Using the spinner above, what
is the probability of spinning a 1
or 3?

Answer:

P(x=5)=0.2

Step-by-step explanation:

Binomial Distribution

Consider a random event that has only two possible outcomes. Call p to the probability that the event has a 'successful' outcome, and q to the 'unsuccessful' outcome.

It's clear that p+q=1, or q=1-p.

Now repeat the random event n times. We want to calculate the probability of getting x successful outcomes. This can be done with the following formula:

[tex]\displaystyle P_{x} = {n \choose x} p^{x} q^{n-x}[/tex]

Where

[tex]\displaystyle {n \choose x}[/tex]

Is the number of combinations:

[tex]\displaystyle {n \choose x} =_nC_x=\frac{n !}{x ! (n-x) !}[/tex]

Calculate the probability for n=10, p=0.4, x=5. It follows that q=1-p=0.6:

[tex]\displaystyle P_{5} = {10 \choose 5}\cdot 0.4^{5}\cdot 0.6^{10-5}[/tex]

[tex]\displaystyle P_{5} = 252\cdot 0.4^{5}\cdot 0.6^{5}[/tex]

[tex]P_{5} = 0.2[/tex]

P(x=5)=0.2

Answer:

Hello

Midpoint of (-8,6) and (5,-7)

P(a,b)=(x1+x2/2),(y1+y2/2)

        =(-8+5/2),(6+-7/2)

        =(-3/2),(-1/2)

Midpoint of (-8,6) and (5,-7) is (-3/2),(-1/2)

Answer:

30 in³

Step-by-step explanation:

surface area = 2(2 * 5 + 5 * u + 2 * u) = 62

2(10 + 5u + 2u) = 62

2(10 + 7u) = 62

10 + 7u = 62/2 = 31

7u = 31 - 10 = 21

so u = 21/7 = 3 in

Volume = 2 * 5 * 3 = 30 in³

The slope of the graph is $15 per hour. The linear function is given by y = 15x

A linear function is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the y intercept

The graph passes through the point (1, 15) and (8, 120) is:

y - 15 = [(120 - 15)/(8 - 1)(x - 1)

y = 15x

For 20 hours; y = 15(20) = $300

If the person got a $50 bonus and also worked some hours, the graph would change because the y intercept would be 50.

If the person got a $2 per hour rate, the graph would change because the slope would be 2.

The slope of the graph is $15 per hour.

Answer:

C. 216 m^2

Step-by-step explanation:

The formula for the volume of a right solid is area of the base multiplied by the height. Following this formula, we multiply the given area of the base (27 m^2) by the height (8 m) to get 216 m^2, which is option C.

Answer:

a)C

b)E

Step-by-step explanation:

a) You have to pick a vowel. There are three vowels and a total of 6 letters so it is 3/6 so the answer is C

b) Picking a card that is not T. None of the 6 letters are T so the probablity of picking a card with no T is 1. So the answer is E.

Step-by-step explanation:

Answer:

A) 5 times the sum of 3 and 4, then subtract 4

This is an arithmetic sequence with a common difference given by d= -7

I will start by defining my first term as u⁰=361

Now we have to think, if u⁰ is my 1st term than my 47th term would be u⁴⁶ not u⁴⁷ since i start counting from 0 and not 1.

Using the relation that describes the implicit relation of an arithmetic sequence, i can say:

u(n)=u⁰+nd where n is any number

u⁴⁶=u⁰+46d

u⁴⁶=361+46(-7)

u⁴⁶=361-322

u⁴⁶=39

Answer:

39.

Step-by-step explanation:

This is an arithmetic sequence with common difference -7

47th term = a + d(n - 1)

= 361  - 7(47-1)

= 39.

√27 - √3

= 3√3 - √3

= 2√3

I think the answer is the second one.

Answer:

1,140,000

Step-by-step explanation:

Answer:

You can't solve this without a specific value of x.

Step-by-step explanation:

Well, all that the absolute value sign means, is that you work in them like parenthesis, but when you "open them up" no matter what, the result will be positive.

So, | x - 2 | - | x - 3 | is just a showing you that you are going to have a positive answer for x - 2, and you are going to have a positive answer for x - 3.

Now, since we don't have a specific value for x, just to simplify this even more, lets just quickly substitute x = 1, just for a reference, so:

| 1 - 2 | - | 1 - 3 | = | -1 | - | -2 |

                         = 1 - 2

                         = -1

Ok, so we got that, now we can go back to the original problem. Since we really don't have a specific value for x, we can't really simplify this any further. Maybe if you had a specific value or placeholder for x, then you would be able to solve this.

Answer:

-50, -31.5, 44 I think

Step-by-step explanation:

The order from least to greatest is:

-50, -3, 1.5, 44

When the negative value increases ( from -1 to -2 ), the value in general decreases. Negative values have a lower value than non-negative numbers.
