Answer:
A
Step-by-step explanation:
It is A because it is very precise and it can make a bar graph.
Answer: Choice A) You ask 20 people what their favorite season is.
Choices B and C are best represented with a line graph to show the growth over time.
A bar graph is useful to see how many categories get a certain response. In the case of choice A, we have four categories for each season. The height of each bar represents how many responses were made for that given category.
Can someone figure this out??
Answer:
x = 6 2/3
Step-by-step explanation:
We can use ratios to solve
x/4 = 15/9
Using cross products
9x = 4*15
9x = 60
Divide each side by 9
x = 60/9
x = 20/3
x = 6 2/3
Find the length of AB
Answer:
17 units
Step-by-step explanation:
You can find the lenght of drawing a triangle and counting the x units and y units, thereby the AB would be the hypotenuse.
X units ( base ) = 15 units
Y units ( height ) = 8 units
AB = root of 8^2 + 15^2
AB = root of 289
AB = 17 units

Tickets for a high school football game cost $2.50 each if purchased in advance. They cost $3.75 each if bought at the gate on the day of the game. For a particular game , 250 tickets were sold at the gate. If the sales totaled $1750, how many tickets were sold in advance?
250*3.75=937.5
1750-937.5=812.5
812.5/2.5=325
325 tickets were sold in advance :)
Answer:
1,500 tickets were sold in advance.
Step-by-step explanation:
$ 1,750 - 250 tickets = 1,500 tickets
In a group of 28 students, 12 study both Art and Biology.
12 study Biology but not Art.
4 study neither subject.
Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?
Answer:
100%
Step-by-step explanation:
Use conditional probability:
P(B | A) = P(B and A) / P(A)
P(B | A) = (12/28) / P(A)
We need to find the probability that a student studies art.
P(A or B) = P(A) + P(B) − P(A and B)
24/28 = P(A) + (12+12)/28 − 12/28
P(A) = 12/28
P(B | A) = (12/28) / (12/28)
P(B | A) = 1
What this means is that all of the students who study art also study biology.

-6(x+2)=5(3x+6)
i wasn’t here when we did this
Answer:
x=-2
Step-by-step explanation:
-6(x+2)=5(3x+6)
-6x-12=15x+30 distribute the outside numbers
-6x=15x+42 add 12 on both sides
-21x = 42 subtract 15x on both sides
x=-2 divide by -21 on both sides.

Answer:
Step-by-step explanation:
GH bisects ∠FGI.
So, ∠HGI =∠FGH
6x - 17 = 5x - 8 {Add 17 to both sides}
6x = 5x - 8 + 17
6x = 5x + 9 {Subtract 5x form both sides}
6x - 5x = 9
a) x = 9
b) ∠FGH = 5* 9 - 8
= 45 - 8
∠FGH = 37
c) ∠HGI = 6*9 - 17
= 54 - 17
∠HGI = 37
d) ∠FGI = ∠FGH + ∠HGI
= 37 + 37
∠FGI = 74

Last week John’s hamster drank 45 mL of water. This week he drank 25 mL of water. By what percent did the hamster’s intake of water decreased?
Answer:
Percentage decrease is 55%.
Step-by-step explanation:
Given the following data;
Original (old) number = 45mL
New number = 20mL
[tex] Percentage \; decrease = \frac{change\; in \;amount}{original\;number} * 100[/tex]
Change in amount = 45 - 20 = 25
Substituting into the equation, we have;
[tex] Percentage \; decrease = \frac{25}{45} * 100[/tex]
[tex] Percentage \; decrease = 0.55 * 100[/tex]
[tex] Percentage \; decrease = 55%[/tex]
Therefore, the hamster’s intake of water decreased by 55%.

Write an absolute value inequality for the recommended air pressure range for each type of ball. Use the variable x for the ball's actual air pressure. Soccerball 12.05 recommended psi tolerance+3.55 Basketball 8.00 average recommended psi tolerance +0.5 volleyball 4.44 average recommended psi tolerance +0.18
Answer:
For Soccer ball:
x = | 12. 05 + 3.55 |
For basketball:
x = | 8.00 + 0.5 |
For volleyball:
x = | 4.44 + 0.18 |
Step-by-step explanation:
Given the following :
Let x = ball's actual air pressure
_________avg Recommended psi ___tolerance
Soccer ball____ 12. 05 ____________+3.55
Basketball _____8. 00_____________+0.5
Volleyball _____ 4.44 _____________ + 0.18
Actual air pressure = | average recommended psi + tolerance |
Hence ;
For Soccer ball:
x = | 12. 05 + 3.55 |
For basketball:
x = | 8.00 + 0.5 |
For volleyball:
x = | 4.44 + 0.18 |

Step-by-step explanation:
2x - 1y = -9
y = - 5 - 5x
Answer:
x = - 7 and y = 30
Step-by-step explanation:
2x - y = -9
subtract 2x from either side
-y = -9 - 2x
divide either side by -1
y = 9 + 2x
Plug in 9 + 2x for y
9 + 2x = -5 - 5x
Add 5 to either side and subtract 2x from either side
14 = -2x
divide either side by -2
-7 = x
plug in -7 for x in one of the equations
y = -5 - ( 5 x -7 )
y = -5 - ( - 35)
y = -5 + 35
y = 30
plug in x and y
30 = -5 - ( 5 x -7)
30 = -5 - (-35)
30 = -5 + 35
30 = 30
Answer:
B. −19
Step-by-step explanation:
Multiply both sides of the equation by y , and then isolate the variable.
y−1y
=
10
y−1
=
10y
−1
=
9y
−19
=
y
Divide both sides by 9
John was 40" tall in 2008 and 46" tall in 2010. Dave was 53" tall in 2003 and 70" tall in 2007. Who is growing at
a faster rate? If each person keeps growing at the same rate, how tall can we expect each to be in 2011? Is this
a reasonable expectation?
Answer:
John is growing at a faster rate.
Step-by-step explanation:
John grew 6 inches in 2 years, while Dave grew 7 inches in 4 years. We can expect John to grow another 3 inches by 2011, making John 49 inches tall in 2011. We can expect Dave to grow about another 7 inches by 2011, since another 4 years has passed. This seems reasonable enough...
