Answer:
I don't know for sure, but there are a bunch of different options. Here they are:
Step-by-step explanation:
1 + 39
2 + 38
3 + 37
4 + 36
5 + 35
6 + 34
7 + 33
8 + 32
9 + 31
10 + 30
11 + 29
12 + 28
13 + 27
14 + 26
15 + 25
16 + 24
17 + 23
18 + 22
19 + 21
20 + 20
Those are the options of how many volcanoes that they could have visited. They could have visited 23 volcanoes in Alaska and 17 in California. Who knows?
California only has 20 volcanoes, and Alaska has 40, so your answer will be one of these options. Hope this helps!
Answer:
16
Step-by-step explanation:
First of all, I think it was "respectively", not "respecfully", =))). A noticeable point.
From the problem, three item's costs are represented by three consecutive even integer.
Thus, we can call cost of spoiler is x, sunroof is x-2, stereo is x + 2. It is conditioned that x is an even number.
Since the sum of the three is 48, we have
(x-2) + x + (x+2) = 48
x+x+x -2 +2 = 48
3x =48
x=16
So the spoiler is 16; thus, the sunroof is 14 and the stereo is 18
Answer:
If i did this right the answer would be 69
I converted the inches to feet (might be my first mistake)
so i get 2.5 X 1 X 1 to get 2.5
i then multiply that by 62.4 to get 156
then 225-156 = 69
Step-by-step explanation:
Answer:
a)
b) 
c) 
Step-by-step explanation:
Part a
The significance level given is 
and the degrees of freedom are given by:
Since we are conducting a right tailed test we need to find a critical value on the t distirbution who accumulates 0.1 of the area in the right and we got:
Part b
The significance level given is 
and the degrees of freedom are given by:
Since we are conducting a left tailed test we need to find a critical value on the t distirbution who accumulates 0.01 of the area in the left and we got:
Part c
The significance level given is 
and 
and the degrees of freedom are given by:
Since we are conducting a two tailed test we need to find a critical value on the t distirbution who accumulates 0.025 of the area on each tail and we got:
