None of the graphs are for any translation of y = 3x. All are for a translation of
y = 3^x . . . . . where x is an exponent, not a multiplier
Please use correct mathematical notation. This may require you to edit your pasted question before you post it.
The transformation from f(x) to f(x) +2 causes the graph to be shifted upward by 2 units. The last selection is the correct one.
Answer:
The probability is 0.683
Step-by-step explanation:
To calculate this, we shall be needing to calculate the z-scores of both temperatures
mathematically;
z-score = (x-mean)/SD
From the question mean = 78 and SD = 5
For 73
z-score = (73-78)/5 = -5/5 = -1
For 83
z-score = (83-78)/5 = 5/5 = 1
So the probability we want to calculate is within the following range of z-scores;
P(-1 <z <1 )
Mathematically, this is same as ;
P(z<1) - P(z<-1)
Using the normal distribution table;
P(-1<z<1) = 0.68269 which is approximately 0.683
Answer:
2116.8 in^3
Step-by-step explanation:
V = l*w*h
All the units need to be the same
Convert 1.4 ft to inches
1.4 ft * 12 inches/ ft = 16.8 inches
V = 14 * 16.8 * 9
= 2116.8 in^3
-- Look at the two numbers.
-- Say to yourself: "Self ! 3.9 is close to 4, and 5.3 is close to 5.
So the product is going to be close to (4 x 5) = 20."
-- Then do the real multiplication.
-- On your paper or your calculator, you see the digits 2 0 6 7 .
-- From your estimate (20), you know that it can't possibly be
2.067 or 206.7 or 2,067. It must be 20.67 .
