Answer:

y=4x-6

Step-by-step explanation:

to find the slope it's ((y1-y2)/(x1-x2) which in this case is (10-(-6))/(4-0) which is 16/4 aka 4

the y intercept is already given at point (0,-6)

so to write the equation is y intercept form: its y =4x-6

Solve y=1/4x+5 for x

Elden [556K]

Y = 1/4x + 5....multiply everything by 4 to get rid of the fraction
4y = x + 20...now subtract 20 from both sides
4y - 20 = x <==

X^2 + 4x + 4 = 10<br>please help!! I missed class! show steps!

lina2011 [118]

Answer:

x = √(10) - 2, -√(10) - 2

Step-by-step explanation:

x² + 4x + 4 = 10

factor:

(x + 2)² = 10

take square root of both sides:

x + 2 = ±√(10)

split into 2 equations:

x + 2 = √(10) x + 2 = -√(10)

solve both equations and collect solutions:

x = √(10) - 2, -√(10) - 2

1. The number of customers in a restaurant during the peak hour of each day for a month varied

Gnom [1K]

Step-by-step explanation:

First we must calculate the interquartile range (IQR), using this equation:

$IQR = Q_{3} - Q_{1}$

Based on the information provided we fill in:

$IQR = 58 - 45$

$IQR = 13$

In order to find what the range for the data set is we need to use the Interquartile Rule:

$Q_{1}-1.5$ × $IQR\\$

$Q_{3}+1.5$ × $IQR\\$

$1.5$ × $13 = 19.5$

Now we plugin in:

$45 - 19.5 = 25.5\\$

$58 + 19.5 = 77.5$

Any number below 25.5 is a possible outlier and any number above 77.5 is a possible outlier.

Answer:

Based on the results of the calculations, 25 could be a possible outlier in the data set.
