The answer is c because 86,700,000 minus 34,500,000 = 52,200,000 and the only one that multiplys out to 52,200,000 is c
Answer:
you will need 100 feet of rope
Step-by-step explanation:
the current dimensions are 25 ft wide by 20 ft long, and they want it to have a width of 30 ft so the length is the same but the width canges by 5 so
20 times 5 = 100
hope this helps ;)
Answer:
48+x
Step-by-step explanation:
56-2(4+x)
56-8+x
48+x
Answer: 3x + 5 = 57.50
Step-by-step explanation:
Assume that the price of one video game is x. Jamie bought 3 video games so the expression will be:
= 3x
His sister talked him into buying two $1.50 candy bars and a $2.00 drink. The total of this is:
= 1.50 + 1.50 + 2.00
= $5.00
The total amount spent on both the video game and the snacks is $57.50. Equation will therefore be:
3x + 5 = 57.50
Answer:
d) Squared differences between actual and predicted Y values.
Step-by-step explanation:
Regression is called "least squares" regression line. The line takes the form = a + b*X where a and b are both constants. Value of Y and X is specific value of independent variable.Such formula could be used to generate values of given value X.
For example,
suppose a = 10 and b = 7. If X is 10, then predicted value for Y of 45 (from 10 + 5*7). It turns out that with any two variables X and Y. In other words, there exists one formula that will produce the best, or most accurate predictions for Y given X. Any other equation would not fit as well and would predict Y with more error. That equation is called the least squares regression equation.
It minimize the squared difference between actual and predicted value.
