The area of a triangle is 1/2 the base times the height.
The base is 15 and the height is 13.

Area = 1/2 x 15 x 13 = 97.5 sq. units.
The answer is A.

Answer:

The correct option is A.

Step-by-step explanation:

The area of a triangle is

$A=\frac{1}{2}\times base \times height$

From the given figure it is clear that the base of the triangle is 15 units and the height of the triangle is 13 units.

The area of the triangle is

$A=\frac{1}{2}\times 15 \times 13$

$A=97.5$

The area of triangle is 97.5 square units. Therefore option A is correct.

The exponential distribution can be used to solve Poisson-type problems in which the intervals are not time. The Air Travel Cons

frutty [35]

Answer:

a) $P(X \ge 490) = 0.628$

b) $P(X \leq 190) = 0.165$

Step-by-step explanation:

a) This is an exponential distribution question since it is a poisson type problem

Mean rate is 0.95 per 1000 passengers

Mean rate, $\lambda = 0.95/1000$

$\lambda = 0.00095$ per passenger

Probability that at least 490 passengers will have their baggage handled properly before the next mishandling occurs :

$P(X \ge x) = e^{- \lambda x}$

$P(X \ge 490) = e^{-490 * 0.00095}$

$P(X \ge 490) = e^{-0.4655}\\P(X \ge 490) = 0.628$

b) Probability that the number will be fewer than 200 passengers

$P(X \leq 190) = 1 - P(X \geq 190)\\P(X \leq 190) = 1 - e^{-190 \lambda} \\P(X \leq 190) = 1 - e^{-190 *0.00095}$

$P(X \leq 190) = 1 - 0.835\\P(X \leq 190) = 0.165$

Use the formula F = 1.8C + 32 to convert -10C into Fahrenheit

photoshop1234 [79]

Well since the value of C has been given to you, plug it into the equation.

F = 1.8(10) + 32
F = 18 +32
F = 50

The temperature in Fahrenheit would be 50 degrees.

Lines AB and CD and are parallel. Find the measures of the three angles in triangle ABF.

Airida [17]

Answer: ∠B = 42° ∠A = 23° ∠F = 115°

Step-by-step explanation:

∠B≅∠C alternate interior angles 42°

∠CDF is supplementary to ∠CDE,

so m∠CDF = 23° and ∠FAB≅∠CDF so m∠FAB= 23°

<em>also ∠A ≅ CDE corresponding angles 157° ∠FAB is suplementary to ∠A </em>

<em>so 180 - 157 = 23 gives the m∠FAB</em>

The sum of the angles of a triangle is 180°, so m∠AFB = 180 -(23 +42)

180- 65 = 115 = m∠F
