If your looking for the expression its
- _5(3a+b)_
6
the negative goes before all of it not before the 5.
hopefully this helped some??
Answer:
Step-by-step explanation:
Use FOIL method.First multiply (5x + 1) and (3x - 4). Then multiply (15x² - 17x - 4) by (x +2)
Volume of the rectangular prism = length *width * height
= (5x + 1) (3x -4)(x +2)
= [ 5x*3x + 5x*(-4) + 1*3x + 1*(-4) ] (x + 2)
= [15x² <u>- 20x + 3x</u> - 4] (x +2) {Combine like terms}
= [15x² - 17x - 4] (x + 2)
=[15x² -17x - 4]*(x) + [15x² - 17x -4]*2
= [15x²*x - 17x*x - 4*x ]+ 15x²*2 - 17x *2 - 4*2
= 15x³ - 17x² - 4x + 30x² - 34x - 8
= 15x³ <u>- 17x² + 30x²</u> <u>- 4x - 34x </u>- 8 {Combine like terms}
= 15x³ + 13x² - 38x - 8
The relative frequency probability that an accurate forecast will be made the next day is ratio of the number of correct predictions made to the total number of predictions is 0.575
The total number of predictions made = 40
The number of correct predictions = 23
The relative frequency probability is given by ;
- Number of correct predictions ÷ total number of predictions made
Therefore, the relative frequency probability that an accurate forecast will be made tomorrow is 0.575
