BartSMP [9]

Answer: (24.02,25.98)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given : Sample size : n= 100

Sample mean : \overline{x}=25\text{ hours}

Standard deviation : \sigma=5\text{ hours}

Significance level : \alpha: 1-0.95=0.05

Critical value : z_{\alpha/2}=1.96

The confidence interval for population mean is given by :-

\overline{x}\pm\ z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=25\pm(1.96)\dfrac{5}{\sqrt{100}}\\\\=25\pm0.98\\\\=(25-0.98,\ 25+0.98)=(24.02,25.98)

Hence, the 95% confidence interval for the population mean of training times is (24.02, 25.98).

What is the slope of a line parallel to the graph of y-2=4(x+1)
Brrunno [24]

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

Solve for x.<br> -1+4x5= 3
spin [16.1K]

Answer:

x = 0.2 \: or \:  \frac{1}{5}

Step-by-step explanation:

- 1 + 4x.5 = 3

=  > 20x - 1 = 3

=  > 20x = 3 + 1 = 4

=  > x =  \frac{4}{20}  =  \frac{1}{5}  = 0.2
