First divide 308 by 5 then you get 61.6 so 61 5s go into 308
105/4
because the ratio of the perimeter of the first to second is 4/3
Answer:
As to sidea are equal therefore it is an isosceles triangle .
therefore
,80+x+x=180
80+2x=180
2x=100
x=50
Cost of one pretzel is $2.5 and cost of one ice cream is $4.5
Step-by-step explanation:
Let,
Cost of pretzel = x
Cost of ice cream = y
According to given statement;
the cost of a pretzel is $2 less than the cost of some ice cream.
x = y - 2 Eqn 1
five ice creams cost the same as nine pretzels.
9x = 5y Eqn 2
Putting value of x from Eqn 1 in Eqn 2
Dividing both sides by 4
Putting y=4.5 in Eqn 1
Cost of one pretzel is $2.5 and cost of one ice cream is $4.5

Answer:
Correct option is b. Procedure results in a binomial distribution.
Step-by-step explanation:
Consider that <em>X</em> is Binomial random variable. The properties that are satisfied by <em>X</em> are:
- There are <em>n</em> independent trials.
- Each trial has only two outcomes: Success & Failure.
- Each trial has the same probability of success.
Suppose a roulette wheel is spun and the number of times the ball lands on '16' is observed.
If the random variable <em>X</em> is defined as the number of times the ball lands on '16', then the random variable <em>X</em> follows a Binomial distribution.
Because,
- Each spin is independent of each other
- Success: The ball lands on '16'
- Failure: The ball does not lands on '16'
- The probability of the ball landing on '16' is for each trial.
Thus, the correct option is b. Procedure results in a binomial distribution.
