Step-by-step explanation:
doing the cumulative. have a good day or night
The initial value is $6 which shows the cost of the catalog.
What is Cumulative Frequency?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

Jackson has $1.50 in quarters and dimes. Let x represent the number of quarters and y represent the number of dime. Find the domain and range of this situation.
Answers
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)
x = 3

What is quadratic equation?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.

Answers
Answer:
8[tex]\frac{3}{5}[/tex] OR [tex]\frac{43}{5}[/tex]
Step-by-step explanation:
The total amount of rice that the chef bought is 8 6/10
The chef brought 3/2 pounds of white rice
The chef also brought 71/10 pounds of brown rice
Therefore the total amount can be calculated as follows
3/2 + 71/10
= 15 + 71/10
= 86/10
= 8 6/10
Hence the total number of rice bought by the chef is 8 6/10

An article in a women's magazine says that women who choose to nurse their babies feel warmer and more receptive toward the infants than mothers
who bottle-feed. The author concludes that nursing has desirable effects on the mother's attitude toward the child. Explain why asserting a cause-and-effect relationship based on this information is suspect, and give another plausible explanation for the association between the decision to bottle-feed or nurse and mothers’ attitudes toward their children.
Answers
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.

[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].
