Evaluate the expression for f = -6 and g = -1.<br> fg - f =
Arlecino [84]

Answer:

7

Step-by-step explanation:

Given the information from the question:

fg - f = f \times g - f

Next we can use the order of operations to find the value of the expression.

fg - f =  - 6 \times  - 1 - ( - 1) \\  =  6 - ( - 1) \\  = 6 + 1 \\  = 7

Substitute n=10, then

M(10) models Jayce's fee (in dollars) for his 10^{th} drive on a certain day.

This means Jayce's fee for his 10^{th} drive is equal to K dollars.

The mean percentange of a population of people eating out at least once a week is 57℅
Sidana [21]

Answer:

<u>The correct answer is B. between 56.45% and 57.55% </u>

Complete statement and question:

The mean percentage of a population of people eating out at least once a week is 57% with a standard deviation of 3.50%. Assume that a sample size of 40 people was surveyed from the population a significant number of times. In which interval will 68% of the sample means occur?

between 55.89% and 58.11%

between 56.45% and 57.55%

between 56.54% and 57.46%

between 56.07% and 57.93%

Source: brainly.com/question/1068489

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Mean percentage of a population of people eating out at least once a week  = 57%

Standard deviation = 3.5%

Sample size = 40

Confidence level = 68%

2. In which interval will 68% of the sample means occur?

For answering this question, we should find out the standard deviation of the sample, using this formula:

Standard deviation of the sample = Standard deviation of the population/√Sample size

Standard deviation of the sample = 3.5/√40

Standard deviation of the sample = 3.5/6.32

Standard deviation of the sample = 0.55

Let's recall that a confidence level of 68% means that 68% of the sample data would have a value between the mean - 1 time the standard deviation of the sample and the mean  + 1 time the standard deviation of the sample. Thus:

57 - 1 * 0.55 = 57 - 0.55 = 56.45

57 + 1  * 0.55 = 57 + 0.55 = 57.55

<u>The correct answer is B. between 56.45% and 57.55% </u>

You need to buy 8 packages of meat for a cookout. A package of hot dogs costs $2.19 and a package of hamburgers costs $5.89. You
Daniel [21]

Answer:

1.89x + 5.19y = 31.62.

Step-by-step explanation:

Let the pagke of hot dags be x

Let the pakage of hamburgers be y

Now they total up tp 8 packages.

xEliminate the cost

x+y=8

y=8-x

Cost of hotdogs = $1.89

Cost of hamburgers = $5.19

1.89x+5.19y=31.62

1.89x+5.19(8-x)=31.62

1.89x+41.52-5.19=31.62

-3.3x=--9.9

x=3

y=8-3

y=5
