Answer:

a9 = 26

Step-by-step explanation:

nth term of an arithmetic sequence an = a + (n-1)d

a16 = a+15d = 12.... 1

a7 = a+6d = 30.....2

Subtract

15d - 6d = 12 - 30

9d = -18

d =-18/9

d = -2

Substitute d = -2 into 1

a + 15d = 12

a+15(-2) = 12

a - 30 = 12

a = 12 + 30

a = 42

Get a9;

a9 = a+8d

a9 = 42+8(-2)

a9 = 42 - 16

a9 = 26

hence the 9th term of the sequence is 26

Answer:

20%

Think about it. 100 divided by 25 is four so just multiply 5 times 4 and you got 20. giving you the probability of 20%. Your Welcome! And I'm not a genius it's just simple math.

Answer:

16 2/3

Step-by-step explanation:

let the time taken to be filled by both pipes be y

1/2 +1/8=1/y

(4+1)/8=1/y

5/8=y

cross multiplying

5y=8

y=8/5

Well, ( − 4) 2 − 28 = 8 has two solutions because (-4) -w = 8 = ? once determined - 4 would equal 20 + the left over which is 8. This can be solved multiple ways and even backwards.

For the the equation (-4)² - 28 = 8 the solutions are x = 2 and x = -10.

Two or more expressions with an Equal sign is called as Equation.

The equation (-4)² - 28 = 8 has two solutions because when we square -4, we get 16.

When we subtract 28 from 16, we get -12.

But if we add 28 to -12, we get 16 again.

So we have two values of x that satisfy the equation: x = -4 and x = 4.

b. We can solve the equation by adding 28 to both sides:

(-4)² - 28 + 28 = 8 + 28

Simplifying, we get:

(-4)²= 36

Taking the square root of both sides, we get:

-4 = ±6

So the two solutions are:

x = -4 + 6 = 2

x = -4 - 6 = -10

Therefore, the solutions to the equation (-4)² - 28 = 8 are x = 2 and x = -10.

b=3*(1/3) yd

c=9*(1/3) yd

So, V=7 yd^3

Answer:

First, compute the z-score:

z = (x-μ)/σ = (650-500)/100 = 150/100 = 1.5

Now look up the percentile for z = 1.5 on a z-score table (http://www.z-table.com/).  The percentile, p(z=1.5), is the percent of people who scored 650 or less.  The percent who scored more than 650 is 1-p(z=1.5).  Multiply that by the 1200 students to get the number who scored more than 650.  Round to the nearest whole number (because you can't have a fraction of a person).

For the given data the value of the z score will be 1.5

It is referred to as a measure of data dispersal since it provides information on how widely the data is dispersed.

[tex]\rm \sigma = \sqrt{\dfrac{ \sum (x_i-X)}{n}[/tex]

σ stands for the standard deviation

x  is the value from the data set

X is the data set mean

n is the number of observations

It is given that, On a standardized exam, the scores are normally distributed with a mean of 200 and a standard deviation of 50.

The Z-score of a person who scored 140 on the exam is as,

z = (x-μ)/σ

z = (650-500)/100

z  = 150/100

z  = 1.5

Thus, the value of the z score will be 1.5

Answer:

The mean is of 45.

The standard deviation is 2.28.

Step-by-step explanation:

The mean is the sum of all values divided by the number of values.

The standard deviation is the square root of the sum of the difference squared between each value and the mean, and divided by the number of values.

Mean:

[tex]M = \frac{45 + 48 + 42 + 47 + 43}{5} = 45[/tex]

The mean is of 45.

Standard deviation:

[tex]M = \sqrt{\frac{(45-45)^2 + (48-45)^2 + (42-45)^2 + (47-45)^2 + (43-45)^2}{5}} = 2.28[/tex]

The standard deviation is 2.28.
