Tyler solved the following expression: ​ ​ 4x−3(2+2x) ​Step 1: 4x−3(2)+3(2x) ​Step 2: 4x−6 +6x ​Step 3: 10x−6 ​However Tyler did

not have the correct answer. Find Tyler's mistake. A In Step 1, he distributed 3 to 2x instead of −3 to 2x. B From Step 1 to Step 2, he incorrectly multiplied −3 and 2 and got an answer of −6. C From Step 2 to Step 3 he incorrectly wrote −6. The correct answer is 6. D From Step 2 to Step 3 he incorrectly added 4x and 6x and got an answer of 10x.

PLEASE HELP SOMEONE!!!
evablogger [386]

Answer:

y = -2x

Step-by-step explanation:

For direct variation:  y = kx, where k is the constant of proportionality.

Given that Y equals -12 when x equals 6, we have -12 = k(6).  Solve this for k by dividing both sides by 6:

k = -12/6 => k = -2

Then the "direct variation equation" here is y = -2x.

Approximately 12.6% of all (untreated) Jonathan apples had bitter pit in a study conducted by the botanists Ratkowsky and Martin
bagirrra123 [75]

Answer:

Step-by-step explanation:

Let n be a random variable that represents the first Jonathan apple chosen at random that has bitter pit.

a) P(X = n) = q(n-1)p, where q = 1 - p.

From the information given, probability if success, p = 12.6/100 = 0.126

b) for n = 3, the probability value from the geometric probability distribution calculator is

P(n = 3) = 0.096

For n = 5, the probability value from the geometric probability distribution calculator is

P(n = 5) = 0.074

For n = 12, the probability value from the geometric probability distribution calculator is

P(n = 12) = 0.8

c) For n ≥ 5, the probability value from the geometric probability distribution calculator is

P(n ≥ 5) = 0.58

d) the expected number of apples that must be examined to find the first one with bitter pit is the mean.

Mean = 1/p

Mean = 1/0.126 = 7.9

Approximately 8 apples
