hope this helps good luck

Asserting a cause - and - effect relationship with highly correlated variables may sometimes be misleading due to the presence of a possible lurking or confounding variable.

Lurking variables cause unintended or spurious association between correlated variables. In the scenario described, a possible confounding variable may be weariness or Fatigue which whereby the mother finds it easier to bottle feed as they have become psychologically disturbed and are prone to be more receptive during these period.

Hence, fatigue is a possible lurking variable in this scenario.

Answer: False but true

Step-by-step explanation: This question is all about slope. Slope is rise over run (y/x).

Plant 1:

Plant one has a rate of change of 1 for x. You see how it's going up by 1. For y, it's going up by three, which means that the slope is 3/1, which is three. Three is not equal to six.

Plant 2: follow the points that touch the x and y intersections (my teacher calls them "pretty points"). You see that the slope is 1, because it's going up and right by 1, so 1/1.

Although the measurements are wrong, the statment is true, because 3>1.

Answer:

x+5·-2=6

Step-by-step explanation:

Since expression = 3A + 2B                             [subsitute in values of A&B]

       ⇒                  = 3(r – 2) + 2(r² – 4r + 5)     [expnad the brackets]

                            = 3r - 6 + 2r² - 8r + 10           [group like terms ins stan. form]

                            = 2r² - 8r +  3r + 10 - 6         [simplify like terms]

                            = 2r² - 5r + 4

Note:

Standard form is ax² + bx + c  (where x is any variable, in this case 'r', and a,b,c are the coefficients)

doing the cumulative. have a good day or night

The initial value is $6 which shows the cost of the catalog.

The number of observations in a data set that are above (or below) a specific value can be found using cumulative frequency. A frequency distribution table, which can be created using stem and leaf plots or directly from the data, is used to compute the cumulative frequency.

We have the table

x     y

1      $10

2      $14

3       $18

4       $22

Now, to find the initial value we have to calculate the Cumulative Frequency as

x       y           CF

1      $10         10

2      $14         4

3       $18        4

4       $22       4

So, the initial value is

=10-4

= 6

The time that rocket will hit ground is 8.196 seconds.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. First, there must be a term other than zero in the coefficient of x² (a ≠ 0) for an equation to be a quadratic equation.

Given equation y = -16x² + 121x + 83

let y be the from ground and x be the time,

the time when rocket hit ground y = 0

-16x² + 121x + 83 = 0

solving using quadratic formula

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

here a = -16, b = 121 and c = 83

[tex]\sqrt{b^{2} - 4ac}[/tex] = [tex]\sqrt{121^{2} - 4(-16)(83) }[/tex]

= [tex]\sqrt{14641 + 5312}[/tex] = 141.25

x = -(-121 + 141.28)/32 = -0.633

x = -(-121 - 141.28)/32

x = 8.196 second

Hence the time is 8.196 seconds.

Answer:

[tex]-\frac{41}{36}[/tex]

Step-by-step explanation:

To add or subtract fractions, we need to make their denominators equal. To do so, we find the Least Common Denominator (LCD), then rewrite the fractions in the equation with that denominator.

The LCD of 9 and 12, the denominators, is 36 because [tex]9*4=36[/tex] and [tex]12*3=36[/tex].

Thus:

[tex]-\frac{5*4}{9*4} =-\frac{20}{36}[/tex] and [tex]-\frac{7*3}{12*3} =-\frac{21}{36}[/tex]

Now, add the fractions together.

[tex]-\frac{20}{36} -\frac{21}{36} =-\frac{20+21}{36} =-\frac{41}{36}[/tex]

Thus, the answer is [tex]-\frac{41}{36}[/tex].

Answer:

3 dimes

Step-by-step explanation:

Part A: 0.10x + 0.25 = 0.80 (dimes are 10 cents or 0.10 dollars, quarters are 0.25 dollars)

Part B: Plug in what you DO know and solve the one you DON’T:

0.10x + 0.25(2) = 0.80

0.10x + 0.50 = 0.80. Subtract 0.50 from both sides:

0.10x = 0.30 (Divide both sides by 0.10)
