In any year, there is a 0.99 percent probability that at least one person will pass away from prostate cancer.

Given that,

Considering mortality rate that 25 out of every 100 American men die from prostate cancer each year.

Prostate cancer has been constant for decades

p= 25/100 = 0.25 men .

To find : The probability that at least 1 out of 100 men will die in year

Let x be number of persons who die from prostate cancer

in a given year .

Then , X ~Binomial ( n = 100 , P = 0 :25 ) .

P ( x\(\geq\)1 ] = 1 - P[ x < 1]

             =  1 - nCx px(1-p)n-x

             =  1 - 100C0 (0.25)^0(1-0.25)^100

             = 1 - 0.00003207

             =0.99996793 ≈0.99

P ( x\(\geq\)1 ]= 0.99

Therefore, prostate cancer deaths are expected to claim at least one life in a given year with a 0.99 chance.

The best way to analyze their data for significance is to Conduct a two-way variable analysis.

As we can see, there is a 2x3 factorial design. Thus, we know that there will be a two level or two way analysis of variables, which is referred to as two way variables analysis. Factorial design is a research method that allows for the inquiry of a main and interaction effects of two or more independent variables on one or more outcome variables (s).

It has been argued that factorial designs represent the true beginning of modern behavioral research and have resulted in a significant paradigm shift in how social scientists conceptualize their research questions and produce objective results (Kerlinger & Lee, 2000).

Factorial design is an experimental methodology that goes beyond standard single-variable experimentation. Previously, social scientists were fixated on single independent variable experiments, foreshadowing the significance of extraneous variables that can attenuate or diminish research findings.

We want to find the height of the clock tower, which is CE. We have the angle of elevation ACD, which is 19 degrees, and the distance AB, which is 100 m. We can use tangent to find CE:

tan(ACD) = CE / AB

tan(19) = CE / 100

CE = 100 * tan(19)

CE ≈ 34.5 m (rounded to 1 decimal place)

Therefore, the height of the clock tower is approximately 34.5 m.

Step-by-step explanation:

The monthly payment to pay off a $3800 balance on a credit card with a 16% APR in 1 year is $316.67. When the card is paid off, the total amount paid since January will be $3,800, with 0% of the payment being interest.

To calculate monthly payments, we need to determine the number of months required to pay off the card. Since the goal is to pay off the balance in 1 year, or 12 months, the monthly payment can be calculated by dividing the balance by the number of months. In this case, the monthly payment would be $316.67 ($3800/12).

To calculate the total amount paid since January, we multiply the monthly payment by the number of months. In this case, the total amount paid would be $3,800, as the balance is paid off in full.

To determine the percentage of the total payment that is interest, we need to calculate the total interest paid. This can be done by subtracting the initial balance from the total amount paid. In this case, the total interest paid would be $0 since the balance is paid off completely. Therefore, the percentage of the total payment that is interest is 0%.

In summary, the monthly payment to pay off a $3800 balance on a credit card with a 16% APR in 1 year is $316.67. When the card is paid off, the total amount paid since January will be $3,800, with 0% of the payment being interest.

The probability of drawing 4 cards of the same suit and 1 card of a different suit from a standard deck of 52 cards can be calculated as follows:

The probability is (13/52) * (12/51) * (11/50) * (10/49) * (39/48), which simplifies to (11/204) ≈ 0.0539.

There are 13 cards of each suit in a standard deck (clubs, diamonds, hearts, and spades). To calculate the probability, we consider the following steps:

Selecting the first card: There are 52 cards in the deck, and we want to choose 1 card of any suit. So, the probability of selecting any card is 52/52, which simplifies to 1/1.

Selecting the second card: After selecting one card, there are now 51 cards remaining in the deck. We want to choose a card of the same suit as the first card. There are 12 remaining cards of the same suit, so the probability of selecting a card of the same suit is 12/51.

Selecting the third card: After selecting two cards, there are now 50 cards remaining in the deck. We want to choose another card of the same suit as the first two cards. There are 11 remaining cards of the same suit, so the probability is 11/50.

selecting the fourth card: After selecting three cards, there are now 49 cards remaining in the deck. We want to choose another card of the same suit as the first three cards. There are 10 remaining cards of the same suit, so the probability is 10/49.

Selecting the fifth card: After selecting four cards, there are now 48 cards remaining in the deck. We want to choose a card of a different suit than the previous four cards. There are 39 cards of a different suit, so the probability is 39/48.

To calculate the overall probability, we multiply the probabilities of each step together: (1/1) * (12/51) * (11/50) * (10/49) * (39/48) = 11/204, which is approximately 0.0539.

The probability of choosing 2 girls from a list of 6 girls and 6 boys can be calculated using combinations.

The number of combinations of choosing 2 girls out of 6 girls is given by the formula: C(6,2) = 6! / (6-2)!2! = 15.

So, the probability of choosing 2 girls is 15 / (C(12,2) = 66) = 15/66 = 5/22.

Therefore, the probability of Mr. Mackinson choosing 2 girls to lead the class field trip is 5/22 or approximately 0.227.

\( \frac{r}{6 } + 1 = 9 \\ \frac{r}{6} = 9 - 1 \\ \frac{ r }{6} = 8 \\ r = 48\)

Answer:

r = 48

Step-by-step explanation:

The goal is to get r on one side of the equation.

To do this do the same thing to both sides of the eqaution to keep it in balance.

r/6 + 1 = 9

Subtract 1 from both sides

r/6 = 8

multiply both sides by 6

r = 48

Answer:

Grapes=19.51

Step-by-step explanation:

Apples=$2.19 per pound

Grapes=$2.60 per pound

Apples+Grapes=20 pounds

A+G=20

A=20-G

Equation is

PaA+PgG=35.80

2.19A+2.60G=35.80

2.19(20-G)+2.60G=35.80

43.8-2.19G+2.60G=35.80

43.8-0.41G=35.80

-0.41G=35.80-43.8

-0.41G=-8

Divide both sides by 0.41

G=19.51 pounds

Recall

A=20-G

A=20-19.51

A=0.49 pounds

They ordered 19.51 pounds of grapes.

let us say they ordered 'x' pound of grapes.

so, the quantity of apples ordered = (20-x) pound

it is given that

cost of the apple= $2.19 per pound

cost of the grapes= $2.60 per pound

according to the given scenario,

total cost = $35.80

the total cost will be the sum of the cost of apples as well as grapes.

2.60x + 2.19(20-x) =35.80

-0.41x = 8

x = -19.51 pounds

therefore, they ordered 19.51 pounds of grapes.

When we subtract a velocity vector from another velocity vector, the result is B. another velocity.

When we subtract a velocity vector from another velocity vector, we are essentially finding the difference between the two velocities. This difference is also a velocity vector, but in a different direction and with a different magnitude. Therefore, the answer is another velocity, option B.

It is important to note that acceleration is a change in velocity, not the result of subtracting one velocity from another. Scalar refers to a quantity with only magnitude, whereas velocity is a vector quantity with both magnitude and direction. Displacement refers to the change in position of an object and is not directly related to subtracting velocity vectors.
