What is the nth term rule of the linear sequence <br> 6,13,20,27,34?

In a normal distribution, 95% of the data fall within how many standard deviations of the mean? O A. Three standard deviations B

Galina-37 [17]

Answer:

Two standard deviations

Step-by-step explanation:

The Z score is obtained using the mean and standard deviation, according to the empirical. Rule, which gives percentage of values that lie within an interval estimate in a normal distribution ;

one standard deviation lie within 68% of the mean

Two standard deviations lie within 95%

Three standard deviations lie within 99.7%

Hence, for the question given, 95% fall within 2 standard deviations of the mean

I don’t know how to simplify this equation

yanalaym [24]

Answer:

$7^5$

Step-by-step explanation:

According to the Product Rule for Exponents, $\frac{a^m}{a^n} = a^{m-n}$

a = 7

m = 9

n = 4

So,

$\frac{7^9}{7^4} = 7^{9-4} = 7^5$

So, the answer is $7^5$ .

Hope this helps!!!

Find the coordinates of point b on ac such that the ratio of AB to BC is 5:1

muminat

Step-by-step explanation:

To find coordinates, we need the equation of the line segment with restrictions. I think you meant to say “line segment” as lines go infinitely in 2 directions and could not be broken up into ratios. Let’s say your segment is 24 feet long. You could then label AB as 5x and BC as x since that is a ratio of 5:1 …………We’d then have an equation

5x + x = 24 … or 6x = 24…..or x = 4 which would make AB = 20 and BC = 4…but this would not give us coordinates of points.

Answer:

2.7 x $10^{-11}$

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

10 . The sign of the exponent will depend on the direction you are moving the decimal.

Mr. Jones took a survey of college students and found that 60 out of 65 students are liberal arts majors. If a college has 8,943

hammer [34]

Answer:

We can expect 8255 numbers of students are liberal arts majors.

Step-by-step explanation:

Given:

Total Number of students in the college = 8943

Now According to Mr. Jones Survey;

60 out of 65 students are liberal arts majors.

We need to find the number of students who are liberal arts majors out of total number of students in college.

Solution:

First we will find the Percentage number of students who are liberal arts majors according to survey.

Percentage number of students who are liberal arts majors can be calculated by dividing 60 from 65 then multiplying by 100.

framing above quote in equation form we get;

Percentage number of students who are liberal arts majors = $\frac{60}{65}\times 100 = 92.31\%$

Now we will find the Total number of students who are liberal arts major.

Total number of students who are liberal arts major can be calculated by Multiplying Percentage number of students who are liberal arts majors with total number of students in the college and then dividing by 100.

framing above quote in equation form we get;

Total number of students who are liberal arts major = $\frac{92.31}{100}\times 8493 \approx8255.28$

Since number of students cannot be in point, so we will round the value.

Hence We can expect 8255 numbers of students are liberal arts majors.
