A fair number cube has faces numbered from 1 to 6. When the number cube is rolled, the theoretical probability of it landing on

Y_Kistochka [10]

<h3>Answer: 2/3</h3>

Explanation:

The theoretical probability of landing on a multiple of three is 1/3

So the theoretical probability of not landing on a multiple of three is 1-(1/3) = 3/3-1/3 = (3-1)/3 = 2/3

We can think of 1/3 to mean "1 out of 3 times", while 2/3 means "2 out of 3 times".

-1/13-10/39 please solve for me I dont seem to get it

natima [27]

Answer:

$\frac{-1}{3}$

Step-by-step explanation:

$\frac{-1}{13} - \frac{10}{39}$

Find common denominator for 13 and 39

common denominator is 39

rewrite fractions so they have the same denominator

$\frac{-1}{13} = \frac{-3}{39}$

add them up

$\frac{-3}{39} + \frac{-10}{39} = \frac{-13}{39}$

simplify/ put in the lowest terms

$\frac{-1}{3}$

a) If the null hypothesis is true, you'll get a high P-value. b) If the null hypothesis is true, a P-value of 0.01 will oc

maxonik [38]

Answer:

a) If the null hypothesis is true, you'll get a high P-value. (it depends)

b) If the null hypothesis is true, a P-value of 0.01 will occur about 1% of the time. (false)

c) A P-value of 0.90 means that the null hypothesis has a good chance of being true. (not only has a good chance it has strong evidence)

d) A P-value of 0.90 is strong evidence that the null hypothesis is true.(true)

Step-by-step explanation:

Before i answer this question, you need to understand that p-values give you the clues to identify when you can accept the null hypothesis ( null hypothesis is true) and when you can reject the null hypothesis (null hypothesis is not true).

1. When you get a small p-value (typically ≤ 0.05) values that are less or equal to 0.05, for example 0.01, you reject the null hypothesis (null hypothesis is not true)

2. when you get a large p-value (> 0.05) values that are greater than 0.05, for example 0.94, 0.90. you can accept the null hypothesis because indicates weak evidence against the null hypothesis (null hypothesis is true).

This is the explanation:

a) if the null hypothesis is true you`ll get a high p-value only if the p-value is ≥ 0.05

b) if p value is less or equal to 0.05. Null hypothesis is not true.

c) A P-value of 0.90 means that the null hypothesis has a good chance of being true . It not only has a good chance it is strong evidence that null hypothesis is true.

d) A p-value of 0.90 is strong evidence that null hypothesis is true. p-values that are greater than 0.05 you can accept the null hypothesis (null hypothesis is true).

Find the coordinates of the midpoint of the segment whose endpoint are H(3,2) and K(9,6)

lutik1710 [3]

Answer:

midpoint P(6, 4)

Step-by-step explanation:

$\frac{x1 + x2}{2} \\ \frac{y1 + y2}{2}$

$\frac{9 + 3}{2} = 6 = x \: mid \: point \\$

$\frac{6 + 2}{2} = 4 = y \: mid \: point$

What is the median of those in the the picture please help

Molodets [167]

Answer:

Median is 24.5

Step-by-step explanation:

Median is the middle number in a set of numbers. If we have two middle numbers, we get the average. And from the question, listing them out, we have this

0,1, 2, 3,4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49.

The middle number here is 24 and 25. Getting their average will be 24.5
