Answer:

Option 2: 5.34 is the correct answer.

Step-by-step explanation:

As it can be seen that the given triangle is a right-angled triangle.

Here

Base = 12

Perpendicular = x

θ = 24°

We can use trigonometric ratios to find the value of x. We have to choose a trigonometric ratio which involves base and perpendicular as we only know these two and the angle in the triangle

So,

[tex]tan 24 = \frac{perpendicular}{base}\\0.4452 = \frac{x}{12}\\x = 0.4452*12\\x = 5.3424[/tex]

Rounding off to nearest hundredth

x = 5.34

Hence,

Option 2: 5.34 is the correct answer.

Which is the equation of a line that has a slope of 1/2 and passes through point (2, -3) ?​

Answers

Slope form: y = mx + b
mx = 1/2x
y = 1/2x + b
Plug in points to find b
-3 = 1/2(2) + b
-3 = 1 + b
b = -4
Final equation: y = 1/2x - 4

Let f(x) = 5x + 4 and g(x) = x2 - 4. Find the following.
(gof)(-2)

Answers

Answer:

(g ￮ f)(-2) = 32

Step-by-step explanation:

Given

[tex]f(x)=5x+4[/tex]

[tex]g\left(x\right)=x^2-4[/tex]

We have to evaluate (g ￮ f)(-2), so first we will evaluate f(-2) then use this value to evaluate g(x).

Finding f(-2)

[tex]f(x)=5x+4[/tex]

[tex]f(-2) = 5(-2)+4[/tex]

          [tex]= -10 + 4[/tex]

          [tex]= -6[/tex]

Then

[tex]g\left(-6\right)=\left(-6\right)^2-4[/tex]

          [tex]=36-4[/tex]

          [tex]= 32[/tex]

Therefore,

(g ￮ f)(-2) = 32

A shop sells 20 different flavors of ice cream, in how many ways can a customer choose4 ice cream cones (one dip of ice cream per cone, please) if they:_________(a) are all of different flavors.(b) are not necessarily of different flavors.(c) contain only 2 or 3 flavors.(d) contain 3 different flavors.

Answers

Answer:

a.4845ways.

b. 14535ways.

c. 3990ways

d. 1140ways

Step-by-step explanation:

Given data:

No of flavors available to customers = 20.

Solution:

This is permutation and combinations problem,

(a) how many ways can the customers choose 4 different ice creams if they are all of different flavors.

20C4

= n!/(n-k)!)k!

= 20!/(20-4)!)4!

= 20!/(16)!)4!

= 4845ways.

b) are not necessarily of different flavors

Let’s say any two same flavors can be chosen.

20C4 * 3!/2!

= 4845 * 3

= 14535ways.

c) contain only 2 or 3 flavors.

= 20C3 * 3!/2!

= 1140 * 3

= 3420

20C2 * 3

= 190 * 3

= 570.

No of 2 or 3 different flavors

= 3420 + 570

= 3990ways.

d) contain 3 different flavors.

20C3

= n!/(n-k)!)k!

= 20!/(20-3)!)3!

= 1140ways.

(Enter your probability as a fraction.)

Answers

Answer:

_____Favor __Oppose__ No Opinion__Total

Demo 320___ 150 ______50 _______ 520

Repub 125___ 345 _____ 10 _________480

Total 445 ___495 ______60 ________ 1000

what is the probability that a citizen selected at random will favor reducing industries' carbon emissions, given that the person is a Republica

From the table provided :

n(favor n republican) / n(Total)

Number of republican who are in favor = 125

Total number of persons = 1000

Hence,

Solve the inequality 3(x+1)<18

Answers

Answer:

3(x+1)<18

3x+3<18

3x<15

x<5

Step-by-ste3(x+1)<1p explanation:

3(x + 1) < 18

First we have to apply the Distribution Property to the left side of the inequality.


3(x + 1) = 3(x) + 3(1)

3x + 3 < 18


Now we get the term 3x alone by subtracting 3 on both sides.


3x + 3 - 3 < 18 - 3

3x < 18


Now all we have to do is get x alone to find out what would be the values of x is. And since the number we are dividing by isn’t a negative, we don’t have to flip the sign.


3x/3 < 18/3


x < 6
