when your finding the area of a rectangle do you multiply the numbers around the perimeter or add them.

Flura [38]3 years ago

When you are finding the area, you multiply the length x the width. So for example, we have a rectangle that the length is 6 feet and the width is 4 feet. So, first of all we multiply 6x4= 24. Since its area don't forget it is Square Feet (or any other type of measurement).

Hope it helps!

A line passes through the point (–7, 5) and has a slope of One-half. Which is another point that the line passes through?
irina1246 [14]

Answer:

(13, 9)

Step-by-step explanation:

Make an equation for the line.

y = 0.5x + b

5 = -3.5 + b

b = 8.5

y = 0.5x + 8.5

Plug them into the equation.

(-13, 9) 9 ≠ -6.5 + 8.5

(-9, 13) 13 ≠ -4.5 + 8.5

(9, 13) 13 = 6.5 + 8.5

(13, 9) 13 ≠ 4.5 + 8.5

Suppose you have an experiment where you flip a coin three times. You then count the number of heads. a.)State the random variab
WITCHER [35]

Answer:

a) X=number of heads observed when flipped the coin 3 times

b) the probability distribution is

P(X=x) = 3/4 * (1/[(3-x)!*x!)])

or

P(X)=1/8 for x=0 and x=3 and P(X)=3/8 for x=1 and x=2

Step-by-step explanation:

the random variable will be X=number of heads observed when flipped the coin 3 times . Since the result from each flip is independent of the others , then X has a binomial probability distribution , such that

P(X=x)= n!/[(n-x)!*x!)*p^x * (1-p)^(n-x)

where

n= number of times the coin is flipped = 3

p= probability of getting heads in a flip of the coin = 1/2 (assuming that the coin is fair)

therefore

P(X=x)= 3!/[(3-x)!*x!)*(1/2)^(3-x) * (1/2)^x = 3!/[(3-x)!*x!) * (1/2)³ = 3/4 * (1/[(3-x)!*x!)])

P(X=x)= 3/4 * (1/[(3-x)!*x!)])   , for x=[0,1,2,3]

for x=0 and x=3 → P(X)=3/4 * (1/[3!*0!)]) = 1/8

for x=1 and x=2 → P(X)=3/4 * (1/[2!*1!)]) = 3/8

we can verify that is correct since the sum of all the probabilities from x=0 to x=3 is  1/8 +  3/8+ 3/8+ 1/8 = 1

Alisiya [41]

Answer:

<h3>$1850</h3>

Step-by-step explanation:

<h3>If the Original price was $ X , Then </h3>

x - 0.20x \:  = 1480

0.8x = 1480

x = 1480 \div 0.8

<h3>So , X = 1850 dollars .</h3>

Translate the description as an algebraic expression:
charle [14.2K]

Answer:

13/20p

Step-by-step explanation:

Here, we want to write an expression from the given statement

We start from the product of 20 and p

Mathematically. that is 20 * p = 20p

Now to find the ratio, we simply place 12 over the product

We have this as;

13/20p
