The regression equation below relates the scores students in
an advanced statistics course received for homework completed and the
subsequent midterm exam. Homework scores are based on assignments that preceded
the exam. The maximum homework score a student could obtain was 500 and the
maximum midterm score was 350. The regression line that was obtained is given
by
y=-84.4 + .91x
if the homework score is 420, substitute it to the x of the
equation and solve for y to get the midterm score
y= 298
Answer:
The amount of money in the account after t years is given by:
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Invested $5000 at 6% per year and is compounded quarterly
This means, respectively, that
So, the amount of money in the account after t years will be given by:
Answer:
4/7
Step-by-step explanation:
32:56
Divide each number by 8
32/8: 56/8
4:7
Writing them as numerator and denominator
4/7

Answer: Choice A. |w - q|</h3>
Let's say for example that w = 10 and q = 7. This means the distance between these values is w-q = 10-7 = 3. This is the distance between w and q.
Now let's make q larger. If w = 12 and q = 20, then w-q = 12-20 = -8 assuming we subtract in the same order. We use absolute value bars to ensure the result is positive. So instead we say
|w - q| = |12 - 20| = | -8 | = 8
Distance is never negative.
90° is equal to or 1.5707 radians.
Step-by-step explanation:
Step 1:
If an angle is represented in degrees, it will be of the form x°.
If an angle is represented in radians, it will be of the form radians.
To convert degrees to radians, we multiply the degree measure by .
For the conversion of degrees to radians,
the degrees in radians = (given value in degrees)().
Step 2:
To convert
90°,
radians.
So 90° is equal to or 1.5707 radians.
