Step-by-step explanation:
To check for equivalence, use properties of operations such as the Distributive Property. Two expression are said to be equivalent if they resulted in the same number after evaluation of each. You can both expand and factor expressions to generate equivalent expressions.
Answer:
The average of -2.5, 5.2, 1.7, and -0.8 is 0.9
Step-by-step explanation:
You are taking the mean of all the values
So you would add -2.5, 5.2, 1.7, and -0.8 all together
This gives you 3.6
Then you would divide by the number of numbers per se,
Which would give you the answer: 0.9
the ratio of cheese pizzas to pepperoni pizzas sold each week by Paul's Pizzeria is C. 9 : 4.
The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
A ratio can be written 3 ways.
1. a to b
2. a:b
3. a
----
b
Now when we are working with ratios we ALWAYS put the numbers the way the question asks.
Here, we have,
It says wat is the ratio of cheese pizzas to pepperoni pizzas sold each week, So we need to put the amount of cheese pizzas 1st, then the amount of pepperoni pizzas.
now, we get,
45:20
45 to 20
45
------
20
so, we get,
Now we will SIMPLIFY.
45 ÷ 5 = 9
20 ÷ 5 = 4
So, our new ratio would be C. 9:4.
Hence, the ratio of cheese pizzas to pepperoni pizzas sold each week by Paul's Pizzeria is C. 9 : 4.

With geometric sequences, if you divide a term by the term before it you'll get the common ratio. That's how they are all constructed, and in this problem:
So -1/4 is our common ratio.
The common ratio of the geometric sequence −320, 80, −20, 5,… is -1/4 or -0.25.
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have a geometric sequence:
−320, 80, −20, 5,…
As we know, the geometric sequence or progression follows a certain rule of arithmetic.
The common ratio = second term/first term or
First term = -320
Second term = 80
= 80/(-320)
= -1/4
The common ratio = -1/4 or -0.25
Thus, the common ratio of the geometric sequence −320, 80, −20, 5,… is -1/4 or -0.25.
