50 POINTS *GIVEING BRAINLIEST*

Answers

60 square feet= $287.00 + $80.00

                       = $367

1 square feet= $367 / 60

                     = $6.116666667

                     = $6.12 (to 2dp) ( answer)

Answer:

60 square feet for 287 = 287/60 = 4.78 per square foot

so ur equation would be : y = 4.78x + 80

6. A recent Gallop poll showed Trump's approval rating 40% with a margin or error of 3%.
a) Find the confidence interval,
c) Does the confidence interval support that more than 50% of Americans approve of
Trump? Why or why not?

Answers

Answer:

Explained below.

Step-by-step explanation:

The (1 - α)% confidence interval for the population proportion is:

[tex]CI=\hat p\pm MOE[/tex]

Given:

[tex]\hat p=0.40\\MOE=0.03[/tex]

(a)

Compute the confidence interval as follows:

[tex]CI=\hat p\pm MOE[/tex]

     [tex]=0.40\pm0.03\\\\=(0.37, 0.43)[/tex]

(b)

Since the confidence interval consists of values less than 50%, it implies that there is not enough evidence to suggest that more than 50% of Americans approve of Trump.

How many 5-digit numbers are there in which three of the digits are 6, or two of
the digits are 9 ?

Answers

Answer:

The value  is  [tex]Z = 80[/tex]

Step-by-step explanation:

From the question we are told that

    The total  number of digit is  n = 5

     The total possible number of  6  is  k =  3

     The total possible number of  9  is  a = 2

Generally the number of way of representing a 5 digits number(i.e the number of five digit numbers ) in which 3 of the digit are 6 is mathematically represented as

       [tex]N = ^ nP_k[/tex]

Here P stands for permutation hence we are going to be making use of the permutation function in our calculators

      [tex]N = ^ 5P_3[/tex]

=>   [tex]N = 60[/tex]

Generally the number of way of representing a 5 digits number(i.e the number of five digit numbers ) in which 2 of the digit are 9 is mathematically represented as

       [tex]M = ^ nP_a[/tex]

      [tex]M = ^ 5P_2[/tex]

=>   [tex]M = 20[/tex]

Generally the number of 5-digit numbers there are in which three of the digits are 6, or two of  the digits are 9  is mathematically represented as

      [tex]Z = M + N[/tex]

=>   [tex]Z = 60 + 20[/tex]

=>   [tex]Z = 80[/tex]

Answer:

A, 38, 40

Step-by-step explanation:

a. A has to be the first graph because it starts at $ 25 and it rises as more work needs to get done

b.if you go from 50 up until you get to the line, then look left at the axis is about $38

c. C=25+s*0.25, substitute c=35 and find s

35=25+s*0.25 subtreact 25 from both sides

35-25= s*0.25

10=s*0.25 divide both sides by 0.25

10/0.25=s

40=s
