The number of hours till Ed and Julie were 875 miles apart was 7 hours.
How to find the time ?Since Ed and Julie are traveling in opposite directions, we can think of their distances from Good Life City as two separate distances that are adding up to their total distance apart.
For Ed, his distance from Good Life City is:
= 60 t
For Julie :
= 65t
We want to know how many hours it took for their total distance to be 875 miles. So we can set up the equation:
875 = 60t + 65t
Simplifying, we get:
875 = 125t
t = 875 / 125
t = 7 hours

need help with problem 4 test stastic and p value
The p-value for this sample is approximately 0.004655 which is smaller than the significance level of 0.005. This means that we reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the population proportions are not equal.
What is the test statistic for this sample?To test the hypothesis Hₐ : p₁ ≠ p₂ at a significance level of α = 0.005, we can use the two-sample z-test for proportions, where the test statistic is given by:
z = (p₁ - p₂) / sqrt{p(1-p)(1/n₁ + 1/n₂)}
where p = (x₁ + x₂) / (n₁ + n₂) is the pooled sample proportion, x₁ and x₂ are the number of successes in the two samples, n₁ and n₂ are the sample sizes for the two samples, and p₁ and p₂ are the sample proportions for the two samples.
Plugging in the given values, we have:
p₁ = 119/687 ≈ 0.1732
p₂ = 137/577 ≈ 0.2374
n₁ = 687
n₂ = 577
p = (119 + 137) / (687 + 577) ≈ 0.202
z = (0.1735 - 0.2376) / √{0.202 * (1 - 0.202) * (1/687 + 1/577)} ≈ -2.83
The test statistic for this sample is approximately -2.83
To find the p-value for this sample, we need to find the probability of observing a test statistic as extreme as -2.83, assuming that the null hypothesis is true. Since this is a two-tailed test, we need to find the area in the tails of the standard normal distribution that corresponds to a significance level of 0.005:
α/2 = 0.005/2 = 0.0025
Using a standard normal table or a calculator, we can find that the z-score corresponding to an area of 0.0025 in the left tail of the standard normal distribution is approximately -2.81. The z-score corresponding to an area of 0.0025 in the right tail is approximately 2.81.
The p-value for this sample is the sum of the areas in the tails beyond the test statistic:
p-value = P(Z ≤ -2.83) + P(Z ≥ 2.83)
P = 0.004655

Find all points having an x-coordinate of 2 whose distance from the point (-2,-4) is 5
The two points with an x-coordinate of 2 and a distance of 5 from (-2, -4) are: (2, -4 + 2√13) and (2, -4 - 2√13)
What is distance formula?
Distance is a measurement of how far away two things or locations are, either numerically or occasionally qualitatively.
Distance formula: [tex]distance = \sqrt{((x2 - x1)^2 + (y2 - y1)^2)}[/tex]
We can solve this problem using the distance formula, which gives us the distance between two points in a plane:
[tex]distance = \sqrt{((x2 - x1)^2 + (y2 - y1)^2)}[/tex]
Let (x, y) be a point with an x-coordinate of 2. Then we can write the distance from (-2, -4) to (x, y) as:
[tex]distance = \sqrt{((x - (-2))^2 + (y - (-4))^2)}[/tex]
Simplifying this expression, we get:
[tex]distance = \sqrt{((x + 2)^2 + (y + 4)^2)}[/tex]
We know that the distance between (-2, -4) and (x, y) is 5. Therefore, we can write:
[tex]\sqrt{((x + 2)^2 + (y + 4)^2)} = 5[/tex]
Squaring both sides, we get:
[tex](x + 2)^2 + (y + 4)^2 = 25[/tex]
Expanding the left side, we get:
[tex]x^2 + 4x + 4 + y^2 + 8y + 16 = 25[/tex]
Simplifying this expression, we get:
[tex]x^2 + 4x + y^2 + 8y - 5 = 0[/tex]
To find all points with an x-coordinate of 2 that satisfy this equation, we can substitute x = 2 and simplify the resulting equation:
[tex]2^2 + 4(2) + y^2 + 8y - 5 = 0[/tex]
Simplifying this equation, we get:
[tex]y^2 + 8y + 3 = 0[/tex]
We can solve this quadratic equation using the quadratic formula:
y = (-b ± sqrt(b^2 - 4ac)) / 2a
where a = 1, b = 8, and c = 3.
Plugging in these values, we get:
y = (-8 ± sqrt(8^2 - 4(1)(3))) / 2(1)
Simplifying this expression, we get:
y = (-8 ± √52) / 2
y = (-8 ± 2√13) / 2
y = -4 ± √13
Therefore, the two points with an x-coordinate of 2 and a distance of 5 from (-2, -4) are: (2, -4 + 2√13) and (2, -4 - 2√13)

Ms. Monroe ordered 24 costumes from Tip-Tap dance supply for each of her dance students to wear at an upcoming recital. Since she ordered during the store's end-of-season sale, Tip-Tap took $3.50 off the price of each costume. Ms. Monroe paid $516 in all.
Answer:
the original price of each costume was $25, and the sale price was $(25-3.50) = $21.50.
Step-by-step explanation:
Let the original price of each costume be $x. The sale price of each costume will be $(x-3.50). Ms. Monroe ordered 24 costumes, so the cost of 24 costumes at the sale price will be:
24 × (x-3.50) = $24x - $84
Ms. Monroe paid $516 in all, so we can write:
24x - 84 = 516
Adding 84 to both sides, we get:
24x = 600
Dividing both sides by 24, we get:
x = 25
Therefore, the original price of each costume was $25, and the sale price was $(25-3.50) = $21.50.
Answer: so Ms.Monroe got $84 off her entire purchase

The amount of depreciation to be recorded for year 2 using the straight-line method of calculating depreciation is $6,750.
What is the amount of depreciation to be recorded for year 2?Straight-line depreciation is calculated by dividing a fixed asset's depreciable base by its useful life. The depreciable base is the difference between an asset's all-in costs and the estimated salvage value at the end of its useful life.
By using the straight-line method of calculating depreciation, the annual depreciation expense would be calculated as follows:
= (Purchase Price - Salvage Value) / Useful Life
= ($60,000 - $6,000) / 8 years
= $54,000 / 8 years

Chris throws a ball upward. The height of the ball, in meters, t seconds after being
thrown is modeled by h (t)= 8t-5t² +4. After how many seconds will the ball reach
the ground?
Answer:
When the ball hits the ground, its height will be 0 meters. Therefore, we need to solve the equation:
h(t) = 0
8t - 5t^2 + 4 = 0
We can solve this quadratic equation by factoring or by using the quadratic formula, but in this case, it's easier to use factoring:
(5t - 4)(t - 1) = 0
From this equation, we can see that either 5t - 4 = 0 or t - 1 = 0. Solving for t in each case, we get:
5t - 4 = 0 ==> t = 0.8 seconds
t - 1 = 0 ==> t = 1 second
Therefore, the ball will reach the ground after either 0.8 seconds or 1 second, depending on the initial height of the ball.
you find sneakers for $79.95. In the paper you see they will be on sale for 63.96 next week what is the percent discount that they will be offering?
The percent discount being offered is 20%.
What is percentage ?
Percentage is a way of expressing a number as a fraction of 100. It is often denoted by the symbol %, which means "per cent" or "out of 100". Percentages are used to compare two quantities and express the relationship between them in terms of the fraction of one quantity that the other quantity represents.
To find the percent discount, we need to first calculate the amount of discount that is being offered. We can do this by subtracting the sale price from the original price:
Discount = Original Price - Sale Price
Discount = $79.95 - $63.96
Discount = $15.99
Next, we can calculate the percentage discount by dividing the discount by the original price and then multiplying by 100:
Percent Discount = (Discount / Original Price) x 100
Percent Discount = ($15.99 / $79.95) x 100
Percent Discount = 20%
Therefore, the percent discount being offered is 20%.

Each of the three oldest children sleeps in a twin bed. They all need bed sheets. A brand of sheets is on sale for “Buy one get one at 50% off”. If each sheet costs $18.00, how much will two sheets cost? How much will six sheets cost?
Using arithmetic operations, The total cost of six sheets will be:
$27.00 + ($9.00 x 4) = $63.00
If each sheet costs $18.00, then the cost of the first sheet will be $18.00, and the cost of the second sheet will be 50% of $18.00, or $9.00.
So, two sheets will cost the cost of the first sheet plus the cost of the second sheet, which is:
Using addition,
$18.00 + $9.00 = $27.00
For six sheets, we can use the same logic: the first two sheets will cost $27.00, and the next four sheets will be half off. So, the cost of the next four sheets will be 50% of $18.00, or $9.00 each.
Hence, the total cost of six sheets will be:

A mean ogre stole 20
of your muffins 5/8 of all of them how many are left?
Answer:
Let's start by finding out how many muffins were there in total before the ogre stole 20 of them. Let's call that number "x".
If 5/8 of them were left after the ogre stole 20, then 3/8 of them were taken.
So we can set up an equation:
x - 20 = 3/8x
To solve for x, we can start by multiplying both sides by 8 to get rid of the fraction:
8(x - 20) = 3x
8x - 160 = 3x
Now we can solve for x by subtracting 3x from both sides:
5x - 160 = 0
5x = 160
x = 32
So there were originally 32 muffins.
Now we can find out how many are left:
5/8 of 32 = 20
So there are 20 muffins left.
