The statement that best describes the correlation among the data is this: D. There is a strong correlation in which the amount collected decreased as time increased.

In determining the coefficient relationship between two variables, it is important to note that a coefficient 0f 0.7 and above is considered strong. In the given data, we see that the correlation coefficient was between 0.7 and -1.

This means that there is strong evidence to indicate that the amount of material collected decreased as time went by.

Answer:

Dataset 2

Step-by-step explanation:

The Coefficient of variation is the ratio of the standard deviation and the population mean.

Data Set 1: 2 = 12 and s = = 7

Data Set 2: 2

0.12 and s

= 0.3.

Coefficient of variation = (standard deviation / mean) * 100%

Dataset 1:

Standard deviation = 7 ; mean = 12

Coefficient of variation = (7 / 12 ) * 100% = 0.5833 = 58%

Dataset 2:

Standard deviation = 0.3 ; mean = 0.12

Coefficient of variation = (0.3 / 0.12) * 100% = 2.5 * 100% = 250

Hence dataset 2 varies the most with a greater value of variation Coefficient.

Answer:

d = [tex]\pi[/tex]

e = [tex]-\sqrt{8}[/tex]

f = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

D is equal to pi because pi is 3.1415... Therefore we need a point that is a little more than -3 and that is point d.

[tex]-\sqrt{8}[/tex] is roughly equal to -2.8 because 3 * 3 = 9 so that is too much, and 2 * 2 = 4 is too little so it has to be between -2 and -3. Therefore the point is e.

For 3/2 it has to be less than 2 because 2 cannot go into 3 more than once. The point would then be point f.

Answer:

im pretty sure you tried to say

Write 2^60 as an exponent with a base of:

a) 8

b) 16

c) 32

the answer is :

8^20 (eight to the twentieth power)

[tex]2^{60}[/tex] is equivalent to [tex]16^{15}[/tex].

We can rewrite the expression by means of the following power property, that is to say:

[tex]a^{b\cdot c} = (a^{b})^c[/tex], [tex]a, b, c\in \mathbb{N}[/tex] (1)

Where [tex]a[/tex] and [tex]a^{b}[/tex] are bases.

If we know that [tex]a = 2[/tex] and [tex]b\cdot c = 60[/tex], then the equivalent expression is:

[tex]2^{60} = 2^{4\cdot 15} = (2^{4})^{15} = 16^{15}[/tex]

Hence, [tex]2^{60}[/tex] is equivalent to [tex]16^{15}[/tex].

The side QR is the shortest side.

Option A is the correct answer.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

We can use the fact that in a triangle, the side opposite the smallest angle is the shortest side.

So we need to determine which angle is the smallest.

Now,

In ΔQRS,

m∠Q = 63º, m∠R = 70°, and m∠S= 47°

Now,

m∠S= 47° is the smallest.

So,

QR is the side opposite to m∠S.

Thus,

QR is the shortest side.

Step-by-step explanation:

THE ANSWER IS D, 2/7 x 28

Answer:

So i found the teacher notes after hours of looking here are the exact answers so i would recommend changing the wording.

Part A: Ordered pairs in the form (mb, kmh): (1,000, 100) and (960,180) Let X be the barometric pressure and Y be the wind speed.

Slope= (180-100)

          ----------------    = -2

          (960-1000)

Formula: y=-2(x-1000)+100

Part B: y=-2(980-1000)+100=140

140 kmh is reasonable. Because 980 mb is halfway between 960 mb and 1000 mb, we should expect a wind speed halfway between 180 kmh and 100 kmh.

Part C: The wind speed intercept is (0,2100) [or (2100,0) if written that way.] This means that when brometric pressure is 0 mb, then the wind speed would be 2100 kmh. However in the context of real weather, this is an impossible situation.

Part D: The slope means that every decrease of 2 kmh in wind speed corresponds to a 1 mb increase in barometric pressure.

Answer:

Answer:

x = 7

AB = 7

BC = 7

Step-by-step explanation:

AB = BC cuz it's an isosceles triangle

In the given isosceles triangle x is 7 units and AB ≅ BC is also of 7 units.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

As the triangle has two equal sides we can equate two expressions to find x.

∴ 2x - 7 = 4x - 21.

- 2x = - 14.

2x = 14.

x = 7.

AB = 2(7) - 7.

AB = 14 - 7.

AB = 7.

BC will also be of 7 units as AB ≅ BC.

If there are 3 boys for every 4 girls in a class, there would be 12 boys because 16 ÷4 us 4, and 4×3 is 13.

Answer:

15

Step-by-step explanation:

First we need to find the length of BC and for that we gonna use Pysagoras theorem

10^2 + (2√11)^2 = |BC|^2

√144 = |BC|^2

12 = BC Now we will use this to find the value of x

x^2 = 12^2 + 9^2

x^2 = 144 + 81

x^2 = 225

√x^2 = √225

x = 15

Answer:

The value of x is 15 cm.

Step-by-step explanation:

There are two triangles in the diagram that share a common side.

The triangles are:

ABC and BDC

First we have to find the third side of BDC so that we can use it to find the value of x.

The triangle is a right angled triangle so Pythagoras theorem can be used to find the third side.

In the triangle

[tex]Base = BD =10cm\\Hypotenuse = BC = ?\\Perpendicular = CD = 2\sqrt{11}cm[/tex]

Pythagoras theorem is given as:

[tex](Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\BC^2 = BD^2 + CD^2\\BC^2 = (10)^2 + (2\sqrt{11})^2\\BC^2 = 100+(2^2 * 11)\\BC^2 = 100+(4*11)\\BC^2 = 100+44\\BC^2 = 144\\\sqrt{BC^2} = \sqrt{144}\\BC = 12cm[/tex]

Now for triangle ABC

[tex]Base = BC = 12 cm\\Perpendicular = AB = 9 cm\\Hypotenuse = AC = x\\[/tex]

Using Pythagoras theorem

[tex]AC^2 = BC^2+AB^2\\x^2 = (12)^2 + (9)^2\\x^2 = 144+81\\x^2 = 225\\\sqrt{x^2} = \sqrt{225}\\x = 15cm[/tex]

Hence,

The value of x is 15 cm.
