Step-by-step explanation:

171 km/h

travel distance = 855 km

855 / 171 = 5 hours

it took him 5 hours to fly the 855 km (theoretically to the hospital).

normally, with a plane, you can't land on or at a hospital. you would need a helicopter to be able to do that.

so, he could only fly to a nearby airport, and then travel from there to the hospital. but we have no information about that.

Question 12.12. In 2010, the population of a city was 65,903. It was expected to grow at a rate of 0.7% each year.
postnew [5]

y=Ce^{kx}

k=0.7%=0.007

65903=Ce^{.007(0)} \\  65903=Ce^0 \\  65903=C(1) \\ C = 65903

y=65903e^{0.007(2027-2010)}\\y=65903e^0.229 \\ y = 74231.157

The best answer is 74,200

Choose all which define events A and B as independent events.
Firlakuza [10]

There are 2 answers: Choice 1, Choice 4

=======================================

Why is this? Because we use the rule

P(A & B) = P(A) * P(B)

which only works if events A and B are independent

----

For the first answer choice,

P(A) * P(B) = 0.6*0.4 = 0.24 = P(A & B)

so that matches.

The same applies to the fourth answer choice as well

P(A) * P(B) = 0.3*0.2= 0.06 = P(A & B)

----

The other answer choices don't match up.

The second answer choice has

P(A) * P(B) = 0.3*0.4 = 0.12 but that doesn't match with the 0.70 given

Similarly for the third answer choice,

P(A) * P(B) = 0.5*0.1 = 0.05 which doesn't match with the 0.60

If two are supplementary and one of the angles measure 62 what is the measure of the other angle
Juli2301 [7.4K]
Supplementary angles add to equal 180 degrees. If two angles are supplements of each other and one of the angles measures 62 degrees, you can set its sum with the unknown angle, x, equal to 180 and solve for the unknown angle x.

Equation:
180 = x + 62

Subtract 62 from both sides:
118 = x

Answer:
The measure of the other angle is 118°.
