There are two cell phone plans available from Cells Phones R Us company. Plan A charges $35 a month plus $0.05 for every text me
Yuri [45]

if PLAN A is cheaper than PLAN B then,

P (A) < P (B)

30+0.01t < 20+0.05t      (subtract 0.05t from both sides)

29.95-0.04t < 19.95        (subtract 29.95 from both sides)

-0.04t < -10                      (divide both sides by -0.04)

t > 250

So plan A is cheaper than plan B when you send more than 250 texts.

Hope it helps.

iogann1982 [59]

Answer:

0.1469

Step-by-step explanation:

Given from the question;

Mean=8.4 hrs=μ

Standard deviation=1.8 hrs=δ

Sample size, n=40

Let  x=8.7

z=(x-μ)÷(δ÷√n)  

Find z(8.7)

z=(8.7-8.4)÷(1.8÷√40)

z={0.3×√40}÷1.8=1.05409

z=1.0541

Read from the  standard normal probabilities table

P(z>1.0541)

=0.1459

How to solve this (b) ???​
vladimir1956 [14]

(b). → Simplify: [{5^(x-+1) + 5^x}/{6×5^x}]

= [{5^(x+1+x)}/{6×5^x}]

= [{5^(2x+1)}/{6×5^x}]

= [{5^(2x+1)}/{6×5^x}]

= [{5^(2x+1-x)}/6]

= [{5^(x+1)}/6]Ans.

(c). 4a³b²

= 4(3)³(-2)²

Since, a = 3 and b = -2.

so,

= 4(3*3*3)(-2*-2)

= 4(27)(4)

= 108(4)

= 432Ans.
