Answer:

x = 3.4

Step-by-step explanation:

given,                                  

mean = 3.7 inches                      

standard deviation =  0.5                  

we want find the value of Q₁ = ?                              

the value of x such that, P(X < x)= 0.25                                

= > P(\dfrac{X - \mu }{\sigma } < \dfrac{X - 3.7 }{0.5})=0.25

= > P(Z                      

=> \dfrac{x - 3.7}{0.5}= Z_{0.25}                

=> \dfrac{x - 3.7}{0.5}= -0.67                        

=> x = -0.67 x 0.5 + 3.7                

=> x = 3.365                      

=> x = 3.4

8(50 + 4) = 8·50 + 8·4


8(60 - 6) = 8·60 - 8·6

Find the y intercept of the straight line with the following equations y=7+3x <br><br>3y=6x+12
neonofarm [45]

y = 7 + 3x

y = 3x + 7

y = mx + b, therefore the y-intercept is 7.


3y =  6x + 12

y = 2x + 4

y = mx + b, therefore the y-intercept is 4.
