Sorry I am not completely sure on this one and I don’t want to give you the wrong answer sorry again
5
7
X3.8
26.6
So you multiply 7x8 and you get 56 then you put the 6 down and carry the 5 and then you multiply the 3x7 and you get 21 but you add the 5+21 and get 26 then you put the decimal after one number because that is how it is in 3.8
Answer:
120 y2
Step-by-step explanation:
The floor consists of a square and a triangle
area of square = 10² = 100 yd²
area of triangle = bh ( b is the base and h the height )
Here b = 4 and h = 10 , then
area = × 4 × 10 = 2 × 10 = 20 yd²
company needs 100 + 20 = 120 yd²
Answer:
This means that we are 95% confident that the mean change in HDL (high-density lipoprotein, or "good" cholesterol) of adults eating raw garlic six days a week for six months is between plus or minus 5 milligrams per deciliter of blood (mg/dl) to the sample mean.
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
For 95% confidence interval, it means that we are 95% confident that the mean of the population is between the given upper and lower bounds(margin of error) of the confidence interval.
For the case above, the interpretation of the 95% confidence interval is that we are 95% confident that the mean change in HDL (high-density lipoprotein, or "good" cholesterol) of adults eating raw garlic six days a week for six months is between plus or minus 5 milligrams per deciliter of blood (mg/dl) to the sample mean.
(6x^3-2x^2+4) <span>- (2x^3+4x^2-5)
Subtract the like terms
6x^3 - 2x^3 = 4x^3
-2x^2 - 4x^2 = -6x^2
4 - (-5) = 9
The final answer would be
4x^3 - 6x^2 + 9
