Answer:

Slope- intercept form       y = 200 x + 500

Step-by-step explanation:

Explanation:-

Given that the equation

        200x - y + 500 = 0

where   y, the number of pairs of skates the factory has in the warehouse, and x be the number of hours

The slope-intercept form

                 y = m x +C

Given equation  200x - y + 500 = 0

                           200 x + 500 =y

                        y = 200 x + 500

Slope of the equation m = 200 and y-intercept 'C' = 500

The Wald test is a statistical test that can be used to test the significance of a group of coefficients in a multiple regression model.

The test statistic is calculated as the ratio of the estimated coefficient to its standard error. If the test statistic is significant, then the null hypothesis that the coefficient is equal to zero can be rejected.

Suppose we have a multiple regression model with three independent variables: age, gender, and education. We want to test the hypothesis that the coefficients for age and education are both equal to zero. The Wald test statistic would be calculated as follows:

Test statistic = (Estimated coefficient for age) / (Standard error of estimated coefficient for age) + (Estimated coefficient for education) / (Standard error of estimated coefficient for education)

If the test statistic is significant, then we can reject the null hypothesis that the coefficients for age and education are both equal to zero. This would mean that there is evidence that age and education are both associated with the dependent variable.

The Wald test is a powerful tool that can be used to test the significance of a group of coefficients in a multiple regression model. However, it is important to note that the test statistic is only valid if the assumptions of the multiple regression model are met. If the assumptions are not met, then the p-value of the Wald test may be inaccurate.

Here are some of the assumptions of the multiple regression model:

* The independent variables are independent of each other.

* The dependent variable is normally distributed.

* The errors are normally distributed.

* The errors have constant variance.

If any of these assumptions are not met, then the Wald test may not be accurate.

In the given scenario ladder is 6.52 feet long.

Given that,

The angle between ground and ladder = 62 degree

The distance of ladder from ground and ladder = 3 feet

We have to find the length of  ladder.

Since we know that,

The trigonometric ratio

cosθ = adjacent/ Hypotenuse

Here we have,

Adjacent =  3 feet

Hypotenuse = length of ladder

Thus to find the length of ladder we have to find the value of hypotenuse.

Therefore,

⇒ cos62 = 3/ Hypotenuse

⇒    0.46 = 3/ Hypotenuse

⇒ Hypotenuse =  3/0.46

                          = 6.52

Thus,

length of ladder  = 6.52 feet.

Outcomes of rolling an even number are 2, 4, and 6. Outcomes of flipping a tail are T.

So, the probability of rolling an even number or flipping a tail is the sum of the probabilities of rolling an even number and flipping a tail, minus the probability of rolling an even number and flipping a tail (because this outcome is counted twice):

P(even or tail) = P(even) + P(tail) - P(even and tail)

P(even) = 3/6 (since there are three even numbers out of six possible outcomes)

P(tail) = 1/2 (since there is one tail out of two possible outcomes)

P(even and tail) = 1/6 (since only the outcome of rolling a 2 and flipping a tail satisfies both conditions)

Therefore,

P(even or tail) = 3/6 + 1/2 - 1/6 = 7/12

So, the probability of rolling an even number or flipping a tail is 7/12.

because  4(x + 1) = 4x + 4 for all value of x

Step-by-step explanation:

There are 11 letters in the word mathematics. The probability of selecting the letter "e" first is 1/11, which is approximately 0.091 in decimal form when rounded to the nearest thousandth.

This is because there is only one "e" in the word mathematics, and we are selecting one letter out of the 11 total letters.

To find the probability that the first letter is "e" in the word "mathematics," follow these steps:

1. Count the total number of letters in the word: There are 11 letters in "mathematics."

2. Count the occurrences of the letter "e": There is 1 "e" in "mathematics."

3. Calculate the probability: Divide the occurrences of "e" by the total number of letters.

Probability = (Occurrences of "e") / (Total number of letters) = 1 / 11

In decimal form and rounded to the nearest thousandth, the probability that the first letter is "e" in the word "mathematics" when arranged randomly is approximately 0.091.

The distance between the two comets in kilometers (km) is 9 × 10^9 km.

Astronomers measure distances in astronomical units (AU). One AU is approximately equal to 1.5× 10^(8) km. The distance between two comets is 60AU.

Using these values, let's determine the distance between the two comets in kilometers (km).The distance between two comets is 60AU.1AU is equal to 1.5× 10^(8) km.

Therefore, the distance between the two comets in kilometers (km) is 60 * 1.5 × 10^8 km. The above expression simplifies as follows:

                 60 × 1.5 × 10^8 km = 9 × 10^9 km.

The probability of the soft drink machine filling a cup between 2121 and 3030 ounces with a normal distribution of the mean of 2727 ounces and a standard deviation of 33 ounces is 0.

It is given that the soft drink machine's output is normally distributed.

We know that for any normal distribution with X~(μ,σ)

f(z)= 1/σ√2π . e^(-(x - μ)²/2σ²),for all z ∈ R.

where  μ = The mean of the distribution

σ = the standard deviation of the distribution

Here

μ = 2727

σ = 33

We need to find

P(2121< x < 3030)

We know that the relation between a normal distribution and its Z-score is

P(a < X < b) = Φ((b- μ)/ σ)  -  Φ(a - μ/ σ)

here a = 2121  and  b = 3030

Therefore we get

P(2121< x < 3030) = Φ((3030- 2727)/ 33)  -  Φ(2121 - 2727/ 33)

= Φ((303)/ 33)  -  Φ(-606/ 33)

= Φ((303)/ 33)  -  Φ(-606/ 33)

= Φ((9.181818)  -  Φ(-18.363636)

The expected result of the expression w = (x - y) * w * z, calculated using the floating point system F(10, 5, -5, 4), can be approximated as -0.18950 × 10⁴. This aligns with option a) -0.18950 × 10⁴.

To determine the likely outcome of the expression w = (x - y) * w * z using the given floating-point system F(10, 5, -5, 4), let's perform the calculations step by step:

1. x = 11/7:

  - The number 11/7 cannot be exactly represented in the given floating-point system since it requires more than 5 fractional bits.

  - We need to approximate 11/7 to fit within the range and precision of the system.

  - Assuming rounding to the nearest representable number, we get x ≈ 1.5714.

2. y = 1.5719:

  - The number 1.5719 can be represented in the given floating-point system.

  - No approximation is needed.

3. w = 1000:

  - The number 1000 can be represented in the given floating-point system.

  - No approximation is needed.

4. z = 379:

  - The number 379 can be represented in the given floating-point system.

  - No approximation is needed.

Now, let's perform the calculation step by step:

Step 1: (x - y)

  - Performing the subtraction: 1.5714 - 1.5719 ≈ -0.0005

  - The result of this subtraction is -0.0005.

Step 2: (x - y) * w

  - Multiplying the result from Step 1 (-0.0005) by w (1000):

    -0.0005 * 1000 = -0.5

  - The result of this multiplication is -0.5.

Step 3: (x - y) * w * z

  - Multiplying the result from Step 2 (-0.5) by z (379):

    -0.5 * 379 = -189.5

  - The final result of the expression is -189.5.

Therefore, the likely outcome of w = (x - y) * w * z using the given floating-point system F(10, 5, -5, 4) is -0.18950 × 10⁴, which corresponds to option a) -0.18950 × 10⁴.
