Let’s suppose PT is equal to TQ
Therefore the equations will be equal
3x+7=8x-8
3x-8x=-7-8
-5x=-15
x=3
We have found x now we will substitute it into each equation
PT=3(3)+7
PT=9+7
PT=16
Then we will substitute the second equation
TQ=8(3)-8
TQ=24-8
TQ=16
And here is the answer please correct me if I’m wrong

Answer:
6,7
Step-by-step explanation:
Answer:
a. 0.9049
b. 0.2297
c. 0.8473
Step-by-step explanation:
Given U = 46.7, SD = 1.75
and Z = (U - X)/sd
(a). We want to find P(X<=49)
P(X<=49) = P(Z<= 49-46.7/1.75)
= P(Z<= 1.31)
= 0.90490
~= 0.9049
(b) P(X>=48) = P(Z>=48-46.7/1.75)
=P(Z>=0.7429) = 1 - P(Z<=0.7429)
= 1 - 0.77035
= 0.22965
=0.2297
(c) The required probability is given by P(U±2.5).
P(46.7±2.5) = (44.2<= X <=49.2)
= P( 44.2<= Z <= 49.2)
= P(44.2 - 46.7/1.75 <= Z <= 49.2- 46.7/1.75)
= P( - 1.4286 <= Z <= 1.4285)
= P(1.4285) - P(-1.4285)
= P(1.43 ) - P(-1.43)
= 0.92364 - 0.07636
= 0.8473
