Answer:

2 and 4 is repeated mode of the data

Answer:

2 and 4

Step-by-step explanation:

Answer:

P + Q = 90

P = 90 - Q

Cos (p) = cos (90-Q) = sinQ = 4/5 (given)

You can find CosQ from the triangle of Q

CosQ = sqrt (5^2 - 4^2) / 5 = 3/5

Required = CosP + CosQ = 4/5 + 3/5 = 7/5

Answer:

1 20%, 0.2

2 1/4, 0.25

3 50%, 0.5

4 6/9

Step-by-step explanation:

When there's a linear relationship, the least-squares method to determine the regression coefficients b0 and b1 will be y = 0.750 + 0.50x.

The meaning of the slope, b1, in this problem is the coefficient of x which is the slope. Here, b1 = 0.50. It implies that one unit change in x will be 0.5 unit change in y.

To predict the mean tear rating when the plate gap is equal to 0 goes thus:

y = 0.75 + (0.05 × 0)

y = 0.75 + 0

y = 0.75

Lastly, the relationship between the plate gap and the tear rating is a positive one.

Step-by-step explanation:

$3 = 2 Dinars

$x = 22 Dinars

3/2 = x/22

multiply 3 by 22 and divide by 2

multiply 2 by x and divide 2

which will give answer to $33.

Don't know if it makes sense

Answer:

5

Step-by-step explanation:

Neither the laws of sines nor the law of cosines can be used to solve the triangle. The correct option is the third option - neither law can be used

The law of sines is written as

[tex]\frac{sinA}{a}=\frac{sinB}{b}= \frac{sinC}{c}[/tex]

Where a,b, and c are sides of any given triangle and A,B, and C are the angles.

This law is used when we are given either

The law of cosines is written as

a² = b² + c² -2bc cosA, or

b² = a² + c² - 2ac cosB, or

c² = a² + b² -2ab cosC

Where a,b, and c are sides of any given triangle and A,B, and C are the angles.

This law is used when we are given either

Now, for triangle xyz, which the measures of angles X,Y, and Z are known, neither law can be used to solve the triangle.

Hence, neither the laws of sines nor the law of cosines can be used to solve the triangle. The correct option is the third option - neither law can be used

Answer:

  720 miles

Step-by-step explanation:

We are given a distance and a fraction of the total that it represents. This lets us write the relation ...

  252 = 0.35D . . . . . . where D is the total distance traveled

  252/0.35 = D = 720 . . . . divide by the coefficient of D

Step-by-step explanation:

[tex]midpoint = ( \frac{ - 2 + 6}{2} , \frac{ - 4 + 2}{2} ) \\ [/tex]

[tex]midpoint = ( \frac{4}{2} , \frac{ - 2}{2} ) \\ [/tex]

[tex]midpoint = (2, - 1)[/tex]

Answer:

That statement is true, but you do not always need the two.

Let's say that we had a problem, given the radius is 5, and we have to find the diameter.

First step is to define A

[tex]A = \pi r^2[/tex]

Second, redefine r as the actual radius to avoid confusion.

[tex]r = 5[/tex]

Third, set up an equation with the given values where you are multiplying pi by the radius.

[tex]\pi r^2 = \pi *r^2[/tex]

Fourth but not least, get the actual value.

[tex]\pi * r^2 = 79[/tex] rounded to nearest whole number

Answer:

True

Step-by-step explanation:

Definitely true.  If the shorter legs of the given triangle are a and b and the longest side is c, then if a^2 + b^2 = c^2, the triangle is a right triangle.  Otherwise it is not a right triangle.

Answer:

x = 8.98782862707

Step-by-step explanation:

Base on the given we can infer that we are solving for x:

Given equation:

1000x+27x+5.5=9236

Combine similar terms

1027x + 5.5 = 9236

Subtract both side by 5.5

1027x + 5.5 = 9236

             -5.5      -5.5

-------------------------------------

1027x = 9230.5

Now divide both sides by 1027x

9230.5 / 1027

x = 8.98782862707

Answer:

A. and D.

Step-by-step explanation:

Hey there!

In order to to find the point at which these two equations intersect at, you need to first rewrite the equations if needed so that they are in the form:

[tex]y=mx+b[/tex]

or

[tex]y=ax^2+bx+c[/tex]

The first equations needs to be rewritten

[tex]3x+5=y+4x[/tex]

make [tex]y[/tex] by itself

[tex]3x+5-4x=y[/tex]

Simplify LHS

[tex]y=-x+5[/tex]

Now we have it in slope-intercept form

Looking at the equation, we can tell that the slope of the line is [tex]-1[/tex] and the y-intercept is 5

Now you can graph this equation easily (image down below)

The second equation is already in form so there is no need to rewrite anything

We can go straight to graphing (image down below)

Now plot both equations on the same graph (image down below)

Slope=

Equation in point slope form

Answer:

[tex]y=-4x+1[/tex]

Step-by-step explanation:

We have been given two points on the line, so:

[tex]\textsf{let}\:(x_1,y_1)=(-1,5)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(1,-3)[/tex]

Calculate the slope using the slope formula:

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-3-5}{1-(-1)}=-4[/tex]

From inspection of the graph, it appears that the y-intercept (where the line crosses the y-axis) is at (0, 1).  However, just to be sure, use the point-slope form of linear equation.

Point-slope form of linear equation:  [tex]y-y_1=m(x-x_1)[/tex]

(where m is the slope and (x₁, y₁) is a point on the line)

[tex]\implies y-5=-4(x-(-1))[/tex]

[tex]\implies y-5=-4x-4[/tex]

[tex]\implies y=-4x+1[/tex]

Therefore, the equation of the line in slope-intercept form is:

[tex]y=-4+1[/tex]
