Step-by-step explanation:

The mean and standard deviation are:

μ = p

σ = √(pq/n)

Given p = 0.12, q = 0.88, and n = 200:

μ = 0.12

σ = √(0.12 × 0.88 / 200)

σ = 0.023

Since the sample is large, it can be approximated with a normal distribution. Find the z-score:

z = (x − μ) / σ

z = (0.14 − 0.12) / 0.023

z = 0.87

Use a calculator or table to find the probability:

P(Z > 0.87) = 1 − 0.8078

P(Z > 0.87) = 0.1922

morpeh [17]

Answer: (1,4)

Step-by-step explanation:

Given

Equation of line is $2y-3x=5$

(-1,1) is the solution of the equation

Take x=1 and substitute it in the above equation

$\Rightarrow 2y-3(1)=5\\\Rightarrow 2y=5+3\\\Rightarrow y=4$

So, another pair of the solution is (1,4)

What equation best models this data? (Use y to represent the population in millions, and t to represent the year, assuming that

lapo4ka [179]

Answer:

y = 2.31x + 309.35

Step-by-step explanation:

Whenever you are checking for a best fitting equation you want to check if it has a constant slope. If it does then the relation is linear and super easy.

So, since the t values are increasing by the same amount you want to see if the y values are too. And they are, each population entry is increasing by 2.31, this is the slope.

Also, keep in mind you can caluclate slope with the equation $\frac{y_2-y_1}{x_2-x_1}$ here x is replaced by t though.

Now, since we know it's linear and we know the slope we can find the equation with the formula y - y1 = m(x - x1) where again, x is replaced by t and m is the slope 2.31

I am just going to use the first point. so x1 = t1 = 0

y - 309.35 = 2.31(x-0)

y = 2.31x + 309.35

Let me know if there was something you didn't understand.
