Answer:
D. Cannot be determined without seeing the data.
Step-by-step explanation:
Option “D” is correct because age is a quantitative variable but if we look at the exact number or exact age of the car then the car’s age is quantitative discrete but if we look at the age of the car by going a number of years then it will be continuous. Therefore, without getting the exact information of the age of the car we cannot predict the type of variable. So the option “D” best fit for the answer.
Answer:
a) reject H0
Step-by-step explanation:
The null and alternative hypotheses:
H0: the relative risk for moderate beer drinkers as compared to nondrinkers = 1
Ha: the relative risk for moderate beer drinkers as compared to nondrinkers ≠ 1
The level of significance, α = 0.1
Since the confidence interval for the relative risk of hypertension in moderate beer drinkers as compared to nondrinkers (0.47 to 0.90) does not contain the relative risk of 1, the null hypothesis will be rejected at the specified level of significance, 0.1. Therefore, the conclusion is to reject H0.
Answer:
Find below the calculations of the two areas, each with two methods. The results are:
Explanation:
<u>A) Method 1</u>
When you are not given the height, but you are given two sides and the included angle between the two sides, you can use this formula:
Where, 
is the measure of the included angle.
1. <u>Upper triangle:</u>
2. <u>Lower triangle:</u>
<u></u>
<u>B) Method 2</u>
You can find the height of the triangle using trigonometric properties, and then use the very well known formula:
Use it for both triangles.
3. <u>Upper triangle:</u>
The trigonometric ratio that you can use is:
Notice the height is the opposite leg to the angle of 60º, and the side that measures 100 units is the hypotenuse of that right triangle. Then:
3. <u>Lower triangle:</u>

Answer:
4 and 6
Step-by-step explanation:
Let integers be x and x+2 Then:-
x + x + 2 = 3(x + 2) - 2x
2x + 2 = 3x + 6 - 2x
2x + 2 = x + 6
x = 4
The numbers are 4 and 6.
Answer: 1, 8, 64, 512
Step-by-step explanation:
1^3 = 1 * 1 * 1 = 1
2^3 = 2 * 2 * 2 = 8
4^3 = 4 * 4 * 4 = 64
8^3 = 8 * 8 * 8 = 512
