Answer:
0.7 minute
Step-by-step explanation:
Given that each (1) minute a light use 9.4 watts.
So If the light bulb used a total of 6.58 watts, the minutes was on it is:
= 
= 0.7 minute
So the the minutes was on it is 0.7
Hope it will find you well!
Answer:
y = -1/2x + 13/2
Step-by-step explanation:
The slope of a line that is perpendicular to a line will be a negative reciprocal. When you rewrite 2x-7=8 into slope-intercept form, you get y=2x-8. The negative reciprocal of the slope 2x is -1/2x. There is only one option with this slope. If you're still not sure then you can use a graphing calculator to check this. An online one would be desmos
Answer:
(8x-9)(8x+9)
Step-by-step explanation:
64x^2 - 81
Rewriting
(8x)^2 - 9^2
We recognize that this is the difference of squares
a^2 - b^2 = (a-b)(a+b)
(8x-9)(8x+9)
Answer:
(a) The probability is 0.64
(b) The probability is 0.59
Step-by-step explanation:
Say that an order requests at least one optional feature is equivalent to say that an order request one or more than one optional feature, So the probability can be calculated as the sum of this two proportions:
P = 0.23 + 0.41 = 0.64
Where 0.23 is the proportion or probability that an order request one optional feature and 0.64 is the probability that an order request more than one optional feature.
On the other hand, say that an order does not request more than one optional feature is equivalent to say that an order request zero or one optional feature, So the probability in this situation can be calculated as the sum of:
P = 0.36 + 0.23 = 0.59
Where 0.36 is the probability that an order doesn't request optional features and 0.23 is the probability that an order request one optional feature.
Step-by-step explanation:
Put the value of x = -6 to all expressions:
