Step-by-step explanation:
im pretty sure
215.
The 2 in 5,621 is equal to 20 while 2 in 215 is equal to 200, which is ten times the prior one.
Answer: 0.8
Step-by-step explanation:
The slope of a line passing through point A(a,b) and B(c,d) is given by :-
Given : A coordinate grid is mapped onto a video game screen, with the origin at the lower left corner.
The game designer programs a turtle to move along a linear path that passes through the points (0, 0) and (10, 8).
Then , the slope of the line that represents the turtle's path is given by :-
Hence, the slope of the line that represents the turtle's path is 0.8 .

Answer:
Correct option is (c).
Step-by-step explanation:
The experiment is conducted to determine whether a new fertilizer affects the yield of tomato plants.
The procedure involves randomly assigning the new fertilizer to 20 plants and the other 20 will be assigned the current fertilizer.
Then the mean number of tomatoes produced per plant will be recorded for each fertilizer, and the difference in the sample means will be calculated.
The collected sample data will then be used to make conclusion about the population.
The researchers main aim is to determine whether the new fertilizer is effective or not, i.e. if on using the new fertilizer the yield of tomatoes increases or not.
So, the parameter under study id the difference between tow population means.
To make inferences about the experiment the researcher can construct a two-sample <em>t</em>-interval for a difference between population means. The confidence interval has a certain specific probability of including the true parameter value.
Thus, the correct option is (c).
