Answer: r = -0.14 ; weak correlation

Answer:

Step-by-step explanation:

The height of the ladder using trigonometric ratio is 9.8 feet.

Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.

For the given situation,

The slanting height of the ladder = 10 foot

The ladder makes an angle = 78°

Let height of the ladder be 'h'.

The below diagram shows the ladder position.

The height of the ladder can be found by using trigonometric ratio,

[tex]sin \theta=\frac{perpendicular}{hypotenuse}[/tex]

⇒ [tex]sin78=\frac{h}{10}[/tex]

⇒ [tex]0.9781=\frac{h}{10}[/tex]

⇒ [tex]h=9.781[/tex] ≈ [tex]9.8[/tex]

Hence we can conclude that the height of the ladder using trigonometric ratio is 9.8 feet.

Answer:

d

Step-by-step explanation:

not a bc it has to be negative

not c bc its has to be negative

not b bc the slope is -1/2

IT'S D

Answer:

D

Step-by-step explanation:

from the picture, we know that the slope is negative to begin, since the line is going on a downward direction from left to right. this eliminated A and C instantly.

Now we also can see the graph crossed at 3 for the y intercept, which is another reason to eliminate A and C.

we must then find the show of the line.

let us use to point (0,3) since this is the y intercept and (6,0) since this is the x intercept. to find the slope, m, at must use the equation

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

so, let's label (0,3) as point 1 and (6,0) as point two. then,

x1 = 0

y1= 3

and

x2= 6

y2=0

Now we just plug in and simplify.

[tex] m = \frac{0 - 3}{6 - 0} = \frac{ - 3}{6} = - \frac{1}{2} [/tex]

we now have our slope and y intercept, so we can plug them into our equation

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

where m is the slope and b is the y intercept.

our equation is thus

[tex]y = - \frac{1}{2} x + 3[/tex]

so, the answer is D

Answer:

[tex] \frac{ 3}{4} \times 100\% \\ 75\%[/tex]

Answer:

The answers are A, B and C.

Step-by-step explanation:

To solve the inequality you first have to use Distributive Property. You should get -3k + (-21) > -57

Next Divide 21 on both sides. -57/21 is -36

You should have -3k > -57

Divide -3 on both sides. -57/-3 is 12

You should end up with k > 12

And you never used -5, 0 or 8 in the equation and the question asks to choose the following that isn't included in the solution so your answers are A, B and C.

Hope This Helps! ^^

Answer:

No

Step-by-step explanation:

I would not agree with Jayna because using the distributive property, you can get:

4(a + 2) = 4(a) + 4(2) = 4a + 8

Jayna did not get the right answer because she did not distribute the 4 to the 2 in a + 2 and she only multiplied a by 4.

Answer:

68.7 minus t.

Step-by-step explanation:

PR = 5 units.

Given:

Right triangle

Hypotenuse = P(–3, 2), Q(1, –3)

R = located in the third quadrant.

To calculate the length of PR,

(i) First make a sketch of the points P and Q. The diagram is attached to this response.

(ii) As shown in the diagram, the point R is located in the third quadrant and its distance from P is from point -3 to 2 on the y-axis.

There are 5 points between -3 and 2. Therefore, the length PR = 5 units

Answer: About 3 hours and 5 minutes to paint the room together.

Step-by-step explanation:

Sally can paint 1/5 of the room in an hour and Steve can paint 1/8 of the room in an hour.

Room/Hour

1/5 ± 1/8 =8/40  

8/40+5/40=13/40

How long to paint the room?

13/40 x 1= 40/13

40÷13=3.0777

So the answer will be Sally and Steve can paint the room in about 3 hours and 5 minutes

Since altitude of the triangle and slant height is given, we can find the base of the triangle using Pythagorean:

It has 9 faces and the total surface area is:

Answer:

1/3

Step-by-step explanation:

We use the formula y2-y1/x2-x1. The two points that I would use are (3,-1) and (-3,-3). This means that the equation will be -3--1/-3-3. This is equal to -2/-6. This is also equal to 1/3. Therefore, the slope is 1/3.

Answer: 1440 took the test

Answer:

192 ft²

Step-by-step explanation:

Area of rectangular backyard = 1248 ft²

Width of backyard = 52 ft

Length = x

Area of rectangular backyard = Length * width

1248 = x * 52

x = 1248 / 52

x = 24 feets

Hence, x = height of triangular garden

Area of triangle = 1/2 base * height

Area = 1/2 * 16 * 24

Area = 192 ft²

Step-by-step explanation:

If Issac has finished 8/10 problems in the homework, and Phil has completed all of it, it can be concluded that Phil completed 10/10. 10/10 would equal a whole, or in this case, the entire homework. If Issac completed 8 problems, and Phil completed 10, subtract both values to find that Issac completed -2 more problems than Phil.

Answer: C(x) = 13x +95​

Step-by-step explanation:

Here's the remainder of the question:

If C(x) represents the total cost and x represents the number of people attending the banquet, which equation shows the total cost? A C(x)=95x – 13 B C(x)=13x – 95 C C(x)=95x +13 D C(x)=13x +95​

Based on the information given in the question, the total cost will be:

= 95 + 13(x)

= 95 + 13x

Therefore, the correct answer will be C(x)=13x +95​

Answer:

The number is less than - 0.708

Step-by-step explanation:

Given - 3 is added to 5 times a certain number and the result is multiplied by 5 the final answer is not more than 2 less than the number

To find - What is the number ?

Proof -

Let a number be x

Given that,

3 is added to 5 times a certain number

So,

The expression becomes 3 + 5x

Now,

Given that, the result is multiplied by 5

So,

The expression becomes (3 + 5x)× 5

Now,

Given that,

The final answer is not more that 2 less than the number.

So,

The equation becomes

(3 + 5x)× 5 ≤  x - 2

⇒15 + 25x ≤ x - 2

⇒15 + 2 + 25x - x  ≤  0

⇒17 + 24x  ≤  0

⇒24x  ≤  -17

⇒x ≤ - [tex]\frac{17}{24}[/tex]

⇒ x ≤ -0.708

∴ we get

The number is less than - 0.708
