I personally think Natalie's bill is the greatest because $24.25 × 10 =x
Answer:
Step-by-step explanation:
We would assume a binomial distribution for the handedness of the population. Let x be a random variable representing the type of handedness in the population. The probability of success, p is that a randomly chosen person is left handed only. Then probability of failure is that a chosen person is not left handed only(right handed only or both).
p = 12/100 = 0.12
number of success, x = 20
n = 200
the probability that there are at least 20 left-handers is expressed as P(x ≥ 20)
From the binomial probability calculator,
P(x ≥ 20) = 0.84

▹ Answer
<em>Her dad's swimsuit costs $65.</em>
▹ Step-by-Step Explanation
Since Monica's swimsuit is $35, we will subtract that from the total amount spent, $170.
$170 - $35 = $135
Since Monica's mom's swimsuit costs 2x Monica's we will multiply 35 * 2:
$35* 2 = $70
We will now add Monica's cost and her moms' cost:
$35 + $70 = $105
To find Monica's dads' cost, we will subtract 105 from 170:
$170 - $105 = $65
Her dad's swimsuit costs $65.
Hope this helps!
