Q=1,Q'=0 as an active-high input s-r latch has a 1 on the s input and a 0 on the r input.

An SR latch (Set/Reset) is an asynchronous device that solely depends on the state of the S and R inputs and does not require any input from the control signals. The illustration demonstrates how two NOR gates with a cross-feedback loop may be used to build an SR latch. Set-reset, or S-R, latches are therefore the most basic type of bistable device. We can connect two NOR gates so that the output of one feeds back into the input of the other, and vice versa, to create an S-R latch, as shown below: The Q and not-Q outputs are supposed to be in opposing states.

The function in the graph is y = x² - 1 and the inverse of the function is y = √(x + 1) and the graph is attached

Examining the graph the vertex is v(h, k) = (0, -1)

Quadratic equation is of the form

y = a(x + h)² + k

using the vertex we write the equation as

y = a(x + 0)² - 1

using point (1, 0) a is calculated

0 = a(1 + 0)² - 1

a = 1

The equation of the graph is

y = a(x + 0)² - 1

y = x² - 1

The domain of the equation is all real numbers and the range is calculated from the inverse

x = √(y + 1)

y + 1 ≥ 0

y ≥ -1

Inverse function

y = x² - 1

x² = y + 1

x = ±√(y + 1)

Step-by-step explanation:

He has 25.65, sold 3.87. 25.65-3.87=21.78

(a) The probability that there will be exactly 3 eruptions in the next 200 years is 0.1404

(b) The probability the next eruption occurs between 25 and 50 years is 0.2488

Let X be the random variable denoting the volcanic eruptions as follows

Poisson distribution with parameters  λ.

the average of the eruption is  λ=2.5 per year.

Also for 200 eruptions the average of the eruptions is  λ=2.5 per year.

Also, for 200 eruptions, the average of the eruptions is  λ=5 per year.

The probability is:

P(X=3) = e⁻³(5)³/3!

= 0.0067×125/3×2×1

= 0.8422/6

= 0.1404

(b) Let X be the random variable denoting the volcanic eruptions as follows

Poisson distribution with parameters  λ and also let 2.5 eruptions in 100 years is same as waiting time of:

100/2.5

= 40 years per eruption

therefore, X ~ Exp(β=40)

the probability density function of X is:

f(x) = { 1/40 e⁻¹/⁴⁰ , x>0

          0 ,  otherwise}

And cumulative distribution function is:

P(X≤x) = 1 - e, x>0

the probability is:

P(25<X<50) = P(X<50)-P(X<25)

P(25<X<50) = e²⁵/⁴⁰ - e⁵⁰/⁴⁰

= e⁻°·°²⁵ - e⁻¹·²⁵

We REJECT the null hypothesis that these rats came from a population with a mean of 32 in favour of the alternative that they were selected in a way that the mean was different from 32 because our test statistic is bigger than this (in absolute value).

In the given question,

The population mean is 32g with a st. dev. of 4g.

We collect a sample of n=25 mice with a sample average of 30.4g.

We wish to test the hypothesis that these were drawn randomly from the population.

So our null hypothesis is

H0: mean = 32

Our alternative hypothesis is

HA: mean ≠ 32.

This is a two-sided test.

A sample mean should have the same mean as the population mean, and the sample st. dev. should be (pop st. dev./√n).

In this case, under the null hypothesis, the sample mean should be distributed with an average of 32 and a st. dev. of 4/√25 = 4/5 = 0.8.

To test this hypothesis, we need to calculate a test statistic and compare it to a critical value of the standard normal distribution.

Our test statistic is:

z = (Observed value - hypothesized value) / (st. dev. in sample mean)

z = (30.4-32)/0.8

z = -1.6/0.8

z = -2.

The critical value of the z-distribution with α/2 = 0.05/2 = 0.025 is 1.96.

A laboratory assistant was asked by a scientist to select 25 mice for an experiment. However, before performing the experiment the scientist decided to weigh the mice as an indicator of whether the assistant’s selection constituted a random sample or whether it was made with some unconscious bias (perhaps themice selected were the ones that were slowest in avoiding the assistant, which might indicate some inferiority about this group). If the sample mean of the 25 mice was 30.4, would this be significant evidence, at the 5 percent level of significance, against the hypothesis that the selection constituted a random sample?

The scale factor from the scale drawing to the actual triangle is; 1/3

The area of a triangle is calculated using the formula;

A = ¹/₂bh

Where;

A is area.

b is base.

h is height.

The two sides of the rectangle are 6 units and 3 units. Use the measurements in the formula. "u" is for units.

Thus;

A = ¹/₂(6)(3)  

A = 9 square units

The scale factor, represented by the variable "k", tells you how much a shape enlarged or reduced. If "k" is greater than 1, the shape enlarged. If "k" is greater than 0 and less than 1, the shape reduced

In this case, since the drawing is smaller than the actual triangle, the scale factor will be a fraction less than 1 and greater than 0.

The scale factor is used for side length. When it's used to find a side length, we use "k" multiplied by a side. Since the information we know is area, we find k² first, then isolate "k".

Divide the depicted triangle area by the actual area.

k² = 9 ÷ 81

99.7% of the Manufacturers claim that non-hybrid sedan cars have a lower mean miles-per-gallon (mpg) than hybrid ones.

On Subtracting 1 from your sample size, we get

100 – 1 = 99.

On Subtracting confidence level from 1, and then divide by two.

(1 – .997) / 2 = 0.0015

Now, df = 99 and α = 0.0015

from the table at df = 99 we got 2.262.

Divide your sample standard deviation by the square root of your sample size.

28 / √(100) = 2.8

Now, 2.262 × 2.8 = 6.33

What is z test?

If the data is distributed normally, a z test can be used to determine whether the means of two populations differ from one another. The z test statistic's value must be determined, together with the null hypothesis and alternative hypothesis setups, for this reason. On the z critical value, the decision criterion is based. The distribution graph is divided into acceptance and rejection zones during hypothesis testing by the z critical value. The null hypothesis can be rejected if the test statistic lies inside the rejection region; otherwise, it cannot.

What is Cost?

A mathematical formula known as the cost function is used to graph how production costs will change depending on the output level. To put it another way, it calculates the overall cost of production based on the quantity that is produced.

1) Let's compare chicken costs:

$3.09 * 3 = $9.27  (far store)

$3.29 * 3 = $9.87 (near store)

2) Now let's look at how much it costs to travel in your car:

    [tex]\frac{3.87}{23} = 0.169\ per \ mile[/tex]

           = $0.169 per mile.

3) Next, let's look how much it costs to travel to each store from the gas used. Multiply by 2 because you not only have to drive there, but also back home for the round trip:

2.3 miles * 2 = 4.6 miles

8.4 miles * 2 = 16.8 miles

4) Now to find the cost of gas for the respective trips:

$0.169 * 4.6 = $0.78

$0.169 * 16.8 = $2.84

5) We can just eyeball it from here that it's not worth it to travel, but for completion's sake, let's add the gas and chicken costs together:

The equation for the line of best fit to predict the salary for an employee with 6 years of experience is $58,587.

The letter m is frequently used to represent slope; the reason for this is unclear, although it is first used in English by O'Brien in 1844, who wrote the equation for a straight line as "y = mx + b," and by Todhunter in 1888, who wrote it as "y = mx + c."

Finding the ratio of "vertical change" to "horizontal change" between any two unique locations on a line yields the slope. When the ratio is stated as a quotient ("rise over run"), the result is the same for each

We have to take any two points in the given information and find the value of slope.

Let the two points are (0, 52000), (1, 53,150)

m=(53150-52000)/(1-0)

m=1150

Therefore, slope=1150

Now, the equation of the line is y=mx+b

52000=1150(0)+c

c=52000

Therefore, y=1150x+52000

For 6 years experience,

Take x=6 then,

Answer:

$58,587.

Step-by-step explanation:

Slope of y = 2x +80 is 2, y-intercept is 80, x-intercept is -40.

Slope is defined as how much the y-coordinate changes with respect to the x-coordinate. Slope remains constant anywhere on the line.

Given equation is y = 2x + 80, where y is total amount of spending by tourist in Florida, in billions of dollars and x represents the number of years since 2013.

Equation of a line in slope-intercept form is,

y = mx + c, where m is the slope of the line and c is the y-intercept.

Comparing the given equation with slope-intercept form, we get,

m = 2 and c = 80

Domain of the equation includes number of years from 2013 - 2017 and the range of the equation is the corresponding y values.

Since slope is positive, as x value increases, y value also increases.

x- intercept is the point where the line touches the x-axis. y-coordinate will be zero at that point.

0 = 2x + 80 ⇒ x = -40

For the equation y = 2x +80, slope = 2, y-intercept = 80, x-intercept = -40.

Domain is the set of all number of years from 2013 - 2017 and range is the corresponding amount spend by tourist in the years from 2013-2017. As x value increases, y value also increases.
