Answer:
27 chocolate cake and 12 pecan cake
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The arcsine (
) function of x is defined as the inverse sine function of x when -1≤x≤1.
So, when

we have that

This gives us the domain
of the function 
The range of the function
is
so the range of the function
is the same (options A and C are false).
When x=-4,

So, option B is false and option D is true.
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.
5(8x-2)=270
distribute the 5 into 8x-2
5*8x-5*2=270
you get
40x-10=270
combine like terms
40x=280
divide both sides by 40 to find x
x=7
Answer:
x = 9
Step-by-step explanation:
Step 1: Write equation
-4 - x = -13
Step 2: Solve for <em>x</em>
<u>Add 4 to both sides:</u> -x = -9
<u>Divide both sides by -1:</u> x = 9
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-4 - 9 = -13
-13 = -13
