Answer:each students receives 4 markers.

Step-by-step explanation: First, you have to find how many times 18 will go into 88. This is 4. 18·4=72. This means Mrs Wini gave out a total of 72 markers, with each student having 4. To check, you would do 88-72 which equals 16 and this matches up with what the remainder is in the word problem.

NISA [10]

The number of minutes remaining in the poultry's temperature zone is; 3 hours and 45 minutes

<h3>How to find the temperature zone?</h3>

We are told that On the counter is poultry that has been left at a temperature of 17.5 °C for 15 minutes.

Converting 17.5°C into Fahrenheit equals 63.5 °F.  This temperature in degrees Fahrenheit  is within the danger zone. Now, hot food can be held in the danger zone for 4 hours. Due to the fact that the food has been on the counter for 15 minutes already, it means that it can be held on the counter for another 3 hours and 45 minutes before it becomes unsafe.

A lawn service owner is testing new weed killers. He discovers that a particular weed killer is effective 89% of the time. Suppo
marissa [1.9K]

Answer:

The 90% confidence interval for p is (0.8236, 0.9564). The upper confidence limit for p is 0.9564.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

He discovers that a particular weed killer is effective 89% of the time. Suppose that this estimate was based on a random sample of 60 applications.

This means that \pi = 0.89, n = 60

90% confidence level

So \alpha = 0.1, z is the value of Z that has a pvalue of 1 - \frac{0.1}{2} = 0.95, so Z = 1.645.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.89 - 1.645\sqrt{\frac{0.89*0.11}{60}} = 0.8236

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.89 + 1.645\sqrt{\frac{0.89*0.11}{60}} = 0.9564

The 90% confidence interval for p is (0.8236, 0.9564). The upper confidence limit for p is 0.9564.
