What is the slope of a line perpendicular to
y =3/4 x+2
Answer:
-3/4 slope
Step-by-step explanation:
y = 3/4 x +2 has a slope of 3/4
Perpendicular lines intersect.
So the slope of the perpendicular line must be opposite.
Distance and slope for (0,1) & (2,2)
Answer: slope is 1/2 Distance is √ 5 or 2.236
Step-by-step explanation:
slope -
(0,1);(2,2)
(x1,y1)=(0,1)
(x2,y2)=(2,2)
Use the slope formula:
m= y2−y1/ x2−x1
= 2−1 /2−0
= 1 /2
4x + 2y = –18
y=mx+b

The standard deviation is 2.08.
What is Standard Deviation?A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
We have the data,
X : 0 1 2 5 10
P(X) : 0.4 0.2 0.2 0.1 0.1
CF : 0.4 0.6 0.8 0.9 1
Sum of fx = 2.5
Mean = 2.5
Deviation X = -2.1 -2.3 -2.1 -2 -1.5
X² = 4.41 5.29 4.41 4 2.25
fX² = 1.764 1.058 0.882 0.4 2.225
Now, standard deviation
= √4.329/1
= 2.08

Tres números naturales consecutivos son tales que el cuadrado del número intermedio es 15 más que la suma de los otros dos. Sea mmm el número intermedio. Escribe una ecuación para mmm. Nota: no necesitas ingresar la ecuación en forma cuadrática.
Responder:
m² = 15 + 2m
Explicación paso a paso:
Tres números naturales consecutivos:
Número medio = m
Los otros dos números son; m - 1; m + 1
Por tanto, tenemos:
m - 1, m, m + 1
Cuadrado de m = (m - 1) + (m + 1) + 15
m² = 15 + (m - 1 + m + 1)
m² = 15 + (m + m)
m² = 15 + 2m
