If we ask 500 individuals whether they have credit card and if we consider the probability of people having a credit card being normally distributed, then we assume that, considering 30% do not have a credit card, everyone who is within 1SD of the mean will have a credit card, while the remaining ~15% on either tail of the distribution do not.
It’s A

Assuming that each loaf of brea weighs one pound, the baker would have 8 1/2 pound loaves of bread.
Answer:
The sum =105
Step-by-step explanation:
It is given that, finite sequence 3, 7, 11, ..., 27.
<u>Points to remember</u>
1). For a finite sequence sum of n term is given by
Sum = n/2[first term + last term]
2). nth term of of an AP
tₙ = a + (n - 1)d
Where a - First term
d - common difference
<u>To find the number of terms in the given sequence</u>
Here a = 3 and d = 7 - 3 = 4
tₙ = a + (n - 1)d
27 = 3 + (n - 1)*4
4(n -1) = 27 - 3 = 24
n - 1 = 24/4 = 6
n = 6 +1 =7
<u>To find the sum</u>
Sum = n/2[first term + last term]
= 7/2[3 + 27]
= 7/2[30] = 7 * 15
= 105

The value of 
= 
or, 
</h2>
Step-by-step explanation:
We have,
To find, = ?
∴ 1\dfrac{2}{3}-(-5\dfrac{2}{5}) +000000
