3/5 in 30 mins, 5*30=150, then she would write 3/150 or 1/50 each minute

Answer: Ok, so we know that zoe wrote 3/5 of her essay in 30 minutes.

Now, assuming she wrote the paper at a constant rate, then if we divide those 3/5 in 3, we get 1/5 + 1/5 + 1/5, t we also divide the time by the same number, then:

1/5 + 1/5 + 1/5 = 10m +10m +10m

so she wrote a 1/5 of her essay in 10 minutes.

if we divide by 10 this time, we get 1/50 = 1 minute.

then she wrote 1/50 of her essay per minute.

Ede4ka [16]
Where is table y? 

Considering that Livia eats chicken drumsticks with 11 grams of protein and cheese sticks with 7g of protein, we can determine that for each chicken drumstick, she will receive 11 grams of protein.

For each cheese stick, she will eat 7g of protein.

If she eats 10 cheese sticks, she will eat 70 gram of protein. 

This funciton is dependent on the amount of cheesesticks she's eaten.

One cell phone plan costs $29.94 per month plus $.10 for MB of data. Another plan costs $32.99 per month
liubo4ka [24]
Plan 1 = 29.94 + 0.10x
Plan 2 = 32.99 + 0.05x

Plan 1 = Plan 2
29.94 + 0.10x = 32.99 + 0.05x
0.10x - 0.05x = 32.99 - 29.94
0.05x = 3.05
0.05x/0.05 = 3.05/0.05
x = 61

61 MB of data is needed to make both plan equal.

to check: x = 61

29.94 + 0.10(61) = 32.99 + 0.05(61)
29.94 + 6.10 = 32.99 + 3.05
36.04 = 36.04

This is an equation that calculates potential energy and converts the value into its commercial unit.

<u>Step-by-step explanation:</u>

Step 1:

Given equation is 2 kg × 9.81 m/s² × 40 m. From the units, find the corresponding measurements. kg is the unit of mass (m), 9.81 m/s² is the acceleration due to gravity (g) and m is the unit of length or height (h).

This shows that this equation is to find potential energy. It is then converted into the commercial unit of energy (Joules).

⇒ Potential Energy = mgh = 2 kg × 9.81 m/s² × 40 m

                                            = 784.8 kg m²/s²

                                            = 784.8 N-m (Since unit of force, 1 N=kg m/s²)

                                            = 784.8 J (1 Newton-m = 1 Joule)

Many people believe that the daily change of price of a company's stock on the stock market is a random variable with mean 0 and
Tomtit [17]

Answer:

Step-by-step explanation:

We can use normal aproximation, assuming that the random variables are a lot of that means the sample size is large.

P(x>105) = P(z>\frac{105-100}{1})=P(z>5)

Using the normal distribution table,

P(z>5) = 0.00005

Hence, we can conclude that the probability that the stock’s price will exceed 105 after 10 days is very small.

Hope this helps!

Determine whether the graph table or equation represents a linear or nonlinear function explain
Anna [14]
<h3>Answer: Linear</h3>

Each time x goes up by 3, y goes up by 2. The rate of change is constant.

slope = (change in y)/(change in x) = 2/3

y intercept = 6 since this is where x = 0

The equation of this line is y = (2/3)x+6
