Which of the following could not be a value of probability<br><br>HELP

Dafna11 [192]

To find out how many quarts there are in 40 gallons, we simply need to know how many quarts there are in one gallon. As the name implies, there are 4 quarts in one gallon, so we simply need to multiply 4 * 40 to find the amount of quarts in 40 gallons.

4 * 40 = 160

There are 160 quarts in 40 gallons.
Hope that helped! =)

The Slope of the Line:

Paladinen [302]

Answer:

3/-1

Step-by-step explanation:

the equation for slope is y2-y1/x2-x1

I chose the two points (4,2) and (0,-2) because that's where the line meets up

then I put them in the equation getting 4--2/0-2

simplifying getting you 6/-2

you can simplify more giving you 3/-1

A particular metal alloy a has 20% iron and another alloy b contains 60% iron. how many kilograms of each alloy should be combin

Veronika [31]

Let t and s represent the masses of 20% and 60% alloys respectively.

t+s=80, s=80-t

(0.2t+0.6s)/80=0.52 multiply both sides by 80

0.2t+0.6s=41.6, now using s=80-t in this equation gives us:

0.2t+0.6(80-t)=41.6 perform indicated multiplication on left side

0.2t+48-0.6t=41.6 combine like terms on left side

-0.4t+48=41.6 subtract 48 from both sides

-0.4t=-6.4 divide both sides by -0.4

t=16, since s=80-t

s=64

So 16kg of 20% alloy is mixed with 64kg of 60% allow to make 80kg of a 52% alloy.

Special precision bolts are made by another machine. These are for jobs that require more exact measurements. The bolts must be

zalisa [80]

The absolute value of a number $x$ is the positive version of that number. So, if $x$ is positive, its absolute value is $x$ itself. If $x$ is negative, its absolute value is $-x$ , so that it will be positive again.

So, if the absolute value of a number is smaller than a certain quantity, i.e. $|x|$ it means that the positive version of $x$ is less than $a$ .

So, if $x$ is positive, the inequality becomes $x$ . If $x$ is negative, the inequality becomes $-x-a$ .

So, as a compound inequality, we have

$|x|$

So, in your case, we have

$|x-8|$

Add 8 to all sides in this inequality:

$8-0.01 < x < 8+0.01 \iff 7.79 < x$

So, on a number line, you must higlight all numbers between 7.79 and 8.01, endpoints excluded.

Conceptually, this means that the bolt measurement should be exactly 8mm, but you can accept bolts that are 0.01 millimeters shorter of larger.

Evaluate 38+16 * 12÷2-(30 * 2)

Dvinal [7]

Answer

The answer is 8040

Step-by-step explanation:

It might be wrong, but here take it this way with Pemdas.

P= Parenthesis (30*2) and what's in there is multiplication correct? So, 30 times 2 is 60. Then, E is exponents. There's none there. So we skip to multiplication. 16 times 12 is what? 192. Next is division. So 192 divided by 2. That's 96. So, Then it'd be 38+96(60.) 38+96= 134. 134(60) That being said. That would equal = 8040 using Multiplication, 194 using addition. 74 using subtraction. And 2.2_ using division.
