A positive number and a negative number with the same digits are opposite.
13 + -13 = 13 -13 = 0
13 to 0 is 13 units, -13 to 0 is also 13 units.
The answers are:
They are opposites.
Their sum is 0.
They are the same distance from zero on the number line.
Answer:
If a vehicle does not have 4 wheels, it is not a car.
Dont forget to give brainliest and thanks
y=2x+4
that is an equation in slope intercept form where the slope is 2 so you would go up two right 1 and the y intercept would be 4 so (0,4)
Answer:
Sample mean weight = 808080 grams
Step-by-step explanation:
The number of samples, n = 161616
The mean weight, ![\mu = 808080](https://tex.z-dn.net/?f=%5Cmu%20%3D%20808080)
Standard deviation, ![\sigma = 555](https://tex.z-dn.net/?f=%5Csigma%20%3D%20555)
The sample mean weight,
= Mean weight, ![\mu](https://tex.z-dn.net/?f=%5Cmu)
Since ![\mu_{\bar{x}} = \mu](https://tex.z-dn.net/?f=%5Cmu_%7B%5Cbar%7Bx%7D%7D%20%3D%20%5Cmu)
Sample mean weight, ![\mu_{\bar{x}} = 808080](https://tex.z-dn.net/?f=%5Cmu_%7B%5Cbar%7Bx%7D%7D%20%3D%20808080)
Answer:
x= 81°, z= 99°, y°=68°
Step-by-step explanation:
considering the part of the triangle where 36° , 63° and x° is located as ΔABC.
to find the measure of x we use angle sum property.
We know that the sum of the angles of a triangle is always 180°. Therefore, if we know the two angles of a triangle, and we need to find its third angle, we use the angle sum property. We add the two known angles and subtract their sum from 180° to get the measure of the third angle.
so,
∠A + ∠B +∠C = 180°
36° + 63° + x° = 180°
99° + x° = 180°
x° = 180 - 99
x° = 81°
When two lines intersect each other at a single point, linear pairs of angles are formed. If the angles so formed are adjacent to each other after the intersection of the two lines, the angles are said to be linear. If two angles form a linear pair, the angles are supplementary, whose measures add up to 180°.
x° + z° = 180°
81° + z = 180°
z= 180 - 81
z= 99°
considering the next part of the triangle where 13° , z° and y° is located as ΔACD
to find the measure of y we use angle sum property.
∠A + ∠C + ∠D = 180°
13° + z° + y° = 180°
13°+99°+y°= 180°
112°+ y° = 180°
y°= 180- 112
y° = 68°
