Adult men have heights that a normally distributed with a mean of 69.5 inches and a standard deviation of 2.4 inches. Adult wome
Aliun [14]

Answer:

Step-by-step explanation:

From the information given:

For Adult Men

Mean \mu = 69.5

Standard deviation \sigma = 2.4

observed value X = 74

For Adult Women

Mean \mu = 63.8

Standard deviation \sigma = 2.6

observed value X = 70

Therefore ; the values for their z  scores can be obtained in order to determine who is more unusually tall within his or her respective sex

For Adult Men :

z = \dfrac{X- \mu}{\sigma}

z = \dfrac{74- 69.5}{2.4}

z = \dfrac{4.5}{2.4}

z = 1.875

For Adult Women :

z = \dfrac{X- \mu}{\sigma}

z = \dfrac{70- 63.8}{2.6}

z = \dfrac{6.2}{2.6}

z = 2.3846

Thus; we can conclude that , the women is more unusually tall within his or her respective sex

Solve the system 8y-5z=23 3y-2z=6<br><br> 100 POINTS
Hatshy [7]

Answer:

z = 21 ; y= 16

Step-by-step explanation:

first of all we have to isolate a variable.

In second expression we can obtain:

3y = 2z+6

y = 2/3 z + 2

now we have to substitute this value in the first equation and solve it

8(2/3z+2)-5z = 23

16/3z + 16 -5z = 23

16z +48 - 15z = 69

z = 21

now we have to substitute z in the second equation:

y = 2/3 (21) +2

y = 14+ 2 = 16

y = 16

Slope: -2

Step-by-step explanation:

Perpendicular slope is the negative reciprocal of the original slope.

The original slope was 1/2. Flip it. 2/1=2. Now change the sign to -2.

If QT is 9 and TP is 8 Find the length of the following:<br><br>RP<br>RT<br>RS​
anyanavicka [17]

Answer:

i. RP = 17

ii. RT = 15

iii. RS = 30

Step-by-step explanation:

Given that; QT = 9 and TP = 8.

From the diagram, join R to P. Thus RP = QP (radius of the circle)

                        RP = QT + TP

                             = 9 + 8

                         RP = 17

Applying Pythagoras theorem to triangle TRP;

             RT = \sqrt{(RP)^{2} - (TP)^{2} }

                  = \sqrt{17^{2} - 8^{2} }

                 = \sqrt{225}

                 = 15

∴           RT = 15

But, RT = TS = 15.

So that;

       RS = 15 + 15

             = 30

        RS = 30

Therefore;  RP = 17, RT = 15 and RS = 30.
