Law Incorporation [45]

Answer:

SEE BELOW

Step-by-step explanation:

C = 14.85

S = 16.90

c = 5.99

d = 6.99

3) 0.2(3C+2d)

round C to 15 and d to 7 cause that's about right

No cause that's about 12 and 5 is way too low.

So actually work it out now

0.2(3(14.85)+2(6.99))

0.2(44.55+13.98)

0.2(58.53)

11.706 but in terms of money it would be 11.71

4) 5S+5C+5c+5d

C is about 15, S is about 17, c is about 6, d is about 7

that is about 225

That seems reasonable.

(The real total though is 2223.65)

5) t=1.39

14.85+1.39x=20

Lets round those numbers again to make it easy to work with

15+1.5x=20

1.5x=5

x=3.33333

No, you cannot add 4 toppings and still pay $20

He over estimated

1.39x=5.15

x=3.70503597

you can get 3.

Here is the histogram of a data distribution. 6 5 4 3- 2 1 2 3 6 8 4 5 7 9 10 What is the shape of this distribution?
MakcuM [25]

A histogram can be named based on the number of modes it has.

The shape of the given histogram is (c) bimodal

From the attached figure, we can see that the histogram has 2 modal values at x-values of 2 and 7.

This implies that the histogram is bimodal (i.e. two modes)

Naming the histogram using the number of modes, we can conclude that the shape of the given histogram is (c) bimodal
