The graph represents a parabola and a parabola is maximum or minimum at its vertex . So we need to check the graph , and find the point where the graph is maximum or minimum. And from the given graph , we can say that it is a downward up parabola which is minimum at its vertex . And the minimum point is (1.4). So the vertex is (1,4) .
Answer:
0.5.
Step-by-step explanation:
Number of red marbles = 50
Yellow marble = 40
Green marble = 10
Total number of marble = 50+ 40 + 10 = 100
Probability of getting yellow marble = ![\dfrac{40}{100}](https://tex.z-dn.net/?f=%5Cdfrac%7B40%7D%7B100%7D)
= 0.4
Probability of getting green marble = ![\dfrac{10}{100}](https://tex.z-dn.net/?f=%5Cdfrac%7B10%7D%7B100%7D)
= 0.1
Probability of getting either red or green marble = 0.4 + 0.1 = 0.5
Hence, the required probability is equal to 0.5.
Answer:
x = 6
Step-by-step explanation:
A = 1/2bh
36 = 1/2(12)(x)
x = 6
Th z-score is given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
hence:
z=(240-200)/20
z=2
