VashaNatasha [74]

Answer:

D. 54%

Step-by-step explanation:

Find the relative frequency of it landing on heads by dividing 27 by 50, then multiplying it by 100

27/50

= 0.54

0.54(100)

= 54

So, the relative frequency is 54%

The correct answer is D. 54%

Jonathan collects postcards and stamps. The number of postcards in his collection is 12 more than 3/4 the number of stamps. He h

zimovet [89]

For this case we define the following variable:

x: number of stamps

We now write the equation that models the problem:

$\frac {3} {4} x + 12 = 39$

From here, we clear the value of x.

We have then:

$\frac {3} {4} x = 39-12\\\frac {3} {4} x = 27\\x = (\frac {4} {3}) (27)\\x = (4) (9)\\x = 36$

Answer:

The number of stamps he has is:

$x = 36$

Answer:

$y$

Step-by-step explanation:

The graph in the attached figure

Find the equation of the dashed line

we have

points (0,2) and (5,3)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the given values

$m=\frac{3-2}{5-0}$

$m=\frac{1}{5}$

Find the equation of the dashed line in slope intercept form

$y=mx+b$

we have

$m=\frac{1}{5}$

$b=2$

substitute

$y=\frac{1}{5}x+2$

Remember that

The solution of the inequality is the shaded area below the dashed line

therefore

The equation of the inequality is

$y$

Which would be the best method to use to solve the following equation. Explain your reasoning.

s2008m [1.1K]

Answer:

x = 3 and x = -2

Step-by-step explanation:

The given equation is :

$x^2-x-6=0$

We need to solve the given equation.

We can solve it using Completing the Square method.

We take two numbers such that their product is -6 and sum is -1.

So,

$x^2-x-6=0\\\\x^2+2x-3x-6=0\\\\x(x+2)-3(x+2)=0\\\\(x-3)(x+2)=0\\\\x=3\ and\ x=-2$

so, the values of x are 3 and -2.
