Answer:
B. As likely as not
Step-by-step explanation:
52 cards in a deck (4 suits) 2 of the suits are red, and 2 are black, which means it is equally as likely to pick a black card as a red one
Hope this helps :)
False, it would be a straight line. it has to be more than that.
Question is Incomplete, Complete question is given below.
Each morning papa notes the birds feeding on his birdfeeder. so far this month he has seen 59 blue jays, 68 black crows, 12 red robins and 1 cardinal. What is the probability of a blue jay being the next bird papa sees?
Answer:
The probability of a blue jay being the next bird papa sees is 0.421
Step-by-step explanation:
Given:
Number of outcomes of Blue jays = 59
Number of outcomes of Black crows =68
Number of outcomes of red robins = 12
Number of outcomes of cardinal = 1
Total Number of Birds = Number of outcomes of Blue jays + Number of outcomes of Black crows + Number of outcomes of red robins + Number of outcomes of cardinal =
To calculate the probability, it is obtained by the formula number of outcomes / total number of possible outcomes.
Probability of of a blue jay being the next bird papa sees =
Hence, the probability of a blue jay being the next bird papa sees is 0.421
Answer:
He did not control for lurking variables and their impacts on the results of his experiment. Amount of sunlight and water received are two outside variables(or confounding variables) that may impact the growth of his plants and influence the results. He needs to apply the same amount of sunlight and water to each plant within a different planting soil in order to rule out the influence of those two variables and test the sole effect of the soil brand on the plant growth. Otherwise, it would be hard to determine whether his plant growth was because of the soil brand or the different amounts of sunlight and water received
Answer:
Slope = 4
Step-by-step explanation:
Change in Y = 4
Change in X = 1
Slope = Δy/Δx = 4/1 = 4
