xxMikexx [17]

formula = height = 12+10t

where t = number of weeks

so for t10

 height = 12+10(10) = 12+100 = 112 cm

for t12

height = 12+10(12) = 12 +120 = 132 cm

A construction firm bids on two different contracts. Let E1 be the event that the bid on the first contract is successful, and d
NARA [144]

Answer:

(a) 0.56

(b) 0.06

(c) 0.94

Step-by-step explanation:

P(E1) = 0.7 and P(E2) = 0.8

(a) The probability that both bids are successful is given by the product of the probability of success of each bid:

P(E1\ and\ E2) = 0.7*0.8=0.56

(b) The probability that neither bid is successful is given by the product of the probability of failure of each bid:

P(not\ E1\ and\ not\ E2)= (1-P(E1))*(1-P(E2))\\P(not\ E1\ and\ not\ E2)=0.3*0.2=0.06

(c) The probability that the firm is successful in at least one of the two bids is given by the sum of the probability of success of each bid subtracted by the probability that both bids are successful:

P(E1\ or\ E2)=P(E1)+P(E2) - P(E1\ and\ E2)\\P(E1\ or\ E2)=0.7+0.8-0.56\\P(E1\ or\ E2)=0.94

Answer this for me plz.?
Elis [28]

Step-by-step explanation:

Length = x-3

width = x+8

Area of the rectangle = 60 inch²

(x-3)(x+8)=60

x²+8x-3x-24=60

x²+5x-24=60

x²+5x-84=0

x²+12x-7x-84=0

x(x+12) - 7(x+ 12) =0

(x+12)(x-7)= 0

x= -12 or, x= 7

Measure of sides of rectangle can never be negative.

Answers:

Therefore,

x=7

Dimensions

length =7-3

=4 inches

width = 7+8

=15 inches
