I believe that it deals with standard deviations you need to look at a graph of the standard deviation.

The 95\% confidence interval for the population mean is \left( {6.93,11.45}\right) means that there are 95\% chances of the population mean lies in the interval.

Further Explanation:

Explanation:

The formula for confidence interval can be expressed as follows,

\boxed{{\text{Confidence interval}}=\left( {\overline X  \pm ME} \right)}

ME represents the Margin of Error.

The confidence interval has two limits.

(1). Upper Limit

(2). Lower Limit

The upper limit can be calculated as follows,

{\text{Upper limit}}=\left( {X + ME}\right)

The lower limit can be calculated as follows,

{\text{Lower limit}} = \left( {X - ME}\right)

The given confidence interval is \left( {6.93,11.45}\right).

The upper limit of the confidence interval is 11.45.

The lower limit of the confidence interval is 6.93.

The 95\% confidence interval for the population mean is \left( {6.93,11.45}\right) means that there are 95\% chances of the population mean lies in the interval.

Simplify the following expression using imaginary numbers. Express your answer in a + bi form
mamaluj [8]
<h2>Answer:</h2>

0 - 17i

<h2>Step-by-step explanation:</h2>

Given expression;

i⁸⁰ + i³⁸ - i17

To express the expression in the form a+bi;

<em>i. Rewrite the expression such that it contains terms in i²</em>

(i²)⁴⁰ + (i²)¹⁹ - i17

<em>ii. Solve the result from (i) above using the identity i² = -1</em>

We know that the square root of -1 is i. i.e

\sqrt{-1} = i

<em>Squaring both sides gives</em>

<em>=> </em>(\sqrt{-1} )^{2} = i^{2}<em />

=> -1 = i²

Therefore,

i² = -1

<em>Substitute i² = -1 in step (i) above</em>

(-1)⁴⁰ + (-1)¹⁹ - i17

<em>(iii) Solve the result in (ii)</em>

We know that the when a negative number is raised to the power of an even number, the result is a positive number. If it is raised to the power of an odd number, the result is a negative number. Therefore,

(-1)⁴⁰ + (-1)¹⁹ - i17 becomes

1 + (-1) - i17

0 - i17

<em>(iv) Write the result from (iii) in the form a+bi</em>

0 - 17i

At top cruising speed, a mako shark can swim 4 kilometers in 1/10 hour. A blue whale can swim 5 kilometers in 1/4 an hour which
Pie

Answer: Mako shark

Step-by-step explanation:

We will calculate the speed of the sharks to know which is faster.

A mako shark can swim 4 kilometers in 1/10 hour.

Speed = Distance/Time

= 4/(1/10)

= 40km/hour

A blue whale can swim 5 kilometers in 1/4 an hour.

This shows that the Mako shark is faster as it swims at rate of 40km/hour and the blue whale swims at 5km/hour. It's faster by 35km.

= 40km - 5km

= 35km
