Given the diagram of parallelogram LMNO, solve for s.

Evgen [1.6K]

< o and < m are congruent because opposite angles are congruent
3t - 15 = 2t + 10
3t - 2t = 10 + 15
t = 25

3t - 15 = 3(25) - 15 = 75 - 15 = 60...< m = 60

< m and < o are consecutive angles and they are supplementary....so they add up to 180
< m + < o = 180
60 + < o = 180
< o = 180 - 60
< o = 120

3s = 120
s = 120/3
s = 40

If the level of significance (alpha) is 0.05, it means that the probability of rejecting the null hypothesis, when it is false,

Kaylis [27]

Answer: The probability of rejecting the null hypothesis, when it is true, is 5%.

Step-by-step explanation:

We know that the level of significance ( denoted as $\alpha$ ) is generally the probability of rejecting the null hypothesis when it is true.

Therefore , If the level of significance (\alpha[/tex] ) 0.05, then it means that it is the probability of rejecting the null hypothesis when it is true.

i.e. The probability of rejecting the null hypothesis when it is true= 0.05

In percent : $0.05=5\%$

Hence, the correct option is : The probability of rejecting the null hypothesis when it is true is 5%.

Line L is perpendicular to the line with equation x + 2y = 8 and passes through the origin. Determine the equation of line L.

MAXImum [283]

When lines are perpendicular, they slopes are opposite reciprocal. Opposite reciprocal means that the slope is flipped and then changed from negative to positive.
