Step-by-step explanation:

If a sequence is an arithmetic progression (AP), there will be a common difference d between the terms.

(-0.7) - (-2.7) = 2

(1) - (-0.7) = 1.7

(2.4) - (1) = 1.4

Since the differences are not the same, there is no common difference d and it is not an AP.

If you rolled two dice what is the probability that you would roll a 4 or a 5
Masja [62]
Hello there! Given that normal dice are numbered 1-6, individually rolling a 4 or a 5 would give a 1/6 probability. That converts to about 17% as a percentage because we can multiply 1 by 100 to get 100/6, then divide 100 by 6 to get 16.6666. When rounding, that gives approximately 17%. However, if we combined probabilities, we would find that rolling a 4 or a 5 collectively gives a 2/6 probability, which is approximately 33% as a decimal.

In terms of individual probabilities, you would be 17% likely to roll one of them. In terms of collectiveness, the likelihood of rolling a 4 or 5 would render 33% on each die. If you need additional help, let me know and I will gladly assist you.

Why does the equation (x-4)^2-28=8 have two solutions?
Aliun [14]
<h3>Answer:</h3>

For your first answer it is because they are two different ways to solve the equation

<h3>Step-by-step explanation:</h3>

For Example!

<h2>Solution 1:</h2>

(x-4)² – 28 = 8The 8 is positive making it a different equation (this is like absolute value). (I am assuming you know the answer to the probelm)

<h2>Solution 2:</h2>

(x-4)² – 28 = -8

The 8 could be negative meaning that when you add the 28 to the right side it is -8+28 which will be a negative!

. The wheel is divided into eight same-sized sections, and three of those sections represent winning a gift certificate. Assumin
aivan3 [116]
<h3>Answer:  198</h3>

The probability of winning is 3/8 since there are 3 winning spaces out of 8 total.

We expect to have (3/8)*528 = 198 winners

Note how if we had 198 winners out of 528 total players, then the empirical probability of winning is 198/528 = 3/8
