Answer:

1) 8.5

2) 60

3) 69.3

4) 6.8

5) 3.6

6) 10.5

Step-by-step explanation:

Take out the decimal of the estimated factors and multiply. Count how far to left the decimal is in the factors. In the product, put the decimal as many to the left as it was in the factors. (ex. 6.93 x 42, 6.93 rounds to 6.9, 42 rounds to 40, 69 x 40 = 2,760, move the decimal over one for correct place value, 6.9 x 40 = 276.0 <em>or </em>276)

What is the square root of 7 + x if x is 100 - 26

finlep [7]

If x is 100-26
x=74
So
The square root of 7+ x is
$\sqrt{7 + 74} \\ = \sqrt{81} \\ = 9$

In a sample of 50,001st born babies eight were found to have a certain syndrome. Find the empirical probability that a family's

jenyasd209 [6]

Answer:

Empirical Probability that a family's first child will be born with this syndrome is 0.0002.

Step-by-step explanation:

Empirical Probability of an event E is defined

$\textrm{P(E)} = \frac{\textrm{Number of times the event actually happens}}{\textrm{ Total number of times the experiment performed }}$

Let E: Event that the child born has a certain syndrome.

Now here, total number of times experiments performed = 50,000

The number of favorable outcome = 1

$\implies P(E) = \frac{1}{50,00} = 0.0002$

Hence, here the Empirical Probability that a family's first child will be born with this syndrome is 0.0002.

I’m really trying to figure this out, but cant. Can someone help me

Sedbober [7]

there are 60 seconds in 1 minute.

there are 60 minutes in 1 hour.

so in 1 hr there are 60 * 60 seconds, 60 minutes 60 times :).

so 1 hr has 3600 seconds then.

how many seconds in 17 hours? well just 17 * 3600, their product.

we know the photon can do 3x10⁸ meters in one second, namely 300000000 m/s.

so, how many meters did it travel in 17 hours?

well, we know 17 hours is (17*3600) seconds

so, we can say, how many seconds did the photon travel in (17*3600) seconds? we know it can do 3x10⁸ in 1 second alone.

so the distance travelled is just their product, (17*3600) * 300000000.

so is really just 18360000000000 meters, or in scientific notation, there are 10 zeros and then we move the dot over 3 more slots in front of the "1", 1.836 x 10¹³.
