Answer:
5
Step-by-step explanation:
Given :
Observed values = 5, 10, 15
Expected freqencies = 10
χ² = Σ(observed - Expected)² / Expected
χ² = (5-10)²/10 + (10-10)²/10 + (15-10)²/10
χ² = 25/10 + 0/10 + 25/10
χ² = 2.5 + 0 + 2.5
χ² = 5
Answer:
Step-by-step explanation:
4.2x+4.7=18.6
Multiple each term by 10
42x + 47 = 186
Collecting like terms
42x = 186 - 47
42x = 139
x = 139/42
x = 3 13/42 or 3.3
Answer:
it would be about 5984 times around the earth
Step-by-step explanation:
first of all 149,000,000 miles is active lifetime
Using those measurements, the equatorial circumference of Earth is about 24,901 miles
so therefore if you divide 149,000,000 by 24,901 you would get the answer of 5983.69543392 so if you round all the numbers to the nearest whole number you would get 5984
hope tis helps out with your question
First Answer:
A)fails the vertical line test at (2,3) and (2,-2)
Second Answer:
B) not a function
=========================================
Further Explanation:
It is possible to pass a single vertical line through this red curve. So it is not a function because it fails the vertical line test. One specific line goes from (2,3) to (2,-2) but there are infinitely other lines to choose from. In order to pass the vertical line test, it must be impossible to pass a vertical line through more than one point on the curve. A function is where any given input leads to exactly one output. In the case of (2,3) and (2,-2), the input x = 2 leads to more than one output (y = 3 and y = -2) at the same time
Answer:
$300 is the regular price
Step-by-step explanation:
(100%-33%) = 67%
67% * x = $201
x = $201 / 67%
x = $201 * 100 / 67 = $20100 / 67 = $300
