Hello!

To find our answer, let's divide.

2/3≈0.66666667

We know that 1/3 is .333333..., so .666666 is 2.3. To convert to a percent, we multiply by 100.

66.66666%

We can convert this .66666 back into 2/3.

66 2/3%

Therefore, our answer is C) 66 2/3%

I hope this helps!

Let's take the steps to go from a fraction to a decimal and then finally a percentage.

First, divide the numerator (the top portion of the fraction) by the denominator (the bottom portion of the fraction).

$\frac{2}{3} = 0.666...$

Next, multiply the quotient by 100 and tack a percent sign.

0.666... * 100 = 66.666...%

Decimal portion of the percent needs to be converted to the equivalent fraction.

0.666... = 2/3

Now the final answer is 66 2/3%

A prison official wants to estimate the proportion of cases of recidivism. Examining the records of 250 convicts, the official d

son4ous [18]

Answer:

For this sample, the estimated standard error is of 0.0277

Step-by-step explanation:

Central Limit Theorem

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

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 $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

Examining the records of 250 convicts, the official determines that there are 65 cases of recidivism.

This means that $n = 250, p = \frac{65}{250} = 0.26$

For this sample, the estimated standard error is

$s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.26*0.74}{250}} = 0.0277$

For this sample, the estimated standard error is of 0.0277

At a hockey game, a vender sold a combined total of 235 sodas and hot dogs. The number of hot dogs sold was 59 less than the num

Neko [114]

Answer:

147 sodas
88 hot dogs

Step-by-step explanation:

This problem is similar to many others in which the sum of two quantities and their difference are given. The solution can be found easily when the equations for the relations are written in standard form.

<h3>Setup</h3>

Let s and h represent numbers of sodas and hot dogs sold, respectively. The given relations are ...

s +h = 235 . . . . . combined total
s -h = 59 . . . . . . difference in the quantities

<h3>Solution</h3>

Adding the two equations eliminates one variable.

(s +h) +(s -h) = (235) +(59)

2s = 294 . . . . simplify

s = 147 . . . . . .divide by 2

h = 147 -59 = 88 . . . . h is 59 less

147 sodas and 88 hot dogs were sold.

<em>Additional comment</em>

The solution to a "sum and difference" problem is always the same. One of the numbers is half the sum of those given, and the other is half their difference. ((235-59)/2 = 88)

You can calculate simple interest in a savings account by multiplying the account balance by the interest rate by the time period the money is in the account. Here's the simple interest formula: Interest = P x R x N. P = Principal amount (the beginning balance).

The solution to 2 × 27 will be what kind of number? A. Odd B. Perfect square C. Even D. Prime

My name is Ann [436]

Answer:

C. Even

Step-by-step explanation:

Any multiple of 2 is an even number.

27 is 3³, so the result cannot be a perfect square.

The product of two numbers, neither of which is 1, cannot be prime.
