What is the slope of the line that passes through the points (-2, -3), and (5, 4)?

fomenos

Hi!

<h3>To find the slope, use this formula</h3>

$\frac{y2-y1}{x2-x1}$

<h3>Put in the values</h3>

$\frac{4-(-3)}{5-(-2)}=\frac{7}{7}simplify=1$

<h2>The slope is 1 </h2>

Hope this helps! :)

The accompanying data on IQ for first-graders at auniversity lab school was introduced in Example 1.2.82 96 99 102 103 103 106 1

almond37 [142]

Answer:

Mean = 113.72

The estimator of 113.72 is point estimate used for the conceptual population of all first-graders in this school

Step-by-step explanation:

Data provided in the question:

Data:

82 96 99 102 103 103 106 107 108 108 108 108 109 110 110 111 113 113 113 113 115 115 118 118 119 121 122 122 127 132 136 140 146

Number of data = 33

In the hint it is also given that the sum of the data value i.e ∑x = 3753

Now,

Point estimate of mean is given as;

Mean = $\frac{\textup{Sum of all the data values}}{\textup{Total number of data value}}$

⇒ Mean = $\frac{\textup{3753}}{\textup{33}}$

⇒ Mean = 113.72

Hence,

The estimator of 113.72 is point estimate used for the conceptual population of all first-graders in this school

An art exhibit at a local museum features several similarly shaped metal cubes welded together to make a sculpture. The smallest

borishaifa [10]

Answer: Length of other edges will be 7.5 inches, 8 inches, 9 inches, 10.5 inches, 12 inches.

Explanation:

Length of smallest cube = 6 inches

Ratio of similarity to the smallest cube is given as follows:

1) 1.25

So, length of other edge will be

$1.25\times 6=7.5\ inches$

2) 4:3

So, the length of other edge will be

$\frac{4}{3}\times 6=8\ inches$

3) 1.5

So, length of other edge will be

$1.5\times 6=9\ inches$

4) 7:4

So, length of other edge will be

$\frac{7}{4}\times 6=10.5\ inches$

5) 2

So, length of other edge will be

$2\times 6=12\ inches$
