Plz help me solve this inequality! I’m timed!

The probability that none of the coupons reveal a discount of 50% is 0.28.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Binomial distribution states that,

P = [tex]^nC_kp^k q^{n - k}[/tex]

Now,

30% of the coupons will reveal a discount of 50%.

This means,

p = 30% = 0.3

q = 70% = 0.7

Now,

Select 10 coupons:

n = 10

Now,

The probability that none of the coupons reveal a discount of 50%.

[ None means k = 0 ]

So,

P(k) = [tex]^nC_kp^k q^{n - k}[/tex]

P(0) = [tex]^{10}C_0(0.3)^0 (0.7)^{10 - 0}[/tex]

P(0) = 10 x 1 x 0.028

P(0) = 0.28

Thus,

The probability that none of the coupons reveal a discount of 50% is 0.28.

Answer - the answer should be: -3x+4

down below is how i did it,

Step-by-step explanation:

use the formula mx+b=y

y is f(x)

m = -3

x = x

b = 4

so,

mx+b is -3x+4

A linear function is the function of a straight line.

The linear function is: [tex]\mathbf{f(x) = -3x + 4}[/tex]

The given parameters are:

[tex]\mathbf{f(2) =-2}[/tex]

[tex]\mathbf{f(1) =1}[/tex]

Calculate the slope (m)

[tex]\mathbf{m = \frac{f(b) - f(a)}{b -a}}[/tex]

So, we have:

[tex]\mathbf{m = \frac{-2-1}{2 -1}}[/tex]

[tex]\mathbf{m = \frac{-3}{1}}[/tex]

[tex]\mathbf{m = -3}[/tex]

The linear function is then calculated as:

[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]

This gives

[tex]\mathbf{y = -3(x - 1) + 1}[/tex]

[tex]\mathbf{y = -3x + 3 + 1}[/tex]

[tex]\mathbf{y = -3x + 4}[/tex]

Rewrite as:

[tex]\mathbf{f(x) = -3x + 4}[/tex]

Hence, the linear function is: [tex]\mathbf{f(x) = -3x + 4}[/tex]

Answer:

One solution

Step-by-step explanation:

The slope and y-intercept is different on both sides

The given equation has one solution which is the variable x = -27.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.

The equation is given in the question,

0.4(5x – 15) = 2.5(x+3)

Multiply both sides by 10

0.4(5x – 15) × 10=25(x+3) × 10

Refine

4(5x–15) =2.5(x+3)

Expand 4(5x-15): 20x-60

Expand 25(x+3): 25x+75

20x-60 = 25x+75

Add 60 to both sides

20x-60+60 = 25x+75 +60

Simplify the above equation,

20x=25x+135

Subtract 25x from both sides

20x-25x = 25x+135-25x

-5x  = -135

Divide both sides by -5

-5x / -5 = -135/5

x = -27

Therefore, the given equation has one solution which is the variable x = -27.

Answer: angle V = 41 degrees  (choice B)

======================================================

Explanation:

We're told that RS = ST = RT. This means triangle RST has all three sides equal to one another. This triangle is equilateral. Each interior angle is 60 degrees. This is because each angle is y, and y+y+y = 180.

Since each angle of triangle RST is 60 degrees, this means angle STR is 60 degrees.

Let z be the measure of angle UTV. Note how

(angleSTR)+(angleUTV) = 180

60+z = 180

z = 180-60

z = 120

Making angle UTV to be 120 degrees

------------------------------------

Now we can focus on triangle UTV since we have expressions for each interior angle

Add up those angles, set the sum equal to 180, solve for x

U+T+V = 180

(4x-9)+(120)+(5x+6) = 180

9x+117 = 180

9x = 180-117

9x = 63

x = 63/9

x = 7

Use that x value to find the missing angle measures

angle U = 4x-9 = 4*7-9 = 28-9 = 19 degrees

angle V = 5x+6 = 5*7+6 = 35+6 = 41 degrees

Note how

U+T+V = 19+120+41 = 180

which helps confirm our answer.

Answer:

The answer you selected is correct.

Step-by-step explanation:

The answer has to be greater than 0 so the bottom graph is correct.

The graph that represents the solution set for the quadratic inequality is option (C) is the correct answer.

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is the condition of being unequal. It is used most often to compare two numbers on the number line by their size.

For the given situation,

The quadratic inequality is x^2 + 2x + 1 > 0

[tex]x^2 + 2x + 1 > 0[/tex]

⇒ [tex](x+1)(x+1) > 0[/tex]

Plot this function on the graph as shown below.

From the graph, the function extends in both positive and negative direction at x = -1.

On number line, we can denote it as x = -1 and extends up to infinity on both sides.

Hence we can conclude that the graph that represents the solution set for the quadratic inequality is option (C) is the correct answer.

Now, divide the equation

5/9 will be ur answer

Answer:

No

Step-by-step explanation:

[tex]\frac{2}{3} \frac{5}{6}[/tex]

2 goes into 6 3 times so it would be the same as 1 going into 3 3 times.

[tex]\frac{1}{3} \frac{5}{3}[/tex]

Since 3 doesn't go into 5 at all (and by that I mean a whole number) you don't change it.

Multiplying 1/3 and 5/3, you would get 5/9.

Multiplying 2/3 and 5/6, you would get 10/18, which simplifies to 5/9.

That is kind of how cross multiplying works.

Answer:

x= 33

y= 106

Step-by-step explanation:

4x-58=74

+58 +58

4x=132

4x/4=132/4

x=33

If two parallel lines intersect another two parallel lines then all corresponding angles will be the same thus the value of y is 106° and x is 33°.

Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.

It is known that the If two parallel lines intersect another two parallel lines then all corresponding angles will be the same.

Therefore, 74 = 4x - 58

4x = 132

x = 33.

Since 74° and the adjacent angle of y° are made by two parallel lines on the same line thus both will also same.

The adjacent angle of y = 74°

Since,  adjacent angle + y = 180°

y = 180 - 74 = 106°.

Hence "If two parallel lines intersect another two parallel lines then all corresponding angles will be the same thus the value of y is 106° and x is 33°".
