Answer:
Sara
Step-by-step explanation:
the assumption here being that both lines JH and FH are tangent lines to the circle, if that's the case the external angle of 34° is the angle made by the equal tangents, meaning the triangle is an isosceles with twin sides.
In an isosceles triangle the twin sides make also twin angles, so the angles at J and F are twins, and they'd be 180° - 34° = 146° total, since they're twins, each one takes half, or 73°.
Answer:
Point C
Step-by-step explanation:
At point C, the graph is changing from decreasing to increasing.
198 + (199*3) + (200*2) +(201*5) + (202*2) = 2604
frequency = 1 + 3 +2 + 5 + 2 = 13
201 = (2604 + x )/14
multiply both sides by 14
x = 201*14 = 2604 +x
x = 2814 = 2604 +x
subtract 2604 from both sides:
x = 2814 - 2604
x = 210 cm
height of new player = 210 cm
Step-by-step explanation:
Mean = 81740
Standard deviation = 4590
Sample size = 15
Alpha level = 1-0.95 = 0.05
Df = 15-1 = 14
Critical value:
alpha/2 = 0.05/2 = 0.05
t0.025
t critical value = 2.145
Margin of error ME
2.145 x 4590/√15
2.145 x 4590/3.873
ME = 2542.09
Confidence interval
Lower CI = mean - ME
= 81740-2542.09
= 79197.91
Upper CI = mean + ME
= 81740+2542.09
= 84282.09
[ 79197.91, 84282.09]
B.
Using excel, exact answer for CI
Lower limit = 79198.142724212173
Upper limit = 84281.8572757827
C.
The assumptions to be made from the population are that
1. Samples are random
2. These samples are gotten from an approximately normal distribution
