8 groups is what i suppose
Hope this helps!!! ;-)
Answer:
-0.89 (i think)
Step-by-step explanation:
Since the graph seems to be going downwards from the right, it has a negative correlation. And since the data seems to be pretty close together, the correlation must be strong. That narrows the answer down to -0.89
If its wrong then i'm not a smart person, and it's -0.15
Answer:
48
Step-by-step explanation:
-2(1)^2(3(1)^2 – 7(1) + 10)
-2^2(3^2 – 7 + 10)
4(9 - 7 + 10)
4(12)
48
The value of the cosine ratio cos(L) is 5/13
<h3>How to determine the cosine ratio?</h3>
The complete question is added as an attachment
Start by calculating the hypotenuse (h) using
h^2 = 5^2 + 12^2
Evaluate the exponent
h^2 = 25 + 144
Evaluate the sum
h^2 = 169
Evaluate the exponent of both sides
h = 13
The cosine ratio is then calculated as:
cos(L) = KL/h
This gives
cos(L) =5/13
Hence, the value of the cosine ratio cos(L) is 5/13

Step-by-step explanation:
When the car stops, the speed is zero.
When S = 0, -10t + 45 = 0, t = 4.5.
Hence it will take 4.5 seconds for the car to stop.
