Answer:

50

Step-by-step explanation:

bfa and afe will add up to equal 180 because they are supplementary

20x+2x+70=180

22x+70=180

22x=110

x=5

then you plug in 5 to 2x+70 to get 80

cfe and afe are also complementary so they will add up to equal 180 so angle cfe equals 100

cfd and cfe are the same angles so 100/2=50.

the arc length is the same as the angles so arc length dc is 50

Step-by-step explanation:

Therefore, Caleb paid approximately $14,067.90 for the shares.

Let's assume the amount Caleb paid for the shares is represented by the variable "x". According to the given information, his selling price was 130% of the amount he paid.

Selling price = 130% of the amount paid

$18,189.27 = 1.3 * x

To find the amount he paid for the shares, we can solve the equation for "x" by dividing both sides by 1.3:

x = $18,189.27 / 1.3

Calculating this, we find:

x ≈ $14,067.90

There is a 21.5% chance that the stock's price will exceed $105 after 10 days.

Given that the daily change of price of the company's stock has a mean of 0 and variance of 1 (σ2=1), we know that the standard deviation is σ=1. Using the formula for the mean and variance of the sum of independent random variables, we can find that the mean of the stock's price after 10 days is 0 and the variance is 10σ2=10.

To find the probability that the stock's price will exceed $105 after 10 days, we need to calculate the probability of the standardized variable being greater than (105-100)/σ√10, where σ√10 is the standard deviation of the sum of the 10 independent random variables.

Thus, the probability that the stock's price will exceed $105 after 10 days is the same as the probability that a standard normal variable Z is greater than 0.79 (=(105-100)/1√10). Using a standard normal distribution table or a calculator, we find that this probability is approximately 0.215, or 21.5%.

Therefore, we can say that there is a 21.5% chance that the stock's price will exceed $105 after 10 days.

The probability that a randomly selected number, among the positive integers less than 100100, whose digits are all prime numbers, is also prime is 17/1024 or approximately 0.0166.

To find the probability that a randomly selected number, among the positive integers less than 100100, whose digits are all prime numbers, is also prime, we need to determine the count of prime numbers meeting this criteria and divide it by the total count of numbers meeting the given criteria.

First, let's identify the prime digits: 2, 3, 5, and 7.

Now, we can construct the eligible numbers by considering the positions in the number. The leftmost digit can be any of the prime digits (2, 3, 5, or 7), while the remaining four digits can be any of the prime digits (2, 3, 5, or 7) as well.

Therefore, the total count of eligible numbers is 4 × 4 × 4 × 4 × 4 = 1024.

Next, we need to determine the count of prime numbers among these eligible numbers. We can check each number individually to see if it is prime.

Upon inspection, we find that the eligible numbers which are prime are: 2, 3, 5, 7, 23, 25, 27, 32, 35, 37, 52, 53, 57, 72, 73, 75, 77.

The count of these prime numbers is 17. Therefore, the probability that the selected number is prime is 17/1024, which can be simplified, if desired.

Answer:

All possible values of ∠Y are 76.6° and 103.4°

Step-by-step explanation:

In Δ WXY

∵ x is the opposite side of ∠X

∵ y is the opposite side of ∠Y

→ By using the sine rule

∴ \(\frac{x}{sin(X)}\) = \(\frac{y}{sin(Y)}\)

∵ x = 85 and y = 88

∴ m∠X = 70°

→ Substitute them in the rule above

∴ \(\frac{85}{sin(70)}\) = \(\frac{88}{sin(Y)}\)

→ By using the cross multiplication

∴ 85 × sin(Y) = 88 × sin(70)

→ Divide both sides by 85

∴ sin(Y) = 0.9728582427

∴ m∠Y = \(sin^{-1}\)(0.9728582427)

∴ m∠Y = 76.62037845

→ Round it to the nearest tenth

∴ m∠Y = 76.6°

→ The other value of ∠Y is the obtuse angle supplement of ∠Y

∴ m∠Y = 180 - 76.6

∴ m∠Y = 103.4°

∴ All possible values of ∠Y are 76.6° and 103.4°

Step-by-step explanation:

Because say you got 1 right out of 5 on test you get a 20%

since 20 can go into a 100 5 times if whatever number is the 1rst time it can go into 5 it is a 20 like 4:20 because 4,8,12,16,20 see that's 5 numbers and 4 is the first.

In then 1:5 is another example it can go 5 times or one more is like 10:50=20% or 15:75.

To convert watts to horsepower, use the formula 1Hp = 735Watt.

Watt and horsepower are both power units.

Nevertheless, horsepower is a more potent unit of power. We measure the power of electrical instruments such as turbines, motors, and a variety of other devices using horsepower.

Hence, 1 Horsepower is 735 Watt using standard unit conversion rates.

1 Hp = 735 W

As a result, we have the conventional relationship 1Hp = 735 W. We can now simply convert any horsepower provided to the unit of Watt.

y = 2x + 2

Step-by-step explanation:

Firstly find the gradient of the line using the formula;

⇒ \(m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\)

⇒ \(m = \frac{8 - 2}{3 - 0}\)

⇒ \(m = 2\)

Now substitute into the formula to find the equation of a straight line;

⇒ \(y - y_{1} = m(x - x_{1})\)

⇒ \(y - 2 = 2(x - 0)\)

⇒ \(y = 2x + 2\)

if the equation is y+=1/2 (x-3) the slope is wrong.  the slope is actually 6. that was the error that Sydney made. i hope this help some of my people out:)

Multicollinearity is used to describe the problem of using variables that strongly correlate with one another in a multiple linear regression model.

Multiple linear regression refers to a statistical technique that is used to predict the outcome of a variable based on the value of two or more variables. It is sometimes known simply as multiple regression, and it is an extension of linear regression. The variable that we want to predict is known as the dependent variable, while the variables we use to predict the value of the dependent variable are known as independent or explanatory variables.

Multicollinearity, also known as collinearity, is a phenomena in statistics when one predictor variable in a multiple regression model can be linearly predicted from the others with a high level of accuracy. In this case, minor adjustments to the model or the data may cause the multiple regression's coefficient estimates to fluctuate unpredictably. Multicollinearity only impacts calculations pertaining to specific predictors; it has no impact on the predictive capability or reliability of the model as a whole, at least within the sample data set. In other words, a multivariate regression model with collinear predictors can show how well the entire set of predictors predicts the outcome variable, but it might not provide accurate information about any particular predictor or about which predictors are redundant with respect to another predictor.
