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.

determine whether the statement describes a descriptive or inferential statistic. a survey of 1455 people revealed that 53% work a full-time job; therefore it can be assumed that 53% of the u.s. population works a full-time job.
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.

decreased by 100 students every two years.
Choose the formula below which gives the function N(t) representing the number of students attending the charter school
t years after 2005.
Select the correct answer below:
ON(t) = 100t + 350
ON(t)=-100t + 350
ON(t) = 50t + 350
ON(t) = -50t + 350

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.

Solve for the value of p.
(6p+3) (9p-3)°
Answer:
p = 12
Step-by-step explanation:
Angles in a straight line sum to 180 degrees. Given the two algebraic angles, this can be expressed as follows:
(6p + 3) + (9p - 3) = 180
Take out the brackets:
6p + 3 + 9p - 3 = 180
Combine the like terms:
15p = 180
Divide both sides by 15:
p = 180/15
Simplify:
p = 12
If you want to verify the answer is correct, substitute it back into the original equation:
(6(12) + 3) + (9(12) - 3) = 180

The unknown angles are as follows:
x = 29z = 13∠RIG = 59°∠ZIM = 149°How to find angles when line intersect?∠AIM is perpendicular to IR.
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
∠ZIM = 52 + 7 + 90
∠ZIM = 59 + 90
∠ZIM = 149 degrees

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.

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'.

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 area of the rectangle is 576.
An area is the total amount of space enclosed by a shape or figures. In this case, the rectangle would be the shape or figure that is being defined and its area would be the total amount of space enclosed by it.
The length of the rectangle is 13 less than 2 and a half times its width means : L=2 [tex]\frac{1}{2}[/tex] w-13
Using the perimeter formula of the rectangle P= 2(L-W) we have
P=100
So
100=2(2( [tex]\frac{1}{2}[/tex])w-13+w)
Solve for W:
100= 2×[tex]\frac{5}{2}[/tex]w-26+2w
100=10/2w-26+2w
100=5w-26+2w
100=7w-26
100+26=7w
126=7w
126/7=w
W=18
We can find the length L=2 [tex]\frac{1}{2}[/tex]w-13 = [tex]\frac{5}{2}[/tex](18) -13
