Answer:

False (I assume it's a true/false question)

Step-by-step explanation:

Standard deviation measures how spread out the data is.  If you add 8 to all the data values, the distribution of data moves to the right (on a graph) 8 units. The shifted data are no more and no less spread out than before.  The standard deviation does not change.

Draw a circle with center A and a radius of your choice. Create three well-spaced points, B, C, and D, on the circle in clockwis
Dmitry [639]

Answer:

Please find attached the required circle

It is observed that the angle subtended by the arc CB which are m∠CAB and m∠CDB is such that the angle arc CB subtends at the center,  m∠CAB is two times the angle that the arc CB subtends at the circumference

The measured angle subtended by the arc CB at the center m∠CAB = 64° and the measured angle subtended by the arc CB at the circumference m∠CDB = 32°

A plant is already 14 centimeters tall, and it will grow one centimeter every month.
Semenov [28]

Answer:

H=M+14

Step-by-step explanation:

When writing an equation you should always look at the problem and try to figure out what it is asking you to solve for. In this case you would be solving for the plants height (H). That will be one side of our equation.

<u>H=???</u>

Now we must think about how we would solve for the height. The plant grows 1 centimeter each month so we will put M on the other side. But since it is we will add 14 to that.

<u>H=M+14</u>

What is the probability that a card picked at random from a 52-card deck of playing cards is a club or a jack?
Anestetic [448]
<span>The probability is given as No of favourable outcomes over total number of events. Now, the no of clubs in a deck of cards is 13 and similarly, the number of jacks in a deck of cards is 13. Then, the probability that a card picked at random from a 52-card deck of playing cards is a club or a jack = 13+13/52 = 26/52 = 1/2 = 50%</span>

The width of a rectangle is 13 units less than the length. If the area is 90 square units, then find the dimensions of the recta
Artemon [7]

If the area is 90 square units. Then the dimension of the rectangle will be 5 units and 18 units.

<h3>What is the area of the rectangle?</h3>

Let L be the length and W be the width of the rectangle.

Then the area of the rectangle will be

Area of the rectangle = L×W square units

The width of a rectangle is 13 units less than the length.

If the area is 90 square units.

W = L – 13

Then we have

                           90 = L(L – 13)

         L² – 13L – 90 = 0

L² – 18L + 5L – 90 = 0

L(L – 18) + 5(L – 18) = 0

         (L – 18)(L + 5) = 0

                             L = -5, 18

Then the width will be

W = 18 – 13

W = 5 units

Then the dimension of the rectangle will be 5 units and 18 units.

More about the area of the rectangle link is given below.

Two possible floor plans for a new bathroom are shown.
Neko [114]

Answer:

Hope it works for u

Step-by-step explanation:

As we have given two shapes bathroom

square and rectangle

Parameter of square= sum of all the sides   ( : In square all sides are equal

Parameter of square= 4*L  = 4*(x+3)       (:L=x+3

similarly,

In rectangle opposites sides  are equal hence

Perimeter of rectangle= 2*length+2*width  ( : length=x+4,width can't be seen clearly so I assume and take it width=x+1  hope this is equal to the width of ur question otherwise do the calculation by ur self).

Perimeter of rectangle= 2*(x+4)+2(x+1)

so now we have to find the value of "x" for which both perimeter are equal, so

perimeter of square= perimeter of rectangle

4*(x+3)=2*(x+4)+2(x+1)  we can also write as

<h2>2(x+3)+2(x+3)=2(x+4)+2(x+1)</h2><h3>This is the linear equation required</h3><h3>now to find value of "x"</h3><h3>simplify both sides, we get</h3><h3>4x+12=4x+10</h3><h2>0≠2 so that not true and also there is no value of "x"</h2>

for which both parameters become equal

<h2>so from my side "b" option is correct</h2>

Please brain-list it if u find it help-full it requires effort!
