Answer:

Step-by-step explanation:

The mean, or average, of a data set can be found by adding all the numbers together, then dividing by the number of values in the set.

1. Add the numbers

The data set is: 1,2,3,4,5

Add all these numbers together

1+2+3+4+5=15

2. Divide by the number of values

The data set is: 1,2,3,4,5

There are 5 values in the set.

Divide 15 by 5.

15/5=3

The mean, or average of the data set is 3.

Find two consecutive integers such that four times the larger exceeds three times the smaller by 23

Bad White [126]

CONSECUTIVE NUMBERS; x, x+1
(x+1)4=3(x)+23
4x+4=3x+23
4x-3x=23-4
x=19
x+1=20
THEREFORE the consecutive numbers are 19&20

Read this description of the life cycle of a mushroom. 1. A mushroom begins to grow underground as a single-celled "spore.” 2. T

Dahasolnce [82]

The correct answer is C. The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground.

Explanation:

Two key features of living organisms are energy processing and response to stimuli. These two features imply organisms require nutrients, which can be taken from the environment or created through a process such as photosynthesis and they sense their surroundings and respond to it.

Moreover, these two features are exemplified by mushroom (fungi) in the sentence "The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground" because the first section shows the developing mushroom takes nutrients from the soil or its environment and this is essential for growing and survival. Also, the second section of the sentence shows the developing mushroom can sense its environment and respond by developing only in appropriate conditions.

A boat's value over time is given as the function f(x) and graphed below. Use A(x) = 400(b)x + 0 as the parent function. Which g

Lelu [443]

Answer:

Last Graph (4th one)

Step-by-step explanation:

The equation given is $A(x)=400*b^x + 0\\A(x) = 400b^x$

Since we want increase of 25%, the value of b would be 1.25, so we have:

$A(x)=400(1.25)^x$

The graph should be increasing so we can immediately eliminate 2nd and 3rd graphs since they are clearly decreasing. We now have to choose between 1st graph and 4th graph.

1st graph:

Let's take the point (-20,30)

$A(x)=400(1.25)^{-20}\\A(x)=4.65$

2nd graph:

Let's take the point (-20,4.5)

$A(x)=400(1.25)^{-20}\\A(x)=4.65$

hence, this makes sense. So the correct graph is 4th one.
