Step-by-step explanation:

8 + (22 + 15) = 8 + 37 = 45

To evaluate the expression, we must first perform the operations inside the parentheses. In this case, 22 + 15 = 37. Then we can add 8 to that result, which gives us 8 + 37 = 45. So the final value of the expression is 45.

Answer:

Using BODMAS, you are to solve the one in the bracket

22+15 which=37

then you add it to 8

Tasha has the highest batting average because 0.9(27/30) is greater than 0.8( 24/30 ) ( optionD)

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls.

The batting average for Jana is 12/15 = 0.8

The battling average for Tasha is 9/10 = 0.9

The battling average of Tasha is higher than that of Jana

0.6 can also be in form of 6/10

0.9 can also be in form of 9/10

therefore 8/10 = 24/30 and

9/10 = 27/30

Therefore Tasha has the highest batting average because 27/30 is greater than 24/30

The possible values of k are -11 and 11.

Given that equation is: x²-kx+28

Roots are: [tex]\alpha ,\alpha +3[/tex]

To find: the value of x:

The general quadratic equation is:

ax²+bx+c

Product of roots=c/a

sum of roots=-b/a

From given,

x²-kx+28=0

a = 1

b = -k

c = 28

Therefore,

Product of roots=28/1=28

sum of roots=-k/1=-k

Given roots are:

[tex]\alpha ,\alpha +3[/tex]

Therefore,

The two roots are two numbers whose difference is 3 and whose product is 28

Those two roots are 4 and 7 or -4 and -7

Then, the sum of roots is:

The measure of the side length CL is equal to 9m using trigonometric ratio of cosine 60° for thy right triangle ACL

The trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.

Angle m∠BAC = 180° - (m∠C + m∠ABC)

m∠BAC = 180° - (90° + 30°)

m∠BAC = 60°

line AL is an angle bisector so;

m∠CAL = 30° and m∠BAL = 30°

which implies triangle ∆ALB is an isosceles with line LB = AL = 18m

considering the right triangle ∆ACL;

angle m∠L = 180° - (90° + 30°)

m∠L = 60°

cos 60° = CL/18 {adjacent/hypotenuse}

1/2 = CL/18m {cos 60° = 1/2}

CL = 18m/2 {cross multiplication}

CL = 9m

Therefore, the side length CL is equal to 9m using trigonometric ratio of cosine 60° for the right triangle ACL.

The translations, reflections, and rotations are types of transformations that change an original object to form a new image, each with its own specific rule and properties. They are used in a variety of real-world applications to change the position or orientation of objects.

There are 3 types of Transformations :

(i) Translation: A translation involves moving an object from one place to another without changing its size or orientation.  

The algebraic rule for a translation is to add the same constant to each coordinate of each point

The Translations preserve congruence, meaning that corresponding parts of congruent figures will still be congruent after a translation.

An example of a real-world application of translation is moving a store to a new location.

(ii) Reflection: A reflection involves flipping an object over a line or point, creating a mirror image.

The algebraic rule for a reflection is to negate the value of one of the coordinates.

Reflections preserve orientation, meaning that the orientation of the reflected image is opposite that of the original object.

An example of a real-world application of reflection is looking at your reflection in a mirror.

(iii) Rotation: A rotation involves turning an object about a fixed point, called the center of rotation, through a certain angle.

The algebraic rule for a rotation is to multiply each coordinate by a rotation matrix.

Rotations preserve distance and angle measures, meaning that the lengths of corresponding parts and the angles between them are equal in the original and rotated images.

An example of a real-world application of rotation is turning a steering wheel to change the direction of a car.

To determine the submarine's depth, you would need to use trigonometry. The angle of depression (40 degrees) and the distance from the ship to the submarine (500 meters) form a right triangle.

You can use the tangent function (tan) to find the opposite side (depth) of the triangle, given the adjacent side (distance) and the angle.

Depth = distance * tan(angle of depression)

Depth = 500 meters * tan(40 degrees)

You can use a calculator or table to find the value of tan(40 degrees), which is approximately 0.8391.

Depth = 500 meters * 0.8391

Depth = 419.55 meters

So the submarine's depth is 419.55 meters deep.

Right triangles can be used to represent word problems involving angles of elevation and depression. When working right triangles, the trigonometric rates are used to break for the right triangle's sides and angles representing the problem.

3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is 0.25.

1. The probability of selecting exactly one tank with high-viscosity material is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success. In this case, n = 4, x = 1, and p = 24/24 = 1. Therefore, P(X = 1) = (4C1)1^1(1-1)^4-1 = 0.

An individual data point's residual is a measurement of how well a line fits it. Take a look at this straightforward data set with a line of fit through it.

The discrepancy between expected values of y (the dependent variable) and actual values of y is the residual for each observation. Relative to projected and actual y values, residual is equal to yi. Actual y value minus expected y value equals residual; therefore, r I = y I y i.

The solution of the equations using elimination method is x = 2.5, y = 5.25

The elimination method is a method used to solve systems of linear equations. It involves manipulating the equations in such a way that one of the variables is eliminated, resulting in an equation in one variable that can be easily solved.

8x+4y = 49 --- (1)

3x+2y = 21  ----(2)

To eliminate x, multiply (1) by 3 and multiply (2) by 8. Then subtract the result. That is:

3 × (8x+4y = 49)   = 24x + 12y = 147

8 ×(3x+2y = 21)    = 24x + 16y = 168

.......................................................................

                                          4y = 21

.........................................................................

4y = 21

y = 21/4

y = 5.25

Put y = 5.25 into (1):

8x+4y = 49

8x + 4(5.25) = 49

8x + 21 = 49

8x = 49 -21
