6 0

Answer:

Step-by-step explanation:

if the question is

-7p * -4r * 39

then it's

-1*-1*7*4*39*p*r

now you just need a calculator to find the numbers that are multiplied together

-1 * -1 = 1

7*4=28

28*39*p*r

1092*p*r

1092pr

The area of a circular plate is 625pi sqaure in. If the radius of the plate is tripled what is the new area
goldenfox [79]

Answer:

5625in²

Step-by-step explanation:

Area of the plate = πr²

625π = πr²

625 = r²

r = √625

r = 25in

If the radius of the plate is tripled, then the new radius will be 3(25) = 75in

New Area = π(75)²

New Area = 5625π in²

If the radius is tripled, the new area of the plate is 5625in²

Suppose you have a right triangle with congruent legs and a hypotenuse that measure (12sqrt(5))/5 What is the length of the smal
anastassius [24]

The length of the smaller leg is 3.79

<h3>How to determine the length of the smaller leg?</h3>

Represent the smaller leg with x.

So, we have:

x^2 + x^2 = ((12\sqrt5)/5)^2 -- Pythagoras theorem

This gives

2x^2 = 144/5

Divide by 2

x^2 = 72/5

This gives

x^2 = 14.4

Take the square root

x = 3.79

Hence, the length of the smaller leg is 3.79

Sales prices of baseball cards from the 1960s are known topossess a skewed-right distribution with a mean sale price of $5.25and
Serga [27]

Answer:

c. Skewed-right with a mean of $5.25 and a standard error of$0.28

Step-by-step explanation:

As we have given that Sales prices of baseball cards have a right-skewed distribution with a mean $5.25 and a standard deviation is $2.80.

Now, We know that if standard deviation = σ

then, standard error = \frac{\sigma}{\sqrt{n}}

As, we have standard deviation = $2.80

then standard error will be \frac{2.80}{\sqrt{100}}

⇒ Standard error = $0.28

Hence, Option (c) is the correct option.
