40 ounces is equal to how many pounds? (1pound = 16 ounces)
Answers
ANSWER
\(2.5\text{ pounds}\)EXPLANATION
To find the answer, we have to apply proportions:
\(\begin{gathered} 1\text{ pound = 16 ounces} \\ x\text{ pounds = 40 ounces} \end{gathered}\)Now, cross-multiply:
\(\begin{gathered} x\cdot16=1\cdot40 \\ \Rightarrow x=\frac{40}{16} \\ x=2.5 \end{gathered}\)Therefore, 40 ounces is equal to 2.5 pounds.

Let f be a function defined for t ≥ 0. Then the integral ℒ{f(t)} = [infinity] e−stf(t) dt 0 is said to be the Laplace transform of f, provided that the integral converges. to find ℒ{f(t)}. (Write your answer as a function of s.) f(t) = cos(t), 0 ≤ t < π 0, t ≥ π
Answers
Answer:
L(f(t)) = \(2 \frac{e^{-s} }{s} - \frac{1}{s}\)
Step-by-step explanation:
let f be a function defined for t ≥ 0
we can write the function f(t) in terms of unit function as follows
f(t) = 2 u,(t) - 1 where
0≤ t < 1
f(t) = (2 * 0) -1 = -1
when t ≥ 1
f(t) = (2*1 )- 1 = 1
Now the Laplace transform L(F(T)) = 2L( u, (t) ) - L(1) --------equation 1
this is because L(u,(t)) = \(\frac{e^{-cs} }{s}\)
c = 1 hence L(1) = 1/s
back to equation 1
L(f(t)) = 2 \(\frac{e^{-cs} }{s}\) - 1/s laplace transform
also L(u(t) ) = \(\frac{e^{-s} }{s}\)
At a nearby frozen yogurt shop, the mean cost of a pint of frozen yogurt is $1.50 with a standard deviation of $0.10. Assuming the data is normally distributed, approximately what percent of customers are willing to pay between $1.30 and $1.70 for a pint of frozen yogurt?
a) 99.7%.
b) 95%.
c) 34%.
d) 68%.
Answers
$1.30 and $1.70 is two standard deviations away from the mean on both sides of the mean, and the empirical rule for normal distribution tells us that approximately 95 percent of the data are within two standard deviations of the mean. Hence, option B is the right choice.
What is a normal distribution?Data in a normal distribution is symmetrically distributed and has no skew. When displayed on a graph, the data has the shape of a bell, with most values clustering in a central region and tapering off as they go away from the center.
Because of their structure, normal distributions are sometimes known as Gaussian distributions or bell curves.
What is the empirical rule for a normal distribution?The empirical rule, often known as the 68-95-99.7 rule, indicates where the majority of your values fall in a normal distribution:
Approximately 68 percent of data are within one standard deviation of the mean.Approximately 95 percent of the data are within two standard deviations of the mean.Approximately 99.7 percent of data are within three standard deviations of the mean.How to solve the given question?In the question, we are given that at a nearby frozen yogurt shop, the mean cost of a pint of frozen yogurt is $1.50 with a standard deviation of $0.10.
We are asked that assuming the data is normally distributed, approximately what percent of customers are willing to pay between $1.30 and $1.70 for a pint of frozen yogurt.
Following the empirical rule for a normal distribution, we need to check how many standard deviations from the mean are at $1.30 and $1.70.
$1.30 = $1.50 - 2($0.10)
and $1.70 = $1.50 + 2(0.10).
Thus, $1.30 and $1.70 is two standard deviations away from the mean on both sides of the mean, and the empirical rule for normal distribution tells us that approximately 95 percent of the data are within two standard deviations of the mean. Hence, option B is the right choice.

In a public opinion survey, 80 out of a sample of 100 high-income voters and 55 out of a sample of 80 low-income voters supported the introduction of a new national security tax.
a/ Estimate, with 95% confidence level, the true proportion of low-income people who will vote for the introduction of the tax.
b/ Can we conclude at the 5% level of significance that the proportion of high-income voters favoring the new security tax is 10% higher than that of low-income voters?
Answers
The confidence interval of the true proportion of low income people who will vote for the introduction of the tax is
Yes, we can conclude that at the 5% level of significance, the proportion of high income voters favoring the new security tax is 10% higher than that of low income voters using Test of Significance for Difference of Proportions.
What is confidence interval?
A confidence interval is the mean of your estimate plus and minus the variation in that estimate.
Proportion of high-income people who will vote for the introduction of the tax = p1 = \(\frac{80}{100} = \frac{4}{5}\)\(= 0.8\)
Proportion of low-income people who will vote for the introduction of the tax = p2 = \(\frac{55}{80} = \frac{11}{16}\) \(= 0.6875\)
95% confidence interval of the true proportion of low income people who will vote for the introduction of the tax -
Upper confidence interval -
\(= p + 1.96 \sqrt{pq/n}\)
\(=0.6875 + 1.96 \sqrt{(0.6875)(1-0.6875)/80} \\= 0.6875 + 1.96 \sqrt{0.00268} \\=0.789\)
Lower confidence interval -
\(= p - 1.96 \sqrt{pq/n}\)
\(=0.6875 - 1.96 \sqrt{(0.6875)(1-0.6875)/80} \\= 0.6875 - 1.96 \sqrt{0.00268} \\=0.586\)
What is Test of Significance for Difference of Proportions?Test of Significance for Difference of Proportions is used when we want to compare two distinct populations with respect to the prevalence of a certain attribute, say A, among their members.
n1 = 100
X1 = 80
p1 = 0.8
n2 = 80
X2 = 55
p2 = 0.6875
H0: the proportion of high-income voters favoring the new security tax is 10% higher than that of low-income voters.(P1 - P2 = 0.1)
H1: the proportion of high-income voters favoring the new security tax isn't 10% higher than that of low-income voters. (P1 - P2 != 0.1)
\(z = \frac{(p1 - p2) - (P1 -P2)}{(\frac{X1+X2}{n1+n2})(1-\frac{X1+X2}{n1+n2})(\frac{1}{n1}+\frac{1}{n2} ) }\)
\(z = \frac{(0.8 - 0.6875)- 0.1}{\sqrt{0.75*0.25*0.0225} } \\\\z = \frac{0.0125}{0.0649} \\\\z = 0.1926\)
Since z = 0.1926 < 1.96, null hypothesis cannot be rejected. Thus, the proportion of high-income voters favoring the new security tax is 10% higher than that of low-income voters.

Malcolm has $50 gift card to a local car wash and order is the ultimate car wash each visit is $8.95
Answers
The amount cheaper is the car washes Malcolm orders than the car washes Martha's order is $13.
The correct answer choice is option B.
How much cheaper is the car washes Malcolm orders than the car washes Martha's order?Malcolm's gift card = $50.
Cost Malcolm's car wash per visit = $7
Martha's gift card = $180
Cost Martha's car wash per visit = Difference between gift card balance of first and second visit
= $180 - $160
= $20
How cheap is the car washes Malcolm orders than the car washes Martha's order = $20 - $7
= $13
Therefore, Malcolm's car wash is cheaper than Martha's car wash by $13

The circumference of the cylinder below is 6 cm and the height is 8 cm. What is the curved surface area of the cylinder? If your answer is a decimal, give it to 1 d.p. circumference = 6 cm
8 cm
Answers
The curved surface area of the cylinder is 48.06 cm².
The circumference of a cylinder is given by the formula:
C = 2πr
where C is the circumference and r is the radius of the base.
In this case, the given circumference is 6 cm.
So, 6 = 2πr
r = 6 / (2π)
r ≈ 0.955 cm
Now, the curved surface area (CSA) of the cylinder using the formula:
CSA = 2πrh
Given the height as 8 cm, we can substitute the values into the formula:
CSA = 2π(0.955 cm)(8 cm)
CSA ≈ 48.06 cm²
Therefore, the curved surface area of the cylinder is 48.06 cm².

For each ordered pair (x, y), determine whether it is a solution to the inequality y≤0.
(8,-43)
(4.-22)
(-3,25)
(-7,45)
Is it a solution?
Answers
Answer:
(8,-43)
(4,-22)
Step-by-step explanation:
In order for the ordered pair to be a solution of the inequality, you must be able to plug in the y-value of the ordered pair and it must be less than or equal to 0.
For example:
(4,-22)
x=4 ; y=-22
Plug y into the inequality
y≤0
-22≤0
Since the statement is true, I know that (4,-22) must be a solution to the inequality.
Another way to solve this problem is by graphing. If an ordered pair is in the shaded region, it is a solution to the inequality. Attached is a graph of both the inequality and ordered pairs plotted.
If this answer helped you, please leave a thanks or a Brainliest!!!
Have a GREAT day!!!
Answer:
Step-by-step explanation:
To determine whether each ordered pair is a solution to the inequality y ≤ 0, we need to check if the y-coordinate of each pair is less than or equal to zero.
Let's check each ordered pair:
(8, -43):
The y-coordinate is -43. Since -43 is less than zero, this ordered pair is a solution to the inequality y ≤ 0.
(4, -22):
The y-coordinate is -22. Since -22 is less than zero, this ordered pair is a solution to the inequality y ≤ 0.
(-3, 25):
The y-coordinate is 25. Since 25 is greater than zero, this ordered pair is not a solution to the inequality y ≤ 0.
(-7, 45):
The y-coordinate is 45. Since 45 is greater than zero, this ordered pair is not a solution to the inequality y ≤ 0.
So, the solutions to the inequality y ≤ 0 are:
(8, -43) and (4, -22).

How to solve an equation?An equation is an expression that can be used to show the relationship between two or more numbers and variables using mathematical operators.
The area of a figure is the amount of space it occupies in its two dimensional state.
The length of an arc with an angle of Ф is given by:
Length of arc = (Ф/360) * (π * diameter)
The diameter is 16 cm and intercepted arc length is 6 cm, hence:
Length of arc = (Ф/360) * (π * diameter)
6 = (Ф/360) * (π * 16)
Ф = 42.97°
Ф = 42.97° * π/180 = 0.75 radian

What is a parabola?A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line.
According to the given problem,
y = (x - 5)(50 - 2x)
⇒ y + (-(x - 5)(50 - 2x) = (x - 5)(50 - 2x) + (-(x - 5)(50 - 2x)
⇒ y - (x - 5)(50 - 2x) = (x - 5)(50 - 2x) - (x - 5)(50 - 2x)
⇒ y - (x - 5)(-2x + 50) = 0
⇒ y - (-x *2x + x*50 + 5*2x -5*50) = 0
⇒ y - ( -2x² + 50x + 10x - 250) = 0
⇒ y - ( - 2x² + 60x - 250 ) = 0
⇒ y + 2x² - 60x + 250 = 0
⇒ 2x² -60x + y + 250 = 0
⇒ ( 2x² - 60x ) + y + 250 = 0
⇒ 2 ( x² - \(\frac{60}{2}\)x) + y + 250 = 0
⇒ 2 ( x² - \(\frac{2^{2} *3*5}{2}\)x) + y + 250 = 0
⇒ 2 ( x² - 30x ) + y + 250 = 0
⇒ 2( x² + 2(-15)x + 225 -225 +y + 250 = 0
⇒ 2( x - 15 )² + 2(-225) + y + 250 = 0
⇒ 2( x - 15 )² + y = -2(-225) - 250
⇒ 2( x - 15 )² + y = 450 - 250
⇒ 2( x - 15 )² + y = 200
⇒ y = -2( x - 15 )² + 200
This equation is in the form of y = a(x - h)² + k where the vertex of the parabola is (h , k).
Therefore the vertex of the parabola is at (15 , 200)
Hence, we can conclude that Sofie will maximum profit of $200 if she sells a scarf at 15$ and will make the least profit if she sells the scarf at $5 or less.
