Correct answer is: P(x<6) is 0.123 and it is usual.
Solution:-
Given that the time a person takes to decide which shoes to purchase follows normal distribution. Which has mean = 8.21 minutes and standard deviation 1.90
Then probability of individual takes less than 6 minutes is
P(X<6) =
=
= 0.1230
Typically we say an event with a probability less than 5% is unusual.
But here P(X<6) = 0.123 is greater than 5% hence this is usual.

Answer:
10
Step-by-step explanation:
In this problem we need to round off 8.546 to the nearest tens. 8 is in ones place, 5 is in tenths place, 4 is in hundredths place and 6 is in thousandth place.
8 falls between 5 and 10 on the number line. It is less than 5 and more than 10. When it is rounded off to nearest tens it can be given by 10.
To round 8.546 to the nearest tens, the answer is 10.
To round 8.546 to the nearest tens, you need to look at the digit in the ones place, which is 6.
Since 6 is greater than or equal to 5, you round up the tens digit, which is 4.
Therefore, the final answer is 10.

20 grams
Step-by-step explanation:
10 grams is 50%. 50% x 2= 100%. so you do 50/100=10/20, and you will get 2. Apply that to the 10, 10 x 2=20.
would you get from £1
if you spent 77p?
Answers
You would get 23p as change from £1 if you spent 77p.
To find how much change you would get from £1 if you spent 77p, you need to subtract the amount you spent from the total amount you have.
Total amount = £1
Amount spent = 77p
To find the change, we need to convert both amounts to the same unit (pence) before performing the subtraction.
1 pound (£1) is equal to 100 pence, so:
Total amount = 100p
Amount spent = 77p
Now, subtract the amount spent from the total amount to find the change:
Change = Total amount - Amount spent
Change = 100p - 77p
Change = 23p
So, you would get 23p as change from £1 if you spent 77p.
