I = PRT
$360 = $8000 x R X 1
$360 = $8000 X R
$360/$8000 X R /$8000
0.045 = R
R= 0.045 * 100

Linda Barnes has learned from prior studies that one out of five applicants gets admitted to top MBA programs in the country. Sh

LenKa [72]

Answer: 126

Step-by-step explanation:

As per given , we have

Prior Population proportion : $p=\dfrac{1}{5}=0.2$

Significance level : $\alpha=1-0.95=0.05$

Critical value for 95% confidence interval (using the z-value table) = $z_{\alpha/2}=1.96$

Margin of error (maximum error): $E=7\%=0.07$

Formula to find the sample size :

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2\\\\ n=0.20(1-0.20)(\dfrac{1.96}{0.07})^2\\\\ n=125.44\approx126$

Therefore , the required minimum sample size = 126

If your string is 95 cm long and the second string is 650 mm, then how many mm are the two line segments together

Fed [463]

Answer:

1600mm

Step-by-step explanation:

total length of the line segment = length of the first string + length of the second string

to add the strings together, convert the length of the first string to millimetre

1cm = 10mm

95 x 10 = 950mm

950mm + 650mm = 1600mm
