Answer:
<u>Alternative hypothesis 1</u>: the mean amperage at which the fuses burn out is > 40 amperes.
<u>Alternative hypothesis 2</u>: the mean amperage at which the fuses burn out is < 40 amperes.
Step-by-step explanation:
Recall that the null hypothesis is the fact you want to refute and is in doubt.
So, in this specific case, <em>the null hypothesis would be that the mean amperage at which the fuses burn out is 40 amperes.
</em>
The alternative hypothesis are those that want to refute the null hypothesis, in this case there are 2:
<u>Alternative hypothesis 1:</u> the mean amperage at which the fuses burn out is > 40 amperes.
<u>Alternative hypothesis 2:</u> the mean amperage at which the fuses burn out is < 40 amperes.
Well i want to tell you the answer!! It is 76CJ
Answer:
40
Step-by-step explanation:
8/1/5=8x5=40
Answer:
Step-by-step explanation:
To find the perimeter of the shaded region, we must add all the sides up.
The straight side of the shaded region is 80 meters by 80 meters because the radius of the circle is 80 meters.
The curved side is one half of the semicircle circumference, so the length is:
length of curved side = 
= (1/4) * 502. 65482 meters = 125.6637m
Thus the perimeter is the sum of all the side lengths:
125.6637 + 80 + 80 = 286 meters (approximated)
Hope that helps!
So AC and BC are equal length.
So because of symmetry the CO line segment is the height of the triangle.
Also AB=6 And as O is the center of the circle AO=AB=6/2=3
OC= 3 (as it is also the radius of the circle)
Area = 6*3/2 (height * base /2)=9
