Answer:
Mean = 59
Median = 58
Step-by-step explanation:
Given the data for a Javelin throw :
56, 58, 63, 57 61 meters
Reordering the data: 56, 57, 58, 61, 63
Mean, m = Σx / n
n = sample size = 5
m = (56 + 57 + 58 + 61 + 63) / 5
m = 295 / 5
m = 59
The median : 1/2 (n+1)th term
1/2(5 +1) the term
1/2(6) = 3rd term
Median value = 58

A ball is thrown into the air. The height h, in feet, of the ball after x seconds is given by the function h = −16(x − 2)2 + 72. What is the equation in standard form and the maximum height of the ball?
A. h(x) = −16x2 + 32x + 72; 72 ft
B. h(x) = −16x2 − 32x + 72; 32 ft
C. h(x) = −16x2 − 64x + 32; 32 ft
D. h(x) = −16x2 + 64x + 8; 72 ft
Answer:
Step-by-step explanation:
h = −16(x − 2)² + 72
= −16((x − 2)(x − 2)) + 72 expand the square (x - 2)² = (x - 2)(x - x)
= -16 ((x)(x) + (x)(-2) + (-2)(x) + (-2)(-2)) + 72
= -16 (x² + (-2x) + (-2x) + (4) ) + 72
= -16 (x² + (-4x) + (4) ) + 72
= -16 (x² - 4x + 4 ) + 72
= (-16)(x²) + (-16)(-4x) +(-16)(4) + 72
= -16x² + 64x - 64 + 72
= -16x² + 64x + 8 My guess is D ; 72 ???
I have no clue what the ; 72 means after the given answer. It must be a standard form thing I never learned.
The equation in standard form -16x² + 64x + 8 and the maximum height of the ball is 72 feet.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
The height h, in feet, of the ball after x seconds is given by the function
h = −16(x − 2)² + 72
Now, simplifying the above expression is
h = −16((x − 2)(x − 2)) + 72
h = -16 ((x)(x) + (x)(-2) + (-2)(x) + (-2)(-2)) + 72
h = -16 (x² + (-2x) + (-2x) + (4) ) + 72
h = -16 (x² + (-4x) + (4) ) + 72
h = -16 (x² - 4x + 4 ) + 72
h = (-16)(x²) + (-16)(-4x) +(-16)(4) + 72
h = -16x² + 64x - 64 + 72
h = -16x² + 64x + 8
and, the maximum height is 72 feet.

Answer:
-8n² - 8n + 3
Step-by-step explanation:
Combine like terms (terms with the same variables, as well as the same amount of that variable).
(4n⁴ - 8n + 4) - (8n² + 4n⁴ + 1)
First, distribute the negative sign to all terms within the second parenthesis:
4n⁴ - 8n + 4 - 8n² - 4n⁴ - 1
Combine like terms:
(4n⁴ - 4n⁴) - 8n² - 8n + (4 - 1)
-8n² - 8n + 3

In 2014, the population is of the United States was about 318,900,000 people. Choose the best approximation of the United States Population in 2014.
people
people
Answer:
people
Step-by-step explanation:
Given
US Population in 2014: About 318,900,000
Required
Approximate
From the given options, it's seen that the population of US is to be approximated to one significant digit and the result should be presented in standard form
So, the first step is to write out the population
318,900,000
As a general rule,
Category 1: Digit 0-4 are approximated to 0
Category 2: Digit 5-9 are approximated to 1
Since, we are approximating to one significant digit, only the first digit is needed, others are to be approximated.
The first digit is 3, meaning that approximation starts from the next digit which is 1
Approximating 318,900,000 will give 300,000,000 because "1" falls in category 1 as illustrated above.
The final step is to convert 300,000,000 to standard form.
There are 8 0s after 3.
Hence,
Conclusively, the approximation of 318,900,000 is people

The volume of a cylinder is 65 cubic centimeters. Which equation can be used to find h, the height of the cylinder?
A. h = 65/b, where B is the base area of the cylinder.
B. h = 65 - B, where B is the base area of the cylinder.
C. h = 65B, where B is the base area of the cylinder.
D. h = B/65, where B is the base area of the cylinder.
Answer:
Im so sorry for do this but can you help me click my profile pic the click the last question PLZZZZZZZ will give 50 brain
Step-by-step explanation:
The equation that can be used to find h, the height of the cylinder, is h = B/65. The correct option is D.
How to calculate the height?The formula for the volume of a cylinder is:
V = Bh
Where V is the volume, B is the base area, and h is the height of the cylinder. We are given that the volume of the cylinder is 65 cubic centimeters, so we can write:
65 = Bh
To solve for h, we can divide both sides of the equation by B:
h = 65/B
Therefore, the equation that can be used to find h, the height of the cylinder, is:
D. h = B/65, where B is the base area of the cylinder.

Katherine buys a tv with a normal price of $200 and she has a 25% off coupon. How much money did she save????
Given:
Normal price of a tv = $200
Coupon = 25% off
To find:
The money saved by Katherine.
Solution:
Katherine buys a tv with a normal price of $200 and she has a 25% off coupon. It means, the money saved by Katherine is 25% of normal price of tv, i.e., $200.
[tex]Saving=25\%\text{ of }200[/tex]
[tex]Saving=\dfrac{25}{100}\times 200[/tex]
[tex]Saving=25\times 2[/tex]
[tex]Saving=50[/tex]
Therefore, the money saved by Katherine is $50.
