C.

D.
51%

Answers

Answer: The correct answer is B) 21%

Step-by-step explanation:

This is a binomial model probability problem. We need to find the probability of 6 out of 10 new births at a hospital being boys. The information we need is the number of trials observed, the number of successes and the percentage chance you have of any birth being a boy. The number of trials are 10, with the number of successes being 6 (the number of trials we want to be boys) It states that 51% or 0.51 of all births in the US are boys so we can use this value to determine our answer using our binomial model formula. After simplifying we get our answer of 21% I hope this has been of use to you :)

Have a wonderful rest of your day!

The probability that 6 out of 10 births at a local hospital are boys is 21%, so option B is correct.

What is probability?

The ratio of good outcomes to all possible outcomes of an event is known as probability. A lot of successful results for an experimental with 'n' results can be represented by the symbol x.

Given data:

In the U.S., 51% of all births are boys, and 49% are girls

Calculate the probability by the formula given below,

[tex]P(x) = [n! / {x!(n-x)!}]P^xQ^{n-x}[/tex]

Here x = 6 and n = 10, put the values,

P(x) = [10! / {6!(10-6)!}] × 51⁶ × 49⁽¹⁰⁻⁶⁾

P(x) = [10! / {6!4!}] × 0.51⁶ × 0.49⁴

P(x) = 210 × 0.0176 × 0.0577

P(x) = 0.21

P(x) = 21 %

Therefore, the probability that 6 out of 10 births at a local hospital are boys is 21%.

10. Peter had a policy with a $250 deductible which paid 80% of his covered charges less deductible. He had medical expenses of $18,240.00. What is the insurance company's payment?
O $14,392
O $14,300
O $250
O $15,000

Answers

Answer:

$14392

Step-by-step explanation:

The insurance company's payment is $14392. which is the correct answer would be an option (A).

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

The required insurance company's payment is the difference between 80% of medical expenses and 80% of the deductible amount.

According to the given question, the required solution would be as:

The insurance company's payment = 80% of $18,240.00 - 80% of $250

The insurance company's payment = (80/100)18,240.00 - (80/100)250

The insurance company's payment = (0.80)18,240.00 - (0.80)250

The insurance company's payment = 14592 - 200

Apply the subtraction operation,

The insurance company's payment = $14392

Therefore, the insurance company's payment is $14392. which is the correct answer would be an option (A).

Answer:

AE = CE = 23; BE = DE = 20

Step-by-step explanation:

Put the values of the variables in their place and do the arithmetic.

AE = 2u+5 = 2(9) +5 = 23

BE = 6v-1 = 6(3.5) -1 = 20

CE = 3u-4 = 3(9) -4 = 23

DE = 8v-8 = 8(3.5) -8 = 20

Matt paid $450 in interest on a 15 month note for
$5600. Find the rate of interest paid.

Answers

Answer:

The rate is 6.43%

Step-by-step explanation:

Given

[tex]I = 450[/tex] --Interest

[tex]P = 5600[/tex] -- Principal

[tex]T= 15\ months[/tex] --Time

Required

Determine the rate

Using simple interest formula:

[tex]I = PRT[/tex]

Make R the subject

[tex]R = \frac{I}{PT}[/tex]

Convert time to years

[tex]T= 15\ months[/tex]

[tex]T =\frac{15}{12}\ years[/tex]

[tex]T =1.25\ years[/tex]

Substitute values for I, P and T

[tex]R = \frac{450}{5600*1.25}[/tex]

[tex]R = \frac{450}{7000}[/tex]

[tex]R = 0.0643[/tex]

Convert to percentage

[tex]R = 0.0643*100\%[/tex]

[tex]R = 6.43\%[/tex]

Julio tested the point (4, –2) to see whether it is a solution to this system of equations.

–3x – 2y = –8,
y = 2x – 5

His work is shown below.

Negative 3 (4) minus 2 (negative 2) = negative 8. Negative 12 + 4 = negative 8. Negative 8 = negative 8. Therefore, (4, negative 2) is a solution to the system.

Did Julio verify the solution?
No. He substituted 4 and –2 for the wrong variables.
No. He did not check the point in the second equation.
No. He simplified the equation incorrectly.
Yes. He verified that (4, –2) is a solution to the system of equations.

Answer:

90.3%

Step-by-step explanation:

I think you have a typo. I'm pretty sure you meant mean score. To find the mean, we add up all the values and divide by the number of values. Let's add 92, 89, and 90. That gets us 271. Now, let's divide 271 by 3. That gets us 90.3. That means Jesse's mean score is 90.3%.
