Answer: 6

Step-by-step explanation:

There are 6 different combinations of choices for the date:

  1. Thai food, movie
  2. Thai food, ice skating
  3. Thai food, art museum
  4. Italian food, movie
  5. Italian food, ice skating
  6. Italian food, art museum

An easier way to solve for this is multiply by how many choices are in each category.

In food there is 2 choices, in activities there is 3 choices

Therefore:  2 x 3 = 6

A rectangle's length is twice its width. if the perimeter is 120 cm, find the width of the rectangle.
dangina [55]
Let's use the formula to find the perimeter of a rectangle.
2l+2w=120
We know that the length is twice its width; the equation would be:L=2w
We can plug that in to the formula.
2(2w)+2w=120
4w+2w=120
6w=120
120÷6=20=w
Since the length is twice its width, 20×2=40. The length is 40 cm.
The width is 20 cm.

Which of the following is perfect square trinomial. Ive asked 4 times. Please Help. Will give brainlilest
Nutka1998 [239]

Answer:

D

Step-by-step explanation:

a perfect square trinomial is

a^2x^2\pm2(ab)xy+b^2y^2

factorized is

(ax\pm by)^2

so as you can see option A and B can't be, because they have -49y^2 and it has to be plus

so the other options are C and D

in the trinomial a=4 and b=\pm 7

the roots of a^2 and b^2

\pm2abxy=\pm2(4)(7)xy\\\\=\pm56xy

so it's option d with b=-7

16x^2-56xy+49y^2

distribution has a mean if 18 standard deviation of 4 a value of 24 is how many standard deviations away from the mean
liraira [26]

A  value of 24 is 2.5 standard deviations away from the mean

<h3>'How to determine the number of standard deviations away from the mean?</h3>

The given parameters about the distribution are:

Mean = 18

Standard deviation = 4

Value = 24

Let the number of standard deviations away from the mean be x.

The value of x is calculated using

Mean + Standard deviation * x = Value

Substitute the known values in the above equation

18 + 4 * x = 24

Subtract 18 from both sides of the equation

4 * x = 6

Divide both sides of the equation by 4

x = 1.5

Hence, a value of 24 is 2.5 standard deviations away from the mean

So, the complete parameters about the distribution are:

Mean = 18

Standard deviation = 4

Value = 24

24 is 2.5 standard deviations away from the mean
