2500/10= 250 pounds.

250 x 1000= 250,000 punds eaten in 1000 days.

The ordered pairs in the table below represent a linear function.
Lilit [14]

Answer:

The slope is 2

Step-by-step explanation:

Given

x   y

2    3

5    9

Required

Determine the slope

First, we have:

(x_1,y_1) = (2,3)

(x_2,y_2) = (5,9)

The slope is then calculated as:

m = \frac{y_2 - y_1}{x_2 - x_1}

This gives:

m = \frac{9-3}{5-2}

m = \frac{6}{3}

m =2

<em>Hence, the slope is 2.</em>

An administrator at a local high school wants to investigate whether there is an association between the grade level of a studen
Nataliya [291]

Answer:

c.

Step-by-step explanation:

The following is how the p-value should be interpreted:

The probability of getting the test statistics value at least as intense as it might have been acquired during the test, assuming the null hypothesis is true, is considered as the p-value.

Null hypothesis

\mathbf{H_o :} A student's grade level has no bearing or association on how they commute to school.

Alternative hypothesis;

\mathbf{H_1: } There is a link between a student's grade level and the way they get to school.

The test statistic's value is 14.63, and the p-value is 0.2636.

As a result, the p-value is interpreted as that of option c in the question.
