I'd say it's 2km because 2m is about the same as the height of a grown man

There is about 323ft in a city block. 24*323=7752ft

7752ft to km is about 2.3km

So I would say it is 2km in the choices you gave

If you flip three fair coins, what is the probability that you'll get all three head?

Vlad [161]

Answer:

P (HHH) = 1/8

Step-by-step explanation:

We want the probability of HHH

P(HHH) = P (heads and Heads and heads)

When we have an and, we multiply the probability

P(heads 1st time) * p(heads 2nd time) * P (3rd time)

The probability of a heads is 1/2

1/2 * 1/2 * 1/2

P (HHH) = 1/8

Here is a pattern made from sticks: a)How many sticks would be in pattern 6? b) How many sticks would be in pattern number n?

Wittaler [7]

Answer:

a) 26

b) 4n+2

Step-by-step explanation:

From the given figure it is clear that,

Number of sticks in pattern 1 = 6

Number of sticks in pattern 2 = 10

Number of sticks in pattern 3 = 14

Now,

6, 10, 14, ...

It is an AP.

Here, first term = 6

Common difference = 10 - 6 = 4

nth term of an AP is

$a_n=a_1+(n-1)d$

where, $a_1$ is first term and d is common difference.

So, nth term of given AP is

$a_n=6+(n-1)4$

$a_n=6+4n-4$

$a_n=4n+2$

Now, substitute n=6 in the above equation to find the number of sticks in pattern 6.

$a_n=4(6)+2=24+2=26$

Therefore, the number of sticks in pattern 6 is 26.

Since $a_n=4n+2$ , therefore, the number of sticks in pattern n is 4n+2.

E is 3 more than D

gladu [14]

Part A:

We are given that E is 3 more than D. This means that to get the value of E, we will simply add 3 to the value of D

Therefore:

E = D + 3

Part B:

We are given that F is 5 less than D. This means that to get the value of F, we will simply subtract 5 from the value of D

Therefore:

F = D - 5

Part C:

To get the value of E-F, we will simply subtract the equation we obtained from part B from the equation we obtained from part A

Therefore:

E - F = (D+3) - (D-5)

E - F = D + 3 - D + 5

E - F = 8

Hope this helps :)

Determine the interval(s) on which the given function is decreasing?

eduard

Answer:

$(-\infty, -1) \cup (0, \infty)$

Step-by-step explanation:

The function is decreasing if, as x increases, the value of the function (y) gets smaller. This means as you read the graph from left-to-right, the function is decreasing if the graph is falling.

From -infinity to -1, the graph is falling, then the graph rises (f is increasing) until x =0, then the graph falls again from x = 0 to infinity.
