An1 = 3n^2 -7 = 3(1)^2 -7 = 3(1)-7 = -4
an2 = 3n^2 -7 = 3(2)^2 -7 = 3(4)-7 = 5
an3 = 3n^2 -7 = 3(3)^2 -7 = 3(9)-7 = 20
an4 = 3n^2 -7 = 3(4)^2 -7 = 3(16)-7 = 41
Answer:
im pretty sure its c and d
Answer:
Identifying at least one confounding variable that undermines the conclusion drawn in the fictional study is:
All students took the same comprehensive test.
Step-by-step explanation:
In a study, an independent variable causes an effect on the dependent variable. But a confounding variable is the variable that influences the independent variable as well as the dependent variable. If this third variable is not controlled, it might lead the researcher to make a wrong estimate of the relationship that exists between the independent variable and the dependent variable.
Answer:
The nearest whole would be 90
Step-by-step explanation:
If you are rounding a number, 1 -4 makes the number go down, for example 1.4 would round to 1. 5-9 would round up, for example, 1.8 would round to 2
(8*8)+(6*6) = c*c
64+36 = 100
sq root of 100 is 10
so the answer is 10 miles from his starting point
