Answer:

The change is a decrease by ~13.6%

Step-by-step explanation:

Formula:

[First Value – Second Value] ÷ [(First Value + Second Value) ÷ 2] × 100

48 - 84 ÷ 48 + 84 ÷ 2 × 100

-36 ÷ 132 ÷ 2 × 100

-0.2727272727272727 ÷ 2 × 100

-0.1363636363636364 × 100

-13.63636363636364

Or ~ 13.6

The change is a decrease by ~13.6%

Answer:

Margin of error for 90% C.I: 0.065

Margin of error for 99% C.I: 0.091

Margin of error for 95% C.I: 0.077

Step-by-step explanation:

In this question, for each student, there are only two possible outcomes. Either they use a pencil to take notes, or they do not. Students are independent of each other. So we use the binomial probability distribution to solve this question.

Binomial confidence interval:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

For this problem, we have that:

120 students, so [tex]n = 120[/tex]

90 responded favorably, so [tex]p = \frac{90}{120} = 0.75[/tex]

Margin of error for 90% CI:

Here [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}} = 1.645\sqrt{\frac{0.75*0.25}{120} = 0.065[/tex]

Margin of error for 99% CI:

Here [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.325[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}} = 2.325\sqrt{\frac{0.75*0.25}{120} = 0.091[/tex]

Margin of error for 95% CI:

Here [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}} = 1.96\sqrt{\frac{0.75*0.25}{120} = 0.077[/tex]

Answer: Margin of error for 99% CI: z=2.575 . input that into the equation and it give you .1017

final answer is 14/15

Answer:

$10 coins: 21

$20 coins: 24

Step-by-step explanation:

So we can create 2 equations where

x = number of $10 coins

y = number of $20 coins:

x + y = 45

10x + 20y = 690

we can move equation 1 around so that we can get a value of x

x = 45 - y

now we can substitute x into the second equation

10(45 - y) + 20y = 690

450 - 10y + 20y = 690

10y = 240

y = 24

Now plug in y back into the first equation

x = 45 - y

x = 45 - 24

x = 21

Answer:

The volume of water the pond will lose in 31 hours is 17.71 gallons.

Step-by-step explanation:

Given;

Rate of water leakage, R =  12 gallon of water in 23 hours

[tex]R = \frac{12 \ gallons}{23 \ hours}[/tex]

In 31 hours the volume of water leaked is calculated as;

[tex]V = \frac{12 \ gallons}{21 \ hours} \times 31 \ hours\\\\V = 17.71 \ gallons[/tex]

Therefore, the volume of water the pond will lose in 31 hours is 17.71 gallons.

Answer:

Step-by-step explanation:

Answer:   [-13, 37]

======================================================

Explanation:

The smallest x value possible is 12-25 = -13

The largest x value possible is 12+25 = 37

It might help to draw out a number line to see this.

x is between -13 and 37, including both endpoints. We can write [tex]-13 \le x \le 37[/tex]

This converts to the interval notation [-13, 37] which is the answer.

The use of square brackets is to indicate "include this endpoint".

Answer: c

Step-by-step explanation:

You can take the blank as x

so 361.2 / x = 36.12

multiply by x

361.2 = 36.12x

divide

x = 10

Answer: $2.3

Step-by-step explanation: well you need to find 10% of 23.45, so multiply .1 by 23.45.

[tex]23.45 \times 10\%[/tex]

[tex] = 23.45 \times 0.1[/tex]

[tex] = 2.345[/tex]

$2.35 is the tip amount

[tex]23.45 + 2.345[/tex]

[tex] = 25.795[/tex]

[tex] = 25.80[/tex]

$25.80 is the total bill

Answer:

The circular pizza is cheaper because you pay less money for a unit area of the pizza

Step-by-step explanation:

Step one:

given data

The dimension of the square pizza is

24 X 24 cm

The area is

= 576cm^2

Also, the dimension of the circular pizza is

DIameter = 30cm

radius = 30/2 = 15cm

The area is

= πr^2

=3.142*15^2

=706.95cm^2

Step two:

let us find the cost per area of each of the shape of the pizzas

For the square pizza the cost per area is

= 7350/576

=$12.76 per area

For the circular pizza, the cost per area is

= 7350/706.95

=$10.40 per area

Answer: I believe the scale is balanced.

Step-by-step explanation: I stated that because since the other side of the scale contained 12 marbles that were 1 pound each that would be 12 pounds and then since 4+8=12 12 pounds of marbles were also put on the other side.

Answer:

[tex]B(t) = 300(1.01)^{t}[/tex]

Step-by-step explanation:

The balance owed after t months can be given by an exponential function in the following format:

[tex]B(t) = B(0)(1+r)^{t}[/tex]

In which B(0) is the initial balance owed and r is the growth rate, as a decimal.

You owe $300 on your credit card. For every month that you fail to make a payment, your balance increases by 1%.

This means, respectively, that [tex]B(0) = 300, r = 0.01[/tex]

So

[tex]B(t) = 300(1+0.01)^{t}[/tex]

[tex]B(t) = 300(1.01)^{t}[/tex]
