If the standard deviation for a set of data is 9.5. The margin of error is: 19.5.

<h3>Margin of error</h3>

Using this formula

Margin of error=Standard deviation×Mean

Let plug in the formula

Margin of error=205 × 9.5%

Margin of error = 19.475

Margin of error = 19.5 (Approximately)

Therefore If the standard deviation for a set of data is 9.5. The margin of error is: 19.5.

schepotkina [342]

Answer:

His collection increased in a 20%.

Step-by-step explanation:

If 100% represents 10 records, what percentage would be for 12 records?

x = 12 100% / 10 = 120%

So, if we subtract 120% - 100%, it's gonna result in a difference of 20%, which means that 12 represents a 20% more, or his collection increased in a 20%.

An artificial lake is in the shape of a rectangle and has an area of 9/20 square mile. The width of the lake is 1/5 the length o
Zina [86]
X=width of the lake
y=length of the lake.
we set out this system of equiations
x*y=9/20
x=y/5
we solve by sustitution method
(y/5)*y=9/20
y²/5=9/20
y²=(5*9)/ 20
y²=2.25
y=√2.25=1.5

x=y/5
x=1.5/5=0.3

Solution:
width of the lake=0.3 miles
lenght of the lake=1.5 miles

90 POINTS!!!!! Given: KLIJ inscr. in k(O),m∠K = 64°, measure of arc LI = 69°, measure of arc IJ = 59°, measure of arc KJ =97°
Kay [80]

In any cyclic quadrilateral, angles opposite one another are supplementary, meaning

m\angle K+m\angle I=m\angle L+m\angle J=180^\circ

and given that \boxed{m\angle K=64^\circ}, we have \boxed{m\angle I=116^\circ}.

By the inscribed angle theorem,

m\angle JLK=\dfrac12m\widehat{KJ}

m\angle ILJ=\dfrac12m\widehat{IJ}

and since

m\angle L=m\angle JLK+m\angle ILJ

we have

m\angle L=\dfrac{97^\circ+59^\circ}2\implies\boxed{m\angle L=78^\circ}

and it follows that

m\angle J=180^\circ-m\angle L\implies\boxed{m\angle J=102^\circ}

NEED HELP FAST CLICK TO SEE PLS
ss7ja [257]

Answer:

Last Option

Step-by-step explanation:

Last one because the dot on top of the 4 is filled in and that means it can also equal 4. The rest of the line is going to the right of the 4 so x will be more than 4. The little line below the more than sign means it can also equal 4. Hope this helped :)
