<span><u><em>Answer:</em></u>
Dave makes $350
<u><em>Explanation:</em></u>
In order to find this answer, we must first establish the equation for his earnings.
<u>We use slope intercept form:</u>
y = mx + b,
where m = slope and b = y-intercept.
Since the problem states that his commission percentage is the slope and his base salary is the y-intercept, we can use them in the equation <u>to get the following: </u>
y = 0.1x + 200.
Now knowing that the x is the amount he sells, we can use the $1500 as x to find his total pay for the week:.
y = 0.1(1500) + 200,
y = 150 + 200,
y = 350. </span>
The dot product will have you multiply the corresponding coordinates and add up the products
v dot w = (6*(-7)) + (7*5) + (-3*2)
v dot w = -42 + 35 - 6
v dot w = -7 - 6
v dot w = -13
Answer: -13
(b) one-sample t-test for a population mean
ur welcome :D
The hard part is just making sense of what they are asking for.
4 times the quantity of a number decreased by one is just the expression:
4 * (x-1)
Where "x" is our mystery number.
Two more than the same number is just:
x + 2
Where "x" is our same mystery number.
They say that these two expressions are the same, so just set them equal to each other.
4*(x-1) = x+2
4x - 4 = x +2
3x -4 = 2
3x = 6
x = 2
The mystery number is 2. Plug in 2 and you will see that it works!
6000000 just add 6 zeros at the end
