Answer:
2.861
Step-by-step explanation:
What is the value of the t score for a 99% confidence interval if we take a sample of size20? Thus, the t-score for a 99% confidence interval for sample size 20 is 2.861.
Answer:
X = -3
Y = -5
Step-by-step explanation:
2X - 3Y = 9
<u>- (-5X - 3Y) = 30</u>
7X + 0Y = -21
X = -3
2(-3) - 3Y = 9
- 3Y = 15
Y = -5

Step-by-step explanation:
43. A "Square" cornfield, which means all 4 sides has the same lenght BxH
164.000 ft^2=404.96 NO
156.816 ft^2=396 Yes
174724 ft^2=418 Yes
215908 ft^2=464.66 NO
44. it's the same here, if the area is 81. then each side of the square is 9
1st figure: it has 12 sides x9 =108
2nd figure: it has 10 sides x9=90
3rd figure: has also 12 sides x9=108
45. 13^3= 13x13x13 = 2197
46. 25^2= 25x25 = 625
47. 15^3= 15x15x15 = 3375
48. 34^2= 34x34 = 1156
49. 5 root121= 5 (11)=55
50. -6.root36= - 6 (6)= -36
51. 10 root3 (8) = 10(2) = 20
52. -4. root 144= -4(12) = -48
Step-by-step explanation:
Solve for a:
Step 1: Multiply both sides by b.
b=a
Step 2: Flip the equation.
a=b
---------------------------
Solve for b:
Step 1: Multiply both sides by b.
b=a
