Answer:
Honestly love how she's talking to another guy so she dated a guy then cheated on him now shes talking to another guy cheating on him with another guy don't waste your time on her she is a cheater
You would use PEMDAS to solve this:
0.8 x 1.5 = 1.2
4 + 1.2 - 3
5.2 - 3
2.2 is your answer
Answer:
The point estimate of the standard deviation for the population of NFL games is
Step-by-step explanation:
a) Develop a point estimate of mean fan rating for the population of NFL games
The point estimate is the mean of the sample.
The mean is the sum of the values divided by the number of values. There are 12 values, so:
The point estimate of mean fan rating for the population of NFL games is 60.08.
b. Develop a point estimate of the standard deviation for the population of NFL games (to 4 decimals).
This point estimate is the standard deviation of the sample.
The standrd deviation of a N-cardinality set is given by the following formula:
where is the element at the position k of the set and M is the mean of the set.
For this sample, we have that the standard deviation(using a calculator) is:
The point estimate of the standard deviation for the population of NFL games is
Answer:
Hi there!
Your answer is:
17= 2A-5
Alonzo is 11
Step-by-step explanation:
Frank=2A -5
Frank = 17
17= 2A-5
A = Alonzo's age
Alonzo's age is:
17= 2A-5
+5
22 = 2A
/2
11= A
Answer:
16. D
17. 5^-1 · 5^-1 and 25^-1
8^0 · 8^3 and 8^3
Step-by-step explanation:
When you multiply two same numbers with exponents, just think of it as adding up exponents.
When you divide two same numbers with exponents, just think of it as subtracting exponents.
If a parenthesis has an exponent outside, then every exponent inside the parenthesis will be multiplied by that outside parenthesis.
(5^-1)^-2 · 5^3 ÷ 5^7
5^2 · 5^3 ÷ 5^7
5^5 ÷ 5^7
5^-2
When exponents are negative, you have to flip them or put them on the other side
5^-2 = 1/5^2 = 1/25
Let's try to find the equivalent pairs
6^7 ÷ 6^-2 = 6^5
6^9 = 6^5 Not equivalent
(6^3)^0 = 6
6^0 = 1 (Any number with a zero exponent is always 1)
1 = 6 Not equivalent
5^-1 · 5^-1 = 25^-1
5^-2 = 25^-1
Flip em
1/5^2 = 1/25
1/25 = 1/25 Equivalent
8^0 · 8^3 = 8^3
8^3 = 8^3 Equivalent
4^-3 ÷ 4^2 = 4^5
4^-5 = 4^5 Not equivalent
