A dog named Bella has a rectangular bed that is 2 feet wide and 3 feet long. A larger dog, Kahuna, has a rectangular bed which is 5x feet wider and 8x feet longer than Bella's bed.


Which of the following equations could be used to determine the area of Kahuna's bed?

When performing a hypothesis test on the population mean (μ) when the population standard deviation (σ) is known, the null hypothesis (H0) can never be rejected if the sample mean falls within the acceptance range determined by the chosen significance level and the critical values.

In hypothesis testing for the population mean when the population standard deviation is known, the null hypothesis (H0) represents the claim or assumption that the population mean is equal to a specific value. The alternative hypothesis (Ha) states that the population mean is not equal to the specific value.

To determine whether to reject or fail to reject the null hypothesis, we compare the sample mean to the expected value under the null hypothesis. If the sample mean falls within the acceptance range determined by the chosen significance level and the critical values, we do not have sufficient evidence to reject the null hypothesis. The acceptance range is defined by the margin of error around the expected value, and it indicates the range of values that can be considered reasonably close to the expected value.

We have verified Chebyshev’s inequality for k = 2 and k = 3 when x ∼ binomial(50, 0.4).

Main answer :Using r’s "pbinom" function, we can verify Chebyshev’s inequality for k = 2 and k = 3 when x ∼ binomial(50, 0.4).The P(X ≤ μ + 2σ) and P(X ≤ μ + 3σ) values were obtained from the "pbinom" function for k = 2 and k = 3, respectively.

Supporting explanation :Chebyshev’s inequality states that for any data set, the proportion of the data within k standard deviations of the mean is at least 1 – 1/k^2, where k is a constant greater than 1. This holds true regardless of the shape of the distribution. To verify Chebyshev’s inequality for k = 2 and k = 3 when x ∼ binomial(50, 0.4), we first calculate the mean and standard deviation using the formula μ = np and σ = sqrt(npq), where n = 50, p = 0.4, and q = 0.6. Thus, μ = 20 and σ = 2.83.Then, we use the "pbinom" function in R to obtain the values of P(X ≤ μ + 2σ) and P(X ≤ μ + 3σ) for k = 2 and k = 3, respectively. For k = 2, P(X ≤ 25.66) = 0.9975, and for k = 3, P(X ≤ 28.49) = 0.9995.These values are greater than or equal to 1 – 1/k^2, where k = 2 and k = 3, respectively.

Answer:

x ≥ -8

General Formulas and Concepts:

If it is a closed dot, we use the inequality and equal sign: ≥ or ≤

If it is a open dot, we use the inequality only: > or <

Step-by-step explanation:

We can label the solutions as x.

We see starting from -8 that are solutions get larger.

Since the dot is closed, we use the greater than or equal to sign: ≥

Therefore, x has to be greater than -8 and increasing towards ∞.

Right scalene

Step-by-step explanation:

The triangle has a right angle, but no sides are equal.

Answer:

The triangle is a right scalene triangle.

Step-by-step explanation:

If any angle is marked by a little square like in the triangle's bottom left corner, that means the angle is 90° or a right angle. Since none of the angles in the triangle are equivalent, that means the right triangle is a scalene triangle. So the correct choice is a right scalene triangle.

*Keep an eye out for a pattern

The area of the triangle def round to the nearest tenth of a square unit is 10.3 square units.

When the two sides and an angle of a  triangle is known, then the area of the triangle can be found out with the following formula.

Answer:

x = 19

m<R = 17°

Step-by-step explanation:

PQR is a triangle and the sum of interior angles in a triangle is equal to 180°

m<P + m<Q + m<R = 180°

4x - 14 + 5x + 6 + x - 2 = 180° add like terms

10x - 10 = 180 add 10 from both sides

10x = 190 divide both sides by 10

x = 19

angle R is x - 2 so if we replace x with the value we found

m<R = 19 - 2 = 17°

Answer: The student got the wrong answer. ✅

Step-by-step explanation: When you add 364 and 728 together, you get 1092. To make it easier to understand, it is like having 3 piles of 100, 6 piles of 10, and 4 ones on one side, and 7 piles of 100, 2 piles of 10, and 8 ones on the other side, when you put them together you get 10 piles of 100, 8 piles of 10 and 12 ones.

To find the biggest number they have in common, you can divide both numbers by 2 and you get 182 and 364.

So the correct way to rewrite 364 + 728 is 364 * (3+2) ✅

Answer:

y = -3x+9

Step-by-step explanation:

Parallel lines have the same slope

y = -3x+2  

This is in slope intercept form where y =mx+b where m is the slope

The slope is -3

y = -3x+b

Using the point (2,3)

3 = -3(2)+b

3 = -6+b

Add 6 to each side

3+6 = b

9=b

y = -3x+9

Answer:

slope (m) = -3

3= -3(2)+b

b = 9

y=mx+b → y= -3x+9

The correct factorization of the trinomial 15x^2 - 29x + 12 over the integers is option a: (5x - 3)(3x - 4).

To factor the trinomial, we need to find two binomial factors whose product equals the given trinomial. We can use the factoring method by grouping or the quadratic formula, but in this case, we can factor the trinomial by using a combination of factors of 15 and factors of 12 that add up to -29.

The factors of 15 are 1, 3, 5, and 15, while the factors of 12 are 1, 2, 3, 4, 6, and 12. By trying different combinations, we find that -3 and -4 are suitable factors. Therefore, we can rewrite the trinomial as (5x - 3)(3x - 4), which corresponds to option a. This factorization is obtained by expanding the product of the two binomials.

Answer:

5.3

Step-by-step explanation:

Using the Pythagorean theorem \(a^{2}+b^{2}=c^{2}\) with the length of the two legs of the right triangle for a and b and the hypotenuse length for c, you can solve this equation.

First, lets call the unknown side x. Plugging in all of the value we have into the equation we get \(x^{2} +6^{2}=8^{2}\). This is the same as \(x^{2} +36=64\).

The next step is to solve for x. Subtract 36 from both sides of the equation to get \(x^{2} =28\). Then, take the square root of both sides to get \(x=\sqrt{28}\).

Finally, since you need a rational answer, put \(\sqrt{28}\) into a calculator and round to the nearest tenth for 5.3

Answer:

Step-by-step explanation:

Step one:

given

selling price = $48

discount is 50%

tax= 4.5%

Step two:

let us first compute the amount in discount

=50/100*48

=0.5*48

=$24

also, let us compute the tax added

=4.5/100*48

=0.045*48

=$2.16

The total amount Garry has to pay is

=48-24+2.16

=$26.16

Step three:

If he has $25, he cannot afford the video game, he will have a deficit of $1.16

Answer: Gary will have to pay $25.08 in all, and if he has exactly $25, he can't afford to purchase the game because he only has $25, and he has to pay $25.08. $25.08 is more than $25, so he can't afford the game.

Step-by-step explanation:

First, subtract the $48 and 50% to find how much the video game costs.

So, $48-50%=24

Then, add the price of the video game, $24, to the 4.5% tax.

24+4.5%=25.08

Thus, Gary will need to pay $25.08 in all.
