Answer:
∠KMN = 66°
Step-by-step explanation:
In ΔKMN,
∠MKN + ∠KNM + ∠KMN = 180 {Angle sum property of triangle}
39 + 75 + ∠KMN = 180
114 + ∠KMN = 180
∠KMN = 180 - 114
∠KMN = 66°
Answer:
95 degrees
Step-by-step explanation:
A supplementary angle is an angle that equals 180 degrees. Here it shows that 85 degrees + x = 180 degrees, since part of the supplementary angle has already been taken up by the 85 degrees and x is remaining. Therefore, solve the equation for x.
85 + x = 180
x = 95
Using the Empirical Rule, it is found that 68% of the data should be between 25.5 and 30.5.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Within one standard deviation of the mean, hence, 68% of the data should be between 25.5 and 30.5.

Number of cone left is 75 cone
<u>Given that;</u>
Cost of each cone = $3.75 each
Starting number of cone = 300
Total amount earn = $843.75
<u>Find:</u>
Number of cone left
<u>Computation:</u>
Number of cone sale = Total amount earn / Cost of each cone
Number of cone sale = 843.75 / 3.75
Number of cone sale = 225 cone
Number of cone left = Starting number of cone - Number of cone sale
Number of cone left = 300 - 225
Number of cone left = 75 cone
