Answer:
19.8 minutes
Step-by-step explanation:
Total time the 4 laps was completed = 4 x 2.5 = 10 minutes
Total time the 2 laps was completed = 2 x 4.9 = 9.8 minutes
total time = 10 minutes + 9.8 minutes = 19.8 minutes

Answer:
69
Step-by-step explanation:
Given the regression model :
y = 1.73x + 0.0924
Where,
y = number of pink flowers
x = Red flowers
Slope = 1.73
Intercept = 0.0924
The number of pink flower that are predicted to bloom on a shrub of 40 red flowers :
Put x = 40 and calculate the value of y
y = 1.73(40) + 0.0924
y = 69.2 + 0.0924
y = 69.2924
Number of pink flowers = 69
Slope is m given the general formula y=mx+b.
For this equation slope is -2
N P r = (n!)/((n-r)!)
8 P 4 = (8!)/((8-4)!)
8 P 4 = (8!)/(4!)
8 P 4 = (8*7*6*5*4!)/(4!)
8 P 4 = 8*7*6*5
8 P 4 = 1680
The final answer is 1680
