(750-182.9) divided by 5.35 = Number of pizzas left to sell = 106
106 = answer
Hope this helped! If it did, please give brainliest! It would help a lot :D

Answer:
12
Step-by-step explanation:
I assume we are solving for x see attachment.
To calculate for the standard deviation given the
probability, we use the formula:
s = sqrt (n p q)
where s is standard deviation, n is number of samples = 11,
p is probability of success = 0.7, q = 1 – p = 0.30
s = sqrt (11 * 0.7 * 0.3)
<span>s = 1.52</span>
