Answer:
D: Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.
Step-by-step explanation:
In statistics, type I error is when we reject the null hypothesis even when it is true.
Now, the claim which is the null hypothesis is that that 10 % of children suffer from a certain disorder.
This means that a type I error will be;
Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.
Answer:
B. x-intercept: -6, y-intercept: -4
Step-by-step explanation:
2x + 3y = -12
x-intercept when y = 0
2x = - 12
x = -6
y-intercept when x = 0
3y = -12
y = -4
Answer:
g(x), and the maximum is 5
Step-by-step explanation:
for given function f(x), the maximum can be seen from the shown graph i.e. 2
But for the function g(x), maximum needs to be calculated.
Given function :
g (x) = 3 cos 1/4 (x + x/3) + 2
let x=0 (as cosine is a periodic function and has maximum value of 1 at 0 angle)
g(x)= 3 cos1/4(0 + 0) +2
= 3cos0 +2
= 3(1) +2
= 3 +2
= 5 !
I can't exactly see if the 10 at the end is negative, but I'm going to assume that it is.
10x - 6y = 8
5x - 10y = -10
= (2, 2)

Answer:
Step-by-step explanation:
The second choice down is the one you want. I'm not sure why you're confused if you simply have to graph the 2 functions to see on your calculator where they intersect. Unless you don't know how to access the change of base function in a TI84...
Hit "alpha" then "window" and 5 will open up the option to enter a base on a log.
