Answer:
16 times
Step-by-step explanation:
Since he has a 4-gallon aquarium and a 1-quart container, and since there are 4 quarts in every gallon, he'll need to fill the aquarium with the container full 16 times because for every gallon, he'll need to fill the aquarium 4 times. This is the equation:
4*4=16 times

GE = 26
Step-by-step explanation:
OP = 16 + 9 = 25
PE - OG = 7
Using Pythagorean theorem,
(GE)^2 = (OP)^2 + (PE - OG)^2
=(25)^2 + (7)^2
= 625 + 49
= 674
or
GE = √674 = 25.96 or 26

PLEASE HELP! urgent! Write the equation of a line in a slope-intercept form and standard form
Answer:
[tex]y = \frac{3}{4}x -3[/tex] --- Slope intercept
[tex]4y - 3x =- 12[/tex] --- Standard form
Step-by-step explanation:
Given
The attached linear graph
Required
The equation
Select any two points on the line
[tex](x_1,y_1) = (0,-3)[/tex]
[tex](x_2,y_2) = (4,0)[/tex]
Next, calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{0 --3}{4 - 0}[/tex]
[tex]m = \frac{3}{4}[/tex]
The slope intercept is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
[tex]y = \frac{3}{4}(x - 0) -3[/tex]
[tex]y = \frac{3}{4}(x) -3[/tex]
[tex]y = \frac{3}{4}x -3[/tex]
Multiply through bu 4
[tex]4y = 3x - 12[/tex]
Subtract 3x from both sides
[tex]4y - 3x =- 12[/tex] --- Standard form

Jamie has a $15 iTunes gift card. Songs cost $0.75 and she wants to keep $5 on the
card. How many songs can she download?
a.
Write and solve the inequality that represents Jamie's situation.
b.
Use your inequality to decide how many songs Jamie can download.
Answer:
13
Step-by-step explanation:
starting equation is 15=0.75(x)+5.
You have to have the numbers on one side so...
15-5=10, and 5-5=0.
now, our equation is 10=0.75(x).
we are looking for x, so....
10/.75= 13 and 1/3.
since there is no such thing as a third of a song, 13 would be our number.

Shirts are 5% off. The original price of one shirt is $15. What is the total cost, in dollars, of a shirt at the sale price, including a 10% sales tax
Answer:
$15.75
Step-by-step explanation:
[tex]\frac{y}{15} :\frac{5}{100}[/tex]
y × 100 = 5 × 15
100y = 75
100y ÷ 100 = 75 ÷ 100
y = 0.75
$15 - $0.75
$14.25
[tex]\frac{y}{15} :\frac{10}{100}[/tex]
y × 100 = 10 × 15
100y = 150
100y ÷ 100 = 150 ÷ 100
y = 1.5
$14.25 + $1.50
$15.75

Answer:
G is true is out divide 1/7 by 2 out get 1/14
H is false the product is always 1
I is false all numbers have a reciprocal besides 0
Answer:
g. True
h. False
i. False
Step-by-step explanation:
g.
[tex]\frac{1}{14}[/tex] is half of [tex]\frac{1}{7}[/tex]
This would be true because half of a number can be found by multiplying by [tex]\frac{1}{2}[/tex]
If you multiplied [tex]\frac{1}{7} * \frac{1}{2}[/tex]
The numerator is 1 * 1 which is 1
And then the denominator is 7 * 2 which is 14
That would give you [tex]\frac{1}{14}[/tex]
h.
The products of two reciprocals is 0
This is not true
Reason being, reciprocals are just the number flipped. If you times the number by itself, you don't get 0, you get 1.
Ex: [tex]\frac{2}{8}[/tex]
Its reciprocal is [tex]\frac{8}{2}[/tex]
So multiply them together
[tex]\frac{2}{8}* \frac{8}{2}[/tex]
2 * 8 = 16
8 * 2 = 16
[tex]\frac{16}{16} = 1[/tex]
i.
A whole number does not have a reciprocal
This is incorrect. If you think about it, a whole number is just the number, over 1
Ex: [tex]\frac{6}{1}[/tex]
This is still a whole number even though its written in fraction form because if you divide 6 by 1, your still going to get 6.
If you an write it as a fraction, it has a reciprocal.
The reciprocal in this case would be [tex]\frac{1}{6}[/tex]
I hope this helps, don't be afraid to reach out with any further questions!
PLSSSS HELLPPPPP!!!
Answer: B, D, and F
Step-by-step explanation:
Hi, so for this question, the phone bill is in an equation. Before doing this problem, make sure to understand what the 2 and 56 mean. The problem says that c is the monthly charge, and m is the number of minutes. This means that 2 is the number of dollars required to pay when you use the phone for one minute. So 2 dollars per minute. The 56 is basically the fee that is just charged for using the phone bill. Meaning that even if you don't use the phone at all, you will still need to pay 56 dollars.
By understanding those info, it should be easier to answer.
For A, it is not correct. if you look, although 2*4 is 8 dollars, but you need to add 56 for the monthly bill. (I think when they say 'your bill' they mean the monthly bill).
For B, it is correct. Like I said before, the 56 dollars is there no matter how long you use the phone.
For C, it is not correct. This isn't hard to understand since if B is correct, C is probably not, and vise versa. And the 56 dollars is missing.
For D, it is correct. As I said before, the 2 represents the amount of dollars for one minute.
For E, it is not correct. (Contradicts the previous answer and each minute costs 2 dollars).
For F, it is correct. When you use 2 minutes, the equation is 2*2+56 which is 60 dollars.
Hopefully this helps!

Answer:
( [tex]-\infty[/tex], 0) and (8, [tex]\infty[/tex])
Step-by-step explanation:
Curve is concave downward when the second derivative is negative.
y' = [tex]\frac{x^{2} }{x^{2} -x+4}[/tex] , by the Fundamental Theorem of Calculus
y'' = [tex]\frac{-x^2+8x}{\left(x^2-x+4\right)^2}[/tex] , which has a denominator that is always positive. The numerator [tex]-x^2+8x[/tex] is negative when x > 0 and when x < 8. So that is when y'' is negative, and consequently when the curve y is concave down.

In a survey of randomly selected 3,900 family-owned businesses with revenues exceeding $1 million a year, it was found that 1,911 of them had no strategic business plan. a) Use a 90% confidence interval to estimate the proportion of family-owned businesses without strategic business plans. Give an interpretation of this interval. (5 Points) b) Would a 99% confidence interval be wider or narrower than the one you calculated in part (a)
Answer:
a) The 90% confidence interval to estimate the proportion of family-owned businesses without strategic business plans is (0.4768, 0.5032). This means that we are 90% sure that the true proportion of all family-owned businesses without strategic business plans is between these two values.
b) Wider
Step-by-step explanation:
Question a:
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 z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
In a survey of randomly selected 3,900 family-owned businesses with revenues exceeding $1 million a year, it was found that 1,911 of them had no strategic business plan.
This means that [tex]n = 3900, \pi = \frac{1911}{3900} = 0.49[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.49 - 1.645\sqrt{\frac{0.49*0.51}{3900}} = 0.4768[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.49 + 1.645\sqrt{\frac{0.49*0.51}{3900}} = 0.5032[/tex]
The 90% confidence interval to estimate the proportion of family-owned businesses without strategic business plans is (0.4768, 0.5032). This means that we are 90% sure that the true proportion of all family-owned businesses without strategic business plans is between these two values.
Question b:
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
The higher the confidence level, the higher the value of z, thus the higher the margin of error and the interval is wider. Thus, a 99% confidence interval is wider than a 90% confidence interval.

5. Jon Metcalf signed a 253-day simple interest note for $7700 with a bank that uses exact interest. If the rate is 10 3/4% find the maturity value.
Answer:
8281.72
Step-by-step explanation:
Given:
Principal, P = 7700
Rate, r = 10 3/4 % = 43/4 % = 0.1075
Time, t = 253 days = 253/ 360
Using the relation :
A = P(1 + rt)
A = maturity value
A = 7700(1 + 0.1075*253/360)
A = 7700(1 + 0.0755486)
A = 7700(1.0755486)
A = 8281.7243
A = 8281.72

Suppose you save $1 the first day of a month, $4 the second day, $16 the third day, and so on. That is, each day you save four times as much as you did the day before. What will you put aside for savings on the seventh day of the month?
Answer:
$ 4096 on the 7th day
Step-by-step explanation:
From the amount earned for the first 3 days it's 1 , 4 , 16 , .... We realize it increases exponentially.
So therefore:
Day 1 =4⁰
Day 2=4¹
Day 3=4²
Day 4=4³
Day 5=4⁴
Day 6=4⁵
Day 7=4⁶
Therefore on day 7 he saves 4⁶ which is $4096
