The position of the cell phone tower is an illustration of the triangle midpoint

The cell phone tower should be located at  (9, \frac 83)

<h3>How to determine the coordinates of the cell phone tower </h3>

The coordinates are given as:

A(1, 1), B(13, 6), and C(13, 1)

The midpoint is then calculated as:

(x,y) = \frac 13 * (x_1 + x_2 + x_2, y_1 + y_2 + y_3)

So, we have:

(x,y) = \frac 13 * (1 + 13+ 13, 1 + 6 +1)

Evaluate the sum

(x,y) = \frac 13 * (27, 8)

Evaluate the product

(x,y) = (9, \frac 83)

Hence, the cell phone tower should be located at  (9, \frac 83)

Solve for x: 2x - 2 &gt; 4x + 6
laiz [17]

Isolate the x. Subtract 4x from both sides, and add 2 to both sides

2x (-4x) - 2 (+2) > 4x (-4x) + 6 (+2)

2x - 4x > 6 + 2

Simplify. Combine like terms

-2x > 8

Isolate the x. Divide -2 from both sides. Note that you are <em>dividing a negative number</em>. When doing so, flip the sign.

-2x/-2 > 8/-2

x > 8/-2

x < -4

x < -4, or (1) is your answer

hope this helps

Answer:

its \: dimensions \: are \to \\\boxed{w = 17.6cm}  \: \boxed{l = 78.4cm}

Step-by-step explanation:

if \to l = 4w + 8 \\ but  \\ \: perimeter(p )= l + w = 96 \\ 4w + 8 + w = 96 \\ 5w + 8 = 96 \\ 5w = 96 - 8 \\ 5w = 88 \\ w =  \frac{88}{8}  \\  \boxed{w = 17.6cm} \boxed{l = 78.4cm}

A new car battery is sold with a two-year warranty whereby the owner gets the battery replaced free of cost if it breaks down du
Mariana [72]

Answer:

4.01% probability that the battery will break down during the warranty period

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 45, \sigma = 12

a. What is the probability that the battery will break down during the warranty period

Warranty of 2 years = 24 months. So this is the pvalue of Z when X = 24.

Z = \frac{X - \mu}{\sigma}

Z = \frac{24 - 45}{12}

Z = -1.75

Z = -1.75 has a pvalue of 0.0401

4.01% probability that the battery will break down during the warranty period

The slope of the line is 4, and it contains the point: (1,7).
allsm [11]

Answer:

\displaystyle 4x - y = -3, -4x + y = 3, OR\:y = 4x + 3

Step-by-step explanation:

7 = 4 + b

\displaystyle 3 = b \\ \\ y = 4x + 3

If you want it in <em>Standard</em><em> </em><em>Form</em>:

y = 4x + 3

- 4x - 4x

_________

\displaystyle -4x + y = 3\:OR\:4x - y = -3
