The percent increase is: 35.5%

Step-by-step explanation:

The percentage increase is given by:

Percent\ increase=\frac{Increase}{Initial\ value}*100

Where

Increase=New\ quantity-old\ quantity\\

Given

Initial weight of puppy = 6.7 pounds

New weight of puppy = 9.38 pounds

Increase = New weight of Puppy - Initial weight of puppy

=9.38-6.7 =2.68

Now,

Percent\ increase\ in\ weight=\frac{Increase}{Initial\ weight}*100\\=\frac{2.38}{6.7}*100\\=0.355*100\\=35.5\%

The percent increase is: 35.5%

kirill [66]

Answer:

1, \frac{m}{n}, \frac{1-m}{n}.

Step-by-step explanation:

probability = \frac{Number of Possible Outcomes}{Total Outcomes}

Total number of persons in the party = n

a) Pr ( every person gets their phone back) = Pr (each person picks his phone ) multiplied by number of person

   = \frac{1}{n} × n = 1.

     No of first m persons to pick = m

     No of last m persons to pick = 1 - m

b) Pr (first m persons to pick each gets their phones back) = \frac{m}{n}

c) Pr( first m persons get a phone belonging to last m persons) = \frac{1-m}{n}

Why do plasma particles have charges?​
r-ruslan [8.4K]

Answer:

"Because the particles (electrons and ions) in a plasma have an electrical charge, the motions and behaviors of plasmas are affected by electrical and magnetic fields. ... Ions have a positive electrical charge because they have more positively charged protons than negatively charged electrons."

Andreyy89

Answer:

180 miles

Step-by-step explanation:

Going North

<em><u>Formula</u></em>

d = r * t

<em><u>Givens</u></em>

r = 60 mph

t = 5.2 hours

d = ?

<em><u>Solution</u></em>

d = 5.2 * 60 = 312 miles north

Going South

<em><u>Givens</u></em>

r = 55 mph

t = 2.4 hours

<em><u>Solution</u></em>

d = r * t

d = 55 * 2.4

d = 132

Distance from home

Formula: Distance from home = Distance North - Distance South

Distance North = 312  -   132 = 180 miles

The average of five distinct scores has the same value as the median of the five scores. The sum of the five scores is 420. What
givi [52]

Answer:

The sum of five scores that is not the median is, 336

Step-by-step explanation:

Average defined as the  the sum of the observation to the total number of the observation.

Given: The sum of the five scores is 420

Then, by definition of average;

Average of five distinct score = \frac{420}{5} = 84

It is also, given that the average of five distinct scores has the same value as the median of the five scores.

⇒Median of five scores = 84

Since, scores are distinct, therefore

Sum of all scores that is not the median = Sum of five scores - median = 420-84 = 336

therefore, the sum of five scores that is not the median is, 336
