Well the younger sister is 14 the middle is 16 and the oldest is 18
Angle L: 70°
The trigonometric ratio used to solve for NM is the tangent ratio.
NM = 57.7 [nearest tenth]
<h3>How to Apply the Trigonometric Ratios?</h3>
Using the triangle sum theorem, find angle L.
Angle L = 180 - 90 - 20 = 70°
Using the tangent ratio, we can use ∠M and LN to solve for NM
Tan 20 = 21/NM [tan ∅ = opposite/adjacent]
NM = 21/tan 20
NM = 57.7 [nearest tenth]

Step-by-step explanation:
I hope its help
It is helpful to put the 14 data values in order:
... 65, 72, 74, 75, 75, 75, 86, 89, 93, 95, 95, 96, 97, 100
Because there are an even number of data values, the median is the average of the middle two values. Those are 86 and 89, so the median is (86+89)/2 = 87.5
This in-order sequence of values also helps us identify any repeated values. All values are present only once, except 75, which is present 3 times. The value present the largest number of times is the mode. The mode is 75.
Answer:
2.5% chance of finding a defective headset
970
Step-by-step explanation:
3% of the headsets found defective.
If 280 units of that model are tested, and the manufacturer finds 273 headsets without any defects,
easy to find percent 273/280=0.975
multiply by 100
97.5 then get 100-97.5=2.5
2.5% chance of finding a defective headset
ok 1,000 units of empirical probability
so the good ones
1,000/100=1
10= 1 percent
10*97=970
970
