let t be the number of tulips. which algebraic sentence would you figure out how many tulips latonya bought?
a. t + 2(t + 3) = 45
b. t + 2(t – 3) = 45
c. 2t (t + 3) = 45
d. -3t + 2t = 45

The contents of 3838 cans of coke have a mean of x¯¯¯=12.15x¯=12.15. assume the contents of cans of coke have a normal distribution with standard deviation of σ=0.12.σ=0.12. find the value of the test statistic zz for the claim that the population mean is μ=12.μ=12.

We just started the introduction into circles and i have no idea how to do this.

Now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
