The measure of the angle ADB, obtained from the relationship between the base angles of an isosceles triangle and the angle formed at the center and on the circumference of circle is; ∠ADB = 55°

An isosceles triangle is a triangle that has congruent base angles.

The angle at the m∠A = 180°- (30° + 70°) = 80°

The two tangent and secant theorem indicates that the half the difference between the arcs CD and AB is; 30°, therefore;

30 = (1/2) × (AB - CD)

The congruence relationship between the segment BC and AB indicates that the base angle of the isosceles triangle ABC and the angle ACB

Therefore, the angle ACB = 55°

The angle at the center a of a circle is twice the angle formed at the circumference of a circle.

Arc AB = 2 × angle ACB = 2 × 55° = 110°

Arc CD = 110 - 2 × 30 = 50°

∠DBC = 50°/2 = 25°

∠DBA = 70° - 25° = 45°

Angle ADB = 180 - 80 - 45 = 55

Angle ADB = 55°

Answer:

(a) 2.22

(b) 1.3986

(c) 1.183

Step-by-step explanation:

Let X denote the number of women who consider themselves fans of professional baseball.

The proportion of women who consider themselves fans of professional baseball is, p = 0.37.

A random sample of n = 6 women are selected and each was asked if she considers herself a fan of professional baseball.

Each woman's reply is independent of the others.

The random variable X thus follows a binomial distribution with parameters n = 6 and p = 0.37.

(a)

Compute the mean of the binomial distribution as follows:

\(\text{Mean}=np=6\times 0.37=2.22\)

(b)

Compute the variance of the binomial distribution as follows:

\(\text{Variance}=np(1-p)=6\times 0.37\times (1-0.37)=1.3986\)

(c)

Compute the standard deviation of the binomial distribution as follows:

\(\text{Standard Deviation}=\sqrt{np(1-p)}=\sqrt{6\times 0.37\times (1-0.37)}=1.183\)

x-.20x

Lets say the hat cost $100

x=100

multiplying 100 by 20% which is .20 yields $20

S0 $20 is the discount which we subtract from the original price

100-20 and get the sale price of $80

They use a shortcut so you don't have to do the subtracting of the discount

They say if the price is being discounted subtract the discount from 1 and multiply that by the original amount

So in this case the discount percent was 20% = .20

Subtracted from 1

1-.20=.80

Since x is the original price we multiply x by the .80 to get

Answer:

Antarctica's highest recorded temperature was 15 degrees.

Step-by-step explanation:

I am going to say that Antarctica highest recorded temperature is x.

I suppose there is a small typing mistake.

It is that the difference between Antarctica highest recorded temperature and this is 49.44.

So we have that x - (-34.44) = 49.44 instead of -34.44 - x = 49.44, which would lead to a highest temperature way lower than the one recorded in this winter.

So

x - (-34.44) = 49.44

x + 34.44 = 49.44

x = 49.44 - 34.44

x = 15

Antarctica's highest recorded temperature was 15 degrees.

Answer:

15 degrees

Step-by-step explanation:

According to the given statement the total number of ordered pairs is: (2 - 1) * (3 - 1) * (5 - 1) * (7 - 1) * ... * (97 - 1) = 1 * 2 * 4 * 6 * ... * 96 = 2⁴⁹ * 3²⁴* 5⁹* 7⁴ * ... * 97 .

To find the number of ordered pairs (x, y) where both xy and x1y1 are integers, we need to consider the prime factorization of the given expressions.

Let's first analyze xy.

For xy to be an integer, x and y must have a common factor.

Since y < x and x ≤ 100, we can consider all the prime numbers up to 100.

There are 25 prime numbers up to 100.

For each prime number p, we need to find the number of values of y that are less than x and have p as a factor.

For a given prime p, the number of such values of y is equal to p - 1.

So, the total number of values of y for each prime p is (p - 1).

Now, let's consider x1y1. Similar to the previous case, we consider all the prime numbers up to 100.

For each prime p, the number of values of y1 that are less than x1 and have p as a factor is again (p - 1).

Since x and y are positive integers, the total number of ordered pairs (x, y) where both xy and x1y1 are integers is the product of the number of values of y and y1 for each prime p.

The total number of ordered pairs (x, y) is equal to 2⁴⁹ * 3²⁴ * 5⁹ * 7⁴ * ... * 97.

The mean of all the possible sample means is equal to the population mean, ensuring that the sample mean is an unbiased estimator.

Therefore, option a is correct.

The sample mean is an unbiased estimator of the population mean because, on average, it equals the true population mean.

This means that if we were to repeatedly take random samples from the population and calculate the mean of each sample, the average of all those sample means would converge to the population mean.

The concept of unbiasedness in estimation refers to the absence of systematic errors or biases in the estimation process.

In this case, the sample mean provides an unbiased estimate of the population mean because it does not consistently overestimate or underestimate the true population mean.

When we take multiple samples from a population, each sample may yield a slightly different mean due to random sampling variability. However, the average of all those sample means will approach the population mean, regardless of whether individual sample means are higher or lower than the population mean.

The correct answer is:

a. The mean of all the possible sample means is equal to the population mean.

 no  solution  for  it

Answer:

No solution

Step-by-step explanation:

We want to solve the system of equations:

\(2y = 4x + 12\)

\(y = 2x + 4\)

To do this, substitute the value of y in the second equation into the first equation:

➡️ 2(-2x + 4) = -4 + 12

-4x + 8 = -4x + 12

Collect like terms:

\( - 4x + 4x = 12 - 8\)

\(0 = 4\)

As we can see, we have that 0 is equal to 4.

This shows that the system of equations has no solution.

The key to this problem is to write out the probabilities and determine which one is most likely and least likely (or impossible).

Drawing a black card from a standard deck of playing cards:

There are 52 cards in a playing deck, 26 are red and 26 are black.

\(\frac{26}{52}\) = \(\frac{1}{2}\)

A spinner has 5 equal sections numbered 1 through 5. You spin and land on a number less than or equal to 4.

This means that all the numbers (1, 2, 3, and 4) except 5.

\(\frac{4}{5}\)

You roll a standard number cube and get a number less than 2.

A standard cube is from 1 to 6, and 1 is the only number on the cube that is less than 2.

\(\frac{1}{6}\)

You roll two standard number cubes and the sum is 1.

The smallest number on a standard cube is 1, so you can't make the sum 1 with 2 dice.

0

If we put these in order, we get:

Answer: The sprinkler can cover is 450 square feet.

Step-by-step explanation: The area covered by a circle is given by the formula:

A = πr^2

where A is the area and r is the radius.

In this case, the radius is given as 12 feet, so we can calculate the area covered by the sprinkler as:

A = π(12 ft)^2

A = 144π square feet

We can use the approximation π ≈ 3.14 to estimate the area covered:

A ≈ 144 x 3.14

A ≈ 452.16 square feet

Therefore, the closest choice to the area of lawn that the sprinkler can cover is 450 square feet.

Using the P-value method of testing hypotheses with a significance level of 0.05, the sample provides strong evidence to support the claim that the mean score of job applicants from the university is greater than 160.

To test the claim that the mean score of job applicants from the university is greater than 160, we will perform a one-sample t-test using the P-value method. The null hypothesis (H0) assumes that the mean score is equal to 160, while the alternative hypothesis (Ha) assumes that the mean score is greater than 160.

First, we calculate the test statistic, which is the t-value. The formula for the t-value is:

t = (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size))

Plugging in the given values, we have:

t = (183 - 160) / (12 /   √(25))

  = 23 / (12 / 5)

  = 23 * (5 / 12)

  ≈ 9.58

Next, we find the P-value associated with the test statistic. The P-value represents the probability of obtaining a test statistic as extreme as the observed value, assuming the null hypothesis is true. Since the alternative hypothesis is one-sided (greater than 160), we calculate the P-value by finding the probability of the t-distribution with 24 degrees of freedom being greater than the calculated t-value.

Consulting statistical tables or using software, we find that the P-value is very small (less than 0.0001).

Since the P-value (less than 0.0001) is less than the significance level (0.05), we reject the null hypothesis. This provides strong evidence to support the claim that the mean score of job applicants from the university is greater than 160.
