Which of the following functions represent exponential decay? f(x)=3(1.7)^x-2
f(x)=3(1.7)^-2x
F(x)=3^5(1/4)^x
F(x)=3^5(2)^-x
Answers
Answer:
F(x)=3^5(1/4)^x
Step-by-step explanation:
By the exponential decay definition: y = ab×
b determines the rate at which the graph grows: if b > 1, the function will increase. if 0 < b < 1, the function will decrease.
There is only (1/4)ˣ : where 0<1/4<1 fit the definition, so F(x)=3^5(1/4)^x is the choice
----------------------------------------------------------------------------------------------------------
But.. look at the table attached, the f(x)=3(1.7)^-2x and F(x)=3^5(2)^-x also showed pattern of decay. It can verified from their graphs. (Try plot it with your calculator)

What is the slope between (-14,-12),(7,17)
Answers
Answer:
[tex]let, slope=m[/tex]
[tex]Therefore,m = 29 / 21 = 1.38095[/tex]
Answer:
Slope ≈ 1.38
Step-by-step explanation:
GIVEN :-
(x₁ , y₁) = (-14 , -12)(x₂ , y₂) = (7 , 17)TO FIND :-
Slope between the given pointsSOLUTION :-
Formula for slope = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Using this formula ,
[tex]Slope = \frac{17 - (-12)}{7 - (-14)}[/tex]
[tex]= \frac{17 + 12}{7 + 14}[/tex]
[tex]= \frac{29}{21}[/tex]
[tex]= 1.38 (appx.)[/tex]
A politician claims that he is supported by a clear majority of voters. In a recent survey, 38 out of 60 randomly selected voters indicated that they would vote for the politician. (You may find it useful to reference the z table.)
a. Select the null and the alternative hypotheses.
multiple choice 1
H0: p = 0.50; HA: p ≠ 0.50
H0: p ≤ 0.50; HA: p > 0.50
H0: p ≥ 0.50; HA: p < 0.50
b. Calculate the sample proportion. (Round your answer to 2 decimal places.)
c. Calculate the value of test statistic. (Round final answer to 2 decimal places.)
d. Find the p-value.
multiple choice 2
0.025 p-value < 0.05
0.05 p-value < 0.10
p-value 0.10
p-value < 0.01
0.01 p-value < 0.025
e. At the 5% level of significance, what is the conclusion?
multiple choice 3
Do not reject H0; the politician’s claim is not supported by the data.
Do not reject H0; the politician’s claim is supported by the data.
Reject H0; the politician’s claim is not supported by the data.
Reject H0; the politician’s claim is supported by the data.
Answers
Testing the hypothesis for the proportion, it is found that:
a) H0: p ≤ 0.50; HA: p > 0.50
b) The sample proportion is [tex]\pi = 0.6333[/tex].
c) The test statistic is [tex]z = 2.07[/tex].
d) The p-value of the test is of 0.0192.
e) Reject H0; the politician’s claim is supported by the data.
Item a:
At the null hypothesis, we test that the politician does not have the majority, thus:
[tex]H_0: p \leq 0.5[/tex]
At the alternative hypothesis, we test that he/she does have the majority, thus:
[tex]H_1: p > 0.5[/tex]
Item b:
38 out of 60, thus:
[tex]\pi = \frac{38}{60} = 0.6333[/tex]
The sample proportion is [tex]\pi = 0.6333[/tex].
Item c:
The test statistic is:
[tex]z = \frac{\pi - p}{\sqrt{\frac{p(1 - p)}{n}}}[/tex]
For this problem, [tex]\pi = 0.6333, p = 0.5, n = 60[/tex], thus:
[tex]z = \frac{0.6333 - 0.5}{\sqrt{\frac{0.5(0.5)}{60}}}[/tex]
[tex]z = 2.07[/tex]
The test statistic is [tex]z = 2.07[/tex].
Item d:
The p-value of the test is the probability of finding a sample proportion above 0.6333, which is 1 subtracted by the p-value of z = 2.07.
Looking at the z-table, z = 2.07 has a p-value of 0.9808.
1 - 0.9808 = 0.0192
The p-value of the test is of 0.0192.
Item e:
The p-value of the test is of 0.0192 < 0.05, thus, his claim is supported by the data, and we reject the null hypothesis. Then, the correct option is:
Reject H0; the politician’s claim is supported by the data.

y=mx+b m= rise/run = change in Y/change in x/ b= y-intecept.
Answers
Answer:
y = -[tex]\frac{2}{8}[/tex] + 5
Step-by-step explanation:
You have all that you need
(y = mx+b, m= rise/run which is the change in y/change in x, b = y-intercept.)
so now we just need to put it to use!
Let's take y = mx + b and break it into two parts. We need the b and the m. The b is easier, because we can conclude by looking at the graph it is equal too 5. Here is our equation so far:
y = mx + 5
Now we need to solve for m:
[tex]\frac{rise}{run} = \frac{2}{8}[/tex]
The line is going dowards, so the slope (m) is negative.
Here is our final answer:
y = -[tex]\frac{2}{8}[/tex] + 5

A group consisting of 6 people is to be selected from eight parents and four teachers.
Find the probability of selecting three parents and three teachers.
Answers
Answer:
9/32 or 0.28125
Step-by-step explanation:
8 parents and 4 teachers
There are 12 possible outcomes.
probability = # of favorable outcomes / # of possible outcomes
Let's do the teachers first.
There are 4 teachers, and we are finding the probability for 3 of them being picked.
Therefore,
P = 3/4
Now let's do the parents.
There are 8 parents, and we want 3.
Therefore,
P = 3/8
Now, we do [tex]\frac{3}{4} *\frac{3}{8} = \frac{9}{32}[/tex]
Therefore, the chance of 3 teachers and 3 parents being picked out of 4 teachers and 8 parents is 9/32, or in decimal form 0.28125.

Answer:

Step-by-step explanation:
The absolute value function has its vertex at (1, 3). It is scaled by a factor of -2, so its transformation of the parent function f(x) = |x| will be ...
-2f(x -1) +3 = -2|x -1| +3
This represents the left side of the equation you're seeking.
The right side equation is the equation of a line with slope 2/5 and y-intercept -2.2 = -11/5.
The equation that has both the left side and the right side correct is ...

What is the original size of the bottle?
Round your answer to the nearest tenth
Answers
The original size of the bottle is 17.5 ounces.
The soap manufacturer has increased the size of his bottles. This means that 18.4 ounce bottle is bigger than the original size of the bottle. The bottle was increased by 5%, this means that the new bottle is 105% (100% + 5%) bigger than the initial size of the bottle.
To determine the original size of the bottle, this formula would be used:
New bottle size / total percentage increase in the bottle = initial size of the bottle
18.4 / 1.05 = 17.5 ounces
