<h2>Answer:</h2>

A.) {-6, -2, 5}

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

A function f from a set A to a set B is a relation that assigns to each element x in the set A exactly one element y in the set B. The set A is the domain (also called the set of inputs) of the function. From the figure, we can see that this set is the x-coordinate of each red point. So this set is {-6, -2, 5}

Answer:

1. Precise

2.Both

3.Precise

5.Neither

Step-by-step explanation:

Accuracy is the closeness of a measured value to a standard value.

Precision is the closeness of two or more measurements to each other.

1.The norm is 45 sit-ups in a minute.The students did, 64, 69,65 and 67. Values are not accurate compared to standard value 45.

Values are precise

Answer--Precise

2. Average score is 89.5

  Scores are 89,93,91,87

  Values are precise i.e a difference of 2 from each score

  Values are accurate because the average score is 90 thus compared to      the known average score of 89.5 they are accurate.

Answer-Both

3. Yesterday temperature=89

   Tomorrow=88

    Next day=90

   Average =75

   Values are precise i.e. difference of ± 1°

   Values are not accurate compared to the average temperatures of 75 F

   Answer---Precise

5. The jar contained 568 pennies

   The 6 people guessed the numbers as

    735,209,390,300,1005, 689

  The values are not precise

  The values are not accurate

  Answer---Neither

The volume of a sphere is 5000 pi m^3 what’s the surface area of the sphere
VMariaS [17]
Volume of sphere is given by:
V=4/3πr³
the radius of the sphere will therefore be given by:
5000π=4/3πr³
solving for r we get:
r³=3750
hence
r=15.54 m
the area will therefore be:
A=4πr²
A=4π(15.54)²A=965.49π m²

If the inspection division of a county weights and measures department wants to estimate the mean amount of
Amanda [17]

If inspection department wants to estimate the mean amount with 95% confidence level with standard deviation 0.05 then it needed a sample size of 97.

Given 95% confidence level, standard deviation=0.05.

We know that margin of error is the range of values below and above the sample statistic in a confidence interval.

We assume that the values follow normal distribution. Normal distribution is a probability that is symmetric about the mean showing the data  near the mean are more frequent in occurence than data far from mean.

We know that margin of error for a confidence interval is given by:

Me=z/2* ST/\sqrt{N}

α=1-0.95=0.05

α/2=0.025

z with α/2=1.96 (using normal distribution table)

Solving for n using formula of margin of error.

n=(z/2ST/Me)^{2}

n=(1.96*0.05)^{2} /(0.01)^{2}

=96.4

By rounding off we will get 97.

Hence the sample size required will be 97.
