Answer:

The maximum value is 14.

Step-by-step explanation:

x has to be less than or equal to -2, but x is greater than or equal to -4(This means it can be -2, -3, or -4).

y is greater than or equal to 1, but it is less than or equal to 6(so it can be from 1, 2, 3, 4, 5, or 6.)

The maximum for x is -2 and the maximum for y is 6, so...

5 times -2 equals -10.

4 times 6 is 24.

-10 + 24 = 14.

Find the area of the shaded region. The graph depicts the standard normal distribution with mean 0 and standard deviation 1

Digiron [165]

Answer:

$P(z$

And the best option would be:

$0.8708$

Step-by-step explanation:

We assume that the distribution for the random variable is:

$X \sim N (\mu=0 , \sigma=1)$

For this case we want to calculate the following probability:

$P(z$

And we can use the normal standard distribution or excel and we got:

$P(z$

And the best option would be:

$0.8708$

PLZZZZ HELPPPPPPPPP!!!! a survey asks teachers and students whether they would like the new school mascot to be a Viking or a Pa

VARVARA [1.3K]

Answer:

Step-by-step explanation:

Two events A and B are called independent, when

$P(B|A)=P(B),$

where $P(B|A)$ is the probability that B occurs given that A has already occurred.

A = randomly selected person is a student

B = randomly selected person prefer "Vikings"

B|A = randomly selected student prefer "Vikings"

Probabilities:

$P(A)=\dfrac{100}{125}=\dfrac{4}{5}=0.8\\ \\P(B|A)=\dfrac{80}{85}=\dfrac{16}{17}\approx 0.94$

Since

$0.80\neq 0.94$

we can state that events are not independent.
