30, 45, 40, 37, 37, 40, 42, 38, 37, 42, 43, 38 Make a line plot of the data set. Find the median of the data set.

1 answer:

7 0

To find the median order your numbers from least to greatest so

30 37 37 37 38 38 40 40 42 42 43 45

now just cross out the end numbers until you get the number in the middle which is 38 and 40.

what you'd do if there is 2 medians you add them together and divide by 2 so 40+38 equals 78 then divided by 2 is 39.

answer is 39

after 3 weeks a corn plant is 2 ft tall after 9 weeks the plant is 8 ft tall write an equation that represents the height Y in f

spayn [35]

Answer:

The equation would be y = x - 1

Step-by-step explanation:

In order to find the equation of the line, we first can express the two sets of data as an ordered pair. The two ordered pairs would be (3, 2) and (9, 8). Now that we have these, we can use the slope formula to find the slope.

m (slope) = (y2 - y1)/(x2 - x1)

m = (8 - 2)/(9 - 3)

m = 6/6

m = 1

Now that we have the slope, we can use either point and point slope form to get the equation.

y - y1 = m(x - x1)

y - 2 = 1(x - 3)

y - 2 = x - 3

y = x - 1

Jan and Wayne went to the store to buy some groceries. Jan bought 2 cans of corn beef hash and 3 cans of creamed chipped beef fo

yulyashka [42]

Answer:

The system of equations that models the problem is:

$\left \{ {{2*H+3*C=4.95} \atop {3*H+2*C=5.45}} \right.$

Step-by-step explanation:

A system of equations is a set of two or more equations with several unknowns in which we want to find a common solution. So, a system of linear equations is a set of (linear) equations that have more than one unknown that appear in several of the equations. The equations relate these variables or unknowns to each other.

In this case, the unknown variables are:

H: price of a can of corn beef hash
C: price of a can of creamed chipped beef

Knowing the unit price of a product, the price of a certain quantity of that product is calculated by multiplying that quantity by the unit price. So the price for 2 cans of ground beef hash can be calculated as 2 * H and the price for 3 cans of ground beef with cream can be calculated as 3 * C. Jan paid $ 4.95 for those amounts from both cans. This means that the sum of the can prices must be $ 4.95. So: 2*H + 3*C= 4.95 Equation (A)

Thinking similarly, if Wayne bought 3 cans of corn beef hash and 2 cans of creamed chipped beef for $5.45, Wayne's buy can be expressed by the equation:

3*H + 2*C= 5.45 Equation (B)

Finally, the system of equations that models the problem is:

$\left \{ {{2*H+3*C=4.95} \atop {3*H+2*C=5.45}} \right.$

(b) What is 0.36 (Six is Repeating) expressed as a fraction in simplest form?

Ugo [173]

A = 0.366666 ... = 0.3(6)

10a = 3.(6)
100 a = 36.(6)
100a - 10a = 36.(6) - 3.(6)
90a = 33
a=33/90=11/30
oh wait lol i didnt notice it was from 2017
