Answer:

5

Step-by-step explanation:

Let's solve your equation step-by-step.

−2k+7=−3

Step 1: Subtract 7 from both sides.

−2k+7−7=−3−7

−2k=−10

Step 2: Divide both sides by -2.

−2k/-2 = -10/-2

k=5

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.

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.

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.

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.

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

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

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.
