Answer:

Step-by-step explanation:

If y=6 and z=3, then plug in the numbers given to the variables.

3/2 times 6, -3 + 5/3 times 3.

6= 6/1, so, you can do the same operation.

3/2 times 6/1. then subtract 3 from that.( you have to simplify them to make equal denominators)

5/3 times 3/1 then add that to your previous answer.

$1675 at 4.6% for 4 years whats the interest earned and balance amount

nignag [31]

If simple interest is paid:
Interest=Pit = 1675*0.046*4=308.20

If compounded annually
Interest=P[(1+i)^t-1]=1675*(1.046^4-1)=330.13

If compounded monthly
Interest=P[(1+i/12)^(t*12)-1]=1675*((1+0.046/12)^(4*12)-1)=337.67

Please be sure to specify the type of interest and compounding period if it is compound interest.

Stu Dent has 7 different math books, 5 different science books and 10 different engineering books. Find the number of ways to pi

zepelin [54]

Answer:

155

Step-by-step explanation:

Number of math books = 7

Number of science books = 5

Number of engineering books = 10

We need to find the number of ways to pick two books with different subjects.

Solution :

We will use combination here .

If we need to choose r objects from total n objects ,

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

So, number of ways to pick two books of same subjects = $7_{C_{2}}+5_{C_{2}}+10_{C_{2}}=\frac{7!}{2!5!}+\frac{5!}{2!3!}+\frac{10!}{2!8!}\\\\=\frac{7\times 6}{2}+\frac{5\times 4}{2}+\frac{10\times 9}{2}\\\\=21+10+45=76$

Also, number of ways to select any two books = $22_{C_{2}}=\frac{22!}{2!20!}=\frac{22\times 21}{2}=21\times 11=231$

Therefore , number of ways to pick two books with different subjects =

number of ways to select any two books - number of ways to pick two books of same subjects = 231 - 76 = 155
