Answer:

Yeh that's what you have to do.....

Divide the total amount by four

Answer:

yes

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

5 multiplied by x and 5 multiplied by -3

5x - 15 = 11 -3(x - 2)

-3 multiplied by x and -3 multiplied by -2

5x - 15 = 11 - 3x + 6

Add 15 to both sides

5x = 26 - 3x + 6

Add 3x to both sides

8x = 26 + 6

Add 26 + 6

8x = 32

Divide 32 by 8

x = 4

The 100 students from a large university represent a sample.

In statistics, a sample is a subset of individuals or observations taken from a larger group known as the population. The purpose of taking a sample is to make inferences and draw conclusions about the population based on the characteristics observed in the sample.

In this scenario, the 100 students from a large university who were asked about their opinion on the new health care program represent a sample. The sample is a smaller group of individuals selected from the larger population of all students at the university. The intention is to gather insights and information about the opinions of the broader population based on the responses obtained from the sample. Statistical inference techniques can be applied to analyze the data collected from the sample and make conclusions or predictions about the entire population.

It is important to note that the sample should be representative of the population to ensure that the conclusions drawn from the sample can be generalized to the larger population accurately. The process of selecting a sample and conducting statistical analyses is an essential part of studying and understanding populations using data and statistics.

a. The bank can initially lend out $15.00.

b. The money in the economy changes by $20.00.

c. The money multiplier is 4.

d. Eventually, $80.00 will be created by the banking system from Jon's $20.00.

Let us analyze each section separately:

a. To calculate the amount of money the bank can initially lend out, we need to determine the bank's reserves.

Given that the bank keeps 25% of its money in reserves, we can find the reserves by multiplying the deposit amount by 0.25.

In this case, the deposit amount is $20.00, so the reserves would be $20.00 * 0.25 = $5.00. The remaining amount, $20.00 - $5.00 = $15.00, is the money that the bank can initially lend out.

b. When Jon deposits the $20.00 bill into the bank, the money in the economy remains unchanged because the physical currency is converted into a bank deposit. Therefore, there is no change in the total money supply in the economy.

c. The money multiplier determines the overall increase in the money supply as a result of fractional reserve banking. In this case, the reserve requirement is 25%, which means that the bank can lend out 75% of the deposited amount.

The formula to calculate the money multiplier is 1 / reserve requirement. Substituting the value, we get 1 / 0.25 = 4.

Therefore, the money multiplier is 4.

d. To calculate the amount of money created by the banking system, we multiply the initial deposit by the money multiplier. In this case, Jon's initial deposit is $20.00, and the money multiplier is 4.

So, $20.00 * 4 = $80.00 will be created by the banking system from Jon's $20.00 deposit.

The ratio of the number of boys to the number of girls at your school is 5 to 8. Which statements are accurate according to this ratio?

The ratio of number of boys to girls is \(\frac{5}{8}\). That means:

\(\frac{boys}{girls} =\frac{5}{8}\)

Let's look at the first choice.

a. If a class has 16 girls, it is reasonable to expect there are approximately 10 boys in the same class.

Make the amount as a fraction with boys over girls.

\(\frac{boys}{girls} =\frac{10}{16}\)

10 and 16 can be simplified. The greatest common factor of 10 and 16 is 2, so divide by 2.

\(\frac{boys}{girls} =\frac{10 \div 2}{16 \div 2} =\frac{5}{8}\)

Since the ratio is the same, choice a is correct.

Let's move onto the second choice.

b. In a group of 52 students, about 20 are boys.

If 20 students are boys, then the amount of girls is equal to 52 - 20, which is 32. Make the amount as a fraction with boys over girls.

\(\frac{boys}{girls} =\frac{20}{32}\)

20 and 32 can be simplified. The greatest common factor of 10 and 16 is 4, so divide by 4.

\(\frac{boys}{girls} =\frac{20 \div 4}{32 \div 4}=\frac{5}{8}\)

Since the ratio is the same, choice b is correct.

Let's go to the third choice.

c. The ratio of girls to total students is 8 to 13.

If the ratio of girls to total students is 13, that means there are 8 girls. The number of boys can be found by subtracting 8 from 13, which is 5. Make the amount as a fraction with boys over girls.

\(\frac{boys}{girls} =\frac{5}{8}\)

Since the ratio is the same, choice c is correct.

Let's go to the fourth choice.

d. The Algebra class has 24 girls and 16 boys. This is the same ratio as girls to boys in the school.

Make the amount as a fraction with boys over girls.

\(\frac{boys}{girls} =\frac{16}{24}\)

16 and 24 can be simplified. The greatest common factor of 16 and 24 is 8, so divide by 8.

\(\frac{boys}{girls} =\frac{16 \div 8}{24 \div 8} =\frac{2}{3}\)

Since the ratio is not the same, choice d is not correct.

Lastly, the fifth choice.

e. If there are 208 students in the school, it is reasonable to expect there are 128 girls.

If there are 128 girls out of 208 students, the number of boys can be found by subtracting the number of girls from the amount of total students. 208 - 128 is 80, so there are 80 boys. Make the amount as a fraction with boys over girls.

\(\frac{boys}{girls} =\frac{80}{128}\)

80 and 128 can be simplified. The greatest common factor of 80 and 128 is 16, so divide by 16.

\(\frac{boys}{girls} =\frac{80 \div 16}{128 \div 16}=\frac{5}{8}\)

Since the ratio is the same, choice e is correct.

choice a ✔

The null hypothesis for the data will be 21.62 and the alternate hypothesis is 2.02 for the p-value for the data is 0.2253 .

The charge at which anything happens is referred to as the velocity at which it happens.

The required details for mean rate :

(a) H0: µ = 21.62

Ha: µ ≠ 21.62

(b) t = -1.231

p-value = 0.2253

(c) Stop rejecting H0 right now. No longer significantly different from the domestic water tariff in Tulsa, the suggested household water charge per five CCF for the entire USA.

(d) H0: µ = 21.62

Ha: µ ≠ 21.62

t = -1.231

check statistic ≥ 2.020

Don't dismiss H0 any longer. The suggested five CCF residential water charge for the entirety of the USA is no longer significantly different from the five CCF residential water tariff in Tulsa.

The P-value is higher at 0.05, the level of significance. The impact in this instance is negligible. The attempt to reject the null hypothesis failed.

The conclusion is that there is insufficient statistical support to determine whether other American cities have a different mortality rate than Tulsa.

The crucial values for t at this level of significance are t=2.019.

Given that the statistic t = -1.15 is inside the acceptance range in this case, the null hypothesis is not disproved.

There are 462 ways to choose 5 books from a shelf of 12, if you cannot choose two adjacent books.

To solve this problem, we can use a technique called "complementary counting." First, let's find the total number of ways to choose 5 books from a shelf of 12. This is simply 12 choose 5, which is:
12! / (5! × 7!) = 792
Now, let's count the number of ways to choose 5 books from a shelf of 12 where two adjacent books are chosen. We can do this by treating the adjacent books as a single unit, and then choosing 4 more books from the remaining 11. This gives us:
11 choose 4 = 330
So, there are 330 ways to choose 5 books from a shelf of 12 where two adjacent books are chosen.
Finally, we can subtract this number from the total number of ways to choose 5 books to get the number of ways to choose 5 books where no two adjacent books are chosen:
792 - 330 = 462
Therefore, there are 462 ways to choose 5 books from a shelf of 12, if you cannot choose two adjacent books.

The measure of angle 8 is 83 degrees.

To find the measure of angle 8, we need to use the properties of parallel lines and transversals.

Based on the given information, angle 2 and angle 6 are corresponding angles because they are on the same side of the transversal line and are congruent.

So, we can set up an equation to find the value of x. We know that angle 2 is equal to 8x and angle 6 is equal to x^2 - 38.

Setting them equal to each other, we get:

\(8x = x^2 - 38\)

Rearranging the equation, we have:

\(x^2 - 8x - 38 = 0\)

Now, we can solve this quadratic equation for x.

Using factoring, quadratic formula, or completing the square, we find that x = -3 or x = 11.

Since angle measurements cannot be negative, we can discard -3 as a solution. Therefore, x = 11.

To find the measure of angle 8, we substitute x = 11 into the equation for angle 6:

angle \(6 = x^2 - 38\)

\(= (11)^2 - 38\)

= 121 - 38

Cizre bought 11 pounds of almond

Step-by-step explanation:

In order to solve this problem, we can first subtract the total Cizre spent, $75, by how much she spent on figs, which is $9 because she only bought a pound:

75 - 9 = 66

So, she spent $66 on almonds, but that isn't what the question is asking. Using this information, all we have to do now is divide the total spent on almonds by the unit price per pound of the almonds:

66 / 6 = 11

And our answer is: Cizre bought 11 pounds of almonds, which seems like way too much for me but I guess Cizre just really likes almonds!

The perimeter of the rectangular community garden, after the size has been altered by a factor of 20, is 130 feet.

In two-dimensional shapes, a perimeter is defined to be a closed path that surrounds or outlines a shape. The perimeter of a circle or an ellipse though is called the circumference.

The perimeter P of a rectangle is equal to two times the length l plus two times the width w [P = 2(l + w)]. The length and the width of the rectangular community garden are consecutively 2,25 and 1 feet, and the scale factor is 20.

Therefore, the perimeter of the community garden is

P = 2(l + w) · 20

The probability that a sample taken from the site will have water content above 12% and below 16% is 0.6102.

To calculate the probability that a sample taken from the excavation site will have water content above 12% and below 16%, we need to find the proportion of the normal distribution that falls between those two values.

First, we need to standardize the values by subtracting the mean and dividing by the standard deviation.

The value of 12% will be standardized as (12-14.2)/2.3 = -0.9565 and,

the value of 16% will be standardized as (16-14.2)/2.3 = 0.7826.

Using a standard normal table, we can find the probability that a standard normal variable is less than -0.9565 and 0.7826

The probability that Z < -0.9565 is approximately 0.1687

The probability that Z < 0.7826 is approximately 0.7789

Therefore, the probability that a sample taken from the excavation site will have water content above 12% and below 16% is:

P(12 < X < 16) = P(Z < 0.7826) - P(Z < -0.9565) = 0.7789 - 0.1687 = 0.6102 or 61.02%
