Answer:
5 and 1 over 6
Step-by-step explanation:
<u>Simplifying the given:</u>
- Negative 2 and 1 over 6 – negative 7 and 1 over 3 ⇒ <em>translated as</em>:
- - 2 1/6 - (-7 1/3) = ⇒ <em>cancelling negatives and changing mixed fractions to improper fractions</em>
- - 13/6 + 22/3 = ⇒ <em>bringing to same denominator</em>
- - 13/6 + 44/6 = ⇒ calculating the numerator
- 31/6 = ⇒ making mixed fraction
- 5 1/6 ⇒ answer
<u>Correct choice is the last one: </u>5 and 1 over 6

Answer:
£0.8
Step-by-step explanation:
egg = 2.80
Bacon = 2 * 2.40 = 4.80
Baked beans = 2 tins
Amount issued = 10
Change obtained = 80p = 0.8
Let cost per baked beans = x
Hence,
2.80 + 4.80 + 2x = 10 - 0.8
7.60 + 2x = 9.20
2x = 9.20 - 7.60
2x = 1.6
x = 1.6 / 2
x = 0.8
Hence, a tin of baked beans cost £0.8

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Z score is given by:
z = (raw score - mean) / standard deviation
Given mean of 36 minutes and a standard deviation of 3 minutes.
For x = 32:
z = (32 - 36)/3 = -1.33
For x = 37:
z = (37 - 36)/3 = 0.33
P(-1.33 < z < 0.33) = P(z < 0.33) - P(z < -1.33) = 0.6179 - 0.0198 = 0.5981
The probability that a randomly selected customer will have to wait between 32 minutes and 37 minutes is 59.81%
