Answer:
40 miles , 1 hour 30 mins
Step-by-step explanation:
(a)
His visit to Nicola is indicted by the horizontal part of the graph.
Using the vertical ( distance ) axis , this shows 40 miles
(b)
Using the horizontal ( time ) axis
The left side of the horizontal red line shows 10.00
The right side shows 11.30
Then 11.30 - 10.00 = 1 hour 30 minutes
Answer:
Check the explanation
Step-by-step explanation:
:proportion of male smoker lung deaths is same for the four given tar level categories.
:proportion of male smoker lung deaths is not the same for the four given tar level categories.
Expected frequency=1177/4=294.25
Tar level Observed Freq.(O) Expected Freq.(E) (O-E)^2/E
0-7 107 294.25 120.435
8-14 375 294.25 5.643
15-21 553 294.25 227.533
>=22 183 294.25 42.061
Total= 1177 1177 395.673
Total chi square score=395.673
df=4-1=3
p-value=CHIDIST(395.673,3)<0.001
p-value<0.001,Reject null hypothesis.
There is sufficient evidence that the proportion of male smoker lung deaths is not the same for the four given tar level categories.
The perimeter is 16 inches
4.5+5.5+6=16
So first you would have to make the two have common denominators. What we can do for that is say that they both go into 12. 1/6 x 2 = 2/12 and 3/4 x 3 = 9/12. Then we can add the two which is 2/12 + 9/12 = 11/12.
The correct Option is (D) 9x^4 + 21x^3 + 27x^2 + 24x + 9
Explanation: The product of the polynomials (3x^3 + 4x^2 + 5x + 3)(3x + 3) is:
3x(3x^3 + 4x^2 + 5x + 3) + 3(3x^3 + 4x^2 + 5x + 3)
9x^4 + 12x^3 + 15x^2 + 9x + 9x^3 + 12x^2 + 15x + 9
9x^4 + 21x^3 + 27x^2 + 24x + 9 (Option D)
