Answer:
Area - 6 unit^2 Perimeter - 10 units
Step-by-step explanation:
The shaded figure is 3 units long and 2 units high.
L = 3 W = 2
A = LW
A = 3 x 2 = 6 unit^2
Perimeter = 2L + 2W
P = 2(3) + 2(2)
P = 6 + 4 = 10 units
Answer:
Chi-square = 4.600
Degrees of freedom= 6
there is no evidence to reject hypothesis.
Step-by-step explanation:
H₀ : uniformly distributed
H₁: not uniformly distributed
Suppose some value of observed or expected frequency
Observed frequency : 39 40 30 40 41 49 41 Total: 280
Expected frequency : 40 40 40 40 40 40 40 Total: 280
Calculated the chi-square value
Chi-square = sigma {(O-E)^2/E}
= 0.025+0.000+2.500+0.000+0.025+2.025+0.025
4.600
Degrees of freedom=d f = n-1 = 7-1 = 6
Chi-square for 6 d.f at alpha = 0.05 is 12.59
Chi-square of calculated value < its critical value at alpha = 0.05, we see that there is no evidence to reject hypothesis.
The frequency of Sat is wrongly taken as 41 instead of 51
Answer:
I think the answer would be -1/2 or D.
Step-by-step explanation:
Use this formula for calculating slope : y2-y1 / x2 - x1
1. label the pairs, 1 and 2
(-6, 1) - ( x1, y1 ) or (4,-4) - (x1, y1)
(4,-4) - ( x2, y2) (-6,1) - (x2, y2)
(the order does not matter)
2. Than plug in your numbers
y2-y1 / x2 -x1 y2-y1 / x2 -x1
-4 - 1 / 4 - (-6) or 1 - (-4) / -6 - 4
= -5/10 or -1/2 = - 5/-10 or -1/2
im only in eight grade so i did my best explaining , and this hope it helps :)
