Answer:
Discrete
Step-by-step explanation:
Given
Number of phone calls between two cities on Thanks giving day
Required
Discrete or Continuous
Number of phone calls can be represented as thus:
0, 1, 2 , 3 , 10, 20, 100 or any other positive whole numbers
Only discrete data take form of the above.
Hence, "Discrete" answers the question
The given random variable is discrete and this can be determined by observing the given data.
Given :
The number of phone calls between New York and California on Thanksgiving day.
The following steps can be used in order to determine the given random variable as being discrete or continuous:
Step 1 - According to the given data, the number of phone calls between New York and California on Thanksgiving day.
Step 2 - So, the total number of calls on thanksgiving day may be 0, 2, 6, 9, 15, 100, 115, or whole positive number.
Step 3 - So, from the above steps, it can be concluded that the given random variable is discrete.

When you take samples from a population and compute a proportion from each one, you can consider the distribution of those proportions. This is called the sampling distribution for the population proportion.The Central Limit Theorem tells us that the sampling distribution for the population proportion is
Answer:
Step-by-step explanation:
This is a fill in the gap question:
The Central Limit Theorem tells us that the sampling distribution for the population proportion is approximately normal with the population proportion as its mean. The theorem of the central limit is a set of results on the weak convergence of a series of random variables in probability. Intuitively, according to these results, any sum of independent and identically distributed random variables tends towards a certain random variable.
Similarly; from the question:
The mean of the sampling distribution is given by [tex]\mathbf{\mu_{\hat p } = p}[/tex]
Suppose p is the population proportion and let say n is the sample size; then :
The standard deviation of the sampling distribution can be represented by :
[tex]\sigma_{\hat p} = \sqrt{\dfrac{p(1-p)}{n}}[/tex]

What conditions are required by the central limit theorem before a confidence interval of the population mean may be created
Answer:
In the clarification segment elsewhere here, the definition including its query is mentioned.
Step-by-step explanation:
Unless the sample group exceeds 30 or even more, their underlying demographic doesn't have to be positively correlated since the Central limit theorem claims that even if sample sizes with n observations being obtained from every other population. Then, whenever n is high, [tex]n \geq 30[/tex], the sampling distribution of the distribution of values has been determined roughly normally.How to round the decimal 5.37

Katie ran four miles she ran at a rate that was 1.1 miles per mile slower than Jasmine Jasmine ran at a rate of 8.4 minutes per mile for how many minutes did Katie run? Explain how you determined your answer.
Answer:
Katie spent 29.2 minutes
Step-by-step explanation:
I hope this helps!!!
Answer:
29.2 minutes
Step-by-step explanation:
If Jasmine ran 5 miles in 42 minutes. Katie ran 4 miles. She ran at a rate that was 1.1 minutes per mile slower than Jasmine. For how many minutes did Katie run? Explain how you determined your answer. So basically When you run slower you subtract so 8.4 minus 1.1 is 7.3. And then multiply it by 4 and get 29.2 You can check your answer by dividing 29.2 by 7.3

Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.

An article presents a study of the effect of the subbase thickness on the amount of surface deflection caused by aircraft landing on an airport runway. In six applications of a 160 kN load on a runway with a subbase thickness of 864 mm, the average surface deflection was 2.34 mm with a standard deviation of 0.090 mm. Find a 90% confidence interval for the mean deflection caused by a 160 kN load. Round the answers to three decimal places. The 90% confidence interval is ( , ).
Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean.
Given that: sample size (n) = 6, standard deviation (σ) = 0.09 mm, mean (μ) = 2.34 mm
The confidence interval = 90% = 0.9
α = 1 - 0.9 = 0.1
α / 2 = 0.05
The z score of 0.05 is the same as the z score of 0.45 (0.5 - 0.05) which is 1.645.
The margin of error is given as:
[tex]E=Z_{\frac{\alpha}{s} }*\frac{\sigma}{\sqrt{n} }[/tex]
[tex]E=1.645*\frac{0.09}{\sqrt{6} }=0.06\ mm[/tex]
The confidence interval = μ ± E = 2.34 ± 0.06 = (2.28, 2.40)
The confidence interval is between 2.28 mm and 2.4 mm
You have 2 cups of raisins. A recipe calls for 3/8 cup of raisins per serving. How many FULL Servings can you make?
Answer:
5
Step-by-step explanation:
There are 2 cups of raisins
A recipe requires 3/8 cup of raisins per serving
Therefore the number of full servings that can be made can be calculated as follows
= 2 ÷3/8
= 2 × 8/3
= 16/3
= 5.3333
Hence the number of full servings that can be made is 5

What did you learn about using the Pythagorean Theorem from this lesson?
Step-by-step explanation:
Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.
Answer:
Pythagorean Theorem: a squared + b squared = c squared
Pythagorean Theorem: implies in every single triangle

When a number is subtracted from half of its own square the result is 60. What is the number?
Answer:
-10 or 12
Step-by-step explanation:
1/2 y2 -y =60
Multiply both sides by 2
y2 - 2y =120
Subtract 120 from both sides
y2 - 2y -120 = 0
Factor the left side ( y+10) (y -12 =0)
By zero product property, y= -10,12
So the number is -10 or 12
