The value of x for the angles of the quadrilateral is: x = -4

We know that the sum of angles in a quadrilateral is 360 degrees.

The angles are given as:

(11x + 140)°

(13x + 143)°

(4x + 98)°

(11x + 135)°

Thus:

(11x + 140)° + (13x + 143)° + (4x + 98)° + (11x + 135)° = 360°

Thus:

39x + 516 = 360

39x = 360 - 516

39x = -156

x = -156/39

x = -4

A level 0.95 confidence interval is a range of values computed from sample data that will contain the true value of the parameter of interest 95% of the time. So, the correct answer is C).

A level 0.95 confidence interval is a statistical measure used to estimate the true value of a population parameter based on a sample of data. It provides a range of values that is likely to contain the true value of the parameter with a certain degree of confidence.

The level of confidence, in this case 0.95, means that if the same sampling method and data analysis were repeated multiple times, the resulting confidence intervals would contain the true population parameter in 95% of cases.

The width of the interval, or margin of error, is influenced by factors such as sample size, variability, and level of confidence. So, the correct option is C).

The Central Limit Theorem (CLT) is an important theorem in statistics because it serves as the foundation for various statistical techniques and analyses.

The CLT states that the distribution of sample means approaches a normal distribution as the sample size increases, regardless of the population's original distribution, provided that the population has finite mean and variance.
Normality:

The CLT establishes the concept of normality, which is a critical assumption in numerous statistical tests such as the t-test, z-test, and ANOVA. By knowing that the sample means are normally distributed, we can apply these tests to make inferences about population parameters.
Simplification:

Due to the CLT, we can simplify complex statistical problems by using normal distributions instead of dealing with the original population distribution.

Calculations more manageable and allows us to utilize the standard normal distribution table.
Confidence intervals:

The CLT enables us to construct confidence intervals for population parameters such as the mean.

Essential in estimating unknown population parameters based on sample data and understanding the associated uncertainty.
Margin of error:

The theorem helps in determining the margin of error for estimates, allowing us to quantify the accuracy of our estimates and make better decisions based on data.
Large sample sizes:

The CLT is particularly relevant when dealing with large sample sizes, as the distribution of sample means becomes more normal, and we can apply various statistical techniques with greater confidence.
The Central Limit Theorem is important in statistics because it enables us to assume normality, simplify problems, construct confidence intervals, determine the margin of error, and apply various statistical techniques with greater confidence, especially when dealing with large sample sizes.

The probability of drawing two aces from a well-shuffled deck of 52 cards without replacement is 0.45%.

The probability of drawing two aces from a well-shuffled deck of 52 cards without replacement can be calculated as follows:

First, we calculate the probability of drawing an ace on the first draw. Since there are four aces in the deck and 52 cards in total, the probability of drawing an ace on the first draw is:

P(Ace on first draw) = 4/52 = 1/13

Next, we need to calculate the probability of drawing an ace on the second draw, given that an ace was already drawn on the first draw. Since there are now only three aces remaining in the deck and 51 cards in total, the probability of drawing an ace on the second draw is:

P(Ace on second draw given an ace on first draw) = 3/51

To calculate the probability of drawing two aces, we multiply the probability of drawing an ace on the first draw by the probability of drawing an ace on the second draw, given that an ace was already drawn on the first draw:

P(Drawing two aces) = P(Ace on first draw) x P(Ace on second draw given an ace on first draw)

P(Drawing two aces) = (1/13) x (3/51)

P(Drawing two aces) = 0.0045 or approximately 0.45%.

Step-by-step explanation:

The formula for volume of a pyramid is 1/3(lwh), in this case, it would be 1/3(12x5x10). 12x5x10 is 600, and 1/3 of 600 is 200. Therefore, the volume is 200yds.

IM VERY SORRY IF THIS DIDN'T MAKE SENSE!

Answer:

Jessica has 400 cm^3 of material. She uses 35cm^3 to make a right triangular prism. She wants to make a second prism that is a dilation of the first prism with a scale factor of 2.5.

The volume of the first prism is 35 cm^3. Since the second prism is a dilation of the first prism with a scale factor of 2.5, its volume will be (2.5)^3 = 15.625 times greater than that of the first prism. Therefore, the volume of the second prism will be 35 x 15.625 = 546.875 cm^3.

To make the second prism, Jessica needs an additional material of 546.875 - 35 = 511.875 cm^3.

So Jessica needs an additional material of 511.875 cm^3 to make the second prism.

For an event based on order by sam for ham and coffee with different probabilities, then the probability that he will order neither ham nor coffee is equals to the 0.07.

We have sam is a regular customer at joe's diner. Let us consider two events be defined as A: sam will order ham

B: sam will order coffee

Now, the probability that sam will order ham, P( A) = 0.8

The probability that sam will order coffee, P( B) = 0.65

We have to determine the probability that he will order neither ham nor coffee.

Probability is chances of occurrence of an event. It is calculated by dividing the favourable response to total possible outcomes. Probability value always lies between 0 to 1. Apply probability law P( will order ham ) + P( will not order ham) = 1

=> Probability that sam will not order ham

[tex]P( \bar A ) [/tex] = 1 - 0.8 = 0.2

Probability that sam will not order coffee,

[tex]P( \bar A ) [/tex]= 1 - 0.65 = 0.35

Now, as we see both events A and B are independent events so, there corresponding also independent. Therefore, Probability that he will order neither ham nor coffee, [tex] P( \bar A ∩ \bar B) [/tex]

[tex]= P( \bar A) P(\bar B) [/tex]

= 0.2 × 0.35 = 0.07

Answer: 23 1/2

Step-by-step explanation:

you need to include the number of roses in the mean calculation (Ex: 22, 22, 23, 23, 23, 23, etc.)

Answer: To solve this problem, we need to use the central limit theorem to find the distribution of the sample means. The central limit theorem states that if we take random samples of size n from a population with a mean μ and a standard deviation σ, the distribution of the sample means approaches a normal distribution with a mean of μ and a standard deviation of σ/√n, as n gets larger.

In this case, we have a population of healthy humans with a mean temperature of μ = 98.6 degrees and a standard deviation of σ = 0.8 degrees. We want to find the probability that the average temperature for a sample of 130 healthy people is 98.25 degrees or higher. The sample size is large enough to use the normal distribution to approximate the distribution of the sample means.

The z-score corresponding to a sample mean of 98.25 degrees is:

z = (98.25 - 98.6) / (0.8 / sqrt(130)) = -1.91

Using a standard normal distribution table or calculator, we can find the probability that a standard normal random variable is greater than -1.91:

P(Z > -1.91) = 0.9719

Therefore, the probability that the average temperature for a sample of 130 healthy people is 98.25 degrees or higher is approximately 0.9719 or 97.19%.

Answer: I think it might be A.

Step-by-step explanation:

Answer:

Since line segment PQ is the result of reflecting line segment AB across the x-axis, we know that the y-coordinates of corresponding points on AB and PQ are the same but have opposite signs.

So if P has coordinates (2,-2) on PQ, then its corresponding point on AB must have coordinates (2, 2). Similarly, if Q has coordinates (8,-2) on PQ, then its corresponding point on AB must have coordinates (8, 2).

Therefore, the length of line segment AB is the distance between points (2, 2) and (8, 2) on the coordinate plane, which is:

AB = |8 - 2| = 6

So the answer is B) 6

The probability that a randomly selected gas station customer on that day did not purchase gasoline is 10/27.

We know that, the probability of any event is the ratio of the number of favorable case to that event to the total number of cases.

The total number of customers in that Gas Station on that day = 135

According to the data table,

Number of customers did not purchase gas but purchased beverage = 35

Number of customers neither purchase gas nor beverage = 15

So total number of customers did not purchase gas = 35 + 15 = 50

Here number of favorable cases = 50

So the probability that a randomly selected gas station customer on that day did not purchase gasoline = 50/135 = 10/27.
