The probability that Jordan misses a free throw is 0.16
How to determine the probability that he misses?From the question, we have the following parameters that can be used in our computation:
Odds in favour = 21 : 4
Represent the odds as a fraction
So, we have the following representation
Odds in favour = 21/4
To convert the odds to probability, we make use of the following equation
Probability = Numerator/(Numerator + Denominator)
Substitute the known values in the above equation, so, we have the following representation
Probability = 21/(21 +4)
Evaluate the sum
Probability = 21/25
The probability that he misses is
Misses = 1 - 21/25
Evaluate the probability
Misses = 4/25
So, we have
Misses = 0.16
Hence, the probability is 0.16

Graph the piecewise function.
Answer:
see attached
Step-by-step explanation:
You want a graph of the piecewise function ...
[tex]f(x)=\begin{cases}x&\text{if $x\le -1$}\\-3x+2&\text{if $-1 < x < 4$}\\4&\text{if $x\ge 4$}\end{cases}[/tex]
GraphThe graph is attached.
For x ≤ -1, the graph is a line with slope 1. If it were allowed to continue, it would pass through the origin. It terminates in a closed dot at (-1, -1)
For -1 < x < 4, the graph is a line with slope -3 through point (0, 2) on the y-axis. It has open circles at both ends, at points (-1, 5) and (4, -10).
For x ≥ 4, the line is horizontal at y=4. It has a closed dot at (4, 4).
__
Additional comment
The dot at the end of an interval is closed if the "or equal to" case is included (≤ or ≥). If it is not (< or >), then the dot is an open circle.
The slope is the ratio of "rise" to "run". It is the number of grid squares the line moves up (+) or down (-) for each grid square to the right.

Solve for y given that the height of the triangle is 4 miles and each of the legs are 7 miles.
Answer:
Step-by-step explanation:
x^2 + y^2 = z^2 is the pythagorean theorem.
If you divide the large triangle into two separate ones, with sides 7, 4 and 0.5y, you can use the pythagorean theorem to figure out 0.5y. So:
7^2 = 4^2 +(0.5y)^2
49-16 = 33

In tryouts for the olympics, a speed skater had times of 44. 64, 43. 45, 42. 79, and 42. 28 seconds. Find the average time. (hint: add the numbers and divide by 4. ).
The average time of the Olympic speedskated is 43.29 units.
What do we mean by average?An average, which is frequently the sum of the numbers divided by the total number of the numbers in the group, is a single number that is selected to describe a group of numbers in simple English.
For example, the average of the numbers 2, 3, 4, 7, and 9 is 5.
The four sorts of averages that we recognize are mean, mode, median, and range.
Although the others are our most popular "measures of central tendency," range is actually a measure of spread or distribution.
So, the average time is calculated as follows:
We have: Time: 44.64,43.45,42.79 and 42.28
The formula for average mean: ∑ₓ/n
Where ∑ₓ is the sum of observations and n is the number of observations.
Now, calculate the average time:
Average = 44.64+43.45+42.79+42.28/4
Average = 173.16/4
Average = 43.29
Therefore, the average time of the Olympic speedskated is 43.29 units.

(A) Prove that the opposite sides of the rectangle are congruent.
Use Distance Formula: v(x2 - x1)^2 + (y2 - y1)^2
(B) Prove the diagonals of your rectangle are congruent.
(C) Using the slopes for each side, prove there are 4 right angles on the rectangle.
**Please Show All Work**
A. Using the distance formula, we can state that the opposite sides are congruent because AD = BC = √10 units and AB = CD = √40 units.
B. The diagonals are equal, AC = BD = √50 units.
C. Based on the slopes of each side, there are 4 right angles on the rectangle.
What is the Distance Formula?The distance formula is used to find the distance that exist between tow points that are on a coordinate plane. The formula is: d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].
What is the Slope of a Line?
Slope = change in y / change in x.
A. The coordinates of each of the vertices of the rectangle are:
A(1, 2)
B(7, 4)
C(8, 1)
D(2, -1)
Use the distance formula to find AB, CD, BC, and AD.
AB = √[(7−1)² + (4−2)²]
AB = √40
CD = √[(2−8)² + (−1−1)²]
CD = √40
BC = √[(8−7)² + (1−4)²]
BC = √10
AD = √[(2−1)² + (−1−2)²]
AD = √10
Therefore, the opposite sides are congruent because AD = BC = √10 units and AB = CD = √40 units.
B. The diagonals are AC and BD. Find their lengths using the distance formula:
AC = √(8−1)² + (1−2)²]
AC = √50 units
BD = √[(2−7)² + (−1−4)²]
BD = √50 units
Therefore, the diagonals are equal, AC = BD = √50 units.
C. Find the slope of AB, CD, BC, and AD:
Slope of AB = change in y / change in x = rise/run = 2/6 = 1/3
Slope of CD = 2/6 = 1/3
Slope of BC = -3/1 = -3
Slope of AD = -3/1 = -3
-3 is the negative reciprocal to 1/3, this means that, if the two lines that meet at a corner have these two slope, then they will form a right angle because they are perpendicular to each other.
Therefore, there are 4 right angles on the rectangle.

Maya drove on the mountains for her trip. Due to traffic, her average rate of miles per hour was faster at the time of coming back to her home than going on her trip. Thus, The distance between where she lives and the mountains is
288 miles .
Let's consider that Maya live x miles from the mountains.
Let her rate to mountains be y miles/h.
we have given that
Driveing time taken by Maya going from home to trip location= 9 hours due to traffic
total return time taken by her = 4 hours
average rate = 40 miles/hour
Using rate formula,
Rate = distance/time
=> distance (d) = rate (r) × time (t)
so, x/y = 9
=> x=9y --(1)
Return trip 4 hours then rate = y+40
=> x/(y+40) =4 --(2)
using Substitution method, x= 3 substitute in (2)
=> 9y/(y+40)=4
=> 9y=4y+160
=> 9y-4y=160
=> 5y=160
=> y= 160/5
=> y=32
Now, x=9y
x=9×32= 288 miles
Hence, distance to the mountain is 288 miles.

"In a fruit salad, there are 12 strawberries, 14 grapes, and 4 mangos. Find the ratio of mangos to grapes. Write the ratio using a colon in the simplest form"
Answer:
The ratio of mangos to grapes is 2:7.
Step-by-step explanation:
The original ratio of mangos to grapes would be 4:14. When it says mangos to grapes, it means mangos first, then grapes. If it said grapes to mangos, the grapes would go first. But, in this case the mangos go first. Now, we don't worry about the strawberries because it says to find the ratio of mangos to grapes, which is 4:14. Now, it says to simplify it to the simplest form. So, we can do this by dividing both numbers by the same number down as far as they can go as a whole number (a number without a decimal):
4 ÷ 2 = 2
14 ÷ 2 = 7
So, this is as far as we can go. So, our final answer is 2:7.

Step-by-step explanation:
4 mangos for every 14 grapes
the ratio right now is 4:14 this can be simplified by dividing by 2
4 divided by 2 = 2 ( 2 x 2 = 4 )
14 divided by 4 = 7 ( 7 x 2= 14)
Now the ratio is 2:7, or 2 mangos for every 7 grapes we know this is right because in order to use the amount the recipe calls for you need to double the answer

Step-by-step explanation:
W -- X -- Y ----- Z
We are given that :
Y is the midpoint of WZ meaning that WY = YZX is the midpoint of WY meaning that WX = XY WY = 5Given this we want to find XZ
XZ consists of XY and YZ so we must find the length of the individual segments.
Finding YZ
Here, we know that YZ = WY as y is the midpoint of WZ. If WY = 5 then YZ also = 5
Finding XY
Given that WY = 5 and that X is a midpoint of WY we know that the segments WX and XY = WY and are congruent.
In other words we can say that 2XY = WY
==> WY = 5
2XY = 5
==> divide both sides by 2
XY = 2.5
Finding XZ
Again, XY + YZ = XZ
We have XY = 2.5 and YZ = 5
Hence, 2.5 + 5 = XZ
XZ = 7.5
Answer:
XZ = 7.5
Step-by-step explanation:
A drawing is sometimes very helpful.
Start by drawing a segment with endpoints W and Z.
+--------------------------------------------+
W Z
Y is the midpoint of WZ. Draw point Y in between W and Z and the same distance from both W and Z.
+---------------------+--------------------+
W Y Z
X is the midpoint of WY. Draw X between W and Y, and the same distance to W and Y.
+----------+----------+--------------------+
W X Y Z
Because of the midpoints, we know that:
WX = XY
WY = YZ
WY = 5
WX and XY are each half of WY, so WX = XY = 5/2 = 2.5
WY = YZ = 5
XZ = XY + YZ
XZ = 2.5 + 5
XZ = 7.5

The linear equation written in the slope-intercept form is:
y = -x - 5
How to find the slope?A linear equation can be written in the slope-intercept form as:
y = m*x + b
Where m is the slope and b is the y-intercept.
Particularly, if the line passes through the points (x₁, y₁) and (x₂, y₂) then the slope of the line is written as:
m = (y₂ - y₁)/(x₂ - x₁)
Here we can use the first two points on the table (or any you want) to find the slope:
(-1, -4) and (3, -8)
m = (-8 + 4)/(3 + 1) = -1
The slope is -1, so the line is something like:
y = -x + b
To find the value of b we can use another of the points on the table, if we use (7, -12) then we must have:
