Answer:
Option d.
Step-by-step explanation:
we know that
The graph of a continuous probability distribution is a curve. Probability is represented by area under the curve.
The curve is called the probability density function (abbreviated as pdf).
We use the symbol f(x) to represent the curve
therefore
The probability density function f(x) represents . the height of the function at x.
In 4 days Bryn sells 24 tickets (50-26)
So in 1 day he sells 6 tickets --> B is right
The +33 in the equation means, that Eddie sold 33 tickets oon the first day
--> So C.) and D.) are right
When you replace the x in the equation with 1, you'll get the tickets, that eddie sold on the first day. --> y = 5 *(1)+33 = 38
38 tickets - 33tickets = 5 tickets ( the rise)
-->A.) is wrong, because Bryn sold two tickets more as Eddie per day
B. 33.5 is your answer
First you want to add 12+4 because it is in parentheses
8.5+16x2-7
Then you multiply 16 by 2
8.5+32-7
Then you add 8.5 to 32
40.5-7
Then you subtract 7 from 40.5 giving you your answer
33.5
Answer:
70.
Step-by-step explanation:
Let x be the required number.
We are asked to find the number whose 90% equals to 63.
We can represent our given information in an equation as:
Now, we need to solve for x.
Therefore, 90% of 70 is 63.
