Answer:
t ≤ 3 ; kindly check explanation for more explanation
Step-by-step explanation:
Given that :
Number of tulip (t) =?
Cost of bulb = $1.50
Pot for each bulb purchased at =$1.25
Bag of potting soil = $10.00
Number of tulip bulb that can be purchased without spending more than $20
Cost of tulip bulb = [(cost per bulb + cost per pot) * number purchased (t) + cost of bag of potting soil]
Cost = [(1.50 + 1.25)t + 10]
If spending should not exceed $20
2.75t + 10 ≤ 20
2.75t ≤ 20 - 10
2.75t ≤ 10
t ≤ 10/2.75
t ≤ 3.64
He cannot purchase more than 3 tulip bulbs
Anika cannot buy exactly enough tulip bulbs an pot to spend the full $20 because the number obtained is a fraction and not a whole number.
Consider the system of inequalities
1. Plot all lines that are determined by equalities (see attached diagram)
2. Determine which bounded part of the plane you should select:
- means that you should take points with y-coordinates greater than or equal to 2 (top part of the coordinate plane that was formed by the red line);
- means that you should take points with x-coordinates less than or equal to 6 (left part of the coordinate plane that was formed by the blue line);
- for you can check where the origin is placed. Since , the origin belongs to the needed part and you have to take the right part of the coordinate plane that was formed by green line.
- for you can check where the origin is placed. Since , the origin belongs to the needed part and you have to take the bottom part of the coordinate plane that was formed by orange line.
3. According to the previous explanations, the shaded region is as in A diagram.
Answer: correct choice is A.
Answer:
99.7% data lies between 13 to 43
Step-by-step explanation:
Mean:
Standard deviation :
68% of data lies between to
95% of the data lies between to
99.7% data lies between to
We are supposed to find 99.7 of the data will lie between which values
99.7% data lies between to
99.7% data lies between 13 to 43
Hence 99.7% data lies between 13 to 43
Number 7 is the x axis 11 is (4,2)
The Length of the play ground is 15 meter. The width is 5 meters. 15x5=75 and since 15 is 3x larger than 5 they should be the numbers we are looking for here.
So 15+15+5+5= 40 the perimeter of the playground should be 40 meters.
I hope this helps!
