Why do most cells depend on other cells of the body for survival? Question 10 options: a) because body cells cannot perform all life-sustaining functions on their own b) because most cells of the body do not directly interact with the external environment and therefore need other cells to provide nutrients and remove wastes c) because cells do not contain fluid d) because all cells of the body are physically connected with one another

certain liquid X has a normal freezing point of -9.30 °C and a freezing point depression constant $K_f$ = 3.26 °C·kg·mol$^{-1}$. A solution is prepared by dissolving some benzamide ($C_7H_7NO$) in 300. g of X. This solution freezes at -13.2 °C. Calculate the mass of $C_7H_7NO$ that was dissolved. Round your answer to 2 significant digits. g
Which statement is the least related to Leonhard Euler (1707-1783)? He introduced the Greek letter \sum for the summation symbol. He introduced the notation $i$ for the imaginary number $\sqrt{-1}$. He established Hamiltonian mechanics. He gave the current definition of the constant $e$ (the Euler number), the base of the natural logarithm.

Part 1 Find the measure of the complement of an 18-degree angle.
Show your work! 1. Assume that $x$ and $y$ are both differentiable functions of $t$. Find $\frac{dx}{dt}$ when $x = 7$ and $\frac{dy}{dt} = -4$ for the equation $xy = 56$.
Analyze the Distribution Using your sample mean, sample standard deviation, and histogram to help, what is the approximate theoretical distribution of the data? X~( • How does the histogram help you arrive at the approximate distribution? Describe the Data Use the data you collected to complete the following statements. • The IQR goes from to IQR = (IQR = Q3 - Q1) • The 15th percentile is • The 85th percentile is • The median is • The empirical probability that a randomly chosen lap time is more than 130 seconds is • Explain the meaning of the 85th percentile of this data. Theoretical Distribution Using the theoretical distribution, complete the following statements. You should use a normal approximation based on your sample data. • The IQR goes from to IQR = • The 15th percentile is • The 85th percentile is • The median is • The probability that a randomly chosen lap time is more than 130 seconds is • Explain the meaning of the 85th percentile of this distribution. Discussion QuestionsDo the data from the section titled Collect the Data give a close approximation to the theoretical distribution in the section titled Analyze the Distribution ? In complete sentences and comparing the result in the sections titled Describe the Data and Theoretical Distribution, explain why or why not.
