Start with y = 2x. Subst. a for x and a+sqrt(3) for y:
a+sqrt(3) = 2a
Subtracting a from both sides: sqrt(3) = a
We start by showing the position of the first quartile, Q1 on the normal distribution graph. Q1 happens at 25% of the data.
The graph is shown below
We are interested in the area to the left of Q1 and we know that the probability is 0.25
We can find out the value of z-score from the table as shown below
The z-score when p=0.25 is 0.68
then changing this z-score into the actual value
Answer:
67 tickets
hope it helps
Step-by-step explanation:
if they need to raise $1000 dollars and each ticket is $15 to find how many tickets need to be sold in order to meet their goal you would have to divide 1000 by 15 and you will get the number of tickets that need to be sold
1000 ÷ 15 = 66.6
so we would round in order to meet our goal so they need to sell 67 tickets
And if you wanna check your work you can multiply 67 by 15 and you should get the amount to reach their goal
67 x 15 = $1005
