Answer:
69.1
Step-by-step explanation:
<em>Mean height of 14 students = 69.0 inches</em>
<em>Mean = sum of data/number of data</em>
<em>69 = sum of data/14</em>
<em>sum of data = 966</em>
<u>FOR NEW MEAN:</u>
<em>Height of additional student = 70.5</em>
Mean = sum of data/ number of data
Mean = 966+70.5/14+1
Mean = 1036.5/15
Mean = 69.1
Therefore, the mean height of the 15 students in the class is 69.1
3/5 is the greatest because when you change 3/5 to percantage, it will be 60%.
Answer:
Part A)
m<BDG=m<MPQ
m<DBG=m<PMQ
m<DGB=m<PQM
Part B)
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent
Part A)
we have that
the congruent angles are
m<BDG=m<MPQ
m<DBG=m<PMQ
m<DGB=m<PQM
Part B) The ratio of its corresponding sides is equal to
To solve for the true hourly wage simply add the 2 rates together.
20 dollars/500 hours = 2/50 = 0.04 dollars per hour.
The true rate would be $18.000 + $0.04 = $18.04 per hour.
