Answer:
B. 51.1°
Step-by-step explanation:
You're gonna want to use sine on this one.
Sin(x) = 7/9
x = sin^-1(7/9)
x ≈ 51.1
Answer:
A
-2 < x ≤ 3 (All x values between -2 and 3; excluding -2 and including 3)
Step-by-step explanation:
I feel the answer is A because from what we know, domain is the x-intercept or x. So both C and D are not the answer because the y-intercept is not the domain, the y-intercept is the range. Next I looked at both A and B, well, if you look closely answer choice A says "excluding -2 and including 3" and choice B says "including -2 and excluding 3". I also seen on the graph that the point of (3,3) has a filled in dot and the point at (-2,-1) has an opened dot. A filled in dot always means you either have a ≥ (greater than or equal to sign) or a ≤ (less than or equal to sign). While an opened dot always means you just have < (greater than) or a > (less than) sign. So the correct answer is A!! Hope you have a fantastic rest of your day! :)))
Answer:
9/10
Step-by-step explanation:
90% is equivalent to the decimal fraction 0.90, which in turn is 90/100, or 9/10.
Answer:
The 98% confidence interval for the mean amount of money spent on lunch per week for all students is between $13.3 and $16.7.
Step-by-step explanation:
A confidence interval has the following format.
![\mu_{x} \pm M](https://tex.z-dn.net/?f=%5Cmu_%7Bx%7D%20%5Cpm%20M)
In which
is the mean of the sample and M is the margin of error.
In this problem, we have that:
![\mu_{x} = 15, M = 1.7](https://tex.z-dn.net/?f=%5Cmu_%7Bx%7D%20%3D%2015%2C%20M%20%3D%201.7)
![\mu_{x} - M = 15 - 1.7 = 13.3](https://tex.z-dn.net/?f=%5Cmu_%7Bx%7D%20-%20M%20%3D%2015%20-%201.7%20%3D%2013.3)
![\mu_{x} + M = 15 + 1.7 = 16.7](https://tex.z-dn.net/?f=%5Cmu_%7Bx%7D%20%2B%20M%20%3D%2015%20%2B%201.7%20%3D%2016.7)
The 98% confidence interval for the mean amount of money spent on lunch per week for all students is between $13.3 and $16.7.
