What is the distance between the two points at(-3,8) and(-3,-7)
Answers
Answer:
\(\boxed {\boxed {\sf 15}}\)
Step-by-step explanation:
Distance is calculated using this formula:
\(d=\sqrt {(x_2-x_2)^2+(y_2-y_1)^2\)
where (x₁, y₁) and (x₂, y₂) are the points. We are given (-3,8) and (-3,7). Therefore;
\(x_1= -3 \\y_1= 8 \\x_2= -3 \\y_2= -7\)
Substitute the values into the formula.
\(d= \sqrt {(-3--3)^2+(-7-8)^2\)
Solve inside the parentheses.
-3 - - 3= -3+3= 0 -7 - 8 = -15\(d= \sqrt {(0)^2+(-15)^2\)
Solve the exponents.
0²=0*0= 0 -15²= -15*-15=225\(d=\sqrt {0+225\)
\(d=\sqrt {225\)\(d= \pm 15\)
A negative number for distance doesn't make sense, so the distance must be 15.

Your original grades on your exams were: 75, 85, 90, 90, 100, 75, 80, 100, 90. You retake the exams and now your scores are: 85, 85, 100, 90, 100, 85, 80, 100, 90. By how many percentage points did you improve your average score? Hint: Find the mean of both sets of data. Then find the difference between the two. Round to the nearest %.
Answers
Based on your original grades in your exams and the scores after you retake your exams, the percentage points you improved your average score by is 3.83%
How to find the percentage improvement?To find the percentage that you improved by, the first thing to do is to find your average score in the first exam:
= (75 + 85 + 90 + 90 + 100 + 75 + 80 + 100 + 90) / 9
= 785 / 9
= 87.22
The average score after the exam was retaken was:
= (85 + 85 + 100 + 90 + 100 + 85 + 80 + 100 + 90) / 9
= 815 / 9
= 90.56
The percentage increase is:
= (90.56 - 87.22) / 87.22 x 100%

The linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.
To determine the linear function with the same y-intercept as the graph, we need to find the equation of the line passing through the points (3, 4) and (5, 0).
First, let's find the slope of the line using the formula:
slope (m) = (change in y) / (change in x)
m = (0 - 4) / (5 - 3)
m = -4 / 2
m = -2
Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:
y - y1 = m(x - x1)
Using the point (3, 4) as our reference point, we have:
y - 4 = -2(x - 3)
Expanding the equation:
y - 4 = -2x + 6
Simplifying:
y = -2x + 10
Now, let's check the given options to find the linear function with the same y-intercept:
Option 1: The table with x-values (-3, -1, 1, 3) and y-values (-4, 2, 8, 14)
The y-intercept is not the same as the given line. So, this option is not correct.
Option 2: The table with x-values (-4, -2, 2, 4) and y-values (-26, -18, -2, 6)
The y-intercept is not the same as the given line. So, this option is not correct.
Option 3: The table with x-values (-5, -3, 3, 5) and y-values (-15, -11, 1, 5)
The y-intercept is the same as the given line (10). So, this option is correct.
Option 4: The table with x-values (-6, -4, 4, 6) and y-values (-26, -14, 34, 46)
The y-intercept is not the same as the given line. So, this option is not correct.
Therefore, the linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

The ESS Ravens bought pizza for $900 to sell at the football game. They kept 10 pizzas to feed the players after the game and sold the rest for $1040. There were 8 slices in each pizza. Their profit was 50 cents a slice.
a) How many pizzas were in the original order?
Answers
Answer: 45
Step-by-step explanation:
The total profit in all was \(1040-900=\$ 140\).
The total profit per pizza was \((0.50)(8)=\$4\).
This means they sold \(\frac{140}{4}=35\) pizzas.
Adding this to the 10 pizzas held back, there were \(35+10=45\) pizzas in the original order.

the perimeter of an athletic field is 352 m. if the width is 68 m, find the length. write your answer as an integer or simplified fraction
Answers
Answer:
108
Step-by-step explanation:
p=2(l+w)
352=2(l+68)
352=2l+136
2l=352-136
2l=216
l=108
Formula of Perimeter of rectangle( P ) = 2 ( l + b )
Perimeter = 352m
Width = 68m
Length = ?
Now
Perimeter ( P ) = 2 ( l + b )
352m = 2 ( l + 68m )
352m = 2l + 136m
352m - 136m = 2l
216m = 2l
\(l \: = \frac{216m}{2} \\ \)
l = 108m

Shirley is drawing triangles that have the same area. The base of each triangle varies inversely with the height. What are the possible base and height of a second triangle if the first triangle's base is 14 and its height is 6?
Answers
The possible base and height of a second triangle are 12 and 7, respectively
How to determine the possible base and height of a second triangle?An inverse variation is represented as:
Base * Height = k
Where k is the constant of variation.
In this case, k is the area
So, we have:
Base * Height = Area
For the first triangle, we have:
14 * 6 = Area
Evaluate
Area = 84
Substitute Area = 84 in Base * Height = Area
Base * Height = 84
Express 84 as the product of two numbers
Base * Height = 12 * 7
By comparison;
Base =12 and Height = 7
Hence, the possible base and height of a second triangle are 12 and 7, respectively

a fair coin is flipped three times. what is the probability that the second flip is tails, given that there is at most one tails among the three flips
Answers
The probability that the second flip is tails, given that there is at most one tail among the three flips, is 1/3.
To find the probability, we need to consider all the possible outcomes that meet the condition of having at most one tails. There are three possible outcomes that meet this condition: heads-heads-heads, heads-tails-heads, and tails-heads-heads. Out of these three outcomes, only one of them, tails-heads-heads, has tails as the second flip.
Therefore, the probability of the second flip being tails, given that there is at most one tail among the three flips, is 1/3.
Mathematically, we can write this as:
P(second flip is tails | at most one tails) = P(tails-heads-heads) / P(at most one tails)P(tails-heads-heads) = 1/8 (since each flip has a 1/2 probability of being tails and the other two flips have to be heads)P(at most one tails) = P(heads-heads-heads) + P(tails-heads-heads) = 1/8 + 1/8 = 1/4 (since these are the only two possibilities for having at most one tails)Therefore,
P(second flip is tails | at most one tails) = 1/8 / 1/4 = 1/3.
