A list of measurements in increasing order is 4, 5, 6, 8, 10, and x. If the median of these measurements is 6/7 times their arit

igomit [66]

Answer:

The value of x would be 16.

Step-by-step explanation:

In a data,

Median : middle value of the data when the data is written is ascending order.

While,

$\text{Average}=\frac{\text{Sum of all observations}}{\text{Number of the observations}}$

Here, the given data is,

4, 5, 6, 8, 10, and x

So, median = = = 7.

Number of the observations = 6,

Sum of the observations = 4+ 5+6+8+10+x = 33 + x

Thus,

Average = $\frac{33+x}{6}$

According to the question,

$\frac{33+x}{7}=7$

$33+x=49$

$x=49-33$

$x=16$

Therefore, the value of x would be 16.

Find the values for a and b that would make the equality true.

Crank

Answer:

a = - 4, b = 5

Step-by-step explanation:

Expand the left side and compare the coefficients of like terms on the right side.

- 3(2x² + ax + b)

= - 6x² - 3ax - 3b

Comparing like terms with - 6x² + 12x - 15

x - term → - 3a = 12 ( divide both sides by - 3 )

a = - 4

constant term → - 3b = - 15 ( divide both sides by - 3 )

b = 5
