Mr. Allenby spent $34 for 6 movies. If each movie is the same price, how much would he have to spend for 24 movies?
Answer: I think it $136
Step-by-step explanation:
Answer:
$136
Step-by-step explanation:
If Mr. Allenby spent $34 on 6 movies we know that each movie costed roughly $5.67
(34 / 6 = 5.666...)
Knowing this we can multiply $5.67 by 24 which equals $136
(5.666... x 24 = 136)

A number is twice the other number. The sum of four times the smaller number and three times the larger number is 10. Find the numbers.
Please teach me how to do this. I'll give 90 points.
Answer:
1 and 2
Step-by-step explanation:
Let the first number be x
Let the other number be y
x = 2y.....eqn 1
From eqn 1, the smaller number is y while the bigger number is x.
3x + 4y = 10.... eqn 2
Substitute x = 2y into eqn 2
3(2y) + 4y = 10
6y + 4y = 10
10y = 10
Divide both sides by 10
y = 10/10
y = 1
Substitute y= 1 into eqn 1
x = 2y
x = 2(1)
x = 2

A researcher wants to estimate the percentage of all adults that have used the Internet to seek pre-purchase information in the past 30 days, with an allowable sampling error (E) of 0.03 and a confidence level of 99.74%. Of secondary data indicated that 25% of all adults had used the Internet for such a purpose, what is the sample size
Answer:
The sample size is 1875.
Step-by-step explanation:
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]
Sampling error of 0.03.
This means that [tex]M = 0.03[/tex]
99.74% confidence level
So [tex]\alpha = 0.0026[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.0026}{2} = 0.9987[/tex], so [tex]Z = 3[/tex].
25% of all adults had used the Internet for such a purpose
This means that [tex]\pi = 0.25[/tex]
What is the sample size
The sample size is n. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 3\sqrt{\frac{0.25*0.75}{n}}[/tex]
[tex]0.03\sqrt{n} = 3\sqrt{0.25*0.75}[/tex]
Simplifying by 0.03 both sides
[tex]\sqrt{n} = 100\sqrt{0.25*0.75}[/tex]
[tex](\sqrt{n})^2 = (100\sqrt{0.25*0.75})^2[/tex]
[tex]n = 1875[/tex]
The sample size is 1875.

Answer:
[tex] \frac{1681}{4} [/tex]
or
[tex]105 \frac{1}{4} [/tex]
Step-by-step explanation:
[tex]10 \frac{ + 1}{ \times 4} [/tex]
10×4=40+1=41, that will be your numerator (number at the top of the fraction) and the denominator 4 will stay the same. (bottom number)
[tex] \frac{41}{4} [/tex]
the base and the height will remain the same.
Formula : base × height = Area
[tex] \frac{41}{4} \times \frac{41}{4} = \frac{1681}{16} [/tex]
16 goes into 1681 105 times remainder 1.
so as a mixed number it will be
[tex] 105 \frac{1}{4} [/tex]
