Answer:

BC / 8 = sin 35° by definition.

Step-by-step explanation:

Using a calculator, it is found that the correlation coefficient for this data is given by:

B. -0.901.

To find the coefficient, which has symbol r², we input in a calculator the values of x and the values of y, hence:

r² = -0.901.

Which means that option B is correct.

Answer:

$4,915.2

Step-by-step explanation:

(20% of 12,000 = 2,400 | 12,000 - 2,400 = 9,600)

(20% of 9,600 = 1,920 | 9,600 - 1,920 = 7,680)

(20% of 7,680 = 1,536 | 7,680 - 1536 = 6,144)

(20% out if 6,144 = 1,228.8 | 6,144 - 1,228.8 = 4,915.2)

Answer:

PQ = 6 units

Step-by-step explanation:

note that the y- coordinates of P and Q are both - 7

then PQ is the difference in the x- coordinates, that is

PQ = | 7 - 1 | = | 6 | = 6

or PQ = | 1 - 7 | = | - 6 | = 6

volume: volume of cone is 1/3πr^2h

radius is 2

height is 6

plug into equation: 1/3π(2)^2*6=about 2.55 or 8π

surface area: surface area of cone is πrs+πr^2 where s is slant height.

to find slant height use pythagorean theorem: √(2^2+6^2)=√40

radius: 2

height:6

slant height: √40

plug into equation: π(2)(√40)+π(2^2)=about 52.30 or 4√10π+4π

Answer:

4080 cm³

Step-by-step explanation:

Figure is of a cuboid

Given length (l) = 30cm

breadth (b) = 17cm

height (h) = 8cm

Volume of cuboid = l.b.h

= 30 × 17 × 8

= 4080 cm³

length= 9 cm

width= 5 cm

height= 4 cm

the surface area of the given cuboid.

[tex]s.a = 2(lb + bh + lh)[/tex]

[tex]s.a = 2((9 \times 5) + (5 \times 4) + (9 \times 4))[/tex]

[tex]s.a = 2(45 + 20 + 36)[/tex]

[tex]s.a = 2 \times 101[/tex]

[tex]s.a = 202 \: {cm}^{2} [/tex]

therefore, the surface area of the given cuboid is 202 square centimeters.

Answer:

16 ft^2

Step-by-step explanation:

The area of a triangle is calculated by multiplying its height and base then dividing it by 2

Height of this triangle is given as 4ft

the base is 8ft

4*8/2 = 16 the area is given is square units so the answer is 16 ft^2

Step-by-step explanation:

The equation of the line that passes through the points (7, 450) and (14, 401) is y + 7x = 499

The equation of a line  can be represented as follows:

y - y₁ = m(x - x₁)

where

Therefore, (7, 450)(14, 401)

m = 401 - 450 / 14 - 7 = -49 / 7 = -7

Therefore, using (7, 450)

y - 450 = -7(x - 7)

y - 450 = -7x + 49

y + 7x = 49 + 450

y + 7x = 499

Answer:

Answer is 5

Step-by-step explanation:

Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

The measure of angle ∠CAB will be 68 degrees and the measure of angle ∠CAD will be 22 degrees.

It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

In the circle below, stack AD with a bar on top is diameter and stack AB with a left-right arrow on top is tangent at A. Suppose m stack ADC with over parenthesis on top equals 224 degrees.

Then the measures of m angle ∠CAB and m angle ∠CAD will be  

Then we have

We know that

mADC = mAD + mDC

  224° = 180° + mDC

 mDC = 44°

Then we know the theorem, A chord's degree in the centre is double that of the chord's degree at the perimeter. Then we have

2 ∠CAD = 44°

  ∠CAD = 22°

Then the angle ∠CAB and angle ∠CAD are complementary angles. Then we have

∠CAB + ∠CAD = 90°

   ∠CAB + 22° = 90°

            ∠CAB = 68°
