Step-by-step explanation:

The game costs 36 units of currency. Aldo has saved 30 units, which is five-sixths (5/6) of the total cost.

The game costs 36. Aldo has saved 30, which is five-sixths of the total cost. Total cost, we can set up an equation where 5/6 of the total cost is equal to 30, and then solve for the unknown.

By setting up an equation where 5/6 of the total cost is equal to 30, we can determine the unknown total cost.The total cost, we can set up the equation (5/6)x = 30, where 'x' represents the total cost of the game. To isolate 'x', we can multiply both sides of the equation by 6/5. This gives us x = (6/5) * 30 = 36.

Therefore, the total cost of the game is 36 units of currency. Aldo's savings of 30 units represent five-sixths (5/6) of the game's cost, leaving a remaining amount of 6 units to reach the full price.

Answer: 30 inches

Step-by-step explanation:

Here is the complete question:

Caleb was building a birdhouse. He needed 2 boards that were each 6 inches long and one board that was 18 inches long. He was then able to cut the boards into pieces to use. What was the total length of the boards that he needed?

From the question, we are informed that Caleb needed 2 boards that were each 6 inches long and one board that was 18 inches long.

The total length of the boards that he needed goes thus:

For the first part, we are told that Caleb needed 2 boards that were each 6 inches long. This means that he needs a total of (2 × 6 inches) = 12 inches.

We are also told that he needed one board that was 18 inches long. This mean the total length of the birds needed will be the addition of the length of all the three boards. This will be:

= 12 inches + 18 inches

= 30 inches

Increase the likelihood of rejecting the null hypothesis and increase measures of effect size.

The t statistic is the ratio of the calculated deviation of a parameter from its hypothesized value with its standard error.

In general, the likelihood of discovering a significant difference increases as the variance of the difference scores increases. A limited variation for the difference scores in a repeated-measures study suggests that the treatment has little or no effect.

Increasing the number of scores within each sample reduces the predicted standard error of the mean difference. This increases the size of the observed t, making it easier to reject the null hypothesis H0. In other words, when sample size increases, statistical power increases.

Higher t-value corresponds to a lower p-value, indicating that the difference between sample-mean (Χ) and population-mean (μ) is statistically significant (hence we reject the null hypothesis).

The value of n that makes the equation (-1/2)*n = -8 true is n = 16. We can find this answer by simple arrangement of equation.

In this equation, we have the product of (-1/2) and n equal to -8. To find the value of n, we can solve for it by dividing both sides of the equation by (-1/2). Dividing -8 by (-1/2) gives us 16. Therefore, the value of n that satisfies the equation is 16.

In summary, the answer is D) 16. By dividing both sides of the equation (-1/2)*n = -8 by (-1/2), we find that n = 16 is the value that makes the equation true.

Answer:

V = 120 cm³

Step-by-step explanation:

the volume (V) of the prism is calculated as

V = Ah ( A is the area of the base and h the height )

to find h (ON)

use Pythagoras' identity in right triangle MNO

ON² + MN² = MO²

ON² + 7.5² = 8.5²

ON² + 56.25 = 72.25 ( subtract 56.25 from both sides )

ON² = 16 ( take square root of both sides )

ON = \(\sqrt{16}\) = 4

Then

V = (4.5 × 4) × 4 = 30 × 4 = 120 cm³

The mass of aluminum with a volume of 1.50 cm³ is 4.05 grams.

To find the mass of aluminum with a volume of 1.50 cm³, we can use the formula:

Mass = Density x Volume

Given that the density of aluminum is 2.7 g/cm³ and the volume is 1.50 cm³, we can substitute these values into the formula:

Mass = 2.7 g/cm³ x 1.50 cm³

Multiplying these values, we find:

Mass = 4.05 g

Therefore, the mass of aluminum with a volume of 1.50 cm³ is 4.05 grams.

The probability that all four of them are women =  0.0060

Total number of people eligible for jury duty = 140

Number of women out of eligible 140 people = 40

So the number of men = 100

Number of jurors excused from jury duty for medical reasons = 4

That is, out of this 140 people 4 are selected and this can be done in a total of 140C4 = 15329615 ways

We need to find the probability that all four of the excused are women.

Number of ways of selecting 4 out of 40 women = 40C4 = 91390 ways

Hence probability of all four of the excused jurors being women

The 95% confidence interval for population mean is (19.8, 22.2).

The confidence interval for population mean using the Student's t-distribution is:

CI = x ± \(t_{\frac{\alpha }{2}, (n -1) }\) \(\frac{s}{\sqrt{n} }\)

Given:

x = 22

s = 3

n = 27

α = n - 1 = 26

The critical value of t for α = 0.05 and degrees of freedom, (n - 1) = 19 is:

\(t_{\frac{\alpha }{2} , (n -1)}\) = \(t_{\frac{0.05}{2,19} }\)

            = 2.093

Compute the 95% confidence interval for population mean as follows:

   CI = X + \(t_{\frac{\alpha }{2}, (n -1) }\frac{s}{\sqrt{n} }\)

⇒ CI = 21± 2.093 × 3/√27

        = 21 ± 1.20

        = (22.2, 19.8)

Thus, the 95% confidence interval for population mean is (19.8, 22.2).

There are no real values for X and Y that satisfy the given equations X + Y = 17 and XY = 164.

To find the values of X and Y in the given equations, we can use a system of equations approach.

Let's start by solving the first equation, X + Y = 17, for one variable in terms of the other. We can choose to solve for X:

X = 17 - Y

Now, substitute this expression for X in the second equation, XY = 164:

(17 - Y)Y = 164

Expanding the equation gives us:

17Y - Y^2 = 164

Rearranging the equation to a quadratic form, we have:

Y^2 - 17Y + 164 = 0

To solve this quadratic equation, we can use factoring, completing the square, or the quadratic formula. Let's use the quadratic formula:

Y = (-(-17) ± √((-17)^2 - 4(1)(164))) / (2(1))

Simplifying further:

Y = (17 ± √(289 - 656)) / 2

Y = (17 ± √(-367)) / 2

Since the expression under the square root is negative, there are no real solutions for Y. This means that there are no real values for X and Y that satisfy both equations simultaneously.

The two numbers whose sum is 495 and follows the required conditions are 450 and 45.

Let the two numbers be "AB0" and "AB," where A and B are digits, and 0 represents a zero.

The sum of the two numbers is equal to 495.

The last digit of one of the numbers is zero, which means the first number is a multiple of 10, so we can rewrite it as 10x.

If you cross off the zero from the first number, you get the second number, so the second number is AB.

Now, let's substitute the values into the equation:

10x + x = 495

Now, add the like terms, and we get,

11x = 495

Divide both sides by 11, and we get,

x = 495/11

x = 45

According to the price, it will take 3.75 hours for the prices of both stocks to be the same, assuming they continue to increase and decrease at the same rates.

To find out when the prices of both stocks will be the same, we need to set up an equation where the prices of both stocks are equal. Let's call the number of hours it takes for the prices to be equal "t".

For stock A, the price after "t" hours can be expressed as:

Price of stock A = $12.73 + ($0.06 x t)

For stock B, the price after "t" hours can be expressed as:

Price of stock B = $13.48 - ($0.14 x t)

To find the time when the prices of both stocks are equal, we can set the two equations equal to each other and solve for "t".

$12.73 + ($0.06 x t) = $13.48 - ($0.14 x t)

Simplifying this equation, we get:

$0.20 x t = $0.75

Dividing both sides by $0.20, we get:

t = 3.75 hour

The expected number of times the coin is flipped is 3.75.

Probability refers to the chance of occurrence of an event.

Let E be an event. Then, the probability of E = P(E)

=> P(E) = \(\frac{Number Of Favourable Outcomes Of E}{Total Number Of Outcomes}\)

Now,

P(Tail coming up twice) = \(\frac{1}{4}\)

P(Tail coming up twice) =  \(\frac{2}{8}\)

P(Tail coming up twice) =  \(\frac{3}{16}\)

P(Tail coming up twice) = \(\frac{4}{32}\)

P(Tail coming up twice) = \(1-\frac{1}{4}-\frac{2}{8}-\frac{3}{16}- \frac{4}{32} = \frac{3}{16}\)

Therefore, the expected number of times coin is flipped = \(2(\frac{1}{4}) + 3(\frac{2}{8}) + 4(\frac{3}{16} )+5(\frac{4}{32} )+6(\frac{3}{16} ) =\frac{15}{4} = 3.75\)
