On the last day of vacation, the Hernandez family drove 252 miles from a state park to their home. That drive covered 35% of the total distance the family traveled during their vacation. What is the total distance the Hernandez family traveled during their vacation
Answers
Answer:
720 miles
Step-by-step explanation:
We are given a distance and a fraction of the total that it represents. This lets us write the relation ...
252 = 0.35D . . . . . . where D is the total distance traveled
252/0.35 = D = 720 . . . . divide by the coefficient of D
The Hernandez family traveled 720 miles during their vacation.
Starbucks Coffee Co. Uses a data-based approach to improving the quality and customer satisfaction of its products. When survey data indicated that Starbucks needed to improve its package-sealing process, an experiment was conducted to determine the factors in the bag-sealing equipment that might be affecting the ease of opening the bag without tearing the inner liner of the bag. (Data extracted from L. Johnson and S. Burrows, "For Starbucks, Itâs in the Bag," Quality Progress, March 2011, pp. 17â23. ) One factor that could affect the rating of the ability of the bag to resist tears was the plate gap on the bag-sealing equipment. Data were collected on 19 bags in which the plate gap was varied. The results are stored in Starbucks.
a. Construct a scatter plot.
b. Assuming a linear relationship, use the least-squares method to determine the regression coefficients b0 and b1.
c. Interpret the meaning of the slope, b1, in this problem.
d. Predict the mean tear rating when the plate gap is equal to 0.
e. What should you tell management of Starbucks about the relationship between the plate gap and the tear rating?
Answers
When there's a linear relationship, the least-squares method to determine the regression coefficients b0 and b1 will be y = 0.750 + 0.50x.
How to interpret the slope?The meaning of the slope, b1, in this problem is the coefficient of x which is the slope. Here, b1 = 0.50. It implies that one unit change in x will be 0.5 unit change in y.
To predict the mean tear rating when the plate gap is equal to 0 goes thus:
y = 0.75 + (0.05 × 0)
y = 0.75 + 0
y = 0.75
Lastly, the relationship between the plate gap and the tear rating is a positive one.

1000x+27x+5.5=9236
Answers
Answer:
x = 8.98782862707
Step-by-step explanation:
Base on the given we can infer that we are solving for x:
Given equation:
1000x+27x+5.5=9236
Combine similar terms
1027x + 5.5 = 9236
Subtract both side by 5.5
1027x + 5.5 = 9236
-5.5 -5.5
-------------------------------------
1027x = 9230.5
Now divide both sides by 1027x
9230.5 / 1027
x = 8.98782862707

What is an Expression?
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The difference between the squares can be written as,
[tex]a^2-b^2=(a+b)(a-b)[/tex]
The expression that will result in the difference in the squares will be
[tex](7x+4)(7x-4)=(7x)^2-(4)^2[/tex]
Thus, the expression that will result in the difference in the squares is (7x+4)(7x-4).

y+3=-4(x-1)y+3=-4x+4y=-4x+1Answer:
[tex]y=-4x+1[/tex]
Step-by-step explanation:
We have been given two points on the line, so:
[tex]\textsf{let}\:(x_1,y_1)=(-1,5)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(1,-3)[/tex]
Calculate the slope using the slope formula:
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-3-5}{1-(-1)}=-4[/tex]
From inspection of the graph, it appears that the y-intercept (where the line crosses the y-axis) is at (0, 1). However, just to be sure, use the point-slope form of linear equation.
Point-slope form of linear equation: [tex]y-y_1=m(x-x_1)[/tex]
(where m is the slope and (x₁, y₁) is a point on the line)
[tex]\implies y-5=-4(x-(-1))[/tex]
[tex]\implies y-5=-4x-4[/tex]
[tex]\implies y=-4x+1[/tex]
Therefore, the equation of the line in slope-intercept form is:
[tex]y=-4+1[/tex]

To find the area of a circle, take π x 2 x radius.
true or false
Answers
Answer:
That statement is true, but you do not always need the two.
Let's say that we had a problem, given the radius is 5, and we have to find the diameter.
First step is to define A
[tex]A = \pi r^2[/tex]
Second, redefine r as the actual radius to avoid confusion.
[tex]r = 5[/tex]
Third, set up an equation with the given values where you are multiplying pi by the radius.
[tex]\pi r^2 = \pi *r^2[/tex]
Fourth but not least, get the actual value.
[tex]\pi * r^2 = 79[/tex] rounded to nearest whole number
