Answer:
C
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr × 
= 2π × 18 × 
= 36π × ( cancel 36 and 24 by 12 )
= 3π × 
= 
→ C
First divide both sides by 5.9 and that will give you an answer of 4
Answer:
a) Robert, Juan, linda
b) Joel
c) Susan, Jan
d) 165.4
173.4
134.5
156
147.3
170.2
Step-by-step explanation:
The standardized normal distribution N (0,1) that expresion stands for normal distribution with mean 0 and standard deviation 1, therefore all positive values are above 0 and all negativa values are below 0
The sample n is 6 then we should use t-student distribution, we calculate t statistic as follow
t = (x-μ)/εε where standard error is εε = σ/√6 εε = 9.795 since σ =24
Robert
0.96 * 9.795 = x - 156 ⇒ x = 165.4
1.78 * 9.795 = x - 156 x = 173.4
-2.2 * 9.795 = x - 156 x = 134.5
0 * 9.795 = x- 156 x= 156
-0.89* 9.795 = x -156 x = 147.3
1.45 * 0.9795 = x -156 x = 170.2
Answer:
x=6
Step-by-step explanation:
2x+7=9x-35
-2x -2x
(two cancels out on left side and 9x becomes 7x)
7=7x-35
+35 +35
(35 cancels on right side and is added to left)
42=7x
/7 /7 (divide both sides by 7)
x=6
