Answer:
x = 2
Step-by-step explanation:
The sum of the 3 angles in the triangle = 180°
Sum the 3 angles and equate to 180
6x + 15 + 90 + 63 = 180
6x + 168 = 180 ( subtract 168 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2

Hey there!
Here is ur answer >>>>
A) 4(X + 1 ) = 5x + 12
4x + 4 = 5x + 12
X = 4 - 12
X = -8
B) 13 ( 6 - x ) - 4 ( 3x + 12 ) = 0
78 - 13x - 12x - 48 = 0
30 - 25x = 0
30 = 25x
X = 30/25
X = 6/5
All of them are solved in these methods
Answers 3 and 4! since there is a negative power, that’s the only time the 0’s are added to the front :)
Answer:
Pvalue = 0.063008
Step-by-step explanation:
Given :
Sample size, n = 63
The test statistic = - 1.53
To test if average room price is significantly different from $110 ; μ = $110
H0 : μ = 110
H1 : μ < 110
From the test statistic value obtained, we could see that the test is left tailed
The Pvalue :
P(Z < - 1.53) = 0.063008
If the claim is to be tested at 5% level of confidence then
Pvalue > 0.05 ; Hence, we fail to reject the. NULL. Hence, average price is not significantly different from $110
