The percentage error is 11.1%

<h3>What is percentage error?</h3>

Percentage error is simply the difference between the exact and the estimated values as a percentage

The given parameters are:

Estimate = 45
Actual = 50

The percentage error is then calculated as:

$\% E = \frac{50 - 45}{45} \times 100\%$

Evaluate the difference

$\% E = \frac{5}{45} \times 100\%$

So, we have:

$\% E = \frac{500}{45} \%$

$\% E = 11.1\%$

Hence, the percentage error is 11.1%

Mary owned n sheep and Sam had exactly 4 times as many sheep as Mary.

Veseljchak [2.6K]

Answer:

The least value of n is, 9.

Step-by-step explanation:

Mary(M) owned the number of sheep is n i.e, M = n sheep

Sam(S) had exactly four times as many sheep as Mary , i.e, S = 4 n sheep

As per the given condition Mary buys 17 extra sheep

Now, Mary has total number of sheep, M = n +17 sheep

And Sam sells 8 of his sheep that means he has now,

But, Sam still has more sheep than Mary i.e,

Solve an inequality:

Add 8 both sides we get;

Simplify:

Now, subtract n from both the side, we get;

Simplify:

or

Since n is the number of sheep in integer,

then the least value of n is, 9.

Since the number of green and blue marbles is the same, and the number of green marbles is divisible by 8, and the blue marbles by 6, the number of green marbles (and of the blue marbles) must be a multiple of both 6 and 8. The least common multiple of 6 and 8 is 24. So there can be either 24 blue and 24 green marbles, leaving 52 for red and yellow, or 48 blue and 48 green marbles, leaving 2 for red and yellow.

Since red and yellow are the same number, there could be either 26 yellow, or 1 yellow. Since 1 isn't given as an option, it has to be C) 26.
