In order to solve it you must make each component negative. Multiply them by negative one!

M < 2

Now which numbers would satisfy it? M is less than two... so, m could be one, or any negative number, yeah?

Multiply by negative one. - M and -2 are what you have. If it were one... negative one is less than negative two. Turns out M is less than two.

M < 6

M is less than six. It could be 1, 2, 3, 4, or 5.

-M and -6

Is negative 3 less than -6? All of the numbers are! So, m is actually less than 6

How do i do this some one please explain

Well since we already have our unit per mile.

We know that 1 mile = $3.50

And that the tow company towed the car 12 miles.

So we would have to multiply 12 by $3.50

soo..

12 x $3.50 = $42.00

So your answer is D. $42.00

60$. These are my equations :
600 * 0.2 = 120 ; 600 - 120 = 480
Then...
600 * 0.1 = 60 ; 600 - 60 = 540
Which then became....
540 - 480 = 60

Basile [38]

This question is incomplete, the complete question is;

Let X denote the time in minutes (rounded to the nearest half minute) for a blood sample to be taken. The probability mass function for X is:

x 0 0.5 1 1.5 2 2.5

f(x) 0.1 0.2 0.3 0.2 0.1 0.1

determine;

a) P( X < 2.5 )

B) P( 0.75 < X ≤ 1.5 )

Answer:

a) P( X < 2.5 ) = 0.9

b) P( 0.75 < X ≤ 1.5 ) = 0.5

Step-by-step explanation:

Given the data in the question;

The probability mass function for X is:

x 0 0.5 1 1.5 2 2.5

f(x) 0.1 0.2 0.3 0.2 0.1 0.1

a) P( X < 2.5 )

P( X < 2.5 ) = p[ x = 0 ] + p[ x = 0.5 ] + p[ x = 1 ] + p[ x = 1.5 ] + p[ x = 2 ]

P( X < 2.5 ) = 0.1 + 0.2 + 0.3 + 0.2 + 0.1

P( X < 2.5 ) = 0.9

b) P( 0.75 < X ≤ 1.5 )

P( 0.75 < X ≤ 1.5 ) = p[ x = 1 ] + p[ x = 1.5 ]

P( 0.75 < X ≤ 1.5 ) = 0.3 + 0.2

P( 0.75 < X ≤ 1.5 ) = 0.5

Answer:

Mia can spend no more than $55 at the mall. She buys a jacket for $23. Necklaces are on sale for $8. Find the amount of necklaces Mia can buy. Write and solve an inequality.

First, make the equation. She can't waste no more than(≥ or =) $55. And she already used $23.

55= 23+8(n)

n= number of necklaces she can buy.

Now, subtract 23 to both sides.

55= 23+8(n)

-23 -23

32= 8(n)

Then, divide by 8 to both sides to find how many necklaces she can buy.

32= 8(n)

8 8

4=n So, she can buy 4 necklaces.

A bag of marbles contains 3 red, 5 blue and 2 yellow marbles. What is the probability of choosing a blue marble and then choosing a red marble without replacement. Simplify the fraction.

First, add up the whole amount of marbles.

3+5+2= 10

This is very simple, to find the probability, just put...

number of blue marbles

total number of marbles

This gives you, 5/10 and simplified into 1/2.

For the red marble, do the same thing.

number of red marbles

total number of marbles

This gives you, 3/10 and it can't be simplified.

A football team loses 5 2/3 yards on the first play. On the next play, they gain 2 3/4 yards. What is the overall increases or decreases in yards?

For this word problem, add 2 3/4 yards to 5 2/3 yards to find the overall decrease or increase in yards.

Solve the whole number parts..

5-2= 3

Solving the fractions part...

2 - 3 = 8 - 9 = - 1

3 4 12 12 12

3- 1/12= 2 11/12

So, it was a 2 11/12 decrease.
