Answer:
The answer is 78%
Step-by-step explanation:
Step 1: The given regression equation y = -0.414x + 106.55
Step 2: The length of the film = 70 minutes
Step 3: Plug in x = 70 in the given equation and find the value of y.
y = -0.414 (70) + 106.55
y = -28.98 + 106.55
y = 77.57
Y = 78%

Answer is N= - 4
Answer:
Month since April Number of Ants
0 10,000
1 30,000
2 90,000
3 270,000
4 810,000
Every month, the ant population triples so the multiply the previous population by 3 to find out the new population.
0 months from April = 10,000 * 1 = 10,000 ants
1 month from April = 10,000 * 3 = 30,000 ants
2 months from April = 30,000 * 3 = 90,000 ants
3 months from April = 90,000 * 3 = 270,000 ants
4 months from April = 270,000 * 3 = 810,000
Answer:
7/5
Step-by-step explanation:
reciprocal means flip the equation
Step-by-step explanation:
x²+3x+4=0
x²+3x_ +2=0
x²+3x_2=-2
x²+3x_2+(3x_4)²=-2+(3/4)²
(x+3/4) =-2+9_16
x+3_4 = -32+9__16 =√-23_6
x+3_4 =-√23_4
x = -3+√-23___4
x = -3- √-23___4 , -3+√-23___4 //
