Approximately \( \lfloor 1439 \mid \) mosquitoes (Do not round until the final answer. Then round to the nearest whole number as needed.) (c) How long is it until there are 70,000 mosquitoes? About \( \square \) days (Do not round until the final answer. Then round to the nearest tenth as needed.)

Weights of golden retriever dogs are normally distributed. Samples of weights of golden retriever dogs, each of size \( n=15 \), are randomly collected and the sample means are found. Is it correct to conclude that the sample means cannot be treated as being from a normal distribution because the sample size is too small? Explain. Choose the correct answer below. A. Yes; the sample size must be over 30 for the sample means to be normally distributed. B. No; the original population is normally distributed, so the sample means will be normally distributed for any sample size. C. No; as long as more than 30 samples are collected, the sample means will be normally distributed. D. No; the samples are collected randomly, so the sample means will be normally distributed for any sample size.

\[ h(x)=(-5+x)(4+x) \] \( g(x)=-7-x \) (a) Find \( \left(\frac{h}{g}\right)(-4) \). (b) Find all values that are NOT in the domain of \( \frac{h}{g} \). If there is more than one value, separate them with commas. (a) \( \left(\frac{h}{g}\right)(-4)=\square \) (b) Value(s) that are NOT in the domain of \( \frac{h}{g}: \)

To convert \( \frac{\frac{3}{4}}{100} \) to a fraction with a whole number in the numerator and denominator, you can multiply by the form of 1 equal to equivalent is Suppose you chose to convert \( \frac{3}{4} \) \%to a fraction using the definition of percent. Complete each equation. \[ \begin{aligned} \frac{3}{4} \div & \frac{3}{400} \\ & =\frac{3}{400}\end{aligned} \]
