First put them into improper fractions which are 77/19 and 31/21, then multiply 77 and 31 and get 2387, and multiply the denominators 19 and 21 which is 399. Then u can put it into a simplified fraction of u wnat

The answer is 5 $\frac{56}{57}$ . 1.)Transform the mixed numbers into proper fractions. 4 $\frac{1}{19}$ = 19x4 = 76+1=77= $\frac{77}{19}$ . 1 $\frac{10}{21}$ = 21x1=21+10=31= $\frac{31}{21}$ .
2.) Multiplying two fractions. $\frac{77}{19}$ x $\frac{31}{21}$ = $\frac{2387}{399}$ . 3.) Simplifying a fraction. $\frac{2387}{399}$ = $\frac{341}{57}$ . 4.) Since the numerator greater then the denominator, convert the improper fraction to mixed number. $\frac{341}{57}$ = 56+5x57/57 = 5 $\frac{56}{57}$

$= > x + \frac{1}{3} = 9$

$\text{Add} \: - \frac{1}{3} \: \text{ on both sides ,}$

$= > x + \frac{1}{3} - \frac{1}{3} = 9 - \frac{1}{3} \\ \\ \\ \\ = > x = \frac{(9 \times 3) - 1}{3} \\ \\ \\ \\ = > x = \frac{27 - 1}{3} \\ \\ \\ \boxed{ \bold{= > x = \frac{26}{3} }} \\ \\ \\ or , \boxed{ \bold{ \: x = 8. \bar{6}}}$

Hence,

$Value \: \: \: of \: \: x \: \: is \: \frac{26}{3} \: \: \: or \: \: \: 8. \bar{6}$

Scores of an IQ test have a bell-shaped distribution with a mean of 100 and a standard deviation of 12. Use the empirical rule t

MissTica

Answer:

A) 99.7% of people have an IQ between 64 and 136.

B) 5% of people have an IQ score less than 76 or greater than 124.

C) 16% of people have an IQ score greater than 112.

Step-by-step explanation:

The Empirical Rule tells us that, in a normal or 'bell-shaped' distribution, 68% of the data is one standard deviation from the mean, 95% of the data is two standard deviations from the mean, and 99.7% of the data is three standard deviations from the mean.

A) 64 and 136 are 3 standard deviations away from the mean, so 99.7% of people have an IQ between 64 and 136.

B) 76 and 124 are 2 standard devations away from the mean, but the answer is asking what percentage is not between them. 100% - 95% gives us 5%.

C) 112 is one standard deviation away from the mean. If we want to find the percentage greater, then we can do 100% - 50% (as 112 is to the left of the mean), then we can take half of 68 to get 34%, and after subtracting 50% and 34% from the 100%, we get 16%.
