Step-by-step explanation:
Answer:
-4,-5
Step-by-step explanation:
first set the equation equal to 0, v^2+9v+20, factor v^2+4v+5v+20, v(v+4) 5(v+4), so the 2 factors are (v+5) and (v+4), set both equal to that 0. v+5=0 v=-5 and v+4=0 v=-4, so the answer is -4 and -5
Answer:
In think the answer is 42,000
Step-by-step explanation:
Answer:
b) Chemistry
Step-by-step explanation:
To compare both scored we need to standardize the scores using the following equation:
Where x is the score, m is the mean and s is the standard deviation. So, 82 on chemistry is equivalent to:
Because the mean of the scores on the chemistry final exam is equal to 75 and the standard deviation is 15
At the same way, 80 on Calculus is equivalent to:
Because the mean of the scores on the calculus final exam is equal to 83 and the standard deviation is 13
Now, we can compare the values. So, taking into account that -0.2308 is lower than 0.4667, we can said that the student do better in Chemistry.
Domain is input/numbers you can use
range is the output you get from inputing the domain
domain=-3,-1,0,1,3
input those numbers for x and get y (range)
y=4(-3)+7
y=-5
y=4(-1)+7
y=3
y=4(0)+7
y=7
y=4(1)+7
y=11
y=4(3)+7
y=19
range is {-5,3,7,11,19}
