Answer:
$836.8
Step-by-step explanation:
Average price = mean = $965
Standard deviation, = $100
Given that distribution is approximately normal ;
The least expensive 10% of the laptops :
We Obtain the Zscore that corresponds to P(Z ≤ 0.1) ; this means the least 10% of the laptops ;
From, a normal probability distribution table ;
P(Z ≤ 0.1) = - 1.282
We substitute this into the Zscore formula :
Zscore = (x - mean ) / standard deviation
x = price
-1.282 = (x - 965) / 100
-128.2 = (x - 965)
x = - 128.2 + 965
x = $836.8
Hence, price is $836.8

Multiplication is helps to add a number multiple times. The meaning of 6 x 5 is 6 + 6 + 6 + 6 + 6.
<h3>What is multiplication?</h3>
Multiplication tells us the number of times a number is been added to itself. For example, 3 x 2 = 3 + 3 = 2 + 2 + 2
Given to us
5 x 6
As we have already discussed that multiplication is the number of times a number is been added to itself. therefore,
5 x 6 = 5 + 5 + 5 + 5 + 5 + 5 = 6 + 6 + 6 + 6 + 6
Hence, the meaning of 6 x 5 is 6 + 6 + 6 + 6 + 6.
