Mumz [18]

Answer:

Joy is correct

Step-by-step explanation:

we know that

1 cup=1/2 pint

step 1

Convert pint to cups

Divide 4/5 pint by 1/2 to convert to cups

so

\frac{4}{5}:\frac{1}{2}=\frac{8}{5}\ cups

step 2

Convert to mixed number

\frac{8}{5}\ cups=\frac{5}{5}+\frac{3}{5}=1\frac{3}{5}\ cups

therefore

Joy is correct

LUCKY_DIMON [66]
Let success be that a plant dies in the winter and failure be that a plant survives the winter, then
 p = 0.05, q = 1 - 0.05 = 0.95

a.) P(1 or more will not survive the winter) = 1 - P(all will survive the winter) = 1 - P(0) = 1 - 10C0 (0.05)^0 (0.95)^10 = 1 - 1(1)(0.5987) = 0.4013

b.) P(all will survive) = P(none will die) = P(0) = 0.5987

Three square flower beds with side of 2m are dug in a rectangular piece of land whose length is 5.2 m and width is 4.8 m. What i
belka [17]

Answer: 12.96 m²

Step-by-step explanation:

The area of the piece of land that the flower beds were dug in is:

= Length * width

= 5.2 * 4.8

= 24.96 m²

The flower beds were 3 in number and all had the shape of a square.

Their area is:

= 3 * (Length * width)

= 3 * ( 2 * 2)

= 3 * 4

= 12 m² for all three flower beds

Remaining land:

= 24.96 - 12

= 12.96 m²
