Witch-in-training Blythe buys a box of chocolate frog cupcakes for her new neighbors, but they look so delicious, she decides to try a copy spell to create an extra batch for herself. But oh,
no, the spell goes wrong, and now the cupcakes won't stop copying themselves. There were 12 cupcakes to start off with, and their numbers increase at a rate of 20% per minute. Which
equation below could be used to determine how many cupcakes there will be after 'm' minutes?

Answer:

[tex] s = 7t [/tex]

Step-by-step explanation:

The table given shows that both variables are directly proportional to each other. That is, as s variable increases, y variable also increases.

Equation to represent this direct proportion would be:

[tex] s = kt [/tex],

where, k = constant of proportionality.

Let's find k from the table given.

Let's use any pair values of of s and t given in the table. Say, s = 21, t = 3

[tex] s = kt [/tex]

[tex] 21 = k3 [/tex]

Divide both sides by 3

[tex] \frac{21}{3} = \frac{k3}{3} [/tex]

[tex] 7 = k [/tex]

[tex] k = 7 [/tex]

Plug in k = 3 into [tex] s = kt [/tex]:

[tex] s = 7t [/tex]

Answer:

5, and 20

Step-by-step explanation:

5+20=25

reciprocal of 5 is 1/5 and reciprocal of 20 is 1/20 so 1/5=4/20 and 4/20 + 1/20 = 5/20. 5/20 = 1/4

Answer:

There is approximately 4% chance that the cable company will keep the shopping channel, even though the true proportion who watch it is only 0.20.

Step-by-step explanation:

The random variable X can be defined as the number of subscribers of a cable television company who watch the shopping channel at least once a week.

X follows a Binomial distribution with parameters n = 100 and p = 0.20.

But the sample selected is too large and the probability of success is close to 0.50.

So a Normal approximation to binomial can be applied to approximate the distribution of X if the following conditions are satisfied:

1. np ≥ 10

2. n(1 - p) ≥ 10

Check the conditions as follows:

 [tex]np=100\times 0.20=20>10\\\\n(1-p)=100\times 0.80=80>10[/tex]

Thus, a Normal approximation to binomial can be applied.

[tex]\hat p\sim N(p,\frac{p(1-p)}{n})[/tex]

Compute the approximate probability that the cable company will keep the shopping channel, even though the true proportion who watch it is only 0.20 as follows:

[tex]P(\hat p>0.27)=P(\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}>\frac{0.27-0.20}{\sqrt{\frac{0.20(1-0.20}{100}}})[/tex]

                   [tex]=P(Z>1.75)\\=1-P(Z<1.75)\\=1-0.95994\\=0.04006\\\approx 0.04[/tex]

Thus, there is approximately 4% chance that the cable company will keep the shopping channel, even though the true proportion who watch it is only 0.20.

Hi There!

Your answer is:

Length = 116

Width = 56

Step-by-step explanation:

L= 4+ 2w

Width=w

perimeter formula

l+l+w+w= perimeter

Subsitute L for 4+2w

(4+2w)+(4+2w) + (w) + (w) = 344

8 +4w+w+w = 344

8+ 6w = 344

-8

6w = 336

/6

w= 56

PLUG BACK IN!

Length = 4+ 2w

Length = 4+ 2(56)

Length = 116

Width = 56

Answer:

1222.2

explanation:

53.95 x 12 = 647.40

17.95 x 12 = 215.40

29.95 x 12 = 359.40

647.40 + 359.40 + 215.40 = 1222.2

The total cost for a team of 12 players as per given cost of different equipment's is equal to $1222.20.

To calculate the total cost for a team of 12 players,

Add up the costs of the required equipment for each player.

The equipment includes a glove, a hat, and a pair of cleats.

Cost of one glove = $53.95

Cost of one hat = $17.95

Cost of one pair of cleats = $29.95

Now, we need to calculate the total cost for each player by adding the costs of all three items:

Total cost per player = Cost of glove + Cost of hat + Cost of cleats

Total cost per player = $53.95 + $17.95 + $29.95

Total cost per player = $101.85

Finally, to find the total cost for a team of 12 players, multiply the total cost per player by the number of players:

Total cost for the team of 12 players = Total cost per player × Number of players

Total cost for the team of 12 players = $101.85 × 12

Total cost for the team of 12 players = $1222.20

Therefore, the total cost for a team of 12 players is $1222.20.

Answer:

The slope is -1/1 or just -1.

(When you need to plot the slope, you use -1/1 to use the strategy Rise/Run or Rise over Run.

If you look at the point (-3,1) From that point, you go down -1 and you run to the side for a positive 1.

Once you do that you'll land at (-2,0) and you can keep on repeating this and you'll see that it lands on the points on the line.

then subtracting this amount from $60  we have

$60 - $30 = $30

it 1 GB costs $10

therefore dividing this amount with $30

we have

$30/$10 = 3

Alejandro can only afford 3GB per month.

Answer:

8 4/7

Step-by-step explanation:

Use a proportion.

Let the unknown number of laps for 30 minutes be x.

7 minutes is to 2 laps as 30 minutes is to x laps

7/2 = 30/x

Cross multiply.

7x = 2 * 30

7x = 60

x = 60/7

x = 8 4/7

Answer: 8 4/7

Isabella walks twice around the gym track in 7 minutes. She can do 60/7 laps of the track in a half hour if she continues moving at this pace.

Running a lap is equivalent to making a full circle of a track during a race or while exercising while walking. the front portion of the human body, when seated, from the waist to the knees. the area of clothing that, while a person is sitting, covers the front of their body from the waist to their knees. a location, setting, or circumstance that promotes rest or nurturing: the lap of luxury.

Laps are being done to get a good workout. For beginners, 20–30 laps in 30 minutes is frequently an effective and reachable target. If you're more advanced, try to do 40 to 50 laps in the same amount of time, and aim for 60 or more.

Let x equal the undetermined number of laps for 30 minutes.

7 minutes equals 2 laps, while 30 minutes equals x laps.

[tex]\frac{7}{2} = \frac{30}{x}[/tex]

Cross multiply.

[tex]7x = 2 \times 30\\7x = 60\\x = \frac{60}{7}\\[/tex]

Therefore, Isabella can do 60/7 laps of the track in a half hour if she continues moving at this pace.

The number of laps covered by Rita, John, and Rodell will be 300, 900, and 925, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The three swimmers who collected the most cash were Rita (A), John (B), and Rodell (C). Together they swam a sum of 2125 laps. John swam threefold the number of laps as Rita, and Rodell swam 25 additional laps than John.

Then the equations are given as,

A + B + C = 2125       ...1

B = 3A                       ...2

C = 25 + B                ...3

From equations 1, 2, and 3, then we have

B/3 + B + 25 + B = 2125

B/3 + B + B = 2100

(7/3)B = 2100

B = 2100 x 3 / 7

B = 900 laps

Then the value of A will be given as,

A = 900 / 3

A = 300

Then the value of C will be given as,

C = 900 + 25

C = 925

The number of laps covered by Rita, John, and Rodell will be 300, 900, and 925, respectively.
