Six different​ second-year medical students at Bellevue Hospital measured the blood pressure of the same person. The systolic re

adings​ (in mmHg) are listed below. Find the​ range, variance, and standard deviation for the given sample data. If the​ subject's blood pressure remains constant and the medical students correctly apply the same measurement​ technique, what should be the value of the standard​ deviation? 148 147 138 150 125 144 a. Range equals nothing mmHg b. Sample varianceequals nothing mmHgsquared ​(Round to the nearest tenth as​ needed.) c. Sample standard deviationequals nothing mmHg​ (Round to the nearest tenth as​ needed.) What should be the value of the standard​ deviation? A. ​Ideally, the standard deviation would be zero because all the measurements should be the same. B. ​Ideally, the standard deviation would be one because all the measurements should be the same. C. ​Ideally, the standard deviation would be one because this is the lowest standard deviation that can be achieved. D. There is no way to tell what the standard deviation should be.

Determine the value of x
KATRIN_1 [288]

Answer:

The value of x is 12 feet

Step-by-step explanation:

The shape in question is a composite shape. We can see that x is both the base of the triangle and the breadth of the rectangle.

To get the area of the shape, we will have to add the area of the rectangle to the area of the triangle.

Area of rectangle = length X breadth

Area of triangle = 1/2 base X height.

However, to calculate the area of the triangle, we need to find its height first.

The next step is to get the height of the triangle. Observing the shape properly, we can see that we can get the height by subtracting the length of the rectangle from the overall length of the shape.

Height of triangle = 16 ft - 10 ft = 6 ft

recall area = 156 square feet.

We now have most of our missing dimensions

We can now set up an equation as follows:

(10 \times x) +0.5 \times x \times 6 = 156

10x +3x=156\\13x=156\\x=12 feet

Therefore the value of x is 12 feet

A lookout tower is 16 meters tall. Its shadow is 12 meters long. Close by, there is a wooden column that is 4 meters tall. How l
Lelechka [254]

Answer:

3 metres

Step-by-step explanation:

If we draw this out, we'll see that there are actually two similar right triangles (see attachment), which means that we can set up a proportion.

The height of the lookout tower corresponds to the height of the wooden column, while the shadow of the lookout tower corresponds to the shadow of the wooden column. We can then write:

(height of lookout tower) / (shadow of tower) = (height of column) / (shadow of column)

16 / 12 = 4 / x , where x is the shadow / unknown we want to find

Cross-multiply:

16x = 48

x = 3

The answer is thus 3 metres.
