The 99 percent confidence interval for the population mean is found from:
The answer is:
The answer would be D. This is because the perimeter of the first one 6+6=12 and 9+9=18 then add those together to get 30. Now we have the first perimeter you take 30 then subtract 3 twice to get 24. Now take 24 and divide it by 2 to get the length which is 12 aka D
Answer:
Step-by-step explanation:
"A number is<u> [WHAT?] </u>of another number." It appears the <u>WHAT??</u> is missing. If it is a word such as "twice," it can be solved in this fashion.
Let the numbers be X and Y, with Y the larger number.
A number is <u>twice</u> another number: Y = 2X
The difference of the numbers is 18: Y - X = 18
Use the first equation (Y = 2X) in the second by replacing "Y" with (2X):
Y - X = 18
2X - X = 18
X = 18
Y = 2X, so Y = 36
Answer:
0.83333333
Step-by-step explanation:
since usually if a dice is rolled 6 times. the probability of rolling a three would be 1/6th as there are even sides on a dice and even probabilities. You would divide 5 by 6 instead of 6 by 6 meaning that the probability is 0.83333 recurring
Answer:
The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.Step-by-step explanation:
The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:
cos x = BC / y
Solving for BC
BC = y cos x
BC is the distance between the Earth and the sun
