Answer:

-23.21

there should be a two part for this and the answer would be D y= 0.15x - 23.21

Step-by-step explanation:

The line of best will be y = 0.15x - 23.21  and the y-intercept is -23.21 after applying the formula.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

The data is given:

R(x)     W(y)

808     93

768     94

655     66

684     81

637     86

619     75

613     61

609     69

563     55

The line of best fit can be written as:

y = mx + c

Here m is the slope of the line best fit and c is the y-intercept

Putting the values in the formula we get:

m = 0.15

c = -23.21

The line of best fit is:

y = 0.15x - 23.21

Thus, the line of best will be y = 0.15x - 23.21  and the y-intercept is -23.21 after applying the formula.

Answer:

W = 15. I hope this helped.

Step-by-step explanation:

Steps:

1.Add 19w to both sides.

11=−17w−19+19w

2.Simplify  -17w-19+19w to  2w-19

11=2w−19

3.Add 19 to both sides.

11+19=2w

4. Simplify  11+19  to  30.

30=2w

5.Divide both sides by 2.

30/2 = w

6.Simplify 30/2 to  15.

15=w

7.Switch sides.

w=15

Answer:

The statement that is not true is;

c) m∠ABO = m∠ODC

Step-by-step explanation:

With the assumption that the lengths AO, and OD are equal, we have that in ΔABO and ΔOCD, the following sides are corresponding sides;

Segment AO on ΔABO is a corresponding side to segment OD on ΔOCD

Vertices B and C on ΔABO and ΔOCD are corresponding vertices

Therefore;

Segments AB and OB on ΔABO are corresponding sides to segments OC and OD on ΔOCD respectively

Therefore, ∠ABO on ΔABO is the corresponding angle to ∠OCD on ΔOCD

Given that ΔABO ≅ ΔOCD, we have that ∠ABO ≅ ∠OCD

Therefore;

m∠ABO = m∠OCD by definition of congruency

Answer:

A

Step-by-step explanation:

We are given:

[tex]\cos(22f-1)=\sin(7f+4)[/tex]

Recall the co-function identity:

[tex]\sin(\theta)=\cos(90-\theta)[/tex]

Let θ = 7f + 4. So:

[tex]\sin(7f+4)=\cos(90-(7f+4))[/tex]

Substitute:

[tex]\cos(22f-1)=\cos(90-(7f+4))[/tex]

Remove the cosine:

[tex]\displaystyle 22f-1=90-(7f+4)[/tex]

Distribute:

[tex]22f-1=90-7f-4[/tex]

Subtract:

[tex]22f-1=-7f+86[/tex]

Add 7f and 1 to both sides:

[tex]29f=87[/tex]

Therefore:

[tex]f=3[/tex]

Answer:

slope is m= y_2-y_1/x_2-x_1 and the y-intercept is where the line crosses over the x-axis

Step-by-step explanation:

fill in the points and do the equation m= rise(y points)/ run(x points)

m=slope

(x_1, y_1) =coordinates of first point in the line

(x_2, y_2)=coordinates of second point in the line

Answer:

h = 11.61 foot

Step-by-step explanation:

Given that,

The length of a ladder, l = 12 foot

The bottom of the ladder is 3 ft from  the house.

We need to find how high does the top of the ladder reach. Let it is h. The length of the ladder will be the hypotenuse. 3 ft will be the base. So,

[tex]12^2=3^2+h^2\\\\h^2=144-9\\\\h=11.61\ \text{foot}[/tex]

So, the top of the ladder is at a height of [tex]11.61\ \text{foot}[/tex].

What is a word problem?

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

Let the two numbers be x and y.

Two numbers have a negative sum, but a positive product.

So, the two numbers are -x and -y.

Let us consider the two numbers be -2 and -3

Sum of two numbers = [tex]-2+(-3)[/tex]

⇒ [tex]-5[/tex]

Product of two numbers = [tex](-2)(-3)[/tex]

⇒ [tex]6[/tex]

Thus the sum have a negative number and the product is a positive product.

Hence we can conclude that the example of her numbers could be -2 and -3.

thats the answer.

Given:

The sequence is -8, -12, -16.

To find:

The nth and 52th term  of the given sequence.

Solution:

We have,

-8, -12, -16

It is an AP because the difference between consecutive terms are equal. Here, first term is -8 and the common difference is

[tex]r=a_2-a_1[/tex]

[tex]r=-12-(-8)[/tex]

[tex]r=-12+8[/tex]

[tex]r=-4[/tex]

The nth term of an AP is

[tex]a_n=a+(n-1)d[/tex]

Where, a is first term and d is common difference.

Putting a=-8 and d=-4, we get

[tex]a_n=-8+(n-1)(-4)[/tex]

[tex]a_n=-8-4n+4[/tex]

[tex]a_n=-4-4n[/tex]

Putting n=52, we get

[tex]a_{52}=-4-4(52)[/tex]

[tex]a_{52}=-4-208[/tex]

[tex]a_{52}=-212[/tex]

Therefore, the equation for the nth term of the given sequence is [tex]a_n=-4-4n[/tex] and the 52nd term of the sequence is -212.
