Answer:

n=16

Step-by-step explanation:

Let's solve your equation step-by-step.

1/ 2 n−3=5

Step 1: Add 3 to both sides.

1/ 2 n−3+3=5+3

1/ 2 n=8

Step 2: Multiply both sides by 2.

2*( 1/ 2 n)=(2)*(8)

n=16

Answer:

n=16

Answer:

n=16

Step-by-step explanation:

First you have to do 3+-3 to cross it out

then you have to add 3 to 5

lastly divide 8 and 1/2

Then you get your answer.

Answer:

3/4x6=4.5

Step-by-step explanation:

If Keri pours 6 glasses that each contain 3/4 cups than If she where to pour all of them than It would be 3/4*6 to represent the amount of cups to glasses and then the answer would be 4.5 C.

In all glasses combined their will be 4.5 cups of water!

Fractions are written as a ratio of two integers.  If Keri pours 6 glasses of juice, she must have poured 4.5 cups of juice

Fractions are written as a ratio of two integers.

If Keri pours 6 glasses of juice and each glass contains 3/4 cup, hence the total cups of juice poured is expressed as:

Total cups of juice poured = 3/4 * 6

Total cups of juice poured = 4.5

Hence if Keri pours 6 glasses of juice, she must have poured 4.5 cups of juice

Answer:

false

Step-by-step explanation:

Answer:

a) The mean is 0.8.

b) The standard deviation is 0.0365.

c) Normal

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes 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]

80% of Americans over the age of 25 have earned a high school diploma.

This means that [tex]p = 0.8[/tex]

Suppose we take a random sample of 120 Americans

This means that [tex]n = 120[/tex].

Question a:

The mean is:

[tex]\mu = p = 0.8[/tex]

The mean is 0.8.

Question b:

The standard deviation is:

[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.8*0.2}{120}} = 0.0365[/tex]

The standard deviation is 0.0365.

Question c:

By the Central Limit Theorem, approximately normal.

a) The mean is 0.8.

b) The standard deviation is 0.0365.

c) Normal

Here, we have,

we know that,

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean x and standard deviation σ, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean x and standard deviation s = σ/√n .

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 x=p and standard deviation s=√p(1-p)/n

80% of Americans over the age of 25 have earned a high school diploma.

This means that p=0.8

Suppose we take a random sample of 120 Americans

This means that n=120.

Question a:

The mean is:

x=p=0.8

The mean is 0.8.

Question b:

The standard deviation is:

s=0.0365

The standard deviation is 0.0365.

Question c:

By the Central Limit Theorem, approximately normal.

Answer:

Option (1)

Step-by-step explanation:

Volume of a cylinder is given by the formula,

V = πr²h

Here, V = Volume

r = Radius of the circular base

h = Height of the cylinder

From the picture attached,

r = 8 in.

h = 0.5 in.

By substituting these values in the formula,

V = π(8)²(0.5)

  = 32π

  = 32(3.14)

  = 100.48 in³

Therefore, Option (1) will be the correct option.

Answer:

The minimum score required for an A grade is 83.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 72.3 and a standard deviation of 8.

This means that [tex]\mu = 72.3, \sigma = 8[/tex]

Find the minimum score required for an A grade.

This is the 100 - 9 = 91th percentile, which is X when Z has a pvalue of 0.91, so X when Z = 1.34.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.34 = \frac{X - 72.3}{8}[/tex]

[tex]X - 72.3 = 1.34*8[/tex]

[tex]X = 83[/tex]

The minimum score required for an A grade is 83.

Answer:

50.965.01

Step-by-step explanation:

Answer:

1/4

Step-by-step explanation:

For the first circle 2 x 2in = 4 to find diameter

4 x 3.14 = 12.56

6in x 2 = 12

12 x 3.14 = 37.68

simplify

12.56/37.68

6.28/18.84

3.14/9.42

So the answer is 1/4 since 3.14 x 2 = 6.28

Also since the radius is 2 times longer

Answer:

C. rectangular prism

Step-by-step explanation:

The slope of line shown in the graph is 1.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have two points from the graph as (8, 8) and (5, 5)

So, the slope of line

Slope = (5- 8)/ (5-8)

slope= (-3)/ (-3)

slope = 1

Also, rise 3 units and run 3 units

Then, slope= Rise/ Run

slope= 3/3

Slope= 1

This, the required slope is 1.

Answer:

q = 26

Step-by-step explanation:

Given the point (3, q ) lies on the line then the coordinates satisfy the equation.

Substitute x = 3, y = q into the equation

q = 8(3) + 2 = 24 + 2 = 26

Answer:

[tex]\rm q = 26[/tex]

Step-by-step explanation:

Given :-

And we need to find out the value of q. Since the point lies on the given line , it will be a solution of the line. On substituting the values of x and y , we have ,

Given line :-

[tex]\rm\implies y = 8x + 2 [/tex]

Substituting the respective values :-

[tex]\rm\implies q = 8*3 + 2 \\\\\rm\implies q = 24 + 2 \\\\\rm\implies \boxed{\rm q = 26 }[/tex]

Hence the value of q is 26 .
