Answer:

1600 items should not be defective

Step-by-step explanation:

To determine the number of items that are not defective, we multiply the number of items we have by the probability that they are not defective.

Not defective items = items * probability

                                 = 2000 * 4/5

                                    1600

UNO [17]

Answer:

x = 80

Step-by-step explanation:

x + 30 = 110 (opposite sides are congruent/equal)

x = 110 - 30 (subtract the 30 from both sides to get X by itself)

x = 80 (simplify)

At the end of a party, 3/4 cup of dip is left. Jim divides 4/5 of the leftover dip equally between 2 friends. How much dip does
Rudik [331]
First, we need to find the amount of dip that was divided amount the two friends.

We know that it is 4/5 of the left dip 
therefore:
amount divided among the two friends = (4/5) x (3/4) = 3/5 of the original amount of dip.

This amount is divided among two friends,
therefore:
amount that each friend gets = (3/5) / (2) = 3/10 = 0.3 of the amount of dip

Hannah is designing containers to hold 300 cm3 of juice. Which container is more efficient?
Lubov Fominskaja [6]

Answer:

a) 2nd container is more efficient and contains the elements for a container.

b) The cylinder has a........A)Smaller surface area B)bigger C)equal

And will cost.....A)Less to produce B)more C)The same

Step-by-step explanation:

a) The 2nd container has these elements:

Width 20.5cm

Length 6.5cm

side 3.25cm

So, the volume in cubic cm is 20.5 x 6.5 x 3.25 = 433cm3.

This container can hold the 300cm3 of juice.

b) A cylinder is a geometric solid common in everyday life.  Examples of a cylinder are soup cans, food tins, drink cans, candles, toilet paper rolls, cups, aerosol cans, flower vases, test tubes, fire extinguishers, plant containers, salt shakers and pencil holders.  The two ends are called bases, and are usually circular.  Though, they can take other shapes.  When a cylinder is unrolled and flattened out, the side is actually a rectangle.

The surface area of a cylinder is the surface area of each end plus the surface area of the side.  The mathematical formula is 2π * r2, where π is the pie and r is the radius of the end and r2 is r squared..

P’(rolling a number less than five and landing on tails)
Ksenya-84 [330]

Answer:

P’(rolling a number less than five and landing on tails) = 1/3

Step-by-step explanation:

dice has 6 numbers and you only want 4 of them, so you have a 4 in 6 chance of doing that which is equal to 4/6 or 2/3

a coin has 2 side so the chance of getting tails is 1 in to or 1/2

therefore the probability of getting a number less than 5 and a tails is

4/6 times 1/2 = 4/6 x 1/2 = 4/12 = 1/3

or you can do it this way:

2/3 times 1/2 = 2/3 x 1/2 = 2/6 = 1/3
