Answer:
<em>C. A Fraction whose Numerator is smaller than the denominator</em>
Step-by-step explanation:
<u><em>A proper fraction is a fraction whose numerator is smaller than its denominator.</em></u>
<u><em> An improper fraction is a fraction whose numerator is equal to or greater than its denominator. </em></u>
Example:
<em>3/4, 2/11, and 7/19 are proper fractions, while 5/2, 8/5, and 12/11 are improper fractions.</em>
Answer:Answer: Isabella buys 2 paintbrushes and 3 jars of paint.
Step-by-step explanation:
Isabella can buy together 5 paintbrushes ( p ) and jars of paint ( p ) : j + p = 5, She can`t buy 4 items ( because 4 * $0.99 = $3.96 < $4.87 ) and she also can`t buy 6 items ( 6 * $0.95 = $5.70 > $4.87 ). So: p = 5 - j. Another equation is: 0.95 * ( 5 - j ) + 0.99 j = 4.87, 4.75 - 0.95 j + 0.99 j = 4.87; 0.04 j = 0.12; j = 0.12 : 0.04; j = 3, p = 5 - 3 = 2. We can prove it: 0.95 * 2 + 0.99 * 3 = 1.90 + 2.97 = 4.87.

Answer:
<u>The correct answer is B. μ = US$87.50 and σ = US$6.50</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Number of baskets of apples picked each day by Parker = A
Mean of A = 4.5 baskets
Standard deviation = 1.3 baskets
Daily payment received by Parker = US$ 65 + US$ 5 per basket
2. What are the mean μ and standard deviation σ of Parker’s daily pay?
Let's find out the mean and standard deviation of Parker's daily pay:
Daily payment received by Parker = US$ 65 + US$ 5 per basket
Daily payment mean received by Parker = 65 + 5 * 4.5
Daily payment mean received by Parker = 87.5
Standard deviation in US$ = 1.3 * 5
Standard deviation in US$ = 6.5
<u>The correct answer is B. μ = US$87.50 and σ = US$6.50</u>
