Answer: e. .0950

Step-by-step explanation:

Let X be the number of people that can be cure from disease.

Since each people independently has a 40% chance of contracting the disease.

So , X\sim Binomial(n=15,p=0.40)

A hospital has the capacity to handle at most 8 cases of the disease.

Binomial distribution formula : P(X=x)= ^nC_xp^x(1-p)^{n-x}

Then , the probability that the hospital’s capacity will be exceeded

P(X>8)=1-P(X\leq8)\\\\=1-0.905\ \ [\text{Using Binomial distribution table for n=15 , x=8 and p=0.4.}]

=0.095

Hence, the probability that the hospital’s capacity will be exceeded is e. .0950.

Thus , the correct option is e. .0950.

Advocard [28]

Answer:

$226,300

Step-by-step explanation:

Given Allowance for Doubtful Accounts is estimated as $205,000 and Allowance for Doubtful Accounts has a debit balance of $21,300

#The  amount of the adjusting entry for uncollectible accounts is calculated as below:

Adjustment \ Cost=Allowance\ Doubtful\ Accounts +Doubtful \ Accounts \ Debit \ Balance\\\\=205000+21300\\\\\$226,300

Hence,  the amount of the adjusting entry for uncollectible accounts is $226,300

The sum of two consecutive integers is 329
saw5 [17]
A = first integer
a + 1 = 2nd integer

a + a + 1 = 329
2a + 1 = 329
2a = 329 - 1
2a = 328
a = 164

a + 1 = 164 + 1 = 165

so ur 2 consecutive integers are : 164 and 165

Write an inequality that represents the situation. Jon can do less than 25 sit-ups on an exercise ball. How many sit-ups might J
o-na [289]

The inequality is x<25, when Jon cam do less than 25 sit-ups on an exercise ball.

Given that,

Jon can do less than 25 sit-ups on an exercise ball.

We have to find an inequity to illustrate the circumstance.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

The inequality is

Take the exercise balls as x

x<25

Therefore, the inequality is x<25, when Jon cam do less than 25 sit-ups on an exercise ball.
