kumpel [21]

Answer: 32760 ways.

Step-by-step explanation:

To solve this, we first determine the number of ways to select 4 countries from 15, we calculate number of ways to visit these 4 places then we multiply.

Selecting number of ways to choose 4 cities from 15 is by using the combination formula, which becomes 15C4

Number of ways to visit these 4 cities = 4!

Hence,total number of ways of visiting these 4 cities = 15C4 * 4! = 32760ways

kaheart [24]

Answer: The critical value of the test is 2.807.

Step-by-step explanation:

Since we have given that

n = 24

So, the degree of freedom v = n-1 = 24 - 1=23

Since, n>30, so we will use 't-test'.

Here, α = 0.01

so, According to t-table, we get that

$t_{\alpha ,v}=t_{0.01,23}=2.807$

If we take α, then we are taking about two tail test.

If we take $\dfrac{\alpha }{2}$ then we are talking about one tail test.

But in both the cases, the result will be same.

Hence, the critical value of the test is 2.807.

Multiply (2.5x10^-10) (7x10^-6)

serious [3.7K]

We want to multiply $2.5\cdot10^{-10}$ by $7\cdot10^{-6}$ .

The numbers are written in scientific notation. So we expect the answer also to be in scientific notation.

the multiplication of the 10's, using the exponents rule is :

$10^{-10}\cdot 10^{-6}=10^{-10+(-6)}=10^{-10-6}=10^{-16}$

the multiplication of the other 2 numbers is:

$2.5\cdot7=17.5=1.75\cdot10$

(we write the number so that it has only one digit to the left of the decimal point).

Thus,

$(2.5\cdot10^{-10})\cdot(7\cdot10^{-6})=1.75\cdot10\cdot10^{-16}=1.75\cdot10^{-15}$

Answer: $1.75\cdot10^{-15}$
