Step-by-step explanation:
m1=m2=m3=m5
m4=m6=m7
find m1,m2,m3 or m5
=180°- m4 or m6 or m7
find m4,m6 or m7
=180°- m1 or m2 or m3 or m5
Its C 10d+ 5n I know it doesnt tell you numbers but a dime is 10 cents and a nickel is 5 cents which obviously would help you find the answer but you dont need the answer just how they would make it an problem so yea, its C 10d + 5n
Let the positive number be
The expression is
⇒ expanding the bracket gives,
⇒ rearranging to equate one side to zero
⇒ Dividing each term by 7 to simplify
⇒ Factorising gives
and
Hence, the first number is -5 and the second number is 3
To obtain the sample, one can choose the names of 6 students out of a hat from the students in the class using random sampling.
<h3>What is random sampling?</h3>
It should be noted that a simple random sample is a subset of a statistical population where each member of the subset has an equal probability of being chosen.
Systematic sampling is when the sample members from a larger population are selected based on a fixed, periodic interval. If you want to select a random group of 6 students from a population of about 60 using systematic sampling, every 10th person on the list is selected.
