Answer:
54.14
Step-by-step explanation:
Add them all up then divide by 7 because that is the number of numbers in the data set and you get a long decimal but I just rounded to the hundredths place
12in.=1ft
so 240in./12in. = 20ft
Answer: i don,t know sorry but i wish you the best of luck
Step-by-step explanation:
In this situation, you have:
The mode is 79 (that’s the most common number).
The median is 78.5 (the middle value or the average of the two middle values, since there is an even number of test scores).
The mean is less than both of those, as it was brought down by the few scores of 49.
The means the mean will be less than median.
Answer: C
Im assuming you mean 2x^2-3x-9=0 ?
If so, you have to factorise the equation
(2x-3) (x+3) = 0
2x - 3 = 0
2x = 3
x = 1.5
x + 3 = 0
x = -3
x is either 1.5 or -3
