Answer:
-9
Step-by-step explanation:
with the equation y=mx+b, m equals the slope and b equals the y-intercept. whatever is in the place of m is the slope. in this case, -9.
Answer:
Tenemos 75 postulantes, y sus notas están en el rango desde 16 hasta 20.
1) si el grupo es homogéneo y todos tienen la misma nota, entonces todos van a tener la nota media en el rango (16, 20)
Para encontrar esta nota calculamos la suma entre ambos extremos y lo dividimos por 2.
Media = (16 + 20)/2 = 36/2 = 18
La nota sería 18.
2) entre 16 y 20 tenemos:
16, 17, 18, 19 y 20
tenemos 5 notas distintas, entonces si agrupamos a los estudiantes por nota, tendríamos 5 grupos.
3) En una distribución normal, el grupo mas grande debería coincidir con la media del intervalo. Ya sabemos que la media es 18, entonces es esperable que la nota del grupo mas grande sea 18.
4) Si los estudiantes se ordenan en fila según notas tendríamos:
Fila con nota 16
fila con nota 17
fila con nota 18
fila con nota 19
fila con nota 20
Podemos ver que la fila del medio es el grupo con nota de 18
For step one, it’s Graph A because it’s going through the origin
For step two, the rate of change is -3, you can find the answer by using the rise/run method by going down three and going right once.
For step 3, the dividing method doesn’t work because -1 divided by 2 isn’t 0.
For step four, go to the point (-2,-4) and from that point draw a line up three units. From there draw a line right two units, and you should stop at -1 on the 6-axis
I hope this helped!
Answer:
The length of the other leg of this right angled triangle is 30 inches.
Step-by-step explanation:
We are given the following in the question:
A right angles triangle with the hypotenuse of 34 inches and the length of one of its legs is 16 inches.
Pythagoras theorem:
- The sum of of square of two sides of a triangle is equal to the square of the hypotenuse.
Let x inches be the length of the other leg of this right triangle.
Thus, we can write the equation:
Thus, the length of the other leg of this right angled triangle is 30 inches.
Answer: The answer is A.
Step-by-step explanation:
The formula for the area of circles:
A = πr^2
Plug in the radius
A = π8^2
A = π64
A = 201.06192983/ 201 (rounded)
