Answer:

6 x 10^11

Step-by-step explanation:

6 x 10^11 = 60,000,000,000

0.2 x 10^5 = 020000, which doesnt make sense. in scientific notation, to only way for the number after the decimal when the whole number is 0 is if the exponent was negative. the correct answer is a, i took the test and got it right

program that generates two random numbers between one and 11. what is the probability that both values will be more than 7? numb

katovenus [111]

Answer:

1/9

Step-by-step explanation:

The numbers between 1 and 11 are:

2, 3, 4, 5, 6, 7, 8, 9, 10

There are 9 numbers.

Of the 9 numbers, 8, 9, and 10 are greater than 7, so there are 3 numbers greater than 7.

p(number greater than 7) = 1/3

p(>7) = 1/3

Each time a number is selected, the probability it is greater than 7 is 1/3.

For two numbers, you have two independent events, so the overall probability is the product of the individual probabilities.

p(>7 then >7) = p(>7) * p(>7) = 1/3 * 1/3 = 1/9

Chloe drives from her house to her grandma's house 64 miles away in an hour and 35 minutes. How fast was she driving on average?

Nataly [62]

Answer:

<h2>She was driving at 40.42 mph on average</h2>

Step-by-step explanation:

In this exercise, for us to find the speed that Chloe drives with we need to first convert the time she spent driving to hours completely since the time given is in hours and minute

Data

distance= 64 mile

time= 1hr 35min

to covert 1 hr 35 min to hours we have

= 1 + 35/60 (we are converting 35 min to hrs)

= 1+0.583

= 1.583

hence speed= 64/ 1.583

speed= 40.42 mph

She was driving at 40.42 mph on average

Chicxulub is a crater on the Yucatán Peninsula of Mexico. It was formed 6.5 × 107 years ago. Vredefort crater in South Africa wa

Rus_ich [418]

Answer: The oldest one is Vredfort Crater.

Step-by-step explanation:

The data is:

Chicxulub was formed 6.5x10^7 years ago.

Vredfort was formed 2x10^9 years ago.

Sudbury basin was formed 1.8x10^9 years ago.

Acraman crater was formed 5.8x10^8 years ago.

We want to find the oldest, so we need to find the larger number of the 4 we have.

For this, we need to see at the exponents, the larger the exponent the larger the number.

We have two with a 9 in the exponent:

Vredfort and Sudbury.

Now we look at the number, Vredfort has 2x10^9 and Sudbury has 1.8x10^9.

Both have the same exponent, but the scalar of Vredfort is larger (2 is greater than 1.8) so we have that Vredfort is older.
