Find the z score that cuts-off the largest 9% under the standard normal curve. a) -1.34 b) 1.34 c) 0.536 d) 1.28

Answers

Answer:

b) 1.34

Step-by-step explanation:

The z score is used to determine the number of standard deviations by which the raw score is above or below the mean. If the z score is positive then the z score is above the mean while for a negative z score implies that it is below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

For the largest 9%, the score is 100% - 9% = 91% = 0.91

From the normal distribution table, the z score that corresponds to 0.91 is 1.34

how do find the domain and range from a graph, and writing it as an inequality ​

Answers

To determine the domain is the same as to determine which numbers appear as the first number (the x-value) in an ordered pair that is part of the graph.
To determine the range is the same as to determine which numbers appear as the second number (the y-value) in an ordered pair that is part of the graph.
Here are some examples:
y
≥
x
2
+
3
graph{y >= x^2+3 [-11.6, 13.72, 0.15, 12.81]}
Although it is not 100% certain from just the graph, this graph does get wider and wider. Every
x
does appear in some ordered pair on the graph. The domain is all real numbers.
The
y
values that appear start at
3
and go up. We get all numbers greater than or equal to
3
. Inequality:
y
≥
3

If you've learned interval notation, you write:
[

∞
)
x
2
+
y
2
9
≤
1
# graph{x^2 + y^2/9 <= 1 [-5.35, 7.14, -3.105, 3.14]}

graph{x^2+y^2 < 9 [-5.35, 7.14, -3.105, 3.14]}

In the bin there is a 45% chance of randomly selecting ripe avocados. If you are picking avocados from the bin, you keep inspecting avocados and stop upon finding a ripe avocado. If you buy a bag of avocados, you do not inspect the fruit until you get home and inspect the bag of avocados all at once.
1. What is the probability that you have inclusively between 2 and 3 ripe avocados from your bag of 5 avocados?
2. What is the probability that you inspect inclusively 3 and 3 avocados from the bin?

Answers

Answer:

0.6125

Step-by-step explanation:

We have,

P(ripe avocados) = 0.45 , n = 5

by binomial distribution,

P(x=k) = [tex]${\overset{n}C}_k P^k(1-P)^{n-k}$[/tex]

P(2 ≤ x ≤ 3) = P(x=2) + P(x=3)

P(x=2) = [tex]${\overset{5}C}_2(0.45)^2(0.55)^3$[/tex]

           = 10 x (0.45)² x (0.55)³

           = 0.3369

P(x=3) = [tex]${\overset{5}C}_3(0.45)^3(0.55)^2$[/tex]

           = 10 x (0.45)³ x (0.55)²

           = 0.2756

So, P(2 ≤ x ≤ 3 ) = 0.3369 + 0.2756

                          = 0.6125

10x + 36 = 8x -36
What is x?

Answers

Answer:

x= -36

Step-by-step explanation:

Hope this helps.

Answer:

[tex]x = -36[/tex]

Step-by-step explanation:

Solve for [tex]x[/tex] :

[tex]10x + 36 = 8x - 36[/tex]

-Subtract [tex]8x[/tex] from [tex]10x[/tex] :

[tex]10x - 8x + 36 = 8x - 8x - 36[/tex]

[tex]2x + 36 = -36[/tex]

-Subtract both sides of the equation by [tex]36[/tex] :

[tex]2x + 36 - 36 = -36 -36[/tex]

[tex]2x = -72[/tex]

-Take [tex]2x[/tex] divide it on both sides:

[tex]\frac{2x}{2} = \frac{-72}{2}[/tex]

[tex]x = -36[/tex]

So therefore, the value of [tex]x[/tex] is [tex]-36[/tex].

Answers

Answer:

Step-by-step explanation:

[tex]5x^{4} -30x^{2} -135[/tex]

We need to pull out 5 to make the rest easier to factor.

[tex]5(x^{4} -6x^{2} -27)[/tex]

Now we can factor.

Consider all combinations of how to get 27.

1 x 27

3 x 9

And that's it before you end up just switching the place i.e. 9 x 3 and 27 x 1

This makes it easy to see that 3 and 9 are our best choice because 9 - 3 is 6 which is our middle term in the equation.

So now we have:

[tex]5(x^{2} -9)(x^{2} +3)[/tex]

We can break down [tex]x^{2} -9[/tex] even further because it's a perfect square.

(x - 3)(x + 3)

Our final factor is

5(x - 3)(x + 3)[tex](x^{2} +3)[/tex]
