What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The graph of the exponential function f(x) are shown in figure.
Hence, We get;
The curve intersect the x axis at x = 1.
So, x-intercept is 1.
Hence, Statement A is false.
The curve intersect the y-axis at y= 3.
So, y intercept is 3.
Thus, Statement B is correct.
The curve tends toward infinity at y = -1.
So y = -1 asymptote of the function.
Thus, Statement C is correct.
The range of function is y > -1.
So range is not all real number.
Thus, statement D is incorrect.
The function is defined for x > -0.5. At x = 0.5 function tends toward infinity.
Thus, statement E is incorrect.
As we move from left to right on x-axis then function decreases.
So, The function shows decay.
Hence, The statement F is incorrect.
The value of function approaches -1 as value of x increase but does not cross -1 or touch the value y = -1.
So statement G is correct.
Thus, All the correct statement are,
B, C and G.

Answers
Answer:
Explained below.
Step-by-step explanation:
The complete question is:
Assume that we have two events, A and B, that are mutually exclusive. Assume further that we know P(A) = 0.30 and P(B) =0.40.
What is P(A and B)?
What is P(A | B)?
Is P(A | B) equal to P(A)?
Are events A and B dependent or independent?
A student in statistics argues that the concepts of mutually exclusive events and independent events are really the same, and that if events are mutually exclusive they must be independent. Is this statement accurate?
What general conclusion would you make about mutually exclusive and independent events given the results of this problem?
Solution:
The probability of the two events A and B are:
P(A) = 0.30 and P(B) =0.40
(a)
Compute the value of P (A ∩ B) as follows:
\(P(A\cap B)=0\)
This is because mutually exclusive events are those events that cannot occur together.
(b)
Compute the value of P (A | B) as follows:
\(P(A|B)=\frac{P(A\cap B)}{P(B)}=\frac{0}{0.40}=0\)
Thus, the value of P (A | B) is 0.
(c)
No, P (A | B) is not equal to the P (A).
(d)
As mentioned in part (a), mutually exclusive events are those events which cannot occur together.
That is, \(P(A\cap B)=0\).
Events A and B are independent if the chance of their concurrent happening is equivalent to the multiplication of their distinct probabilities.
That is, \(P(A\cap B)=P(A)\times P(B)\).
The concepts of mutually exclusive events and independent events are not the same.
(e)
As the it is provided that A and B are mutually exclusive events, we know that \(P(A\cap B)=0\).
Now compute the value of \(P(A)\times P(B)\) as follows:
\(P(A)\times P(B)=0.30\times 0.40=0.12\neq 0\)
Thus, the events A and B are not independent.
Thus, if two events are mutually exclusive events they cannot be independent.

a
26%
b

c
4.42%
d

Answer:
A
Step-by-step explanation:
\( \frac{16.98 - 12.56}{16.98} \times 100 = 26\)
Answer:
35.191083%
Step-by-step explanation:
12.56/100=0.1256 (1%)
That's one percent of 12.56. How much by 0.1256 (1% of 12.56) is 16.98 (rised price)?
I used a two-step equation to get the answer
x*0.1256 = 16.98 /0.1256 /0.1256Divide both sides to get
x = 135.191083Now just subtract 100 because that was the old value
135.191083 - 100 = 35.191083and you get 35.191083. Therefore, the answer is D.
What is the slope-intercept equation of a line with a slope of 3/4 and a y-intercept of 4.
Answers
Answer:
Equation: y - 3x/4 + 4
Step-by-step explanation:
using the formula:
y = mx + b ................where m is slope and y-intercept is bSo using the formula:
y - 3x/4 + 4Answer:
y = 3/4(x) + 4
Step-by-step explanation:
The slope-intercept equation of a line can be written as y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.
We are given the slope (m) as 3/4 and the y-intercept (b) as 4. Thus, when we plug in values of m and b, we get the equation of y = 3/4(x) + 4.

A data set of values has a mean of 45 and standard deviation of 5. The z-score for a point A is 0. The z-score for a point B is0.2. What are the values of point A and point B?
Answers
Solution:
Given;
A data set of values has a mean of 45 and standard deviation of 5.
The z-score for a point A is 0. The z-score for a point B is 0.2.
To find the values of A and B, we will apply the z-score formula, which is
\(\begin{gathered} z=\frac{x-\mu}{\sigma} \\ Where\text{ } \\ x\text{ is the observed value} \\ \mu\text{ is the mean} \\ \sigma\text{ is the standard deviation} \end{gathered}\)Where
\(\begin{gathered} \mu=45 \\ \sigma=5 \end{gathered}\)For the value of point A,
Where, z = 0 for point A
\(\begin{gathered} z=\frac{x-\mu}{\sigma} \\ 0=\frac{x-45}{5} \\ Crossmultiply \\ 5(0)=x-45 \\ 0=x-45 \\ x=45 \end{gathered}\)Hence, the value of point A is 45
For the value of point B,
Where, z = 0.2 for point B
\(\begin{gathered} z=\frac{x-\mu}{\sigma} \\ 0.2=\frac{x-45}{5} \\ Crossmultiply \\ 0.2(5)=x-45 \\ 1=x-45 \\ Collect\text{ like terms} \\ x=1+45=46 \\ x=46 \end{gathered}\)Hence, the value of point B is 46

Step-by-step explanation:
it seems you solved the tricky part yourself already.
just to be sure, let's do the first derivative here again.
the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...
f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =
= 3t⁴ + 18t³ + 24t² + 18t + 21
f'(t) = 12t³ + 54t² + 48t + 18
and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).
we simply put the input number (2) at every place of the input variable (t).
so,
f'(2) = 12×2³ + 54×2² + 48×2 + 18 = 96 + 216 + 96 + 18 =

The ESS Ravens bought pizza for $900 to sell at the football game. They kept 10 pizzas to feed the players after the game and sold the rest for $1040. There were 8 slices in each pizza. Their profit was 50 cents a slice.
a) How many pizzas were in the original order?
Answers
Answer: 45
Step-by-step explanation:
The total profit in all was \(1040-900=\$ 140\).
The total profit per pizza was \((0.50)(8)=\$4\).
This means they sold \(\frac{140}{4}=35\) pizzas.
Adding this to the 10 pizzas held back, there were \(35+10=45\) pizzas in the original order.
