A certain delivery service offers both express and standard delivery. 75% of parcels are sent by standard delivery, and 25% are

zloy xaker [14]

Answer:

The probability that the parcel was shipped expressed and arrived the next day = 0.2375 .

Step-by-step explanation:

We are given that a certain delivery service offers both express and standard delivery.

Let Proportion of parcels sent by standard delivery, P( $A_1$ ) = 0.75

Proportion of parcels sent by express delivery, P( $A_2$ ) = 0.25

Let <em>event B = Parcel arriving the next day</em>

Also, Probability of parcel arriving the next day given it was sent through standard delivery, P(B/ $A_1$ ) = 0.8

Probability of parcel arriving the next day given it was sent through express delivery, P(B/ $A_2$ ) = 0.95

Now, Probability that the parcel was shipped expressed and arrived the next day = P( $A_2$ ) * P(B/ $A_2$ ) = 0.25 * 0.95 = 0.2375 .

The length of the base of an isosceles triangle is x. The length of a leg is 3x-5. The perimeter of the triangle is 39. Find X.

frozen [14]

Answer:

x = 7

Step-by-step explanation:

In an isosceles triangle, both legs are always congruent. The length of one leg is given, and the other leg has to be the same. The perimeter of this triangle can be written as:

$x+(3x-5)+(3x-5)=39$
