First you find the slope using y2-y1/x2-x1
which would be -6 and then to find the y-intercept plug in either (-3,-1) or (-4,-7) in x and y and plug in the slope -6
-1=-6(-3)+b
-1=18+b
-18. -18
-19=b
y=-6x -9
Answer: 4 fishes
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere = 4/3 x π x (diameter/2)^3
Replacing with the values given:
V = 4/3 x π x (18/2)^3
v = 4/3 x π x (9)^3 = 3,053.63 in3
Next, we have to divide the volume of the tank by 693 in3 (volume for each fish)
3,053.63/693 =4.40 = 4 fishes
Feel free to ask for more if needed or if you did not understand something.
Answer:
Step-by-step explanation:
Given
The attached shape
Required
Probability of locating within the shaded region
First, calculated the area of the shaded region
Where
--- given
So:
Next, calculated the area of the complete rectangle
Where
--- given
So:
The required probability is:
I like to do it by adding 4 and 3 to get 7. then divide 35 by 7. that would be 5. take 5*4 to get 20 boys and 5*3 to get 15 girls.
Answer: 90.2
Reasoning: You add all grades together. Next you dived by 5 because their are 5 grades. You then revive an average of 90.2
