The URS construction company has submitted two bids, one to build a large hotel in London and the other to build a commercial o

topjm [15]

Answer: Our required probability is 0.55.

Step-by-step explanation:

Since we have given that

Probability that chance of winning the hotel bid = 40%

Probability that no chance of winning the hotel bid = 100-40=60%

Probability that chance of winning the office building bid = 25%

Probability that no chance of winning the office building bid = 100-25 = 75%

So, Probability that the company will win at least one contract is given by

$0.4\times 0.75+0.6\times 0.25+0.4\times 0.25\\\\=0.55$

Hence, our required probability is 0.55.

Greeley [361]

Javier rode his bike for a total of 40 minutes.

Let x be the minutes Javier ride after lunch

Let y be the minutes Javier ride before lunch

The number of minutes he rode after lunch is 4 times the number of minutes he rode before lunch

x = 4 y

The number of minutes he rode after lunch + number of minutes he rode before lunch = 40

x + y = 40

We know x= 4y

4y + y = 40

5y = 40

y = 8

x= 4y so x= 4(8) = 32

Javier ride 32 minutes after lunch

Find the unit rate<br> 180 miles in 4 hours =<br> miles per hour

Andrei [34K]

Answer:

= 45 miles per hour

Step-by-step explanation:

First, we want a unit rate where 1 is in the denominator.

So we divide,

180 miles/ 4 hours both ÷ by 4

= 45 miles/ 1 hour

= 45 miles/ hour

= 45 miles per hour
