Answer:

Negative Association

Step-by-step explanation:

Answer:

B) negative association

D) linear association

Step-by-step explanation:

We are given a scatter plot which represents the relationship between the variable A and the variable B.

As you can see the values of the variable A increase, the values of the variable B decrease.

It is clearly shows the negative trend.

Also we can see the points not deviated much, the points looks to form a linear association.

So there must be two statements which associates with this scatter plot.

Explanation:

A. down

The -4 moves the y-intercept down from the origin to -4

Answer: Option A.

Step-by-step explanation:

The equation of the line in slope-intercept form is:

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

Where the slope is "m" and the intersection of the line with the y-axis is "b".

Given the function f(x) in the form [tex]f(x)=x[/tex], you can identify that:

[tex]m=1\\b=0[/tex]

This means that the line passes through the origin (0,0)

And from the function g(x) in the form [tex]g(x)=x-4[/tex], , you can identify that:

[tex]m=1\\b=-4[/tex]

This means that the line of the function g(x) and the line of the function f(x) have the same slope, but the line of g(x) passes through the point (0,-4)

Therefore, the graph of f(x) must be shifted 4 units down to produce the graph of g(x)

Answer:

x= 15/8

Step-by-step explanation:

we need to solve the equation to find the value of x by adding like terms and then finding the value of x.

[tex](\frac{1}{2})x+(\frac{3}{2})(x+1)-(\frac{1}{4})=5\\(\frac{1}{2})x + (\frac{3}{2})x + (\frac{3}{2}) - (\frac{1}{4}) = 5\\Adding\,\,like\,\,terms\,\\(\frac{(1+3)x}{2}) + (\frac{6-1}{4})=5\\(\frac{4x}{2}) + (\frac{5}{4})=5\\2x= 5- \frac{5}{4}\\2x = \frac{20-5}{4}\\2x= \frac{15}{4}\\x= \frac{15}{4*2}\\x= \frac{15}{8}[/tex]

The value of X is ratio of fifteen to eight. That is, x = 15/8

Algebraic equation comprises of unknown variables with equality sign.

To evaluate 1/2x+3/2(x+1)-1/4 = 5, Find the LCM in the left hand side.

[tex]\frac{x}{2}[/tex] + [tex]\frac{3(x+1)}{2}[/tex] - [tex]\frac{1}{4}[/tex] = 5

At the Left hand side, the L.C.M is 4

[tex]\frac{2x+6(x+1)-1 }{4} = 5[/tex]

Cross multiply

2x + 6x + 6 - 1 = 20

8x + 5 = 20

Collect the like terms

8x = 20 - 5

8x = 15

Make x the subject of the formula

x = 15/8

Therefore, x = 15/8 in the given algebraic equation.

Answer: Option D

Step-by-step explanation:

Add 4x² to both sides  of the equation:

[tex]16x+8+4x^2=-4x^2+4x^2\\4x^2+16x+8=0[/tex]

The Quadratic formula is:

[tex]x=\frac{-b\±\sqrt{b^2-4ac}}{2a}[/tex]

You can identify that in this case:

[tex]a=4\\b=16\\c=8[/tex]

Substitute into the Quadratic formula:

[tex]x=\frac{-16\±\sqrt{(16)^2-4(4)(8)}}{2(4)}[/tex]

 [tex]x_1=-0.58\\x_2=-3.41[/tex]

Therefore, the graph of the equation above intersect the x-axis in two points.

The answer is:

D. The parabola intercepts the x-axis in two points.

[tex]x_{1}=-0.59\\\\x_{2}=-3.41[/tex]

To find the parabola intercepts, we need to use the quadratic formula. The parabola intercepts with the x-axis, are also called roots or zeroes.

The quadratic formula states that:

[tex]x=\frac{-b+-\sqrt{b^{2}-4ac } }{2a}[/tex]

We are given the parabola:

[tex]16x+8=-4x^{2} \\[/tex]

Which is also equal to:

[tex]4x^{2}+16x+8=0[/tex]

Where,

[tex]a=4\\b=16\\c=8\\[/tex]

Then, substituting into the quadratic formula to find the roots of the parabola, we have:

[tex]x=\frac{-b+-\sqrt{b^{2}-4ac } }{2a}\\\\x=\frac{-16+-\sqrt{(16)^{2}-4*4*8 } }{2*4}=\frac{-16+-\sqrt{(256-128) } }{8}\\\\x==\frac{-16+-\sqrt{(256-128) } }{8}=\frac{-16+-\sqrt{(28 } }{8}\\\\x=\frac{-16+-\sqrt{128 } }{8}=\frac{-16+-(11.31) }{8}\\\\\\x_{1}=\frac{-16+(11.31) }{8}=-0.59\\\\x_{1}=\frac{-16-(11.31) }{8}=-3.41[/tex]

Hence,the parabola intercepts the x-axis in two points.

[tex]x_{1}=-0.59\\\\x_{2}=-3.41[/tex]

Step-by-step explanation:

Since Ground A has area 300 and maximum capacity is 25 tents, so each tent would take up area of  300/25 = 12 sq yards.

Since Ground B's tents should occupy same area as Ground A's tents (12 sq. yards), the maximum capacity of this tent (480 sq yd) would be:

480/12 = 40 pup tents

This is the maximum capacity.

Answer:

24 presents.

Step-by-step explanation:

First I did 36 multiplied by 6 and got 216. Then i divided 216 by 9 and got 24.

Answer: with 6 yards of ribbons we can wrap 24 presents.

Step-by-step explanation:

For each 9 inches of ribbons, we can wrap one present, then if we have 6 yards we have:

1 yard = 36 inches

then 6 yards is equal to 6*36 inches = 216 inches

now, in how many pieces of 9 inches we can divide the 216 inches?

this is:

N = 216/9 = 24

for each one of those 24 pieces of 9 inches we can wrap a present, this means that with 6 yards of ribbons we can wrap 24 presents.

The missing number is 3

Step-by-step explanation:

Let the missing number be y

20 + (y × 14) - 12 = 50

Opening the brackets;

20 + 14y - 12 = 50

Answer:

8904

Step-y-step explanation:

Answer:

The population of Linton is 8,904.

Step-by-step explanation:

To start out, they give you a ratio of 12:1, adding all the parts to get a whole would make this ratio 13:1.

Now, since the whole is 13, this means that 13 = 9,646 people.

Next we want to divide 9,646 by 13, this gives us 742.

X = 742

12x = 12 * 742 = 8,904

Answer:

The largest angle is 6x,and 6x=90

So, the measure of the largest angle is 90

Step-by-step explanation:

First, you create an equation by adding the three angles together and equal to 180,because a triangle has 180 degrees.

The result will be 15.If x=15 ,you need to plug it in.

the largest angle is 6x,So, 6.15=90

90 degrees

The problem states the measures of three angles of a triangle as 4x-1, 2x+1, and 6x. According to the basic theorem that the sum of the angles in a triangle is 180 degrees, if we add these angles together, and equate them to 180, we get the equation 4x - 1 + 2x + 1 + 6x = 180. Adding like terms simplifies this to 12x = 180, and dividing each side by 12 gives us x = 15. Therefore, the largest angle is 6x, which would be 6 * 15 = 90 degrees.

150 CASH

Step-by-step explanation:

if you do 25 down and 12 dollar for 11 month you pay 7 more dollars

Final answer:

The cost of financing the smartphone with a down payment and monthly payments would be $157.00, compared to a one-time cash payment of $150.00.

Explanation:

The question posed involves comparing the cost of purchasing a smartphone either with a one-time cash payment or financing it with a down payment followed by monthly payments. To calculate the total cost of the financing option, you add the down payment to the product of the monthly payment amount and the number of months for repayment. In this case, we use the following calculation: $25.00 down payment + ($12.00 per month × 11 months) = $25.00 + $132.00 = $157.00. The total cost when financing the smartphone would be $157.00, which is $7.00 more than the upfront cash payment of $150.00.

Answer:

3.52 × 10⁸

Step-by-step explanation:

Scientific notation is written in: Number that is in the ones place × 10^power.

Here, the number is 3.52, since 3 has the largest placement.

The power on the 10 should be the number of 0's on 352,000,000/3.52. That is 100,000,000. That number has 8 0's, so the power is to the 8th.

Putting that together, this number in scientific notation in 3.52 × 10⁸.

Answer:

11 degrees.

Step-by-step explanation:

"Angles T and U are a linear pair. Angle U measure (9x+6) and Angle T measures(6x+9). What is the value of x, in degrees?"

We know that a linear pair MUST add up to 180 degrees, therefore (9x+6)+(6x+9)= 180

Now for some algebra-

(9x+6)+(6x+9)= 180

6 and nine can both be divided by 3, so we will do that for simplicity:

((9x+6)+(6x+9)= 180)/3=

(3x+2)+(2x+3)=60

We will now separate the parenthesis, as they serve no purpose anymore.

(3x+2)+(2x+3)=60

3x+2+2x+3=60

Combine terms

5x+5=60

Take away the 5 to isolate the variables

5x+5=60

-5

5x=55

Divide by 5

5x=55

/5

x=11

The value of x is 11 degrees.
