Answer:
answer 4950
Step-by-step explanation:
first divide6600by 100 &multiply by 25 ans. is 1650
subtract 6600 by 1650 ans. is 4950
By the law of cosines, the angle

satisfies

which reduces to

which converts to approximately 77 degrees (this can be done my multiplying by 180 and dividing by pi).
Answer:
-5/7
Step-by-step explanation:
remember slope is eqaul to rise over run.
6-11 = -5 so it rose down by 5 units
10 - 3 = 7 so it ran 7 units
thus
slope= -5/7
Answer:
(27.3692 ; 44.6308)
Step-by-step explanation:
Mean, xbar = 36
Standard deviation, s = 11
Sample size, n = 12
Tcritical at 0.2, df = 12 - 1 = 11 ; Tcritical = 2.718
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/sqrt(n)
Margin of Error = 2.718 * 11/sqrt(12) = 8.6308
Confidence interval :
Lower boundary : 36 - 8.6308 = 27.3692
Upper boundary : 36 + 8.6308 = 44.6308
(27.3692 ; 44.6308)
