Answer:
Red is 3/10
yellow is 1/3
Step-by-step explanation:
since there is 10 marbles all together it will be out of 10
and since there is 3 red marbles the probability is 3/10
but when you take out one of the marbles the total amount of marbles in the bag is 9. since there is 3 yellow marbles in the bag it would be 3/9 which can be simplified to 1/3
Step-by-step explanation:
So you would need to find a common denominator to add the fractions together first, and the closest would be 40
5/8 turns into 25/40 because we times the bottom and the top by 5 to get the LCD (least common denominator)
6/10 turns into 24/40 when times by 4 for the LCD of 40
Then add them together: 25/40 + 24/40 = 49/40
And since 1 could also be written as 40/40 since that is the whole number, this means the following expression is true.
49/40 > 40/40 (or 1)
Nine hundred thirteen thousand

B) Test statistics 1.96
Step-by-step explanation:
Null hypothesis is a statement that is to be tested against the alternative hypothesis and then decision is taken whether to accept or reject the null hypothesis. In the given scenario the test is to identify whether there is any difference in annual goals between western division and eastern division. The null hypothesis will be the Goals of western are equal to eastern division and alternative hypothesis will be Goals of western are not equal to eastern division.
Answer:
The vertex of this parabola is 
Step-by-step explanation:
One way of finding the x-coordinate of the vertex of a parabola is by using the equation 
From the function
, we can see that

This means that

So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.

Thus, the vertex of this parabola is
