Answer:
y - 5 =
(x - 1)
Step-by-step explanation:
Note that
= 
Differentiate using the power rule
(a
) = na
Given
y = x
= x.
=
, then
= 

When x = 1
=
. 1 = 
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m =
and (a, b) = (1, 5), thus
y - 5 =
(x - 1) ← equation of tangent
The square root of any number is the same as that number to the 1/2 power
root(b)=b^(1/2)

Explicación paso a paso:
Dado ;
Tamaño de la muestra, n = 50
Media, xbar = 3000
Desviación estándar, s = 200
Nivel de confianza, Zcrítico al 95% = 1,96
El intervalo de confianza se define como:
Xbar ± margen de error
Margen de error = Zcrítico * s / sqrt (n)
Margen de error = 1,96 * 200 / sqrt (50)
Margen de error = 54.589
Límite inferior = (3000 - 54.589) = 2945.411
Límite superior = (3000 + 54.589) = 3054.589
(2945.411; 3054.589)
The answer is going to be 77,98
N=3 m+7
n-2 m=1 | -2 m => n=1+2m
n=3 <span>m+7
</span><span>n=1+2 m
</span>
n=n
3m+7=1+2m |-7 and -2m
m = -6
n=1+2m
n=1+2*(-6)
n=-11
(-6,-11)
