Answer:
6
Step-by-step explanation:
Since all the angles are the same value, we can equal them to each other: x+2 = 8, which will give us x = 6.
(1/2)⁵ =
(1/2 · 1/2 · 1/2 · 1/2 · 1/2) =
(1 · 1 · 1 · 1 · 1) / (2 · 2 · 2 · 2 · 2) =
1 / 32 .
Correlation coefficient helps us to know how strong is the relation between two variables. The strength of the model is a strong positive correlation.
<h3>What is the correlation coefficient?</h3>
The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
- 1 indicates a strong positive relationship.
- -1 indicates a strong negative relationship.
- A result of zero indicates no relationship at all, therefore, independent variable.
Hence, the strength of the model is a strong positive correlation.

Answer:
Marcus invited 40 and Laticia invited 28
Step-by-step explanation:
x+y=68 x+40=68
x=y-12 -40 -40
y-12+y=68 x=28
2y-12=68
+12 +12
2y=80
2 2
y=40
First plug in 2 for r like so:
-9(2) - 7
To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .
First we have multiplication:
-9(2) - 7
-9(2) = -18 <<< When multiplying a negative and positive number together you will multiply normally and the answer will have a negative sign
-18 - 7
Now for the subtraction:
-18 - 7 <<< When subtracting with a negative number you will do something called "Same-Add-Opposite." This means that you will keep the first number in the expression (in this case that is -18) the same. Then turn the subtraction sign into an addition sign. Finally you will take the "opposite" sign of the second number. When I say "opposite sign" I mean that if this number is positive it will become negative. If it was negative it will become positive.
Here is your expression after applying same - add - opposite:
-18 + (-7)
-25
