Answer:
2ND SLIDE(ORANGE)
Step-by-step explanation:
1. 2x+90=180; x=45
2. 2x+88=180; x=46
3. 3x+15=180; x=55
The margin of error is 0.97849
we are given
mean=235
so,
standard deviation =7.5
so,
we know that
ME=2*standard error
and
If confidence level is 95%, then we can multiply by 1.96
so, we can multiply by 2 to get ME
now, we can use marginal error formula
now, we can plug values
and we get
Answer:
the domain is the set of x values so I believe its (3,3)
Answer:
Semicircle
Step-by-step explanation:
As we can see, the arc is bounded by the chord MO
since the chord passes through the center of the circle, we have it that the chord is a diameter
Mathematically, an arc bounded by a diameter represents half of a circle
So we can conclude that the arc MNO in circle C is a semicircle
