Answer:
when its a linear equation
Step-by-step explanation:
20 total balls:
5 are black
17 NOT yellow
12 NOT green
20-17 = 3
20-12 = 8
5 Black + 3 yellow + 8 green = 16 balls
20 total balls - 16 balls = 4 blue balls
Ewa has 4 blue balls.
Area of triangle = (1/2)*base*height
20.335 = (1/2)*base*8.3
2*20.335 = base*8.3
(2*20.335) / 8.3 = base Use your calculator.
4.9 = base
base = 4.9cm
C and make sure next time make the pic look cleaer
It depends on what the level of significance (alpha) is.
Since alpha is not stated, I'll assume that alpha = 0.05 by default.
Because the p-value is smaller than alpha, we reject the null hypothesis.
Therefore, we conclude that the alternative hypothesis is correct and the proportion of heads is greater than 0.5
