Answer:
The claim can be determined by the probability method which will determine the percentage of battery lasting to an average of 16 hours.
Step-by-step explanation:
Probability method in statistics helps to determine the percentage of an event in certain circumstances. In the given scenario the claim is made that battery lasts an average of 16 hours. This claim can be verified by the probability check though standard deviation from the observation.
1/3 = 20 seconds so 3/3 = one minute
A graph shows the solutions to be
.. x = -3
.. x = 1
Here's an analytic solution.
.. f(x) = g(x)
.. -2x = x^2 -3 . . . . . . substitute the given function definitions
.. 0 = x^2 +2x -3 . . . . add 2x
.. 0 = (x -1)(x +3) . . . . . factor
Use the zero-product rule to find values of x that are solutions. One or the other of the factors must be zero for the product to be zero.
.. x -1 = 0 . . . . first factor is zero
.. x = 1
.. x +3 = 0 . . . second factor is zero
.. x = -3
Answer:
<u>The scale factor is 1.25 and this represents an enlargement.</u>
Step-by-step explanation:
As shown at the figure
The side length of the first hexagon = 5
The side length of the second hexagon = 6.25
So, the scale factor = 6.25/5 = 1.25
and the second hexagon is larger than the first hexagon.
So,
<u>The scale factor is 1.25 and this represents an enlargement.</u>
3/10 + 17/100
first make the 10 of the 3/10 turn into a 100 so it will make the 100 of the 17/100.
to make 10 turn into a 100 you multiply it by 10. if you're going to multiply the bottom number by 10 then you have to do the same thing with the top number:
3/10 * 10/10
3*10=30
10*10=100
new equation:
30/100 + 17/100
now just add the top numbers and leave the 100's alone:
<span>30/100 + 17/100
</span>30+17=47
<span>30/100 + 17/100 = 47/100</span>
