Answer:

Volume of sphere = 130.9cm³

Step-by-step explanation:

Formula :

\frac{4}{3} \times  \pi \:  \times r^{3}

We need the radius. 6.3 ÷2=3.15

\frac{4}{3}  \times \pi \times 3.15 ^{3}

=130.924303cm³

rounded to the nearest tenth

=130.9cm³

Answer:

The correct answer is C) Reflection across the Y-axis.

Step-by-step explanation:

This is because only the x-coordinates changed. If these coordinates were reflected across both the x and y axis' the sign of both the x and y coordinates would have changed. When  you reflect a point across the x axis, the y-coordinates change their sign. When you <u><em>reflect </em></u><u>a point across the y axis</u>, the <u>x-coordinates change</u> their sign.

Hope this helps,

PLZ HELP ASAP The numbers of motor vehicle fatalities in the United States for the years 2010 and 2011 are listed in the table b
Nonamiya [84]
To find which measure of variability is greater and which average number of monthly fatalities is higher, you will need to calculate the mean and the mean absolute deviation for both years

The mean will tell us which is generally higher, and the mean absolute deviation will tell us which has a greater variability.

The correct answer is D.

Please see the attached picture for the work.

Frank cut a 52 inch string into 3 pieces. The first piece is 20 inches long. The second piece is at least 12 inches long, but no
Eddi Din [679]
We need to figure out how much string would be left, after taking away the first two pieces.
We know that the first piece is 20 inches long, so we can say that there is 52-20 inches left, or 32 inches.

The second piece is between 12 and 18 inches, meaning that there would be between 32-12 and 32-18 inches left for the third piece, or 20 and 14 inches. This means that the third piece would be at least 14 inches long, but no more than 20, since we don’t have more string than that (20+12+20=52, and 20+14+18=52)

So we can say that x is greater or equal to 14, but less than or equal to 20, or:

14<=x<=20 (“<=“ is written like a normal “<“ sign with a line _ right under it)

Answer:

x = 36

y = 37.95

Step-by-step explanation:

By geometric mean property:

{12}^{2}  = 4 \times x \\  \\ 144 = 4 \times x \\  \\ x =  \frac{144}{4}  \\  \\ x = 36 \\  \\

By Pythagoras Theorem:

{y}^{2}  =  {12}^{2}  +  {x}^{2} \\  \\  {y}^{2}  =  {12}^{2}  +  {36}^{2}  \\  \\  {y}^{2}  = 144 + 1296 \\  \\  {y}^{2}  = 1440 \\  \\ y =  \sqrt{1440}  \\  \\  y = 37.95
