Answer:

x = ± 4/5

Step-by-step explanation:

25 x^2 = 16

Divide each side by 25

25 x^2 /25 = 16 /25

x^2 = 16 /25

Take the square root of each side

sqrt(x^2) = ±sqrt(16/25)

We know that sqrt(a/b) = sqrt(a)/ sqrt(b)

x = ±sqrt(16) / sqrt(25)

x = ± 4/5

How to find the point slope form with the slope of 3 and the point of -2/6
Levart [38]

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \:y-6 = 3(x + 2)

____________________________________

\large \tt Solution  \: :

Equation of line in point - slope form :

\qquad \tt \rightarrow \:y-y_1 = m(x - x_1)

  • \tt  \:m = slope=3

  • \tt y_1 = y \:  \: coordinate \:  \: of \:  \: point = 6

  • \tt  \:x_1 = x \:  \: coordinate \:  \: of \:  \: point =  - 2

Here :

\qquad \tt \rightarrow \:y - 6 = 3(x -  ( - 2))

\qquad \tt \rightarrow \:y - 6 = 3(x +  2)

What is the interquartile range of the data set? Enter the answer in the box. Key: 1|5 means 15
Aneli [31]
First of all we have to arrange the data in ascending order as shown below:

28, 40, 43, 43, 45, 50, 50

Total number of values = 7

Since the number of values is odd, the median will be the middle value i.e. 4th value which is 43. Median divides the data in two halves:

1st Half = 28, 40, 43
2nd Half = 45, 50, 50

Q1 or the First Quartile is the middle value of the lower or 1st half which is 40.
Q3 or the Third Quartile is the middle value of the upper or second half, which is 50.

IQR or the Inter Quartile Range is the difference of Q3 and Q1.

So, IQR= Q3 – Q1 = 50 – 40 = 10

Thus, IQR for the given data is 10
