Dana needs 6 meters of ribbon to make bows. She has 160 centimeters of ribbon. Does Dana have enough ribbon to make bows? Explai

ozzi

No; to make a bow, you need 6 meters and 6 meters = 600 centimeters. If Dana only has 160 centimeters of ribbon, bows cannot be made because 600 cm is more than 160 cm.

What is the value of x using the Pythagorean theorem?

Vesnalui [34]

A^2+b^2= c^2

Plug in the points. the longest side is always c.

95.2^2+ b^2= 168^2.

Square the numbers.

9063.04+ b^2= 28224

Subtract 9063.04 on both sides.

b^2= 19160.96

Find the square root.

b= 138.423119456

Or, b= 138.4 (rounded down)

ExtremeBDS [4]

Answer:

Step-by-step explanation:

From the given sample of 10 entries we find

Mean =119.2

Median =120

Point estimate of μ.= $19.2$

b) Suppose there are 25,000 houses in this area that use natural gas for heating. Let τ denote the total amount of gas used by all of these houses during January.

τ = $25000(119.2)\\= 2980000$

c) Proportion would be sample proportion = $\frac{8}{10} =0.8$

d) Population median usage = sample median usage = 120
