The manager of the commercial mortgage department of a large bank has collected data during the past two years concerning the nu

ZanzabumX [31]

The expected number of mortgages approved per week and the standard deviation of the distribution are 2.019 and 0.024 respectively.

The expected number of mortgages approved per week :

Mean = (Σfx ÷ Σf)

Expected Number approved = 210 ÷ 104 = 2.019

Hence, it is expected that 2.019 mortageahes would be approved per week.

The standard deviation :

Variance = [Σ(Xi - x)² ÷ Σf]

Standard deviation = √Variance

Variance = (59.5414 ÷ 104) = 0.0005698

Standard deviation = √0.0005698

Standard deviation = 0.024

Therefore, the expected value and standard deviation are 2.019 and 0.024 respectively.

Answer:

$ax^2 = 48\\a = \frac{48}{x^2}$

$ax^2 = 48\\x^2 = \frac{48}{a} \\x = \frac{\sqrt{48} }{\sqrt{a} } \\x = \frac{4\sqrt{3} }{\sqrt{a}} \\x = \frac{4\sqrt{3a} }{a}$

4 7/12 + 2 1/12 what is the estimate answer

Pani-rosa [81]

$4 \frac{7}{12} = \frac{12*4+7}{12} = \frac{55}{12} \\ \\ 2 \frac{1}{12} = \frac{2*12+1}{12} = \frac{25}{12} \\ \\ \frac{55}{12} + \frac{25}{12} = \frac{80}{12} \\ \\ \frac{80 :4}{4:4} = \frac{20}{3}$
