Lian invested an amount of money at an interest rate of 5.2% per year.

Zigmanuir [339]

Answer:

$6500

Step-by-step explanation:

Let the amount of money invested by Lian be $x

Interest rate = 5.2% per year

interest earned in first year will be 5.2% of amount of money invested by Lian .

(note: since in first year there will be no interest accrued on interest so interest for first year is simple interest )

interest earned in one year if money invested by Lian is $x

= 5.2% of $x (1)

But , it is given in one year she received interest of 338 dollars

so, 338 dollars must be equal to 5.2% of $x

equating $338 with 5.2% of $x , we have

5.2% of x = 338

=> (5.2/100) * x = 338

=>5.2 x = 338*100

=> x = 33800/5.2 = 6500.

Thus, amount of money Lian invested is $6500.

In how many ways can the letters in the word MATHEMATICS be reshuffled so that all consonants appear together?

steposvetlana [31]

Answer:

75600

Step-by-step explanation:

We are given that a word MATHEMATICS

Total letters =11

M repeated 2 times

T repeated 2 times

A repeated 2 times

Total vowels=4

Let MTHMTCS=P

Total number of ways in which MTHMTCS can be arranged= $\frac{7!}{2!2!}$

PAEAI

Total number of ways in which PAEAI can arranged= $\frac{5!}{2!}$

Total number of arrangements when all consonant appear together= $\frac{7!}{2!2!}\times \frac{5!}{2!}$

Total number of arrangements when all consonant appear together= $\frac{7!5!}{2\times 2\times 2}=\frac{7\times 6\times 5\times 4\times 3\times 2\times 1\times 5\times 4\times 3\times 2\times 1}{8}=75600$

By using formula ; $n!=n(n-1)(n-2)...2\times 1$

butalik [34]

we are given

A presidential candidate plans to begin her campaign by visiting the capitals in 4 of 47 states

so, the number of ways of selecting four specific capitals out of 47 states is

$=47C_4$

$=\frac{47!}{4!(47-4)!}$

$=178365$

now, we can find probability

so, the probability is

$=\frac{1}{178365}$ ..............Answer
