The sampling approach that was used in the statement "Kane randomly sampled 250 nurses from urban areas and 250 from rural areas from a list of licensed nurses in Wisconsin to study their attitudes toward evidence-based practice" is Stratified random sampling.

Stratified random sampling is a method of sampling that is based on dividing the population into subgroups called strata. Stratified random sampling is a statistical sampling method that involves the division of the population into subgroups or strata, and a sample is then drawn from each stratum in proportion to the size of the stratum. It's a sampling method that ensures the representation of all population strata in the sample, making it more effective than simple random sampling.

Stratified random sampling is used when there are variations in the population that are likely to influence the outcome of the study. The stratified random sampling method is used to ensure that these differences are reflected in the sample. In this way, the results of the study are more representative of the entire population than they would be if a simple random sample were used.

Answer:

3n + 8 < 5n

n > 4

Step-by-step explanation:

Let

n = cost of viewing videos

Plan A: $3 per video viewed, plus a flat rate of $8 per month

Total cost for plan A = 3n + 8

Plan B: $5 per video viewed and no additional flat rate

Total cost for plan B = 5n

Plan A is less than the cost of viewing n videos using Plan B

The inequality

3n + 8 < 5n

8 < 5n - 3n

8 < 2n

8/2 < n

4 < n

n > 4

Answer: x= 6

Step-by-step explanation:

Since the shape is a parallelogram, the angles will either be equal to each other or add up to 180.  

You can see they do not look the same so they add up to equal 180

12x + 3 +105 = 180

12x + 108 = 180

12x = 72

x = 6

The correct option is A. 20,000, as there are a total of 20,000 phone numbers available for the small town.

We know that the phone numbers of a small town either begin with 373 or 377. We are required to find out the number of phone numbers that are available. To solve this question, we need to count the number of phone numbers that are available for each prefix.

The prefix 373 can have numbers ranging from 3730000 to 3739999. Similarly, the prefix 377 can have numbers ranging from 3770000 to 3779999.

Therefore, the total number of phone numbers that are available is the sum of the phone numbers available for each prefix.

Total number of phone numbers = Number of phone numbers available for prefix 373 + Number of phone numbers available for prefix 377

Total number of phone numbers = 10000 + 10000

Total number of phone numbers = 20000

Therefore, The correct option is A. 20,000, as there are a total of 20,000 phone numbers available for the small town.

Step-by-step explanation:

So on solving the provided question, we can say that inequality equation will be as follows r - 8 <= 7 r<=15 or r >= -15

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

The digit "1" appears 99,920 times when writing down all whole numbers from 1 to 99,999. To determine this, we can consider each place value separately.

1. Units place (1-9): The digit "1" appears once in each number from 1 to 9.

2. Tens place (10-99): In this range, the digit "1" appears in all numbers from 10 to 19 (10 times) and in the tens place of numbers 21, 31, ..., 91 (9 times). So the digit "1" appears 10 + 9 = 19 times in the tens place.

3. Hundreds place (100-999): The digit "1" appears in all numbers from 100 to 199 (100 times) in the hundreds place. Similarly, it appears in the hundreds place of numbers 201, 202, ..., 299 (100 times), and so on up to 901, 902, ..., 999 (100 times). So in the hundreds place, the digit "1" appears 100 * 9 = 900 times.

4. Thousands place (1000-9999): Similar to the previous cases, the digit "1" appears in the thousands place 1000 times in the range from 1000 to 1999. Also, it appears 1000 times in the thousands place of numbers 2000 to 2999, and so on up to 9000 to 9999. So in the thousands place, the digit "1" appears 1000 * 9 = 9000 times.

5. Ten thousands place (10,000-99,999): The digit "1" appears in the ten thousands place 90000 times since it occurs in all numbers from 10000 to 99999.

Adding up the counts from each place value:

1 + 19 + 900 + 9000 + 90000 = 99920

Therefore, the digit "1" appears 99,920 times when writing down all whole numbers from 1 to 99,999.

Therefore, The Coordinates of the THIRD VERTEX is:  ( 5, -3 )

        Calculate the midpoint of the given vertices:

        MidPoint = ( -5 + 5/2,  3 + 3/2 )

        MidPoint = ( 0, 3 )

        Distance = √( -5 -5 )^2 + ( 3 - 3 )^2

        Distance = √( -10 )^2  +  (0)^2

        Distance = √100

        Distance =  10

        Side Length =  10/√3

        Side Length = 10/1.7

        Side Length = 5.88

        Height = √3/2  *  Side Length

        Height  = 1.7/2  *  5.88

        Height  =  5

Since the origin lies inside the triangle, The Third Vertex will have a Positive  X-Coordinate and a Negative Y-Coordinate.

       ( x, y )

        x  =  -5 + x/2

Step-by-step explanation:

The correct option of the given statement "Janice's funds to triple if she has $5,000 invested in a bank that pays 9.4% annually" is 11.86 years.

To solve the problem, we can use the formula for the future value of a single sum.

FV = PV (1 + i)ⁿ

Where,

PV is the present value of the investment

"i" is the annual interest rate

n is the number of years

FV is the future value of the investment.

So, we can say that the future value (FV) of Janice's investment will be 3 times her present value (PV). Thus,

FV = 3 PV

    = 3 × 5,000

    = $15,000

Now, we can substitute the given values in the formula:

FV = PV (1 + i)ⁿ

15,000 = 5,000(1 + 0.094)ⁿ

Dividing both sides by 5,000, we get:

3 = (1 + 0.094)ⁿ

Taking the logarithm of both sides:

log 3 = log (1 + 0.094)ⁿ

log 3 = n log (1 + 0.094)

n = log 3 / log (1 + 0.094)

n = 11.86 years

Therefore, it will take approximately 11.86 years for Janice's funds to triple.

The probability that gas is not used for cooking at a household can be determined by considering the probabilities of shopping at Prime Foods and using gas for cooking.

Let's denote the event of using gas for cooking as G and the event of shopping at Prime Foods as P. We are given that the probability of G is 0.18, and the conditional probabilities are as follows: P(G) = 0.7 and P(~G) = 0.35.

To find the probability of gas not being used for cooking, we need to calculate P(~G|~P), which represents the probability of not using gas for cooking given that a person does not shop at Prime Foods.

Using conditional probability, we have P(~G|~P) = P(~G∩~P) / P(~P). Here, P(~G∩~P) represents the probability of both not using gas for cooking and not shopping at Prime Foods, and P(~P) represents the probability of not shopping at Prime Foods.

Since P(~G∩~P) + P(G∩~P) = P(~P), we can rewrite the equation as P(~G|~P) = [P(~G∩~P) + P(G∩~P)] / P(~P).

We are given P(G∩~P) = P(G) * P(~P|G) = 0.18 * (1 - 0.7) = 0.054.

Therefore, P(~G|~P) = [P(~G∩~P) + P(G∩~P)] / P(~P) = (0.054 + 0) / (1 - 0.35) = 0.054 / 0.65 ≈ 0.083.

So, the probability that gas is not used for cooking at the household, given that a person does not shop at Prime Foods, is approximately 0.083, which is option (a).

There are 658,008 ways to choose 5 non-Polluted lakes from the remaining 79 lakes.

To determine the number of ways to choose one polluted lake and five non-polluted lakes from a sample of 80 lakes, we can use the concept of combinations.

The total number of ways to choose a group of lakes from a larger set is given by the formula for combinations, which is denoted as "n choose r" and calculated as:

C(n, r) = n! / (r!(n-r)!)

Where n represents the total number of lakes and r represents the number of lakes to be chosen.

In this case, there are 80 lakes in the sample and we want to choose 1 polluted lake and 5 non-polluted lakes. Therefore, we have:

n = 80 (total number of lakes)

r = 1 (number of polluted lakes to be chosen)

Using the combination formula, we can calculate:

C(80, 1) = 80! / (1!(80-1)!)

         = 80! / (1! * 79!)

         = 80

So there are 80 ways to choose 1 polluted lake from the sample of 80 lakes.

Next, we want to choose 5 non-polluted lakes from the remaining 79 lakes (after choosing 1 polluted lake). Using the combination formula again:

C(79, 5) = 79! / (5!(79-5)!)

         = 79! / (5! * 74!)

         = 79 * 78 * 77 * 76 * 75 / (5 * 4 * 3 * 2 * 1)

         = 658,008

Therefore, there are 658,008 ways to choose 5 non-polluted lakes from the remaining 79 lakes.

To find the total number of ways to choose one polluted lake and five non-polluted lakes, we multiply the number of ways for each category:

Total number of ways = 80 * 658,008

                   = 52,640,640

Hence, there are 52,640,640 ways to choose one polluted lake and five non-polluted lakes from the given sample of 80 lakes.
