According to a human modeling project, the distribution of foot lengths of women is approximately Normal with a mean of 23.4 ce

stiv31 [10]

Answer: 22.0.6%

Step-by-step explanation:

Given : According to a human modeling project, the distribution of foot lengths of women is approximately Normal with $\mu=23.3\ cm$ and $\sigma=1.3\ cm$ .

In the United States, a woman's shoe size of 6 fits feet that are 22.4 centimeters long.

Then, the probability that women in the United States will wear a size 6 or smaller :-

$P(x\leq22.4)=P(z\leq\dfrac{22.4-23.4}{1.3})\ \ [\because z=\dfrac{x-\mu}{\sigma}]\\\\\approx P(z\leq-0.77)\\\\=1-P(z\leq0.77)\\\\=1-0.77935=0.2206499\approx0.2206=22.06\%$

Hence, the required answer = 22.0.6%

Convert 5.764764764... to a rational expression in the form of a/b where b ≠ 0.

Vladimir [108]

$5.764764764....=5.(764)-in\ European\ mathematics\\\\5.764764764....=5.\overline{764}-in\ US\ mathematics\\\\subtitute:\\\\x=5.(764)\ \ \ \ |multiply\ both\ sides\ by\ 1000\\\\1000x=5764.(764)\\\\
let's\ make\ a\ difference\ 1000x-x\ therefore\ we\ have\ the\ equation:\\\\1000x-x=5764.(764)-5.(764)\\\\999x=5759\ \ \ \ \ |divide\ both\ sides\ by\ 999\\\\\boxed{x=\frac{5759}{999}}$

$So...\ we\ have\ answer:\\\\\boxed{5.764764764...=\frac{5759}{999}}$

An angle measures 80° more than the measure of a complementary angle. What is the measure of each angle?

Rom4ik [11]

Supplementary angles sum to 180 degree

Let one angle be x

Then the other angle is x+80

Summing the 2 angle gives

x+x+80=180

2x+80=180

2x=180-80

X=50

Thus the angles are 50 degree and 50+80= 130 degree
