You would use order or operations to solve this problem
4 to the second power is 16 -------> 12+16= 28
Your answer would be 28
Answer:
Ecological correlation
Step-by-step explanation:
According to a different source, the options that come with this question are:
- Ecological correlation
- Extrapolation
- Lurking variable
- Influential observation
Sarah should be careful about the use of an ecological correlation. An ecological correlation describes two variables that are group means, as opposed to a correlation between two variables that describe individuals. In this case, Sarah did pick 75 random students in each state. However, she then obtained the height and weight means for each state, and proceeded to compare these. Therefore, Sarah is not comparing individual values, but means. It is important to notice this, because correlations at a group level can be much higher than those at the individual level.
So first we want to say, 8 out of the 40 flowers were perennials.
8 out of 40 is 8/40, or simplified down to 1/5.
1/5 in percentage form is 20% because 1 divided by 5 = 20%.
Answer:
a reflection across y-axis then translation of 1 unit right and 2 units up.
a clockwise rotation of 180° about the origin then a translation of 1 unit right and 3 units up
a reflection across y-axis then translation of 1 unit right and 1 unit down
a reflection across y = x then a positive rotation of 270° about the origin
Step-by-step explanation:
Ratios don't have to be "per" something, while rates are "per" something.
Ratios compare 2 or more values, as well as rates.
