The probability for the z-score is greater than or equal to 1.4 is 0.08076 or 8.076 %.

<h3>What is a z-score?</h3>

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The probability for the z-score is greater than or equal to 1.4 is given as

P(z ≥ 1.4) = 1 - P( z < 1.4}

P(z ≥ 1.4) = 1 - 0.91924

P(z ≥ 1.4) = 0.08076

P(z ≥ 1.4) = 8.076 %

Consider the graph of the quadratic function. Which interval on the x-axis has a negative rate of change?

Gre4nikov [31]

The average rate of change is defined as:

$AVR = \frac{f(x2)-f(x1)}{x2-x1}$

For AVR to be negative, it must comply with:

$x2 - x1> 0$

$f (x2)$

Therefore, we observe that the interval that fulfills these conditions is the whole interval to the right of the parabola.

Among the options given, this interval is:

1 to 2.5

Answer:

An interval on the x-axis that has a negative rate of change is:

D. 1 to 2.5

11 x minus 3 y = negative 17. Negative 4 x + 3 y = negative 18. Negative 7 x = negative 35 Negative 7 x = 35 7 x = negative 35 7

posledela

Answer:

7 x = -35

Step-by-step explanation:

Which equation results from adding the equations in this system? 11 x minus 3 y = -17. Negative 4 x + 3 y = - 18.

- 7 x = negative 35

- 7 x = 35

7 x = negative 35

7 x = 35

In this problem we need to add the equations below i.e.

11x-3y = -17 and -4x+3y=-18

Adding both equations,

11x-3y+(-4x)+3y = -17+(-18)

7x= -35

7 x = negative 35

Hence, the correct option is (c).
