The distance between them = 4.93
Step-by-step explanation:
The distance between two points (x1, y1) amd (x2, y2) is 
Now putting the values of (0,2) and (4.5, 0) we get,
= 
= 4.93 (approx)
Answer:
Intervalo de confianza
= (0.294, 0.386)
Step-by-step explanation:
La fórmula para el intervalo de confianza para la proporción se da como
p ± z × √p (1 - p) / n
Donde p = x / n
De donde de la pregunta anterior
x = 136 personas
n = 400 personas
p = 136/400
p = 0.34
z = puntuación z del intervalo de confianza del 95% = 1.96
Por lo tanto,
Intervalo de confianza =
0.34 ± 1.96 × √0.34 (1 - 0.34) / 400
= 0.34 ± 1.96 × √0.34 × 0.66/400
= 0.34 ± 1.96 × √0.000561
= 0.34 ± 1.96 × 0.0236854386
= 0.34 ± 0.0464234596
Intervalo de confianza
= 0.34 - 0.0464234596
= 0.2935765404
= 0.34 + 0.0464234596
= 0.3864234596
Hence:Intervalo de confianza
= (0.294, 0.386)
X^2 = 50
Square both sides
x= √50
x= (√25)(√2)
x = 5√2
Final answer: x = 5√2 and since x is to the power of 2 you can have x = + or - <span>x = 5√2</span>
Answer:
C-(7)
Step-by-step explanation:
Given figure is a trapezoid and 21 - x is the mid segment.
Therefore by mid-segment formula of a trapezoid, we have:
21 - x = 1/2(17 + 11)
21 - x = 1/2 * 28
21 - x = 14
21 - 14 = x
7 = x
x = 7
Answer:
The slope between the points (0, -6) and (3, -2) will be:
Step-by-step explanation:
Given the points
The slope between the points (0, -6) and (3, -2) will be:
Therefore, the slope between the points (0, -6) and (3, -2) will be:
