What is Percentage?

Percentage is a ratio expressed as a percentage of 100.

Total area of selling space = \(2500 ft^2\)

Percentage of space used for isles = \(30\) %

Area of space used for isles = \(\frac{30}{100} \times 2500\)

                                               = \(750 ft^2\)

Area of space left = \(2500 - 750\)

                              = \(1750 ft^2\)

Area of space reserved for each category =  \(125 ft^2\)

No of categories = \(\frac{1750}{125}\)

                            = \(14\)

14 categories can be carried

Step-by-step explanation:

one is zero and one is positive. The addition symbol indicates that you are adding a positive number

Answer:17°

17° is the answer

Answer:

\(x = 17\)

Step-by-step explanation:

Because of the Alternate Angle Theorem, the two parallel lines indicate that:

\((4x+7)^\circ = 75^\circ\)

Knowing this, we can solve for \(x\):

\(4x+7 = 75\\4x = 68\\x = \frac{68}{4}\\x = 17\)

Answer:

s²+r²=t² => r²=s²-t²= 27²-25²

The answer is D

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

'r' and 's' are legs and 't' is the hypotenuse

The Pythagorean Theorem takes the sum of the legs, squared, and sets them equal to the hypotenuse squared.

So in this problem we could start with:

r² + 25² = 27²

r² = 27² - 25²

to get 'r' by itself we take its square root, and what we do to one side of an equation we must also do to the other side, so:

r = \(\sqrt{27^2 - 25^2 }\)

In the reference frame S', which is moving relative to frame S, an object at rest at x' = 0 defines the ct' axis. The world line of this object in the S frame has a slope of 1/β, where β = v/c, with v being the velocity of S' relative to S.

In the S frame, the ct' axis is drawn to represent the world line of an object at rest at x' = 0 in the S' frame. The slope of this line can be determined using the Lorentz transformation equations. The time coordinate transformation is given by t = γ(t' + βx'), where γ = 1/√(1 - β^2) is the Lorentz factor. Since x' = 0 for the object at rest in S', we have t = γt'. Since the origins of both frames coincide, the slope of the world line in the S frame is 1/γ = 1/β, where β = v/c is the velocity of S' relative to S.

In the second part, we consider the round trip of a light pulse in the S frame. The pulse leaves the origin (x' = 0) at t' = -1 m, reflects off a mirror at x' = 1 m (event M), and returns to x' = 0 at some later time (event B). The fact that the speed of light is the same in both frames means that the world lines of the light pulse in the S' frame are at 45-degree angles to the ct' axis. Since the reflection occurs at the same location in both frames, event M lies on the x' axis drawn in the S frame. Therefore, the x' axis can be drawn by connecting the common origin with point M.

In the final part, the events (x,d) = (0,0) and (x,d) = (1 m,0) representing the endpoints of a stick at rest in frame S are plotted. In frame S, these events are simultaneous, occurring at the same time coordinate. However, in frame S', due to the relativity of simultaneity, these events are not simultaneous. The event (x',ct') = (0,0) occurs first, followed by (x',ct') = (1 m,0). The ordering of events depends on the reference frame and is relative to the observer's perspective.

Answer:

The null hypothesis: \(\mathbf{H_o: p=0.27}\)

The alternative hypothesis: \(\mathbf{H_1: p \neq 0.27}\)

Test statistics : z = −2.30

P-value:  = 0.02144

Decision Rule: Since the p-value is lesser than the level of significance; then we reject the null hypothesis.

Conclusion: We accept the alternative hypothesis and  conclude that under the same​ circumstances the proportion of offspring peas will be yellow is not equal to 0.27

Step-by-step explanation:

From the given information:

Let's state the null and the alternative hypothesis;

Since The claim is that 27%  of the offspring peas will be yellow.

The null hypothesis state that the proportion of offspring peas will be yellow is equal to 0.27.

i.e

\(\mathbf{H_o: p=0.27}\)

The alternative hypothesis  state that the proportion of offspring peas will be yellow is not equal to 0.27

\(\mathbf{H_1: p \neq 0.27}\)

The test statistics:

we are given 437 green peas and 129 yellow apples;

Hence;

\(\hat p = \dfrac{x}{n}\)

where ;

\(\hat p\) = sample proportion

x = number of success

n = total number of the sample size

\(\hat p = \dfrac{129}{437+129}\)

\(\hat p = \dfrac{129}{566}\)

\(\mathbf{\hat p = 0.2279}\)

Now; the test statistics can be computed as :

\(z = \dfrac { \hat p -p }{\sqrt {\dfrac{p(1-p)}{n} } }\)

\(z = \dfrac {0.2279 -0.27 }{\sqrt {\dfrac{0.27(1-0.27)}{566} } }\)

\(z = \dfrac {-0.043 }{\sqrt {\dfrac{0.27(0.73)}{566} } }\)

\(z = \dfrac {-0.043 }{\sqrt {\dfrac{0.1971}{566} } }\)

\(z = \dfrac {-0.043 }{\sqrt {3.48233216*10^{-4} } }\)

\(z = \dfrac {-0.043 }{0.01866} }\)

z = −2.30

C. P-value

P-value = P(Z < z)

P-value = P(Z< -2.30)

By using the ​ P-value method and the normal distribution as an approximation to the binomial distribution.

P- value = 2P(z ≤ -2.30)

P-value = 2 × 0.01072

P - value = 0.02144

Answer:

61 seats.

Step-by-step explanation:

This is an example of an arithmetic sequence.

The formula for this is an = a + (n - 1)d

Where an is the number of seats in the 19th row, a is the number of seats in the first row, n is the 19th row, and d is the common difference.

We can calculate the common difference by finding how many extra seats there are from the first row to the second. 27 - 25 = 2. So, with each additional row, there are two more seats.

a19 = 25 + (19 - 1) * 2

a19 = 25 + 18 * 2

a19 = 25 + 36

a19 = 61

So, there are 61 seats in the 19th row.

If the arrival times of Caryl's school bus are distributed on a normal curve, the standard deviation would enable Caryl to estimate the probability that her bus will arrive within 5 minutes of its scheduled arrival time on any given day.

The standard deviation is a statistic that measures the amount of variation or dispersion from the central tendency of a set of data values. A low standard deviation indicates that the data is tightly clustered around the mean or average, while a high standard deviation indicates that the data is more spread out.

The standard deviation is particularly useful when dealing with normally distributed data, as it allows us to estimate the probability of a certain range of values occurring. In this case, Caryl can use the standard deviation to estimate the probability that her bus will arrive within 5 minutes of its scheduled arrival time on any given day.

Hence, option c. standard deviation would enable Caryl to estimate the probability that her bus will arrive within 5 minutes of its scheduled arrival time on any given day.

Answer:

Grace can expect to rent an apartment with a size of approximately 710.32 square feet for $1,500 per month based on the given linear regression equation.

Step-by-step explanation:

The given linear regression equation is y=0.775x+950.25, where x represents the square footage of the apartment and y represents the monthly rental price. To find the size of the apartment Grace can expect to rent for $1,500 per month, we can substitute y with 1,500 in the equation and solve for x:

1,500 = 0.775x + 950.25

0.775x = 1,500 - 950.25

0.775x = 549.75

x = 710.32

Therefore, Grace can expect to rent an apartment with a size of approximately 710.32 square feet for $1,500 per month based on the given linear regression equation.

The power of a product property refers to how we take the product of two elements with the same base and exponents.

Remember that:

a^n

means that we need to multiply a by itself n times.

Then:

(a^n)*(a^m)

Means that we need to multiply a by itself n times, and then another m times, then we can write:

0.8133 is the probability  that a randomly chosen test taker will score between 560 and 640.

Probability is the possibility that something will happen, to put it simply. We can talk about the chance or likelihood of various outcomes when we don't know how an event will turn out. Events that follow a probability distribution are the subject of statistics.

Probability is a branch of mathematics that deals with numerical representations of how likely it is for an event to occur or for a proposition to be true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates that the event is impossible and 1 indicates certainty.

P(540< x 640)

=  P ( \(\frac{560 - 560}{90}\) < \(\frac{x - mu}{sigma}\) < \(\frac{640-560}{90}\) )

By resolving this, we will obtain a probability ranging from zero to triple zero. Therefore, the likelihood will be zero. Less than zero 89 minutes our chance of being zero is zero.
