Number of scores n = 7
Mean of the total scores, m = 10
One value is given that is x = 4.
Calculating the total T = m x n = 10 x 7 = 70
Total without the given value = 70 - 4 = 66
Mean of the remaining scores would be 66 / 6 = 11.
Answer:

Step-by-step explanation:
The equation for the plant's height after t weeks has the following format:

In which h(0) is the initial height and r is the rate it increases per week, as a decimal.
Spencer plants a 7-inch tomato plant in his garden.
This means that 
The plant grows by about 15% per week for several months.
This means that
. So



Answer:
When x ⇒ +∞ and x ⇒ -∞, f(x) ⇒ 0 from the positive region.
Step-by-step explanation:
Hi there!
Let´s write the function:
f(x) = (7x³ + 2) / (4x⁵ - 3x + 1)
When x ⇒ +∞ we can neglect the constant values (2 and 1). So:
f(x) ⇒ 7x³ /(4x⁵ - 3x)
f(x) ⇒ 7x³ / x(4x⁴ - 3)
f(x) ⇒ 7x² / 4x⁴
f(x) ⇒ 7/4x² ⇒ 0 from the positive region
when x ⇒ -∞
f(x) ⇒ 7/ 4x² ⇒ 0 from the positive region because x² is always positive.
Then when x is a very big number (positive or negative), f(x) will be approximately 0 and positive.
Answer:
The points are: (16.12,0),(-8.12,0).
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots
such that
, given by the following formulas:



Distance between two points:
Suppose we have two points,
and
. The distance between them is given by:

Find all points on the x-axis that are 14 units from the point (4, -7).
Being on the x-axis mean that they have y-coordinate equal to 0, so the point is (x,0).
The distance is 14. So






So 



The points are: (16.12,0),(-8.12,0).
We have the same denominator. Therefore:
