Dahasolnce [82]

Answer:

the values of the population and sample proportions is 0.64 and 0.6 respectively

Step-by-step explanation:

The computation of the values of the sample proportions and the population is shown below:

Given that

Let us assume the population be P

N= 1000

X = subjects possess specific characteristic = 640

So,

P = X ÷ N

= 640 ÷ 1000

= 0.64

And, the sample proportion is

n = 40

x = subjects possess specific characteristic = 24

p =X ÷ N

= 24 ÷ 40

= 0.6

hence, the values of the population and sample proportions is 0.64 and 0.6 respectively

The position function for a free-falling object is s(t) = -16t^2 + vt +5. A ball is thrown upward from the top of a 400-foot bui

mixer [17]

Answer:

6.21 seconds

Step-by-step explanation:

The position function of a free-falling object is,

$s(t) = -16t^2+v_0t+s_0$

Where,

$s_0$ = initial height of the object,

$v_0$ = initial velocity of the object,

Here,

$s_0=400\text{ feet}$

$v_0=35\text{ feet per sec}$

Hence, the height of the ball after t seconds,

$s(t)=-16t^2+35t+400$

When s(t) = 0,

$\implies -16t^2+35t+400=0$

$t=\frac{-35\pm \sqrt{35^2-4\times -16\times 400}}{2\times -16}$

$t=\frac{-35\pm \sqrt{1225+25600}}{-32}$

$\implies t\approx -4.02\text{ or }t\approx 6.21$

∵ Time cannot be negative,

Hence, after 6.21 seconds the ball will reach the ground.

High school gives too much homework. Studies have shown that teenagers get less sleep because they are worried about homework. On the weekdays teenagers need about eight or more hours of sleep, but because of homework they cannot. Most of the time the homework we get we won't be using; unless we go into that business. There are times homework is a waste since most people don't do it. They use a lame excuse. Homework that we get we don't remember for a test. So why get it? How come we get too much homework? We don't sleep, don't do it, forget it at home, or don't need it when we are older. There are classes let's take math for instance, we get too much a week. There might be questions we have that our parents don't know. Instead of going outside we have to do homework. High school can be tough on us high schoolers. There's a lot expected of us. Especially homework. It will give us stress and tired through the day and night. Some high schoolers even drink caffeine to keep them up to do homework. That isn't healthy for us.

Hope this helps somewhat ^^
