The probability that she gets <em>more than 3 heads</em> is 0.3456.

There are only two possible outcomes for a fliped coin, either it is head, or it is tail. Since the result is independent of each other coins, the binomial distribution will be used.

Given the following parameters:  

  • x is the number of successes = 5 (coin flipped 5 times)
  • n is the number of trials
  • p is the probability of success on a single trial = 0.6

Using the binomial distribution formula:

P(X =x)=nC_x p^x (1-p)^{n-x}\\P(X =3) = 5C_3 \ (0.6)^3 (1-0.6)^{5-3}\\P(X =3) = 5C_3 \ (0.6)^3 (0.4)^{2}\\P(X=3)=0.3456

Hence the probability that she gets <em>more than 3 heads</em> is 0.3456.

Follow the directions to convert the analog sound wave into a digital signal. the lines on the grid intersect at various points
dmitriy555 [2]

In this exercise we have to observe the axes of the graph to associate the values ​​of X with those of Y that correspond to 0, 5, 5, -3, -5, -3, 2, 0, 0, -1, -2, 1, 1, -1, -1, -2, 2, 3, -1.

<h3>How to calculate the Cartesian plane?</h3>

Just draw two lines: one of them vertical, starting from the point until it finds the x axis; another horizontal, starting from the point until it meets the y-axis.

Then plotting the value of X on the graph we find the following for each value of X to Y:

  • X= 0 ; Y= 0;
  • X= 1 ; Y= 5;
  • X= 2 ; Y= 5;
  • X= 3 ; Y= -3;
  • X= 4 ; Y= -5;
  • X= 5 ; Y= -3;
  • X= 6 ; Y= 2;
  • X= 7 ; Y= 0;
  • X= 8 ; Y= 0;
  • X= 9 ; Y= -1;
  • X= 10 ; Y= -2;
  • X= 11 ; Y= 1;
  • X= 12 ; Y= 1;
  • X= 13 ; Y= -1;
  • X= 14 ; Y= -1;
  • X= 15 ; Y= -2;
  • X= 16 ; Y= 2;
  • X= 17 ; Y= 3;
  • X= 18 ; Y= -1;

In anticipation of receiving a fertilized ovum, the lining of the uterine wall
Mariulka [41]

Every month, the lining of the uterus becomes thicker in preparation for an egg that has been fertilized to place itself there. In the event that this transpires, hormones originating from the reproductive organs will stabilize the vascular tissue of the endometrium, which in turn will offer a setting for the embryo to grow in.

This is further explained below.

<h3>What is the uterine wall?</h3>

Generally, The uterine lining grows every month in anticipation of the implantation of a fertilized ovum. When this happens, the endometrium's vascular tissue is stabilized by hormones from the reproductive organs, providing an environment for the growing fetus.

In conclusion, There are three distinct layers of muscle tissue that compose the uterine wall. The muscle fibers are intertwined with the connective tissue of blood vessels, elastic fibers, and collagen fibers, and they may run in either of three directions: longitudinally, circularly, and obliquely. As the baby grows within the uterus, this thick muscular wall begins to stretch out and eventually becomes much thinner.
