saw5 [17]

Answer:

50% of all students scored more than 48 marks.

Step-by-step explanation:

1) The baseline of the box, in a box plot is the first quartile, the line in the middle is the median or Q2 and the last line (or top line) is the third quartile. Namely,

Q_{1}=30, Q_{2}=48 \:and\:Q_{3}=70

2) The Question says "nobody took 30, 48 or 70 as their grades. But 120 students gained less than 70", i.e. 120 are within the 75% of the sample.

3) If Q_{2}=48 then 50% of the students scored more than 48. And 50% of the students scored less than 48. That is also known as the Median.

So 50%, the half of all students scored more than 48 marks.

igomit [66]

Answer:

Interest= $423.59

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $6,000

Number of periods (n)= 3 years

Interest rate (i)= 2.3% = 0.023

<u>To calculate the Future Value, we need to use the following formula:</u>

FV= PV*(1+i)^n

FV= 6,000*(1.023^3)

FV= $6,423.59

<u>Now, the interest earned:</u>

<u />

Interest= 6,423.59 - 6,000

Interest= $423.59

James bought a cake that weighs 3 and 1 over 4 pounds. How many ounces does the cake weigh? Show your work. (5 points)
kolezko [41]

The weight of James cake in ounces is 52 ounces and the Pint of water dispensed in 20 seconds is 24 pints

<h3>Weight</h3>

  • Weight of cake = 3 1/4 pounds

1 pound = 16 ounces

Number of ounces the cake weigh = 3 1/4 pounds × 16 ounces

= 13/4 × 16

= (208) / 4

= 52 ounces

  • Water dispensed per second = 0.15 gallons
  • Number of seconds = 20 seconds

1 gallon = 4 quarts

0.15 gallon = 0.6 quarts

1 quart = 2 pints

0.6 quart = 1.2 pints

Pint of water dispensed in 20 seconds = 1.2 × 20

= 24 pints of water
