The average amount of time to finish this quiz is 26 minutes with a standard deviation of 1.2 minutes. What is the probability t
boyakko [2]

Answer:

What is the probability that you will finish this quiz in 23.84 minutes or less?

0.03593

Write your answer as a percentage with 2 decimals

= 3.59%

Step-by-step explanation:

The z score formula is given as:

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

Mean = 26 minutes

Standard deviation = 1.2 minutes.

The probability that you will finish this quiz in 23.84 minutes or less(≤) is calculated as:

z = (x-μ)/σ

z = 23.84 - 26/1.2

z = -1.8

Probability value from Z-Table:

P(x ≤ 23.84) = 0.03593

Converting to percentage

0.03593 × 100

= 3.593

Approximately to 2 decimal places = 3.59%

Learning Task 1: Read and analyze each problem carefully. Write your final answer in your notebook based on the given questions
solmaris [256]

Solving the given problems using the appropriate arithmetic operation such as multiplication, divison and addition, the answers are :

  • <em>4</em><em> </em><em>people</em><em> </em>
  • <em>1000</em><em> </em><em>ml</em><em> </em>
  • <em>$</em><em>1960</em>

Total size of pizza = 2 \frac{2}{3} = \frac{8}{3}

Number of pizzas gotten by each person = \frac{2}{3

<u>Number of people sharing pizza</u> :

\frac{8}{3} \div \frac{2}{3} = \frac{8}{3} \times \frac{3}{2} = 4 \: people

2.)

  • <em>Volume bottle = 600 ml</em>

  • Fraction of water = \frac{3}{5}

Volume of full bottle = \frac{3}{5} \times n =  600 = \frac{3n}{5} = 600

Volume of full bottle = \frac{3n}{3000}

Volume of full bottle = n = \frac{3000}{3} = 1000 ml

3.)

  • Amount left = Php. 980
  • Fraction spent = \frac{4}{8}

<em>Let the monthly salary = m</em>

Fraction left = 1 - \frac{4}{8} =  \frac{4}{8} = \frac{1}{2}

Hence,

\frac{1}{2} \times m = 980

\frac{m}{2} = 980

m = 980 \times 2 = 1960

Therefore, Joel's monthly salary is $1960
