Answer:

Answer: 5 oz

Step-by-step explanation:

A factory produces 1000 bottles of pasta sauce in a day. Fifty bottles are selected at random to determine if they weigh the correct amount. The factory rejects bottles that are over or under the correct weight.One bottle is under weight, 46 bottles are the correct weight, and 3 bottles are over weight.

Based on this random sample, approximately how many bottles will the factory reject from the day's production?

A.4

B.20

C.60

D.80

Answers

Answer:

option: D is correct.

Step-by-step explanation:

The random sample is given of 50 bottles which is depicted as:

1 bottle under weight

46 bottles correct weight

3 bottles over weight

As the bottles which are under weight and over weight are rejected.

that means out of 50: 4 bottles are rejected.

Now we have to find out the number of bottles rejected out of the 1000 bottles.

As 1000 is 20 times of 50.

Hence the number of bottles rejected will also get multiplied by 20.

Hence total number of bottles rejected=80.

Hence, option D is correct.

Jack wants to know how much water a spherical ball can hold with a radius of 8 cm?

Answers

Answer: 2144.7 cm^3

Step-by-step explanation: You need to find the volume of a sphere with a radius of 8 cm if you want to know how much water Jack can hold.

V = 4/3 π r^3 = 4/3 * π * 8^3 ≈ 2144.7 cm^3

Write a system of linear equations that has (-4, 8) as the solution. Once you have made your system of equations, solve it algebraically to show that you do indeed get the solution (-4, 8).

Answers

Answer:

See below

Step-by-step explanation:

(-4, 8) has to be the solution.

1st equation: -4x+8y = 1

2nd equation: 8x - 4y = 1

These should work. Do the matrix-substitution combo method to see:

-4  8  1

.8 -4  -1

Reduce and and matrix-substitution combo:

1 0 -4

0 1  8

The reduced eckerd form of the matrix shows that the solutions are (-4, 8)

Therefore it -4x + 8u = 1 and 8x - 4y = 1 are the two equations for the system.
