answer:To test if 9939 is a prime number, we first consider that its square root is approximately 99.6. Thus, we only need to check divisibility by prime numbers less than or equal to 99. Since 9939 is odd, it is not divisible by 2. Next, we notice that the sum of its digits (9 + 9 + 3 + 9) equals 30, which is divisible by 3. This indicates that 9939 is also divisible by 3. Therefore, 9939 is not a prime number because it has a factor other than 1 and itself (it can be divided by 3). [ text{Answer: } 9939 text{ is not a prime number.} ]

answer:The probability that a standard normal variable, Z, is below 1.96 is 0.975. This can be calculated using the standard normal distribution table or a calculator. The probability that Z is below 1.96 is the area under the standard normal curve to the left of 1.96. This area can be found using the cumulative distribution function (CDF) of the standard normal distribution, which is given by: {eq}P(Z < z) = Φ(z) {/eq} where Φ(z) is the CDF of the standard normal distribution. Using a calculator or a table, we can find that Φ(1.96) = 0.975. Therefore, the probability that Z is below 1.96 is 0.975.
