Answer:
exponentialis+∞-∞Step-by-step explanation:
Neither linear nor exponential functions have a "wiggle" in their graph, so the piece in the region x < 0 is polynomial.
The piece in the interval [0, 3] is concave upward and has increasing slope. It could be polynomial, but is most likely the exponential piece of the function.
For x > 3, the function is linear.
There are no gaps in function value where the transition is made from one piece to another, so the function is continuous.
The function tends upward at the right side of the graph. It tends downward at the left side of the graph. This tells you the sign of the infinity they tend toward matches the sign of the infinity x tends toward.
__
On the interval [0, 3], h(x) is represented by an exponential function.
H(x) is a continuous function.
As x approaches +∞, h(x) approaches +∞.
As x approaches -∞, h(x) approaches -∞.
What is the Pythagorean triple generator and how does it work?
Answer:
Step-by-step explanation:
The Pythagorean Theorem states that
[tex]a^2+b^2=c^2[/tex]
or that the two legs added together squared equal the hypotenuse squared
not: this only works with right triangles
Now Pythagorean triples are the set of sides that follow that rule
an example would be 3,4,5
why is it a Pythagorean triple?
well because it follows
[tex]a^2+b^2=c^2[/tex]
[tex]3^2=9\\4^2=16\\16+9=25\\5^2=25[/tex]
25=25
Suppose that during a given week, 20 new customers have signed up for a specialized service your company provides. Eight of these new customers are automotive companies, and the remaining twelve are financial services firms. If a random sample of 5 of these new customers will be selected for a study of customer satisfaction in one month, what is the probability that 2 of the selected customers are financial services firms
Answer:
0.2384 = 23.84% probability that 2 of the selected customers are financial services firms
Step-by-step explanation:
The customers are chosen from a sample without replacement, which means that the hypergeometric distribution is used.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
20 new customers have signed up for a specialized service your company provides.
This means that [tex]N = 20[/tex]
Twelve are financial services firms.
This means that [tex]k = 12[/tex]
Sample of 5
This means that [tex]n = 5[/tex]
What is the probability that 2 of the selected customers are financial services firms
This is P(X = 2).
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 2) = h(2,20,5,12) = \frac{C_{12,2}*C_{8,3}}{C_{20,5}} = 0.2384[/tex]
0.2384 = 23.84% probability that 2 of the selected customers are financial services firms

205 1/5 is your answer
Step-by-step explanation:
break down the 3-D figure
Find area of triangle A=1/2bh
=1/2(8 inch)(6 9/10inch)
=1/2(8 inch)(69/10 inch)
=138/5 square inch
then multiply two because you have 2 triangles
=138/5 (2)
= 276/5 square inch
= 55 1/5 sq.in
Find area of rectangle
A = lw
=6 1/4 in (8 in)
= 25/4 (8 in.)
= 50 sq. in.
then multiply by 3 because of the three rectangles
= 50 sq. inch (3)
= 150 sq. in.
Add all together
55 1/5 sq. inch + 150 sq. inch = 205 1/5 sq. inch

John rides his motorcycle for 2.1 hours with a constant speed of 37 mph
and then for another 3 hours 28 minutes with a constant speed of 57 mph.
What is his average speed for the total trip?
Answer:
49.45mph
Step-by-step explanation
3 hours 28 min needs to be changed to decimal form so to do that we take 28/60 to get .466 so the new time for the second part of the trip is 3.466 hours.
from their you can add the distances of each part of the trip and divide that by the total time to get your average speed of 49.45mph
((rate1 x time1) + (rate2 x time2)) / (time1 + time2)
((37 x 2.1) + (57 x 3.466)) / (2.1 + 3.466)
(77.7 + 197.562)/ (5.566)
49.45mph
50 POINTS IF YOU HELP ME!!!!!! A study of college business majors included 150 sophomores and 200 juniors. The study showed that 80 sophomores and 150 juniors had summer internships. One person from the study is selected at random. What is the probability that the person is a sophomore given that the person had a summer internship? A. 8 23 3 B. C. 8 15 23 D. 35
Answer:
= 0.3478
Step-by-step explanation:
Given:-
- The number of sophomore, S = 150
- The sophomore and had summer internship, x = 80
- The number of juniors, J = 200
- The junior and had summer internship, y = 150
Find:-
What is the probability that the person is a sophomore given that the person had a summer internship?
Solution:-
- The total sum of sophomore and junior students is N:
N = S + J
N = 150 + 200
N = 350 students.
- We will denote event A as random selection of sophomore from total.
- We will denote event B as random selection of student who had summer internship.
- We are to determine the conditional probability that a person selected is sophomore given that the person had a summer internship. That is the probability of event A given that event B has already occured.
- The conditional probability can be written as:
P ( A / B ) = P ( A & B ) / P ( B )
Where,
P ( A & B ) : The probability the person is a sophomore and had a summer internship.
P ( B ): The probability that the person selected had a summer internship.
P ( A & B ) = x / N
= 80 / 350
= 0.22857143
P ( B ) = ( x + y ) / N
= ( 80 + 150 ) / 350 = 230/350
= 0.65714286
Therefore the required probability is:
P ( A / B ) = 0.22857143 / 0.65714286
= 0.3478 ... Answer
the answer to your question is = 0.3478
On Saturday and Sunday jarrod went running and burned a total of 6475 calories he burned 320 of those calories on Saturday which addition equation could be used to find the number of calories c jarrod burned on Sunday
A 647.5+c=320
B. 320 + c = 647.5
C. 320 + 647.5=c
D. 647.5 + 320 =c
Answer:
The answer is B.
Step-by-step explanation:
It is saying that 647.5 calories is the total amount and 320 is a part of it. so when you do 647.5-320, it becomes 327.5 and that is c. You can only do this with the equation that letter B is saying.

Hey There!
so this is a parallelogram so opposite angles are congruent
So basically what i am saying is that angle P is congruent to angle R
So we need to solve for x
We know that angle P and angle Q are supplements meaning that they will add up to 180
so we setup the equation
[tex]180=3x+5+8x-12\\[/tex]
step 1 combine like terms
[tex]3x+8x=11x\\5-12=-7[/tex]
now we have
180=11x-7
step 2 add 7 to each side
180+7=187
-7+7 cancels out
now we have
187=11x
step 2 divide each side by 11
187/11=17
x=17
now we plug in 17 to (3x+5) to get the value of angle R
17x3=51
51+5=56
therefore m∠R = 56

Answer:
C. 100°
Step-by-step explanation:
Line n || Line p and line t is their transversal.
Therefore,
[tex]m \angle 8 = 100 \degree \\ (corresponding \: \angle s)[/tex]
The measure of the angle ∠8 will be 100°. Then the correct option is C.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Two parallel lines are cut by a transversal.
Alternate angle - If two lines are parallel then the third line will make z -angle and z-angles are equal angles with the parallel lines.
The angle 4 and angle 5 are alternate angles.
∠5 = ∠4
∠5 = 100°
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
The angle 8 and angle 5 are vertically opposite angles.
∠8 = ∠5
∠8 = 100°
Thus, the measure of the angle ∠8 will be 100°.
Then the correct option is C.

Answer:
See step by step explanation
Step-by-step explanation:
Matching the vocabulary word with the correct definition, we get;
1. Axis of Rotation: a line around which a two-dimensional shape is rotated or revolved to create a three-dimensional shape.
It is a straight line through a rigid body when all its part are in rotation.
2. Cross section: the two-dimensional shape that results from cutting a three-dimensional shape with a plane. It is a internal view of an object that is made by cutting through it.
3. Solid of Revolution: the three-dimensional shape that is produced when a two-dimensional shape is rotated or revolved around a line. In mathematics, it is a solid shape that is obtained by revolving a curve around an axis.

a. Create a real world scenario of a study with a population mean and a population standard deviation. Include the information that a random sample of a given size (greater than 30) was selected from the population.
b. Check the conditions for the assumptions about the sampling distribution.
c. Draw, label and describe the sampling distribution in context.
Answer:
The t-score has the same interpretation as the z-score. It measures how far in standard deviation units \stackrel{-}{x} is from its mean μ. For each sample size n, there is a different Student’s t-distribution. The degrees of freedom, n – 1, come from the calculation of the sample standard deviation s. Remember when we first calculated a sample standard deviation we divided the sum of the squared deviations by n − 1, but we used n deviations \left(x-\stackrel{-}{x}\text{values}\right) to calculate s. Because the sum of the deviations is zero, we can find the last deviation once we know the other n – 1 deviations. The other n – 1 deviations can change or vary freely. We call the number n – 1 the degrees of freedom (df) in recognition that one is lost in the calculations. The effect of losing a degree of freedom is that the t-value increases and the confidence interval increases in width.
Properties of the Student’s t- Distribution 0.05, 95% level of confidence, we find the t-value of 1.96 at infinite degrees of freedom.
