Answer: No.

Step-by-step explanation: 4 and -1 are both tied to 1 in the map. A function can never have 2 values.

Write a linear equation in slope-intercept form. m=-3 and contains (0,2)
katen-ka-za [31]
<h3>Answer:</h3>

y=-3x-2

<h3>Solution:</h3>
  • We have a point that the line passes through and its slope.
  • Since the point has an x-coordinate of 0, this point is the line's y-intercept (2)
  • Slope-intercept form: y=mx+b
  • m -> slope
  • b -> y-intercept
  • Plug in the values:
  • y=-3x-2

Hope it helps.

Suppose that prices of a gallon of milk at various stores in one town have a mean of $3.91 with a standard deviation of $0.13. U
zhenek [66]

Answer:

The minimum percentage of stores that sell a gallon of milk for between $3.65 and $4.17 is of 75%.

Step-by-step explanation:

Chebyshev Theorem

The Chebyshev Theorem can also be applied to non-normal distribution. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

An in general terms, the percentage of measures within k standard deviations of the mean is given by 100(1 - \frac{1}{k^{2}}).

In this question:

We have a mean of $3.91 and a standard deviation of $0.13.

Using Chebyshev's Theorem, what is the minimum percentage of stores that sell a gallon of milk for between $3.65 and $4.17?

3.65 = 3.91 - 2*0.13

4.17 = 3.91 + 2*0.13

Within 2 standard deviations of the mean, so, by the Chebyshev's Theorem, the minimum percentage of stores that sell a gallon of milk for between $3.65 and $4.17 is of 75%.

What is the value of x that makes the equation
loris [4]

Answer:

\boxed {x = 19}

Step-by-step explanation:

Solve for the value of x:

3x - 4 = 15 + 2x

-Take 2x and subtract it from 3x:

3x - 4 - 2x = 15 + 2x - 2x

x - 4 = 15

-Add 4 to both sides:

x - 4 + 4 = 15 + 4

\boxed {x = 19}

So, the value of x is 19.

HELPP I WILL GIVE BRAINLEST AND BUNCH OF POINTS
Kryger [21]
Use the formulas for the area of a triangle and the area of a rectangle for both figures. The bases are the tops and bottoms of the figures and the lateral sides are the sides not including the top or bottom. It’s basically just finding the areas of each side and adding them all up to find the surface area. Volume is finding the area of the base, using the triangle area formula, and multiplying that by the height of the figure
