Answer:
Median.
Step-by-step explanation:
The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. In simple terms, it may be thought of as the "middle" value of a data set. For example, in the data set {1, 3, 3, 6, 7, 8, 9}, the median is 6, the fourth number in the sample. The median is a commonly used measure of the properties of a data set in statistics and probability theory.

Given the function h(x)=-x^2-5x+14 determine the average rate of change of the function over the interval -9
Answer:
The average rate of change of the function over the interval is of 6.
Step-by-step explanation:
Average rate of change:
The average rate of change of a function h(x) over an interval [a,b] is given by:
[tex]A = \frac{h(b)-h(a)}{b-a}[/tex]
In this question:
Over the interval [-9,-2], so [tex]a = -9, b = -2, b - a = -2 -(-9) = 7[/tex]
The function is:
[tex]h(x) = -x^2 - 5x + 14[/tex]
[tex]h(-9) = -9^2 -5(-9) + 14 = -81 + 45 + 14 = -22[/tex]
[tex]h(-2) = -2^2 -5(-2) + 14 = -4 + 10 + 14 = 20[/tex]
Then
[tex]A = \frac{h(-2)-h(-9)}{7} = \frac{20-(-22)}{7} = \frac{42}{7} = 6[/tex]
The average rate of change of the function over the interval is of 6.

What does it mean when the result of solving a linear equation is x = 0?
a.
no solution
c.
the equation must be wrong
b.
zero is a valid solution
d.
like terms were not combined correctly
Please select the best answer from the choices provided
A
B
C
D
Answer:
a.no solution
Step-by-step explanation:
The solution x = 0 means that the value 0 satisfies the equation, so there is a solution. “No solution” means that there is no value, not even 0, which would satisfy the equation. ... If you substitute these values into the original equation, you'll see that they do not satisfy the equation

coat and a pair of boots are on sale
for 20% off.
The regular price of the coat is $250.
The regular price of the boots is $170.
Kayla wants to buy both the coat and
the boots. How much will she pay if she buys them during the sale?
Answer:
$336
Step-by-step explanation:
20% can be split into 2 10%
so to find 10% of a number U move the decimal point 1 place left
so 10% of 250 = 25, therefore 20% must equal
25 + 25 = 50. 20% of 250 is 50
and by doing the same this we find that 20% of 170 is 34
now minus the percentage from the original tO get the new price of both items
[tex]250 - 50 = 200[/tex]
[tex]170 - 34 = 136[/tex]
now add both 136 and 200 together to get the price she will pay for both on sale
[tex]200 + 136 = 336[/tex]

The school canteen charges Rs 42 for lunch and Rs 8 for milk for
each day. How much money do you spend in 5 days on these things? Write proper steps. State the property used.
Answer:
After 5 days buying lunch and milk at the canteen school, Rs 250 will be spent.
Step-by-step explanation:
Given that the school canteen charges Rs 42 for lunch and Rs 8 for milk for each day, to determine how much money do you spend in 5 days on these things, the following calculation must be performed, using the distributive property:
(42 + 8) x 5 = X
50 x 5 = X
250 = X
Therefore, after 5 days buying lunch and milk at the canteen school, Rs 250 will be spent.
A prism has a pentagonal base. The
area of the pentagon is 45 cm2, the
height of the prism is 13 cm. Find the
volume of the prism.
Answer:
585[tex]cm^{3}[/tex]
Step-by-step explanation:
45 x 13 = 585
Let me explain...
we don't know the length and the width but it is telling us that there is an area of 45 centimeters. Meaning the Length x Width is equal to the area. so there wasn't no need to solve for length and width.
So that's why we only had to multiply the 45 (Length x width) and the height which is 13.
Final Answer: 585[tex]cm^{3}[/tex]

Solve for X
1/5 X + 1/2 = 1
Answer:
X = 5/2
Step-by-step explanation:
I will assume that you meant (1/5)X + 1/2 = 1. The LCD is 10.
Multiplying both sides by 10, we get:
2X + 5 = 10, or 2X = 5, or X = 5/2

Primary Succession
Step-by-step explanation:
Ecological succession describes the ecological change in structure of a community of different species, or ecosystem. There are three main types of ecological succession. The first type is primary succession, followed by secondary succession, and then cyclic succession. Primary succession is the first formation of plants without soils with the presence of magma and water. Secondary succession takes place with the destruction of primary succession by fire, for example. Cyclic succession is the change of the ecosystem on a cyclic basis depending on time of the year.
Answer:
The answer would be secondary succession :)
