In a certain lottery game, 34 numbers are randomly mixed and 7 are selected. A person must pick all 7 numbers to win. Order is n

777dan777 [17]

Answer:

p(win)=0.00094

Step-by-step explanation:

-This is a factorial/combination question.

-The probability is calculated using the formula:

$p=\frac{x!}{_nC_x}\\\\$

Where:

$x$ is the number of successful picks

$n$ is the total number of picks

Therefore, we calculate the probability as follows;

$Pp=\frac{x!}{_nC_x}\\\\=\frac{7!}{_{34}C_7}\\\\=0.00094$

Hence, the probability of winning is 0.00094

Write y = –2/5x – 3 in standard form using integers.

guajiro [1.7K]

The standard form is:
a x + b y = c
y = - 2/5 x - 3 / *5 ( we will multiply both sides of an equation by 5 )
5 y = - 2 x - 15
Answer:
2 y + 5 y = - 15
