The total amount that would be spent on all the activities is  $1605.40.

<h3>What is the total amount?</h3>

The total amount that would be spent on movies = (14/25) x 1200 x 1.55  = $1041.60

The total amount that would be spent on planetarium tickets = (7/25) x 1200 x 1.05 =352.80

The total amount that would be spent on backstage passes = (4/25) x 1200 x 1.10 =211.20

Total amount = 211.20 + 352.80 +  $1041.60 = $1605.40

Answer:

(1) IT MAKES IT EASIER TO UNDERSTAND.

(2) IT HELPS TO ARRIVE AT THE POSSIBLE ROOT CAUSE AND OUTCOME.

(3) IT SHOWS RELATIONSHIP BETWEEN FACTORS.

SITUATION IN LIFE

When Determining the Relationship between my height and my weight.

BMI=WEIGHT/HEIGHT*HEIGHT.

BMI is the dependent variable

Weight and height are independent variables.

Step-by-step explanation: Mathematical representation of data or information is a very important strategy applied to solve certain Complex problems.

Mathematical representation helps to make Complex data or information easily understood,it helps one to derive the possible root cause and outcomes of problems,it also shows Relationship between various treatments or variables or drugs applied in solving problems example in treatment of Diseases.

BMI(BODY MASS INDEX) is a life situation where I have used Mathematical representation to solve, it used to show how your height and weight is related.

Independent variables are variables that do not cause any changes t other variables when altered.

Dependent variables are variables which can cause change in a situation when altered.

In this case BMI depends on The weight and height of a person, while the Weight and height of a person are independent on the BMI.

Suppose that the probability that a child living in an urban area in the United States is obese is 20%. If a social worker sees
Levart [38]

Answer:

The probability the event that none of them are obese is 0.0352.

Step-by-step explanation:

<h3>Binomial distribution:</h3>

A discrete random variable X having to the set {0,1,2,3....,n} as the spectrum, is said to have binomial distribution with parameters n= the number of trial, and p= probability of successes on an individual trial , if the p.m.f of X is given by,

P(X=x)=\left(\begin{array}{c}n\\x\end{array}\right) p^x(1-p)^{n-x} for x=0,1,2,...,n

                =0                               elsewhere.

where 0<p<1 and  n an positive integer,

Given that,

The probability of the event that a child living in an urban area in the united state is obese is 20%.

n=Number of children = 15, p= 20%= 0.20.

The probability the event that none of them are obese is

=P(X=0)

=\left(\begin{array}{c}15\\0\end{array}\right) (0.20)^0(1-0.20)^{15-0}

=0.0352

A bike shop rents each of its mountain bikes for a one time $4.00 insurance charge plus $2.50 per hour create an equation that r
egoroff_w [7]

Answer:

y=2.50x+4.00

Step-by-step explanation:

Let

x -----> the number of hours

y ----> the total cost to rent a bike in dollars

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

where

m is the slope or the unit rate of the linear equation

b is the y-intercept or the initial value

In this problem we have

The unit rate or slope is equal to

m=\$2.50\ per\ hour

The y-intercept (value of y when the value of x is equal to zero) is equal to

b=\$4.00 ----> (fee charge)

substitute the values

y=2.50x+4.00
