Answer:

Given that <ACB is congruent to <ABC we can infer that the triangle formed is an isosceles triangle. If B and C are both congruent and the distance from c and x and b and y are also congruent than the angles are congruent.

Step-by-step explanation:

You roll a standard number cube. Find P(number greater than 1).

sesenic [268]

Well if its a standard die then the numbers on the die would be 1,2,3,4,5,6. Since you want the probability that the number is GREATER than 1, you need to roll a 2,3,4,5, or 6. Which you have 5 total outcomes that would be successful out of 6. Makes the probability 5/6 or .833333

Complete Questions:

Create an equation with a solution closest to 0 using digits 1 to 9

_x + _ = _x + _

Answer:

See Explanation

Step-by-step explanation:

Given

_x + _ = _x + _

Required

Fill in the gap using 1 to 9 to give a result close to 0

First, you have to determine what kind of numbers that are close to 0;

In this case, I'll work with -0.4 to 0.4 because the number in this range approximate to 0;

Next, is to fill in the gaps using trial by error method

5x + 2 = 2x + 3

Checking the above expression

Collect Like Terms

$5x - 2x = 3 - 2$

$3x = 1$

Divide equation by 2

$x = 0.33$ (Approximated)

Another trial is

6x + 8 = 2x + 7

Checking the above expression

Collect Like Terms

$6x - 2x = 7 - 8$

$4x = -1$

Divide equation by 4

$x = -0.25$ (Approximated)

I'll stop here but note that, there are more expressions that can fill in the gaps

A conditional relative frequency table is generated by row from a set of data. The conditional relative frequencies of the two c

Gre4nikov [31]

The right answer for the question that is being asked and shown above is that: "D.) There is likely an association between the categorical variables because the relative frequencies are both close to 0.50." Given that a relative frequencies of 0.48 and 0.52, there will be an association between the categorical variables.

the altitude of the hypotenuse of a right triangle divides the hypotenuse into segments of lengths 14 and 8. what is the length

lisov135 [29]

Answer:

B. $4\sqrt{7}$

Step-by-step explanation:

The right triangle altitude theorem states that the altitude of a right angled triangles formed on the hypotenuse is equal to the geometric mean of the 2 line segments it creates.

This can be represented as:

$h = \sqrt{(xy)}$
