Answer:
The average goes up by 0.6.
Step-by-step explanation:
The average of the original data set, 6,6,7,8,9 is 7.2. The average of the new data set with 3 more cookbooks 6,7,8,9,9 is 7.8. Therefore it increases by 0.6, hope that makes sense :)
-7x + y = -6 |add 7x to both sides
y = 7x - 6
the slope: m = 7
the y-intercept: y = -6
Step-by-step explanation:
Calculate and compare the z scores.
z = (x − μ) / σ
For the male:
z = (1700 − 3277.9) / 571.6
z = -2.76
For the female:
z = (1700 − 3091.6) / 625.7
z = -2.22
The absolute value of the male z score is greater than the absolute value of the female z score. Therefore, the male newborn's weight is more extreme.
In this question, you're solving by adding the two expressions together.
(f+g)(x) is the same as:
3x - 1 + x + 2
Solve:
3x - 1 + x + 2
<em>combine like terms:</em>
4x - 1 + 2
4x + 1
Answer:
4x + 1
Dv/dt=40 dv/dt=3x^2dx/dt
40=3x^2dx/dt
40=12dx/dt
10/3=dx/dt
