Mathematics

wolverine [178]4 years ago
6 0

The square root of negative numbers is either "not allowed" (Case 1) or it results in imaginary roots (Case 2).

-8+ square root of -20 /24 "not allowed," Case 1

-8+ square root of -5/6 = -8 plus or minus i times sqrt(5/6)

5√6

= -8 plus or minus i times --------- (Case 2)

A data set includes 103 body temperatures of healthy adult humans for which x= 98.1 and s = 0.56.
lutik1710 [3]

Answer:

98.1, No does not contain, yes contains.

Step-by-step explanation:

Given that

sample size n =103

Sample mean = 98.1

sample std dev s = 0.56

a) the best point estimate of the mean body temperature of all healthy humans = sample mean =98.1

b) 99% confidence interval estimate of the mean body temperature of all healthy humans

We can use Z critical since sample size is large though sigma is not known

99% CI = (98.1-\frac{0.56}{\sqrt{103} },98.1+\frac{0.56}{\sqrt{103} } )\\=(98.045, 98.155)

This does not contain 98.6

This sample does not represent the population, i.e. may be biased sample.

c) CI of population mean

= populaiton mean + /- margin of error

=(98.545, 98.656)

Yes contains 98.6

Which line shows the first error in the solution?
andrew11 [14]
<h3>Answer:</h3>

The first line.

<h3>Step-by-step explanation:</h3>

If we let x represent "a number", then "a number divided by 3" is x/3. The denominator is missing on the first line.

Further, this "is 4 more than -11", so is = 4 + (-11). The constant 4 is on the wrong side of the equal sign in line 1.

_____

The solution should be ...

... x/3 = 4 + (-11)

... x = 3·(-7)

... x = -21

___

<u><em>Check</em></u>

-21 divided by 3 is -7. That is 4 more than -11.

The distance between two cities on a map is 4 inches. The actual distance between the two cities is 24 miles. What is the scale
madam [21]

The scale used to represent the distance between two cities is 1 inch= 6 miles, where the actual distance between the cities is 24 miles.

If the scale in a different map is 1 inch= 1 mile then the separation in the graph should be 24 inches.

Step-by-step explanation:

  • Given that the distance between two cities on a map is 4 inches and the original distance between these two cities are 24 miles. Hence, to find the scale is to divide them, so you get 6
  • then, 1 inch = 6 miles, to find the inches if the scale 1 inch = 1 mile, multiply it with the original distance between these two cities. Hence,  it is 24 inches
