Answer 1
Answer:

The given triangle is a righttriangle.

Option E is the correct answer.

What is a triangle?

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

The sum of the angles must be 180.

So,

45 + 45  + 90 = 180

This is a condition for the right triangle.

Thus,

The given triangle is a righttriangle.

Find the mean of the binomial random variable. Round to two decimal places when necessary. According to a college survey, 22% of all students work full time. Find the mean for the random variable X, the number of students who work full time in samples of size 16. Group of answer choices 2.75 4 3.52 0.22

Answers

Answer:

3.52

Step-by-step explanation:

Calculation to Find the mean for the random variable X

Using this formula

Mean(μ) =(n*p)

Where,

n=16

p=22% or 0.22

Let plug in the formula

Mean(μ)=16×0.22

Mean(μ)=3.52

Therefore the mean for the random variable X will be 3.52

How to solve this type of question

Answers

In general, you solve questions of cancavity by looking at the second derivative. It will be negative where the function is concave downward. (It will be positive for concave upward, and zero at points of inflection.)

I find it convenient to get guidance from a graphing calculator.

f(x) is concave downard on the interval (-∞, 2).

_____
The derivative is
.. f'(x) = e^-x -x*e^-x
The second derivative is
.. f''(x) = -e^-x -(e^-x -x*e^-x)
.. = (x -2)*e^-x
This will be negative for x < 2.

Zinfandel is a popular red wine varietal produced almost exclusively in California. It is rather controversial among wine connoisseurs because its alcohol content varies quite substantially from one producer to another. In May 2013, the author went to a certain website, randomly selected 10 zinfandels from among the 325 available, and obtained the following values of alcohol content (%). 14.9 14.5 16.2 14.3 15.9
13.7 16.2 14.6 13.9 15.1
A. Calculate the interpret several measures of center.

B) 0.829

Step-by-step explanation:

Given the data :

% Alcohol content of 10 zindafel wine

14.9 14.5 16.2 14.3 15.9

13.7 16.2 14.6 13.9 15.1

Sorted value : 13.7, 13.9, 14.3, 14.5, 14.6, 14.9, 15.1, 15.9, 16.2, 16.2

Range = maximum - minimum

Range = 16.1 - 13.7

n = number of samples = 10

Median = 1/4(n + 1)th term

Median = 1/4(10+1)th term = 11/4 = 2.75 th term

(14.3 + 14.5) / 2 = 28.8 /2 = 14.40

Mode = 16. 2 ( most occurring observation)

Mean(m) = (13.7 + 13.9 + 14.3 + 14.5 + 14.6 + 14.9 + 15.1 + 15.9 + 16.2 + 16.2) / 10

= 149.3 / 10

= 14.93

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.5 cm. Use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (Round your answers to four decimal places.) My Notes Ask Your Teacher (a) the volume of the cube maximum possible error relative error percentage error cm
(b) the surface area of the cube maximum possible error relative error percentage error cm Need Help? ReadTalk to Tuter

Answers

Answer with Step-by-step explanation:

We are given that

Side of cube, x=30 cm

Error in measurement of edge,\delta x=0.5 cm

(a)

Volume of cube, V=x^3

Using differential

dV=3x^2dx

Substitute the values

dV=3(30)^2(0.5)

dV=1350 cm^3

Hence,  the maximum possible error in computing the volume of the cube

=1350 cm^3

Volume of cube, V=(30)^3=27000 cm^3

Relative error=(dV)/(V)=(1350)/(2700)

Relative error=0.05

Percentage  error=0.05* 100=5%

Hence, relative error in computing the volume of the cube=0.05  and

percentage error in computing the volume of the cube=5%

(b)

Surface area of cube,A=6x^2

dA=12xdx

dA=12(30)(0.5)

dA=180cm^2

The maximum possible error in computing the volume of the cube=180cm^2

A=6(30)^2=5400cm^2

Relative error=(dA)/(A)=(180)/(5400)

Relative error  in computing the volume of the cube=0.033

The percentage error in computing the volume of the cube=0.033* 100=3.3%
