Answer:

The area of 1 slice of pizza is 56.5 cm² .

Step-by-step explanation:

In order to find the area of one slice, you have to find the area of the whole pizza using the area of circle, A = π×r² where r represents radius :

Let r be 12 cm,

A = π×12²

= 144π cm²

It is given that this pizza can be cut into 8 slices. So you have to divide it by 8 :

144π ÷ 8

= 56.5 cm² (3s.f)

If the Greatest Common Factor of L and M is 6, write the expression for the Least Common Multiple of these numbers.
zhuklara [117]

Answer:  

\frac{(L x M)}{6}

Step-by-step explanation:  

The greatest common factor is the greatest number that will divide two values. We have two values L and M. Each has numbers which multiply together to give the number. The highest value or most in common they share is 6. This is the GCF.

The least common multiple is the smallest positive number which is a multiple of the two. This means both L and M divide into it evenly.

We know L x M is a multiple because L and M will be factors of it. But we don't know its the least.

As an example if L= 42 and M = 60, they have GCF 6. We can multiply them to find a multiple 42 x 60 = 2520 but we don't know this is the smallest or least multiple we can find. If we divide by the GCF, 2520/6=420. Interestingly, 42 x 10 =420 and 60 x 7 =420. This means 420 is the least common multiple.  

We can multiply (L x M) and then divide by the GCF of L & M to find the least common multiple.

\frac{(L x M)}{6}

Labor economists have extensively researched the determinants of earnings. Invest-ment in human capital, measured in years of ed
never [62]

Answer:

Kindly check explanation for other solutions

Years, Inning and saves are statistically significant ; ERA is not.

Step-by-step explanation:

Earning for staying one additional year :

Multiply slope value of years * 1 = 0.052 * 1 * 100 % = 5.2% (earning increases by 5.2%)

Relives with 10 more saves :

10 * 0.0032 * 100% = 3.2% (earning increases by 3.2%)

Having 100 more innings :

100 * 0.00089 * 100% = 8.9%

If ERA is reduced by 1.5 ; earning will increase by (0.0085*100)% * 1.5 = 1.275%

B.) At 5% level of confidence :

α = 1.64

Years = 0.052/0.026=2

Inning = 0.00089/0.00020 = 4.45

Saves = 0.0032/0.0018 = 1.78

ERA = 0.0085/0.0168 = 0.51

Years, Inning and saves are statistically significant as they are greater than α ; As for ERA, it is not statistically significant (0.51 < 1.64)
