4. For a normal distribution, find the z-score that separates the distribution as follows:
Stolb23 [73]

Let \Phi(z) denote the cumulative distribution function for the standard normal distribution (mean 0, standard deviation 1). Then you're looking for <em>z</em> such that

(a) \Phi(z) = P(Z\le z) = 0.70

(b) \Phi(z) = P(Z\le z) = 0.40

(c) \Phi(z) = P(Z\le z) = 0.25

To get the corresponding <em>z</em>-score for each of 0.70, 0.40, and 0.25, take the inverse CDF of both sides:

(a) z = \Phi^{-1}(0.70) \approx 0.5244

(b) z = \Phi^{-1}(0.40) \approx -0.2533

(c) z = \Phi^{-1}(0.25) \approx -0.6745

Commutative property
IrinaK [193]

Answer:

The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer. The property holds for Addition and Multiplication, but not for subtraction and division.

A farmer wants to plant peas and carrots on no more than 200 acres of his farm. If x represents the number of acres of peas and
AfilCa [17]

Answer:

Option D.(60, 135)

Step-by-step explanation:

Let

x -----> the number of acres of peas

y ----> the number of acres of carrots

we know that

The inequality that represent the problem is equal to

x+y\leq 200

so

<em>Verify each case</em>

case A) (-50,160)

substitute the value of x and the value of y in the inequality and then compare the result

-50+160\leq 200

110\leq 200 ----> is true

The point is a solution for the inequality, but is not a viable solution because the number of acres can not be a negative number

case B) (80,160)

substitute the value of x and the value of y in the inequality and then compare the result

80+160\leq 200

240\leq 200 ----> is not true

therefore

The point is not a solution

case C) (75,-200)

substitute the value of x and the value of y in the inequality and then compare the result

75-200\leq 200

-125\leq 200 ----> is true

The point is a solution for the inequality, but is not a viable solution because the number of acres can not be a negative number

case D) (60,135)

substitute the value of x and the value of y in the inequality and then compare the result

60+135\leq 200

195\leq 200 ----> is true

therefore

The point is a viable solution
