The total amount y (in dollars) in your savings account after buying x video games is represented by y= 90-10x. You have $40 in your account after buying video games. How many video games did you buy?

Answers

Answer 1

5 video games bought.

Explanation:

Step one) identify all variables.

> y = money in bank acc AFTER buying (x) video games.

Step two) y = $40

Step three) substitute

> 40 = 90 - 10x.

Step Four) solve for x

> subtract 90 both sides.

-50 = -10x

DIVIDE by -10 on both sides ( to isolated x)

This equals 5 = x

x is number of video games bought meaning >> 5 video games bought

Write this equation in standard form: (4, -1) m = 3

Answers

Standard form looks like this: Ax + By = C.

y - (-1) = 3(x - 4)

y + 1 = 3x - 12

y = 3x - 12 - 1

y = 3x + 13

Move 13 to left side and y to right side.

-13 = 3x - y

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]

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.
