At the end of the summer, Caitlin had saved $120 from her summer job. This was her initial deposit into a new savings account at

the bank. As the school year starts, Caitlin is going to deposit another $5 each week from her allowance. Is her account balance proportional to the number of weeks of deposits? Use the table below. (I would show you one, but I don't know how) Explain your reasoning.

<span>Let x = represent the number of weeks of deposits
A = 120 + 5x the account balance after x weeks
The account balance is directly proportional to the number of weeks of deposits if:
A/x = constant
(120 + 5x)/x = 120/x + 5 is not a constant
For example:
After 1 week there will be: 120 + 1*5 = $125 on the account
After 2 week there will be: 120 + 2*5 = $130 on the account
After 3 week there will be: 120 + 3*5 = $135 on the account
But 125/1 <> 130/2 <> 135/3
The account balance is not proportional to the number of weeks of deposits.</span>

Answer:

P(n>55)=0.1357

Step-by-step explanation:

From the question we are told that:

Sample size n=100

Sample space n'=36

Generally the equation for the mean number of times odds appears is mathematically given by

\=x_o=hp

\=x_o=100*0.5

\=x_o=50

Generally the equation for standard deviation is mathematically given by

\sigma=(hp(1-p))^{1/2}\\\sigma=(50(0.5))^{1/2}

\sigma=5

Therefore probability to make wrong decision P(n>55)

P(n>55)=1-P(z55)=1-P(z55)=1-0.86

P(n>55)=0.1357

A road is made in such a way that the center of the road is higher off the ground than the sides of the road, in order to allow
Jet001 [13]

Remark.

The problem is a bit indistinct. Where exactly are the two edges of the road? I'm going to say that they are the x intercepts, but that may not be true. Certainly it does not have to be true at all.


Graph.

A graph has been made for you. The maximum is marked for you. It is an approximation The actual height can be more accurately found.


Height

y = (-1/200)(x - 16)(x + 16)

y = (-1/200)*(x^2 - 256)


The maximum height for this graph only is when x = 0.Other graphs require completing the square.


y = (-1/200) * (-256)

y = 1.28 exactly. I thought the graph might be rounding the answer. It is not.
