Step-by-step explanation:

slopev=

[tex]diffrence \: in \: y \: coordinate \\ diffrence \: in \: x \: coordinate[/tex]

so

Y=11_5 =6

X = -7_(-3) = -4.

Answer:

a. V = $109,600  - $5,750(t)

b.  $69,350

Step-by-step explanation:

a. The expression of the value of the bulldozer is as follows

V = $109,600 - (m) × (t)

where,

m = depreciation

t  = time in years

Now the equation would be

$109,600 - 16(m) = $17,600

m = ($109,600 - $17,600) ÷ (16)

= $5,750

Now the expression would be

V = $109,600  - $5,750(t)

b. Now the value of the bulldozer is

= $109,600 - $5,750 × 7 years

= $109,600 - $40,250

= $69,350

The value of [tex]x[/tex] is approximately -1.531.

Step-by-step explanation:

Let [tex]3.3^{2\cdot x + 1}-103^{x+1} = 0[/tex], we proceed to solve this expression by algebraic means:

The value of [tex]x[/tex] is approximately -1.531.

Answer:

125°

Step-by-step explanation:

Find the value of x first.

5x = 3x + 50 (corresponding angles are congruent)

Subtract 3x from each side

2x = 50

Divide both sides by 2

x = 25

Angle MPQ = 3x + 50

Plug in the value of x

Angle MPQ = 3(25) + 50 = 125°

Answer:

90

Step-by-step explanation:

81/x=90/100

8100=90x

90=x

The total number of problems given in exam was 90.

Percentage, which is a relative figure used to denote hundredths of any quantity. One percent (symbolised as 1%) is equal to 100 parts; hence, 100 percent denotes the complete amount, and 200 percent designates double the amount specified.

Divide one number by the other, then multiply the result by 100 to get the percentage of the two numbers.

A student correctly answered 81 problems.

Grade received by student is 90%

Let the total number of question given in the test be 'x'.

Thus,

90% of x = 81

(90/100)x = 81

x = (81×100)/90

x = 90

Therefore, the total number of question allotted to the student is 90.

Answer:

1.236 × 10^(-3)

Step-by-step explanation:

Let A be the event that the person is a future terrorist

Let B the event that the person is identified as a terrorist

We are told that there are 1,000 future terrorists in a population of 400 million. Thus, the Probability that the person is a terrorist is;

P(A) = 1000/400000000

P(A) = 0.0000025

P(A') = 1 - P(A)

P(A') = 1 - 0.0000025

P(A') = 0.9999975

We are told that the system has a 99% chance of correctly identifying a future terrorist. Thus; P(B|A) = 0.99

Thus, P(B'|A) = 1 - P(B|A)

P(B'|A) = 1 - 0.99

P(B'|A) = 0.01

We are told that there is a 99.8% chance of correctly identifying someone who is not a future terrorist. Thus; P(B'|A') = 0.998

Hence: P(B|A') = 1 - P(B'|A')

P(B|A') = 1 - 0.998

P(B|A') = 0.002

We want to find the probability that someone who is identified as a terrorist, is actually a future terrorist. This is represented by: P(A|B)

We can find it from bayes theorem as follows;

P(A|B) = [P(B|A) × P(A)]/[(P(B|A) × P(A)) + (P(B|A') × P(A')]

Plugging in the relevant values;

P(A|B) = [0.99 × 0.0000025]/[(0.99 × 0.0000025) + (0.002 × 0.9999975)]

P(A|B) = 0.00123597357 = 1.236 × 10^(-3)

Answer:

Step-by-step explanation:

From the given information:

x = number of ads in sports illustrated

y = number of ads in Man's health

Thus, the total ads read by z = (4x +y) million people

The objective function to maximize Z (millions) is:

Z = 4x + y

To determine x & y; constraint to,

x  ≥ 3,  y  ≥  4

Budget constraint:  2000x + 1000y ≤ 14000

By approaching the graphically

If we draw the line x = 3 , y = 4

Then;

2000x + 1000y = 14000

2x + y = 14

Corner points are A (3,4), B(5,4), C(3,8)

At A(3,4):

Z = 4(3) + 1 (4) = 16

At B(5,4):

4(5) + 1 (4) = 24

At C(3,8):

4(3) + 1(8) = 20

Thus, Z = 24 million.    x = 5, y = 4

Therefore;

they should place 5 ads in sports illustrated.

4 ads in man's health to maximize the number of 24 million readers.

Answer:

B: Divide by -2

Step-by-step explanation:

The only logical conclusion would be divide by -2, though that may not be the entire correct answer. Why?

Firstly, the sequence of 8, -4, 2, -1 only follows division by -2. Division by 2 would result in 8, 4, 2 and 1, multiplication by -2 would result in 8, -16, 32, -64, and multiplication by 2 would result in 8, 16, 32 and 64. Hence, the only logical conclusion would be division by -2.

However, this rule breaks down as we go into the fractions. -1 / -2 is 1/2, sure, but (1/2) / -2 should be - 1/4, and not 1/4. Hence, as we go into the fractions, the rule should have changed to division by 2 instead.

The only solution to unite the whole sequence would be to correct 1/4 to -1/4, and maybe OP should check whether that is the case.

Hope this helped!

On edge 2021

To calculate this percentage, we suggest using this formula:

% / 100 = Part / Total

Substituting the provided values:

60/100 = Part / 20

Performing cross multiplication:

60 x 20 = 100 x Part, or

1200 = 100 x Part

Now just divide by 100 and get the answer:

Part = 1200/100 = 12
