The probability that all seven arrows will not hit the bullseye is 1 2/5
Probability calculate how likely it is for an event to occur. The chances of an event occurring is between 0 and 1. The value of the event is one if the event happens and zero if the event does not happen.
For example the probability that it would rain everyday of the week lies between 0 and 1. If it rains, a value of 1 would be attached to the event and if it does not rain all the days of the week a value of zero would be attached to the event.
Probability all seven arrows does not hit the bullseye = number of arrows x probability of one arrow not hitting the bullseye
Probability that one arrow does not hit the bullseye = 1 - 4/5
5/5 - 4/5 = 1/5
Probability = 1/5 x 7 = 7/5 = 1 2/5

what is the solution of 7k+2=4k-10?
Use one of the reasons from the box to justify each step.
You may use a reason more than once.
k=-4
7k+2=4K-10
+10 +10
7k+12=4K
-7k -7k
12=-3k
Divide both sides by -3
K=-4
The solution is k = -4.
To solve the linear equation 7k+2=4k-10, we need to isolate the variable k on one side of the equation. Here are the steps to simplify the equation and find the value of k:
Subtract 4k from both sides to eliminate the variable from the right side of the equation: 7k - 4k + 2 = 4k - 4k - 10, which simplifies to 3k + 2 = -10.
Subtract 2 from both sides to eliminate the constant term from the left side of the equation: 3k + 2 - 2 = -10 - 2, which simplifies to 3k = -12.
Divide both sides by 3 to solve for k: 3k / 3 = -12 / 3, which simplifies to k = -4.
Now we need to check the solution by substituting k = -4 back into the original equation to verify that it holds true:
7(-4) + 2 = 4(-4) - 10
-28 + 2 = -16 - 10
-26 = -26
The left and right sides of the equation are equal, confirming that k = -4 is the correct solution. Thus, the steps are justified and the solution is reasonable

Ameena's boat travels 35 miles per hour. The best fishing spot in the lake is 27 miles away from her starting point. If she drives her boat for 2/3 of an hour, will she make it to the best fishing spot on the lake?
Answer: No, she will not make it tot he best fishing spot on the lake.
Step-by-step explanation:
Since we have given that
Distance between the starting point and the best fishing spot = 27 miles
Speed at which Ameena drives = 35 miles per hour
Time she takes to drive her boat is given by
[tex]\frac{2}{3}\text{ of an hour}[/tex]
As we know that ,
[tex]Distance=Speed\times time\\\\Distance=35\times \frac{2}{3}\\\\Distance=\frac{70}{3}\\\\Distance=23.33\text{ miles}[/tex]
But we have given that the best fishing spot in the lake is 27 miles away from her starting point ,
[tex]\text{And with this speed in }\frac{2}{3}\text{ of an hour he reached only }23.33 \text{ miles. }[/tex]
So,
No, she will not make it tot he best fishing spot on the lake.
No, she will not
Find how far Ameena's boat will have traveled at two thirds of an hour.
(35 miles per hour) (2/3 of an hour)= 23.33 miles
Ameena's boat will have traveled just over 23 miles. She will not have reached the best fishing spot which will still be approximately another 4 miles away.
To find how far Ameena's boat has traveled you multiplied the speed by the time, but since time is now the unknown variable, divide the distance by the speed
27 miles divided by 35 miles per hour to get 0.77 hours
What is the conversion for hours to minutes?
0.77 = 46.2 minutes
Which statement is NOT one of the axioms of Euclidean geometry?
A.
Given any two distinct points, there is exactly one line that contains them.
B.
Every plane contains at least three points that do not lie on the same line.
C.
If two points lie in a plane, the line containing these points also lies in the plane.
D.
If two planes intersect, their intersection is a point.
Answer:
b
Step-by-step explanation:
B: Every plane contains at least three points that do not lie on the same line
To answer this question, we will have to state the 5 axioms of Euclidean geometry and they are;
1. A straight line could be drawn between any two points; This means that as long as there is no obstacle between the two points, then we can say that it is possible to draw a straight line between both points. However, if there is an obstacle between the two points, then it is not possible to draw a straight line.
2. Any straight line that is terminated could still be extended indefinitely; A line segment may be bound by an endpoint, but a straight line is not bounded by any endpoint and as a result, it can be extended indefinitely in both directions.
3. A circle could be drawn with any given center point and any given radius; If for example we use a line segment bounded by two end points. If we use one of these 2 endpoints to be the centre of a circle and make the radius of the circle to be equal to the length of the line segment earlier used as an example, it means if we draw a circle, it will have a diameter that is twice the length of that same line segment.
4. All right angles are definitely equal; A right angle always has a measurement of 90°. This means that regardless of its' orientation, it will still remain 90°.
5. For any given point that is not on a given line, there will be exactly one line passing through the point that would not meet that same given line; This implies that two lines will be parallel to each other if they intersect a third line with the interior angle between them being 180°.
Looking at the given options in the question, the only one that doesn't correspond to any of these 5 axioms I have stated would be option B.

in 2004, approxhnately 5 million cars and trucks were classified as fleX-fuel,
which means they could run on gasoline or ethanol. In 2016, that number increased to about 20 million. How many more cars and trucks were flex-fuel in 2016?
Approximately 15 million more cars and trucks were flex-fuel in 2016 compared to 2004.
Explanation:The number of flex-fuel cars and trucks in 2004 was approximately 5 million. In 2016, this number increased to about 20 million. To find out how many more cars and trucks were flex-fuel in 2016, we need to subtract the number of flex-fuel vehicles in 2004 from the number in 2016.
Number of flex-fuel vehicles in 2016: 20 million
Number of flex-fuel vehicles in 2004: 5 million
More flex-fuel vehicles in 2016 = Number of flex-fuel vehicles in 2016 - Number of flex-fuel vehicles in 2004
= 20 million - 5 million

Point B is at (4,-16).Where is B prime after a dilation with a scale factor of 3/4
After applying the dilation with a scale factor of 3/4, point B at (4,-16) will transform to B prime (B') at (3,-12).
Explanation:The point B is originally at (4,-16). In a dilation, each coordinate of the initial point is multiplied by the scale factor to obtain the coordinates of the transformed point. Here, the scale factor is 3/4. To find the coordinates of the point B prime (B') after the dilation, we multiply each coordinate of point B by 3/4:
X-coordinate of B' = 4 * (3/4) = 3
Y-coordinate of B' = -16 * (3/4) = -12
Therefore, the coordinates of B prime (B') after the dilation with a scale factor of 3/4 are (3, -12).

A bus averages 4 miles per hour faster than a motorcycle. If the bus travels 180 miles in the same time it takes the motorcycle to travel 156 miles, then what is the speed of each?
Set up equations:
(1) speedbus = speedbike+4
(2) speedbus/speedbike = 180/156
plug (2) into (1)
speedbike * 180/156 = speedbike + 4
(solve for speedbike)
speedbike = 4 / (180/156-1) = 26 mph

A container has 17 1/2 cups of lemonade. Asher gives each of his classmates 5/6 of a cup. He gives away all of the lemonade. How many classmates does Asher give lemonade to? Explain each st e by using first,next and last method
A container has 17 and 1/2 cups of lemonade.
Asher gives each of his classmates 5/6 of a cup.
He gives away all of the lemonade.
Solution:
There are 17.5 cups of lemonade.
Each classmate receives 5/6 of a cup.
So the number of classmates = Number of cups ÷ proportion of a cup each student receives
Number of classmates = 17.5 ÷ 5/6 = 21 classmates
There are 21 classmates.
Answer:
21 classmates.
Step-by-step explanation:
We have been given that a container has 17 1/2 cups of lemonade. Asher gives each of his classmates 5/6 of a cup.
To find the number of classmates that will get lemonade, we will divide total amount of lemonade by amount given to each classmate.
[tex]\text{Classmates that will get lemonade}=17\frac{1}{2}\div\frac{5}{6}[/tex]
Convert mixed fraction into improper fraction:
[tex]17\frac{1}{2}\Rightarrow=\frac{17\times 2+1}{2}=\frac{34+1}{2}=\frac{35}{2}[/tex]
[tex]\text{Classmates that will get lemonade}=\frac{35}{2}\div\frac{5}{6}[/tex]
Convert into multiplication problem by flipping the 2nd fraction:
[tex]\text{Classmates that will get lemonade}=\frac{35}{2}\times\frac{6}{5}[/tex]
[tex]\text{Classmates that will get lemonade}=\frac{7}{1}\times\frac{3}{1}[/tex]
[tex]\text{Classmates that will get lemonade}=7\times3[/tex]
[tex]\text{Classmates that will get lemonade}=21[/tex]
Therefore, Asher gave lemonade to 21 classmates.

is the difference of two positive rational number always positive? Explain
NO, the difference between two positive rational numbers is not always positive.
A rational number is any number that can be expressed as a fraction of two different integers and these integers in their fractional form are not equal to zero.
Now, let assume the two positive numbers are 8 and 12. In rational positive
number, the numbers will be: [tex]\mathbf{\dfrac{8}{1}}[/tex] and [tex]\mathbf{\dfrac{12}{1}}[/tex]
The difference between these two rational numbers will not be positive because 12 is a larger number than 8.
