Answer:

= 27.2727% decrease

Step-by-step explanation:

The percentage change to 2 decimal places when a price of £11 is decreased to £8 is 27.27%

Suppose a number is 'a'

Suppose another number is 'b'

We want to know how much percent of 'b' is 'a'.

Then, it is calculated as:

[tex]\dfrac{a}{b} \times 100[/tex]

(in percentage)

Given that:

Percent change shows how much percent of the initial amount is changed.

Since we're taking about 'change', so it doesn't matter whether this was a positive change or a negative change.

Percent change =  Percent that "absolute difference of 11 and 8" is of "inital price 11"

Absolute difference of 11 and 8 = [tex]|11 - 8| =3[/tex] (in euros)

Initial price is 11 euros.

Then, we get:

Percent change in price = the percent which 3 is of 11.

Let 3 is x% of 11, then we get:

[tex]x = \dfrac{3}{11} \times 100 = 27.27\overline{27}\approx 27.27[/tex]

Thus, percent change in considered price for this case is approximately 27.27%

Answer:

In the graph, a white dot means that the value does not belong to the set, while the colored dot means that the value does belong.

Let's analyze each statement (from top to bottom)

1)The x-axis represents the number of hours, and the y-axis the charge.

Then let's find x = 2.

You can see that there is a colored dot at y = $3, and a white dot at y = $5.

Then the price for exactly two hours is $3, not $5.

Then this first statement is wrong.

2) You can assume that 20 minutes is in between x = 0 and x =1, then from that point, you can see that the equivalent value of y is $1. Then the individuals who park only for 20 minutes will be charged with $1,

This statement is wrong.

3) 1 hour and 15 minutes is in between 1 and 2 hours.

And as you can see, for 1 < x ≤ 2, the price is $3. Then this statement is correct.

4) Here we have x > 4.

In the graph you can see that all values of x > 4 are mapped into the black part of the graph, which is equivalent to the maximum charge of $9.

Then this statement is correct.

Answer:

I don't know if my answer is correct but I would say $12.65

Step-by-step explanation:

The reason I would say this is because 13 percent off 14.55 is 1.8915 and I rounded that to 1.89 and subtracted that from 14.44 to get $12.65

Answer:

Step-by-step explanation:

A die is known to have 6 faces. If n die are rolled, the total number of outcomes or sample space is expressed as;

n(S) = [tex]6^n[/tex] where;

n is the total number of dies

If two balanced die are rolled, the total number of sample space will be;

n(S) = [tex]6^2 = 36[/tex]

Since we want to to determine the probability that the sum of the dice is 11, the possible outcome or event will be;

n(E) = {(5, 6), (6,5)}

N(E) = 2

Probability = Possible outcome/Total outcome

Probability that the sum of the dice is 11 = n(E)/n(S)

Probability that the sum of the dice is 11 = 2/36

Probability that the sum of the dice is 11 = 1/18

Answer:

The Margin of Error E [tex]\simeq[/tex] 4.1 %

Step-by-step explanation:

Given that:

The sample size = 579

The sample proportion [tex]\hat p = 55\%[/tex] = 0.55

From the confidence interval of 95%

The level of significance ∝ = 1 - C.I = 1 - 0.95 = 0.05

The critical value of [tex]Z_{\alpha/2 } = Z_{0.025} = 1.96[/tex]

Thus;

The Margin of Error E = [tex]Z_{\alpha/2 } \times \sqrt{{\dfrac {\hat p ( 1 - \hat p }{n}}[/tex]

The Margin of Error E = [tex]1.96 \times \sqrt{{\dfrac {0.55 ( 1 - 0.55) }{579}}[/tex]

The Margin of Error E = [tex]1.96 \times \sqrt{{\dfrac {0.55 ( 0.45 )}{579}}[/tex]

The Margin of Error E = [tex]1.96 \times \sqrt{{\dfrac {0.2475}{579}}[/tex]

The Margin of Error E = [tex]1.96 \times \sqrt{{4.2746114 \times 10^{-4}}[/tex]

The Margin of Error E = [tex]1.96 \times .020675[/tex]

The Margin of Error E = 0.040523

The Margin of Error E [tex]\simeq[/tex] 0.041

The Margin of Error E [tex]\simeq[/tex] 4.1%

X = -10

Explanation:

-1.1x + 8.1x + 38 = -32

Combine like terms : -1.1x + 8.1x

7x + 38 = -32

Subtract 38

7x = -70

Divide by 7

7x = -70/7

Answer:

x = -10

Answer:

x= -10

Step-by-step explanation:

1. start by subtracting 38 from both sides

-1.1x+8.1x+ (38-38)= (-38-32)

2. Solve

-1.1x+8.1x= -70

3. Add the x- values

7x=-70

4. Solve

x= -10
