Question 15: (5 points)
Svetradugi [14.3K]

Answer:

(4,7)

Step-by-step explanation:

Given

2x - 3 < y

(x,7)

Required

Find one possible value of x

From the given parameters;

(x,7) is a possible solution of 2x - 3 < y where y= 7

Substitute 7 for y

2x - 3 < 7

Add 3 to both sides

2x - 3 + 3 < 7 + 3

2x < 10

Divide both sides by 2

2x/2 < 10/2

x < 5

The result of the inequality implies that x is less than 5; So, the possible values of x is all real numbers less than 5;

Having said that;

(4,7) is one possible coordinate of 2x - 3 < y

Bivariate Data problem. Image attached. <br><br> A. 5.967<br> B. 6.671<br> C. 9.352<br> D. 9.338
Fed [463]

Answer:

A

Step-by-step explanation:

s_x  is the standard deviation of x.

The standard deviation is gotten by:

1. find the average of x-values (add up all the values and divide by number of numbers, which is 5)

2. subtract the average, x bar, from each of the values, square it,  and add up the difference

3. Divide that final answer by n, which is 5

4. Take the square root of the answer

<em>Now, let's find the average (x bar):</em>

<em>x bar = \frac{2+6+9+14+19}{5}=10</em>

<em />

<em>Doing steps 2 & 3 together:</em>

<em>\frac{(2-10)^2+(6-10)^2+(9-10)^2+(14-10)^2+(19-10)^2}{5}\\=35.6</em>

<em />

<em>Doing step 4:</em>

<em>\sqrt{35.6} =5.967</em>

<em />

Correct answer is A

Find four consecutive integers whose sum is 682.
Vitek1552 [10]
Because they're consecutive, it means that the first one is x, the second one is x+1, the third one is x+2 (x+1+1), and the fourth one is x+3. Because we're given that the sum of all of them is 682, just add all of them together:
x+(x+1)+(x+2)+(x+3)=682
x+x+x+x+1+2+3=682
4x+6=682
4x+6-6=682-6
4x=676
x=676/4
x=169
Thus, the consecutive integers are: 169, 170, 171, 172
