an online article suggested for each additional person who took up regular running for exercise the number of cigarette smoke da

zzz [600]

The linear function that models the situation is given by:

$y = 45 - 0.178x$

The format of a<u> linear function</u> is:

$y = mx + b$

In which:

m is the slope, which is the rate of change.
b is the y-intercept, which is the initial value.

If nobody ran, 45 cigarettes would be smoked, thus the initial value is of $b = 45$ .
For each additional person that exercises, the amount decays by 0.178, thus the slope is $m = 0.178$ .

The equation that models this situation is:

$y = 45 - 0.178x$

What is the critical value t* which satisfies the condition that the t distribution with 14 degrees of freedom has probability 0

Oduvanchick [21]

Answer:

$t_{0.35,14}= 0.3933306$

Step-by-step explanation:

From the question we are told that:

Degree of freedom $df=14$

Significance Level $\alpha=0.35$

Generally the expression for critical value t is mathematically given by

$t_{\alpha,df}$

$t_{0.35,14}$

Therefore From Students T Value Table

$t_{0.35,14}= 0.3933306$

$T-Value (right-tailed): 0.3933306$

Lane went to the bookstore he spent 1/3 of his money on a pen and 4/6 of it on books what fraction of his money did he have left

Mumz [18]

Answer: I believe that it might be $1.00

Step-by-step explanation: Well the problem doesn’t tell you how much money he HAD, so if you do 1/3+4/6 you should get 6/6 or 1 as the amount that Lane had.

Using the given table of an exponential function, determine the growth/decay factor as well as the rate of increase/decrease. Ty

Westkost [7]

Answer:

The growth rate is 0.6

The growth factor is 1.6

Step-by-step explanation:

Generally, the exponential equation can be written as;

y = a(1 + r)^x

Where a is the initial value of 100

r is the growth rate

So let us form equations;

160 = 100(1 + r)^1 •••••(i)

Also;

256 = 100(1 + r)^2 •••••••(ii)

Divide equation ii by i

256/160 = 1 + r

1.6 = 1 + r

r = 1.6-1

r = 0.6
