Its a line plot, for every number that is listed put a mark above the number on the number line. So if there was 3 6's, on the number line above the 6, put 3 marks like dots or x's to represent the amount of 6.
Hope you understand.

1.what is the volume of the small cone in terms of pi

svp [43]

Step-by-step explanation:

Step 1: Find the radius of the big cone

$\frac{radius_1}{height_1} = \frac{radius_2}{height_2}$

$\frac{2}{5}=\frac{x}{10}$

$2(10)=5(x)$

$20/ 5=5x / 5$

$4=x$

Step 2: Find the volume of the small cone

$V = \frac{\pi*r^2*h} {3}$

$V = \frac{\pi * 2^2 * 5}{3}$

$V = \frac{20\pi}{3}\ units^3$ ← Volume of Small Cone

Step 3: Find the volume of the large cone

$V = \frac{\pi*r^2*h} {3}$

$V=\frac{\pi*4^2*10}{3}$

$V = \frac{160\pi}{3}\ units^3$ ← Volume of Large Cone

The level of nitrogen oxides (NOX) in the exhaust after 50,000 miles or fewer of driving of cars of a particular model varies No

Greeley [361]

Answer:

For a level of 0.0174 or more of nitrogen oxide, the probability of fleet is 0.01.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 0.02 g/mi

Standard Deviation, σ = 0.01 g/mi

Sample size, n = 81

We are given that the distribution of level of nitrogen oxides is a bell shaped distribution that is a normal distribution.

Standard error due to sampling:

$=\dfrac{\sigma}{\sqrt{n}} = \dfrac{0.01}{\sqrt{81}} = 0.0011$

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.01

P(X > x)

$P( X > x) = P( z > \displaystyle\frac{x - 0.02}{0.0011})=0.01$

$= 1 -P( z \leq \displaystyle\frac{x - 0.02}{0.0011})=0.01$

$=P( z \leq \displaystyle\frac{x - 0.02}{0.0011})=0.99$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 0.02}{0.0011} = -2.326\\\\x = 0.0174$

For a level of 0.0174 or more of nitrogen oxide, the probability of fleet is 0.01.

Consider the function f(x) = (x − 3)2(x + 2)2(x − 1). The zero has a multiplicity of 1. The zero −2 has a multiplicity of?

Gnom [1K]

The -2 has a multiplicity of 2

Since the order of (x+2) is squared, i.e. power is 2
