Answer:

mean=sum of all the data number of the data

= 2+3+4+5+0+1+3+3+4+3/10

= 28/10

= 2.8

I hope this helps

Answer:

its 2•8

u add all together then divide it number of times e.g 2+3+4+5+0+1+3+3+4+3=28

so 28/10= 2•8

Consider the right angle shown below

atroni [7]

Answer:

Part A:

given that cos β = 3/5

that means the base line is 3 and the hypotenuse is 5

Note that, The base line 3 is adjacent to β and opposite to α.

Sin α = opposite / adjacent

sin α = 3 /5

Part B:

α and β are complementary angles

Let f(x) = 2x + 5 and g(x) = x^2 - 3x + 2

denis-greek [22]

Answer:

The answer to your question is below

Step-by-step explanation:

f(x) = 2x + 5

To solve letter a, just multiply each term of f(x) by 3 and subtract 2.

a) 3f(x) - 2 = 3(2x + 5) - 2

= 6x + 15 - 2

= 6x + 13

To f(x) subtract twice g(x)

b) f(x) - 2g(x) = 2x + 5 - 2(x² - 3x + 2)

= 2x + 5 - 2x² + 6x - 4

= -2x² + 8x + 1

Multiply 5 by each term of f(x) and divide it by g(x)

c) $\frac{5f(x)}{g(x)} = \frac{5(2x + 5)}{x^{2} - 3x + 2}$

= $\frac{10x + 25}{x^{2}-3x + 2}$

The graph of y = h (x) is a line segment joining the points (-7,-5) and (-1,-2) drag the endpoints of the segment below to graph

sertanlavr [38]

Answer: Ok, i cant drag the endpoints of the segment, but i can tell you how to do it.

First, we know that h(x) joins the points (1, -5) and (9, 1), then h(x) is a line:

h(x) = s*x + b

First, for a line that goes through the points (x1, y1) and (x2, y2), the slope will be:

s = (y2 -y1)/(x2 - x1)

Then in this case, the slope is:

s = (1 - (-5))/(9 - 1) = 0.75

Then we have

h(x) = 0.75*x + b

now, the value of b can be found as:

h(1) = -5 = 0.75*1 - b

b = - 5 - 0.75 = -5.75.

Then our equation is:

h(x) = 0.75*x - 5.75

Now, i gues you want to find the graph of:

y = h(-x)

Then our new function is:

g(x) = h(-x) = -0.75*x - 5.75.

Now to find the points, we evaluate this function in the same values of x as before.

g(1) = -0.75*1 - 5,75 = -6,5

the point is (1, -6.5)

the second point is when x = 9.

g(9) = -0.75*9 - 5.75 = -12.5

The second point is (9, -12.5)

Every hour, a machine makes the same number of tennis racquets. If on the 3rd hour of running, the machine has made 240 racquets

Vika [28.1K]

Answer:

80 racquets per hour.

Step-by-step explanation:

Divide 240 by 3, and you'll get 80. To double check, divide 400 by 5 and you'll still get 80. Hope that helps.
