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%

Ronch [10]

Answer:

120 pears

Step-by-step explanation:

Let the  number of pears produced by Type B be x

Number of pears  produced by type A=144

  According to question

Type A produce 20% more pears than B

x+ x ×20%= 144

x+x×\frac{20}{100}= 144

\frac{100x+20x}{100}= 144

\frac{120x}{100}=144

x= 144×\frac{100}{120}

x=120 pears

Hence, Number of pears produced by B= 120 pears

Hence, the correct answer is 120 pears
