Answer:
- 6x / 5
Explanation:
Multiplicative inverse is the negative reciprocal of a fraction.
Answer:
D
Step-by-step explanation:
6.8 = (6/5)^x
6.8 = 1.2^x
x ln 1.2 = ln 6.8
x = ln 6.8 / ln 1.2
= 10.513966
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
The measure of angle R is 50° because x=3.
