Please help me the venn diagram is wrong too im confused on how to do this :(((

Kisachek [45]

Answer:

probability of chosing a student that has a cat and a dog is 9/25

Step-by-step explanation:

And yes the Venn diagram is wrong because you forgot to subtract 9 from 15 and 16

This makes it

[ 3 ( 6 ( 9 ) 7 ) ]

3 + 6 + 9 + 7 = 25

Madison is carrying a 11.3 liter jug of sports drink that weighs 7 kg.

stellarik [79]

Answer:

$\large\boxed{\large\boxed{constat\text{ }multiple=\frac{113liter}{70kg}}}$

Explanation:

The <em>constant multiple of liters in a jug to the weight in kilograms</em> is the ratio or <em>fraction</em> that represents the number of liters of the sports drink in a jug to the weight.

$constat\text{ }multiple=ratio=\frac{number\text{ }of\text{ }liters}{weight\text{ }in\text{ }kg}$

$constat\text{ }multiple=\frac{11.3liter}{7kg}$

Convert the fraction into an equivalent fraction with integer numbers:

$constat\text{ }multiple=\frac{11.3liter\times 10}{7kg\times 10}=\frac{113liter}{70kg}$

Since, the fraction cannot be reduced, that is the answer.

4. In a large community, 72% of the people are adults, 78% of the people have traveled outside the state, and 11% are adults who

natulia [17]

Answer:

a. The Venn diagram is explained in the attached word file.

0.61

b. Not independent

Step-by-step explanation:

a. The hypothetical 1000 table for given situation is

Adult(A) Not Adult (not A) Total

Travel outside (T) 610 170 780

Not Travel outside (not T) 110 110 220

Total 720 280 1000

P(Adult and travel outside)=P(A and T)=610/1000=0.61

b. Multiplication rule for independent events is

P(A and B)=P(A)*P(B)

P(A and T)=0.61

P(A)*P(T)=0.72*0.78=0.56

As P(A and T) is not equal to P(A)*P(T), so event "being an adult" and "travel outside" are not independent.

which functions have a range of all real numbers ? check all that apply. A. y=csc x B. y=sec x C. y=tan x D. y= cot x

Natalka [10]

None of these. All of these functions are defined as ratio of trigonometric functions.

Trigonometric functions have infinite zeroes, so when you put them in the denominator, they lead to infinitely many points of ill-definition.

Specifically, we have:

$\csc(x) = \dfrac{1}{\sin(x)}$

which is undefined at

$\sin(x)=0\iff x=k\pi, k\in\mathbb{Z}$

$\sec(x) = \dfrac{1}{\cos(x)}$

which is undefined at

$\cos(x)=0\iff x=\dfrac{\pi}{2}+k\pi, k\in\mathbb{Z}$

$\tan(x) = \dfrac{\sin(x)}{\cos(x)}$

which is undefined at

$\cos(x)=0\iff x=\dfrac{\pi}{2}+k\pi, k\in\mathbb{Z}$

$\cot(x) = \dfrac{\cos(x)}{\sin(x)}$

which is undefined at

$\sin(x)=0\iff x=k\pi, k\in\mathbb{Z}$
