The cake store is having a 25\%25% off sale on all of its cakes. If the cake you want regularly costs \$9$9, how much would you
Ivanshal [37]

Answer:

You would save $2.25.  

Step-by-step explanation:

In order to find discount on an item, you need to multiply the discount by the original amount of the item.  In this case, the cake you want regularly costs $9.  If the sale includes a 25% discount, then you need to first convert your percentage to a decimal by dividing by 100:

\frac{25}{100} =0.25

You can then take this amount multiplied by the original cost of the cake to get your discount:

0.25 x 9 = 2.25, so you would save $2.25 with the discount and pay only $6.75 for the cake you want.

Calculate the mean, the variance, and the standard deviation of the following discrete probability distribution. (Negative value
posledela

Answer:

a) Mean is -23.47

b) Variance is 206.59

c) standard deviation is 14.37

Step-by-step explanation:

Given that;

 x              −41        −27        −8         −3

P(X = x)      0.29      0.35      0.21      0.15

X.P            -11.89     -9.45    -1.68     -0.45

a) mean

Mean = ∑X.P = -11.89 +  -9.45 + -1.68 + -0.45

Mean = -23.47

b)  the variance

E(x²) = ∑x²P(X=x)

= (−41²×0.29) + (−27²×0.35) + (−8²×0.21) + (−3²×0.15)

= 487.49 + 255.15 + 13.44 + 1.35

= 757.43

So

Var(X) = E(x²) - [∑X.P]²

Var(X) = 757.43 - [-23.47]²

= 757.43 - 550.8409

= 206.5891 ≈ 206.59

Therefore Variance is 206.59

c) standard deviation

standard deviation SD(X) = √Var(X)

SD(X) = √206.5891

= 14.3732 ≈ 14.37

Therefore standard deviation is 14.37
