Answer:
It should be red or green 125 times
Step-by-step explanation:
The first thing to do here is to calculate the probability of selecting a red or a green marble
Total number of marbles = 7 + 3 + 2 + 8 = 20
Probability of selecting a red marble is 7/20
Probability of selecting a green marble is 3/20
The probability of selecting a red or a green marble = Probability of selecting a red marble + Probability of selecting a green marble = 7/20 + 3/20 = 10/20 = 1/2
Now our selection spans 250 times, the number of times it should have been a green or a red marble = The probability of selecting a green or a red marble * number of selection times = 1/2 * 250 = 125 times
Answer:
c
Step-by-step explanation:
divide it by 5x. the rest of this is all just to fill up the space that I have to have to put the answer you can ignore it
Answer:
4 /25
Step-by-step explanation:
Given that :
Cup of vinegar used per recipe = 1/5 cup
Amount of vinegar to be used for 4/5 of a recipe ;
1 cup recipe = 1/5 cup vinegar
4/5 cup recipe = x
Cross multiply :
x = 1/5 * 4/5
x = 4/25 cup
Hence, Sandeep will use 4/25 cup of vinegar
The formula for slope is
Slope = Rise / Run = Risers / Treads
Slope = 7.75 in /10 in = 0.775
The slope Is 0.775.
The vertical distance is not continuous, thus it is
discrete. A discrete function only allows certain points in the interval. When
you walk up or down the stairs, the vertical distances are not continuous
because of the treads. You cannot stay also mid-air, so it should be discrete.
An example of a continuous function would be when you walk up or down an
inclined plane.
S = the number of student tickets sold a = the number of adult tickets sold The drama class sold 25 more student tickets than adult tickets to the fall play s = a + 25 The class collected $660 from ticket sales: 6s + 3a = 660 divide both sides by 3 2s + a = 220 by solving the system of equations s = a + 25 2s + a = 220 we find s = 81.67 student tickets a = 56.67 adult tickets
