Which best describes the association between variables x and y?

B. Strong Negative

C. Weak Positive

D. Weak Negative

The two quantities we want to analyze are

[tex] 3254 \times 105 + 12 [/tex]

and

[tex] 1256 \times 105 [/tex]

We wonder if the first if 12 times the second. Let's compute them both to begin with:

[tex] 3254 \times 105 + 12 = 341682 [/tex]

and

[tex] 1256 \times 105 = 131880 [/tex]

So, the question is: is 341682 twelve times 131880? The check is very simple:

[tex] 131880 \times 12 = 1582560>341682 [/tex]

So the answer is no

Answer:

16 dollars.

Step-by-step explanation:

Given that selling price of a back pack after reduced by 30% is 11.20 dollars.

We have to find the original price of the back pack.

Let original price = 100

Reduced %          =  30

Selling price         = 70

70 dollars is equivalent to selling price of 11.20 $

100 dollars is equivalent to selling price of 100(11.2)/70 = 16 $

i.e. original price of back pack is 16 dollars.

I would say 67°F would be the right answer.

(1)

we are given

U is the midpoint of RS

and we have

[tex]RU=12[/tex]

so, we can use formula

[tex]RS=2RU[/tex]

we can plug values

[tex]RS=2\times 12[/tex]

[tex]RS=24[/tex]............Answer

(2)

V is the midpoint of ST

so, we get

[tex]SV=VT[/tex]

now, we can plug values

[tex]2x=11[/tex]

divide both sides by 2

[tex]x=5.5[/tex].........Answer

(3)

now, we can find y

W is the midpoint of TR

so, we get

[tex]RW=WT[/tex]

we can plug value

[tex]15.9=3y[/tex]

divide both sides by 3

[tex]y=5.3[/tex]

(4)

we can see that

triangles URW and RST are similar

so, their sides ratios must be equal

so, we get

[tex]\frac{RW}{RT} =\frac{UW}{ST}[/tex]

we can plug values

[tex]\frac{15.9}{2\times 15.9} =\frac{UW}{2VT}[/tex]

[tex]\frac{15.9}{2\times 15.9} =\frac{UW}{2\times 11}[/tex]

[tex]UW=22\times \frac{15.9}{2\times 15.9}[/tex]

[tex]UW=11[/tex]...........Answer

(5)

we can see that

triangles SUV and RST are similar

so, their sides ratios must be equal

so, we get

[tex]\frac{SU}{SR} =\frac{UV}{RT}[/tex]

now, we can plug values

[tex]\frac{12}{2\times 12} =\frac{UV}{2\times 15.9}[/tex]

[tex]UV=2\times 15.9\times \frac{12}{2\times 12}[/tex]

[tex]UV=15.9[/tex].............Answer

1. The length of RS is 24 units.

2. The value of [tex]x[/tex] is 5.5.

3. The value of [tex]y[/tex] is 5.3.

4. The length of UW is 11.

5. The length of UV is 15.9.

According to the given figure-

[tex]\triangle RST \sim \triangle URW[/tex]

1. U is the mid-point of RS so, the length of UR and US are equal.

Hence, the length of RS is 24 units.

2. V is the mid-point of ST so, the length of VS and VT are equal.

So,

[tex]2x=11\\x=\dfrac{11}{2}\\x=5.5[/tex]

Hence, the value of [tex]x[/tex] is 5.5.

3. W is the mid-point of RT so, the length of WR and WT are equal.

So,

[tex]3y=15.9\\y=\dfrac{15.9}{3}\\y=5.3[/tex]

Hence, the value of [tex]y[/tex] is 5.3.

4. As, [tex]\triangle RST \sim \triangle URW[/tex]

So, the length of the sides is proportional.

[tex]\dfrac{RT}{RW}=\dfrac{ST}{UW}\\\dfrac{2\times 15.9}{15.9}=\dfrac{11\times 2}{UW}\\UW=11[/tex]

Hence, the length of UW is 11.

5.  As, [tex]\triangle RST \sim \triangle URW[/tex]

So, the length of the sides is proportional.

[tex]\dfrac{SU}{SR}=\dfrac{UV}{RT}\\\dfrac{12}{2\times 12}=\dfrac{UV}{2\times 15.9}\\UV=15.9[/tex]

Hence, the length of UV is 15.9.

B) (4,24)

This is because you turn one of the equations you make, let's use x+4y=100, and turn it into y=mx+b form. This turns into y=(-x/4) +25 and if you plug in the number 4 as your x you get 24.

The Algebra expression a/b + c²d with the given values (a=6, b=3, c=4, d=5) evaluates to 82. This involves steps of squaring, multiplication, division, and finally addition.

In order to evaluate the expression a/b + c²d, we substitute the given values into the expression. For this problem, the values given are a=6, b=3, c=4, and d=5. Thus, the expression becomes: 6/3 + (4)²(5).

First, we perform the operations in the parenthesis, which is 4 squared, or 4*4, which gives us 16.

Next, we multiply this result by d, which is 5. Therefore, 16*5 gives us 80.

Finally, we perform the division operation: a/b, that is 6 divided by 3, which equals 2.

Adding these two results together, 2 + 80, we get our final answer, which is 82.

Answer:

√357

Step-by-step explanation:

multiply all three numbers together and since 357 cannot be simplified it stays as a radical

The radical form of √3 x √7 x √17 is √357.

When we have a number raised to a power that is less than one but greater than zero we call them surds and when we have numbers that have been raised by powers that are greater than one we call them indices.

Radical multiplications are the same as multiplying integers only we can not add radicals of different values under the square root.

∴ √3 × √7 × √17.

= √51 × √7.

= √357.

We can't simplify this more because the multiplication was of all prime numbers.

Problem 2

We can shift the K up 6 units to get what you see in the attached image below

Answer:

Option A is the correct answer.

Explanation:

 The given pyramid has 3 lateral triangular side as shown below.

 Base of triangle = 12 unit

 We need to find perpendicular.

  By Pythagoras theorem we have

            Perpendicular² = 10²-6²

           Perpendicular = 8 unit

So area of 1 lateral triangle = 1/2 x Base x Perpendicular.

                                             = 1/2 x 12 x 8 = 48 unit²

Area of lateral side = 3 x 48 = 144 unit²    

Option A is the correct answer.

Answer:

Temperature at 4 am is 66 degrees.

Step-by-step explanation:

First we have to count how many half an hour's are there from 6 pm to 4 am.

Number of hours from 6 pm to 4 am.  =  [tex]10[/tex] hours

Number of half an hours from 6 pm to 4 am.  = [tex]10*2[/tex]

                                                                           =[tex]20[/tex]

It is given that temperature drops [tex]1\frac{1}{4}[/tex] degrees every half an hour.

Therefore,

Temperature drop in 20 half an hours = [tex]1\frac{1}{4}*20[/tex] degrees

                                                                =[tex]\frac{5}{4} *20[/tex] degrees

                                                                =[tex]25[/tex] degrees

Temperature drops 20 degrees from initial 86 degrees.

Therefore, temperature at 4 am = 86 degrees - 20 degrees

                                                      = 66 degrees

Remember that [tex] 40 = 2\cdot 2\cdot 10 [/tex].

So, dividing by 40 means dividing by 10, then by 2, then by 2 again.

So, we can go like this: let's divide by 10 first

[tex] 13 \div 10 = 1.3 [/tex]

Then, we divide by 2:

[tex] 1.3 \div 2 = 0.65 [/tex]

And by 2 again:

[tex] 0.65 \div 2 = 0.325 [/tex]

Answer:  the correct option is (C) (2, 5).

Step-by-step explanation:  We are given to use the substitution method to solve the following system of equations :

[tex]2y+4x=18~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\2y-3x=4~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]

Dividing equation equation (i) on both sides by 2, we have

[tex]\dfrac{2y+4x}{2}=\dfrac{18}{2}\\\\\Rightarrow y+2x=9\\\\\Rightarrow y=9-2x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)[/tex]

Substituting the value of y from equation (iii) in equation (ii), we get

[tex]2(9-2x)-3x=4\\\\\Rightarrow 18-4x-3x=4\\\\\Rightarrow 18-4=4x+3x\\\\\Rightarrow 14=7x\\\\\Rightarrow x=\dfrac{14}{7}\\\\\Rightarrow x=2.[/tex]

So, from equation (iii), we get

[tex]y=9-2\times2=9-4=5.[/tex]

Thus, the required solution of the given system is (x, y) = (2, 5).

Answer:

b is the base of function which help us to determine the growth rate and Also tells the multiplicity of fishes .

Step-by-step explanation:

Exponential Function: [tex]ab^x[/tex]  --1

a = initial value (the amount before measuring growth or decay)

b>1 growth

b<1 decay

The growth "rate" (r) is determined as b = 1 + r.

The decay "rate" (r) is determined as b = 1 - r

After observing the population growth over a few weeks, the exponential function :

[tex]P(t) = 7(2)^t[/tex]

Comparing it with 1

b  = 2

Since b >1

So, it is the growth function

So, The growth "rate" (r) is determined as b = 1 + r.

2 = 1+r

r = 1

Hence growth rate is 1

So, b is the base of function which help us to determine the growth rate and Also tells the multiplicity of fishes .
