Answer:

nope

Step-by-step explanation:

A-(b-c)=(A-b)-c

let a be 2, b be 3 and c be 4

2-(3-4)=(2-3)-4

2-(-1)=(-1)-4

2+1=-1-4

3=-5

therefore, association is not goot under subtraction

Answer:

$\sqrt{13}$

Step-by-step explanation:

A is the hyp. And b/c are the sides

A²=b²+c²=3²+2²=9+4=13

Now take the square root of 13 as the answer

Population density is the number of people per unit of area. What is the population density of a state that has 1627260 people i

g100num [7]

If state has 1627260 people and 1490 square miles, then we divide the number of people by the area and we get the density per square mile.

1627260 / 1490 = 1092,120805369128

After rounding it to the nearest whole number we get 1092.

The answer: In such a state 1092 people live in a square mile.

A doctor studies the known cancer patients in a certain town. The probability that a randomly chosen resident has cancer is foun

Alex777 [14]

Let the event 'has cancer' be C, and the event 'works for Ajax' be A.
P(C) = 0.0019. P(A) = 0.28
The events A and C are independent if P(C|A) = P(C).
P(C|A) = 0.0019 = P(C).
Therefore the answer is YES.

If angle EFH(5x+1)’ angle HFG(62 degrees) and angle EFG (18x+11) find each measurement

zloy xaker [14]

Answer:

∠EFH = 21°

∠HFG = 62°

∠EFG = 83°

Step-by-step explanation:

The diagram showing the angles has been attached to this response.

From the diagram, it can be deduced that;

Angle EFG = angle EFH + angle HFG

=> ∠EFG = ∠EFH + ∠HFG -------------------(i)

From the question:

∠EFH = (5x + 1)° -------------(ii)

∠HFG = 62° -------------(iii)

∠EFG = (18x + 11)° -------------(iv)

Substitute these values into equation (i) as follows;

(18x + 11) = (5x + 1) + 62

=> 18x + 11 = 5x + 1 + 62

Collect like terms and solve for x

18x - 5x = 1 + 62 - 11

13x = 52

x = 4

Now, to get each measurement, substitute x = 4 into each of equations (ii) - (iv)

∠EFH = (5x + 1)°

∠EFH = (5(4) + 1)°

∠EFH = (20 + 1)°

∠EFH = 21°

∠HFG = 62° [Does not depend on x]

∠EFG = (18x + 11)°

∠EFG = (18(4) + 11)°

∠EFG = (72 + 11)°

∠EFG = 83°

Conclusion:

∠EFH = 21°

∠HFG = 62°

∠EFG = 83°
