Answer: three rational numbers between 3/4 and 1/6 are

1/4

1/3

1/2

Step-by-step explanation:

equalize the denominators by lcm

therefore you will get 9/12 and 3/12

Which points are 19 units apart?

Harrizon [31]

Answer:

(-14, 12) and (5, 12)

Step-by-step explanation:

From inspection of the points given, we can see that all pairs of points <u>share the same y-values</u>.

Therefore, each pair of points are on the same <u>horizontal line</u>.

To find the distance between the points, simply <u>find the difference between the x-values</u>.

Given points: (-14, 12) and (5, 12)

⇒ Difference between x-values = 5 - (-14) = 19 units

Given points: (-5, 19) and (12, 19)

⇒ Difference between x-values = 12 - (-5) = 17 units

Given points: (-20, 5) and (1, 5)

⇒ Difference between x-values = -20 - 1 = -21 = 21 units

Given points: (14, 12) and (5, 12)

⇒ Difference between x-values = 14 - 5 = 9 units

Find the standard deviation of the distribution in the following situations. (Round your answers to two decimal places.) (a) MEN

Arturiano [62]

Answer:

a) 15.579

b) 39.019

Step-by-step explanation:

a) For the top 2% the z-value from the z table

z = 2.054

thus,

z = $\frac{\textup{X-Mean}}{\sigma}$

here

X = 132

Mean = 100

thus,

2.054 = $\frac{\textup{132-100}}{\sigma}$

σ = 15.579

b) Using tables, we get for Z = 0.89 the value of 0.8133 and for Z= 0.90 the value of 0.8159

By interpolation, values for 0.815 and we get Z=0.897

thus,

z = $\frac{\textup{X-Mean}}{\sigma}$

here

X = 220

Mean = 185

thus,

0.897 = $\frac{\textup{220-185}}{\sigma}$

σ = 39.019

The volume of planet A is approximately 1.5 x 10¹⁶ cubic kilometers and the volume of planet B is 1.3 x 10⁹. How many times can

kondaur [170]

The number of times planet B can fit into planet A is; 1.15× 10⁷ times.

<h3>Volume divisions</h3>

According to the question;

The volume of planet A is given to be approximately 1.5 x 10¹⁶ km³ and the volume of planet B is 1.3 x 10⁹km³.

From the problem statement above;

It follows that the number of times planet B can fit into A is;

No. of times = 1.5×10¹⁶/1.3×10⁹.

Hence, N = 1.15× 10⁷ times.
