Answer:
The probability that a Tech High student fails math is 0.1006
Step-by-step explanation:
21% students are taking class with Mary.
Every year 4% of Mary’s students fail,
15% students are taking class with Tom
Every year 6% of Tom’s students fail.
64% students are taking class with Alex
Every year 13% of Alex's students fail.
Now we are supposed to find the probability that a Tech High student fails math.



Hence the probability that a Tech High student fails math is 0.1006
Answer:

Solution,
base=1
perpendicular=?
hypotenuse=X
now,
using Pythagoras theorem,
x^2=p^2+b^2
or, x^2=p^2+1^2
or,p^2=x^2-1
or, p=√x^2-1
tan theta=perpendicular/ base
tan theta =√x^2-1/1
tan theta=√x^2-1
z=tan theta
z=√x^2-1
Hope this helps...
Good luck on your assignment..
Answer:
sorry i only know the answer of c
it's 8.2 gallons
Step-by-step explanation:
12 gallons = 420 miles
12 gallons = 420 miles? gallons =287 miles
420 miles ÷ 12 gallons = 35miles/gallon
420 miles ÷ 12 gallons = 35miles/gallon287 miles ÷ 35 miles/gallon = 8.2 gallons
Answer:
k > -9
Step-by-step explanation:
Subtract 12 from both sides as we want to isolate k-
30 - 12 = 18
-2k < 18
Divide both sides by -2
18/-2 = -9
k > -9
Answer:
Landers' Mean: 136
Landers' Median: 133
Shakaka's Mean: 136
Shakaka's Median: 133
Step-by-step explanation:
Landers:
Least to greatest: 96, 96, 120, 133, 145, 160, 202
Mean: (96+ 96+ 120+ 133+145+ 160+202)/7 = 136
Median: Since the total numbers is odd, it's just flat out in the middle
133
Shakaka:
Least to greatest: 45, 51, 118, 121, 145, 178, 212, 218
Mean: (45+ 51+ 118+ 121+ 145+ 178+ 212+ 218)/8 = 136
Median:
(121 + 145)/2 = 133
