What additional information is obtained by measuring on an interval scale compared to an ordinal scale?
Answer:
Step-by-step explanation:
From the given information.
An ordinal scale measurement does not give room to know the actual difference that coexists between the two measurements in a variable but in an interval scale of measurement, it is possible to deduce the actual difference that coexists between the two measurements in a variable.
Similarly, the ordinal scale only shows the rank of observations as per size and magnitude but in case of interval scale, it consists of classes with equal size, differentiated into direction and magnitude.
What is the slope of this line?
Enter your answer as a whole number or a fraction in simplest form in the box.
Answer:
1/4 is the clope of the line
Step-by-step explanation:
a slope is just a rise ofver run from one dot to anothor so you go up 1 and over 4 and if you dont do the 2 dots that are closest to each other you have to simplify you r exspresion you will always get 1/4 on this graph
The product of two consecutive numbers is 1295, find the numbers.
Answer:
36.49 and 35.49
Step-by-step explanation:
Let the two consecutive number be x-1 and x
If their product is 1295, then;
x(x-1) = 1295
x² - x = 1295
x²-x - 1295 = 0
x = 1±√(-1)²-4(-1295)/2
x = 1±√1+5180/2
x = 1±71.98/2
x = 72.98/2
x = 36.49
x - 1 = 35.49
Hence the two numbers are 36.49 and 35.49

I need help I'm in 5th grade
Answer:
C. 3 5/18
Step-by-step explanation:
What we know:
Joel purchased 5 7/9 lb of grapes, while Jim purchased 2 1/2 lb.
What we need to find out:
How many more pounds of grapes does Joel have than Jim.
What we need to do:
Subtract 2 1/2 from 5 7/9.
But first, we need a common denominator.
2 and 9 don't have any common factors so multiply normally.
2 * 9 = 18
5 7/9 becomes 5 14/18, and 2 1/2 becomes 2 9/18.
Now to subtract.
(5 - 2) + ((14-9)/18)
3 + ((14-9)/18
3 + 5/18
Joel has 3 5/18 more pounds of grapes than Jim, so the answer is C.
Answer:
C
Step-by-step explanation:
5 7/9 - 2 1/2 = 5 14/18 - 2 9/18 = 3 5/18

Answer:
y + 6 = 3/5(x - 4)
Step-by-step explanation:
Point-slope is the general form y-y₁=m(x-x₁)
y1 = -6, x1 = 4
y - (-6) -> y +6
y +6 = 3/5(x - 4)

The manager of a night club in Boston stated that 85% of the customers are between the ages of 21 and 27 years. If the age of customers is normally distributed with a mean of 24 years, calculate its standard deviation.
Answer:
The standard deviation of the age of the customers was of 2.08 years.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
[tex]\mu = 24[/tex]
85% of the customers are between the ages of 21 and 27 years.
Since the normal distribution is symmetric, this means, for example, that 27 is the 50 + (85/2) = 92.5th percentile, that is, when [tex]X = 27[/tex], Z has a pvalue of 0.925. So when [tex]X = 27, Z = 1.44[/tex]. We use this to find [tex]\sigma[/tex]
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.44 = \frac{27 - 24}{\sigma}[/tex]
[tex]1.44\sigma = 3[/tex]
[tex]\sigma = \frac{3}{1.44}[/tex]
[tex]\sigma = 2.08[/tex]
The standard deviation of the age of the customers was of 2.08 years.

Solve for s.
1/2 s =7/2
A s= 1/7
B s=2/7
C s= 3
D s =7
To solve this equation, first get rid of the fractions.
We do this by multiplying both sides by the denominator, 2.
So we have (2)(1/2s) = (7/2)(2).
On the left, we have s and on the right, we have 7.
So we have s = 7.
