Find the probability for one roll of a number cube.
P(number greater than or equal to 7)

A. 1/7
B. 0
C. 1/6
D. 1

Answers

Answer 1
The probability of rolling a 7 is = 1/6.
Answer 2
Answer: B) 0

The only possible outcomes on a standard number cube (aka a die or dice) are {1,2,3,4,5,6}

It is not possible to roll a 7 or larger, so we say the probability is 0. A probability of 0 means "impossible".

In a population of elderly war veterans, the probability that a veteran will have been exposed to agent orange (a militarized herbicide) and develop cancer is 0.35. The probability is 0.75 that a veteran exposed to agent orange will develop cancer. The average age of the veterans is 67 years old. What is the probability that a random veteran will have been exposed to agent orange

Answers

Answer:

Probability that a random veteran will have been exposed to agent orange is 0.4667

Step-by-step explanation:

P(exposed to agent cancer and develop cancer) = 0.35

P(develop cancer given he is already exposed to agent orange) = 0.75

P(is exposed to agent cancer) = ?

 

P(A given B) = P(A and B)/P(B),

P(develop cancer | exposed to agent orange)  = P(develop cancer and exposed to agent orange)/P(exposed to agent orange)  

0.75 = 0.35/P(exposed to agent orange)  

P(exposed to agent orange) = 0.35/0.75

P(exposed to agent orange) = 0.4667

In 1988, a certain model of car cost $17000. What would be the cost of that car in 2017 dollars?

Answers

Answer:

$66,092.50

Step-by-step explanation:

In 1988, the car cost $17,000

Annual inflation over this period was 3.54% from 1988 to 2017

After adjusted for inflation, $17,000.00 in 1978 is equal to $66,092.50 in 2017

Therefore, the cost of that car in 2017 is closest to $66,092.50

A virus strain is 0.00000015 meters in length. What is the length in scientific notation?

Answers

Answer:

1.5*10^-5

Step-by-step explanation:

Hey there! I'm happy to help!

Scientific notation is writing a number 1-10 multiplied by ten to a certain power. We see that we can write the number 1.5 to fit this.

We want to multiply by ten to a negative power as the decimal has been moved to the left. Let's count how many times we need to move the decimal over to get to 1.5.

If we count this, we have to move 7 places to get the decimal in the right spot. Therefore, to write this in scientific notation, we would write 1.5×10^-7.

PLs give brainliest if someone else answers!

The measurement of the angle ∠ SRW in the given figure is 95°

What are angles?

An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

Angles formed by two rays lie in the plane that contains the rays.

Angles are also formed by the intersection of two planes.

Given is a figure, lines VS and TW are intersecting at the point R, making angles, TRV, TRS, VRW and SRW,

We need to find the measurement of the angle SRW,

Here, we can see that the angles TRV and SRW, are vertically opposite angles,

Vertically opposite angles :-

Vertically opposite angles are angles that are opposite one another at a specific vertex and are created by two straight intersecting lines. Vertically opposite angles are equal to each other.

Therefore, we can say that, ∠ TRV = ∠ SRW

Since, ∠ TRV = 95°

Therefore, ∠ SRW = 95°

Hence, the measurement of the angle ∠ SRW in the given figure is 95°

Type your numeric answer and submit

Answers

Answer: Hence, the proportion of head lands obtained from the total number of tosses is 0.583

Step-by-step explanation:

Given the following :

Total number of coin tosses = 60

Total number of times coin landed on head = 35

Proportion of head landings obtained :

Total number of head landings obtained / total number of coin tosses

Proportion of head landing obtained :

Answers

Answer: Average salary per month=$1,743

(NB--- I am thinking you meant  $1,977, $1,560, $1,820 instead of $1.977 $1.560. $1.820 ie a comma instead of decimal point, so i corrected and solved )

Step-by-step explanation:

Step 1

Average salary  =Total amount of employees salaries/ Number  of employees

Step 2

Employee         Amount of salary per month

Wilma                $1,820

Mavis,                $1,615

Martha,             $1,977

Tom                   $1,560.

Total =               $ $6,972

Average salary per month  = $1,820 + $1,615+$1.977+$1.560/4 =$6,972/4= $1,743

x = 18

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

x^2 + 24^2 = ( 12+x)^2

FOIL the right side

x^2 +576 = 144 + 24x + x^2

Subtract x^2 from each side

576 = 144 + 24x

Subtract 144 from each side

576-144 = 24x

Divide each side by 24

A total of 587 tickets were sold for the school play. They were either adult tickets or student tickets. There were 63 fewer student tickets sold than adult tickets. How many adult tickets were sold?

Answers

Answer:

'325 adult tickets' is the ACTUAL answer

Step-by-step explanation:

I am editing this because I made a mistake beforehand

Let's say that x=adult tickets. If we subtract 63 tickets from adult tickets you get the number of children's tickets, so that means x+(x-63)=587. Or,

2x-63=587

Add 63 to both sides to get 2x=650. Divide it all by 2, and you get 325 adult tickets

What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given expression can be rewritten as,

8a³ - b³​

= (2a)³ - b³

It is known that x³-y³​ can also be written as (x-y)(x²+xy+y²). Therefore, the above expression can be written as,

= (2a)³ - b³

= (2a - b)[(2a)² + (2a × b) + b²]

= (2a - b)(4a² + 2ab + b²)

Hence, the given expression 8a³-b³​ can be rewritten in factor form as (2a-b)(4a²+2ab+b²).
