Answer:
Step-by-step explanation:
First, let's find how many total items there are in the box.
If there are 20 oranges and 10 grapes, then there are items in the box.
Now, if there are 10 grapes in this box, we know that the probability of picking a grape is because the total is the denominator and the number of items for that selection is the numerator.
We can simplify this fraction down to .
Hope this helped!
Answer:
x>-9/20 or x > -0.45
Step-by-step explanation:
simplify both sides of the inequality:
-20x-10<-1
add 10 to both sides of the inequality:
-20x<9
divide both sides of the inequality by -20:
x>-9/20
divide to discover the decimal value:
-9/20= -0.45

What equation describes this variation?
z = kxy
What is the constant of variation?
k = 5
When x = 1 and y = –2, z =
-10
Step by Step Explanation:
With the equation z = kxy and the values for z, x, and y, we can find k.
z = kxy
-75 = (k) (3) (-5)
-75 = (k) (-15)
5 = k
k = 5 (final answer).
To check our work, we just enter all of the values and make sure it adds up.
z = kxy
-75 = (5)(3)(-5)
-75 = 15(-5)
-75 = -75
correct!
Do the same to find the answer for the next part to get -10.
