Ok, so in the problem there are 5 angles given but you really only need to focus on <KNL and <MNL. these two angles are a linear pair, or supplementary, which means that they add up to 180˚. so, if <KNL is 38˚, then <MNL is 142˚. 180-38=142
hope this helped

Step-by-step explanation:
Answer:
a. About 64
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 70
Standard deviation = 5
Use the empirical rule to determine the number of students who scored less than 65 or more than 75?
65 = 70 - 5
So 65 is one standard deviation below the mean
75 = 70 + 5
So 75 is one standard deviation above the mean.
By the Empirical Rule, 68% of the students scored between 65 and 75. The other 100-68 = 32% scored less than 65 or more than 75.
Out of 200, that is
0.32*200 = 64
So the correct answer is:
a. About 64
Answer:
B. 33 cm^2
Step-by-step explanation:
w=8 so
w^2 - 2w - 15 =
8^2 - 2(8) - 15 =
64 - 16 - 15 =
48 - 15 =
33
Step-by-step explanation:
$13.50 per hour. 40 hours per week.
that makes her regular weekly income
40×13.5 = $540.00
in that particular week she had 8 his overtime in addition.
the overtime hourly rate is
13.5 × 1.5 = $20.25
so, she earned an additional
8×20.25 = $162.00
therefore she earned in that week in total
540 + 162 = $702.00
