joyce paid $80 for an item at the store that was 30 percent of the original price. what was the original price?
$114 was the original price of an item.
What does the word percent mean?
A percentage is a ratio or fraction where the full value is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test. In ratio form, it is expressed as 30:100 and in fraction form as 30/100.Equation for Price Reduction:
Original Price * Percent Remaining of Original = New Price
Plug in the given values into the equation:
Original Price * 0.7 = $80
Divide both sides by 0.7 to isolate the Original Price:
80/0.7 = $114

according to a report on sleep deprivation by the centers for disease control and prevention, the proportion of california residents who reported insufficient rest or sleep during each of the preceding 30 days is 8.0%, while this proportion is 8.8% for oregon residents. these data are based on simple random samples of 11,545 california and 4,691 oregon residents. perform a hypothesis test to investigate if there is evidence of a difference in proportion at a significance level of 0.05. conclude in the context of the study. list the conditions for this hypothesis test.
The 95% confidence range for the difference in the percentages of sleep deprived people in California and Oregon is from -0.0015 to 0.0175.
With a 95% confidence level or 0.05 significance level, we may say that this range overlaps 0 and that the proportions are not statistically different. In other words, based on the findings from this sample, the proportion of the CA and OR populations may be equal.
What is a confidence interval?
A confidence interval (CI) is a range of estimates for an unknown parameter in frequentist statistics. The 95% confidence level is the most popular, however other levels, such 90% or 99%, are occasionally used when computing confidence intervals. The percentage of related CIs over the long run that include the parameter's actual value is represented by the confidence level. For instance, 95% of all intervals calculated at the 95% level should include the parameter's actual value.

Find the coordinates of the midpoint of a segment with the given endpoints. Then find the distance between the following pair of points. (Lesson 1-3)
P(26,12) and Q(8,42)
The coordinates of the midpoint is M(x, y) = (17, 27) and its length is 6√34 units.
How to find the coordinates of the midpoint of a line segment
In this problem we have the coordinates of two endpoints of a line segment, of which we must find the location of its midpoint by using the midpoint formula, whose vector form shall be used. Later, we determine the length of the line segment by calculating the vector behind the line segment and its magnitude.
If we know that P(x, y) = (26, 12) and Q(x, y) = (8, 42), then the location of its midpoint and its length are, respectively:
Midpoint
M(x, y) = 0.5 · P(x, y) + 0.5 · Q(x, y)
M(x, y) = 0.5 · (26, 12) + 0.5 · (8, 42)
M(x, y) = (13, 6) + (4, 21)
M(x, y) = (17, 27)
Length
PQ = (8, 42) - (26, 12)
PQ = (- 18, 30)
PQ = √[(- 18)² + 30²]
PQ = 6√34
The coordinates of the midpoint is M(x, y) = (17, 27) and its length is 6√34 units.

The given statement describes descriptive statistics.
What is Descriptive statistics?In the count noun sense, a descriptive statistic is a summary statistic that quantitatively describes or summarizes features from a collection of data, whereas descriptive statistics (in the mass noun sense) is the process of using and analyzing those statistics. Descriptive statistics differ from inferential statistics (or inductive statistics) in that they seek to summarize a sample rather than learn about the population that the sample of data is thought to represent. This generally means that, unlike inferential statistics, descriptive statistics are not based on probability theory and are frequently nonparametric statistics. For example, knowing that all of the participants in our example wore blue shoes would be useless.Therefore, the given statement describes descriptive statistics.

A team of explorers on a expedition was interupted by bad weather on 20%, if the weather was bad for 45 days what was the total number of days were on the missoin
The mission was of 225 days.
We are informed from the question the percentage of bad days and number of bad days. So, relating the two parts of question will give the number of days explorers were on mission. Let us assume the total number of days of mission be x.
20% × x = 45
Solving the equation now -
20/100x = 45
Shifting 100 to Right Hand Side of the equation as denominator
20x = 45 × 100
Performing multiplication on Right Hand Side of the equation
20x = 4500
Shifting 20 to denominator on Right Hand Side of the equation
x = 4500 ÷ 20
Performing division on Right Hand Side of the equation
x = 225
Hence, explorers were on mission for 225 days.

Mona is purchasing a shirt. the total cost, c, of the shirt will be the price of the shirt, p, increased by 6% of the price of the shirt for sales tax. write an equation that represents the total cost of the shirt?
The equation representing total cost of the shirt is c = 1.06p.
As per the question, we are representing the total cost of the shirt as c and price of the shirt as p.
Calculating sales tax on the shirt -
Sales tax = p × 6%
Converting percentage to fraction and hence decimal form
Sales tax = p× 6/100
Sales tax = 0.06p
Forming the equation now -
Total cost = price of the shirt + sales tax on the shirt
c = p + 0.06p
Performing addition on Right Hand Side of the equation to find the equation representing total cost
c = 1.06p
Therefore, the equation representing the total cost of the shirt is c = 1.06p.

Therefore,
∠RIM = 90°
Line AM, ZG and RI intersect at point I.
Therefore,
3x - 56 = x + 2 (vertically opposite angles)
3x - x = 2 + 56
2x = 58
x = 58 / 2
x = 29
4z + 7 + x + 2 = 90
4z + 7 + 29 + 2 = 90
4z = 90 - 7 - 2 - 29
4z = 52
z = 52 / 4
z = 13
∠RIG = 4z + 7
∠RIG = 4(13) + 7
∠RIG = 52 + 7
∠RIG = 59°
∠ZIM = 4z + 7 + 90
∠ZIM = 4(13) + 7 + 90

We'll observe that the evaluated expression equals 244 in the next step.
How is an expression evaluated?To evaluate an expression, we only need to swap out the variables with the desired values.
What does evaluating expressions look like in practice?When x = 5 x = 5 x=5, you can be asked to "Evaluate 3 x 3x 3x." In the formula 3 x 3x 3x, take note of the proximity of the number 3 to the variable x. This denotes "x times three."
Here, we must assess:
2(s+t)³-6
By substituting them in the formula for t = 2 and s = 3, we obtain:
2(3+2)³- 6
= 2*(5) (5)³ - 6

Suppose that 24 inches of wire costs 72. At the same rate, how much (in cents) will 49 inches of wire cost?
I'm assuming the "costs 72" is referring to 72 cents.
If so, then this is one way to solve:
(24 inches)/(72 cents) = (49 inches)/(x cents)
24/72 = 49/x
24*x = 72*49
x = 72*49/24
x = 147
It costs 147 cents, aka $1.47, to get 49 inches of wire.
what is the measure of the smaller angle between the hands of a $12$-hour clock at $12:25$ pm, in degrees?
The smaller angle made by the hour hands of a clock at a given time is 137°30'. It is attained by using the concept of clocks on the problems.
What is a clock?
A clock is a device which is used for measuring and indicating the time. It has three hands, namely an hour hand, a minute hand and a second hand. A clock can be classified in two ways, one is a 12-hour clock and the other is a 24-hour clock.
Calculation of the smaller angle made by the hour hand
For minute hand,
60 min makes an angle 360°
1 min = 6°
25 min = 6° × 25
= 150°
For hour hand,
12 hours makes an angle 360°
1 hour = 30°
1 min = 30° / 60
= 1/2°
25 min = 1/2° × 25
= 12°30'
The smaller angle made by hour hand is given by 150° - 12°30'
=137°30'
Hence, the smaller angle between the hour hands is 137°30'.
