^{b}y^c$ ....(i)

then we have to find the product of a,b and c.

The given expression can be rewritten as

$x^{-\frac{3}{2}}y\sqrt{36}\sqrt{x}\sqrt{y^2}$

Using properties of exponents we get

$x^{-\frac{3}{2}}y6x^{\frac{1}{2}}y$ $[\because \sqrt[n]{a}=a^{\frac{1}{n}}]$

$6x^{-\frac{3}{2}+\frac{1}{2}}y^{1+1}$ $[\because a^ma^n=a^{m+n}]$

$6x^{-1}y^{2}$ ...(ii)

On comparing (i) and (ii), we get

$a=6,b=-1,c=2$

Product of a,b and c is

$abc=(6)(-1)(2)=-12$

Therefore, the product of a,b, and c is -12.

Ryan the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the ot

Ivahew [28]

Answer:

Both plans last for 1.25 hours (1 hour 15 minutes)

Step-by-step explanation:

Let x hours be the time needed for plan A and y hours be the time needed for plan B.

On Wednesday there were 5 clients who did Plan A and 3 who did Plan B. Thus, 5x+3y=10.

On Thursday there were 2 clients who did Plan A and 6 who did Plan B. Thus, 2x+6y=10.

Solve the sytem of two equation. Multiply the first equation by 2, the second by 5 and subtract them:

$10x+6y-10x-30y=20-50,\\ \\-24y=-30,\\ \\y=\dfrac{30}{24}=\dfrac{5}{4}=1.25\ hours.$

Therefore,

$5x+3\cdot 1.25=10,\\ \\5x=10-3.75=6.25,\\ \\x=1.25\ hours.$
