Ivan and Polina have each drawn a conclusion about multiplying negative fractions. Ivan: The product of an even number of negati

ddd [48]

Answer:

Both conclusions are correct

Step-by-step explanation:

Ivan: The product of an even number of negative fractions is always positive.

When even numbers of same negative fractions are multiplied together, the product is positive.

For instance: -1 × -1

Since the total numbers to be multiplied are even (two -1), the product becomes +1

Ivan's conclusion is correct.

Polina: The product of an odd number of negative fractions is always negative.

When odd numbers of same negative fractions are multiplied together, the product is negative.

For instance: -1 × -1 × -1 × -1 ×-1

Since the total numbers to be multiplied are odd (five -1), the product becomes -1

(-1 × -1) × (-1 × -1) ×-1

= +1 × +1 × -1

The multiplication of same sign gives positive value while the multiplication of two different signs gives a negative value

= +1 × -1

= -1

Polina's conclusion is correct

Both are correct.

Softa [21]

Answer:

A. Sailfish

Step-by-step explanation:

Looking at the problem, we need to focus on the speeds of the fishes. The sailfish has a max speed of 67.85 and the swordfish's is 60. Comparing the two values, 67.85 is greater, so Kesia should put the sailfish (A) on the cover of her report.

There are 12 members on the board of directors for the Newport General Hospital. If they must elect a chairperson, first vice ch

rosijanka [135]

Answer:

11880 different slates of candidates are possible.

Step-by-step explanation:

The order is important in this problem.

That is, John, Elisa, Laura and Rose means that John is the chairperson, Elisa the first vice chairperson, Laura the second vice chairperson and Rose the secretary. If we exchange John and Elisa, for example, it means that their roles also have changed.

So we use the permutations formula to solve this problem.

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

How many different slates of candidates are possible?

Four roles in a set of 12 members. So

$P_{(12,4)} = \frac{12!}{(12-4)!} = 11880$

11880 different slates of candidates are possible.

Draw an example of a composite figure that has a volume between 250 and 300 cubic units

sertanlavr [38]

The composite figure in the attached file

we know that

[the volume of the composite figure]=2*3*30+2*20*2-------> (180+80) units³
[the volume of the composite figure]=2*3*30+2*20*2-------> 260 units³

260 units³ < 300 units³
and
260 units³ > 250 units³
