Answer:
Multiply the first equation by 4 and the second equation by -3:
-12x + 16y = 4
12x - 15y = -6
‣ Add the equations:
‣ Solve for y:
y = -2
‣ Substituting y = -2 into the first equation, we get:
-12x + 16 ⋅ (-2) = 4
‣ Solve for x:
x = -3
‣ Solution:
x = -3, y = -2)

Answer:
you are right
Step-by-step explanation:
Use the law of law of cos
c^2=a^2+b^2﹣2abcos√angle
(2√13)^2=52=4+36-24cos(a)
cos(a) = -12/24 = -1/2
a = 120 degrees
so yes, you are right
Graph the linear equation. Find three
points that solve the equation, then
plot on the graph.
3x - 4y = -18
5X=(X+1)×4
send some help
Answer:
x = 4
Step-by-step explanation:
So you multiply all in the ( x + 1) by 4 so 4 times x equals 4x and 4 times 1 is 4
5x = 4x + 4 subtract 3x because that is the only common thing on the other side you'll get
x = 4 and that's your answer

How many of the following numbers are divisible by 3, 6, and 9?
648 846 126 612 576
9514 1404 393
Answer:
5 (all of them)
Step-by-step explanation:
The sums of digits are ...
6+4+8 = 18
8+4+6 = 18
1+2+6 = 9
6+1+2 = 9
5+7+6 = 18
When the sum of digits is a multiple of 9, the number is divisible by 3 and 9.
When the number is also even (as all of these are), it is also divisible by 6.
All 5 of these numbers are divisible by 3, 6, and 9.
Answer:
All 5 of them.

Team A: 65, 67, 67, 68, 70, 70, 70, 71, 74, 77, 78, 78, 81, 81, 82 Team B: 63, 65, 67, 68, 70, 70, 71, 73, 74, 77, 77, 77, 78, 81, 84 Which of the following statements is a correct comparison of Team B to Team A? A. Team B has a larger median and a smaller interquartile range. B. Team B has a larger median and the same interquartile range. C. Team B has a smaller median and a larger interquartile range. D. Team B has a smaller median and the same interquartile range.
Answer:
B. Team B has a larger median and the same interquartile range.
The correct statement is,
D. Team B has a smaller median and the same interquartile range.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, We know that;
Based on the given data, the correct comparison of Team B to Team A is A. Team B has a larger median and a smaller interquartile range.
This is because the median score for Team B is 70, which is higher than the median score for Team A, which is 70.
The interquartile range for Team B is smaller because the scores are more tightly clustered around the median, indicating less variability in scores compared to Team A.
Thus, The correct statement is,
D. Team B has a smaller median and the same interquartile range.

There has been a great deal of controversy over the last several years regarding what types of surveillance are appropriate to prevent terrorism. Suppose a particular surveillance system has a 96% 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 200 million, and one of these 200 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
Answer:
0.9976 = 99.76% probability that he/she actually is a future terrorist
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Person identified as a future terrorist
Event B: Person is actually a future terrorist.
Probability that a person is identified as a future terrorist:
96% of [tex]\frac{1000}{200000000}[/tex]
100 - 99.8 = 0.2% of [tex]\frac{200000000-1000}{200000000}[/tex]
So
[tex]P(A) = 0.96\frac{1000}{200000000} + 0.002\frac{200000000-1000}{200000000} = 0.002[/tex]
Probability of being identified and being a future terrorist:
100 - 99.8 = 0.2% of [tex]\frac{200000000-1000}{200000000}[/tex]
[tex]P(A \cap B) = 0.002\frac{200000000-1000}{200000000} = 0.00199999[/tex]
What is the probability that he/she actually is a future terrorist
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.00199999}{0.00200479} = 0.9976[/tex]
0.9976 = 99.76% probability that he/she actually is a future terrorist

The first thing we need to do is find the formula for area of a trapezoid
The formula is
[tex]A=\frac{a+b}{2} h[/tex]
where a= base 1
b = base 2
and h = height
we are given all of the dimensions so all we have to do is plug them in
sp
[tex]A=\frac{12+4}{2} 4\\12+4=16\\\frac{16}{2} =8\\8*4=32[/tex]
so the area of the figure is
32 units ²
Answer:

Step-by-step explanation:
Find formula
A=a+b/2 h
a= base 1
b = base 2
h = height
Then plug everything in
