Good evening

Answer:

a) the cost of one apple is €0.9

b) the cost of one pineapple is €5.4

c) the cost of two pineapples and six apples is €16.2

Step-by-step explanation:

Consider P the price of a pineapple

A the price of an apple

A pineapple costs six times as much as an apple means P = 6A

Mum paid €7.20 for one pineapple and two apples means P + 2A = 7.20

then

6A + 2A = 7.20

then

8A = 7.20

then

A = €0.9

Since P = 6A then P = 6×(0.9) = €5.4

the cost of two pineapples and six apples

= 2P + 6A

= 2P + P

= 3P

= 3×(5.4)

= €16.2

A company with n employees publishes an internal calendar, where each day lists the employees having a birthday that day. What i

lutik1710 [3]

Answer: $1-(\frac{364}{365})^n$

Step-by-step explanation:

Binomial probability formula :-

$P(x)=^nC_xp^x(1-p)^x$ , where P(x) is the probability of getting success in x trials, n is the total number of trials and p is the probability of getting success in each trial.

We assume that the total number of days in a particular year are 365.

Then , the probability for each employee to have birthday on a certain day :

$p=\dfrac{1}{365}$

Given : The number of employee in the company = n

Then, the probability there is at least one day in a year when nobody has a birthday is given by :-

$P(x\geq1)=1-P(x$

Hence, the probability there is at least one day in a year when nobody has a birthday = $1-(\frac{364}{365})^n$

What is the solution to this system of equations (5z +y=2 ( 47 +y=5

prisoha [69]

Answer:

Z = 8.8 Y = - 42

Step-by-step explanation:

Y = 2 - 5Z

Y = 5 - 47

2 - 5Z = 5 - 47

- 5Z = - 44

5Z = 44

Z = 8.8

Y = 2 - 5 (8.8)

Y = 2 - 44

Y = - 41

Y = 5 - 47

Y = - 42
