Answer:

B )  0.25 + 0.75 + 0.76 + 0.24

Step-by-step explanation:

<u>commutative law of addition:-</u>

According to the commutative property of addition,changing the order of the numbers.we are adding doesn't change the sum.

let a,b,c+d are two numbers

The commutative property condition in addition a+b+c+d = a+c+b+d

Given expression 0.25+0.76+0.75+0.24 = 0.25 + 0.75 + 0.76 + 0.24

conclusion:-  Answer B.

Select the correct interpretation of the probability of getting an 11 when a pair of dice is rolled. Interpret an event as signi
klio [65]

Answer:

c. Not significant at .055

Step-by-step explanation:

When a pair of dice is rolled, we have 6²=36 possible outcomes. Only 2 of these outcomes have a total score of 11:

  1. When the first dice is 5 and the second is 6.
  2. When the first dice is 6 and the second is 5.

Then, we can calculate the probability of getting 11 as the quotient between the successs outcomes and the total outcomes.

Then, the probability of getting 11 is:

P=\dfrac{X}{N}=\dfrac{2}{36}=0.055

This probability is not equal or less than 0.05, so it is not significant at 0.055.

The angle Johnny holds his pen on paper creates a linear pair. The measure of one angle is 13x+7. The measure of the second angl
lisov135 [29]

we know that

Angles in a linear pair are supplementary angles

So

Let

A-------> the first angle

B------> the second angle

A+B=180\\ ----> equation 1

A=13x+7\\ B=2A-1=B=26x+13

Substitute the values of A and B in the equation 1

13x+7+26x+13=180\\ 39x=180-20\\ x=\frac{160}{39}

\frac{160}{39}=4.10\ degrees

therefore

the answer is

the value of x is 4.10\ degrees

2. he starts with 83 pieces of candy

3. 53

4. on day 11

Step-by-step explanation:

1. self explanatory

2. self explanatory

3. 6*-5=-30 -30+83=53

4. put y as 28

28=-5x + 83 now solve for x

subtract 83 both sides

-55=-5x

divide -5 from both sides

11=x
