If a polynomial has more than one variable, then the degree of that monomial is the sum of the exponents of those variables. In this polynomial, 24xyz, the degree is 3 because the sum of degrees of x, y and z is 1 + 1 + 1 = 3.

Answer:
There are 9 pizza rolls and 12 mini hotdogs in the meal.
Step-by-step explanation:
We are given the following in the question.
Let x be the number of pizza rolls sold and y be the number of mini hotdogs in the combination meal.
Total number of items in combination meal = 21
Thus, we can write the equation:
Calorie in a pizza roll = 60
Calorie in a mini hotdog = 70
Total calories = 1380
Thus, we can write the equation:
Solving the two equations, we get,
Thus, there are 9 pizza rolls and 12 mini hotdogs in the meal.
Answer:
Correct option is (A).
Step-by-step explanation:
Let <em>p</em> = proportion of water samples that exceeded the desired pH level.
A sample of size <em>n</em> = 648 is selected. Of these samples <em>X</em> = 62 exceeded the desired pH levels.
The confidence interval for the population proportion is given by:
The MOE or margin of error is estimated difference between the true population parameter value and the sample statistic value.
The information provided is:
MOE = 0.02
Compute the 90% confidence interval for the proportion of water samples that exceeds the desired pH level as follows:
Thus, the 90% confidence interval for the proportion of water samples that exceeds the desired pH level is (8%, 12%).
This confidence interval implies that there is a 90% confidence that the river water exceeds the desired pH level between 8% and 12% of the time studied.
The correct option is (A).
