Step-by-step explanation:
Answer:
1) 425000
2) 62.570000
Step-by-step explanation:
There are 5 under the 10.
1) 10 x 10 x 10 x 10 x 10 = 100000
100000 x 4.25 = 45000
2) There are 7 under the 10.
10 x 10 x 10 x 10 x 10 x 10 x 10 = 10000000
10000000 x 6.257 = 62.570000.

Answers
The area of a rectangular model is 64k²+72.
Given that, the length of a rectangle = 8k+9 units and the width of a rectangle = 8 units.
What is the area of a rectangle?The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.
Now area of a model is
(8k+9)×8
= 8×8k+8×9
= 64k²+72

The answer is x > 6.
Reasoning:
2x + 4 > 16You have to subtract 4 from both sides:2x + 4 > 16
-4 > -4
2x > 12
16 subtract from 4 is 12. You then divide the 12 by the 2.2x > 12

Complete Question
The Henderson Hawks minor-league baseball team is giving away baseballs an
game. The balls cost $3 each and the towels cost $2 each. The team wants to give away 200 items and have 500 to spend. How many of each item should the team give away Show your
work or explain your reasoning.
Answer:
They should give away 100 balls and 100 towels
Step-by-step explanation:
Let the number of balls = x
Let the number of towels = y
x + y = 200........ Equation 1
y = 200 - x
$3 × x + $2 × y = $5000
3x + 2y = 5000...... Equation 2
3x + 2(200 - x)= 5000
3x + 400 - 2x = 5000
Collect like terms
3x - 2x = 500 - 400
x = 100
Number of balls to be given away = 100
Note:
y = 200 - x
y = 200 - 100
y = 100
Number of towels to be given away = 100
Therefore, they should give away 100 balls and 100 towels

what is the slope of (7,1) (1,-7)
Answers
Answer:
The slope of the points (-3,2) (-5,-2) is 2
The slope of the points (7,1) (1,-7) is 4/3
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1)
Plug in the points given and find the slopes:
(y2 - y1) / (x2 - x1)
(-2 - 2) / (-5 + 3)
-4/-2
= 2
Find the next slope:
(y2 - y1) / (x2 - x1)
(-7 - 1) / (1 - 7)
-8/-6
= 4/3
The slope of the points (-3,2) (-5,-2) is 2
The slope of the points (7,1) (1,-7) is 4/3

Answer: 0.54
Step-by-step explanatio;
We would have three in common out of 4 characteristics (4 out of 4 is not possible). There are 4 possible ways to share 3 out of 4 characteristics.
Denoting the characteristics as {M,C,Si,Sh} so P(B2={1,1,1,0}|B1={1,1,1,0}) is the probability that box 2 shares its first three characteristics with box 1 given that box one has characteristics
We now have
P(B2 has 3 elements in common with B1)=P(B2={1,1,1,0}|B1={1,1,1,0})xP(B1={1,1,1,0})+P(B2={1,1,0,1}|B1={1,1,0,1})xP(B1={1,1,0,1})+P(B2={1,0,1,1}|B1={1,0,1,1})xP(B1={1,0,1,1})+P(B2={0,1,1,1}|B1={0,1,1,1})xP(B1={0,1,1,1})
P(B2 has 3 elements in common with B1)=(4x5x24+3x4x30+2x3x40+1x2x60)1120x119= 0.084
which is close enough to the value from the simulation code (modified to count the number of 3-ties)
Now, I use the same reasoning to compute:
P(B2 has 2 or more elements in common with B1)=(19x20x6+11x12x10+9x10x12+14x15x8+7x8x15+5x6x20)1120x119= 0.54
Equation: (2-1)((3-1)+(4-1)+(5-1)) + (2)((3)+(4)) + (12) = 35 with a total of 119 possibilities.
answer: 35/119
