20% increase

the percent increase = $\frac{increase}{original}$ × 100%

increase = $12 - $10 = 2$

increase = $\frac{2}{10}$ × 100% = 20%

Find the percent cost of the total spent on each:

natta225 [31]

The right answer is 18%,61%,21%

Step-by-step explanation:

Given,

Amount spent on equipment = $46

Amount spent on fees = $152

Transportation = $52

Total spent = Equipment + Fees + Transport

Total spent = 46+152+52 = $250

Percent spent on equipment = $\frac{Amount\ spent\ on\ equipment}{Total\ spent}*100$

Percent spent on equipment = $\frac{46}{250}*100 = 18.4\%$

Rounding off to nearest percent

Percent spent on equipment = 18%

Percent spent on fees = $\frac{Amount\ of\ fees}{Total\ spent}*100$

Percent spent on fees = $\frac{152}{250}*100 = 60.8\%$

Rounding off to nearest whole percent

Percent spent on fees = 61%

Percent spent on transportation = $\frac{Amount\ spent\ on\ transportation}{Total\ spent}*100$

Percent spent on transportation = $\frac{52}{250}*100 = 20.8\%$

Rounding off to nearest whole percent

Percent spent on transportation = 21%

The right answer is 18%,61%,21%

You collect baseball cards and buy sealed packs from the grocery store and clearly have no idea which cards are inside (nor if t

ololo11 [35]

Answer:

(a) 0.9607

(d) 0.8184

(e) 0.074

(f) 0.0853/e^0.8;

750 cards

Step-by-step explanation:

Let the probability of success of a valuable card be p

p= 1/250 = 0.004,

q = 1-p = (249/250)

(a) There are 10 cards in one pack

The probability that there are no valuable card is given by:

Pr(X= 0) = 10C0 × (1/250)^0 ×(249/250)^10

10C0 = 10 combination 0= 10!/10!0!

Pr (X= 0) = (249/250)^10

Pr (X=0) = 0.9607

E(X) = np , n= 10, p= 1/250

E(X) = 10 × 1/250 = 1/25 = 0.04

(d) 5 packages means 5 × 10= 50 cards

Pr(X=0) = 50C0 × (1/250)^0 ×(249/250)^50

50C0 = 50!/50! ×0!=1

Pr (X=0) = (249/250)^50

Pr (X= 0) =(0.996)^50

Pr (X=0) = 0.8184

(e) For this case we use the Binomial Distribution

2 packages 2 × 10 = 20 cards

n = 20 , x = 1

We use:

P(X=1) = 20C1 × (1/250)^ 1 × (249/250)^19

Pr (X=1) = 20C1 × (1/250)^1 × (249/250)^19

Pr (X=1) = 20 × (1/250)¹ × (249/250)^19

Pr (X= 1 )= 0.074

(f) 20 packages = 200 cards

For this we apply Poisson distribution

P(X=3) = (e ^-h × h ^x) / x!

Where h = np = 200/250 = 0.8

P(X=3) = e^-0.8 × (0.8)^3 / 3!

P(X=3) = 0.991 × 0.512/6

P(X=3) = 0.0846

3 = n p

n = 3/p = 3 /0.04

n = 750 cards

How does the setting of a story influence a characters feelings and actions?

Ratling [72]

Answer + Step-by-step explanation:

Settings can affect the character in a number of ways.

For example, it can cause conflict and influence the character's

actions. In the setting of a war, it will obviously cause conflict

for a character or change the character's attitude towards another

character whom they probably knew well. The setting can affect the mood

and tone of the scene, resulting in many actions the reader did not think was

going to happen before.
