i got 10.5 need help pls

Answer:

D

Step-by-step explanation:

The first number in each co-ordinate is the same so -1 plus 4 is 5 units

Answer:

5 units

Step-by-step explanation:

The x-coordinates of both coordinates are the same, so you only need to add the absolute values of -1 and 4, which is 5.

Answer:

2 1/6

Step-by-step explanation:

The answer is 2 1/6 because you should start by adding 3 1/2 + 2 1/3. This equals 5 5/6 feet. You should then subtract 8 - 5 5/6 because you are figuring out how much is left. When you subtract 8 - 5 5/6, you get 2 1/6. So 2 1/6 feet of the board is left.

Based on the given temperature data, the forecasted high temperature for today using a three-day moving average is 93°F, and using a two-day moving average is 89°F. The mean absolute deviation for the two-day moving average is 1°F, and the mean squared error is 1. The mean absolute percent error for the two-day moving average is approximately 1.13%.

These metrics provide a way to assess the accuracy of the temperature forecasts and the variability of the actual temperatures from the moving averages.

a) To forecast the high temperature today using a three-day moving average, we take the average of the temperatures from the last three days. So, (95 + 96 + 88) / 3 = 93°F.

b) To forecast the high temperature today using a two-day moving average, we take the average of the temperatures from the last two days. So, (88 + 90) / 2 = 89°F.

c) The mean absolute deviation (MAD) based on a two-day moving average is calculated by finding the absolute difference between each temperature and the two-day moving average, summing up those differences, and then dividing by the number of observations.

The two-day moving average is 89°F. The deviations from the moving average are: |88 - 89| = 1 and |90 - 89| = 1. The sum of these deviations is 1 + 1 = 2. Since we have two observations, the MAD is 2 / 2 = 1°F.

d) The mean squared error (MSE) for the two-day moving average is calculated by squaring the differences between each temperature and the two-day moving average, summing up those squared differences, and then dividing by the number of observations.

The differences are: (88 - 89)^2 = 1 and (90 - 89)^2 = 1. The sum of squared differences is 1 + 1 = 2. Since we have two observations, the MSE is 2 / 2 = 1.

e) The mean absolute percent error (MAPE) for the two-day moving average is calculated by finding the absolute difference between each temperature and the two-day moving average, dividing that difference by the actual temperature, summing up those absolute differences, and then dividing by the number of observations.

The two-day moving average is 89°F. The absolute percent differences are: |88 - 89| / 88 = 0.0114 and |90 - 89| / 90 = 0.0111. The sum of these absolute differences is 0.0114 + 0.0111 ≈ 0.0225. Since we have two observations, the MAPE is 0.0225 / 2 ≈ 0.0113 or 1.13%.

Answer:

250 miles

Step-by-step explanation:

The given distance between the house and the beach is 125 miles.

Let \(x\) miles be the distance between the house and the lunch stop.

So, at the time of the lunch stop, he already traveled \(x\) miles, the remaining distance is the distance between the lunch stop and the beach.

Let \(y\) miles be the remaining distance, so

\(y=125-x.\)

Give that the ratio of the distance he has traveled, \(x\), to the distance he still has to travel, \(y\), is \(2:3\),i.e

\(x:y=2:3\)

\(\Rightarrow \frac x y =\frac 2 3\)

\(\Rightarrow \frac {x}{125-x}=\frac 2 3\)

\(\Rightarrow 3\times x=2\times(125-x)\)

\(\Rightarrow 3\times x=2\times125-2\timesx\)

\(\Rightarrow 3 x=250-2x\)

\(\Rightarrow 3x-2x=250\)

\(\Rightarrow x=250\)

Hence, the distance traveled by Herman when he stops for lunch is 250 miles.

Answer:

5(8x + 6y), 10(4x + 3y), 2(20x + 15y)

Step-by-step explanation:

(5x *8) + (5x *6) = 40x + 30x no

(5 * 8x) + (5 *6y) = 40x + 30y yes

10*40x + 10*30y = 400x + 300y no

10*4x + 10*3y = 40x + 30y yes

2y *20x + 2y*15 = 40xy + 30y no

2*20x + 2*15y = 40x + 30y yes

The expressions that are equivalent to (40x + 30y) is (10(4x + 3y)) and (2(20x + 15y)) and this can be determined by using the arithmetic operations.

Given :

Expression  --  (40x + 30y)

Answer:

The second one

Step-by-step explanation:

(1) Using the Black/Scholes Option Pricing Model, the value of the call option is $7.70.

(2) The intrinsic value of the call is the difference between the stock price and the strike price of the option. Therefore, it is $4.

(3) The stock price required to break-even is the sum of the strike price and the option premium. Therefore, it is $74.

(4) If volatility were to decrease, the value of the call would decrease.

(5) If the exercise price would increase, the value of the call would decrease.

(6) If the time to maturity were 3-months, the value of the call would decrease.

(7) If the stock price were $62, the value of the call would be zero.

(8) The maximum value that a call option can take is unlimited.

In the Black/Scholes option pricing model, the value of a call option can be calculated using the formula:

C = S*N(d1) - X*e^(-rT)*N(d2)

where S is the stock price, X is the exercise price, r is the risk-free rate, T is the time to maturity, and σ2 is the variance of the stock's return.

Using the given values, we can calculate d1 and d2:

d1 = [ln(S/X) + (r + σ2/2)T]/(σ2T^(1/2))

   = [ln(74/70) + (0.10 + 0.50/2)*0.5]/(0.50*0.5^(1/2))

   = 0.9827

d2 = d1 - σ2T^(1/2) = 0.7327

Using these values, we can calculate the value of the call option:

C = S*N(d1) - X*e^(-rT)*N(d2)

= 74*N(0.9827) - 70*e^(-0.10*0.5)*N(0.7327)

= $7.70

The intrinsic value of the call is the difference between the stock price and the strike price of the option. Therefore, it is $4.

The stock price required to break-even is the sum of the strike price and the option premium. Therefore, it is $74.If volatility were to decrease, the value of the call would decrease. This is because the option's value is directly proportional to the volatility of the stock.

If the exercise price would increase, the value of the call would decrease. This is because the option's value is inversely proportional to the exercise price of the option.

If the time to maturity were 3-months, the value of the call would decrease. This is because the option's value is inversely proportional to the time to maturity of the option.If the stock price were $62, the value of the call would be zero. This is because the intrinsic value of the call is zero when the stock price is less than the strike price.

The maximum value that a call option can take is unlimited. This is because the value of a call option is directly proportional to the stock price. As the stock price increases, the value of the call option also increases.

Step-by-step explanation:

Answer:

yeah i think its B too

Step-by-step explanation:

the absolute difference between two consecutive terms of this arithmetic sequence is 18.

Let's denote the first term of the arithmetic sequence as 'a' and the common difference as 'd'.

The sum of the first five terms can be expressed as:

S1 = a + (a + d) + (a + 2d) + (a + 3d) + (a + 4d)

The sum of the next five terms can be expressed as:

S2 = (a + 5d) + (a + 6d) + (a + 7d) + (a + 8d) + (a + 9d)

According to the given information, the sum of the first five terms is 90 less than the sum of the next five terms:

S1 = S2 - 90

Substituting the expressions for S1 and S2:

a + (a + d) + (a + 2d) + (a + 3d) + (a + 4d) = (a + 5d) + (a + 6d) + (a + 7d) + (a + 8d) + (a + 9d) - 90

Simplifying the equation:

5a + 10d = 5a + 15d - 90

Canceling out the common terms:

10d = 15d - 90

Rearranging the equation:

5d = 90

Dividing both sides by 5:

d = 18

Now that we have the common difference 'd', we can find the absolute difference between two consecutive terms by subtracting one term from the next. In this case, the absolute difference is equal to the common difference 'd':

Absolute difference between two consecutive terms = d = 18

f(5) = 0, If f(x) = 8, then x = 1, f⁻¹(0) = 5, If f⁻¹(x) = 1, then x = 3. By looking at the given table, we can determine the missing values:

f(5) corresponds to the value of f(x) when x = 5, which is 0.
If f(x) = 8, we need to find the corresponding value of x. From the table, we can see that x = 1 when f(x) = 8.
f⁻¹(0) represents the inverse of the function f(x) = 0. By examining the table, we find that f⁻¹(0) corresponds to x = 5.
If f⁻¹(x) = 1, we need to find the value of x. From the table, we can see that x = 3 when f(x) = 1.
