If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalen
alexandr1967 [171]

The new equation after the expression equivalent to x from the first equation is substituted into the second equation is: 2(-4y-9)+5y=-6

Step-by-step explanation:

We will solve the initial steps for substitution method for finding the correct answer

Given equations are:

x+4y = -9\ \  \ \ Eqn1\\2x+5y=-6\ \ \ Eqn2

From equation one

x+4y = -9\\x+4y-4y = -9-4y\\x = -4y-9

Putting x = -4y-9 in equation 2

2(-4y-9)+5y=-6

Hence,

The new equation after the expression equivalent to x from the first equation is substituted into the second equation is: 2(-4y-9)+5y=-6

The route used by a certain motorist in commuting to workcontains two intersections with traffic signals. The probabilitythat he
zavuch27 [327]

Answer:

a) 0.2

b) 0.2

c) 0.5

Step-by-step explanation:

Let S be the event "the car stops at the signal.

In the attached figure you can see a tree describing all possible scenarios.

For the first question the red path describes stopping at the first light but not stopping at the second. We can determine the probability of this path happening by multiplying the probabilities on the branches of the tree, thus

P(a)=0.4\times0.5=0.2

For the second one the blue path describes the situation

P(b)=0.4\times 0.5=0.2

For the las situation the sum of the two green path will give us the answer

P(c)=0.6\times 0.5 + 0.4\times 0.5=0.3+0.2=0.5

What is the MAD of this numbers?
Stella [2.4K]
We know that
The MAD is <span>the mean absolute deviation of the data

step 1
</span><span>To find the mean absolute deviation of the data, start by finding the mean of the data set.
</span><span>Find the sum of the data values, and divide the sum by the number of data values
</span>sum of the data values=[130+150+190+100+175+120+165+140+180+190]
sum of the data values=1540
number of data=10
Mean=1540/10-----> 154

step 2
<span>Find the absolute value of the difference between each data value and the mean: |data value – mean|.
</span> |130 – 154|=24
 |150 – 154|=4
 |190 – 154|=44
 |100 – 154|=54
 |175 – 154|=21
 |120 – 154|=34
 |165 – 154|=11
 |140 – 154|=14
 |180 – 154|=26
 |190 – 154|=44

step 3
<span>Find the sum of the absolute values of the differences.
</span>=[24+4+44+54+21+34+11+14+26+44]------> 276

step 4
<span>Divide the sum of the absolute values of the differences by the number of data values.
</span>276/10-----> 27.6

the answer is
27.6

They are 6 apart, right?

How far is -4 to 4 vertically? 8.

__________________________________________________________

6^2 + 8^2 = c^2

36 + 64 = c^2

c = 100 = 10
