A pair of fair dice is tossed.
Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur.
The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.
Probability of event to happen
P(E) = Number of favourable outcomes [tex]/[/tex] Total Number of outcomes(a)) A total of 8 can be obtained with the following outcomes,
The sample space S contains n(S) = 36 elements when a pair of dice is tossed.
⇒{(2,6),(3,5),(4,4),(5,3),(6,2)} i.e. 5 outcomes.
⇒Required probability = [tex]\frac{5}{36}[/tex] = 0.1389
The probability of a total of 8 is 0.1389.
(b).
At most a total of 5 can be obtained with the following outcomes:
⇒{(1,1),(1,2),(1,3),(1,4),(2,1),(2,2),(2,3),(3,1),(3,2),(4,1)} i.e. 10 outcomes.
⇒Required probability =[tex]\frac{10}{36}[/tex] =0.2778
The probability of at most a total of 5 is 0.2778.
Therefore, the probability of total of 8 is 0.1389, the probability of at most a total of 5 is 0.2778.

c. Find an equation for the sequence
Answer:
a) See below.
b) Arithmetic sequence
[tex]\textsf{c)} \quad a_n=10n-7[/tex]
Step-by-step explanation:
Part (a)From inspection of the given table, t(n) increases by 10 each time n increases by 1.
Therefore:
[tex]\implies a_7=53+10=63[/tex]
[tex]\implies a_8=63+10=73[/tex]

Part (b)As the given sequence has a constant difference of 10, it is an arithmetic sequence.
Part (c)[tex]\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a_n$ is the nth term. \\ \phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]
The common difference is 10. Therefore:
d = 10To find the first term, a, substitute the value of d and one of the terms into the formula:
[tex]\begin{aligned}\implies a_4=a+(4-1)(10)&=33\\a+3(10)&=33\\a+30&=33\\&a=3\end{aligned}[/tex]
Therefore, to write an equation for the given arithmetic sequence, substitute the found values of a and d into the formula:
[tex]\implies a_n=3+(n-1)(10)[/tex]
[tex]\implies a_n=3+10n-10[/tex]

Solve 2 log x = log 64.
x= 1.8
x=8
x= 32
x=128
x=8.
Step-by-step explanation:1. Write the expression.[tex]2log(x)=log(64)[/tex]
2. Divide both sides of the equation by "2".[tex]\frac{2log(x)}{2} =\frac{log(64)}{2}\\ \\log(x)=\frac{log(64)}{2}[/tex]
3. Apply number "10" as the base of an exponent of each side of the equation.When a logarithm doesn't have it's base expressed (base is tipically written as a subscript) we can assume it'sbase is 10. Therefore, to solve this equation, take the following step:
[tex]10^{log(x)} =10^{\frac{log(64)}{2}} \\ \\x=10^{\frac{log(64)}{2}}\\ \\x=8[/tex]
4. Verify the answer.If the result is correct, then the equation should return the same value of both sides of the equal symbol (=) when we substitute the variable "x" by it's calculated value, 8.
[tex]2log(8)=log(64)\\ \\1.806179974=1.806179974[/tex]
As you can tell, the same number appears on both sides of the equal symbol, this means that the result is correct!
Answer:
x = 8
Step-by-step explanation:
Given expression:
[tex]2\log x=\log 64[/tex]
[tex]\textsf{Apply the log power law}: \quad n\log x=\log x^n[/tex]
[tex]\implies \log x^2=\log 64[/tex]

There are four real roots for the quadratic-like equation x⁴ + 9 · x² - 10 = 0: x₁ = + √(- 9 / 2 + 11 / 2), x₂ = + √(- 9 / 2 - 11 / 2), x₃ = - √(- 9 / 2 + 11 / 2) and x₄ = - √(- 9 / 2 - 11 / 2)
How to solve a quadratic-like equation by factoring
In this problem we find a quadratic-like equation of the form a · x²ⁿ + b · xⁿ + c = 0, where a, b, c are real coefficients and whose roots must be found. This can be done by completing the square and clear variable x. First, write the polynomial:
x⁴ + 9 · x² - 10 = 0
Second, use the following substitution: u = x²
u² + 9 · u - 10 = 0
Third, complete the square:
u² + 9 · u + 81 / 4 = 10 + 81 / 4
u² + 9 · u + 81 / 4 = 121 / 4
Fourth, factor the expression and clear variable u:
(u + 9 / 2)² = 121 / 4
u + 9 / 2 = ± 11 / 2
u = - 9 / 2 ± 11 / 2
Fifth, reverse the substitution and clear variable x:

In the accompanying diagram, isosceles trapezoid has bases DC and AB with measures of 6 meters
and 18 meters respectively. If altitude CE is drawn and AC has a measure of 14 meters, find the length
of altitude CE to the nearest meter.
The length of the isosceles trapezoid height CE is 14 meters.
How do you calculate the length?To find the length of the height CE of the isosceles trapezoid, we can use the Pythagorean theorem.
The isosceles trapezoid CE is the hypotenuse of the right triangle formed by height CE and distance AC. CE is also the height of the trapezoid. Let the length of CE be 'x'
The Pythagorean theorem states that the square of the length of the hypotenuse of a right triangle (CE) is equal to the sum of the squares of the lengths of the other two sides (AC and CE).
x² = AC² + CE²
We know that AC = 14 meters and CE = x.
So x² = 14² + x²
x² = 196 + x²
x² = x² + 196
0 = 196
x = √196 = 14
Therefore, the length of height CE is 14 meters.

What do you add to 5 5/8 to make 7 as an improper fraction?
Answer: We need to add 1 7/8 to 5 5/8 to make 7 as an improper fraction. ✅
PLEASEEEE GIVE BRANLIEST
Step-by-step explanation: To add 5 5/8 to a number to make 7 as an improper fraction, we need to convert 5 5/8 to an improper fraction.
To convert a mixed number to an improper fraction, we take the whole number, multiply it by the denominator of the fraction, and add the numerator. So, 5 5/8 becomes (5 x 8) + 5 / 8 = 40 + 5 / 8 = 45/8.
Now, we can add 45/8 and the number that we need to add to make 7 as an improper fraction.
45/8 + x = 7
To find x, we can subtract 45/8 from both sides of the equation:
x = 7 - 45/8
x = 1 7/8
So, we need to add 1 7/8 to 5 5/8 to make 7 as an improper fraction. ✅

differentiate f(x) =5√x using first principle
Answer: To differentiate a function using the first principle, we first need to know the function and it's original value. Given that the function is f(x) = 5√x .
The first principle of differentiation states that the derivative of a function f(x) at a point x is approximately equal to the change in f(x) for an infinitesimal change in x. We can use this principle to find the derivative of a function f(x) at a point x by calculating the limit of the ratio (f(x+dx)-f(x))/dx as dx approaches zero.
To differentiate f(x) = 5√x with respect to x using the first principle, we take the following steps:
Find the change in f(x) as x changes by dx, which is f(x + dx) - f(x)
Divide that change by dx to find the slope of the function at that point
Take the limit of that slope as dx approaches zero
So:
f(x + dx) = 5√(x + dx)
f(x) = 5√x
change in f(x) = f(x + dx) - f(x) = 5√(x + dx) - 5√x
slope = change in f(x) / dx
= (5√(x + dx) - 5√x) / dx
The limit as dx approaches zero is the derivative of the function,
lim (dx->0) [(5√(x + dx) - 5√x) / dx]
= lim (dx->0) [(5(x+dx)^1/2 - 5x^1/2) / dx]
= 5 * lim (dx->0) [(x+dx)^1/2 - x^1/2] / dx
= 5 * (1/2)x^(-1/2)
So the derivative of the function f(x) = 5√x is (5/2)x^(-1/2)
This is the slope of the function at a point x, which is the rate of change of the function at that point x.
