There is 10.5 cups that the pipe is leaking per week because there are 16 cups in a gallon
5 students like cheesecake because if there is 20 students in all and 15 like chocolate and the rest like cheesecake you do 20-15=5
If 5 students like cheesecake out of 20 it would be 5/20 20*5=100 just multiply by 5 5*5=25%
25% of students like cheesecake
Question:
Convert the angle θ=260° to radians.
Express your answer exactly.
θ = ___ radians
Answer:
260° = 13π/9 or 4.54 rad
Step-by-step explanation:
Given
θ=260°
Required
Convert from degree to radians
To convert an angle in degrees to radians, we simply follow the steps below.
1° = 1 * π/180 rad
Replace the 1° with x
So,
x° = x * π/180 rad.
Now, we assume that x = 260
This means that we substitute 260 for x. This gives
260° = 260 * π/180
260° = 260π/180
Divide numerator and denominator by 20
260° = 13π/9
We can leave the answer in this form or solve further.
Take π as 22/7. This gives
260° = 13/9 * 22/7
260° = 286/63
260° = 4.5396825397
260° = 4.54 rad (Approximated)
Answer:
Simple random sample
Step-by-step explanation:
Simple random sampling is a sampling technique where a smaller group of subjects are selected for study from a larger group. The subjects chosen are chosen at random, avoiding bias as each selected sample has an equal chance of selection.
This sampling technique is a basic technique used in science for blinded experiments or to carry out randomized control tests. The avoidance of bias in this sampling technique, creates a balanced subset, carrying the greatest potential for representing the larger group.
As in this case, from a large sample of 327, 15 selections were made randomly, forming the subset of the larger group to be studied. Another example will be a study to identify the average number of minutes, spent by 1000 employees to get to work daily. To conduct this study, 250 of the 1000 employees could be selected at random and the number of minutes spent by each one analysed. The overall average gotten is then used to address the larger group as a whole.
