A 2-column table with 5 rows. Column 1 has entries x, x, x, x, Total 100 percent. Column 2 has entries 5 dollars, 5 dollars, 5 dollars, 5 dollars, Total 20 dollars. Mia bought a poster that was discounted $5 from an original price of $20. Which equation models how Mia can find the percent of discount? $5 = x ?- $20 $5($20) = x $5 = $20(x) $5(x) = $20

Answer:

y=7.5x, y=9.25x, y=6x

Step-by-step explanation:

on the first table we have for 2 tikets $ 15 so the price for one ticket (also known as unit price) is 15/2= $ 7.5

the equation for the price of ticket must be

y= 7.5 x (where y is price you pay for x number of tikets)

on the second table you can pick that you have $37 for 4 tikets so unit price is 37/4= $9.25 per one ticket

y=9.25x

last table $12 for 2 tikets so for one ticket is 12/2=$6

y=6x

Answer:

20

Step-by-step explanation:

2(a+3b)=2(10)

The value of 2a + 6b is 20.

To find the value of 2a + 6b, we can use the given equation:

a + 3b = 10

Now, we want to find 2a + 6b, which is simply twice the value of "a + 3b."

2a + 6b = 2(a + 3b)

Now, substitute the value of "a + 3b" from the given equation:

2(a + 3b) = 2(10)

2a + 6b = 20

So, the value of 2a + 6b is 20.

Answer:

The answer is B

Step-by-step explanation:

[-6,2]

The solution to the inequality is [–6, 2]. Then the correct answer is option B.

Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

The inequality is solved as:-

x⁴ + 4x³ ≤ 12x²

x² ( x² + 4x ) ≤ 12x²

x² + 4x ≤ 12

x² + 4x - 12 ≤ 0

x² + 6x - 2x + 12 ≤ 0

Equate the factors to zero.

( x + 6 ) ( x - 2 ) = 0

x =( -6 , 2 )

Hence, the solution is x = ( -6, 2 ).

Answer:

0.2

Step-by-step explanation:

Given that:

P(particleboard with excessive bark) = 0.15

The P(that particleboard do not have excessive bark) = 1 - 0.15

i.e the population proportion number of success p = 0.85

The sample size (n) is given to be = 1000

To find the P(X ≥ 860)

Since the sample size is large, we will apply the normal approximation of binomial distribution to treat this question.

The population mean [tex]\mu = n \times p[/tex]

[tex]\mu = 1000 \times 0.85[/tex]

[tex]\mu =850[/tex]

The population standard deviation [tex]\sigma = \sqrt{n*p(1-p)[/tex]

[tex]\sigma = \sqrt{1000*0.85*(1-0.85)}[/tex]

[tex]\sigma = \sqrt{1000*0.85*(0.15)}[/tex]

[tex]\sigma = \sqrt{127.5}[/tex]

[tex]\sigma = 11.2916[/tex]

Let X be the random variable which obeys a normal distribution;

Then;

[tex]P(X \ge 860) = P(Z\ge \dfrac{x- \mu}{\sigma})[/tex]

[tex]P(X \ge 860) = P(Z\ge \dfrac{860- 850}{11.2916})[/tex]

[tex]P(X \ge 860) = P(Z\ge \dfrac{10}{11.2916})[/tex]

P(X ≥ 860) = P(Z ≥ 0.8856)

P(X ≥ 860) = 1 - P(Z ≤ 0.8856)

From  z table

P(X ≥ 860) = 1 - 0.8122

P(X ≥ 860) = 0.1878

P(X ≥ 860) [tex]\simeq[/tex] 0.2

Thus, the probability of having more than 860 bark-free chips in a batch of 1,000 = 0.2

Step-by-step explanation:

100 % edmentum  

The solutions of the equation are x=-3+√42 and x=-3-√42.

The given quadratic equation is 2x²+12x=66.

Completing the Square is a method used to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial.

Now, 2x²+12x=66 can be written as x²+6x-33=0

Add and subtract (b/2)² to the equation.

That is x²+6x-33+9-9=0

⇒x²+6x+9=42

⇒(x+3)²=42

⇒(x+3)=±√42⇒x=±√42-3

Therefore, x=-3+√42 and x=-3-√42.

The required value of f(x) when x = 0.5 is 16.

Given,

f(x) varies directly with x .

f(x)=160 when x = 5.

We have to find f(x) when x = 0.5

According to the question ;

A function f(x) that varies directly with x. Direct variation is a case of variation expresses as the following form:

f(x) = kx

The value k is a nonzero constant greater than zero and is called the constant of variation.

This indicates that f(x) increases as x increases.

 So,

    f( x ) = kx

      [tex]k = \frac{f (x) }{x}\\\\ k = \frac{f(5)}{5}[/tex]

       [tex]k = \frac{160}{5}[/tex]

     k = 32  

When x = 0.5,

Then ,  f(x) = 32x

           f(x) = 32(0.5)

           f(x) = 16

The required value of  f(x) when x = 0.5 is 16.
