Answer:
Monthly fare of employer = $ 10
Fare for swiping = $ 0.15
No. of times swiped = 40
Total cost spent = $10 + $ 0.15
= $ 10.15
Total cost of swipe = $ 0.15 × 40
= $ 0.60
Answer:
5 and 6
Step-by-step explanation:
let the 2 consecutive integers be n and n + 1 , then
3(n + 1) = 5n - 7
3n + 3 = 5n - 7 ( subtract 3n from both sides )
3 = 2n - 7 ( add 7 to both sides )
10 = 2n ( divide both sides by 2 )
5 = n and n + 1 = 5 + 1 = 6
the 2 consecutive integers are 5 and 6
Probability that it will rain on the first day and be clear (not rain ) on the next two days is 0.1719 .
<u>Step-by-step explanation:</u>
We are given that there is a 23% chance it will rain on any day, we need to find what is the probability that it will rain on the first day and be clear (not rain ) on the next two days . Let's do it step by step:
Probability for first day is to rain i.e.
.
Probability for second day is to not rain i.e.
.
Probability for third day is to not rain i.e.
.
Now, Probability for occurrence of these 3 events simultaneously is :
⇒ ![(0.23)(0.77)(0.77)](https://tex.z-dn.net/?f=%280.23%29%280.77%29%280.77%29)
⇒ ![(0.23)(0.5929)](https://tex.z-dn.net/?f=%280.23%29%280.5929%29)
⇒ ![0.1719](https://tex.z-dn.net/?f=0.1719)
∴ Probability that it will rain on the first day and be clear (not rain ) on the next two days is 0.1719 .
Answer:
See below.
Step-by-step explanation:
Total consumed = 1/4 + 1/5
= 5/20 + 4/20
= 9/20 of the salad they eat
1 - 9/20
= 11/20 of the salad is left
10/20 is half so more than half the salad is left
Answer:
Step-by-step explanation:
Vertically opposite angles are equal
8x + 2 = 7x + 11
Subtract 2 from both sides
8x = 7x + 11 - 2
8x = 7x + 9
Subtract 7x from both sides
8x - 7x = 9
x = 9
