Z = (X-Mean)/SD
<span>z1 = (580-600)/20 = - 1 </span>
<span>z2 = (620-600)/20 = + 1 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean +/- 1*SD covers 68% of the values </span>
<span>Therefore, required percent is 68%
hopes this help :) :D :)</span>
Answer:
50 =c×d
Step-by-step explanation:
Answer:
5.4
Step-by-step explanation:
Using the pythagorean theorem (a^2 + b^2 = c^2), we can do 2^2 plus 5^2, which is 4 + 25, which simplifies to 29. Now we have 29 = c^2
In order to find c (the hypotenuse), we need to take the square root of both sides to find c. Thus, c = sqrt 29 or 5.385...
Hope this helps!
Answer:
d.160
Step-by-step explanation:
83% of 194 is 161.02 the closest one is 160 so that would be the best estimate.
m <3 = 52 °
Explicación paso a paso:
Puntos para recordar
1). El rombo es un paralelogramo. Los ángulos opuestos son suplementarios.
2). Las diagonales bisecan los ángulos de cada esquina.
3). Los ángulos alternos internos son iguales.
4). Todos los lados son iguales
Para encontrar la medida de <3
De la figura podemos ver un paralelogramo.
Se da que, n <3 = 80
Sabemos que m <1 = m <3
Por propiedad de suma de ángulos,
m <1 + m <1 + m <3 = 180
3 * m <1 = 180 - 80 = 100
<m1 = 100/2 = 50
Por lo tanto m <3
