Answer:
49.55
Step-by-step explanation:
okay so, what we do is
Get 15% of 23
Get 15% of 32
15% of 23 is 3.45
15% of 32 is 4.80
Now we do
23 - 3.45
32 - 4.80
23 - 3.45 is 19.55
32 - 4.80 is 27.2
This is the part im not 100% on
27.20 + 19.55 is 46.75
6% of 46.75 is 2.80
46.75 + 2.80 is 49.55
Now i dont know if its that way or if you apply the 6% sale tax to each individual item
Answer:
Step-by-step explanation:
For this case we have the following info given:
Weight before diet 180 125 240 150
Weight after diet 170 130 215 152
We define the random variable 
and we can calculate the inidividual values:
D: 10, -5, 25, -2
And we can calculate the mean with this formula:
And the deviation with:
And after replace we got:
And the confidence interval for this case would be given by:
The degrees of freedom are given by:
For the 95% of confidence the value for the significance is 
and the critical value would be 
. And replacing we got:
<h3>
Answer: B) 30</h3>
Any amount of rotation will not change the angle between the two spokes. This is because each piece of the wheel moves in unison as the rotation is applied. Nothing changes about the wheel. Imagine instead of rotating the wheel, we instead rotated the camera that is capturing the wheel (or the person looking at the wheel rotates their head). This is a good way to see how the wheel itself isn't changing at all, but instead rather just the look of it is changing.
The lengths of sides of a 30°-60°-90° triangle have the ratio 1 : √3 : 2. Multiplying these values by 5 tells you the sides have the lengths 5 : 5√3 : 10.
The length x of the middle-length side is ...
c. 5√3
