Answer:
-2Step-by-step explanation:
Find the missing value of x in the arithmetic sequence below.
6, 2, x, -6, -10
6 - 4 = 2
2 - 4 = -2
-2 -4 = -6
-6 -4 = -10
☯︎ Let us find common difference,d by subtracting first term from second .i e.,\( a_2-a_1\) ,where \(a_1\) and \(a_2\) are first and second term .
✰common difference,d= 2-6 = -4
General term of Arithmetic Sequence,
\(\boxed{a_n = a+(n-1)d}\)
where,
\(a_n\) = nth term a = first term n = number of term d = common differenceSo,
❄︎\(a_3 = a+(3-1)d\)

Find the equation of the line that passes through (–3, 2) and the intersection of the lines x–2y=0 and 3x+y+5=0.
I need the intersection point of the lines and the equation of the line.
Answer:
\(\frac{19}{7}\)x+\(\frac{11}{7}\)y+5=0
Step-by-step explanation:
the intersection of x-2y=0 and 3x+y+5 is (\(\frac{-10}{7}\);\(\frac{-5}{7}\))
=> the line : \(\frac{19}{7}\)x+\(\frac{11}{7}\)y+5=0
Answer:
\(Point \ of \ intersection = (\frac{-10}{7} , \frac{-5}{7})\\\\Equation \ of \ line : y = -\frac{19}{11}x - \frac{35}{11}\)
Step-by-step explanation:
Find intersection of the given lines :
x - 2y = 0 => x = 2y ----------- ( 1 )
3x + y = - 5 -------------------- ( 2 )
Substitute ( 1 ) in ( 2 ) :
3x + y = - 5
3 ( 2y ) + y = - 5
6y + y = - 5
7y = - 5
\(y = -\frac{5}{7}\)
Substitute y in ( 1 ) :
x = 2y
\(x = 2 \times \frac{-5}{7} = - \frac{10}{7}\)
\(Therefore , \ point \ of \ intersection\ is ( -\frac{10}{7}, -\frac{5}{7} )\)
To find the equation of the line passing through ( - 3, 2) and point of intersection :
Standard equation of a line : y = mx + b , where m is the slope, b is the y intercept.

\(= \frac{\frac{-5}{7}-(2)}{\frac{-10}{7} - (-3)}\\\\= \frac{-5- 14}{-10 + 21}\\\\=\frac{-19}{11}\\\\=-\frac{19}{11}\)
Step 2 : Equation of the line :
\((y - y _1) = m (x - x_1)\\\)
\((y - 2 ) = -\frac{19}{11}(x -( -3))\\\\(y - 2 ) = -\frac{19}{11} (x+ 3)\\\\y = -\frac{19}{11} (x+ 3) + 2\\\\ y = -\frac{19}{11}x +(-\frac{19}{11} \times 3) + 2\\\\y= - \frac{19}[11}x +(\frac{-57}{11} + 2)\\\\y= - \frac{19}{11}x +(\frac{-57+ 22}{11})\\\\y= - \frac{19}{11}x +(\frac{-35}{11})\\\\\)

the probability of winning a certain lotter is 1/51,949. for people who play 560 times, find the standard deviation for the random variable x, the number of wins
The standard deviation for the random variable X, the number of wins, is approximately 0.10341.
Probability of winning a certain lottery \(= 1/51,949\)
560 times were played overall.
Let X represent the random variable that represents the number of victories out of 560 plays.
The probability of winning in one play is \(p = 1/51,949\). The probability of not winning in one play is \(q = 1 - p\)
\(q = (51,949 - 1) / 51,949\)
\(q = 51,948 / 51,949.\)
What X should actually be is:
\(E(X) = np\)
\(E(X) = 560 * (1/51,949)\)
\(E(X) = 0.010793\)
The variance of X is:
\(Var(X) = npq\)
\(Var(X) = 560 * (1/51,949) * (51,948/51,949)\)
\(Var(X) = 0.010699\)
The value of X's standard deviation is
\(SD(X) = \sqrt{Var(X)}\)
\(SD(X) = \sqrt{0.010699}\)
\(SD(X) = 0.10341\)(approx)
Therefore, the standard deviation for the random variable X, the number of wins, is approximately 0.10341.

A multiple choice test has 10 questions each of which has 4 possible answers, only one of which is correct. If Judy, who forgot to study for the test, guesses on all questions, what is the probability that she will answer exactly 3 questions correctly?
a-0.2816
b-0.0021
c-0.5006
d-0.0156
e-0.2503
option a-0.2816. To find the probability that Judy will answer exactly 3 questions correctly, we can use the binomial probability formula. In this case, the number of trials is 10 (since there are 10 questions), the probability of success is 1/4 (since there is only one correct answer out of 4 possible choices), and we want to find the probability of getting exactly 3 successes.
The binomial probability formula is:
P(X=k) = (n choose k) * p^k * (1-p)^(n-k)
Where:
- P(X=k) is the probability of getting exactly k successes
- (n choose k) represents the number of ways to choose k items out of n items
- p is the probability of success on a single trial
- k is the number of successes
- n is the number of trials
Using this formula, we can calculate the probability as follows:
P(X=3) = (10 choose 3) * (1/4)^3 * (3/4)^(10-3)
(10 choose 3) = 10! / (3! * (10-3)!)
= 10! / (3! * 7!)
= (10 * 9 * 8) / (3 * 2 * 1)
= 120
Now we can substitute the values into the formula:
P(X=3) = 120 * (1/4)^3 * (3/4)^(10-3)
= 120 * (1/64) * (3/4)^7
= 120 * (1/64) * (2187/16384)
= 0.2816
Therefore, the probability that Judy will answer exactly 3 questions correctly is 0.2816.
The correct answer is option a-0.2816.

there were three apples , 1 mixed fruit, 2 grape, and 4 tropical fruit juice boxes in the cooler at the picnic. What is the probability that, when Jill reaches into the cooler to grab two juice boxes without replacing them, she grabs two that are grape?
Answer:
1/45 ≈ 0.022
Step-by-step explanation:
There are originally 10 juice boxes in the cooler, 2 of which are grape.
The probability that the first juice box is grape is 2/10.
The probability that the second juice box is grape is 1/9.
The probability of both is (2/10) (1/9) = 1/45 ≈ 0.022.
f(x)=log5x what Is the range of the function
The range of the function f(x) = log5x is (-∞, +∞).The function f(x) = log5x represents the logarithm base 5 of x. To determine the range of this function, we need to consider the possible values that the logarithm can take.
The range of the logarithm function y = log5x consists of all real numbers. The logarithm function is defined for positive real numbers, and as x approaches 0 from the positive side, the logarithm approaches negative infinity. As x increases, the logarithm function approaches positive infinity.
The range of the function is the set of all possible output values. In this case, the range consists of all real numbers that can be obtained by evaluating the logarithm
log5(�)log 5 (x) for �>0 x>0.
Since the base of the logarithm is 5, the function log5x will take on all real values from negative infinity to positive infinity. Therefore, the range of the function f(x) = log5x is (-∞, +∞).
In other words, the function can output any real number, ranging from negative infinity to positive infinity. It does not have any restrictions on the possible values of its output.

Finding Missing Angles and Sides and Round to the nearest tenth.
(FOR ALL PLEASE)
The right triangle, like the other triangles, has three sides, three vertices, and three angles. The difference between the other triangles and the right triangle is that the right triangle has a 90 angle.
To find missing angles and sides and round to the nearest tenth, you can use different methods depending on the given information and the type of triangle or shape involved.
Some common methods include:
Trigonometric ratios (sine, cosine, tangent) for right triangles.
Angle sum property or exterior angle property for triangles.
Pythagorean theorem for right triangles.
Law of cosines and law of sines for non-right triangles.
To help find the missing angles and sides of a triangle, you need certain information about the triangle, such as known angle and side measurements, or information about the properties of the triangle.
Without this information, no concrete calculations can be made.
Provide the necessary information or describe the problem in more detail and we will help you find the missing corners and sides of the triangle and round it to tenths.
Remember to always check if any additional information is given, such as side lengths or angles ' 7 and to apply the appropriate formula or property to find the missing value.

Leading coefficient of F(x)=-4x^2-9x^5+7x^3+4x^4
Answer:
-9
Step-by-step explanation:
To solve this problem, you first need to put this problem in degree descending order.
monoidalTo do this, you first put the mononoimal with the highest exponent (The one with the most value).
This is done below:
\(F(x)=-4x^2-9x^5+7x^3+4x^4\\\\\) - This is the original problem just rewritten
\(F(x)=-9x^5-4x^2+7x^3+4x^4\) - You move the -9x first because it has the highest exponent of 5
\(F(x)=-9x^5+4x^4-4x^2+7x^3\)exponent - We put the 4x next because the expinet of 4 is higher than both 2 and 3
\(F(x)=-9x^5+4x^4+7x^3-4x^2\)because - Next, we put the 7x before the -4x because it has a higher exponent
After doing this, we can see that the leading monomial is \(-9x^5\). The leading coefficient is the number in front of the variable or, in this case, -9.
