Answer:
Option Y is correct.
Step-by-step explanation:
We are given the table representing the relation between new students and returning students for difference classes.
It is required to form the relative frequency table for the given situation.
So, relative frequency table is obtained by dividing the valued by the total number of values in the data set.
<em>Thus, we will get the relative frequency table by dividing the given table values by 500.</em>
Hence, we will get the following table,
New Students Returning Students Total
10th 0.01 0.34 0.35
11th 0.006 0.324 0.33
12th 0.004 0.316 0.32
Total 0.02 0.98 1
Thus, option Y is correct.
Answer:
50
Step-by-step explanation:
x-13=37
x=37+13
x=50
Answer:
We need to sketch the problem first.
Find the size of angle R.
One member travels a distance of 12km due north. Another team member heads 50degree east of north and travels a distance of 10km.
If se substute 50° of 180 we have
180-50=130°
The distance between the two team members is the missing side.
We know two sides and included angle, so we use the cosine rule.
A2+b2+c2-2bcCosA
= 102+122-(2x10x12xcos130°)
=100+144-(-147.08)
=100+144+147.08
=391.08
A==SQRT391.08
=19.775
19.7km
Step-by-step explanation:
The time for the job for which the two company are the same is 16
<h3>How to form the equation and find the cost?</h3>
A yard cleanup service charges a $345 fee plus $16.25 per hour. Therefore,
using linear equation,
y = mx + c
where
Therefore,
y = 345 + 16.25x
Another cleanup service charges a $213 fee plus $24.50 per hour. Therefore,
y = 213 + 24.50x
Hence, the time when both cost are the same is as follows;
213 + 24.50x = 345 + 16.25x
213 - 345 = 16.25x - 24.50x
-132 = -8.25x
x = 132 / 8.25
x = 16
