Answer:

They are parallel

Step-by-step explanation:

They both start with y=2/3x so you know the slope is the same. The +4 and -1 are just the intercepts

Answer:

6 and 7

Step-by-step explanation:

You first want to find the factors of 42. They are:

Answer:

41 pages of notes

Step-by-step explanation:

Since he took 1 page of notes for each hour, and attended 33 hours of class, this will add 33 pages of notes to his notebook.

To find the total, add 8 to this, because he already had 8 pages on his own.

33 + 8

= 41

So, he will have 41 pages of notes in his notebook

Answer:

He will have 41 pages of notes in his notebook.

Step-by-step explanation:

(33*1)+8

30*1=30

3*1=3

30+3=33

33+8

Answer:

{3,6,7,10}

Step-by-step explanation:

2/3(3)+1=3

2/3(6)+1=5

2/3(7)+1=17/3

2/3(10)+1=23/3

length = 3 + w (width)

perimeter: 66

2(3 + w + w) = 66

6 + 2w + 2w = 66

6 + 4w = 66

4w = 60

w = 15

length = 15 + 3 = 18

final answer:

length = 15 yards

width = 18 yards

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%

Step-by-step explanation:

But I divided

and my answer was 5r4

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:

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

Answer:

112°

Step-by-step explanation:

Each of the interior angles that measure 34° and mentioned there are two of them will add up to 68°.  A triangle must equal 180°.  Subtract 68 from 180 to get 112° as your final answer.

Answer:

112

Step-by-step explanation:

180-(34+34)

180-68

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".

0% probability that 3 of them have insurance

Step-by-step explanation:

For each American, there are only two possible outcomes. Either they have insurance, or they do not. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Twenty-percent (20%) of Americans have no health insurance.

This means that 80% have insurance, so [tex]p = 0.8[/tex]

Randomly sample n = 15 Americans.

This means that [tex]n = 15[/tex]

What is the probability that 3 of them have insurance? ​

This is [tex]P(X = 3)[/tex]

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{15,3}.(0.8)^{3}.(0.2)^{12} = 0[/tex]

0% probability that 3 of them have insurance

Step-by-step explanation:

Hope this helps have an amazing day!

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]
