What is the equation of the line?
Answer:
[tex]y = \frac{-7}{3}x -12[/tex]
Step-by-step explanation:
Point-slope form is [tex]y-y_1= m (x-x_1)[/tex]. The [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] have to be substituted for with real values in order to make an equation of a line. From there, you can isolate [tex]y[/tex] to turn it into slope-intercept form.
1) First, let's find the slope of the line, which is represented by the variable [tex]m[/tex]. Use the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], to find the slope. [tex]x_1[/tex] and [tex]y_1[/tex] are the x and y values of one point, [tex]x_2[/tex] and [tex]y_2[/tex] are the x and y values of another point. For this problem, let's use the given points (-3, -5) and (-6, 2):
[tex]\frac{(2)-(-5)}{(-6)-(-3)} \\= \frac{2+5}{-6+3} \\= \frac{7}{-3}[/tex]
Thus, the slope is [tex]\frac{7}{-3}[/tex].
2) Now that we have the slope, let's substitute it into the point-slope formula. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point that the line intersects so you could either use (-3, -5) or (-6,2), but for this answer, I used (-6,2). (The answer will always be the same no matter which point you choose.) Substitute these values then isolate y to put it in slope-intercept form:
[tex]y-(2) = \frac{-7}{3} (x-(-6))\\y -2 = \frac{-7}{3} (x+6)\\y-2 = \frac{-7}{3}x-\frac{42}{3} \\y -2 = \frac{-7}{3}x-14\\y = \frac{-7}{3}x-12[/tex]
So, [tex]y = \frac{-7}{3}x -12[/tex] is the answer.
What is 9.25% tax of $27.26?
Answer:
$29.78
Step-by-step explanation:
1. make the % into a decimal
9.25% = 0.0925
2. multiply amount by the decimal to get the tax amount
$27.26 × 0.095 = $2.52
3. take the original amount and add the tax to get your final total
$26.27 + $2.52 = $29.78

How many squares does Erica knit by the end of the day on Friday?
Erica knits
squares by the end of the day on Friday.
Answer:
35
Step-by-step explanation:
16+ (4x4[4 days a week])
4x4=16
16+19
10+10=20
6+9=15
20+15=35
so therefore you're answer is 35

As part of an experiment, Janelle spins a multicolored spinner 100 times and concludes that the probability of the arrow landing on orange is an unlikely event. If Janelle’s conclusion is true, which of these could be the probability of the event?
(A): 0
(B): 0.3
(C): 0.5
(D): 1
0.3, because 1 is certain, 0 is impossible, 0.5 is likely
Which of the following two-dimensional shapes can be rotated to create a sphere?
Triangle
Square
Circle
Ellipse
Answer: C. Circle
Step-by-step explanation: i got it right good luck
When the circle is rotated then it forms the sphere. Then the correct option is C.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
Whenever the 2D shape is rotated we get 3D solid.
A. Triangle - when the triangle is rotated then it forms the cone.
B. Square - when the square is rotated then it forms the cylinder.
C. Circle - when the circle is rotated then it forms the sphere.
D. Ellipse - when the ellipse is rotated then it forms the flat sphere.
Thus, the correct option is C.

Through process design improvements, the process standard deviation can be reduced to 0.04. Assume the process control remains the same, with weights less than 9.88 or greater than 10.12 ounces being classified as defects. Calculate the probability of a defect.
Complete Question
Assume a production process produces items with a mean weight of 10 ounces.
Through process design improvements, the process standard deviation can be reduced to 0.04. Assume the process control remains the same, with weights less than 9.88 or greater than 10.12 ounces being classified as defects. Calculate the probability of a defect.
Answer:
0.0027
Step-by-step explanation:
We solve using the formula for z score
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 10 ounces
σ is the population standard deviation = 0.04 ounces
Hence:
For x < 9.88 ounces
z = 9.88 - 10/0.04
z = -3
Probability value from Z-Table:
P(x < 9.88) = 0.0013499
For x > 10.12 ounces
z = 10.12 - 10/0.04
z = 3
Probability value from Z-Table:
P(x<10.12) = 0.99865
P(x>10.12) = 1 - P(x<10.12)
= 0.0013499
The probability of a defect is calculated as:
P(x = 10.12) or P(x = 9.88)
P(z = 3) or P(z = -3)
= 2P
= 2(0.0013499)
= 0.0026998
Approximately = 0.0027
Therefore, the Probability of the defect is 0.0027

A hybrid car with a 9.80 gal tank consumes gasoline at a rate of 54.1 miles/gal. How many liters of gasoline will be consumed traveling 132 km? (hint: please feel welcome to use a table of useful conversion factors).
The answer is ______ liters.
9514 1404 393
Answer:
about 5.74 liters
Step-by-step explanation:
The conversion factor is about 0.42514370743 km/liter for each mile per gallon. Then ...
(132 km) / ((54.1 mi/gal)×(0.42514370743 km/L)) ≈ 132/23.00 L = 5.74 L
_____
The exact conversion factors are ...
1 mi = 1.609344 km
1 gal = 3.785411784 L
The conversion to from mi/gal to km/L is exactly 48000/112903.
Determine if the statement is true or false. Any linear system with more variables than equations cannot have a unique solution.
Answer:
True
Step-by-step explanation:
Suppose a system contains a large number of variables than equations, then there is a need to make assumptions of some values for the extra variables in order to solve the system. So, the assigning of these values can be done in several ways. Thus, the system cannot contain a unique solution.
Also, for a system of the linear equation:
[tex]AX = B[/tex] can have a unique solution if:
Augmented matrix(rank) = coefficient matrix(rank) = no. of variables.
Provided that there exist fewer equations and more variables,
Then;
coefficient matrix(rank) < no. of variables
Thus, the system cannot contain a unique solution.
