Evaluate 5 remainder 5

ExtremeBDS [4]

The remainder is 5. To calculate this, first, divide 599 by 9 to get the largest multiple of 9 before 599. 5/9 < 1, so carry the 5 to the tens, 59/9 = 6 r 5, so carry the 5 to the digits. 59/9 = 6 r 5 again, so the largest multiple is 66. Multiply 66 by 9 to get 594, and subtract this from 599 to get 5, the remainder.

A bag contains 6 red marbles, 10 white marbles, and 7 blue marbles. You draw 4 marbles out at random, without replacement. What

Lapatulllka [165]

Answer:

3/1771

Step-by-step explanation:

Probability is the chance or likelihood that an event will occur.

Probability = expected outcome/total outcome

Total outcome = total number of marbles

Total outcome = 6+7+10 = 23marbles

If four marbles are drawn, the probability that they are all red is expressed as;

Pr(picking the first red marble) = 6/23

Since it is without replacement, the total marble becomes 22

Pr(picking the second) = 5/22

Pr(picking the third marbles = 4/21

Pr(picking the 4th marble) = 3/20

Note that the number of red marbles keep reducing and the total marble keep reducing as well.

Pr(picking the 4marbles) = 6/23×5/22×4/21×3/20 (we multiplied because or is an independent events)

Pr(picking the 4marbles) = 360/212520

Pr(picking 4 red marbles) = 72/42504 =36/21,252

= 9/5313

= 3/1771

Hence the probability of picking 4 marbles at random without replacement is 3/1771

The length of a rectangular garden is 10 yards and its width is 10 feet. What is the perimeter of the garden in feet???? This wa

AVprozaik [17]

Answer:

80 feet.

Step-by-step explanation:

Given:

The length of a rectangular garden is 10 yards and its width is 10 feet.

To find:

Perimeter of the garden in feet ?

Solution:

Length = 10 yards

1 yard = 3 feet

10 yards = 3 $\times$ 10 = 30 feet

Breadth = 10 feet

Now, as we know:

$Perimeter\ of\ rectangle=2(length+breadth)$

$=2(30+10)\\ \\ =2(40)\\ \\ =80\ feet$

Hence, the perimeter of the garden is 80 feet.
