You're given the y-intercept, which is (0,5), so to complete the slope intercept form, you now need to find the slope. slope is the change in y over the change in x, so take points (4,-1) and (2,2) for instance and apply the formula; -1-2= -3 and 4-2=2, so the change in y is -3 and the change in x is 2. to find the slope, you divide change in y by change in x, which is -3/2. from here, you can gather that the slope intercept form is y= -3/2x + 5

Kirti knows the following information from a study on cold medicine that included 60 participants: 30 participants in total rece

GalinKa [24]

The frequency table is attached.

Since there were 30 people out of the 60 that received cold medicine, that means that 60-30=30 people did not.

Since 26 people had a cold longer than 7 days, this means 60-26=34 had a cold that was less than or equal to 7 days.

14 people had a cold longer than 7 days and received medicine; this means that 26-14=12 people had a cold longer than 7 days and did not receive medicine.

30-14=16 people received medicine and had a cold less than or equal to 7 days.

30-12=18 people did not receive medicine and had a cold less than or equal to 7 days.

360 — A

___________________________________________________

Step-by-step explanation:

This is a square based pyramid. Which means that all of the triangles have the same area. All you need to do is find the area of one triangle, multiply it by 4, and add that to the area of the square base.

___________________________________________________

Step 1) FIND THE AREA OF ONE TRIANGLE

Imagine the triangle as a flat 2D shape. The height of this shape would be 13km, that mush is given to us. The length is also given, 10km.

How to find the area of a triangle:

Multiply the height times the width and divide the result by 2.

1. 13 x 10 = 130

2. 130/2 = 65

The area of this triangle is 65km squared.

___________________________________________________

Step 2) MULTIPLY BY 4

65 x 4 = 260

___________________________________________________

Step 3) FIND THE AREA OF THE SQUARE

When you find the area of a square, all you need is the length of one edge. That is 10km in this case.

Multiply this length by itself,

10 x 10 = 100

___________________________________________________

GETTING THE FINAL ANSWER

Add all your results :

260 + 100 = 360
