In the U. S., approximately 8.3% of the population has diabetes. Maryland's rate of diabetes for its residents is 12% higher than the national average. What is the rate of diabetes in the state of Maryland? *

9.30%

Step-by-step explanation:

Given;

The average rate in the national average N = 8.3%

The average rate in Maryland R = 12% higher than national

R = N + 12% of N

R = N + 0.12N

R = 1.12N

R = 1.12 × 8.3%

R = 9.296%

R = 9.30%

Rate of diabetes in Maryland = 9.30%

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

just keep asking questions until you have a better understanding.
