Step-by-step explanation:
Answer:
[-1, 7]
Step-by-step explanation:
If you mean ...
y = 4sin(2x) +3
then you can substitute the range of the sine function into the equation and evaluate it to find the range of y.
The range of sin( ) is [-1, 1], so the range of y is ...
4[-1, 1] +3 = [4(-1)+3, 4(1)+3] = [-1, 7]
_____
<em>Comment on the problem statement</em>
The range of y = 4sin²(x)+3 will be different, and the range of 4sin(2x+3) will be different yet. It is usually a good idea to use parentheses around function arguments.
Answer:
I think it is F (x)=2/3+ x+ c

Answer:
We are given that Among 180 homes in Hyde Park, 25 were found to have unsafe radon levels. Among 230 homes in La Grange, 50 were found to have unsafe radon levels.
Claim : the two towns have different rates of unsafe radon levels.
Let and be the rates of unsafe radon levels of Hyde Park and LaGrange respectively .
Among 180 homes in Hyde Park, 25 were found to have unsafe radon levels
So,
Among 230 homes in La Grange, 50 were found to have unsafe radon levels.
So,
We will use Comparing Two Proportions
Formula of test statistic :
Substitute the values
test statistic :
test statistic : −2.053
Refer the z table for p value
p value = 0.0202
α= 0.05
Since p value < α
So, we reject the null hypothesis that the two towns have same rates of unsafe radon levels.
So, Claim is true.
