Answer:

the solution is the point $(2,4)$

Step-by-step explanation:

we have

$13x-6y=2$ ------> equation A

$3x-4y=-10$ ------> equation B

we know that

The solution of the system of equations is the intersection point both graphs

Using a graphing tool

The intersection point is the point $(2,4)$

see the attached figure

therefore

the solution is the point $(2,4)$

What method would you choose to solve the equation 2x2 – 7 = 9? Explain why you chose this method.

Kisachek [45]

This is a quadratic equation . We order to equate to zero

2x² – 7 = 9

2x² - 7-9 = 0
2x² - 16 = 0

This equation is a binomial
2* (x² - 8) = 0
We choose the simplest method . The equation with practice it can be calculated in the memory

The product is equal to 0 if one of the factors is zero

2≠0 ∨ x² - 8 = 0
x² = √8
x = √8 ∨ x= - √8

Answer : x = √8 ∨ x = -√8

Suppose that six individuals are interested in taking part in a study relating BMI to a number of health outcomes. The following

posledela

Answer:

a) Mean = 27.65

Median = 27.645

b) Relative Frequency = 33.33%

Step-by-step explanation:

We are given the following data set:

25.78, 21.06, 36.54, 29.51, 18.96, 34.05

a) Mean and Median

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{165.9}{6} = 27.65$

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$
