Answer:

A. r = -0.93

Step-by-step explanation:

First, if there is a negative correlation, the correlation coefficient will be negative.

This eliminates answer choices C and D, which are positive.

If there is a strong correlation, the correlation coefficient will be closer to 1, or -1 (since the correlation is negative).

Since -0.93 is closer than -0.23 to 1, it has a stronger correlation.

So, the correct answer is A. r = -0.93

Answer:

$131422

Step-by-step explanation:

Given :

Amount owed = $124,850

Commison on sale = 5%

Let :

Sale price of bulldozer = x

Sale price = amount owed + 5% of sale price

x = 124850 + 0.05*x

x = 124850 + 0.05x

x - 0.05x = 124850

0.95x = 124850

x = 124850 / 0.95

x = 131421.05263

To the nearest dollar = $131422

Points on the graph:

Substitute coordinates into equation and solve for and and b:

Find k:

Answer:

a=8

b=9/4

k = 27

Step-by-step explanation:

y = ab^x

We know that a is the initial value or when x = 0

We know the point (0,8) so a = 8

y = 8 b^x

Using the point (1,18) for x and y we can find b

18 = 8 * b^1

18/8 = b

9/4 = b

Now

y = 8 * ( 9/4) ^ x

Letting x = 1.5

k = 8 *(9/4)^1.5

k = 27

Answer: 6

Step-by-step explanation:

To get 3/4 miles to 1 mile we must take the reciprocal of the number and multiply it.

[tex]\frac{3}{4}[/tex]×[tex]\frac{4}{3} =1[/tex]

We need to multiply the 4 1/2 ounces by 4/3 too

[tex]4\frac{1}{2}[/tex]×[tex]\frac{4}{3} =6[/tex]

4 1/2 ounces per 3/4 miles

6 ounces per 1 mile

Answer:

Step-by-step explanation:

Let the unknown number be x

[tex]4 \frac{1}{2} \: \: ounces = \frac{3}{4} \: \: miles \\ x = 1 \: \: mile[/tex]

Now simply use cross multiplication to solve it

[tex]4 \frac{1}{2} \times 1 = \frac{3}{4} x \\ \frac{9}{2} \times 1 = \frac{3}{4} x \\ \frac{9}{2} = \frac{3x}{4} \\ [/tex]

Now make x as the Subject

[tex] \frac{9}{2} = \frac{3x}{4} \\ \frac{9 \times 4}{2 \times 3} = x \\ \frac{36}{6} = x \\ 6 = x[/tex]

So the answer is

Answer:

Yes, SAS Theorem

Step-by-step explanation:

The triangles are congruent because of SAS Theorem that states that if two triangles have two sides and the angel in between them congruent the triangles are congruent.

JK≅NM (Side) because the sides have the same measure 74in. they are ≅

∡J≅∡M (Angle) because the angles have same measure 37° they are ≅

JL≅PM (Side) because the sides have the same measures 46in. they are ≅

Answer:

Choice D: 6 - r - 6 = - 24 - 6

Step-by-step explanation:

Equation is that sum of 6 and r is -24.

Thus;

6 + (-r) = - 24

6 - r = - 24

To isolate r in this equation, we will subtract 6 from both sides to get;

6 - r - 6 = - 24 - 6

Thus,option D is correct

Answer:

1. 2.19 cm

2. 30.2m

3. 2.65 cm

4. 9.33cm

5. 14.2 mm

6.497000km²

Step-by-step explanation:

Use the pi button on a calculator and give answers to 3's.f.

1. A circle has an area of 15 cm². Find its radius.

Area of a circle = πr²

15cm² = π × r²

r² = 15cm²/π

r² = 4.7746482927568605

r = √(4.7746482927568605)

r = 2.1850968612 cm

Approximately to 3 s.f ≈ 2.19 cm

2. A circle has a circumference of 190 m. Find its radius.

The circumference of a circle = 2πr

C = 190m

Hence:

190m = 2πr

r = 190m/2π

r = 30.239439187m

Approximately to 3 s.f = 30.2m

3. Find the radius of a circle of area 22 km².

Area of a circle = πr²

22km² = π × r²

r² = 22km²/π

r² = 7.002817496

r = √(7.002817496)

r = 2.6462837142 cm

Approximately to 3 s.f ≈ 2.65 cm

4. Find the radius of a circle of circumference 58.6 cm.

The circumference of a circle = 2πr

C = 58.6cm

Hence:

58.6cm = 2πr

r = 58.6cm/2π

r = 9.3264796652cm

Approximately to 3 s.f = 9.33cm

5. A circle has an area of 16 mm². Find its circumference.

Step 1

Find the radius

Area of a circle = πr²

16 mm² = π × r²

r² = 16 mm²/π

r² = 5.092958178940651

r = √(5.092958178940651)

r = 2.2567583342mm

Circumference of a circle = 2πr

Circumference = 2 × π × 2.2567583342

= 14.179630807mm

Approximately to 3 s.f ≈ 14.2 mm

6. A circle has a circumference of 2500 km. Find its area.

Step 1

Find the radius

The circumference of a circle = 2πr

C = 2500km

Hence:

2500km = 2πr

r = 2500km/2π

r = 397.88735773km

Area of a circle = πr²

Area of the circle = π ×(397.88735773km)²

Area of the circle = 497359.19716km²

Approximately to 3 s.f = 497000km²

Answer:

x = 6

y = 15

Step-by-step explanation:

We can find the value for x and y using similarity ratio

8/12 = 10/y cross multiply expressions

8y = 120 divide both sides by 8

y = 15

12/(x+12) = 10/15

180 = 10x + 120 subtract 120 from both sides

60 = 10x divide both sides by 10

6 = x

Step-by-step explanation:

Angles in a triangle add up to 180° and angles on a straight line add up to 180° with this information we can solve this problem.

180° - 95° = 85°

Now you have two of the angles, which means all you have to do to find the x is add your two angles up and take them away from 180°.

85° + 60° = 145°

180° - 145° = 35°
