Answer:
A t-score of 2.0244 should be used to find the 99% confidence interval for the population mean
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 39 - 1 = 38
Now, we have to find a value of T, which is found looking at the t table, with 38 degrees of freedom(y-axis) and a confidence level of 0.99(
). So we have T = 2.0244.
A t-score of 2.0244 should be used to find the 99% confidence interval for the population mean
Since this is a triangle all the angles within the triangle add up to 180 degrees so....
82+(9x+2)+(7x)=180
82+2+16x=180
16x+84=180
16x=96
X=6
If we plug in X to angle(9x+2) and angle (7x) we will get 56 and 42. We can get angle 2 by subtracting 180-42 which is 138
FINAL ANSWER: 138 degrees

Answer:
x=-45
Step-by-step explanation:
You do inverse operation. Since x/9=-5, you would have to multiply -5 by 9 to get -45 because multiplication is the inverse of division.
Answer:
There are 8 possible combinations.
Look at this example:
2 sandwiches: PB&J, turkey sandwich
4 drinks: soda, water, lemonade, tea
1 dessert: cake
all 8 combos:
- PB&J, soda, cake
- PB&J, water, cake
- PB&J, lemonade, cake
- PB&J, tea, cake
- turkey sandwich, soda, cake
- turkey sandwich, water, cake
- turkey sandwich, lemonade, cake
- turkey sandwich, tea, cake
hope this helps
