what's the answer? It's difficult to understand and my teacher doesn't really teach.
Answers
Step-by-step explanation:
So for questions 1 through 4, you're basically finding the number in the middle of the two letters. In question 1, D is above 7 on the number line and E is above 11. The mid-point would be 9.
For 5 and 6, we'll be using this formula: [tex](\frac{x_{1} + x_{2}}{2},\frac{y_{1} + y_{2}}{2})[/tex]
And now we just plug in the numbers from question 5 but it works the same way on 6 as well.
[tex](\frac{3 + 5}{2},\frac{1 + 3}{2})[/tex] => (8/2, 4/2)
Coordinate of the midpoint would be (4, 2).
Lastly, we follow this system in order to get the final answers:
(Answer below shown for question 7)
(x + 2)/2 = 5
x + 2 = 10
x = 8
(y + 0)/2 = 2
y + 0 = 4
y = 4
Missing endpoint is (8, 4)

The number of mini bottles required is; 68 mini bottles
How to convert units of measurement?
We are told that a mini bottle of water contains 8 ounces of water.
Now, we are told that you require 4¹/₄ = 4.25gallons of water.
Now from conversions, we know that;
1 gallon = 128 ounces
Thus; 4.25 gallons = 4.25 * 128 = 544 ounces
Since a mini bottle of water contains 8 ounces of water, then we can say that;

Fiona has a coupon for $3 off the price of her meal at a local fast food establishment. her favorite meal is on sale at a special rate of 10% off the combo price. if fiona paid $8.25 for her meal, before taxes, what was the original price of the meal?
Answers
The Original price of the meal was $12.16.
Discount Percent is defined as the discount given on the product per hundred .
For Example . if there is 10% discount on a price of $100.
The final amount will be $90.
Final amount paid by Fiona = $8.25
percentage discount = 10%
Let the original amount be x.
According to the question ;
x - 10% of x = 8.25
[tex]x-\frac{10}{100} *x=8.25\\ \\ \frac{100x-10x}{100} =8.25\\ \\ \frac{90x}{100} =8.25\\ \\ x=\frac{8.25*100}{90}\\ \\ x=\frac{825}{90} \\ \\ x=9.16[/tex]
Since Fiona also had a discount coupon of $3.
The original amount will be $9.16+$3=$12.16.
Therefore , The original price of the meal was $12.16.

The slope, rise over run, or change in over the change in of a line determines its rate of change. A graph's slope triangle or two points in a table can be used to compute the slope.
How far is it between the two locations?
By calculating the sum of the absolute values of the y-coordinates, you may determine the distance between two places in different quadrants with the same x-coordinates.
What does a line's slope indicate?
A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).
Describe slope using an example?
The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b. M represents the line's slope. B is the b in the location where the y-intercept is located (0, b). For instance, the slope and y-intercept of the equation y = 3x - 7 are 3 and 0, respectively.Learn more about slope

The table shows the distance traveled by 4 cycleists. Sort the speeds of the riders, in miles per hour, from slowest to fastest.
Answers
The speed from slowest to the fastest is Julio; Elana; Kevin; Lorena.
Given that a table shows the distance traveled by 4 cyclists as shown in attached images.
Speed is defined as . The rate at which an object changes position in any direction. Speed is measured as the ratio between distance and time traveled.
Firstly, we will calculate the speed of Elena.
The given distance is 20(1/2) mi or it can be written as 41/2mi and the time is 2(1/4) hr or 9/4hr.
Now, substitute the values in speed formula that is
Speed=Distance/Time
Speed=(41/2)/(9/4)
Speed=(41/2)×(4/9)
Speed=82/9 mi/hr.
Now, we will calculate its speed of Julio.
The given distance is 12(1/4) mi or it can be written as 49/4mi and the time is 1(1/2) hr or 3/2hr.
Now, substitute the values in speed formula that is
Speed=Distance/Time
Speed=(49/4)/(3/2)
Speed=(49/4)×(2/3)
Speed=49/6 mi/hr.
Further, we will calculate the speed of Kevin.
The given distance is 20(2/3) mi or it can be written as 62/3mi and the time is 1(2/3) hr or 5/3hr.
Now, substitute the values in speed formula that is
Speed=Distance/Time
Speed=(62/3)/(5/3)
Speed=(62/3)×(3/5)
Speed=62/5 mi/hr.
Furthermore, we will calculate the speed of Lorena.
The given distance is 33(1/4) mi or it can be written as 133/4mi and the time is 2(1/3) hr or 7/3hr.
Now, substitute the values in speed formula that is
Speed=Distance/Time
Speed=(133/4)/(7/3)
Speed=(133/4)×(3/7)
Speed=57/4 mi/hr.
Hence, the speeds from slowest to fastest from the given table is Julio; Elana; Kevin; Lorena.

Given that z is a standard normal random variable, what is the probability that -2.51 z -1.53?
Answers
Probability that -2.51 < z < -1.53 = 0.057
Given that z is a standard normal random variable. Then the z - values are given by the area under standard normal curve. It can be found from the standard normal tables.
Now probability that -2.51 < z < -1.53 = P( -2.51 < z < -1.53 )
= P( -2.51 < z < 0 ) - P( -1.53 < z < 0 )
= P( 0 < z < 2.51) - P( 0 < z < 1.53 ) [Since areas are equal for same positive and negative values]
P( 0 < z < 2.51) = 0.4940
P( 0 < z < 1.53) = 0.4370
[From the normal tables]
