rjkz [21]

Answer:

Step-by-step explanation:

Sin(35) =  opposite / hypotenuse

Sin(35) = 4 / hypotenuse                  Multiply both sides by the hypotenuse

hypotenuse * sin(35) = 4                  Divide by Sin(35)

hypotenuse = 4/Sin(35)

Sin(35) = 0.5736

hypotenuse = 4/0.5736

hypotenuse = 6.9737

Rounded answer 6.97

0=2x^2+3x+4<br><br>steps and answer pls​
serious [3.7K]

I will place 0 on the right side.

2x^2+3x+4 = 0

2 times 4 = 8.

What two numbers yield a product of 8 but when added produce a sum of 3, the middle term's coefficient?

There is no such number.

So, gotta use the quadratic formula.

I will set it up and let you do the math.

See attachment for the set up.

Suppose we have a binomial experiment with n= 40 trials and a probability of success p= 0.50.Is it appropriate to use a normal a
exis [7]

Answer:

We can approximate to normal.

The parameters of the approximate normal distribution are:

\mu=np=40*0.5=20\\\\ \sigma=\sqrt{npq} =\sqrt{40*0.5*0.5} =\sqrt{10} =3.16

P_B(r>23)\approx 0.314

It is not unusual to have 23 or more successes. The probabiltity of this event happening is 13.4%.

Step-by-step explanation:

To approximate the binomial distribution to a normal distribution, we can calculate n*p and n*q and if both are bigger than 5 we can do the approximation.

n*p=n*q=0.5*40=20

We can approximate to normal.

The parameters of the approximate normal distribution are:

\mu=np=40*0.5=20\\\\ \sigma=\sqrt{npq} =\sqrt{40*0.5*0.5} =\sqrt{10} =3.16

The continuity correction factor is used because the binomial is a discrete function and the normal a continous function.

The probability of 23 successes must be expressed in the normal distribution as:

P_B(r>23)=P_N(r>23+0.5)=P_N(r>23.5)\\\\z=(23.5-20)/3.16=1.1076\\\\P(r>23.5)=P(z>1.1076)=0.134\\\\P_B(r>23)\approx 0.314

It is not unusual to have 23 or more successes. The probabiltity of this event happening is 13.4%.
