Consider the equation −3+(−9.25)+m=0 .

Answers

Let's solve your equation step-by-step.

−3−9.25+m=0

Step 1: Simplify both sides of the equation.

−3−9.25+m=0

−3+−9.25+m=0

(m)+(−3+−9.25)=0(Combine Like Terms)

m+−12.25=0

m−12.25=0

Step 2: Add 12.25 to both sides.

m−12.25+12.25=0+12.25

m=12.25

Answer:

m=12.25

a bricklayer stacks bricks in 2 rows with 10 bricks each in each row on top of each row there is a stack of 6 bricks how many bricks are there in total​

Answers

Let me see.

Row 1 = 10 bricks

Row 2 = 10 bricks

On top of each row there are 6 bricks.

Two rows times 6 bricks per row is 12 bricks.

Total = 20 + 12 or 32 bricks.

what is the distance between (-8,5) and (-1,5)

Answers

Answer:

7 units

Step-by-step explanation:

(see attached for reference)

given two points (x₁, y₁) and (x₂, y₂), the formula for distance between two points is given as

Distance, D = √(  (x₂-x₁)² + (y₂-y₁)²  )

in our case, we are given

(x₁, y₁) = (-8,5)

(x₂, y₂) = (-1,5)

simply substitute the values into the equation above:

D = √(  (x₂-x₁)² + (y₂-y₁)²  )

= √{  [ (-1)-(-8) ]² + (5-5)²  }

= √{  [ (-1 + 8) ]² + (0)²  }

= √[ (7) ² ]

= 7 units (answer)

We want to factor in the following expression:

16x⁴-(y-1)²

We can factor the expression as (U+V)(U-V) where U and V are either constant integers or single-variable expressions.

1) What are U and V?

2)Factor the expression.​

We have an expression:

= 16x⁴-(y-1)²

or

= (4x²)²-(y-1)²

Using the identity:

a² - b² = (a + b)(a- b)

(4x²)²-(y-1)² = (4x² + (y-1))(4x² + (y+1))

The value of U = 4x²

V = (y-1)

The factor of the expression is:

(4x² + (y-1)) and (4x² + (y+1))

Thus, the value of U and V are 4x² and (y-1) respectively and the factor of the expression is (4x² + (y-1)) and (4x² + (y+1))

Ava earns $3,000 in 1 month at her job. How much will Ava earn in 20 months?
Use the drop-down boxes to show how to solve the problem.

Ava Finds _________. Ava will earn __________ in 20 months.

Answers

Answer:

$60,000

Step-by-step explanation:

If Ava earns at a constant rate of $3,000 for 1 month, then just multiply $3,000 by how many months she works.

3,000 x 20 = 60,000

If Ava earns $3,000 in one month, she will earn $60,000 in 20 months.

Based on the amount that she earns per month, we can find out that in 20 months, Ava will earn $60,000.

Ava earns $3,000 per month she works.

If she worked for 20 months, that monthly amount would be multiplied by 20 as shown below:

= Salary per month x number of months worked

Solving would give:

= 3,000 x 20

= $60,000

In conclusion, Ava would make $60,000 in 20 months.

M Is the midpoint of AB. If AB = 3x +14, and AM = 2x-1, find x and MB.​

Answers

Answers:

x = 16

MB = 31

==================================================

Work Shown:

M is the midpoint of AB

This means AM is half as long as AB and AM = MB

Put another way, AB is twice as long as AM

AB = 2*AM

3x+14 = 2*(2x-1)

3x+14 = 4x-2

14+2 = 4x-3x

16 = x

x = 16

AM = MB

MB = AM

MB = 2x-1

MB = 2*16-1

MB = 32-1

MB = 31

Step-by-step explanation:

y=7x+43

y=2x+13

(choose one equation &multiply by ‒1 to be y=0)

‒y=‒7x‒43

y=2x+13

0=‒5x‒30

we got the equation this (‒5x‒30=0) now we can solve x

‒5x‒30=0

‒5x=30

‒5x/‒5=30/‒5

x=‒6 (now we got the value of x, then we will find tge value of y by substitute )

y=2x+13

y=2(‒6)+13

y=‒12+13

y=1

therefore the pairs will be (‒6,1)

Correct question is;

Tanya walked for 17 minutes from her home to a friend that lives 1.5 kilometers away. D(t) models Tanyas remaining distance to walk in kilometers, t minutes since she left home. What number type is more appropriate for the domain of d?

Answer:

0 ≤ t ≤ 17 ; (0, 17)

Step-by-step explanation:

We are told that she has walked for 17 minutes from her home to a friend that lives 1.5 kilometers away.

Now, we want to find the domain of numbers that shows her remaining distance.

Since she spent 17 minutes, then it means in modeling remaining distance it could be from 0 to 17 minutes as the case may be. Thus, the domain can be written as;

0 ≤ t ≤ 17 ; (0, 17)

The probability of a randomly selected adult in one country being infected with a certain virus is 0.004. In tests for the​ virus, blood samples from 15 people are combined. What is the probability that the combined sample tests positive for the​ virus? Is it unlikely for such a combined sample to test​ positive? Note that the combined sample tests positive if at least one person has the virus.

Answers

Answer:

The probability is [tex]P(R) = 0.0583 [/tex]

Step-by-step explanation:

From the question we are told that

  The probability that selected adults are affected by virus is  p =  0.004

  The probability that adults are not affected by virus is  [tex]q= 1- p = 1-0.004 = 0.996[/tex]

    The sample size is  n =  15

 Generally from the question we are told that    

The probability that the combined sample tests positive is equal to the probability that  at least one person test positive for the  virus

So  

The probability that the combined sample tests positive for the​ virus is equal to  

  1- the probability that non of the adults selected tested positive for the virus

Generally the probability that  non of the adults selected tested positive for the virus is  

      [tex]P(k) = q^n[/tex]

=>    [tex]P(k) = q^{15}[/tex]

=>    [tex]P(k) = 0.996^{15}[/tex]

=>    [tex]P(k) =  0.9417 [/tex]

The probability that the combined sample tests positive for the​ virus is mathematically represented as

        [tex]P(R) = 1 - P(k)[/tex]

=>     [tex]P(R) = 1 - 0.9417 [/tex]

=>     [tex]P(R) = 0.0583 [/tex]

One of the wagers in roulette is to bet that the ball will stop on a number that is a multiple of 3. (Both 0 and 00 are not included.) If the ball stops on such a number, the player wins double the amount bet. If a player bets $5, compute the player's expectation. (Round your answer to two decimal places.)

Answers

Answer:

The player's expectation is a loss of 20 cents.

Step-by-step explanation:

In a game of roulette, there are 38 slots where the ball can stop.

The slots are numbered as follows: {0, 00, 1, 2, 3 ..., 36}.

So, N = 38.

The slots which are multiples of 3 are:

S = {3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33 and 36}

So, n (S) = 12.

Let X = the ball stops on a number that is a multiple of 3

The probability that the ball stops on a number that is a multiple of 3 is:

[tex]P(X)=\frac{n (S)}{N}=\frac{12}{38}=0.32[/tex]

It s provided that the player wins double the amount bet if the ball stops on a number that is a multiple of 3.

Compute the player's expectation as follows:

[tex]E(X)=\sum X\cdot P(X)[/tex]

        [tex]=(\$10\times 0.32)+(-\$5\times (1-0.32))\\\\=\$3.20-\$3.40\\\\=-\$0.20[/tex]

Thus, the player's expectation is a loss of 20 cents.
