How many times bigger is 3.45×10⁹ than 0.5×10⁴

GenaCL600 [577]

To solve 3.45 x 10⁹, you have to move the decimal point of 3.45 nine times to the right(---->). Once you do that, you get 3450000000. To solve 0.5 x 10⁴, you have to move the decimal point of 0.5 four times to the right. That equals 5,000. Now the final question is: How many times bigger is 3450000000 than 5,000. So, you divide 3450000000 by 5,000. That equals 690000.

A and B are two events.

svlad2 [7]

Answer:

A and B are not independent events because P(A|B)≠P(A)

is the correct answer.

Step-by-step explanation:

If A and B are independent then we must have

P(AB) = P(A) P(B) and also

P(A/B) = P(A)

We are given that

A and B are two events.

Let P(A)=0.5 , P(B)=0.25 , and P(A and B)=0.15 .

P(A/B) = P(AB)/P(B) = 0.15/0.5 = 0.3

i.e. P(A/B) is not equal P(A)

Similarly P(B/A) = P(AB)/P(A) = 0.15/0.25 = 0.6 not equal to P(B)

Hence A and B are not independent.

PLEASE HELP. I need DE AND EF!!!

AlekseyPX

Answer:

DE = about 41.843 (rounded to nearest thousandth)

EF= 34.276 (rounded)

Step-by-step explanation:

For DE, we know that the shorter side (the opposite side) is 24, while the angle across form it is 35°. We can use trigonometry to figure this out. SinФ equals the opposite side (in this case, 24) divided by the hypotenuse. Set sinФ equal to a ratio of the sides like this:

sin(35) = $\frac{24}{x}$

x represents the hypotenuse length, which we don't know; 35 is the angle measure. Next, isolate x so that the equation looks like this:

$\frac{24}{sin(35)}$ = x

You will need a calculator for the next part. (and make sure you're in degree mode!). evaluate sin(35) and divide 24 by that value. That is DE's length. DE = about 41.843 (rounded to nearest thousandth)

For EF, we can just use Pythagorean theorem now that we know the other sides' values.

EF^2 + 24^2 = DE^2

*a calculator might also be useful for this part.

EF= 34.276 (rounded)

ictor Malaba has a net income of $1,240 per month. If he spends $150 on food, $244 on a car payment, $300 on rent, and $50 on sa

maksim [4K]

He spends 150+244+300+50=744 on the listen items so he he has 496 left to spend.

$\frac{496}{1240}=\frac{248*2}{248*5}=\frac{2}{5}$

so 40% of his net income.
