If the area of the old garden was 1m^2, then the side lengths were both 1
if she increases the lengths by 50%, then 1 turns into 1.5
1.5 times 1.5 is 2.25
The area of her new garden is 2.25m^2

For what value of the domain {–3, –1, 0, 2, 5} does f(x) = g(x) When f(x) = 3x – 4 and g(x) = x2 – 2

zavuch27 [327]

F(x) = g(x)
3(2) - 4 = (2)² - 2
6 - 4 = 4 - 2
2 = 2
I just substituted all the values in the domain to see which one would work. That's not really the quickest way but that's the only way I know

Identify the lower class limits, upper class limits, class width, class midpoints, and class boundaries for the given freque

bezimeni [28]

Answer:

See explanation and results below.

Step-by-step explanation:

We have the following data:

Age (yr) when award was won Frequency 25-34 31 35-44 36 45-54 12 55-64 4 65-74 6 75-84 1 85-94 2

If we order the data we got the following result. We assume that the midpoint is given by:

$Midpoint= \frac{L.Limit +U.Limit}{2}$

The $Class.Width = U.Limit-L.Limit$

And the limits are given by the lower and upper limit.

L.Limit U.Limit Class W Midpoint Frequency Limits

25 34 34-25=9 29.5 31 [25-34]

35 44 44-35=9 39.5 36 [35-44]

45 54 54-45=9 49.5 12 [45-54]

55 64 64-55=9 59.5 4 [55-64]

65 74 74-65=9 69.5 6 [65-74]

75 84 84-75=9 79.5 1 [75-84]

85 94 94-85=9 89.5 2 [85-94]
