Answer:
0.0256
Step-by-step explanation:
Assuming a binomial model, with probability of success (getting a red marble) p = 0.20. The probability of obtaining 'k' successes in 'n' trials is:
For k = 3 red marbles in n = 4 trials:
The probability that the child gets exactly three red marbles is 0.0256.

Answer:
y = 8x + 8
Step-by-step explanation:
The y-intercept is already given so we have our b = 8 so y = mx + b becomes y = mx + 8. Now we need to figure out the slope so looking at the chart I need to figure out what number when multiplied by the x value and added to b equals the y value. The answer is 8 because when we multiply it by 1 and add it to 8 we are left with 16, which supports the chart. The equation in slope intercept form is now y = 8x + 8
Answer:
D. similar; proportional; congruent
Step-by-step explanation:
Any pair of figures is similar if their corresponding sides are proportional and their corresponding angles are congruent. That is the meaning of <em>similarity</em>.
