Answer:
hypotenuse= 2
Step-by-step explanation:
the triangle is equal tow side so it is two side =5 cm
then the hypotenuse by Phitagors theory the triangle hypotenuse =
= 2
She has $12,488 in savings
Step-by-step explanation:
Ariana plans to use $260 less than three-fourths of savings to buy a car.
If the purchase price of the car is 9,340, we need to find how much
she has in savings
To find the savings
- Assume that she has $x in savings
- Write an equation of x
- Solve the equation to find x
∵ She has $x in savings
∵ She plans to use $260 less than three-fourths of savings
- Three-fourths means
and less than means subtract
∴ She plans to use
x - 26
∵ The purchase price of the car is 9,340
- Equate the expression of x by 9,340
∴
x - 26 = 9,340
Now let us solve the equation
∵
x - 26 = 9,340
- Add 26 to both sides
∴
x = 9,366
- Divide both sides by
∴ x = $12,488
She has $12,488 in savings

Answer:
55.32% probability that a late package was delivered by express delivery service 2
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Late delivery.
Event B: Service 2 was used.
A certain company sends 35% of its overnight mail parcels via express delivery service 1 and the rest by express delivery service 2.
100 - 35 = 65%.
So 
Service 2 has a record of 2.0% of packages being delivered late.
This means that 
Probability of a late delivery.
35% from service 1. Of those, 3% are late.
65% from service 2. Of those, 2% are late.
So

What is the probability that a late package was delivered by express delivery service 2
55.32% probability that a late package was delivered by express delivery service 2
Answer:
The measure of an interior angle of a regular 12-gon is 150°.
Hence, option 'C' is correct.
Step-by-step explanation:
We need to determine the measure of an interior angle of a regular 12-gon.
- We know that the number of sides in a regular 12-gon = n = 12
Thus,
Using the formula to determine the measure of an interior angle of a regular 12-gon is given by
(n - 2) × 180° = n × interior angle
substitute n = 12
(12 - 2) × 180 = 12 × interior angle
10 × 180 = 12 × interior angle
Interior angle = (10 × 180) / 12
= 1800 / 12
= 150°
Therefore, the measure of an interior angle of a regular 12-gon is 150°.
Hence, option 'C' is correct.
