Answer:

Two standard deviations

Step-by-step explanation:

The Z score is obtained using the mean and standard deviation, according to the empirical. Rule, which gives percentage of values that lie within an interval estimate in a normal distribution ;

one standard deviation lie within 68% of the mean

Two standard deviations lie within 95%

Three standard deviations lie within 99.7%

Hence, for the question given, 95% fall within 2 standard deviations of the mean

Slope intercepts <br> No links, Will mark BRAINLIEST
Sergeeva-Olga [200]

Answer:

<em><u>Lines are perpendicular to each other .</u></em>

Step-by-step explanation:

Standard equation  of line is : y = mx + c, Where m represents the slope

Given Equations :

y = -5x + 1\\\\Slope , m_1 = -5

y = \frac{1}{5}x +1\\\\Slope, m_2 = \frac{1}{5}

Two lines are parallel if the slope of the lines are same.

Two line are perpendicular if the product of the slope = - 1

Clearly slopes are not equal , therefore the lines are not parallel.

           product of the slope is - 1, therefore the lines are perpendicular.  

                                m_1 \times m_2 = -5 \times \frac{1}{5} = - 1

Multiply x^2-8x+15/3x * 8x/x-3
sergejj [24]
You must follow the steps below:

 1. First, you should apply the dstributive property:

 =(x²-<span>8x+15/3x)(8x/x-3)
 =(8</span>x³-64x²+120x)/3x(x-3)

 2. As you can see, the common factor in the numerator is: "8x". So, you have:

 =8x(x²-8x+15)/3x(x-3)

 3. Then, when you simplify, you obtain:

 =8(x²-8x+15)/3(x-3)

 Therefore, the solution is: 8(x²-8x+15)/3(x-3)
