Answer: 0.8
Step-by-step explanation:
Let's assume that 5 puzzles were solved in 5mins. That is, 1min for each puzzle to be solved.
From our assumption, our sample size will be 5.
The probability that a subject will solve more than 1 puzzle will be number of occurrence from 2 to 5 which is 4.
This gives: 4/5 = 0.8 to one decimal place.
Answer:
x = 10°
y = 35°
Step-by-step explanation:
9x + 20 + 7x = 180 (supplementary angles)
16x = 180 - 20
16x = 160
x = 10°
2y = 7x (
opposite angles)
2y = 70
y = 35°
The distance from point H to point J is 3 units.The value of n is 3.
Step-by-step explanation:
From the graph, point H is at (n,-6)
Point G location will be at (0,-6)
Point J is at (n,-3)
Observing point H(n,-6) and point J (n,-3) you notice that point J is above point H.find how much far is point H from point J.
d= √(x₂-x₁)²+(y₂-y₁)²
d=√(-3--6)²
d=√3² =√9 = 3
Distance H to J is 3 units
Point G (0,-6) and point H (n,-6) have a distance of 3 units same as point H to J
To get the horizontal length will ;
d=√ (n-0)²
d=√n² but d=3 units
3=√n²
9=n²
√9=n
3=n
