A drug trial is testing the effectiveness of two drugs. If 80 patients are given Drug A, 10 patients are given Drug B, and 20 patients are given a placebo, what is the probability that a patient will NOT be given a placebo?

Answers

Answer:

The answer is 9/11.

Step-by-step explanation:

To find the answer you'd first add up how many patients you have:

80+10+20 = 110.

Now find out that how many patients are taking a real drug, which is represented by 80+10 = 90.

So, the probability of a patient NOT getting a placebo is 90/110

Simplified would be 9/11

Thus the answer is 9/11....

Find the area of a regular pentagon with an apothem of 6 inches and a side length of 8.7 inches. Round to the nearest tenth.

Answers

The area of the pentagon is 130.5 inches. The area of a pentagon, if you don’t know, is equal to the perimeter of the pentagon times the apothem, all divided by 2. Because one side of the pentagon has a length of 8.7 inches, and all sides of a pentagon have the same length, then the perimeter would be equivalent to 8.7 times 5, which equals a perimeter of 43.5 inches. Now that our perimeter is found, our equation is set (because the apothem is 6 inches, as said in the problem). Now, to solve, we have to multiply the perimeter (43.5 in.) by the apothem (6 in.), which equals 261 inches. Now, all we have to do is divide it by 2, which will give us our answer of 130.5 inches. Bonus: The answer only reaches out to one decimal point, meaning that there is no need to round!

The area of the pentagon is 130.5 sq.inches

What is the area of a pentagon?

Apothem is the line that extends from the pentagon's center to a side and makes a 90° right angle with the side.

The basic formula for calculating the area of a regular pentagon is Area of pentagon = 1/2 p a, where p denotes the pentagon's perimeter and a denotes its apothem.

perimeter = 5 * 8.7 = 43.5

a = 6

area = 1/2 * 43.5 * 6 = 130.5

Therefore, The area of the pentagon is 130.5 sq.inches

What banking service would be the most beneficial for a customer who just obtained a debit card?
0% financing
no ATM fees
$25 yearly fees
no overdraft protection

Answers

The most beneficial banking service for a customer with a new debit card would be no ATM fees, as this would save money on transactions, which is especially important given that banks tend to charge for non-interest income such as ATM and overdraft fees.

For a customer who just obtained a debit card, the most beneficial banking service would be no ATM fees. Debit cards give users the ability to access their funds through an ATM. Considering banks are profit-oriented and look to maximize non-interest income through various fees as described, ATM fees can be a frequent and unnecessary expense. ATM fees average $2.97 per transaction and can quickly accumulate, especially if withdrawals are made at out-of-network ATMs, which add even more to the cost. Therefore, selecting a banking service with no ATM fees would save the cardholder potential costs associated with accessing their money.

No overdraft protection would mean the cardholder could be charged substantial overdraft fees if they were to spend more than the balance in their checking account. Given that these fees can be very high, it's better to either have overdraft protection or manage the account carefully to avoid overdrafting. On the other hand, a $25 yearly fee is a fixed cost and might be worth it if the benefits provided surpass the fee, but it is generally an additional expense that can be avoided with careful account selection. Lastly, 0% financing is typically associated with credit cards rather than debit cards and the quoted 'introductory' rates can be misleading, often coming with hidden fees and high interest rates after the introductory period ends.

which is the graph of the linear equation y = - 1/3x + 5

Answers

Answer:

The second one.

Step-by-step explanation:

The slope of the graph, -1/3, is going down from left to right because it is negative, so it is decreasing. Slope is the rise over run, so because the slope is -1/3 look for lines that go down 1 unit and across 3 at the same time (from one corner of a square to the other). Then, because your y-intercept is a 5, just look for your line to cross the y-axis at 5. And that's it.

The second graph is the graph of the linear equation y = - 1/3x + 5.

What is slope intercept form of line?

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The given linear equation is  y = - 1/3x + 5

We need to select the graph of the equation.

The slope of the line is -1/3

y intercept is 5.

Let us find few points to determine the graph.

if x=0, then y=-1/3(0)+5=5

So (0, 5) is one of the point

if x=1, then y=-1/3(1)+5

=14/3

(1, 14/3)

if x=2, then y=-1/3(2)+5

=13/3

(2, 13/3)

if x=3, then y=-1/3(3)+5

(3, 4) is point.

Now let us check these points which satisfy the graph.

Hence, the second graph is the graph of the linear equation y = - 1/3x + 5.

Answers

The correct answers are:

A. P = 58 and Q = 78

C. P = -78 and Q = -52

D. P = 58 and Q = -78

To determine which values of P and Q result in the equation Px + 52 = Qx - 78 having exactly one solution, we need to ensure that the coefficients of x on both sides are not equal. This means P should not be equal to Q.

The given equation is:

Px + 52 = Qx - 78

First, let's rearrange the terms to isolate x:

Px - Qx = -78 - 52

(P - Q)x = -130

For this equation to have exactly one solution, P - Q must be non-zero. Therefore, P - Q.

Let's evaluate each option:

A. P = 58 and Q = 78

- P - Q = 58 - 78 = -20

- Since -20 is not zero, this pair results in exactly one solution.

B. P = 52 and Q = 52

- P - Q = 52 - 52 = 0

- Since 0 is zero, this pair does not result in exactly one solution.

C. P = -78 and Q = -52

- P - Q = -78 - (-52) = -78 + 52 = -26

- Since -26 is not zero, this pair results in exactly one solution.

D. P = 58 and Q = -78

- P - Q = 58 - (-78) = 58 + 78 = 136

- Since 136 is not zero, this pair results in exactly one solution.

B) How long does it take to rotate 7π radians?
C) The diameter of the Earth is approximately 7920 miles. How far will a point on the equator rotate in 2 hours?
Show all work. Give answers to the nearest hundredth. Include the units in your response.

Answers

Answer:

A)

58/3 = 19.33 hours

B)

84.00 hours

C)

2074.29 miles

Step-by-step explanation:

Under the assumption the earth is a perfect circle, then in a complete rotation ( 24 hours) the earth will rotate through  360 degrees or 2π radians.

A)

In one day or 24 hours the earth rotates through 360 degrees. We are required to determine the duration it takes to rotate through 290 degrees. Let x be the duration it takes the earth to rotate through 290 degrees, then the following proportions hold;

(24/360) = (x/290)

solving for x;

x = (24/360) * 290 = 58/3 = 19.33 hours

B)

In 24 hours the earth rotates through an angle of 2π radians. We are required to determine the duration it will takes the Earth to rotate through 7π radians. Let x be the duration it takes the earth to rotate through 7π radians, then the following proportions hold;

(24/2π radians) = (x/7π radians)

Solving for x;

x = (24/2π radians)*7π radians = 84 hours

C)

If the diameter of the earth is 7920 miles, then in a day or 24 hours a point on the equator will rotate through a distance equal to the circumference of the Earth. Using the formula for the circumference of a circle;

circumference = 2*π*R = π*D

                         = 7920*3.142

                         = 24891.43 miles

Therefore a point on the equator covers a distance of 24891.43 miles in 24 hours. This will imply that the speed of the earth is approximately;

(24891.43miles)/(24 hours) = 1037.14 miles/hr

The distance covered by the point in 2 hours will thus be;

1037.14 * 2 = 2074.29 miles

Blue whale babies are born big. They can weigh as much as 6,000 pounds at birth. They grow for one full year to reach their adult size.2Blue whales live in the ocean. They swim fast, which helps them catch food. Blue whales must eat up to 8,000 pounds of food each day. They eat tiny fish called krill. To eat, the whale opens its mouth and lets the krill swim in. Once the krill are inside, the whale begins to close its mouth. It does not close the mouth the whole way, though. The whale shows its baleen. Baleen are long, strong hairs that act like teeth. The baleen allow the water to flow out. The baleen keep the krill in. The whale can then eat the fish.3Blue whales are named for their color. However, they are not really blue. Although they look blue under the water, they are actually gray. Blue whales prefer to swim alone. Their bellies are yellow.4Since blue whales are mammals, they must breathe air. Blue whales have a blowhole on the tops of their heads. A blowhole is like the nostril in a human nose. It lets blue whales breathe the air in and blow it back out. When whales go underwater, they can close their blowholes. They can open their blowholes when they want, too. 5Because of their size, blue whales cannot be harmed by many other animals.
