Step-by-step explanation:
(x-3)² - 7 = (5-3)²-7
= 2²-7
= 4 - 7
= -3
Answer:
Pick the best solution.
Step-by-step explanation:
Volume of a cone is V = ⅓πr²h
If cone diameter is 4.3
V = ⅓π(4.3/2)²(5.2) = 25.17148... ≈ 25.17 ft³
If cone radius is 4.3
V = ⅓π(4.3)²(5.2) = 100.685950... ≈ 100.69 ft³
If cone diameter is 5.2
V = ⅓π(5.2/2)²(4.3) = 30.439938... ≈ 30.44 ft³
If cone radius is 5.2
V = ⅓π(5.2)²(4.3) = 121.75975... ≈ 121.76 ft³

Answer:
The distribution is skewed, so use the five-number summary. range: 38, median: 16, half of the data are between 9.5 and 25
Step-by-step explanation:
In the picture attached the histogram is shown. We can see that data is skewed to the right, so we have to use the five-number summary. The range of the data is 39 - 1 = 38 (subtraction of the maximum value to the minimum value); the median is (15 + 17)/2 = 16 (if you order the values, 15 and 17 are in the middle); quartile 1 is 9.25 and quartile 3 is 25.5 (see diagram of box and whisker attached), then half of the data are between those values.
Judging by the problem you want me to use substitute method
Since why equals 1/2x-1 you
Do 2(1/2x-1)= x-2
You multiple by 2 cause there’s two on the top for y. So the problem is now 4x-x-2
Combine like terms 3x+2=14
Subtract two on both sides
3x=12
X=4
Go back to the bottom since u know x now do y= 4.1/2-1 solve to get one
Y=1 so your answer is (4,1)
