Answer:

457,000 is your answer to the question

Step-by-step explanation:

Answer:

The number of observations in the data set expected to be below a value of 231 is of 4793.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 195

Standard deviation = 12

The normal distribution is symmetric, which means that 50% of the observations are above the mean and 50% are below.

Proportion of observations below 231:

231 = 195 + 3*12

So 231 is three standard deviations above the mean.

Of the 50% of observations below the mean, all are below 231.

Of the 50% of observations above the mean, 99.7% are between the mean of 195 and three standard deviations above the mean(231).

So, the proportion of observations below 231 is:

[tex]P = 0.5*1 + 0.5*0.997 = 0.9985[/tex]

Out of 4800:

0.9985*4800 = 4793

The number of observations in the data set expected to be below a value of 231 is of 4793.

Answer:

The total length of Valerie’s walls is (2.5 × 4) + (21.25 × 3) + 32.

The total length of Seth’s walls is 3.5 + (22.75 × 2) + 58.

To find the expression for the perimeter of the house, add Valerie’s expression to Seth’s:

(2.5 × 4) + (21.25 × 3) + 32 + 3.5 + (22.75 × 2) + 58.

Answer:

D

Step-by-step explanation:

The mean is usually the best measure of central tendency to use when your data distribution is continuous and symmetrical, such as when your data is normally distributed.

Option (A)

Which measure of central tendency would be to compare?

Typically the trimean and trimmed mean will fall between the median and the mean, although in this case, the trimmed mean is slightly lower than the median. The geomtric mean is the lower than all measures except the mode. Measures of central tendency for the test scores.

Answer:

7c+3

Step-by-step explanation:

Answer:

your answer is gonna be "A" if you want to type 1/14 into the calculator.

The value of expression one fourteenth = A) 1 ÷ 14

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.

We need to find the expression of one fourteenth

A negative divided by a negative is positive, then;

one fourteenth = 1/14

Or

1 ÷ 14

Therefore, The value of  1 ÷ 14 = 1/14.

Answer:

16x^4

Step-by-step explanation:

first compute -2 to the 4th power, then x to the 4th power

(-2)^4= positive 16 because of parentheses and the exponent(4) is even

(x)^4 is just x^4

so multiply 16 and x^4 together and you get 16x^4

Hence, the two way frequency table is:

                  Action                 Drama                Comedy         total

Highschool  26/128=0.20          14/128=0.11           22/128=0.17     0.48      

College      20/128=0.16            28/128=0.22        18/128=0.14      0.52          

----------------------------------------------------------------------------------------------------------

total                   0.36                        0.33                     0.31                   1

Step-by-step explanation:

" When a two-way table displays percentages or ratios (called relative frequencies), instead of just frequency counts, the table is referred to as a two-way relative frequency table " .

We are given a table or data  as:

                         Action              Drama                     Comedy     Total

Highschool        26                     14                            22                 62

College              20                     28                            18                 68

------------------------------------------------------------------------------------------------------------

Total                            46                      42                           40               128

The total number of students in all the categories and classes are: 128

Hence the two way frequency table is constructed by dividing all the frequencies by the total number of students i.e. 128.

                               Action                 Drama                Comedy         total

High school      26/128=0.20          14/128=0.11           22/128=0.17     0.48      

College           20/128=0.16            28/128=0.22        18/128=0.14      0.52          

----------------------------------------------------------------------------------------------------------

Answer:

y=20x+25, this equation is linear, the rate of change is constant

Step-by-step explanation:

She starts with 25$, that doesn't change so its our constant.  Let x represent each week.  Each week she ears 20$

So, let y represent the total amount of money she has

y=20x+25, this equation is linear, the rate of change is constant

Answer:

Equation: y = 15.5x

Step-by-step explanation:

Given that:

Time earns $31 for 2 hours

$46.5 for 3 hours

$62 for 4 hours

We will find unit rate first.

Unit rate = [tex]\frac{31}{2}[/tex] = $15.5 per hour

Now,

Let,

x be the number of hours

y be the total money earned by Tim

Total earning = Per hour rate * Number of hours

y = 15.5x

Hence,

Equation: y = 15.5x

Hello there, I hope you are having a great day :) Your Question: John was swimming for an hour and a half hours at a speed of 2 miles per hour.How far did he swim? So the answer would be that 1 Hour = 2 miles and then do 1/2 hours = 2 divide 2 miles 1 and 1/2 hours = 2 + 1 Miles so 1 and 1/2 Hours = 3 miles so john swim 3 miles.

Hopefully that helps you :)
