a spinner has 5 equal sections marked 1 through 5. what is the probability of not landing on 3?

Answer:

the answere is y=543.2

Step-by-step explanation:

thats it

Answer: The mode is 3

The range is 12

Step-by-step explanation:

The mode is the most frequently appearing number

3

The range is the difference between the highest and lowest numbers

12 - 0 = 12

Answer:

31.3%

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Five trials, probability of a success is 50%.

This means that [tex]n = 5, p = 0.5[/tex]

Probability of exactly two successes

This is P(X = 2). So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{5,2}.(0.5)^{2}.(0.5)^{3} = 0.313[/tex]

0.313*100% = 31.3%

Answer:

One of the possible dimensions of the full trailer could be 5 by 12 by 3.

Step-by-step explanation:

Volume = weight times height times length = 12 times 5 times 3 = 180.

Answer:

x=64°

................

=============================================================

Explanation:

Combining all of the angles shown in the diagram leads to 360 degrees. This is because there are 360 degrees in a full rotation.

Let's add up the angles shown and set the sum equal to 360. Keep in mind that the square angle marker represents 90 degrees (aka a right angle).

180+26+x+90 = 180

x+296 = 360

x = 360-296

x = 64

Answer: 2

Step-by-step explanation:

Answer:

To find the value of x, add 5 to each side.

x - 5 = 13

+5 +5

x = 18

Answer:

The standard deviation of the distribution of sample proportions is 0.0229.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

70% of all city residents support the tax increase to build a combined bus and train station.

This means that [tex]p = 0.7[/tex]

400 city residents

This means that [tex]n = 400[/tex]

What is the standard deviation of the distribution of sample proportions?

By the Central Limit Theorem:

[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.7*0.3}{400}} = 0.0229[/tex]

The standard deviation of the distribution of sample proportions is 0.0229.

Answer:

x = 16

Step-by-step explanation:

I could be wrong so sorry in advance lol but this is what I did:

I made the equation 3x + 3 = ((7x-10)/2)

I divided the 2nd equation by 2 so that it would be the same length as RZ.

after that, I got: 3x + 3 = 3.5x - 5

from there, i did basic algebra to get the answer 16

hope this helps!

Answer:

x² - 4x - 5 = 0

Width of rectangle = 5 inch

Length of rectangle = 2 inch

Step-by-step explanation:

Given:

Area of rectangle = 10 inch²

Length of rectangle = 2[Width of rectangle] - 8

Find:

Equation

Value of length and width

Computation;

Assume;

Width of rectangle = x

So,

Length of rectangle = 2[Width of rectangle] - 8

Length of rectangle = 2x - 8

Area of rectangle = Length × Width

10 = x(2x - 8)

2x² - 8x - 10 = 0

Divide by 2 from both side

x² - 4x - 5 = 0

x² - (5-1)x - 5 = 0

x² - 5x + x- 5 = 0

x(x - 5) + 1(x - 5)

x = 5 and x = -1

So,

Width of rectangle = 5 inch

Length of rectangle = 2x - 8

Length of rectangle = 2(5) - 8

Length of rectangle = 2 inch

Answer:

-8

Step-by-step explanation:

Plug in -4 for w,  2(-4)2+8     (2x-4x2+8)

2 x -4 x 2 =-16

-16+8= -8

Answer:

25.13 centimeters

Step-by-step explanation:

Answer:

Step-by-step explanation:

If you round it to the nearest whole number, then 17.526  becomes 18 because if the first digit after the decimal(in this case,5) is 5 or greater you round to the next whole number.

If you round it to the nearest tenth, it would result in 17.5, because if the second digit after the decimal (in this case, 2) is 5 or greater you round to the next tenth of decimal.

Hope this helps!

Answer:

Step-by-step explanation:

It can be rounded down to 17.5 if rounding to 1 decimal place. If you are rounding to the nearest whole number, you would round to 18.

Hope this helps :)

Answer:

The probability that the monthly mortgage is between 2300 and 3140 is: 0.23167

Step-by-step explanation:

Given

[tex]\mu = 2870[/tex] --- the average

[tex]\sigma = 470[/tex] --- the standard deviation

Required [Missing from the question]

Monthly mortgage is between 2300 and 3140

This is represented as:

[tex]P(2300 < x < 3140)[/tex]

This is calculated as:

[tex]P(a< x < b) = P(z_a < Z < z_b)[/tex]

[tex]P(2300< x < 3140) = P(z_b < Z < z_a)[/tex]

Calculate the z scores

[tex]x = 3140[/tex]

[tex]z = \frac{3140 - 2850}{470}[/tex]

[tex]z = \frac{290}{470}[/tex]

[tex]z = 0.6170[/tex]

[tex]x = 2300[/tex]

[tex]z = \frac{3140 - 2300}{470}[/tex]

[tex]z = \frac{840}{470}[/tex]

[tex]z = 1.7872[/tex]

So, we have;

[tex]P(2300< x < 3140) = P(1.1787 < Z < 0.6170)[/tex]

This is then calculated as:

[tex]P(a < Z < b) = P(Z < a) - P(Z <b)[/tex]

[tex]P(a < Z < b) = P(Z < 1.1782) - P(Z <0.6170)[/tex]

[tex]P(2300< x < 3140) = P(Z < 1.1782) - P(Z <0.6170)[/tex]

Using the z table:

[tex]P(Z<0.6170) =0.73138[/tex]

[tex]P(Z<1.7872) =0.96305[/tex]

[tex]P(2300< x < 3140) = 0.96305 - 0.73138[/tex]

[tex]P(2300< x < 3140) = 0.23167[/tex]

Answer:

∠TUX and ∠WXU

Step-by-step explanation:

Alternate interior angles are angles that lie on the inside of the parallel lines, but different sides.

∠TUX is on the left side.

∠YXU is on the right side.

Therefore, ∠TXU and ∠WXU are alternate interior angles.

Answer:

C. 74 sqft

Step-by-step explanation:

The bottom has a surface area of 4ft * 5ft = 20sqft

Theres two 3ft x 5ft sides and two 3ft x 4ft ones.

2 * 3ft * 5ft + 2 * 3ft * 4ft = 2 * 15sqft + 2 * 12sqft = 30sqft + 24sqft = 54sqft

Total surface of the outside is thus

20sqft + 54sqft = 74sqft
