Answer:
y=-4x+2
Step-by-step explanation:
Hi there!
We want to find out which equation represents a line with a slope of -4 and a y intercept of (0,2)
The most common way to write the equation of the line is in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
We have everything we need to plug into the equation, let's just label the values to avoid confusion
m=-4
b=2 (when you substitute the y intercept as b, b is the value of y in the point)
Now substitute into the equation
y=-4x+2
Hope this helps!
Answer:
it saves 2.5 minutes
Step-by-step explanation:
The expected value of a random variable is the sum of products of possibilities and the probability of each.
Here, you have a probability of 0.9 of saving 5 minutes, and a probability of 0.1 of adding 20 minutes.
__
The expected value of the shortcut is ...
0.9(-5) +0.1(20) = -4.5 +2.0 = -2.5
The shortcut is expected to save 2.5 minutes on average.
_____
<em>Additional comment</em>
The probability of 0.9 comes from the 9 of 10 trips that result in a time saving.
Answer:
Yes
Step-by-step explanation:
0.7988-0.5= 0.7488
0.7988+0.5= 1.2988
0.7925 lies between these values.
however, are you certain that the question has 0.500 as the uncertainty not 0.050
Hello, This is correct.
first one is whole numbers
the third one natural numbers
the fourth are complex numbers
The last one is irrational numbers
Answer:
therefore the answer of the total interest at the end of 12 years is
B) $1,680,00
Step-by-step explanation:
$4,000 x 3.5 = $14,00
$14,000 x 12 = $1,680,00
Hope this helped (:
