On Monday, Avi walked from his home to the school track and walked 4 laps around the track for a total of 3.5 miles. On Saturday

anyanavicka [17]

Answer:

3.5 = x + 4*y

4 = 2x + 2*y

Step-by-step explanation:

The total distance ran by Avi is the sum of the distance from his house to the track, and the total distance ran in the tracks (that is, the distance of one lap times the number of laps Avi ran).

If we call 'd' the total distance and 'k' the number of laps, we have the equation:

d = x + k*y

So with the data given, we can have the following system:

3.5 = x + 4*y

4 = 2x + 2*y

In the second equation, we have 2x because Avi ran from his home to the track, and in the end ran back home, so Avi ran the distance x two times.

Dan invests £18790 into his bank account. He receives 4.9% per year simple interest. How much will Dan have after 3 years? Give

garri49 [273]

Answer:

£21552.

Step-by-step explanation:

Given information:

Principal amount = £18790

Rate of simple interest =4.9% = 0.049 per year

Time = 3 years

Formula for simple interest:

$I=P\times r\times t$

where, P is principal, r is rate of interest and t is time in years.

$I=18790\times 0.049\times 3$

$I=2762.13$

Total amount after 3 year is

$A=P+I$

$A=18790+2762.13$

$A=21552.13$

$A\approx 21552$

Therefore, Dan have £21552 after 3 years.

We can solve this problem using the binomial distribution. A binomial distribution can be thought of as a success or failure outcome in an experiment or survey that is repeated multiple times.
Probability function of binomial distribution has the following form:
$P= \frac{n!}{k!(n-k)!} p^k(1-p)^{n-k}$
p represents the probability of each choice we want. k is the number of choices we want and n is the total number of choices.
In our case p=0.85, k=5 and n=6.
We can now calculate the answer:
$P= \frac{6!}{5!(6-5)!} 0.85^5(1-0.85)^{6-5}=0.39$
The probability is 39%.

Answer:

First = Poppy seed = 3x10^-4 grams = 0.0003 grams

Second = sesame seeds = 3.64x10^-6 grams = 0.00364 grams

third = 250 pumpkin seeds 21 grams = one seed 0.084 grams

Step-by-step explanation:

3.64x10^-6 kilograms *1000gr/Kilograms = 0.00364 grams

21/250 = 0.0084 grams one seeds
