Answers
Total 36 outcomes are possible on rolling two dices simultaneously
A sample space is a collection or a set of possible outcomes of a random experiment. The sample space is represented using the symbol, “S”. The subset of possible outcomes of an experiment is called events. A sample space may contain a number of outcomes that depends on the experiment
A dice has 6 possibilities (1,2,3,4,5,6) , thus two when dices thrown together will have 36 outcomes in it's sample space. It's sample space is shown in picture attached below.

What is a right-angled triangle?
A triangle is said to be a right-angled triangle if one of its inner angles is 90 degrees, or if any one of its angles makes a right angle.
What is the value of x?
(Consider the given figure for reference)

Answers
Answer:
(4, 3)
Step-by-step explanation:
#1. Isolate x:
3x + y = 15
y = 15 - 3x
Substitute and solve for x:
5x - 3y = 11
5x - 3(15 - 3x) = 11
5x - 45 + 9x = 11
5x + 9x = 11 + 45
14x = 56
x = 4
Substitute and solve for y:
y = 15 - 3x
y = 15 - 3(4)
y = 15 - 12
y = 3
Answer:
C. Solve the first equation for y
===================
Given system3x + y = 155x - 3y = 11If we are looking for substitution, then should solve one of the equations for one of the variables. This will allow us to substitute same into other equation and solve for the other variable.
Let's see what would be easy solution.
Equation 1Solving for x is not straight away (we isolate x and divide all terms by its coefficient) as it has coefficient of 3.
Solving for y is easy, we just need to isolate it:
3x + y = 15 ⇒ y = - 3x + 15Equation 2Both of the variables have coefficients that are not factors of the constant term, so the easiest option is to solve the first equation for y.
This gives us the answer choice C.
Clara writes the equation (x – 13)(x 8) = 196 to solve for the missing side length of a rectangle represented by the factor x 8. what is the missing side length represented by x 8 units of the rectangle?
Answers
Answer:
28 units
Step-by-step explanation:
First, we are going to solve the equation to find the value ^^
Let's solve the equation step by step
Step 1. Use the distributive property to destroy the parenthesis
Step 2. Subtract 196 to both sides of the equation
Step 3. Factor the expression
Step 4. Set each factor equal to zero and solve
Since we are dealing with lengths here, and lengths cannot be negative, the only valid solution is 28.
Now, we know from our problem that the missing side of the rectangle is given by the expression , so to find the actual length, we just need to replace with 8 in the given expression and simplify!
We can conclude that the missing side length represented by x + 8 units of the rectangle is 28 units.

In geometry, the area enclosed by a circle of radius r is pie π[tex]r^2[/tex].
How to round decimals?
Rounding decimals consists of rounding a decimal number to a certain number of decimal places, to save time and help us express really long numbers in shorter terms. There are certain rules to follow when rounding a decimal number. Put simply, if the last digit is less than 5, round the previous digit down. However, if it’s 5 or more than you should round the previous digit up. So, if the number you are about to round is followed by 5, 6, 7, 8, 9 round the number up. And if it is followed by 0, 1, 2, 3, 4 round the number down.
The area of circle is [tex]47.39cm^2[/tex].
Putting it in the formula we get
[tex]47.39cm^2[/tex] = π[tex]r^2[/tex]
[tex]r^2[/tex] = 47.39 / π
r^2 = 15.0847
r = 3.88 cm

Notice how Pattern 2 is Pattern 1 with 4 balls added in the bottom row.

Pattern 4 is Pattern 3 with 6 more balls.
Generalizing the trend, we expect Pattern [tex]n[/tex] to be identical to Pattern [tex]n-1[/tex] with [tex]n+2[/tex] more balls.
If [tex]b_n[/tex] is the number of balls in the [tex]n[/tex]-th pattern, then we have the recursive relation
[tex]\begin{cases} b_1 = 6 \\ b_n = b_{n-1} + n + 2 & \text{for } n>1 \end{cases}[/tex]
We can solve this recurrence by substitution. Using the definition of [tex]b_n[/tex], we have
[tex]b_{n-1} = b_{n-2} + (n-1) + 2 \\\\ \implies b_n = (b_{n-2} + (n-1) + 2) + n + 2 \\\\ \implies b_n = b_{n-2} + 2\times2 + \bigg(n + (n-1)\bigg)[/tex]
[tex]b_{n-2} = b_{n-3} + (n-2) + 2 \\\\ \implies b_n = (b_{n-3} + (n-2) + 2) + 2\times 2 + \bigg(n + (n-1)\bigg) \\\\ \implies b_n = b_{n-3} + 3\times2 + \bigg(n + (n-1) + (n-2)\bigg)[/tex]
and so on, down to
[tex]b_n = b_1 + (n-1)\times2 + \bigg(n + (n-1) + (n-2) + \cdots + 2\bigg)[/tex]
Recall that
[tex]\displaystyle \sum_{i=1}^n i = 1 + 2 + 3 + \cdots + n = \frac{n(n+1)}2[/tex]
Then we find
[tex]\displaystyle b_n = 6 + 2(n-1) + \sum_{i=2}^n i[/tex]
[tex]\displaystyle b_n = 2n + 4 + \left(\sum_{i=1}^n i - 1\right)[/tex]

Answers
The sample size required to estimate the fraction of people who are captured after appearing on the 10 most wanted list is 228.
Given standard deviation of 0.26 ,margin of error of 0.04, and confidence interval of 98%.
We have to determine the sample size required to estimate the fraction of people who are captured after appearing on the 10 ost wanted list.
We can find the sample size with the help of margin of error.
Margin of error is the difference between the calculated values and real values.
Margin of error=z*σ/[tex]\sqrt{n}[/tex]
where σ is standard deviation,
n is sample size and z is critial z value.
We have to find the z value for 98% confidence level from z table.
z value=2.326.
Put the values in the formula of margin of error.
0.04=2.326*0.26/[tex]\sqrt{n}[/tex]
[tex]\sqrt{n}[/tex]=2.326*0.26/0.04
[tex]\sqrt{n}[/tex]=15.119
squaring both sides we get

How to calculate the equation?Based on the information given, the radical equation that has an extraneous solution is 5✓x + 10 - 15 = 30.
This will be:
5✓x + 10 - 15 = 30
Collect like terms
5✓x = 30 - 10 + 15
5✓x = 35
✓x = 35/5
✓x = 7
x = 7² = 49
The equation that does not have an extraneous solution will be ✓x + 1 + 7 = 4. Here, ✓x = -4 and has no solution.
