In a blind taste test, 25 people chose brand A, 15 people chose brand B, and 10 people chose
brand C. There are 200 more people to be surveyed. Based on the data, which is most likely.
to happen?
About 10 more people will choose brand B than brand C.
About 30 more people will choose brand C.
About 30 more people will choose brand A than brand B.
About 100 more people will choose brand A.
Answer: About 100 more people will choose brand A.
Step-by-step explanation:
Number of people who chose brand A = 25
Number of people who chose brand B = 15
Number of people who chose brand C = 10
Total number of people = 25+10+15 = 50
Since there are 200 people left, we'll equate them based on the data given and this will be:
For A = 25/50 × 200 = 100
For B = 15/50 × 200 = 60
For C = 10/50 × 200 = 40
Therefore, about 100 more people will choose brand A.
Answer:
About 100 more people will choose brand A

Solve for the length of x
Answer:
[tex]\boxed {\boxed {\sf x\approx 63.7}}[/tex]
Step-by-step explanation:
This is a right triangle. We know this because there is a small square in the corner representing a 90 degree/right angle. Therefore, we can use the right triangle trigonometry ratios.
sinθ= opposite/hypotensue cosθ= adjacent/hypotenuse tanθ= opposite/adjacentWe are given angle A which measures 37 degrees.
Side BC which measures 48 is opposite angle A and the unknown side, x, is next to or adjacent to angle A.
We should use tangent.
[tex]tan \theta= \frac{opposite}{adjacent}}[/tex]
[tex]tan37= \frac {48}{x}[/tex]
Since we are solving for x, we must isolate the variable. First, cross multiply. Multiply the first numerator and the second denominator, then the first denominator and second numerator.
[tex]\frac {tan37}{1}=\frac {48}{x}[/tex]
[tex]tan37*x=48*1[/tex]
[tex]tan37*x= 48[/tex]
x is being multiplied by the tangent of 37. The inverse of multiplication is division, so we divide both sides by the tangent of 37.
[tex]\frac {tan37 *x}{tan37}=\frac{48}{tan37}[/tex]
[tex]x= \frac{48}{0.7535540501}}[/tex]
[tex]x=63.69815144[/tex]
Even though it is not specified, let's round to the nearest tenths place. The 9 in the hundredth place tells us to round the 6 up to a 7.
[tex]x\approx 63.7[/tex]
The unknown side is approximately 63.7 units long.

Each card in a set of cards has one of the letters from the word MATHEMATICS. The cards are shuffled. Suppose you draw a card from the set of cards, record the letter, return the card to the set, and shuffle the cards. You repeat this experiment 22 times. Would you expect the experimental probability of drawing a vowel to be the same as the theoretical probability? YES or NO and Explain you answer
Answer:
No
Step-by-step explanation:
Theoretical probability is the expected probability of anything. For example we expect a probability of 1/6 for each number when we roll a die .
Experimental Probability is the one that is obtained by the actual experimenting of rolling the die.
The theoretical probability is the example of perfect probability and experimental probability is the example of actual occurrence.
Their formulas are
Theoretical Probability = number of possible outcomes/ total number of possible outcomes
Experimental Probability = number of favorable outcomes/ total number of actual outcomes
If we a roll a fair die several times we may get 2 repeated number of times or any other number that is on the die.
So the experimental probability is bit different from the theoretical probability.
Now if the cards are shuffled and the experiment is repeated 22 times
experimental probability of drawing a vowel would not be the same as the theoretical probability because n is small.
If n→1000 or more
n→∞
According to K. Pearson or Buffon when n tends to infinity the theoretical probability becomes equal to experimental probability.
They experimented this on a coin and put forward their results.
If a vector V is in standard position and the tip of the vector corresponds to the point (a, b), then we can write the vector in component form as
Answer:
[tex]V = <a,b>[/tex]
Step-by-step explanation:
Given
[tex]P= (a,b)[/tex] --- Point
Required
Component of V
From the question, we understand that V is in standard position.
This implies that V starts at the origin (0,0) and ends at (a,b)
So, vector V is:
[tex]V = <P(a,b) - O(0,0)>[/tex]
This gives:
[tex]V = <a-0,b-0>[/tex]
[tex]V = <a,b>[/tex]

Parts for an automobile repair cost $173. The mechanic charges $32 per hour. If a person receives an estimate for at least $253 and at most $285 for fixing the car, what is the time interval that the mechanic will be working on the job?
Answer:
58
Step-by-step explanation:
The time interval for the mechanic for this job is at least 2 hours and 30 minutes or at most 3 hours and 30 minutes.
What is at least and at most concept ?At least means lower limit of a given contrast and at most means higher limit of a given contrast.
According to the given question parts for an automobile repair cost 173 dollars and the mechanic charges 32 dollars per hour.
Given the person receives a cost of at least 253 dollars.
∴ The mechanic's total rate is ( 253 - 173 ) dollars which is = 80 dollars.
Also given the mechanic charges 32 dollars per hour so the time mechanic work for is at least (80/32) hours which is = 2.5 hours or 2 hours and 30 minutes.
In the later case when the owner receives a bill of 285 dollars the total rate of mechanic is
= ( 285 - 173 ) dollars.
= 112 dollars.
So, the mechanic have worked for (112/32) hours which is
= 3.5 hours or 3 hours and 30 minutes.

In the first quarter of the game,the giants gained 5 yards,lost 13 yards,gained 2 yards,gained 6 yards and,unfortunately,lost 12 yards in their final play.
1.Use a number line to depict the Giants' activity in the first quarter.
2.Use addition only to illustrate the Giants' activity in the first quarter.
3.What was the net yardage for the Giants in the first quarter.
Answer:
5 + (-13) + 2 + 6 + (-12) ;
-12 yards
Step-by-step explanation:
5 yards gain = + 5
13 yard loss = - 13
2 yards gain = + 2
6 yards gain = + 6
12 yards loss = - 12
Using addition Rule :
5 + (-13) + 2 + 6 + (-12)
The net yardage :
5 - 13 + 2 + 6 - 12 = - 12

I’m not sure how to solve, what do I need to do??
Answer:
Step-by-step explanation:
It's helpful to draw it out, but you need a calculator for this.
You have the values of line b, line c, and angle C.
You can use sinC / c since you have C and c.
Solve for sinB by doing sinB/5.7 = sinC/8.6
you'll get the value of sinB, use inverse trig to solve for B (sin^-1)
Then you'll have the angle values for C and B. Add them, and subtract by 180 to find the angle measure of A.
Use the steps above to find a:
sinA (which u just found) / a = sinC (125) / c (8.6)
Hope this helps.

in
3.6 in.
A) 14.2 in
B) 16.8 in
C) 18.2 in
D) 20.1 in
See the diagram of the circumscribed polygon attached below:
Answer:
A. 14.2 in.
Step-by-step explanation:
Perimeter = 3.7 + 3.6 + 3.4 + 1.9 + g
Let's find g.
a = 1.9 in. (Tangents drawn from an external point of a circle are congruent)
b = 3.4 - 1.9 = 1.5 in.
b = c = 1.5 in. (Tangents drawn from an external point)
d = 3.6 - 1.5 = 2.1 in.
d = e = 2.1 in. (Tangents drawn from an external point)
f = 3.7 - 2.1 = 1.6 in.
f = g = 1.6 in. (Tangents drawn from an external point)
✔️Therefore,
Perimeter = 3.7 + 3.6 + 3.4 + 1.9 + 1.6 = 14.2 in.

The school that Sarawong goes to is selling tickets to a play. On the first
day of ticket sales the school sold 13 senior citizen tickets (s) and 5 child
tickets (c) for a total of $125. The school took in $85 on the second day
by selling 5 senior citizen tickets and 5 child tickets. What is the price
each of one senior citizen ticket and one child ticket?
Write the two equations to solve the system first. Use s for senior
citizens and use c for child. Show all work using the method you prefer.
Equations:
Answer:
12s + 5c = 125
5s + 5c = 85
price of senior citizen ticket = $5.71
price of a child's ticket = $11.29
Step-by-step explanation:
This question can be solved using simultaneous equation
12s + 5c = 125 equation 1
5s + 5c = 85 equation 2
subtract equation 1 from 1
7s == 40
s = 40/7 = 5.71
Substitute for s in equation 1
12(5.71) + 5c = 125
68.57 + 5c = 125
5c = 125 - 68.57
5c = 56.43
c =11.29
QU | RT. Find TU.
Help plz...No links!! I will report!!
Answer:
34
Step-by-step explanation:
We solve the above question using Triangle Proportionality Theorem
This states that:
TU : TS = QR : RS
TU/TS = QR/RS
TU = ?
TS= 17
RS = 13
QR = 26
Hence,
TU/7 = 26/13
Cross Multiply
13 × TU = 17 × 26
TU = 17 × 26/13
TU = 17 × 2
TU = 34
Therefore, TU = 14
