Estimate 71,903 - 25,368 by first rounding each number to the nearest thousand.

1 answer:

6 0

Rule of thumb in basic rounding is 5 above round up, below five don’t round up.

To round to the nearest thousand, you look at the hundred place. What is the number nearest to?

71,903 Is rounded up to 72,000
^

25,368 is rounded to 25,000
^

72,000 - 25,000 = 47,000

A group of pirates captures Kevin, Lisa, Matt and Neal, and forces them to play a game. They each roll a fair 6-sided-die once.

elena-s [515]

Answer: Option B, 16/81

Step-by-step explanation:

So we have 4 prisoners, they will roll a fair six side die and the product of the four rolls must NOT be a multiple of 3.

We know that every integer number can be "decomposed" into a product of prime numbers.

Then a number N, that is divisible by 3, can be written as:

N = 3*k

Where k is another integer.

Here we will have a product of 4 numbers, each of them are in between 1 and 6.

Now, if only one of the prisoners rolls a 3, then the product of the rolls will always be a multiple of 3. And if one of the rolls is 6 the same will happen, because 6 = 3.2

Then the probability of surviving is when in none of the four rolls we have a 3 or a 6.

Then we must have a 1, 2, 4 or 5.

The probability of 4 outcomes out of 6, is:

P = 4/6.

But we have 4 rolls, so we have that probability four times, and the joint probability will be equal to the product of the probabiliities for each roll, then the probability of surviving is:

P = (4/6)^4 = (2/3)^4 = 16/81

AREAS AND VOLUMES OF SIMILAR SOLIDS URGENT?

Novosadov [1.4K]

Two similar prisms have proportional dimensions. Find the ratio between lengths of these prisms:

$k=\dfrac{7}{5}$ .

The ratio between volumes of similar prisms is

$\dfrac{V_{large}}{V_{small}}=k^3$ .

If volume of small prism is 50 cub. m, then

$\dfrac{V_{large}}{50}=(\dfrac{7}{5} )^3=\dfrac{343}{125},\\V_{large}=\dfrac{343\cdot 50}{125} =137.2$ cub. m.

Answer: 137.2 cub. m.

Find sin theta if cot theta =-4 and cos theta < 0

asambeis [7]

Imagine the unit circle. The cot(theta) is a line from (0,1) to (-4,1). Imagine it is part of a triangle with the origin (draw it!).

Then the hypotenuse length is √(1+4²) = √17.

The sine rule says that sin(90)/√17 must equal sin(theta)/4, and sin(90)=1, so

$sin(\theta) = \frac4{\sqrt{17}}$
