Scientific notation is a way of writing numbers in a form of a decimal multiplied by an exponent of 10.
For these, the exponent will be negative, since they're teeny tiny decimals, and we'll have to move the decimal point back to the right.
0.00000012 will become 1.2* 10^{-7}
This is because the decimal point is moved seven places to the right of where it originally was.
0.000005008 will become 50.08* 10^{-7}
Again, this is because the decimal point is moved seven places to the right of where it originally was.
So, your scientific notations are 1.2* 10^{-7} and 50.08* 10^{-7}

carlene bought 8 1/6 yards of ribbon to decorate a shirt. she only used 5 1/2 yards. how much ribbon does she have left
777dan777 [17]
To make things simple you can first find out what 8 1/16 is. 8 1/16 is approximately 8.0625. Then find what 5 1/2 is which is 5.5. Now all you have to do is subtract 5.5 from 8.0625 (8.0625-5.5) and that should be equal to 2.5625.

Simplify to create an equivalent expression. \qquad{-2(-5n+6)+5(2-7n)}−2(−5n+6)+5(2−7n)minus, 2, left parenthesis, minus, 5, n,
Usimov [2.4K]

Answer:

The equivalent expression is - 25n - 2 and it matches with option D.

Step-by-step explanation:

We have to simplify and create the equivalent expression for

{- 2(- 5n + 6) + 5(2 - 7n)}

Now, {- 2(- 5n + 6) + 5(2 - 7n)}

= 10n - 12 + 10 - 35n

= - 25n - 2

Therefore, the equivalent expression is - 25n - 2 and it matches with option D. (Answer)

Anthony Papantonis, owner of Nauset Construction, is bidding on two projects, A and B. The probability that he wins project A is
Fudgin [204]

Answer:

a) the probability of winning A and B is 0.4 (40%)

b) the probability of not winning either project is 0.1 (10%)

Step-by-step explanation:

if 2 events are independent then

P(A∩B)=P(A)*P(B)

where

P(A)= probability of winning project A

P(B)= probability of winning project B

P(A∩B)= probability of winning projects A and B

replacing values

P(A∩B)=P(A)*P(B) = 0.50 * 0.8 = 0.4

b) since

P(A∪B) = P(A) + P(B) - P(A∩B) = 0.50 + 0.8 - 0.4 = 0.9

where

P(A∪B) =  probability of winning A or B

therefore

probability of not winning either project = 1 - P(A∪B) = 1 - 0.9 = 0.1 (10%)
