A certain restaurant always overbooks. If possible. At 7:00 pm the restaurant can seat 50 parties, but takes reservations for 53. If the probability of a party not showing up is 0.04, assuming independence, what is the probability that the restaurant can coommodate all the customers who do show up? You must show all of your work including the correct formulas for calculation to receive full credit of this answer
Answer:
The probability that the restaurant can accommodate all the customers who do show up is 0.3564.
Step-by-step explanation:
The information provided are:
At 7:00 pm the restaurant can seat 50 parties, but takes reservations for 53. If the probability of a party not showing up is 0.04. Assuming independence.Let X denote the number of parties that showed up.
The random variable X follows a Binomial distribution with parameters n = 53 and p = 0.96.
As there are only 50 sets available, the restaurant can accommodate all the customers who do show up if and only if 50 or less customers showed up.
Compute the probability that the restaurant can accommodate all the customers who do show up as follows:
[tex]P(X\leq 50)=1-P(X>50)\\=1-P(X=51)-P(X=52)-P(X=53)\\=1-[{53\choose 51}(0.96)^{51}(0.04)^{53-51}]-[{53\choose 52}(0.96)^{52}(0.04)^{53-52}]\\-[{53\choose 53}(0.96)^{53}(0.04)^{53-53}]\\=1-0.27492-0.25377-0.11491\\=0.3564[/tex]
Thus, the probability that the restaurant can accommodate all the customers who do show up is 0.3564.

B. 21
C. 24
D. 42
Answer:
A. 11
Step-by-step explanation:
Since the measure of (4x- 6) is 90°, you would first solve the equation for x
4x - 6 = 90
4x - 6 + 6 = 90 + 6
4x = 96
x = 24°
-------------------------------------------------------------------------------------
Since (4x - 6) was a right angle, (x + 6y) is also a right angle. Therefore, you would do:
x + 6y = 90
24 + 6y = 90
24 + 6y - 24 = 90 -24
6y = 66
y = 11°

one possible combination of homeroom groups is 18 groups of 10 students and 5 groups of 12 students. which equation uses the x = 10 students and y=12 students, combination to represent the situation in point- slope form? is the answer y-18 =-5/6 (× - 5) ,y- 5 = - 5/6 (× -18) ,y +5 =-5/6 (× +18) or y+18= -5/6 (× +5)
Answer: y - 5 = -5/6 (x - 18)
Step-by-step explanation:
The point-slope form of a linear equation is written using the slope of the line and one point in the line. From part A, the slope of the line representing this situation is m = -5/6.
Since x represents the number of 10-student groups and y represents the number of 12-student groups, the combination of 18 groups of 10 students and 5 groups of 12 students is represented by the point (18,5).

Step-by-step explanation:
For concave pentagon ABCDE, find the measure of the reflex angle at vertex E (in degrees) if m∠A = m∠D = x°, m∠B = m∠C = (4x)°, and the measure of the reflex angle at vertex E is (8x)°.
Answer:
Step-by-step explanation:
First we need to calculate the sum of interior angle of the pentagon. The sum of interior angle of any polygon is expressed as S = (n-2)180
Given n = 5
S = (5-2)180
S = 3*180
S = 540°
Hence the measure of interior angle of the pentagon is 540°. The sum of all the interior angles will give us;
<A+<B+<C+<D+<E = 540
Given m∠A = m∠D = x°, m∠B = m∠C = (4x)° and the measure of reflex angle at E is (8x)°. If the reflex angle at E is (8x)°, the interior angle at E will be (360-8x)°
Substituting the given values into the formula to get x;
x+4x+4x+x+360-8x = 540
10x-8x = 540-360
2x = 180
x = 180/2
x = 90°
To find the measure of the reflex angle at vertex E, we will substitute x = 90 into the vertex E = (8x)°.
vertex E = 8(90)
vertex E = 720°

Professor Cramer determines a final grade based on attendance, two papers, three major tests, and a final exam. Each of these activities has a total of 100 possible points. However, the activities carry different weights. Attendance is worth 3%, each paper is worth 9%, each test is worth 17%, and the final is worth 28%. (a) What is the average for a student with 81 on attendance, 90 on the first paper, 92 on the second paper, 86 on test 1, 71 on test 2, 93 on test 3, and 62 on the final exam
Answer:
78.67
Step-by-step explanation:
The computation of the average for a student is shown below:
= Different Weights × different activities
= (3% × 81) + (9% × 90) + (9% × 92) + (17% × 86) + (17% × 71) + (17% × 93) + (28% × 62)
= 2.43 + 8.1 + 8.28 + 14.62 + 12.07 + 15.81 + 17.36
= 78.67
Hence, the average of the student is 78.67

To earn a fitness reward, your average heart rate while walking must be between 80 and 89 beats per minute, inclusive. Suppose you recorded 85, 81, and 87 beats per minute on your first three recordings. What are the possible heart rates you can have on the fourth and final recording in order to earn a fitness reward?
Answer:
Between 67 and 103 beats per minute
Step-by-step explanation:
The minimum would be 80. That means that the minimum sum would have to be 320 among the four numbers.
85+81+87=253
320-253=67 so 67 will be the minimum
now, we should see the maximum. It will be 89 so the sum of the four numbers cannot be anymore than 89*4 which is 356
So, 356-253=103

A. between 67 and 103 beats per minute inclusive
Step-by-step explanation:
What I did was I just started from the top and tried out the mean with 69 and saw that that was 80, so that was right. Then I tried 103, and that was 89, so that's obviously the max.

Answer:
[tex]\sin(\theta)=-\sqrt5/5\text{ and } \csc(\theta)=-\sqrt5\\\cos(\theta)=2\sqrt5/5\text{ and } \sec(\theta)=\sqrt5/2\\\tan(\theta)=-1/2\text{ and } \cot(\theta)=-2[/tex]
Step-by-step explanation:
First, let's determine which quadrant our angle θ lies in.
Remember ASTC, where:
Everything is positive in QI,
Only sine (and cosecant) is positive in QII,
Only tangent (and cotangent) is positive in QIII,
And only cosine (and secant) is positive in QIV.
Since our tangent is negative, and our cosine is positive, this means that our θ must be in QIV.
In QIV, sine is negative, tangent is negative, and cosine is positive.
With that, let's figure out the remaining trig ratios.
We know that:
[tex]\tan(\theta)=-1/2[/tex]
Remember that tangent is the ratio of the opposite side to the adjacent side.
Let's figure out our hypotenuse using the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
Substitute 1 for a and 2 for b (we can ignore the negative since we're squaring anyways). This yields:
[tex](1)^2+(2)^2=c^2[/tex]
Square:
[tex]1+4=c^2[/tex]
Add:
[tex]c^2=5[/tex]
Take the square root:
[tex]c=\sqrt{5}[/tex]
So, our square root is √5.
So, our three sides are: Opposite=1, Adjacent=2, and Hypotenuse=√5.
Sine and Cosecant:
Remember that:
[tex]\sin(\theta)=opp/hyp[/tex]
Substitute 1 for the opposite and √5 for the hypotenuse. This yields:
[tex]\sin(\theta)=1/\sqrt5[/tex]
Rationalize:
[tex]\sin(\theta)=\sqrt5/5[/tex]
And since our angle is in QIV, we add a negative:
[tex]\sin(\theta)=-\sqrt5/5[/tex]
Cosecant is simply the reciprocal of sine. So:
[tex]\csc(\theta)=-\sqrt5[/tex]
Cosine and Secant:
Remember that:
[tex]\cos(\theta)=adj/hyp[/tex]
Substitute 2 for the adjacent and √5 for the hypotenuse. This yields:
[tex]\cos(\theta)=2/\sqrt5[/tex]
Rationalize:
[tex]\cos(\theta)=2\sqrt5/5[/tex]
Since our angle is in QIV, cosine stays positive.
Secant is the reciprocal of cosine. So:
[tex]\sec(\theta)=\sqrt5/2[/tex]
Tangent and Cotangent:
We were given that:
[tex]\tan(\theta)=-1/2[/tex]
To find cotangent, flip:
[tex]\cot(\theta)=-2[/tex]
And we're done!

Suppose an employee is suspected of having used an illegal drug and is given two tests that operate independently of each other. Test A has probability 0.91 of being positive if the illegal drug has been used. Test B has probability 0.88 of being positive if the illegal drug has been used. The company requires that an employee, Al Capone, take and pass both tests to keep his job. Assume that Al has, in fact, been using the illegal drug. What is the probability that neither test is positive (and thus Al gets to keep his job)
Answer:
The probability that neither test is positive
P(A⁻ ∩ B⁻ ) = 0.0108
Step-by-step explanation:
Step(i) :-
Given the two tests are independently
Test A has probability 0.91 of being positive if the illegal drug has been used
P(A) = 0.91
Test B has probability 0.88 of being positive if the illegal drug has been used
P(B) = 0.88
If events are independently then ,
[tex]P(A n B) = P(A) P(B)[/tex]
Step(ii):-
The probability that neither test is positive (and thus Al gets to keep his job)
[tex]P(A^{-} n B^{-} ) = P(A^{-} ) P(B^{-} )[/tex]
P(A⁻ ∩ B⁻ ) = P(A⁻ ) P(B⁻ )
= ( 1- P(A) ) ( 1 - P(B))
= (1 - 0.91 ) ( 1 - 0.88 )
= (0.09) (0.12)
= 0.0108
The probability that neither test is positive
P(A⁻ ∩ B⁻ ) = 0.0108

The National Center for Health Statistics, housed within the U.S. Centers for Disease Control and Prevention (CDC), tracks the number of adults in the United States who have health insurance. According to this agency, the uninsured rates for Americans in 2018 are as follows: 5.1% of those under the age of 18, 12.4% of those ages 18–64, and 1.1% of those 65 and older do not have health insurance (CDC website). Approximately 22.8% of Americans are under age 18, and 61.4% of Americans are ages 18–64.a. What is the probability that a randomly selected person in the United States is 65 or older?b. Given that the person is an uninsured American, what is the probability that the person is 65 or older?
Answer:
a. 0.158
b. 0.01942
Step-by-step explanation:
For part a we define probability that the randomly selected person is if 65 years or more than that
a.
Probability of under age = 22.8% = 0.228
Probability of those from age 18 to 64 = 61.4% = 0.614
1-0.228-0.614
= 0.158
b.
P(uninsured) = p(those not up to 18) * p(those uninsured or under 18) + p(those age 18-64) * p(uninsured or under 18) + p(being 64plus) x P(uninsured or 64 plus)
= 0.228 x 0.051 + 0.614 x 0.124 + 0.158 x 0.011
= 0.011628 + 0.076136 + 0.001738
=0.089502
P(65 of older|uninsured) = p(64+) x P(uninsured or 64 plus)
= 0.157 x 0.011/0.089502
= 0.001738/0.089502
= 0.01942
a. The probability that a randomly selected person in the United States is 65 or older is 0.158
b. In the case when the person is an uninsured American so the probability is 0.01942
Calculation of probabilities:a.
Since
Probability of under age = 22.8% = 0.228
And,
Probability of those from age 18 to 64 = 61.4% = 0.614
So, the probabilities of 65 or older is
= 1 - 0.228-0.614
= 0.158
b.
Now
P(uninsured) = p(those not up to 18) × p(those uninsured or under 18) + p(those age 18-64) × p(uninsured or under 18) + p(being 64plus) × P(uninsured or 64 plus)
= 0.228 × 0.051 + 0.614 × 0.124 + 0.158 × 0.011
= 0.011628 + 0.076136 + 0.001738
=0.089502
So,
P(65 of older|uninsured) = p(64+) × P(uninsured or 64 plus)
= 0.157 × 0.011 ÷ 0.089502
= 0.001738 ÷ 0.089502
= 0.01942
