In triangle IJK , O is the intersection of the three medians . If IN = 12 find IK. please help

Answer:

51 degrees

Step-by-step explanation:

Complementary angles add up to 90 degrees. This means we can write an equation, where a represents the measure of the acute angle (which we need to find the larger one) and a + 12 is the measure of the larger angle.

a+(a+12)=90

2a+12=90

2a=78

a=39

Now add 12 to a to find the value of the larger angle.

39+12= 51

So the larger angle equals 51 degrees.

Therefore , the solution of the given problem of linear equation comes out to be  y = 7.

A model of linear regression is one that applies the formula y=mx+b. B is the slope, and m is the y-intercept. Despite the fact because both y and x are distinct components, the previous sentence is frequently referred as a "mathematical formula with two variables." Bivariate linear equations only have two variables. The application domains of linear equations have zero solutions in all cases. The equation for a simple linear equation is Y=mx+b, where m stands for the slope and b for the y-intercept. Y=mx+b, where m stands for slopes and b for the y-intercept, is how the equation is expressed.

Here,

The sample mean for all 8 students is 4.8 hours per week.

The arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.

To find the new sample mean, we need to add the new student's exercising time to the total time for the previous 7 students, and then divide by the total number of students.

The total exercising time for the previous 7 students is 7 x 5.2 = 36.4 hours.

The total exercising time for all 8 students is 36.4 + 2 = 38.4 hours.

So the sample mean for all 8 students is 38.4 / 8 = 4.8 hours per week.

Answer:

m<3 is 95 degrees.

Step-by-step explanation:

m<2 is 55*, the other angle is 30* because 180-150 is 30, and so by process of elimination it is 95*

Hope this helps!

Answer:

m<3=95°

Step-by-step explanation:

m<2 is vertically opposite an angle of 55°, and since vertically opposite angles are equal, we can say m<2=55°.

The unmarked angle in the triangle containing m<2 and m<3 is on a straight line with an angle of 150°. Since the angles along a straight line add to 180°, this unmarked angle=180-150°=30°.

The angles in a triangle always add to 180°, so the sum of m<3, m<2 and the unmarked angle should be 180°:

m<3+55°+30°=180°

m<3+85°=180°

m<3=95°

The other acute angle is 37°.

The student made two errors. First of all, a triangle doesn't have two angles, it has three. Since it's a right triangle, there's an immediate 90° angle that's a part of the triangle. Secondly, an acute angle is lower than 90°. 127° is an obtuse angle. Anyway, we know that the other acute angle is 37° because 53° + 37° = 90, and since we have a right triangle, 90° + 90° = 180°.

Answer: When m = 3/1 = 3

Step-by-step explanation:

A system of equations will have infinitely many solutions when the equations are equivalent, that is, they represent the same line. This can happen when the equations are multiples of each other.

In this case, the first equation y = mx + 3 is a standard form equation of a line with slope m and y-intercept (0,3). The second equation -x + 3y = 9 can be written in slope-intercept form as y = (3/1)x + (-9/1).

To find the value of m that gives the system infinitely many solutions, we have to compare the slope of the two equations. The slope of the first equation is m, and the slope of the second equation is 3/1. Thus, the system will have infinitely many solutions when m = 3/1 = 3.

The interest paid on a loan can be calculated using the formula:

What does money interest mean?

You pay interest on any loans or borrowings of money. the portion of the loan's value that lenders use to calculate interest. Consumers can earn interest by lending money (via a bond or certificate of deposit, for example), or by putting money into an interest-bearing bank account.

Interest = Principal x Risk Percentage x Term (in months) x LIBOR

In this case, the principal is $550,000, the risk percentage is 2.0%, the term is 3 months, and LIBOR is 2.8%. So the interest paid at the end of the term is:

Interest = $550,000 x 2.0% x 3 x 2.8% = $15,660

Therefore, the interest paid at the end of the term is $15,660.

Note: I have used the risk percentage and LIBOR to calculate the interest rate which is (2.0%+2.8%) and then multiplied it with the principal and term to get the interest paid.

g(f(x)) = -3x^2 - 19 and -f(x) + 3g(x) = = x^2 + 9x + 24  .

What is a function ?

function can be defined as which related an input to the given any output of the following.

Given ,

f(x) = -x^2- 8

g(x) = 3x+5

So , the value of (gof)(-4) =

gof(x) = 3 (-x^2 - 8 ) + 5

= -3x^2 - 24 + 5

= -3x^2 - 19

gof(-4) =  -3 (-4*-4) -19

= -3 (16 ) - 19

= -48- 19

= -67

gof(-4) = -67

g(x) = 3x+5

g(-4) = 3*-4 + 5

= -12 + 5

= -7

f(g(-4)) = - (-7*-7) - 8

= -49 - 8

= -57

g(f(x)) = gof(x) = 3 (-x^2 - 8 ) + 5

= -3x^2 - 24 + 5

= -3x^2 - 19

-f(x) = -(-x^2-8) = x^2 + 8

3g(x) = 3 * (3x+5)

= 9x + 15

-f(x) + 3g(x) = x^2 + 8 + 9x + 15

= x^2 + 9x + 24

Hence, By calculating , the values of gof(-4) = -67 , f(g(-4)) = -57  ,
