Using the predicate symbols shown and appropriate quantifiers, write each English language statement as a predicate wff. (The domain is the whole world.) B(x) is “x is a ball.” R(x) is “x is round.” S(x) is “x is a soccer ball.” 1) some balls are round but soccer balls are not 2) if soccer balls are round, then all balls are round

he mean age of graduate students at a University is thought to be 31 years old. A random sample of 15 graduate students is taken. The sample mean age is 33 years and the sample standard deviation is three years. Does the sample data indicate that the population mean age is actually greater than 31 years old? Use a 1% level of significance. a.) What is α? State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or...

Imagine 2 identical capacitors with C = 1F having a charge Q = 1 C. Suppose you connect their terminals, positive to positive, negative to negative. Now you have an effective capacitance 2C carrying a charge 2Q, right? Work out the total energy of the two capacitors before and after the connection and speculate on the meaning of your result.

HW6#30 Use a normal approximation to find the probability of the indicated number of voters. In this​ case, assume that 125 eligible voters aged​ 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged​ 18-24, 22% of them voted. Probability that fewer than 32 voted. The probability that fewer than 32 of 125 eligible voters voted is ____?
