Answer:
27
Step-by-step explanation:
We know the missing angle for the triangle on the left is 63. And that is the same angle reflected to the other side. There is a right angle so its 63 + 90 = 157.
180 - 157 = 27
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

Question 4
Jada makes sparkling juice by mixing 2 cups of sparkling water with every 3 cups of apple juice.
How much sparkling water does Jada need if she uses 15 cups of apple juice?
HURRY
Answer:
9
Explanation:
Hope it helps.. I got it right
Answer:
You multiply the 2 by 3 to get the 6 cups of sparkling water, so you then multiply the 3 cups of apple juice by 3 to keep the ratio the same. 3 · 3 = 9. Jada uses 9 cups of apple juice.

Bob's Bagels sells 10 bagels for $11.00, and Donny's Bagels sells 4 bagels for $3.00. Which is the better deal?
Answer the questions to find out.
1. Will the better deal have a lower or higher ratio of dollars per bagel?
2. What fractions do you compare to find the better deal? How did you know to pick those?
3. Which store has the better deal, Bob's Bagels or Donny's Bagels? Explain how you know
Answer:
3. Bob's Bagels is a better deal than Donny's Bagels because you get more bagels for less money at Bobs than Donnys. At Donnys Bagels you only get 4 bagels and you have to pay more. I hope that helps.

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

2(5x - 20) - (15 + 8x) = 7
Answer:
x=31
Step-by-step explanation:
10x -40 -15-8x=7
2x - 40 -15 =7
2x -55 =7
2x-55+55 = 7 + 55
2x=62
2x/2=62/2
x=31
Step-by-step explanation:
10x-40-15+8x=7
2x-55=7
2x=7+55
2x=62
X=31

What is the answer 1/2 x 2 1/3
Answer:

Step-by-step explanation:
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

please help me. In the circle below, U is the center, VX is a diameter, and m VW = 110 degrees Use this information to fill in the blanks.
Answer:
Step-by-step explanation:
Inscribed angle → ∠VXY
(Angle included between two chords meeting at a point on circumference)
Minor arc → (arc VY)
(Arc measuring less than 180° is called as minor arc)
Semicircle → (arc VWX)
(Arc inscribed by the diameter)
m(arc VWX) = 180°
(Semicircle)
m(∠VUW) = 110°
(Central angle subtended by an arc)

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 -∞.
Need answer this urgent and fast
Answer:
56
Step-by-step explanation:
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

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
