Let z denote a random variable that has a standard normal distribution. Determine each of the probabilities below. (Round all an
Lorico [155]

Answer:

P(Z < 2.37) = 0.9911.

Step-by-step explanation:

We are given that Let z denote a random variable that has a standard normal distribution.

Let Z = a random variable

So, Z ~ Standard Normal(0, 1)

As we know that the standard normal distribution has a mean of 0 and variance equal to 1.

                          Z  =  \frac{X-\mu}{\sigma}  ~ N(0,1)

where, \mu = mean = 0

           \sigma = standard deviation = 1

Now, the probability that z has a value less than 2.37 is given by = P(Z < 2.37)

        P(Z < 2.37) = P(Z < \frac{2.37-0}{1} ) = P(Z < 2.37) = 0.9911

The above probability is calculated by looking at the value of x = 2.37 in the z table which has an area of 0.9911.

Which of the following lists all of the positive factors of 18?
babymother [125]

The square root of 18 is 4.2426, rounded down to the closest whole number is 4. Testing the integer values 1 through 4 for division into 18 with a 0 remainder we get these factor pairs: (1 and 18), (2 and 9), (3 and 6). The factors of 18 are 1, 2, 3, 6, 9, 18.

Determine the coordinates of the vertex for each quadratic function and whether the parabola has a maximum or minimum. 4. y = x²
GREYUIT [131]

Answer:

minimum, coordinates of vertex: (-3,-11)

explanation:

\sf y =x^2 +6x-2

x coordinates on vertex:

<u>solving steps</u>:

  • \sf \dfrac{-b}{2a}
  • \sf \dfrac{-6}{2(1)}
  • \sf -3

<u>Find y-coordinate on vertex:</u>

\sf y =x^2 +6x-2

\sf y =(-3)^2 +6(-3)-2

\sf y =-11

\mathrm{If}\:a < 0,\:\mathrm{then\:the\:vertex\:is\:a\:maximum\:value}

\mathrm{If}\:a > 0,\:\mathrm{then\:the\:vertex\:is\:a\:minimum\:value}

coordinates: (-3,-11) thus minimum

Nicole has x dimes and y nickels. She has at least 15 coins worth a maximum of $1
Sonbull [250]

Answer:

Step-by-step explanation:

X + Y \geq 15\\\\10X + 5Y \leq 100

we want to put it into terms of Y

y \geq 15 - x\\and\\5y \leq 100 - 10x\\y \leq 20 - 2x

the graph is in the attached image. Any point in the shaded overlap region where x is greater than or equal to 0 (assuming you cannot have negative coins) works, e.g. (2, 14)
