Y=-10x+50 x=9, y=??

Mathematics
1 answer:
Fittoniya [83]3 years ago
7 0

Answer:

-40

Step-by-step explanation:

Plug in 9 for x.

Use Order of operations

-10(9) = -90

-90 + 50 is the same thing as saying 50 - 90

we can simplify by splitting the -90 in to a -40 and a -50

the new equation could be 50 - 50 -40.

50 - 50 = 0

0-40 = -40

M and N are independent events. P(M | N) = 0.71. Find P(M)
mash [69]

Since M and N are independent events, P(M)=P(M|N)=0.71

Step-by-step explanation:

Two events A and B are said to be independent when the probability of A happening does not depend on whether B has happened or not.

In other word, this condition can be rewrite as follows:

P(A|B)=P(A)

where

P(A|B) is the probability of A happening  given that B has happened

P(A) is the probability of A happening

In this problem, we have:

- M and N are independent events: so M does not depend on whether N occurs or not

Therefore,

P(M)=P(M|N)

- Also, we know that

P(M|N)=0.71

Therefore, it follows that

P(M)=0.71

BamBam's father gives him a weekly allowance of $2500. If he spends 380 per day, how much money will he be left after 16 days? ​
vichka [17]
16 days is a part of 3 weeks, so $2500 x 3 = $7500. if he spends $380 per day for 16 days, that equals $6080. so subtract $6080 from $7500 and you get $1420 (how much he has left)

Help, please?<br> Choose the best graph that represents the linear equation:<br> y + 3 = 0
Nookie1986 [14]

Answer:

The answer is group C

Step-by-step explanation:

The graph of group C depicts a typical and perfect presentation of the linear equation y+3=0

Simplifying the above equation thus:

y + 3 = 0

Make y subject of formula by subtracting 3 from both sides. Thus,

y + 3 - 3 = 0 - 3

y =  -  3

Therefore, we draw a straight line across -3 on y axis. Hence, group C linear graph.
