Answer:

21%

Step-by-step explanation:

To find the decrease subtract 68 from 86

86 - 68 = 18

Divide 18 by the original temperature -

18/86 = 0.209

Multiply 0.209 by 100 to find the percent -

20.9%

Round to the nearest percent -

21%

Step-by-step explanation:

$qr - pr \: + qs - ps$

$r(q - p) + s(q - p)$

$(r + s)(q - p)$

${x}^{2} + y - xy - x$

${x}^{2} - x - xy + y$

$x(x - 1) - y(x - 1)$

$6xy + 6 - 9y - 4x$

$- 4x + 6 + 6xy - 9y$

$2( - 2x + 3) - 3y( - 2x + 3)$

$(2 - 3y)( - 2x + 3)$

${x}^{2} - 2ax - 2ab + bx$

$x(x - 2a) - b(x - 2a)$

$-(x +b)(2a-x)$

$axy + bcxy - az - bcz$

$xy(a + bc) - z(a + bc)$

$(xy - z)(a + bc)$

Men’s heights are normally distributed with a mean of 71.8 inches and a standard deviation of 3.4 inches. A social organization

nadya68 [22]

Answer: 2.28%

Step-by-step explanation:

μ = 71.8

σ = 3.4

X < 65

P(X < 65) = P (Z < 65 - 71.8/3.4) = P (Z < -2)

According to the table for the normal distribution attached, it will give us

P (z < Z < 0), this way, to find the P(Z < z), we need to do 0.5 - P:

0.5 - P(-2 < Z < 0) = 0.5 - 0.4772 = 0.0228

In percentage: 0.0228*100 = 2.28%
