Vertical angles are congruent.
10x+60=30x-20
20x=80
x=4
All four angles add up to 360 degrees.
360-100-100=360-200=160
160/2=80
100, 100, 80, 80
Answer:
Percentage error in the student measurement = 2%
Step-by-step explanation:
Percentage error = (change in length) / actual length × 100
Approximate length =294 feet
Actual length = 300 feet
Percentage error = (change in length) / actual length × 100
= (300 feet - 294 feet) / 300 feet × 100
= 6/300 × 100
= 0.02 × 100
= 2%
Percentage error in the student measurement = 2%
Answer:
117°
Step-by-step explanation:
Angle of straight line is 180°
Angles in a triangle add up to 180°
starting at right
180 - 101 = 79° at right side angle in triangle
now solving left side angle
180 - 38 - 79 = 63°
now solving x using left side angle, must add to 180°
x + 63 = 180°
x = 117°
Answer:
multiply by 4 then its 48/100 then I think its 48 percent
Step-by-step explanation:
multiply 4 to get 48 multiplying 12 by 4 and then 48 % because it is 48 of 100 :)
Answer:
The statement is true about whether A and B are independent eventa is fourth option:
A and B are not independent events because P(A/B)=0.375 and P(A)=0.25
Step-by-step explanation:
Let A be the event that the person rides the bus to school, then:
P(A)=75/300
P(A)=0.25
Let B be the event that the person has 3 or more siblings, then:
P(B)=24/300
P(B)=0.25
P(A/B)=9/24
P(A/B)=0.375
Like P(A/B)=0.375 is different to P(A)=0.25 the events are not independent
Answer. Fourth option:
A and B are not independent events because P(A/B)=0.375 and P(A)=0.25
