The value of 25 cm/s = 900 m/h using the dimensional analysis.
How is dimensional analysis employed and what does it entail?Examining the dimensions of the relevant physical variables is a key step in the study and solution of issues in science and engineering using dimensional analysis. Physical quantities have defined dimensions and are stated in terms of units like metres, kilogrammes, seconds, and degrees Celsius. Physical quantities also include length, mass, time, and temperature. Dimensional consistency in physical equations and connections is the fundamental tenet of dimensional analysis.
To convert 25 cm/s to m/h using dimensional analysis, we have:
1 m = 100 cm
1 h = 3600 s
25 cm/s x (1 m/100 cm) x (3600 s/1 h) = 900 m/h
Hence, the value of 25 cm/s = 900 m/h using the dimensional analysis.

Many families in California are using backyard structures for home offices, art studios, and hobby areas as well as for additional storage. Suppose that the mean price for a customized wooden, shingled backyard structure is $3100. Assume that the standard deviation is $1200.
a. What is the z-score for a backyard structure costing $2300?
b. What is the z-score for a backyard structure costing $4900?
c. Interpret the z-scores in parts (a) and (b). Comment on whether either should be considered an outlier.
d. If the cost for a backyard shed-office combination built in Albany, California, is $13,000, should this structure be considered an outlier? Explain.
The z-score is a measure of how many standard deviations a data point is from the mean. It can be calculated using the formula
z = (x - μ) / σ,
where x is the data point, μ is the mean, and σ is the standard deviation.
a. The z-score for a backyard structure costing $2300 can be calculated as follows:
z = (2300 - 3100) / 1200 = -800 / 1200 = -0.67
b. The z-score for a backyard structure costing $4900 can be calculated as follows:
z = (4900 - 3100) / 1200 = 1800 / 1200 = 1.
c. The z-score in part (a) is -0.67, which means that the backyard structure costing $2300 is 0.67 standard deviations below the mean. The z-score in part (b) is 1.5, which means that the backyard structure costing $4900 is 1.5 standard deviations above the mean. Neither of these z-scores are extreme enough to be considered outliers, as they are both within 2 standard deviations of the mean.
d. The z-score for the backyard shed-office combination costing $13,000 can be calculated as follows:
z = (13000 - 3100) / 1200 = 9900 / 1200 = 8.25
This z-score is much larger than 2, which means that the structure costing $13,000 is more than 8 standard deviations above the mean. This is an extreme value and should be considered an outlier.

Suppose that X is an event, and that P(X)=0.66 . What is P( X ˉ ) (i.e. the probability that X will not occur)? Answer = You have attempted this problem 0 times. You have unlimited attempts remaining.
The probability of X not occurring is 0.34.
What is Probability?
Probability is a branch of mathematics concerned with measuring the likelihood of events. It involves studying random phenomena, such as coin tosses, rolling dice, or weather patterns, and assigning numerical values to the likelihood of different outcomes .The formal definition of probability is based on the concept of equally likely outcomes, where the probability of an event is the ratio of the number of favorable outcomes to the total number of outcomes
If P(X) = 0.66, then the probability of not X occurring (i.e., X complement or X bar) is:
P(X bar) = 1 - P(X)
P(X bar) = 1 - 0.66
P(X bar) = 0.34
Therefore, the probability of X not occurring is 0.34.

An increasing number of consumers believe they have to look out for themselves in the marketplace. According to a survey conducted by the Yankelovich Partners for USA WEEKEND magazine, 60% of all consumers have called an 800 or 900 telephone number for information about some product. Suppose a random sample of 25 consumers is contacted and interviewed about their buying habits
The probability that 11 or more of these consumers have called an 800 or 900 telephone number for information about some product is approximately 0.326.
How is the binomial probability distribution employed in statistics? What is it?The number of successes in a certain number of independent trials that all have the same probability of success are described by the discrete probability distribution known as the binomial probability distribution. The probability of success is constant during all trials, and it is used in statistics to describe situations where there are two alternative outcomes (success or failure).
The binomial probability distribution is given as:
P(X ≥ k) = 1 - P(X < k)
Here, p = 0.60, and the sample size is n = 20.
Thus,
P(X ≥ 11) = 1 - P(X < 11)
= 1 - ∑(20 choose x) (0.6)ˣ (0.4)⁽²⁰⁻ˣ⁾ for x from 0 to 10
P(X ≥ 11) = 0.326

At a football game, a vender sold a combined total of 137 sodas and hot dogs. The number of sodas sold was 49 more than the number of hot dogs sold. Find the number of sodas sold and the number of hot dogs sold. Number of sodas sold: Number of hot dogs sold:
Answer:
From the problem, we know that:
s + h = 137 (the total number of sodas and hot dogs sold is 137)
s = h + 49 (the number of sodas sold is 49 more than the number of hot dogs sold)
Now we can substitute the second equation into the first equation:
(h + 49) + h = 137
Simplifying this equation:
2h + 49 = 137
Subtracting 49 from both sides:
2h = 88
Dividing both sides by 2:
h = 44
Now we know that 44 hot dogs were sold. We can use the second equation to find the number of sodas sold:
s = h + 49
s = 44 + 49
s = 93
Therefore, 93 sodas were sold.
Number of sodas sold: 93
Number of hot dogs sold: 44
Step-by-step explanation:
Answer: Let's use variables to represent the number of sodas and hot dogs sold.
Let x be the number of hot dogs sold.
According to the problem, the number of sodas sold was 49 more than the number of hot dogs sold, so the number of sodas sold is x + 49.
The problem also tells us that the combined total of sodas and hot dogs sold was 137. So we can set up an equation:
x + (x + 49) = 137
Simplifying the left side:
2x + 49 = 137
Subtracting 49 from both sides:
2x = 88
Dividing both sides by 2:
x = 44
So the number of hot dogs sold was 44.
To find the number of sodas sold, we can use the expression we set up earlier:
x + 49
Substituting in our value for x:
44 + 49 = 93
So the number of sodas sold was 93.
Answer: Number of sodas sold: 93, Number of hot dogs sold: 44.

If we assume that Claudio passed out p tamales, then the number of tamales remaining would be:
300 - p
If Claudio passed out samples to 160 pedestrians, then the number of tamales remaining would be:
300 - 160 = 140
Therefore, 140 tamales would remain.

A 15-foot ladder is leaning against a wall of a building. If the top of the ladder makes a 72° angle with the wall of the building, approximately how high above the ground is the top of the ladder?
Answer:
14.2665 feet above the ground
Step-by-step explanation:
We can use trigonometry to solve this problem. Let's call the height of the ladder on the wall "h". Then we have:
sin(72°) = h/15
Multiplying both sides by 15, we get:
h = 15 sin(72°)
Using a calculator, we find that sin(72°) is approximately 0.9511. So:
h ≈ 15 × 0.9511
h ≈ 14.2665
Therefore, the top of the ladder is approximately 14.2665 feet above the ground.
Solve the equation.
5(y+2/5)=−13
y = ?
Answer:
-3
Step-by-step explanation:
5(y+2/5)=-13
5*y+5*2/5=-3
5y+2=-13
5y=-13-2
5y=-15
5y/5=-15/5
y=-3
Answer:
y = -3
Step-by-step explanation:
Now we have to,
→ Find the required value of y.
The equation is,
→ 5(y + (2/5)) = -13
Then the value of y will be,
→ 5(y + (2/5)) = -13
→ 5(y) + 5(2/5) = -13
→ 5y + (10/5) = -13
→ 5y + 2 = -13
→ 5y = -13 - 2
→ 5y = -15
→ y = (-15)/5
→ [ y = -3 ]
Hence, the value of y is -3.
