Step-by-step explanation:

The linear regression equation that represents this set of data is given as follows:

y = 1.05x - 10.43.

The estimated homework grade for a student with a test grade of 31 is given as follows:

39.46.

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator.

The points for this problem are given as follows:

(58, 52), (75, 66), (66, 68), (85, 74), (53, 38), (74, 65), (78, 76).

Inserting these points into a calculator, the equation is given as follows:

y = 1.05x - 10.43.

The estimated homework grade for a student with a test grade of 31 is x when y = 31, hence:

31 = 1.05x - 10.43

x = 41.43/1.05

x = 39.46.

The surface area of a cylinder can be found by adding the areas of the top and bottom circles, as well as the area of the side (lateral) surface.

The radius of the cylinder is 1 and one fourth centimeters, which can be written as 5/4 cm. The height of the cylinder is 3 and three fourths centimeters, which can be written as 15/4 cm.

The area of each circle is πr^2, where r is the radius. So, the area of the top and bottom circles is:

2π(5/4)^2 = 25/2 π square centimeters

The lateral surface area of a cylinder is given by the formula 2πrh, where r is the radius and h is the height. So, the lateral surface area of the cylinder is:

2π(5/4)(15/4) = 75/2 π square centimeters

Therefore, the total surface area of the cylinder is:

25/2 π + 75/2 π = 100/2 π = 50 π square centimeters

So, the exact surface area of the cylinder in terms of π is 50π square centimeters. None of the given options matches this answer.

The interest earned is $60 and the balance of the account is $460. The interest and the balance of the account will be both calculated with their given formulas.

An expense or payment for using borrowed money is interest; it is occasionally stated as a percentage of the principal borrowed. It could also be applied to the returns on investments or savings. Interest is the cost that a borrower typically reimburses a lender for the use of their funds.

A. We must use the formula-

Interest = Principal x Rate x Time, to calculate the interest earned.

Here, Interest = $400 divided by 0.03 and multiplied by 5.

Earned interest is $60.

B. We must utilize the formula-

Balance = Principal + Interest, to determine the account's balance.

Balance = $400 + computed interest in this instance.

Balance: $400 + $60.

The account's balance is $460.

You want to factor out the greatest common factor from ...

The greatest common factor is the largest expression that is a factor of both terms. Here, one term is a constant, so the GCF will be the largest constant that is a factor of both the coefficient and the constant.

For these numbers, your familiarity with multiplication tables will tell you the greatest common factors. More formally, you can find the GCF a couple of different ways.

You can factor the numbers involved, and identify the set of common factors. The GCF will be the product of the numbers in that set:

Repeatedly divide by the smaller of the two numbers or the remainder, until the remainder is 0. The last divisor is the GCF.

Factoring out the greatest common factor, we have ...

Answer:

The equation y + 2 = 3/4x can be written in slope-intercept form by isolating the y-term and rearranging the equation. The slope-intercept form of the equation is y = 3/4x - 2

Answer:

y = 3/4x - 2

Step-by-step explanation:

The slope intercept formula y = mx + b

so y + 2 = 3/4x

=> y + 2 -2 = 3/4x - 2

=> y = 3/4x - 2

Step-by-step explanation:

If the beetle is 15 mm in actual size, and the photo is increased to 778% of the actual size, then we can find the size of the beetle in the photo by multiplying its actual size by 7.78:

Size of beetle in photo = Actual size of beetle x 7.78

Substituting the given value of the actual size, we get:

Size of beetle in photo = 15 mm x 7.78

= 116.7 mm

Therefore, the size of the beetle in the photo is 116.7 mm.

74 meters

Step-by-step explanation:

The difference in Emile and Henry's speed is 1.5, and the lead for Henry is 45 meters, so 45÷1.5= 30 seconds which means Henry will go another 30 meters at 1 meter per second.

2. To make it a close race we want Henry to go a longer distance than Emile, so make it 74 meters, which means Emile will go only have 45+29 = 74 seconds to get to 74 meters, but Henry only have 29 seconds in total = 29*2.5 = 72.5 meters.  

Answer:

14x-15 = 15(3x-1)

(5 x 9x) - (5 x 3 )= 45x=15

(5 x 9x) + (5 x 3)= 45x=15

15(3x+1)= 45x+15

Step-by-step explanation:

-6.1 in mixed number form is -6 1/10, making it greater than -6 4/9. This is because, if the numbers were positive, -6 4/9 would be greater than -6.1, but since the numbers are negative, it's opposite.

Therefore, the answer is:

Answer:a

Step-by-step explanation:

The solution to the equation ax² + bx + c = 0 , has a graph that crosses the y-axis once and does not intersect the x-axis, then the equation has one real root and two complex conjugate roots that lie on either side of the axis of symmetry.

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

If the graph of the equation ax² + bx + c = 0 crosses the y-axis once, it means that the equation has one real root. This is because when x = 0, the equation becomes:

c = 0² + 0 + c = c

Therefore, the point (0, c) is on the y-axis, which means the graph crosses the y-axis once.

If the graph does not intersect the x-axis, it means that the discriminant b² - 4ac is negative. This is because the discriminant determines the nature of the roots of a quadratic equation, and when it is negative, the roots are complex (not real) and the graph does not intersect the x-axis.

So, the solution(s) of the equation ax² + bx + c = 0 are:

x = (-b ± √(b² - 4ac)) / 2a

Since the discriminant is negative, the term inside the square root is negative, and there are no real solutions for x. Instead, the solutions are complex conjugates of the form:

x = (-b ± i√(4ac - b²)) / 2a

where i is the imaginary unit. Since the real part of these solutions is -b/2a, which is the axis of symmetry of the parabola, and the parabola does not intersect the x-axis, the complex roots will be a conjugate pair that lie on either side of the axis of symmetry.

Hence , the quadratic equation is solved

Answer:

Step-by-step explanation:

y divided by  6x6=3x6

1. multiply first

 a) 6x6 = 36

  b) 3x6=18

  c) y/6 times 6 =3 x6 .....make it a fraction    Y over 6  times 6 over 1

  d)  y/6 times 6/1----cross off the two 6's

Now:  y=3x6

          y=18

6 times 6 = 36 and 6 times 3 = 18

36 = 18

So, 18 divided by y = 36

so, 18 times 36 = 648

Hence, y is divided by 648 to get 6 x 6
