What 2 numbers have a product of 60?

60 = 1 x 60, 2 x 30, 3 x 20, 4 x 15, 5 x 12, or 6 x 10.

How do you estimate products and quotients?

Students learn to estimate a product or quotient by first rounding each number to one non-zero digit. For example, to estimate 8,291 x 27, first round 8,291 down to 8,000, and round 27 up to 30, then multiply 8,000 x 30 to get 240,000.

How do you find an estimate in statistics?

The minimum sample size n needed to estimate the population mean (μ ) is calculated using the formula: n=(Zα2σE)2 n = ( Z α 2 σ E ) 2 . (Zα2σE)2 ( Z α 2 σ E ) 2 . The minimum sample size n needed to estimate the population proportion (p ) is calculated using the formula: n=p′q′(Zα2E)2 n = p ′ q ′ ( Z α 2 E ) 2 .

What is it called to find an approximate value for a number?

To find an approximate value for a number is called estimating. – Approximate is an estimation of a number or rounding a number to its nearest place value.

What is the difference between calculate and count?

  1. From the Home screen, tap the Apps icon (in the QuickTap bar) > the Apps tab (if necessary) > Tools folder > Calculator .
  2. Tap the calculator keys to enter numbers and arithmetic operators on the calculator’s display, just like you would use a normal calculator.

What is the formula to find percentage?

1. How to calculate percentage of a number. Use the percentage formula: P% * X = Y

  1. Convert the problem to an equation using the percentage formula: P% * X = Y.
  2. P is 10%, X is 150, so the equation is 10% * 150 = Y.
  3. Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
