IQ scores (as measured by the Stanford-Binet intelligence test) in a certain country are normally distributed with a mean of 95

forsale [732]

Answer:

13,797,339 people

Step-by-step explanation:

Given that μ = 95 and σ = 18

The total number of population is N = 323,000,000

Now, we calculate the probability that IQ is higher than 126

P(X>126) = 1 - P[Z ≤ 126 - 95 / 18]

P(X>126) = 1 - P[Z ≤ 1.72]

P(X>126) = 1 - [ NORMSDIST(1.72)] Using MS Excel

P(X>126) = 1 - 0.957283779

P(X>126) = 0.042716221

Hence, the required probability is 0.042716221

Now, we calculate the approximate number of people in the county with an IQ higher than 126

Number of people = P(X>128) * N

Number of people = 0.042716221 * 323,000,000

Number of people = 13797339.383

Number of people = 13,797,339

Therefore, the approximate number of people in the country with an IQ higher than 126 is <u>13,797,339 in population</u>

What is 4/9÷2/3 show work please!

$\frac{4}{9}$ ÷ $\frac{2}{3}$

First, apply the rule: a ÷ $\frac{b}{c}$ = a × $\frac{c}{b}$
$\frac{4}{9}$ × $\frac{3}{2}$
Second, apply the rule: $\frac{a}{b}$ × $\frac{c}{d}$ = $\frac{ac}{bd}$
$\frac{4x3}{9x2}$
Third, multiply 4 × 3 to get 12, and 9 × 2 to get 18.
$\frac{12}{18}$
Fourth, find the GCF of 12 and 18.
Factors of 12: 1, 2, 3, 4, 6, 12
Factors of 18: 1, 2, 3, 6, 9, 18
The GCF is 6.
Fifth, divide the numerator by the GCF.
$12$ ÷ 6 = 2
Sixth, divide the denominator by the GCF.
18 ÷ 6 = 3
Seventh, rewrite your fraction.
$\frac{2}{3}$

Answer as fraction: $\frac{2}{3}$
Answer as decimal: 0.6667

Multiply: (5 ft 6 in) 2.4

sergey [27]

to make it easier, convert 5 feet to x inches:

5*12=60

60+6=66

So, 66 inches.

Multiply 2.4 by 66:

2.4*66=158.4

So in inches, the answer is 158.4

In feet and inches, 13 feet and 2.4 inches.
