if one check in 10,000 is forged, 5% of all checks are postdated, and 80% of forged checks are postdated, find the probability that a postdated check is forged. (round your answer to five decimal places.)

The information is provided below using a random sampling from a healthy population. a 90% confidence interval for . 114 is the lower bound of the confidence interval.

To find the lower bound of the 90% confidence interval, we need to calculate the 5th percentile of the data. To do this, use the formula that goes like this:

5th percentile = 114 + (0.90 * (512 - 114))

= 114 + (0.90 * 398)

= 114 + 358.2

= 472.2

Therefore, the lower bound of the 90% confidence interval is 472 (rounded to the nearest integer).

The slope percentage of the given ratio i.e. 1:12 is 83.33%.

You can determine the slope percentage by dividing the elevation change by the horizontal distance covered (sometimes called "the rise divided by the run") and multiplying the result by 100. The "run" assumes a flat surface - it doesn't account for elevation change when factoring in the actual distance traveled.

Example: let’s assume a mountaineer climbs 1,000 feet in altitude (the rise) and the horizontal distance measured on the map is 2,000 feet (the run).

thus, 1,000/2,000 = 0.5

Multiply 0.5 by 100 to derive the percent of the slope, which is 50%.

Hence, the slope percentage of 1:12 is = (1/12) x 100

                                                                  = 8.33 x 100

                                                                = 83.33 %.

Yes a sound argument has true conclusion this statement is true.

1. A valid argument must have a true conclusion.

This statement(1) is false. A valid argument must have a true conclusion only if all of the premises are true.  So it is possible for a valid argument to have a false conclusion as long as at least one premise is false.

2.A sound argument must have a true conclusion.

This Statement(2) is true.

If an argument is sound, then it is valid and has all true premises.  Since it is valid, the argument is such that if all the premises are true, then the conclusion must be true.  A sound argument really does have all true premises so it does actually follow that its conclusion must be true.

3. If a valid argument has a false conclusion, then at least one premise must be false.

The slope of the line that passes through the points (-5, 6) and (-9, -6) is 3

What is slope ?

A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).

Let the given points as shown:

(x1,y1)= (-5, 6) and (x2,y2)= (-9, -6)

Slope = m = (y2-y1) /( x2-x1)

                 = (-6-6) /(-9-(-5))

                 = -12/-4

Answer:

84%

Step-by-step explanation:

To find the mean, you use a formula.

You add up all the numbers, then divide that by how many numbers you have:

80 + 92 + 80 + 84

336 / 4 = 84

thus 84 is the answer

Note that this line is in form y = mx + b, where b is the y intercept and m is the slope.

Y intercept is the value of y at x = 0

The function starts at y = 6

Slope is 1/4, meaning that for every 4 x the line travels, it goes up 1.

Answer:

If a shirt is on sale for 25% off and the original price was $120, then the sale price is $90. This is because 25% of $120 is $30, and when we subtract this amount from the original price, we get $120 - $30 = $90.

In general, if an item is on sale for x% off and the original price was y dollars, then the sale price is y - (x/100) * y dollars. For example, if the discount is 25% and the original price is $120, then the sale price would be $120 - (25/100) * $120 = $90.

Step-by-step explanation:

Answer:

The sale price is $90

Step-by-step explanation:

Now,

(120 × 25) ÷ 100 = $30

Here, we get 25% of $120 is $30

So,

$120 - $30 = $90

Thus, The sale price is $90

Medical institution 64 grams of bismuth-214 must be prepared.

A medical institution is a facility in which medical care is provided. It can be a hospital, clinic, nursing home, or other type of health care facility. Medical institutions provide a wide range of services including diagnosis, treatment, and preventive care. In addition to providing direct patient care, they also provide educational opportunities, research, and administrative services. Medical institutions are staffed by a variety of healthcare professionals such as doctors, nurses, allied health professionals, and administrative staff. They are responsible for providing quality care to their patients and ensuring the safety and wellbeing of their staff and visitors.

Given: 2 hours = 20 minutes

If each half life is 20 minutes, and 2 hours (120 minutes) go by,

Given that line CE  bisects line FG.

DG= DE,

The length of segment CE is forty two feet.

CE=42 feet.

The length of segment CD is Twenty nine feet.

CD=29 feet.

We need to find the length of FG.

Firstly let us find the length of DE.

CE-CD=DE

42-29=13 feet.

As DG=DE then the length of DG is 13 feet.

DG=DF=13

FG=DG+DF
