Let us say that "a number" is x. If you were to do this, then the product of 7 and a number, x would be 7x.

You would consider it as "7n=x" as n is the undefined number and since it is an equation, it must have an equal sign, so x is the product.

Hiroshi found that 3/5 of his class prefers vanilla ice cream, 26% prefers chocolate ice cream, and 0.14 prefers strawberry ice
andre [41]

Answer:

The kind of ice cream the least number of students prefer is Strawberry ice cream.

Step-by-step explanation:

We convert all given values to decimal

Hiroshi found that:

a) For vanilla ice cream

3/5 of his class prefers vanilla ice cream

3/5 to decimal = 0.6

b) For Chocolate ice cream

26% prefers chocolate ice cream

26% to decimal = 0.26

c) For strawberry ice cream

0.14 prefers strawberry ice cream

0.14 = 0.14

Arranging the numbers in order from least to greatest, we have :

0.14, 0.26 , 0.6

The kind of ice cream the least number of students prefer is Strawberry ice cream.

What are integers and how are they used to represent real-world quantities?
Varvara68 [4.7K]
Integers are every number that is negative, positive, or zero

integers DO NOT include anything more, so no decimals

examples would be

how many grains of sand on the beach?
how many jelly beans in the jar? (assuming none of them are cut in half)
how many times did you call someone? (cant do it half a time)
how many people were born today? (don't get into people not counting as 1)
how many people answered this question on brainly?

just that kind of stuff

Si lanzas una moneda justa 4 veces, ¿cuál es la probilidad
Alexeev081 [22]

Answer:

The probability of getting exactly 2 soles is 0.375.

Step-by-step explanation:

The question is:

If you toss a fair coin 4 times, what's the probability that you get exactly 2 soles?

Solution:

A fair coin has two parts.

On tossing a coin once there is 50-50 odds of both the sides.

So, the probability of one side is, <em>p</em> = 0.50.

It is provided that a fair coin is tossed <em>n</em> = 4 times.

The event of any of the sides showing up after the toss are independent of each other.

The random variable <em>X</em> defined as soles, follows a Binomial distribution with parameters <em>n</em> = 4 and <em>p</em> = 0.50.

The probability mass function of <em>X</em> is:

P(X=x)={4\choose x}\ (0.50)^{x}\ (1-0.50)^{4-x};\ x=0,1,2,3,4

Compute the probability of getting exactly 2 soles as follows:

P(X=2)={4\choose 2}\ (0.50)^{2}\ (1-0.50)^{4-2}

                =6\times 0.25\times 0.25\\\\=0.375

Thus, the probability of getting exactly 2 soles is 0.375.

Segment PN as a radius is from the middle point of the circle to the outside. Think of cutting a pizza into pieces you will only begin slicing from the middle. So the radius is from the middle to the outside. Whereas the diameter is the as if you cut the pizza in half. Therefore the diameter is double the radius
