Raul is practicing for baseball tryouts he wants to find how far he can hit a baseball he hits the ball 10 times and measures the distance the ball travels each time which measure should roll used to learn the average distance he hit the ball
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]n = 10[/tex] --- Number of tryouts
Required
Determine the average distance
This question has missing details, as the distance he hits the ball in each tryout is not given. However, I'll give a general explanation.
The mean is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\sum x[/tex] means the sum of the distance in each tryout.
Assume that the distance in the 10 tryouts are: [tex]6, 8, 5, 9, 4, 5, 8, 7, 7, 6.[/tex]
So, the mean is:
[tex]\bar x = \frac{6+ 8+ 5+ 9+ 4+ 5+ 8+ 7+ 7+ 6}{10}[/tex]
[tex]\bar x = \frac{65}{10}[/tex]
[tex]\bar x = 6.5}[/tex]
So, the average distance is 6.5
a rectangular tree lot must have a perimeter of 100 yards and an area of at least 500 square yards. Describe the possible lengths of the tree lot
Answer:
36.18 yd and 13.82yd
Step-by-step explanation:
Area of the rectangular tree = Length * Width
A = LW
perimeter of the rectangular tree = 2(L+W)
Given
Area = 500 square yards and
perimeter = 100yards, then;
100 = 2L+2W
50 = L+W .... 1
500= LW ... 2
From 1, W = 50-L
Substitute into 2;
LW =500
L(50-L) = 500
50L-L² = 500
L²-50L + 500 = 0
Factorize
L = 50±√50²-4(500)/2
L = 50±√2500-2000/2
L = 50±√500/2
L = 50±22.36/2
L = 72.36/2 and 27.64/2
L = 36.18 and 13.82
Hence the possible lengths of the tree lot are 36.18 yd and 13.82yd

A building casts a shadow that is 50 feet in length. If the distance from the end of the shadow to the top of the building is 250 feet, what is the height of the building?
250 ft
50 ft
Answer: 244.95 feet
Step-by-step explanation:
This scenario forms the shape of a right angled triangle with the shadow length being the triangle's length and the distance between the end of the shadow to the top of the building being the hypotenuse.
Use Pythagorean theorem:
c² = a² + b²
250² = 50² + b²
62,500 = 2,500 + b²
b²= 62,500 - 2,500
b² = 60,000
b = √60,000
b= 244.95 feet

Write an inequality to match this statement: -7 is located to the right of -10. **Hint** You need to use shift and the comma button or the period button to make the greater than or less than sign. *
please tell the answer and explain how to get it
Answer:
-7 > -10
Step-by-step explanation:
We just have to compare these two numbers. When you're comparing two negative numbers, the smaller number is the bigger one. Ex. -3 is bigger than -6, so we can say that -3 > -6 (-3 is greater than -6). This means that -7 is larger than -10, which allows you to say that -7 > -10.

For what value of a must LMNO be a parallelogram?
Answer:
a = 2.5
Step-by-step explanation:
For LMNO to be a parallelogram then opposite sides are congruent, so
ON = LM , that is
8b - 1 = 4b + 7 ( subtract 4b from both sides )
4b - 1 = 7 ( add 1 to both sides )
4b = 8 ( divide both sides by 4 )
b = 2
Then
MN = 2b + 1 = 2(2) + 1 = 4 + 1 = 5 , so
2a = 5 ( divide both sides by 2 )
a = 2.5
Thus
For LMNO to be a parallelogram , a = 2.5
The value of a that makes LMNO a parallelogram is 5/2.
What is a parallelogram?A parallelogram is a quadrilateral that has two pairs of parallel sides.
In a parallelogram, opposite sides and angles are equal.
The adjacent angles add up to 180 degrees.
We have,
In a parallelogram, the opposite sides are parallel and equal.
This means,
4b + 7 = 8b - 1
7 + 1 = 8b - 4b
8 = 4b
b = 2
Now,
2a = 2b + 1
2a = 2 x 2 + 1
2a = 4 + 1
2a = 5
a = 5/2
Thus,
The value of a is 5/2.

A self-serve frozen yogurt store sells servings up to 12 ounces. It charges $0.50 per ounce for a serving between 0 and 8 ounces, and $4 for any serving greater than 8 ounces and up to 12 ounces.
Build the function that models the relationship between the price p(w) and of the weight w of a serving of yogurt.
Answer:
p(w) - - - - - - p = 0.5w ; for 0 < w ≤ 8
p(w) - - - - - - p = 4 ; for w < 8 and w ≤ 12
Step-by-step explanation:
Price, p of weight of a toughurt serving :
p(w) - - - - - - p = 0.5w ; for 0 < w ≤ 8
p(w) - - - - - - p = 4 ; for w < 8 and w ≤ 12
The function that models the relationship is:
p(w) = 0.50w for 0 < w ≤ 8
p(w) = 4w for 8 < w ≤ 12
The self-serve frozen yoghurt store charges:
$0.50 per serving for a serving between 0 and 8 ounces
$4 per serving for any serving greater than 8 ounces and up to 12 ounces.
Let the weight of servings be represented by w
Let the price as a function of the weight be p(w)
For a charge of $0.50 per serving:
p(w) = 0.50w, where 0 < w ≤ 8
For a charge of $4 per serving:
p(w) = 4w, where 8 < w ≤ 12
Therefore, the function that models the relationship is:
p(w) = 0.50w for 0 < w ≤ 8
p(w) = 4w for 8 < w ≤ 12
