The number of two-portal caves is three times the number of three-portal caves. How many caves are in the video game
Answers
Answer:
95 - 9x
Step-by-step explanation:
All caves have ; 2 or 3 portals
Total portals = 95 more than number of caves
Let :
Number of 3 portal caves = x
Number of 2 portal caves = 3x
Total Number of portals :
3x + 2(3x) = 3x + 6x = 9x
Number of caves :
95 - 9x

In a study of speed dating, female subjects were asked to rate the attractiveness of their male dates, and a sample of the results is listed below (1not attractive; 10extremely attractive). Find the range, variance, and standard deviation for the given sample data. Can the results be used to describe the variation among attractiveness ratings for the population of adult males
Answers
Answer:
[tex]Range = 7[/tex]
[tex]s^2 = 3.53[/tex] -- Variance
[tex]s = 1.88[/tex] --- Standard Deviation
No, it can not be used
Step-by-step explanation:
Given
I'll use the data in the attachment to answer the question.
(a) Range:
[tex]Range = Highest - Lowest[/tex]
From the attached data.
[tex]Highest = 10[/tex]
[tex]Lowest = 3[/tex]
So:
[tex]Range = 10 - 3[/tex]
[tex]Range = 7[/tex]
(b) Variance:
We start by calculating the mean:
[tex]\overline x = \frac{\sum x}{n}[/tex]
[tex]\overline x = \frac{5 + 8 + 3 + 8 + 6 + 10 + 3 +......+ 8+8+7}{26}[/tex]
[tex]\overline x = \frac{171}{26}[/tex]
[tex]\overline x = 6.58[/tex] --- approximated
The sample variance is then calculated using:
[tex]s^2 = \frac{\sum(x_i - \overline x)^2}{n-1}[/tex]
This gives:
[tex]s^2 = \frac{(5-6.58)^2+(8-6.58)^2+(3-6.58)^2+(8-6.58)^2+..............+(8-6.58)^2+(8-6.58)^2+(7-6.58)^2}{25-1}[/tex]
[tex]s^2 = \frac{88.3464}{25}[/tex]
[tex]s^2 = 3.53[/tex] --- approximated
(c) Standard Deviation.
This is calculated as:
[tex]s = \sqrt{s^2[/tex]
Substitute 3.53 for [tex]s^2[/tex]
[tex]s = \sqrt{3.53}[/tex]
[tex]s = 1.88[/tex] --- approximated
(d) No, it can not be used because the selected sample is too small to represent the total population and as such the result of the measure of variations can not be used.

A line with a slope of 0.20 passes through
the point (1.25, -17.5). What is the
equation of the line in slope-intercept form?
Plss help ASAP I’ll give anything
Answers
Answer:
y=0.2x-20
Step-by-step explanation:
1) the common view of the line in the slope-intercept form is:
y=s*x+i, where s - the value of the slope (it is 0.2 according the condition), i - the value of intercept (to be calculated);
y=0.2*x+i.
2) if to substitute the given coordinates (1.25;-17.5) into the common view, then:
-17.5=1.25*0.2+i;
it is possible to calculate the value of 'i': i= -20.
3) if the slope=0.2, the intercept= -20, then the required equation of the line is:
y=0.2x-20.
