le'ts take a peek at the ages, 9, 6 and 5, so their ratio will be in the order of 9:6:5, what we firstly do is divide the total by that many pieces, namely 100 ÷ (9+6+5) and then distribute accordingly.
Answer:
She purchased 10 tickets.
Step-by-step explanation:
She spent $21.45
x represents the amount of tickets she purchased.
So,
0.75x+4.95=21.45
If we solve for x, then we know how many tickets she got.
0.75x + 4.95 - 4.95 = 12.45 - 4.95
0.75x = 7.5
x = 10
So, she bought 10 tickets
A practical application of the trigonometric functions is to find the measure of lengths that you cannot measure. Very frequently, angles of depression and elevation are used in these types of problems.
Angle of Depression: The angle measured from the horizon or horizontal line, down.
Angle of Elevation: The angle measure from the horizon or horizontal line, up.
Answer:
Simple random sampling
Step-by-step explanation:
Every element of the population does have an equal probability of getting chosen in a basic random sampling. The entire population should be included in your sample frame. To conduct this sort of sampling, technologies such as random numbers or other approaches relying completely on chance can be used.
