A leak in a pool causes the height of the water to decrease by 0.25 foot over 2 hours. After the leak is fixed, the height of the water is 4.75 feet. The equation 4.75 = x + (negative 0.25) can be used to find x, the original height of the water in a pool.
What was the original height of the water in the pool in feet?
Answer:
Assuming the leak took 2 hours to fix, the original height of the pool is 5 feet.
Step-by-step explanation:
This is probably the most simple "high school" problem I've seen in a while. All you have to do is move the negative 0.25 to the other side to isolate x. That gives you 4.75 + 0.25, or 5 feet.
The original height of the water in the pool was 5 feet.
Given that there is leak in a pool causes the height of the water to decrease by 0.25 foot over 2 hours.
After the leak is fixed, the height of the water is 4.75 feet.
The equation 4.75 = x - 0.25 can be used to find x, the original height of the water in a pool.
we need to find the original height of water,
To find the original height of the water in the pool, we can use the given information and equation.
Let's break down the equation: 4.75 = x - 0.25
Here, x represents the original height of the water in the pool, and -0.25 represents the decrease caused by the leak.
The equation states that after the leak is fixed, the height of the water in the pool is 4.75 feet. This means that the final height (4.75 feet) is equal to the original height (x) minus the decrease caused by the leak (-0.25 feet).
To solve for x, we can isolate it on one side of the equation.
Adding 0.25 to both sides of the equation, we get:
4.75 + 0.25 = x - 0.25 + 0.25
Simplifying the equation, we have:
5 = x
Therefore, the original height of the water in the pool was 5 feet.

Refer to the data set of 20 randomly selected presidents given below. Treat the data as a sample and find the proportion of presidents who were taller than their opponents. Use that result to construct a 95% confidence interval estimate of the population percentage. Based on the result, does it appear that greater height is an advantage for presidential candidates? Why or why not?
Complete Question
The data for this question is shown on the first uploaded image
Answer:
The 95% confidence interval estimate of the population percentage is
[tex] 33.2\% < p < 76.8 \% [/tex]
Step-by-step explanation:
On the data the first value is the height of the president while the other value is the height of his opponent
The sample size is n = 20
Looking at the data we see that out of the 20 presidents that only 11 is taller than their opponent
So the proportion of presidents that are taller than their opponents is
[tex]\^ p = \frac{11}{20}[/tex]
=> [tex]\^ p = 0.55[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p) }{n}} [/tex]
[tex]E = 1.96 * \sqrt{\frac{0.55 (1- 0.55) }{20}} [/tex]
[tex]E = 0.218[/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\r p -E < p < \r p +E[/tex]
=> [tex]0.55-0.218 < p < 0.55+ 0.218 [/tex]
=> [tex]0.332 < p < 0.768 [/tex]
Converting to percentage
[tex](0.332*100)\% < p < (0.768 *100) \% [/tex]
=> [tex] 33.2\% < p < 76.8 \% [/tex]
The temperature at midnight was -6 degrees celsius. By 7 am, it had risen 6.5 degrees. By noon, it had risen another 3.9 degrees. Then a storm blew in, causing it to drop 4/25 degrees by 6 am. what was the temperature at 6pm?
Answer: 4.15 degrees
Step-by-step explanation:
-6 + 6.5 + 3.9 - 4/25 = -6 + 6.5 + 3.9 - 0.25 = 4.15 degrees (assuming that the am in the fourth sentence is a typo)

The phrase that best represents six times the quantity of four plus a number is 6(4) + n.
What is a numerical expression ?A numerical expression is a form where we express a statement by number and their operations.
According to the given phrase six times the quantity four which is 6(4) plus a number.
6(4) + n.
What we have done here is we formed a numerical expression from a given statement.
Suppose we have given sum of 4 and thrice of a number is 10.
So, 4 + 3n = 10
3n = 10 - 4
3n = 6
n = 2.
So the number is 2.

Over which interval of the domain is the function increasing?
i didnt mean to click B btw
Answer:
B
Step-by-step explanation:
It appears to be B because this quadratic function faces down (-ax^2) and the vertex or highest point of this function is when x=1. Thus, the interval of the domain that the function increases must be from negative infinity to 1, giving the answer B.

Hope that helps and have a great day!
Answer:
[tex]y=\frac{1}{2}x+2[/tex]
Step-by-step explanation:
To find the equation for the line, lets try to find the slope and y-intercept of the line.
From looking at the graph, we can see that the line intersects the y-axis at y = 2. So the y-intercept would be 2.
The slope of the line would be the rise divided by the run. Looking at the graph, we can see that for every 2 the line moves in the x-direction, it moves 1 in the y-direction. This means that the rise is 1 and the run is 2. So the slope would be 1/2.
So we now know that the slope is 1/2 and the y-intercept is 2, we can now plug the information into the slope-intercept form.
Slope-intercept form is:
y = mx + b
where m is the slope and b is the y-intercept.
Plugging in we get
[tex]y=\frac{1}{2}x+2[/tex]
And now we have the equation of the line.

Answer:
$9.95
Step-by-step explanation:
$238.80 ÷ 24 = $9.95
$238.80 ⇾ The final cost of boxed lunches altogether.
24 ⇾ The number of boxed lunches bought.
$9.95 ⇾ The unit price of boxed lunches after dividing the final cost($238.80) by the amount bought(24).

What is the equation of a line that passes through the point (-7,-8) and parallel to y=5/7x-5.
Answer:
The equation of the line that passes through the point (-7, -8) and parallel to the given line is y = 5/7·x - 3
Step-by-step explanation:
The coordinates of the point the line passes = (-7, -8)
The equation of the line the required line is parallel to is y = 5/7·x - 5
The slope of of the given line is therefore in slope and intercept form with the slope = 5/7 and the y-intercept = -5
The slope of a line parallel to another line are equal, therefore the slope of the required line = The slope of the given line = 5/7
The equation of the required line in point slope form is therefore;
y - (-8) = 5/7 × (x - (-7))
y + 8 = 5/7 × x + 5/7 × 7
y + 8 = 5/7 × x + 5
∴ y = 5/7 × x + 5 - 8 = 5/7 × x - 3
y = 5/7 × x - 3
The equation of the line that passes through the point (-7, -8) and parallel to y = 5/7x - 5 is y = 5/7·x - 3.

Translation !! keep getting random people Please only answer if u really know ! Thanks
Answer:
The direction matters , but only in sign... so from A to A' is what i'm guessing is the direction of translation
Step-by-step explanation:
find the vector from A to A' or any of the other non prime to prime points.. the vector will be the same... soooo
take the origin point as P1 , then take the destination point a P2
and subtract P2-P1
P2 = A' = (6,-2)
P1 = A = (2, 1)
(6-2, -2-1) = (4,-3)
your vector can be place at the origin.. and go 4 in the x direction and -3 in the y direction and you get that translation.. make sense?
