Answer:

1) $\sqrt{569}$ 2) 8 3) 0.8 4) $\sqrt[10]{61}$

Step-by-step explanation:

The equation for pythagoream theorem is

a^2 + b^2 = c^2 (the caret "^" represents exponents)

A = a side length

B = another side length

C = the hypotnuse which is the slanted side of the right triangle.

To solve these problems plug in the known values into the equation then solve.

If one costs £0.05, find the cost of 100

Rina8888 [55]

This is quite simple once you understand.
Since 100 is a round number all you must do is move the 0.05 up 2 zeros.
You get the zeros from the hundreds btw.

0.05 x 100 = 5
So the answer is £5

Suppose that you want to estimate average income in a population. If the standard deviation of income in the population is $1,00

Alik [6]

Answer:

2401

Step-by-step explanation:

Given that we want to estimate average income in a population.

The standard deviation of income in the population is $1,000

We want confidence interval around our estimate to be +/- $40

i.e Margin of error = 40

We know that margin of error = Std error * Z critical for 95%

i.e. $40 = 1.96 * std error$

Std error = $\frac{std dev}{\sqrt{n} } \\=\frac{1000}{\sqrt{n} }$

Together we get

$40=1.96(\frac{1000}{\sqrt{n} } )\\\sqrt{n} =\frac{1000*1.96}{40} \\=49\\n=2401\\$

Answer:

A"fishbone" diagram

Step-by-step explanation:

A"fishbone" diagram, may help to determine potential causes of an issue and organise concepts into valuable groups of brain storming. A depiction of the fishbone is a graphical way of looking at causes and effects.

It's a more organised solution than other brain storming tools that cause problems. The issue or effect is shown on the fish's head or mouth.
