Answer:
<u>870</u> people attend the school.
Step-by-step explanation:
Given:
Thad conducted a survey on hair color at his school.
His results were:
23 students had blonde hair, 38 students had black hair, 7 students had red hair and 19 students had brown hair.
Now, to find number of people attended school if he had sampled 1 out of every 10 students.
So, we add the total number of students who had been surveyed on hair color:
Then, we get the percentage of the sample of 1 out of 10 students:
<u><em>Thus, we get that 10% of students surveyed from the total who attend the school.</em></u>
Now, to get the number of people who attend school we set an equation:
Let the people attend the school be .
So,
⇒
⇒
<em>Multiplying both sides by 100 we get:</em>
⇒
<em>Dividing both sides by 10 we get:</em>
⇒
Therefore, 870 people attend the school.
First question: you're given , , , and . So the value of the account after 3 years is
making the answer B.
Second question: and . APY is given by
so the APY in this case is
making the answer D.
Using the commutative property of multiplication, we get that 5.4*1.7*100=
5.4*100*1.7, so we could multiply 5.4 and 100 first, then by 1.7. In addition, we have 1.7*100*5.4 in where we multiply 1.7 and 100, then by 5.4
Answer:
468
Step-by-step explanation:
831-x would be the equation to find the amount of peanut butter cookies. You'd plug this into the equation to find the amount of cookies in relation to money meaning your equation is 1.5x+1.65(831-x)=1316.7. You then simplify and solve to find 468
