Answer:
9.23712
Step-by-step explanation:
First it asks you to round to the nearest thousandth of 8.23678. So, with decimals it is tenths, hundreths, then thousandths. So the 3rd decimal place. You then will compare look at the 4th decimal place, 7, and compare it to 5. Since 7 is greater than 5, the 3rd decimal space goes up, being 8.237. Now you add the 1.00012 to get 9.23712.
Answer:
x = -3
y = -2
Step-by-step explanation:
y = 2x - 4
3y = 2x
Minus bottom from top:
2y = -4
y = -2
Plug in for y to solve for x:
3y = 2x
-6 = 2x
x = -3
Answer:
It is not correct to conclude that 3% of the population are women at least 75 years of age.
Step-by-step explanation:
To be able to calculate that P(woman and 75 years or greater) = (0.06)(0.51) you would have to know if these events are independent from one another, which we do not know.
To know if these events are independent, we would have to see if the percentage of women over 75 years is 51% compared to men.
Following the same idea, we would also have to see if, considering only the United States women population, the percentage of women over 75 years is also 6% in this subpopulation.
Since we do not have the data to state that these events are independent, conclude that 3% of the population are women at least 75 years of age is not correct.
Answer:
A. Male.
Step-by-step explanation:
For the boys:
CV = σ / μ = 60/175 = 0.3429
For the girls:
CV = σ / μ = 35 / 130 = 0.2692
Using the Method of The coefficient of variation (CV), we get 0.3429 > 0.2692. Then, the correct answer is A.
On the other hand, the smaller your range or standard deviation, the lower and better your variability is for further analysis. The range is useful, but the standard deviation is considered the more reliable and useful measure for statistical analyses. In any case, both are necessary for truly understanding patterns in your data.
