Answer true or false. If​ false, explain briefly. ​a) Some of the residuals from a least squares linear model will be positive a

nd some will be negative. ​b) Least squares means that some of the squares of the residuals are minimized. ​c) We write ModifyingAbove y with caret to denote the predicted values and y to denote the observed values.

marta [7]

Answer:

2.20752 x 10^{24}

Step-by-step explanation:

The first thing you have to do is to look for the number of seconds in one year. You have to multiply 365 days by 86,400 seconds.

  • 365 days refer to the total number of days per year
  • 86,400 seconds refer to the number of seconds per day

Let's solve.

  • 365 x 86,400 = 31,536,000 or 3.1536 x 10^{7}

<em>Therefore, one year has 3.1536 x </em>10^{7}<em> seconds.</em>

Next, you have to know the number of seconds in 10 billion years.

  • (3.1536 x 10^{7}) x  (1.0 x 10^{10}) = 3.1536 x 10^{17}

The last step is to multiply the number of seconds in 10 billion years to 7 million tons of mass per second.

  • (3.1536 x 10^{17}) x 7,000,000 = 2.20752 x 10^{24}

Monte carlo simulation generates many outcomes that are organized into a frequency distribution.
nalin [4]

The statement is True, Monte Carlo simulation generate many outcomes that are organized into a frequency distribution.

Monte Carlo simulation

  • When the possibility of random variables is available, a Monte Carlo simulation is a model that is used to forecast the likelihood of a variety of events. Monte Carlo simulations assist in illuminating how risk and uncertainty affect forecasting and prediction models

  • The potential accuracy of a Monte Carlo simulation is roughly 4%, which is still higher than the 1% accuracy stated by SAMPLE, even for a random function with a 3 error factor.

Shania drove on the interstate for 310 miles without stopping. If she traveled at a constant rate and the trip took her 5 hours,
sp2606 [1]

Answer:

62 miles per hour/62 mph

Step-by-step explanation:

Shania drives at a CONSTANT rate, which means in the 5 hours it took her to drive, each hour she drove the same amount.

So we need to do 310 miles in 5 hours, which is:

310/5

Solving this, we get:

62

The answer is 62 miles per hour.

Happy learning!
