The mean water temperature downstream from a power plant cooling tower discharge pipe should be no more than 95of. past experience has indicated that the standard deviation of temperature is 2of. the water temperature is measured on 9 randomly chosen days, and the average temperature is found to be 93of. round your answers to four decimal places (e. g. 98.7654). (a) is there evidence that the water temperature is acceptable at alpha equals 0.05? the water temperature significantly greater than 95of at alpha equals 0.05. (b) what is the p-value for this test? p-value = (c) what is the probability of accepting the null hypothesis at alpha equals 0.05 if the water has a true mean temperature of 99of?
you need to find 30% of 560.
1.) first, you must do 560 times 30%. turn 30% into a simplified fraction by putting 30 over 100. you can simplify 30/100 to 3/10.
2.) next, multiply 560 by 3/10, which equals 168.
in an equilateral triangle, each angle is the same
so each angle equals 60
subtract 3 from each side
5y +3-3 = 60-3
5y = 57
divide by 5
5y/5 = 57/5
y = 11.4
a linear equation is: an equation between two variables that gives a straight line when plotted on a graph.
i hope it at all
