A lock consist of 4 dials where each dial has 6 letters what is the probability of guessing the right combination in one try’s

Answer:53/6

Step-by-step explanation:

Let X be the other rational number

-5/6+X=8

Add 5/6 to both sides

-5/6+5/6+X=8+5/6

0+X= 53/6 (inverse property)

X=53/6. (Identity property)

The interest rate of the bank R is 2.5% and interest rate of the bank Q is 3%.

What is compound interest?

Compound interest is calculated on the principal as well as the interest accumulated over the previous period. It differs from simple interest in that interest is not added to the principal when calculating interest for the following period.

Here the given equation represents the amount in compound interest.

Using compound interest formula then

=> A = P\((1+\frac{R}{100})^n\)

According to the question the equation for trust bank is

=> R =350 \((1+0.025)^n\)

comparing with compound interest formula then

=> \(\frac{R}{100}= 0.025\)

=> R = 0.025× 100 =2.5%

Now the equation of other bank is

=> Q = 350\((1+0.03)^n\)

Comparing with compound interest formula then

=> \(\frac{R}{100}= 0.03\)

=> R = 0.03×100 = 3%

Hence the interest rate of the bank R is 2.5% and interest rate of the bank Q is 3%.

The value of the height of the cone is 38 units

The formula for calculating the circumference of a cone is represented as;

Circumference = 2πr

Now, substitute the value to determine the radius, we have;

24π = 2πr

Divide by the coefficient of r

r = 24π/2π

r = 12 units

The formula for the volume of a cone is;

Volume = πr²h/3

Substitute the values

The number of students per teacher is 23.

The number of students per tutor is 9.

The number of tutors needed for 90 students is 10 tutors.

In order to determine the number of students per teacher and per tutor, divide the total number of students by the number of teachers and by the number of tutors.

Division is the mathematical operation that is used to determine the quotient of two or more numbers. Division entails grouping a number into equal groups using another number. The sign used to denote division is ÷

Number of students per teacher = total number of students / total number of teacher

69 / 3 = 23 students per teacher

Number of students per tutor = total number of students / total number of tutors

The equation for the line of best fit is given as follows:

y = 50x/3.

The slope-intercept equation for a linear function is presented as follows:

y = mx + b.

The parameters of the definition of the linear function are given as follows:

From the graph, when x = 0, y = 0, hence the intercept b is given as follows:

b = 0.

Hence:

y = mx.

When x = 3, y = 50, hence the slope m is given as follows:

3m = 50

m = 50/3.

Answer: The true statements about the graph of the function are:

The range of the function is {y : y ≤ 6} ⇒ 2nd

The function is increasing over the interval (–∞ , –2) ⇒ 3rd

The function has a positive y-intercept ⇒ 5th

Step-by-step explanation: Lets explain how to solve the problem

- The function f(x) = -x² - 4x + 2 is a quadratic function represented

 graphically by a downward parabola with maximum vertex

∵ The form of the quadratic function is f(x) = ax² + bx + c

∵ The coordinates of the vertex of the parabola are (h , k) where

  h = -b/2a and k = f(h)

∵ a = -1 , b = -4

∴ h = -(-4)/2(-1) = 4/-2 = -2

∵ k = f(h)

∴ k = -(-2)² - 4(-2) + 2 = -(4) - (-8) + 2

∴ k = -4 + 8 + 2 = 6

∴ The vertex of the parabola is (-2 , 6)

* Look to the attached figure to find the true statements

∵ The greatest value of the function is 6 ⇒ y-coordinate of the vertex

∵ The range of the function is the values y-coordinates of the points

 on the parabola

∴ The range of the function is {y : y ≤ 6}

- The domain of the function is {x : x ∈ R} or (-∞ , ∞)

∵ The value of y increasing after -∞ to the x-coordinate of the vertex

∵ x-coordinate of the vertex is -2

∴ The function is increasing over the interval (–∞ , –2)

- The parabola intersect the y-axis at point (0 , 2)

∵ The y-intercept is the intersection between the parabola and the

  y-axis

∵ The parabola intersect the y-axis at point (0 , 2)

∴ The y-intercept is 2

The coordinates of the transformed figure are: A ’(-1, -2), B ’(-3, -2), C ’(-2, 4)

When a shape is rotated, it must be rotated through a point, here itis rotated around the origin

The coordinates of the triangle is given as:

A(1, 2), B(3, 2), C(2, 4) is rotated 90 degree

The rule of 90 degrees clockwise rotation is:

x, y = -x, -y

So, we have:

A(1, 2) which becomes (-1, -2)

B(3, 2), which becomes (-3, -2)

C(2, 4)  which becomes (-2, -4)

Hence, the coordinates of the transformed figure are:

A ’(-1, -2), B ’(-3, -2), C ’(-2, 4)

In order for mn to be even, m must be even or n must be an even number.

The relationship between two propositions when the subject and predicate of one are respectively the negation of the predicate and the negation of the subject of the other.

Suppose that the statement “m is even or n is even” is not true. Then both m and n are supposed to be odd. Let’s see if the product of two odd numbers is an even or an odd number:

Let n and m be equal to 2a +1  and 2b + 1 respectively, then their product is:

                 (2a +1) (2b + 1) = 4ab + 2a + 2b + 1

                                       = 2(2ab +a + b) + 1

This shows that the expression 2(2ab +a + b) + 1  is of the form 2n +1,  thus the product is odd. If the product of odd numbers is odd, then mn is not true to be even. Therefore, in order for mn to be even, m must be even or n must be an even number.

The value of the composite function t(s (2)) is 8

From the question, we have the following parameters that can be used in our computation:

s(x) = -x + 5

t(x) = 2x + 2

The composite function t(s(x)) is calculated as

t(s(x)) = 2s(x) + 2

Substitute the known values in the above equation, so, we have the following representation

t(s(x)) = 2(-x + 5) + 2

Again, substitute the known values in the above equation, so, we have the following representation

t(s(2)) = 2(-2 + 5) + 2

Evaluate

t(s(2)) = 8
