I am once again asking for your help

Mathematics
1 answer:
Ne4ueva [31]3 years ago
3 0

Answer:

(3^1/2)(3^1/4)

Step-by-step explanation:

Use the formula

\sqrt[n]{a} ^x = a^{\frac{x}{n} }

\sqrt{3}

a = 3

n = 2, we do not write it because square root is basically replacing it

x = is a period in this case period is 1

\sqrt[4]{3}

a = 3

n = 4

x = 1

Exact Form:

3^{\frac{3}{4} }

Decimal Form:

2.27950705

…

Hope it helps:)

A true-false quiz with 10questions was given to a statistics class. Following is the probability distribution for the score of a
SSSSS [86.1K]

Using the mean <u>formula and it's interpretation</u>, it is found that:

1. The mean is 7.52.

2. If we were to give this quiz to more and more students, the mean score for these students would approach 7.52.

The mean of a discrete distribution is given by the <u>sum of each outcome divided by it's respective probability</u>.

Hence, in this problem, according to the <u>distribution given</u>, the mean is:

E(X) = 5(0.06) + 6(0.12) + 7(0.33) + 8(0.29) + 9(0.13) + 10(0.07) = 7.52

The mean is 7.52.

The <em>interpretation </em>is that over many trials, the mean would approach 7.52.

Answer:

The answer is 4.25*10^−4

Step-by-step explanation:

First convert 2.5*10^-5 into decimal form

That's

2.5*10^-5 = 0.000025

0.00045 - 0.000025 = 0.000425

= 4.25*10^−4 in scientific notation

Hope this helps
