The probability that a customer orders coffee or pie is 21/26 or 0.8
<u>Step-by-step explanation:</u>
It is given that,
26 customers are eating dinner at a local diner.
The total number of customers = 26
Of the 26 customers,
- 20 order coffee
- 8 order pie and
- 7 order coffee and pie.
<u>To find the probability that a customer orders coffee or pie :</u>
The formula used is P(A or B) = P(A) + P(B) - P(A∪B)
Here,
- The event A is ordering coffee.
- The event B is ordering pies.
P(coffee) = No.of customers order coffee / Total customers
⇒ 20 / 26
P (pie) = No.of customers order pie / Total customers
⇒ 8 / 26
P (coffee and pie) = No.of customers order both / Total customers
⇒ 7 / 26
P (coffee or pie) = P(coffee) + P(pie) - P (coffee and pie)
⇒ 20/26 + 8/26 - 7/26
⇒ 21/26
⇒ 0.8
∴ The probability that a customer orders coffee or pie is 21/26 or 0.8
2.109
2.6
2.1062
2.16
Look at the tenths place first. All of the numbers have 1 besides 2.6 in the tenths place, so we know that 2.6 will go last because it is the greatest.
Now look at the hundredths place. 2.109 and 2.1062 both have 0 while 2.16 has 6 in the hundredths place, so 2.16 will go third to last.
Now look at the thousandths place. 2.1062 has 6 while 2.109 has 9, and 6 is less than 9. That means 2.1062 is less than 2.109 so 2.1062 will be first and 2.109 will be second.
The answer is 2.1062, 2.109, 2.16, 2.6.
Lisa had $32.4 in her savings before going to the bakery
Step-by-step explanation:
Let's assume that the amount of money Lisa had: x
Amount of money Lisa spent: $14.20
Amount of money Lisa brings home: more than $2.00 or >$2
<em>To find the amount of money Lisa had before, add the amount that Lisa spent and the amount she had left approximately and multiply it by two since she only brought half of her savings</em>
Total amount Lisa had > 2 (Amount of money Lisa spent + Amount of money Lisa brings home)
x > 2 (14.2 + 2)
x > 16.2 x 2
x > 32.4
The total amount that Lisa had in her savings before going to the bakery is more than $32.4.
