Answer:
A, B and C are the correct answers.
Step-by-step explanation:
Correct:
A - There are 4 even numbers all together. 2 is repeated twice, there is a 4 and a 6. 4 divided by 6 is 0.666 repeated. Multiply by 100 which gives you 66.666 repeated and then round up, so now we have 66.67%. This is the probability.
B - It’s impossible that the pointer will land on 1 because there in no 1.
C - It’s less likely because there are only two odd numbers, 3 and 5. Compare that to the 4 even numbers. 4 > 2. Therefore the odd numbers, or the two, is less likely than the even numbers, the 4.
Incorrect:
D - There is only one 6 out of 6 numbers total. So 1 out of 6. We cannot be certain, it fact, it would be said that it’s very unlikely for the pointer to land on the 6.
E - The spinner is most certainly not fair. The spinner has one of each number except for the 2. There are double twos. On a normal spinner you would see a number 1 replace on of the 2. This ways the spinner will be 1 through 6.
If it makes any of you more confident in this answer, my assessment also had this question and I got it correct by answering with A, B and C.
Final answer:
The probability of the pointer landing on an even-numbered section is 33.33%. The pointer can't land on 1. The spinner is not fair.
Explanation:
To find the probabilities in this scenario, we need to analyze the spinner. The spinner has 6 equal sections, numbered 2, 2, 3, 4, 5, and 6. There are:
2 even-numbered sections (2 and 4)3 odd-numbered sections (2, 3, and 5)1 section with a number less than 6 (4)Based on this analysis, we can determine the following statements:
Statement A is false: The probability of the pointer landing on an even-numbered section is 33.33% (2 out of 6 possibilities).Statement B is true: The pointer can't land on 1 because it is not one of the numbered sections on the spinner.Statement C is false: The probability of the pointer landing on an odd-numbered section is 50% (3 out of 6 possibilities), which is the same as the probability of landing on an even-numbered section.Statement D is true: The pointer will certainly land on a number less than 6 because all the numbered sections on the spinner are less than 6.Statement E is false: The spinner is not fair because the probabilities of landing on different sections are not equal.Fifteen less than twice a number x is y

Consider the two functions described below. Function 1 describes the cost, y, to park in a parking lot for x hours. There is a flat fee of $7.00 and $1.00 charge per hour. Function 2 is represented in the graph below. It shows the cost, y, to park in a parking garage, for x hours. Which statement correctly explains whether the parking lot or parking garage charges a higher rate per hour to park?
A. The parking lot charges a higher rate per hour because when you compare the rates, 7 4.
B. The parking garage charges a higher rate per hour because when you compare the rates, 2 1.
C. The parking lot charges a higher rate per hour because when you compare the rates, 7 2.
D. The parking garage charges a higher rate per hour because when you compare the rates, 4 1.
Statement B explains correctly that the parking garage charges a higher rate per hour than the parking lot. Statements B and D are the same.
Step-by-step explanation:
Step 1:
For the parking lot, there is a flat fee of $7.00 and then a charge of $1.00 every hour.
So if a vehicle was parked for 1 hour charges are 7 + 1 (1) = $8,
If parked for two hours charges are 7 + 1 (2) = $9.
Step 2;
To understand the pricing of the parking garage, we must plot the points of the graph.
The points on the graph are (0, 4), (1, 6), (2, 8), (3, 10), (4, 12), (5, 14)...
So for the parking garage, there is a flat fee of $4 and then a charge of $2.00 every hour.
So if a vehicle was parked for 1 hour charges are 4 + 2 (1) = $6,
If parked for two hours charges are 4 + 2 (2) = $8.
Step 3:
Comparing both the parking lot and the parking garage, we get that the flat fee for the parking lot is higher while the parking charges for an hour are higher for the parking garage which is statement B.
Statement B and D are the same.

3x - 5y = 8
3 (3x+4)
aytla
Answer:
See explanation
Step-by-step explanation:
Assuming your system is:
[tex]x + 3y = 4[/tex]
[tex]3x - 5y = 8[/tex]
Then make x the subject in the first equation to get:
[tex]x = 4 - 3y[/tex]
Put this equation into the second equation to get:
[tex]3(4 - 3y) - 5y = 8[/tex]
[tex]12 - 9y - 5y = 8[/tex]
[tex] - 9y - 5y = 8 - 12[/tex]
[tex] -14y = - 4[/tex]
[tex]y = \frac{ - 4}{ - 14} = \frac{2}{7} [/tex]
This means that:
[tex]x = 4 - 3 \times \frac{2}{7} [/tex]
[tex]x = 4 - \frac{6}{7} = \frac{22}{7} [/tex]
11/20+ c=3/4 what is the answer

Which formula is best used to prove that a figure has congruent sides?
a) Slope formula
b)Area formula
c) Midpoint formula
d) Distance formula
Answer:
D
Step-by-step explanation:
Congruent sides mean that they have "EQUAL" lengths.
So, to prove to sides are congruent means that their lengths are equal.
Slope gives the slope of a line. So this can't be it.
Area gives the area of figure. Nothing to do with congruency of 2 lines.
Midpoint formula gives the coordinates of the midpoint. Nothing here.
Distance formula gives the length of sides. So, this is the one we can use to prove that a figure has congruent sides. We can place the figure in coordinate system and find the length of 2 respective sides using "distance formula"
Correct answer is D
What is k over 3.5+7.4=8
Answer:
k=2.1
Step-by-step explanation:
k/3.5 + 7.4 = 8
Subtract 7.4 from each side
k/3.5 + 7.4 -7.4 = 8-7.4
k/3.5 = .6
Multiply each side by 3.5
k/3.5 *3.5 = .6 *3.5
k = 2.1
a sprinter increases the speed from 0 meters per second to 9 meters per second in 2 seconds. what is the acceleration
Answer:
The acceleration is
[tex]4.5 {ms}^{ - 2} [/tex]
Step-by-step explanation:
Use the equation of motion,
[tex]v = u + at[/tex]
where u=0m/s is the initial speed, v=9m/s is the final speed and t=2 seconds is the time.
We substitute the values into the equation and solve for the acceleration, a
[tex]9 = 0 + a(2)[/tex]
This means that;
[tex]9 = 2a[/tex]
Divide both sides by 2 to get:
[tex]a = \frac{9}{2} [/tex]
[tex]a = 4.5 {ms}^{ - 2} [/tex]

Find the values of the variables and the measures of the angles
The angles of the triangle are 39°, 51°, and 90°.
Step-by-step explanation:
Step 1:
The sum of all the angles in any triangle is equal to 180°.
We have two of the three angles in terms of x while the third angle is not given directly. Since it is a right-angled triangle, one of the angles equals 90°.
So the angles of the triangle are [tex]3x,[/tex] [tex]4x-1,[/tex] and [tex]90.[/tex]
Step 2:
Now, we substitute all the angles to a sum of 180 to determine the value of x.
[tex]3x + 4x - 1 + 90 = 180.[/tex]
[tex]7x = 91, x = \frac{91}{7} = 13.[/tex]
So x = 13°. The angles are
[tex]3x = 3 (13) = 39, 4x-1 = 4(13) - 1 = 51.[/tex]
The angles of the triangle are 39°, 51°, and 90°.
Step-by-step explanation:
3x + 4x - 1 = 90⁰
7x = 91
x = 13
Angles are = 39 , 51⁰

What is the decimal equivalent of an 11% increase
Answer:
0.11
Step-by-step explanation:
You would convert the percentage to a fraction. Since the % symbol means 'out of 100', you would put 11 over 100: 11/100.
Then you would convert the fraction to a decimal: 0.11.
An easier way could also be to take the percentage and move it two decimal places to the right.
Ex: 43% moved two decimal places to the right would be 0.43.
I hope this helps!
Answer:
0.11
Step-by-step explanation:
On the number line, a bug A is moving in the positive direction from the point 0, and a bug Bis moving in the negative direction from the point 0. The speeds of both bugs are constant. Both leave 0 at the same time, and three seconds later A has reached 18 and B has reached –15.
If x is the point reached by A after t seconds, and y is the point reached by Bafter t seconds, express x and y in terms of t.
Answer:
[tex]x=st[/tex]
[tex]y=-5t[/tex]
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
so
The distance is equal to multiply the speed by the time
Let
s ----> the speed in units per second
d ---> the distance in units
t ---> is the time in seconds
BUG A
we have
[tex]d=18\ units[/tex]
[tex]t=3\ sec[/tex]
The speed is equal to
[tex]s=\frac{d}{t}[/tex]
substitute
[tex]s=\frac{18}{3}=6\ units/sec[/tex]
If x is the point reached by A after t seconds
then
Multiply the speed by the time
[tex]x=st[/tex]
[tex]x=6t[/tex]
BUG B
we have
[tex]d=-15\ units[/tex]
[tex]t=3\ sec[/tex]
The speed is equal to
[tex]s=\frac{d}{t}[/tex]
substitute
[tex]s=\frac{15}{3}=5\ units/sec[/tex]
If y is the point reached by B after t seconds
then
Multiply the speed by the time
[tex]y=st[/tex]
[tex]y=-5t[/tex] ----> is negative because B is moving in the negative direction
Answer:
x = 6t
y = 5t
Step-by-step explanation:
We know the distance formula:
D = RT
Where
D is distance
R is speed
T is time
Bug A went 18 units after 3 seconds, so the speed is:
18 = R(3)
R = 18/3
R = 6 unit/sec
Bug B went 15 units in 3 seconds, so the speed is:
15 = R(3)
R = 15/3
R = 5 units/sec
x is reached by A after 3 seconds, so
x = 6t
y is reached by B after 3 seconds, so
y = 5t
A manufacturer uses 3/4 yard of fabric to make each skirt. How many yards of fabric will the manufacturer use to make 4 skirts ? 7 skirts ? 9 skirts
Answer:
3 yards,5.25 yard,6.75 yards
Step-by-step explanation:
Given,
Each skirt required 3/4 yards fabric
Solution,
1 skirt required fabric =3/4 yards
4 skirts required fabric=4×3/4 yards=3 yards
7 skirts required fabric =7×3/4 yards=21/4 yards=5.25 yards
9 skirts required fabric=9×3/4 yards=27/4 yards=6.75 yards
To find out how many yards of fabric will be used, multiply the number of skirts by the amount of fabric needed for each skirt. For 4 skirts, 3 yards of fabric will be used. For 7 skirts, 5.25 yards will be used. For 9 skirts, 6.75 yards will be used.
Explanation:To find out how many yards of fabric will be used to make a certain number of skirts, we can multiply the number of skirts by the amount of fabric needed for each skirt. In this case, 3/4 yard of fabric is needed for each skirt.
So, to find out how many yards of fabric will be used to make 4 skirts, we can multiply 4 by 3/4:
4 x 3/4 = 12/4 = 3 yards.
To find out how many yards of fabric will be used to make 7 skirts, we can multiply 7 by 3/4:
7 x 3/4 = 21/4 = 5.25 yards.
To find out how many yards of fabric will be used to make 9 skirts, we can multiply 9 by 3/4:
9 x 3/4 = 27/4 = 6.75 yards.
