Answer:
The Answer is: 78.
Step-by-step explanation:
This one makes you think!
Let n = the number.
The number is greater than 50 and less than 85:
50 < n < 85
Some of the factors are 13 and 3.
So, multiply 13 * 3 = 39.
Multiply again by 2:
39 * 2 = 78.
78 can be factored as:
13 * 3 * 2 = 78, and it is greater than 50 and less than 85.
The number is 78.
Hope this helps! Have an Awesome Day!! :-)
You are adding five to the previous number every time. -7 + 5 = -2 and so on. So the answer would be 13
Answer:
30⁰ , 60⁰ , 90⁰
Step-by-step explanation:
Let the angles x , 2x , 3x
By angle sum property:
x + 2x + 3x = 180⁰
6x = 180⁰
x = 30⁰
Angles are : 30⁰ , 60⁰ , 90⁰
Answer:
Step-by-step explanation:
A type I error occurs when the researcher rejects the null hypothesis when it is actually true.
A type II error occurs when the research fails to reject the null hypothesis when it is not true.
In this case study,
The null hypothesis is the standard deviation is less that or equal to 13min.
The alternative hypothesis would be that the standard deviation is greater than 13mins.
A type I error would occur when having done an experiment, the researcher rejects the null hypothesis when there is enough evidence that it is actually either less or equal to 13mins
A type II error would occur when the researcher fails to reject the null hypothesis when there is enough evidence that it is actually more than 13mins.
