If x is greater than 6, then -7 is a solution true or false

1 answer:

4 0

If $x > 6$ then all the solutions are $x\in(6,+\infty)$ and since -7 is not a part of such interval the answer is false.

Classify the following data. Indicate whether the data is qualitative or quantitative, indicate whether the data is discrete, co

ivolga24 [154]

Answer:

Quantitative

Discrete

Ratio

Step-by-step explanation:

The number of days traveled by randomly selected employees is a quantitative variable because it can be presented meaningful numerical form and further the number of days traveled by randomly selected employees are discrete because the number of days can be counted. Now, the level of measurement for the variable "number of days traveled by employees" is ratio scale because it has a meaningful zero. Meaningful zero in this case will means that none of the day is spent on travelling.

5. Find the value of x that makes BC || DE.

s344n2d4d5 [400]

Answer:

x = -7

Step-by-step explanation:

To find the value of x, you need to set up a proportion:

$\frac{x-2}{15}$ = $\frac{x-1}{18}$

Then cross multiply:

15x - 15 = 18x + 36

Then subtract 15x from both sides:

-15 = 3x + 36

Subtract 36 from both sides:

-51 = 3x

Finally, divide both sides by 3:

x = -7

Suppose a triangle has 3 sides, 3, 4, 6 which of the following must be true

Inessa [10]

Answer:

B. the triangle in question is not a right triangle

Step-by-step explanation:

A 3-4-5 triangle is a right triangle, so this one, with its longer longest side, is an obtuse triangle. It is not a right triangle.

___

3, 4, 5 is one of the first Pythagorean triples that you learn:

3² + 4² = 5²

These are the side lengths of the smallest right triangle with integer sides. It is worthwhile to remember. This triple is used not only in many math problems (such as this one), but also in real life when it is useful to lay out a right angle.
