Mathematically speaking, the linear pair postulate and linear pair theorem both express the same thing.

  • A linear pair is made up of two angles, and the sum of their measures is 180°.

<h3>What is the formula for linear pairs?</h3>
  • A two-variable linear equation of the form axe + by + c, with a, b, and c all being real numbers and not equal to zero.
  • The Transitive Property states that if all real numbers x, y, and z are equal, then x=z.
  • Substituting characteristics. If x=y, then x can be swapped to y in any equation or formula.
  • Mathematically speaking, the linear pair postulate and linear pair theorem both express the same thing.
  • A linear pair is made up of two angles, and the sum of their measures is 180°.
  • Line pairs can be congruent.
  • Adjacent angles are joined by a vertex.
  • Angles that are similar cross across.
  • A linear pairing is unnecessary.

Therefore, mathematically speaking, the linear pair postulate and linear pair theorem both express the same thing.

  • A linear pair is made up of two angles, and the sum of their measures is 180°.

he blood platelet counts of a group of women have a​ bell-shaped distribution with a mean of 247.3 and a standard deviation of 6
Ulleksa [173]

Answer:

The approximate percentage of women with platelet counts within 3 standard deviations of the​ mean is 99.7%.

Step-by-step explanation:

We are given that the blood platelet counts of a group of women have a​ bell-shaped distribution with a mean of 247.3 and a standard deviation of 60.7.

Let X = <em>t</em><u><em>he blood platelet counts of a group of women</em></u>

The z-score probability distribution for the normal distribution is given by;

                                Z  =  \frac{X-\mu}{\sigma}  ~ N(0,1)

where, \mu = population mean = 247.3

           \sigma = standard deviation = 60.7

Now, according to the empirical rule;

  • 68% of the data values lie within one standard deviation of the mean.
  • 95% of the data values lie within two standard deviations of the mean.
  • 99.7% of the data values lie within three standard deviations of the mean.

Since it is stated that we have to calculate the approximate percentage of women with platelet counts within 3 standard deviations of the​ mean, or between 65.2 and 429.4, i.e;

         z-score for 65.2 =  \frac{X-\mu}{\sigma}

                                     =  \frac{65.2-247.3}{60.7}  = -3

         z-score for 429.4 =  \frac{X-\mu}{\sigma}

                                       =  \frac{429.4-247.3}{60.7}  = 3

So, it means that the approximate percentage of women with platelet counts within 3 standard deviations of the​ mean is 99.7%.

O centroid

Step-by-step explanation:

In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has three medians, one from each vertex, and they all intersect each other at the triangle's centroid.

vesna_86 [32]

Answer:

Step-by-step explanation:

V=4/3πr³

v = 1.33*3.142*9³

v = 3046.39in³

New scale = 3046.39*1.5

= 4,569.59in³
