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
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.
33. "Of" in math problems means multiply therefore 55% or 0.55 multiplied by 60 is 33
7/8 / 2/7 =
7/8 * 7/2 = 49/16 = 3 1/16

Answer:
We can approximate to normal.
The parameters of the approximate normal distribution are:


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.

We can approximate to normal.
The parameters of the approximate normal distribution are:

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:

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