It has to be red since there are the most red marbles in the bag
The total cost is the dependant variable and the number of tickets along with flat out price is the independent variable.
The equation would be y = 1.25x + ?
You would insert 25 for x which equals 31.25 and insert 43.75 for y.
43.75 = 31.25 + ? Then subtract 31.25 from both sides of the equation and you would get....
12.5 = ?
That is your flat rate to get in to the fair
Answer:
C and D
Step-by-step explanation:
So basically when u square -5 or +5, u get 25 either way
And since the square root of x is greater than or equal to 25, u can use both of them for answers.
Answer:
A function can have many x values for a given y value and still be a function but it cannot have many y values for a given x value. You can easily test this by graphing the equation and doing the vertical line test by seeing if a vertical line will intersect the graph only once at all x values, if it passes it is a function. In short what you have here is a function

Step-by-step explanation:
The owner already knows that the limit for the average time delivered pizzas is 38 minutes. So we conclude
1.-The resulting mean from sample data ( x ) ( 27 customers) need to be smaller than 38 minutes, any value of sample above 38 minutes means more time for the delivery action and will indicate a failure for the future project
2.-As sample size is smaller than 30 the test has to be t-student one tail test to the left
Test hypothesis
Null hypothesis H₀ x = 38
Alternative hypothesis Hₐ x < 38
We should test at a significance level α = 0,05 (α = 5%)
If the result of the test is to accept H₀ delivery project won´t be implemented, if on the other hand, H₀ is rejected then in the condition of the alternative hypothesis we accept Hₐ the sample indicates that we have a smaller average time than 38 minutes.
