Choose an acre of land in Canada at random. The probability is 0.45 that it is forest and is 0.03 that it is pasture. What is the probability that the chosen acre is not forested?

a. 0.03
b. 0.45
c. 0.55

Answers

Answer 1

Answer:

c. 0.55

Step-by-step explanation:

A chosen acre of land is forested and not forested are complimentary event , so let :

F = Chosen land is forested

F = Chosen land is not forested

....and we know  F+F = S

where S is sample space and we know probability ocer whole sample space is 1 , that is P(S)=1 , and we know F and F are independent so

P(F+F) = P(S)

P(F) + P(F)=1

We have given that probability of forest land in randomly chosen an acre land in Canada have probability 0.45 so P(F)=0.45 so ,

0.45 + P(F) = 1

P(F) = 1 - 0.45

P(F) = 0.55

Hence, the probability that the chosen acre is not forested is 0.55

Is 56 × 19/20 greater than or less than 56?

Answers

Answer:

Less

Step-by-step explanation:

56 is multiplied by 19/20 which is obviously less than one

Answer:

Step-by-step explanation:

56/60 = 0.9333

19/20 = 0.95

Now that these fractions have been converted to decimal format, we can compare the numbers to get our answer. 0.9333 is NOT greater than 0.95 which also means that 56/60 is NOT greater than 19/20.

Hopefully this tutorial has helped you to understand how to compare fractions and you can use your new found skills to compare whether one fraction is greater than another or not!

What is the slope of the linear function in decimal form?

Answers

Answer:

Slope = 0.6

Step-by-step explanation:

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

By applying this rule in the table attached,

Let the two points are (35, 94) and (45, 88) through which the graph of a linear function is passing.

Slope of the linear graph = [tex]\frac{94-88}{45-35}[/tex]

                                          = [tex]\frac{6}{10}[/tex]

                                          = 0.6

Therefore, slope of the linear function is 0.6

A kitchen sink faucet streams 0.5 gallon of water in 10 seconds. A bathroom sink faucet streams 0.75 gallon of water in 18 seconds. Which faucet will fill a 3-gallon container faster?

Answers

Answer:

A kitchen sink faucet

Step-by-step explanation:

0.5 gallon of water × 6 = 3 gallons

10 second × 6 = 60 seconds = 1 minute

 

0.75 gallon of water × 4 = 3 gallons

18 seconds × 4 = 72 seconds = 1 minute 12 seconds

1 minute is faster than 1 minute and 12 seconds by 12 seconds

so a kitchen sink faucet

Step-by-step explanation:

Easiest way to do this is find the area of the incomplete square, and then cut that in half for the triangle.

so it is 4 cm wide

and 8 cm tall

length x width = area

8 x 4 = 32

32/2 = 16

So your answer should be 16 cm

As per cubic equation, there will be one real solution of the given equation.

What is a cubic equation?

"A cubic equation is an algebraic equation of degree three and is of the form ax³ + bx² + cx + d = 0. x is a variable.

Here a, b and c are the coefficients and d is the constant"

Given cubic equation is:

x³ + 6x² + 12x + 8 = 0

⇒ x²(x + 2) +4x(x + 2) + 4(x + 2) = 0

⇒ (x + 2)(x² + 4x + 4) = 0

⇒ (x + 2)(x + 2)²  = 0

⇒ (x + 2)³ = 0

⇒ x = -2

There will be one real solution of the given equation.

Answers

Answer:

[tex]0, \dfrac{\pi}{6}, \dfrac{5\pi}{6}, \pi[/tex]

Step-by-step explanation:

Given the equation:

[tex]sin(x)-2sin(x) tan(x)=0[/tex]

To find:

The solutions of given equation in the range [0, 2[tex]\pi[/tex]) i.e. 0 can be in the answer but [tex]2\pi[/tex] can not be there in the answer.

Solution:

Taking [tex]tan(x)[/tex] common, we get:

[tex]tan(x) (1-2sin(x))=0[/tex]

The solutions can be given as:

[tex]tan(x) = 0[/tex] OR [tex]1-2sin(x) = 0[/tex]

Let us solve both the equations one by one:

First equation:

[tex]tan(x) = 0\\ \Rightarrow x=0, \pi[/tex]

Second equation:

[tex]1-2sin(x) = 0\\\Rightarrow 2sinx=1\\\Rightarrow sinx=\dfrac{1}{2}\\\Rightarrow x = \dfrac{\pi}{6}, \dfrac{5\pi}{6}[/tex]

Therefore, the answers as a comma separated list are:

[tex]0, \dfrac{\pi}{6}, \dfrac{5\pi}{6}, \pi[/tex]
