Answer:
The distance from Simon's house to the beach is 137.5 miles
Step-by-step explanation:
we know that
The speed is equal to the ratio of the distance and the time
Let
s ----> the speed in mph
x ----> the distance in miles
y ---> the time in hours

we have


substitute in the formula and solve for x


To solve the question we shall use the formula for the range given by:
Horizontal range, R=[v²sin 2θ]/g
plugging in our values we get:
500=[160²×sin 2θ]/10
5000=160²×sin 2θ
0.1953=sin 2θ
thus:
arcsin 0.1953=2θ
11.263=2θ
hence:
θ=5.6315°~5.63
The standard deviation for the number of seeds germinating in each batch is 1.3
<u>Solution:</u>
<em><u>In binomial distribution, standard deviation is given as:</u></em>

Where "n" is the number of observations
"p" is probability of getting success
We are given that:
Total batches of seed = 8
Probability that a radish seed will germinate is 0.7
Here success is getting radish seed germinated
<em><u>Then, the standard deviation for the number of seeds germinating in each batch.</u></em>
Plugging in values in formula, we get

Therefore the standard deviation for the number of seeds germinating in each batch is 1.3
