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

Answer:

$y = \dfrac{3 + 6\sqrt{2}}{4} ~~~\textrm{and}~~~y = \dfrac{3 - 6\sqrt{2}}{4}$

Step-by-step explanation:

$(4y - 3)^2 = 72$

$4y - 3 = \pm\sqrt{72}$

$4y - 3 = \pm 6\sqrt{2}$

$4y = 3 \pm 6\sqrt{2}$

$y = \dfrac{3 + 6\sqrt{2}}{4}~~~\textrm{or}~~~y = \dfrac{3 - 6\sqrt{2}}{4}$
