Answer:
0.68?
Step-by-step explanation:
I am not from English speaking country so I am not sure about the first sentence but the second
126n = 86 | /126
n = 86/126
n ≈ 0,68
Can somebody please help with this?
Answers
Since that second equation is equal to y, you can substitute the entire thing into the top equation, getting rid of the y and solving for x. It equals 3.
You can then plug 3 in for x on either equation, which should be 62.
What’s 3/6 as a mixed number

Answer:
It can't be made into a mixed number
Step-by-step explanation:
Identify the rule relating each term in the following sequence: 8, - 4, 2 - 1, 1/2, 1/4, 1/8
A: Divide by 2
B: Divide by -2
C: Multiply by -2
D: Multiply by 2
Answers
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!

n= -10
Step-by-step explanation:
50-20= 30 so -3n=30. So n= -10.
Answer:
n=-10
Step-by-step explanation:
-3n+20=50 move constant to the right hand side
-3n=50-20 subtract the numbers
-3n=30 divide both sides by -3 and the answer is n=-10

400 Suppose a particular surveillance system has a 99% chance of correctly identifying a future terrorist and a 99.8% chance of correctly identifying someone who is not a future terrorist. If there are 1,000 future terrorists in a population of 400 million, and one of these 400 million is randomly selected, scrutinized by the system, and identified as a future terrorist, what is the probability that he/she actually is a future terrorist
Answers
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)

1. Neena is listening to a song. It has a consistent beat. She counts 11 beats in 5 seconds. What is the constant of proportionality for the relationship of beats to minutes?
Answers
Answer:
132
Step-by-step explanation:
132
Step-by-step explanation:
First, find how many beats are in a minute by creating a proportion:
\frac{11}{5} = \frac{x}{60}
Cross multiply and solve for x:
5x = 660
x = 132
So, there are 132 beats in one minute.
This means the constant of proportionality is 132.

Depreciation is the decrease or loss in value of an item due to age, wear, or market conditions. We usually consider depreciation on expensive items like cars. Businesses use depreciation as a loss when calculating their income and taxes. One company buys a new bulldozer for $109600. The company depreciates the bulldozer linearly over its useful life of 16 years. Its salvage value at the end of 16 years is $17600. A) Express the value of the bulldozer, V, as a function of how many years old it is, t. Make sure to use function notation. B) The value of the bulldozer after 7 years is $
Answers
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

AB AC because of the definition of an isosceles triangle
BAC because corresponding parts of congruent triangles are congruent.
AABM 4 AACM because of the SAS triangle congruence criterion
BMCM because of the definition of a midpoint
AM A AM because of the Symmetric Property
Answers
Answer:
A. AB = AC because of the definition of an isosceles triangle
B. ∠B = ∠C because corresponding parts of congruent triangles are congruent.
D. BM = CM because of the definition of a midpoint
Step-by-step explanation:
A. An isosceles triangle is a triangle with two equal sides, hence:
AB = AC because of the definition of an isosceles triangle. option A is correct.
D. Since Point M is drawn as the midpoint of BC, hence:
BM = CM because of the definition of a midpoint. Option D is correct.
E. Reflexive property of congruence states that an angle, line segment, or shape is always congruent to itself. hence AM ≈ AM because of reflexive property.
AM ≈ AM because of the Symmetric Property is wrong. Option E is wrong.
C) The side - side - side (SSS) triangle congruence theorem states that if all the sides of two triangles are equal, then they are congruent triangles.
Since BM = CM, AM = AM and AB = AC, hence ΔABM = ΔACM because of the SSS triangle congruence criterion
ΔABM = ΔACM because of the SAS triangle congruence criterion is wrong. Option C is wrong.
D. Corresponding parts of congruent triangles are congruent. hence:
∠B = ∠C because corresponding parts of congruent triangles are congruent. Option B is correct

Corey Steinbruner is the marketing director for a new vitamin supplement and he wants to place ads in two magazines: Sports Illustrated and Men's Health. Corey estimates that each one-page ad in Sports Illustrated will be read by 4 million people and costs $2000 and each one-page ad in Men's Health will be read by 1 million people and costs $1000. Corey does not want to budget more than $14,000 on advertising and wants to place at least 3 ads in Sports Illustrated and at least 4 ads in Men's Health. a) Let LaTeX: xx be the number of ads in Sports Illustrated and LaTeX: yy be the number of ads in Men's Health. Write the objective function (with quantities in millions) to find the maximum number of readers reached by the ads.
Answers
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.

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

What is the angle measure of angle MPQ?
Answers
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°
