Answer:
x=18
Step-by-step explanation:
Vertical angles are congruent. This means that they are equal to each other. So, to solve set them equal to each other and isolate x. First, set up the equation. Then, subtract x from both sides. Finally, add 11 to both sides and simplify.

B. Compatible Numbers Strategy
Step-by-step explanation:
According to learnalberta "The compatible numbers strategy is a method of estimating computations by using "friendly" or "nice" numbers that can be easily calculated mentally. Compatible numbers can be used in estimating sums, differences, products and quotients."
So the closest number to 249 that can be divided by 12 is 240
240/12= 20
9514 1404 393
Answer:
it depends. 365.05 or 3.6505×10²
Step-by-step explanation:
In the US, 365.05 is already in standard form.
In the UK, "standard form" is the same as "scientific notation", so the number would be ...
3.6505×10²
Answer:
Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while
Correlation Coefficient r value of 0.80 means a strong positive relationship
Step-by-step explanation:
Correlation Coefficient (r) signifies the strength of relationship which exists between two linear variables. The value of r ranges from - 1 to + 1 where positive and negative values signifies a positive and negative relationship relationship respectively.
The closer the r value is to either +1 or - 1, the greater the strength of the relationship while a r value of 0 means, there is no relationship between the two variables.
Hence in the scenario above :
Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while
Correlation Coefficient r value of 0.80 means a strong positive relationship
