In a large university, 70% of the students live in the dormitories. A random sample of 110 students is selected for a particular study.The probability that the sample proportion of students living in the dormitories falls in between 0.6 and 0.8 equals a.0.9780 b.0.9318 c.0.9365 d.1.6450
Answer:
The correct option is (a) 0.9780.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
\(\mu_{\hat p}=p\)
The standard deviation of this sampling distribution of sample proportion is:
\(\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}\)
As the sample selected is quite large, i.e. n = 110 > 30, the central limit theorem can be applied to approximate the sampling distribution of sample proportion by a Normal distribution.
The mean and standard deviation are:
\(\mu_{\hat p}=p=0.70\\\\\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.70(1-0.70)}{110}}=0.044\)
Compute the probability that the sample proportion of students living in the dormitories falls in between 0.60 and 0.80 as follows:
\(P(0.60<\hat p<0.80)=P(\frac{0.60-0.70}{0.044}<\frac{\hat p-\mu_{\hat p}}{\sigma_{\hat p}}<\frac{0.80-0.70}{0.044})\)
\(=P(-2.27<Z<2.27)\\\\=P(Z<2.27)-P(Z<-2.27)\\\\=0.98840-0.01160\\\\=0.9768\\\\\approx0.9780\)
*Use a z-table.
Thus, the probability that the sample proportion of students living in the dormitories falls in between 0.60 and 0.80 is approximately equal to 0.9780.
The correct option is (a).
8. What is the slope of the line?
A. 0
B. 1
C. Infinity
D. Undefined
Answer:
0.
Step-by-step explanation:
The slope of the line is defined as the change of elevation of the line (\(\frac{rise}{run}\)).
In this case, there is no change in the slope as the line continues across (0 , 2), meaning that the slope of the line is 0.
If the slope of the line is 1, then the line will have (rise 1/run 1), meaning that it will have a linear slope. (See attached image).
Vertical lines have infinite slope, and so can also be called undefined as it moves neither left or right, giving it no run.

sample is less than 0.7.
The probability that the third largest observation in the sample is less than 0.7 is 0.2401 = 24.01%.
How do we calculate?The sample size n = 5,
Therefore the order statistics will be represented as X₁, X₂, X₃, X₄, and X₅.
Probability that X₃ is less than 0.7:
Since X₃ is the third largest observation = (X₁ and X₂) < 0.7.
The probability that X₃ is less than 0.7 is (0.7)² = 0.49.
The Probability that X₁ and X₂ < or equal to 0.7 is found as:.
The probability that both X₁ and X₂ are less than or equal to 0.7 is (0.7)² = 0.49 because in a continuous uniform distribution, the probability of any single observation being less than 0.7 is 0.7 - 0 = 0.7.
We then get the product of both cases:

The difference between the actual quotient and the estimated quotient of 54,114 ÷ 29 is approximately 66.3448275862068965517241379.
To find the difference between the actual quotient and the estimated quotient of 54,114 ÷ 29, we need to first calculate the actual quotient and then the estimated quotient.
Actual quotient:
Dividing 54,114 by 29, we get:
54,114 ÷ 29 = 1,866.3448275862068965517241379 (approximated to 28 decimal places)
Estimated quotient:
Rounding the dividend, 54,114, to the nearest thousand gives us 54,000. Rounding the divisor, 29, to the nearest ten gives us 30. Now, we can perform the division with the rounded values:
54,000 ÷ 30 = 1,800
Difference between actual and estimated quotient:
Actual quotient - Estimated quotient = 1,866.3448275862068965517241379 - 1,800 = 66.3448275862068965517241379

Answer:
y = x² is the parent
y = 3/2(x+7)²+2 shifts 7 u left, up 2 u, and has vertical compression
Answer:
Right 7 unitsUp 2 unitsVertical StretchStep-by-step explanation:
Given the function, f(x) = 3/2(x + 7)² + 2,
where:
a = 3/2
vertex (h, k ) = (7, 2)
The value of a determines whether the graph opens up or down. The value of a also makes the parent function wider or narrower (vertical stretch by a factor of a ). If a > 1, the graph is narrower than the parent function. The value of h determines how far left or right the parent function is translated. If h is positive, the function is translated h units to the right. The value of k determines how far up or down the parent function is translated. If k is positive, the function is translated k units up.
Given these descriptions, we can assume that:
The function is vertically translated by 2 units upward. The function is horizontally translated by 7 units to the right.Vertical stretch by a factor of 3/2 (or 1.5).Please mark my answers as the Brainliest, if you find my explanations helpful :)

Are all intersecting lines perpendicular? Draw a picture to help explain your answer
Not all intersecting lines are perpendicular.
What are perpendicular lines?Perpendicular lines require a 90-degree angle of intersection, creating the formation of right angles.
Nonetheless, unlike perpendicular lines that necessitate exactly 90 degrees of intersections, other types of driven lines can be at varying angles beside these.
As such, it is critical to highlight that in general intersecting lines come with different angles of intersection, and only those featuring exact 90-degree angle of intersection become normal cases of intersecting lines, becoming one among many subtypes existing today.

(d) Find the rate of growth after 7 hours. (Round your answer to the nearest integer.) P(7) 2x bacteria/hour
(e) When will the population reach 200,000? (Round your answer to one decimal place.) hours
Answer:
a) P(0) = 80
b) \(P(t) = 80(2.2361)^t\)
c) 22,363 cells.
d) The rate of growth after 7 hours is of 18,000 bacteria per hour.
e) 9.7 hours.
Step-by-step explanation:
A bacteria culture grows with a constant relative growth rate.
This means that the population is given by:
\(P(t) = P(0)(1+r)^t\)
In which P(0) is the initial population and r is the growth rate, as a decimal.
After 2 hours there are 400 bacteria and after 8 hours the count is 50,000.
This means that in 6 hours, the population went from 400 bacteria to 50,000 bacteria. We use this to find r. So
\(50000 = 400(1+r)^6\)
\((1+r)^6 = \frac{50000}{400}\)
\((1+r)^6 = 125\)
\(\sqrt[6]{(1+r)^6} = \sqrt[6]{125}\)
\(1 + r = 125^{\frac{1}{6}}\)
\(1 + r = 2.2361\)
So
\(P(t) = P(0)(2.2361)^t\)
(a) Find the initial population. P(0)
We have that P(2) = 400. We use this to find P(0). So
\(P(t) = P(0)(2.2361)^t\)
\(400 = P(0)(2.2361)^2\)
\(P(0) = \frac{400}{(2.2361)^2}\)
\(P(0) = 80\)
So
\(P(t) = 80(2.2361)^t\)
(b) Find an expression for the population after t hours.
\(P(t) = 80(2.2361)^t\)
(c) Find the number of cells after 7 hours.
This is P(7). So
\(P(7) = 80(2.2361)^7 = 22363\)
22,363 cells.
(d) Find the rate of growth after 7 hours.
We have to find the derivative when t = 7. So
\(P(t) = 80(2.2361)^t\)
\(P^{\prime}(t) = 80\ln{2.2361}(2.2361)^t\)
\(P^{\prime}(7) = 80\ln{2.2361}(2.2361)^7 = 18000\)
The rate of growth after 7 hours is of 18,000 bacteria per hour.
(e) When will the population reach 200,000?
This is t for which \(P(t) = 200000\). So
\(P(t) = 80(2.2361)^t\)
\(200000 = 80(2.2361)^t\)
\((2.2361)^t = \frac{200000}{80}\)
\((2.2361)^t = 2500\)
\(\log{(2.2361)^t} = \log{2500}\)
\(t\log{2.2361} = \log{2500}\)
\(t = \frac{\log{2500}}{\log{2.2361}}\)
\(t = 9.7\)
So 9.7 hours.
A car travels a distance of 112km at an average Speed of 70km/h. It then Travells Further for 60km at an average Speed of 50 km/hr. Calculate for the entire Journey of the total time taken.
The total time taken for the entire journey is 2.8 hours.
To calculate the total time taken for the entire journey, we can use the formula:
Time = Distance / Speed
For the first part of the journey, the car travels a distance of 112 km at an average speed of 70 km/h. Using the formula, the time taken for this part is:
Time1 = 112 km / 70 km/h = 1.6 hours
For the second part of the journey, the car travels a further distance of 60 km at an average speed of 50 km/h. Again, using the formula, the time taken for this part is:
Time2 = 60 km / 50 km/h = 1.2 hours
To find the total time for the entire journey, we sum up the times for both parts:
Total Time = Time1 + Time2 = 1.6 hours + 1.2 hours = 2.8 hours

Covariance : 0.459 = COV(s,b)/0.43×0.37
Covariance = 0.073
Stock Fund =( (σB)²− σS× σB× correationco, SandB)/((σS)²(σB)² - 2 × σS× σB× correationco, SandB)
