A set of equations is given below:

ipn [44]

The correct answer is 'Equation F can be written as 2d + 1 = 3d + 7'. In order to find the answer to a system of equations, the two equations must be set equal to each other. For instance, if we had the equations x = y + 1 and x = 3y - 1, we would set the two equations equal to one another to find the answer.

x = y + 1
x = 3y - 1
y + 1 = 3y - 1
1 = 2y - 1
2 = 2y
1 = y

x = y + 1
x = 1 + 1
x = 2

We can use this to solve the set of equations above.

2d + 1 = 3d + 7
1 = d + 7
-6 = d

c = 2d + 1
c = 2(-6) + 1
c = -12 + 1
c = -11

Hope this helps!

Calculate the mean deviation by median (by using the mid-point(x) of leaf weights. b) A fair die is rolled. Find the probability

SVETLANKA909090 [29]

Answer:

hello attached below is the required table that is missing and the completed table as well

A) mean deviation = 0.1645

B) 2/3

Step-by-step explanation:

From the table we calculated the midpoint value (x) and c.f

N = 27

median class = 2.35 to 2.45

median = l + [ (N/2) - cf / F ] * H

= 2.35 + [ (13.5 - 13) / 6 ] *0.1 = 2.3583

hence mean deviation by median

= summation of fi |xi -M| / summation of fi

= 4.4417 / 27 = 0.1645

B ) probability of getting an odd number or prime number or both

the probability of an odd number = 1/2

also the probability of an even number = 1/2

while the probability of getting neither of them = 1/3

hence the probability of getting odd or prime or both

= 1/2 + 1/2 - 1/3 = 2/3

How many kilometers are there in 9000000cm

tekilochka [14]

QUESTION:- How many kilometers are there in 9000000cm.

ANSWER:-

$1cm = {10}^{ - 5} km \\ 9000000cm =9000000 \times {10}^{ - 5} km \\ 9 \times {10}^{6} cm = 9 \times {10}^{6} \times {10}^{ - 5} \\ 9 \times {10}^{6} cm = 9 \times {10}^{6 - 5} \\ 9 \times {10}^{6} cm = 90km$
