How do you write 760 percent as a fraction or as a mixed number?

The expression used to represent the given phrase is given by x =5 and

y = 26 + 8x and value of the given expression when x =5 is equal to

y = 66.

As given in the question,

Given phrase is:

x equal 5

y equals 26 more than the product of 8 and a number x

Required expression to represent the given phrase is:

x = 5

y = 26 + 8x

Value of the expression y = 26 + 8x when x = 5 is given by :

y = 26 + 8( 5 )

⇒ y = 26 + 40

⇒ y = 66

Therefore, the required expression for the given phrase is x =5 and

y=26 +8x , the value of the expression y = 66 when x = 5.

Step-by-step explanation:

when a line is parallel the slope is the same for both

y=mx+b is slope intercept form where m is slope and b is intercept

we know the slope is 2/3 so to find b we just fill it in with coordinates

-2=2/3(-5)+b

-2=-10/3+b

The diameter of a dime tells us the circumference of a dime is approximately 299 times larger than human hair.

The diameter of an object is used to calculated the circumference or area of the object. This also helps us to know the width of a circular object.

In this problem, the diameter tells us about the length of the each quantity.

The diameter of a dime tells us how wide the coin is and the diameter if a hair tells us the width of the hair.

Comparing both values

Dime = 17.91mm

This equation x + (x + 1) + (x + 2) = negative 21 will be used.

Let the first Number is x.

We have to take 3 consecutive integers.

second Number is x+1

third Number is x+2.

Sum of these 3 consecutive integers is x+(x+1)+(x+2).

Sum of these 3 consecutive integers is given as negative21.

so we can write  x+(x+1)+(x+2)=negative 21.

by using above equation we can find the value of 3 numbers.

So the final equation will be x + (x + 1) + (x + 2) = negative 21.

The probability mass function (pmf) of X formally displays the likelihood of events where X=xk.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin.

The chance of both outcomes ("heads" and "tails") is equal because the coin is fair, "heads" is more likely than "tails," there are no other conceivable outcomes, and the likelihood of either outcome is half .

According to our question-

We can list the components of RX if X is a discrete random variable since RX is a countable set. In other words, RX=x1,x2,x3,... can be written.

Note that the random variable X here has the potential values x1, x2, x3
