Solve (x - 3)^2+7=97, where X is a real number. Round your answer to the nearest hundredth.

Eddi Din [679]

Answer:

x ≈ - 6.49, x ≈ 12.49

Step-by-step explanation:

Given

(x - 3)² + 7 = 97 ( subtract 7 from both sides )

(x - 3)² = 90 ( take the square root of both sides )

x - 3 = ± $\sqrt{90}$ ( add 3 to both sides )

x = 3 ± $\sqrt{90}$

Then

x = 3 - $\sqrt{90}$ ≈ - 6.49 ( to the nearest hundredth )

x = 3 + $\sqrt{90}$ ≈ 12.49 ( to the nearest hundredth )

The table shows the length of hospital stay for 21 randomly selected adult patients. What is the interquartile range of this dat

Lorico [155]

To calculate it, first order your data points from least to greatest, then determine your first and third quartile positions by using the formulas (N+1)/4 and 3*(N+1)/4 respectively, where N is the number of points in the data set.

after you do that then say IQ=Q3-Q1

Answer:

Perimeter of Triangle: $6x+15$

$x=12.5$

Step-by-step explanation:

The perimeter is the sum of all of the sides of the triangle.

Hence, the perimeter $=3x+3x+15=6x+15$

Since the perimeter is 90, $6x+15=90$ .

Subtract 15 from both sides:

$6x+15-15=90-15$

$6x=75$

Divide both sides by 6:

$\frac{6x}{6}=\frac{75}{6}$

$x=12.5$
