Find the first 3 iterates of the function f (x) = x - 4 when Xo = -11.
nikdorinn [45]
<h3>Answer:  Choice A</h3>

-11, -15, -19

================================================

Explanation:

Plug x = -11 into the function.

f(x) = x-4

f(-11) = -11-4

f(-11) = -15

The output -15 is now the input to set up the next iteration.

f(x) = x-4

f(-15) = -15-4

f(-15) = -19

The first three iterates are -11, -15, -19

explain why multiplying the numerator and the denominator of a fraction by the same number results in an equivalent fraction.​
alisha [4.7K]

Answer:

We also know that when you have the same numerator and denominator in a fraction, it always equals 1. For example: So as long as we multiply or divide both the top and the bottom of a fraction by the same number, it's just the same as multiplying or dividing by 1 and we won't change the value of the fraction.

A plant in the manufacturing sector is concerned about its sulfur dioxide emissions. The weekly sulfur dioxide emissions follow
egoroff_w [7]

Answer:

The correct option is b) 1.70

Step-by-step explanation:

Consider the provided information.

The weekly sulfur dioxide emissions follow a normal distribution with a mean of 1000 ppm (parts per million) and a standard deviation of 25.

Thus, μ=1000 and σ = 25

The CEO wants to know if the mean level of emissions is different from 1000.

Therefore the null and alternative hypothesis is:

H_0:\mu =1000 and H_a:\mu \neq1000

The sample size is n = 50 and \bar x=1006 ppm.

Now calculate the test statistic by using the formula: z=\frac{\bar x-\mu}{\frac{\sigma}{\sqrt{n}}}

Substitute the respective values in the above formula.

z=\frac{1006-1000}{\frac{25}{\sqrt{50}}}

z=\frac{6}{\frac{25}{\sqrt{50}}}=1.697\approx 1.70

Hence, the correct option is b) 1.70
