Answer:

Rotational symmetry of 180 degrees around the origin - yes

Rotational symmetry of 270 degrees around the origin - no

Step-by-step explanation:

thanks to math bits notebook we can see a visual representation

As you can see the parallelogram has rotational symmetry of 180

What is the area, in square units, of the parallelogram shown below? A parallelogram ABCD is shown with height 7 units and base

enot [183]

Answer:

35 square units

Explanation:

Area of parallelogram is calculated as follows:

Area = base * height square units

In the given question, we have:

base = 5 units

height = 7 units

Substitute with the givens in the above equation to get the area:

Area of parallelogram = 5 * 7 = 35 square units

Hope this helps :)

Which is the most efficient way to solve this equation?

Alona [7]

Answer:

subtracting 7 from 12

Step-by-step explanation:

That would be most efficient. Subtracting seven from twelve will quickly give you your value of x without moving the x itself. And there's no negatives

A packet of garden seeds contains 250 seeds. The information printed on the packet indicates that the germination rate for this

Westkost [7]

Answer:

Expectation=240

standard deviation=3.098

Step-by-step explanation:

This is a binomial probability function with n=250 and probability of success is 96%

-The expected value is calculated as:

$E(X)=np\\\\=250\times 0.96\\\\=240$

Hence, the expected germination is 240 seeds

b. From a above, we have the value of p=0.96 and n=250.

The standard deviation of germination is therefore calculated using the formula:

$\sigma=\sqrt{np(1-p)}, \ \ \ \\\\=\sqrt{250\times 0.96(1-0.96)}\\\\\\=3.098$

Hence, the standard deviation of germination is 3.098

$\textsf{Hey there!}$

$\mathsf{\star \ The\ sum\ of\ a\ number\ \&\ forty-six}$

$\frak{Let's\ lable\ the\ keypoints\ so\ it\ can\ be\ easier\ to\ solve}$

$\bullet \ \textsf{The word \bf{\underline{SUM}}}\textsf{\ means\ add/addition}}$

$\bullet\textsf{ \underline{"A number"} is an unknown number so we can lable it as \bf{x}}$

$\bullet\textsf{ \underline{forty-six} is 46}$

$\textsf{The sum (+) does in the middle while \underline{x} \& \underline{46} will either be on left/right}$

$- \ \textsf{We can say that x is on your left}$

$-\ \textsf{ + can be in your middle}$

$- \ \textsf{\& lastly 46 can be on your right}$

$\boxed{\textsf{Thus, your answer SHOULD LOOK like: \boxed{\huge\text{\bf{x + 46}}}}}\checkmark$
