Answer:
8
Step-by-step explanation:
The median is the middle of the numbers in a given data set.
To find the median, line up all of the numbers from greatest to least.
4, 6, 7, 9, 9, 10
Now, find the middle of the numbers. Since there is an even number of numbers in the data set, find the two middle numbers.
4, 6, 7, 9, 9, 10
Next, find the average of these two numbers. (To do this, add the numbers and divide that sum by 2.)
7 + 9 = 16
16/2 = 8
Therefore, the median is 8.
Answer:
$21.00
Step-by-step explanation:
1(x+3)+x=45
x+3+x=45
x+x=42
2x=42
x=21
Answer:
Step-by-step explanation:
The x-intercepts are the points with y- coordinate of 0
- (x - 3)(x + 8) = 0
- x - 3 = 0 or x + 8 = 0
- x = 3 or x = - 8
a) x-intercepts are
b) midpoint of x-intercepts is
- (3 - 8)/2 = - 5/2 = - 2.5
c) The extheme value has x- coordinate of - 2.5 and y- coordinate
- (-2.5 - 3)(- 2.5 + 8) = (-5.5)(5.5) = - 30.25
d) f(- 2.5) = - 30.25
<span>= 6x2 − 3 − 5x3 − 4x3 - 2x2 + 8
= </span>− 9x3+ 4x2 + 5
answer is <span>−9x3 + 4x2 + 5 (second choice)</span>
Answer:
Step-by-step explanation:
s=18, t=18 the s gives t x sweets
s=18-x, t=18+x, s eats 5 and t eats half
s=18-5-x, t=(18+x)/2
Reamining sweets is
R=s+t
R=18-5-x+(18+x)/2
R=13-x+(18+x)/2
R=(26-2x+18+x)/2
R=(44-x)/2
