Answer:
Z = (pd + 59)/(2-p)
Step-by-step explanation:
to solve for z in the -p(d+z)=-2z+59 expression, we would open the bracket and then evaluate for the exact value of z
solution
-p(d+z)=-2z+59
-pd - pz = -2z + 59
collect the like terms
-pd -59 = -2z + pz
-pd - 59 = -z ( 2 - p)
divide both side by ( 2-p)
-pd - 59 /2-p = -z
since we are to solve for z and not -z , so we would multiply both sides by - sign
- (-pd - 59)/2-p = -(-z)
pd + 59/2-p = z
therefore
Z = (pd + 59)/(2-p)
Answer: 7 texts 1 dollar, 5 texts 35 dollars
Step-by-step explanation:
if you have 49 is divisible by 7, and when you divide 49 by 7 you get 7. so 1 dollar you get 7 dollars. how do you get from 1 to five multiply 5, now multiply 7 by five to see how many texts you get for 5 dollars. im really not good at explaining i hope you get it though!!
Answer:
Allesandro got home first because the fraction isn't a whole and it's comparing Allesandro's time.

Step-by-step explanation:
Given that Rita is making a beaded bracelet. She has a collection of 160 blue beads, 80 gray beads, and 240 pink beads. We are to calculate the probability that Rita will need to pick atleast 5 beads before she picks a grey bead from her collection.
Prob for drawing atleast 5 beads before she picks a grey bead from her collection
= 1-Prob for drawing atleast one grey beed in the first 5 draws.
(Because these two are complementary events)
no of grey beeds drawn in first 5 trials is
Bi=(5,1/6)
Prob for drawing atleast one grey beed in the first 5 draws.
=1-Prob of no grey
Hence required prob=P(X=0 in first 5 draws)
= 0.4018
6th beeds onwards can be grey also.
Nearest answer is c)0.45
Answer:
difference = 3, first term = 4
Step-by-step explanation:
given, a2 = 7
a9 = 28
wkt, a2 = a + d = 7
<u>a9 = a + 8d</u><u> </u><u>=</u><u> </u><u>28</u>
- 7d = - 21
therefore d = 3
and wkt, d = a2 - a
a = 7 - 3 = 4
HOPE THIS HELPS
