Answer:
8.4 (42/5)
well you know that 1/4 as a decimal is .25 so take the 5 and put it in front of the .25, so you will have 5.25. And 5/8 as a decimal is .625. then just divide them by using long division or a calculator.
Answer:
Domain: (-∞, ∞)
Range: [-2, ∞)
Step-by-step explanation:
The domain of any parabola is (-∞, ∞)
The range of this parabola is [-2, ∞) because the vertex is at (-2, -2).
The given expression has 3 terms.
The terms are the entities that are connected by addition or subtraction in a polynomial expression.
The constant term is the one which does not have any variable attached to it. In this case the constant is -7. Do not forget to consider the sign of constant term in such case.
So the answer to this question is
1st blank: 3
2nd blank: -7
Answer:
4
Step-by-step explanation:
Basándonos en el hecho de que 2 rectas paralelas L1 y L2 son paralelas como lo indica el problema sabemos que m1=m2
por lo tanto si resolvemos la ecuación punto-pendiente que tenemos alli
y-2=4(x+1)
y-2=4x+4
y=4x+4+2
y=4x+6
De esta forma tendríamos la tan conocida ecuación de una recta
y=mx+b
Donde "m" es la pendiente de dicha recta y "b" es el punto de interseccion con el eje y
por lo tanto en este caso la pendiente m=4
At 95% confidence interval, the z score is 1.96. Using the
formula:
Confidence Interval = x ± z s / sqrt (n)
where x is the average time served, s is standard deviation
and n is number of samples
Confidence interval = 7.5 ± (1.96 * 3) / sqrt (400)
Confidence interval = 7.5 ± 0.294
<span>Confidence interval = 7.206 to 7.794</span>
