First you plug in the missing values
5(8×5/8+3×3-5×2) = 20
Answer:
You need to categorize this to the form y=mx+c / y=mx+b
So,
12y=y & 3x=x
(Just let me know if u need further explanation or if this wasn't the ans. u were looking for)
Answer:
6.0520
Step-by-step explanation:
Given that:
Mean = 5.85
Standard deviation = 0.24
Let N denote the 80th percentile.
P(X < N) = 0.8
Using the Excel formula: = NORM.INV(0.8,5.85,0.24)
The 80th percentile for the diameters of mandarin oranges:
= 6.0520 (to 4 decimal place)
Answer:
Width of 6ft and length of 9ft
Step-by-step explanation:
The sandbox has a ratio of 2:3. If you plug the numbers in with the ratio, you can find the actual dimensions.
Let x be the length
Let y be the width
(Length)
2in / 3ft = 6in / (x)ft
2in / 3ft = 6in / <u><em>9ft </em></u>
(Width)
2in / 3ft = 4in / (y)ft
2in / 3ft = 4in / <em><u>6ft</u></em>
