An aerospace company has submitted bids on two separate federal government defense contracts. The company president believes that there is a 45% probability of winning the first contract. If they win the first contract, the probability of winning the second is 73%. However, if they lose the first contract, the president thinks that the probability of winning the second contract decreases to 46%. A. What is the probability that they win both contracts

Answers

Answer 1

The probability that they win both contracts is 33% if there is a 45% probability of winning the first contract and the probability of winning the second contract after winning the first contract.

What is probability?

Probability is the rate of successful outcomes to the total outcomes of an event.

P(E) = n(E)/n(S)

Where E -event, n(E) - successful/favorable outcomes of event E, and n(S) - total outcomes of the event.

Calculation:

It is given that,

An aerospace company has submitted bids on two separate federal government defense contracts.

The probability of winning the first contract is - 45%

The probability of winning the second contract if they win the first contract is  - 73%

The probability of winning the second contract if they lose the first contact is - 45%

So, the probability that they win both contracts is

= (probability of winning the first contract) × (probability of winning the second contract)

= 0.45 × 0.73

= 0.3285 ≅ 0.33

33%

Therefore, the probability that they win both contracts is 33%.

12. The average bowling score of the 5-member in Regional High School bowling team is 128. If all the members of the team get the same score except for one, who bowls a 160, what is the score of the rest of the players? (A) 32 (B) 96 (C) 120 (D) 144​

Answers

Answer:

C

Step-by-step explanation:

The average is the total of the scores divided by 5.  

128 x 5 Gives us the total scores of 640.  I know that one bowler had a score of 160.  I will subtract that from the total of 640.  640-160 = 480.  Since the 4 bowlers left, all had the same score, I will divide 480 by 4 to get 120

A prism with a heart-shaped base is sliced parallel to the base. What shape is formed?

Answers

The shape formed, when a prism with a heart-shaped base is sliced parallel to the base, will be congruent to its base. Hence, it will also be heart-shaped.

A prism is a polyhedron made up of n parallelogram faces that connect the n-sided polygon base, the second base, which is a translated duplicate of the first base, and the n faces. The bases are translated into all cross-sections that are parallel to them.

In the question, we are informed that a prism with a heart-shaped base is sliced parallel to the base.

We are asked what shape is formed.

From the above discussion, we know that the bases are translated into all cross-sections that are parallel to them, that is, all cross-sections parallel to the base, will be congruent to the base.

Thus, the shape formed, when a prism with a heart-shaped base is sliced parallel to the base, will be congruent to its base. Hence, it will also be heart-shaped.

Answers

The area of the sector in radians is calculated as: B. 8π units squared.

What is the Area of a Shaded Sector?

The area of a sector where the central angle of the sector that is shaded in a circle is given in radians is calculated using the formula that is expressed as:

Area of sector = (1/2) × r²θ; where we have:

θ = the angle subtended at the center/central angle measure in radians

r = the radius of the circle

Given the following:

The shaded area is half of the circle. Its measure would be 180 degrees which when expressed in radians would be π.

Central angle measure in radians (θ) = π

Radius (r) = 4 units

Plug in the values into the area of sector formula

Area of sector = (1/2) × r²θ = (1/2) × (4²)(π)

Area of sector = (1/2) × (16)(π)

Area of sector = (1 × 16 × π)(2)

Area of sector = (16π)(2)

The original cylinder has radius r and height h.

V = πr²h

Its volume is 30 in.³, so

πr²h = 30 in.³

The new cylinder has radius (1/2)r and height 2h.

Its volume is

V = π(r/2)²(2h)

Circadian rhythms are biological processes that oscillate with a period of approximately 24 hours. That is, a circadian rhythm is an internal daily biological clock. Blood pressure appears to follow such a rhythm. For a certain individual the average resting blood pressure varies from a maximum of 100 mmHg at 2:00 P.M. to a minimum of 80 mmHg at 2:00 A.M.
Find a sine function of the form f(t) = a sin(ω(t − c)) + b
that models the blood pressure at time t, measured in hours from midnight.

Answers

The equation becomes of the pressure is   P = 90 + 10 sin(π/36(t +4 ))

By observation the sine function should be of form P=  90 + 10 sin(ω(t − c)) as it oscillates about 90 and with a factor of 10. Let time be represented by the variable t in hours from 12.00 AM.

At 2:00 P.M. that is t= 14 hours the pressure is 100 mmHg

Substituting it in the equation we get,

100 = 90 + 10 sin(ω(t − c))

10 = 10  sin(ω(14 − c))

1 = sin(ω(14 − c))

ω(14 − c) = π/2                           -1)

At 2:00 A.M. that is t= 2 hours the pressure is 80 mmHg

80 = 90 + 10 sin(ω(t − c))

-10 = 10 sin(ω(2 − c))

3π/2 = ω(2 − c)                           -2)

dividing 2) with 1) we get

3 = (14 − c) /(2 − c)  

6 - 3c = 14 - c

2c = -8

c = - 4

Substituting the value of c in 1) we get,

ω(14 − (-4)) = π/2

ω18 =  π/2

ω = π/36

Thus the equation becomes  P = 90 + 10 sin(π/36(t +4 ))

If 5/6 is 180, what is 1/6?
(please explain as well)

Answers

Divide your numerator by your denominator to get your answer

Answer: 36

Step-by-step explanation:

If 5/6 = 180

lets find what 1/6 equals

To do this lets divide 180 by 5 to find 1/6

[tex]\frac{180}{5} =36[/tex]

Therefore, 1/6 = 36


We know 180/5 will give us the answer because 180 is already 5/6 of the total; dividing by 5 will give us 1/6 of the total. Ex: if we had 4/6 of the total, we would divide by 4 to find 1/6.

Anyways, we can check our answer by doing:

36*5 = 216 then taking 5/6 of 216, which should equal 180

[tex]216*\frac{5}{6} =180[/tex]

Therefore, we know 36 is the correct answer

Perpendicular = 12 feet

Hypotenuse = 20 feet

Base = ?

According to Pythagoras Theorem

(Hypotenuse)² =  (Perpendicular)²+(Base)²

(20)² = (12)² + (Base)²

Assuming that your classmate and Tim agree that his van is in average condition, what price should she offer him? What is the price you would consider fair? Explain.2. The sample contains a Eurovan with 81,718 thousand miles on it. Assuming that the price given accurately reflects the condition of the car, do you think this van is likely to be in below-average, average, or above average condition, given its mileage. Explain your answer. Let us imagine another allele G that is also present at a 60% frequency in a population over many generations. The only other locus at the allele, W is present at a 40% frequency. We observe that 1% of GG individuals die each generation due to a genetic disease. This makes it somewhat surprising that the G allele has stayed at such high frequency in the population. We suspect that heterozygote advantage is keeping the G allele around. How large of an advantage would GW heterozygotes have to have over WW homozygotes to explain the above data? (To let Canvas detect your answer correctly, answer as a fraction, so a 1% Let's use what we know about mutation-selection balance to answer a more challenging question. Imagine we have an allele L that is present at 60% of the population, and after further research find that L has been present at this frequency for many generations. We study further and find that the L allele is recessive to V. LL individuals have a minor genetic disease that causes 1 in 1000 LL individuals to be infertile each generation, while W or VL individuals have a normal phenotype. Valleles mutate into L alleles with a fixed chance per allele per generation which we will signify with mu. In contrast, L alleles mutate to V alleles so rarely that we can ignore L-> V mutations. What mutation rate mu for V -> L mutations would be required to cause the equilibrium frequency of Lin the population to be 60%? In human genomes, the per nucleotide mutation rate is estimated to be about 2.5 x 10^-8. Let us consider a recessive lethal genetic disease caused by a single point mutation. We will name the allele produced by this point mutation L, and the wild-type allele W. Let us further assume that the disease phenotype expressed by LL individuals always kills those who have it before they reproduce. What would you predict the equilibrium frequency of the allele L be in the population after many generations? (You may assume Hardy-Weinberg equilibrium except for mutation and selection, and you may assume as an approximations that back-mutations from L to wild-type are rare enough to be ignored). You are studying an allele A that governs parasite resistance in a large population of rabbits. You observe that different combinations of A and a produce phenotypes that have different fitnesses due to differences in parasite resistance. The fitness of AA is 0.38, the fitness of Aa is 0.38, while the fitness of aa is 0.24. The A allele starts at a frequency of 0.67. Assuming Hardy-Weinberg equilibrium except for differences in selection, what will the frequency of A be in the next generation? 30 points A t - shirt company sells shirts in 4 different sizes (S, M, L and XL) that are available in blue, red, white, black or gray.

Suppose you have an injection molding machine for plastic products costing $220,000, and for whatever reason, you decide to depreciate it using MACRS-ADS. It is considered to be in a 7-year class and yet is depreciated over 11 years if MACRS-ADS is elected. Determine the depreciation percentages to two places after the decimal (e.g., 9.62 percent) and the depreciation allowance for each year. Hint: Don't forget the half-year convention!
