Gala2k [10]

Answer:

G= 93 to 147

Step-by-step explanation:

From the question we are told that

Mean x = 120

Standard deviation o = 9

Percentage for men =99.75%

Generally the empirical rule 68%,95% and 99.7% of data value lay b/w 1,2,3 standard deviation of mean

Standard deviation n= 9

Mean x= 120

Generally the interval of systolic blood pressure for middle 99.7 of male G is mathematically given as

G = mean + 3 * o

G = 120 + 3 * 9

G = 93 to 147

(iii) (3x + 4)(3x - 5)

kiruha [24]

Answer:

$x_{1}=-\frac{4}{3}\\x_{2}=\frac{5}{3}\\$

Step-by-step explanation:

$(3x+4)(3x-5)=9x^{2} -15x+12x-20=9x^{2} -3x-20\\\\9x^{2} -3x-20=0\\\\D=b^{2} -4ac=(-3)^{2}-4*9*(-20)=9+720=27^{2} \\\\x_1_,_2=\frac{-b +_- \sqrt{D} }{2a}\\\\x_1=\frac{3-27}{18}=\frac{-24}{18} =-\frac{4}{3}\\\\x_2=\frac{3+27}{18}=\frac{30}{18} =\frac{5}{3} \\\\$
