Step-by-step explanation:
The U.S. government has devoted considerable funding to missile defense research over the past 20 years. The latest development is the Space-Based Infrared System (SBIRS), which uses satellite imagery to detect and track missiles ( Chance, Summer 2005). The probability that an intruding object (e.g., a missile) will be detected on a flight track by SBIRS is 0.8. Consider a sample of 20 simulated tracks, each with an intruding object. Let x equal the number of these tracks on which SBIRS detects the object. (a) Is x (approximately) a binomial random variable? Group of answer choices No Yes
Answers
Answer: Yes
Step-by-step explanation:
Given that :
Probability of success (p) = 0.8
Number of simulations (n) = 20
Number of tracks on which infrared system detects object = x
To test if it is binomial random variable :
For a binomial distribution :
P(x) = nCx * p^x * (1 - p)^(n-x)
Since the variables given are enough to create and use a binomial probability distribution, then x is approximately a binomial random variable.

X+3y - 2z=2
3x+2y+z=13
-2x+3y - 3z= -5
Answers
Answer:
{x,y,z}={1,3,4}
Step-by-step explanation:
System of Linear Equations given :
[1] x + 3y - 2z = 2
[2] 3x + 2y + z = 13
[3] -2x + 3y - 3z = -5
Solve by Substitution :
// Solve equation [2] for the variable z
[2] z = -3x - 2y + 13
// Plug this in for variable z in equation [1]
[1] x + 3y - 2•(-3x-2y+13) = 2
[1] 7x + 7y = 28
// Plug this in for variable z in equation [3]
[3] -2x + 3y - 3•(-3x-2y+13) = -5
[3] 7x + 9y = 34
// Solve equation [3] for the variable y
[3] 9y = -7x + 34
[3] y = -7x/9 + 34/9
// Plug this in for variable y in equation [1]
[1] 7x + 7•(-7x/9+34/9) = 28
[1] 14x/9 = 14/9
[1] 14x = 14
// Solve equation [1] for the variable x
[1] 14x = 14
[1] x = 1
// By now we know this much :
x = 1
y = -7x/9+34/9
z = -3x-2y+13
// Use the x value to solve for y
y = -(7/9)(1)+34/9 = 3
// Use the x and y values to solve for z
z = -3(1)-2(3)+13 = 4
Solution :
{x,y,z} = {1,3,4}

PLEASE ANSWER QUICKLY
Answers
Answer:
$422.50
Step-by-step explanation:
If the bike is marked down by 35% then the final sale price will be 65% of the original price (since 100% - 35% = 65%).
Convert 65% into a decimal: 65% = 65/100 = 0.65
Therefore, 65% of $650 = 0.65 × 650 = $422.50

A parking lot is 400 yards long and 300 yards wide. You would want to make a miniature version
of this in your production design course. If you make it 10 inches long, how wide should it be?
Answers
If the scale I make for the parking lot is 10 inches long, it should be 7.5 inches wide.
What is a scale?Scale is a term to refer to a drawing and design method in which an object or space and its actual measurements are taken as a reference and subsequently reduced or increased while maintaining the proportions between their measurements.
How to calculate the length of the width of the parking lot to scale?To calculate the width of the parking lot to scale, it is necessary to perform the following mathematical operation.
We need to figure out how much 100 yards is on the inch scale model. So if 400 yards is 10 inches we must divide this value by 4 as shown below:
10 ÷ 4 = 2.5Based on the above, 100 yards equals 2.5 inches on this model. So if your width is 300 yards, the length in inches would be 7.5 inches.

Answers
Answer:
Line u shows the movement of the ladybug. Because line v goes farther than line u
Step-by-step explanation:
Because line v goes farther than line u
The ladybug's motion is depicted in line u. Because line v is moving farther than line u.
What is Speed?The amount of the shift in approach per unit of time or the size of the displacement over time for an object can be used to describe speed, which would be a scalar quantity in everyday language and kinematics.
The maximum speed that can be maintained when a period grows closer to zero is the starting speed.
By dividing the object's distance traveled by the duration of the interval, the mean pace of the object for the given period is calculated. Speed and velocity are not always the same thing.
The line u and v show the position of the two bugs, but the line that shows the ladybug's movement is line u because line v is moving farther than line u.

f(a+h)-f(a)/h= for h≠0
Answers
Answer & step-by-step explanation:
[tex]f(a)[/tex] is simply calculating by replacing a in lieu of x
[tex]f(a) = 3-3a+5a^2[/tex]
Same difference for [tex]f(a+h)[/tex], just be careful with products and squares:
[tex]f(a+h) = 3-3(a+h)+5(a+h)^2 = 3-3a-3h+5a^2+10ah+5h^2 = 3-3a+5a^2 -3h+10ah+5h^2[/tex]
In the last step i just reorganized terms so that everything containing h was at the end.
Finally, for the incremental ratio, writing it as 1/h for the sake of font sizes:[tex]\frac{f(a+h)-f(a)}h = \frac1h[(3-3a+5a^2-3h+10ah+5h^2)-(3-3a+5a^2)]=\\\frac1h(-3h+10ah+5h^2) = 10a-3 +5h[/tex]

Those two are right triangles because when you add the squares of the first two it should give you the square root of the third number
a^2 + b^2 = c^2
So
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
Therefore they are right triangles
But 1 & 2 aren’t right triangles because when you add the squares of the first two number, it doesn’t equal to the square root of the third number.
