- 4.6 p - 6.3 p + 3.9 = -9.18
- 10.9 p + 3.9 = - 9.18
- 10.9 p = - 9.18 - 3.9
- 10.9 p = - 13.08
p = ( - 13.08 ) : ( - 10.9 )
Answer:
p = 1.2
Answer:
A) 34x²
Step-by-step explanation:
6x * 7x = 42x²
2x * 4x = 8x²
42x - 8 x = 34x²
Answer: f) None of the above
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 5.6ft
Standard deviation r = 1.0ft
Number of samples n = 27
Confidence interval = 90%
z(at 90% confidence) = 1.645
Substituting the values we have;
5.6+/-1.645(1.0/√27)
5.6+/-1.645(0.192)
5.6+/-0.317 ft
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
It has 3 sides I don’t know what other answers there is
Answer:
-3
Step-by-step explanation:
Simplifying
4(4m + -3) + -1(m + -5) = -52
Reorder the terms:
4(-3 + 4m) + -1(m + -5) = -52
(-3 * 4 + 4m * 4) + -1(m + -5) = -52
(-12 + 16m) + -1(m + -5) = -52
Reorder the terms:
-12 + 16m + -1(-5 + m) = -52
-12 + 16m + (-5 * -1 + m * -1) = -52
-12 + 16m + (5 + -1m) = -52
Reorder the terms:
-12 + 5 + 16m + -1m = -52
Combine like terms: -12 + 5 = -7
-7 + 16m + -1m = -52
Combine like terms: 16m + -1m = 15m
-7 + 15m = -52
Solving
-7 + 15m = -52
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '7' to each side of the equation.
-7 + 7 + 15m = -52 + 7
Combine like terms: -7 + 7 = 0
0 + 15m = -52 + 7
15m = -52 + 7
Combine like terms: -52 + 7 = -45
15m = -45
Divide each side by '15'.
m = -3
Simplifying
m = -3
Hope this helped :)
