Answer:

A) 66cm³

Step-by-step explanation:

Using the Pythagorean Theorem, the base of the triangle is 4.  The area of a triangle is 1/2 base times height.  Then you multiply times 11 to get the volume.

1/2(3)(4)(11)=66

Answer:

33feet

Step-by-step explanation:

If the base of the doghouse is 6 feet and the height is 5 feet, we can write;

6 feet base = 5 feet height

To get the length of the base if the height is 27.5feet

x feet base = 27.5 feet high

Divide both expressions

6/x = 5/27.5

5x = 6 * 27.5

5x = 165

x = 165/5

x = 33ft

Hence the length of its base will be 33feet

(2,-2)

Answer:

Yes, there should be a solution.

Step-by-step explanation:

y = -2x + 2; slope is -2.

It is graphed at (0, 2) (1, 0)

You could write this as y = -2x

y = 2x - 6; slope is 2.

It is graphed at (0, -6) (3, 0)

You could write this as y = 2x - 6

I did as much as I could, hope this helps. Good luck hun! I don't expect brainliest.

Answer:

Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.

Answer:

uh 1/3???

Step-by-step explanation:

The data in the table is plotted by using a histogram as shown in the diagram attached below.

A histogram can be defined as a type of chart that is used to graphically represent a group of data points (statistical information) into user-specified ranges through the use of rectangles.

Generally, the area of each rectangle is directly proportional to the data frequency and its width is equal to the class interval.

Given the following data:

Length of time (t)                                  Frequency.

The vertical axis (y-axis) of the histogram would be used to represent the frequency density while the horizontal axis (y-axis) of the histogram would be used to represent the lengths of time spent (in hours) spent by the children in watching Tv last week as illustrated in the diagram below.

Answer:

f(5) = -11

Step-by-step explanation:

Given that,

f(x) = 4-3x ....(1)

We need to find the value of f(5).

Put x = 5 in equation (1)

f(5) = 4-3(5)

= 4-15

= -11

So, the value of f(5) is equal to -11.

Not a function.

Step-by-step explanation:

Do the vertical line test. If a line can go from top to bottom and touch the line twice, then it is not a function. A line like this would touch twice on this graph, so it is not a function.

Answer:

C. 3.8 years

Step-by-step explanation:

Exponential Growth

The natural growth of some magnitudes can be modeled by the equation:

[tex]P(t)=P_o(1+r)^t[/tex]

Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.

The actual population of deer in a forest is Po=800 individuals. It's been predicted the population will grow at a rate of 20% per year (r=0.2).

We have enough information to write the exponential model:

[tex]P(t)=800(1+0.2)^t[/tex]

[tex]P(t)=800(1.2)^t[/tex]

It's required to find the number of years required for the population of deers to double, that is, P = 2*Po = 1600. We need to solve for t:

[tex]800(1.2)^t=1600[/tex]

Dividing by 800:

[tex](1.2)^t=1600/800=2[/tex]

Taking logarithms:

[tex]t\log 1.2=\log 2[/tex]

Dividing by log 1.2:

[tex]t=\frac{\log 2}{ \log 1.2}[/tex]

Calculating:

t = 3.8 years
