6 is the answer because it is 6x therefore the gradient increases by 6 each time<span />
Here’s the answer. You just plug the y=-2+6 into -4x-6y=7.
Answer:
The correct answer is - 97.74%.
Step-by-step explanation:
Given:
sample mean = 281
Std Dev = 47 ==> Sample
Std Dev (s) = std dev/sqrt(n) = 6.0677
Solution:
Find : P( x > 268 )
z = ( x - u )/s = ( 268 - 281 )/6.0677
= -1.9558
then, P( x > 270) = P( Z > -1.9558)
= P( Z <1.9558)
= 0.9747
change into percentage:
= 97.471%

equation:
Answer:
t = -1.24
Step-by-step explanation:
From the equation;
t = 0.0119s² - 0.308 s -0.0003
Where t is the change in a runner's performance, and s is the tail wind speed.
But s = 5 m/s
Therefore;
t = 0.0119 (5²) - 0.308(5) -0.0003
= 0.2975 - 1.54 - 0.0003
= - 1.2428
Since, negative means a runner finishes with a lower time, then;
t = -1.2428 to the nearest hundredth
= -1.24
