For example, a classroom of 30 students with 15 males and 15 females could generate a representative sample that might include six students: three males and three females
so true i think
Answer:
Company B pays more!
Step-by-step explanation:
All you have to do is...
25,000x10=250,000
+
1,600x10=16,000
= 266,000(company a)
28,500x10=285,000
+
700x10=7,000
= 292,000(company b)
2x + x = 54 wher x = number of girls
3x = 54
x = 18
18 girls
The measures of the angles of a triangle add up to 180 degrees.
<span>This is true of all triangles.
You have two given angles of triangle PQR.
They are 24 degree and 100 degree.
<span>What do those measures add up to?
</span><span>What is 100 + 24? = 124
</span>
When you add the measure of the third angle to 124, you must get 180.
To find the measure of the third angle, just do 180 - 124.
<span>What do you get?
</span>
180 - 124 = 56
That means the third angle of triangle PQR measures 56 deg.
Now we know the measures of all three angles of triangle PQR: 24, 100, 56.
Triangle RST has two angles that measure 24 deg. and 56 deg.
<span>Since two angles of triangle PQR are congruent to two angles of triangle RST, the triangles are similar.</span>

Answer:
ft/min is the rate of changing of width
Step-by-step explanation:
Given -
The area always remain constant i.2 2 square feet.
Height of the rectangle = 2 feet
Rate of changing of height = 6 feet per minute
Since area is constant
2 sq ft = (2 * 6) ft/min * 1 * x ft/min
x = ft/min
