The probability that a college student will get to work in 30 mins or less is 0.4 or 40%.

What does uniformly distributed probability mean?

Uniform distribution refers to a type of probability distribution in which all outcomes are equally likely to occur.

According to the given question:

Since the time is uniformly distributed, every possible travel time has the same likelihood of occurring.

Lower boundary (L) = 20 minutes

Upper boundary (U) = 45 minutes

The probability that a student finishes her trip in 30 minutes or less is:

P (t ≤ 30) = (30 - L)/(U - L)

              = (30 - 20)/(45 - 20)

              = 10/25

              = 0.4 or 40%

The probability that she will get to work in 30 mins or less is 0.4 or 40%

Which transformation was performed on PQRS to form P'QʻR'S'? (1 point)
REY [17]

Given:

A transformation was performed on PQRS to form P'QʻR'S'.

To find:

The transformation.

Solution:

The given graph shows two similar polygons. It means, dilation was performed.

From the given graph it is clear that,

PS=2 units

P'S'=1 units

Now,

\text{Scale factor}=\dfrac{P'S'}{PS}

\text{Scale factor}=\dfrac{1}{2}

A dilation factor of \dfrac{1}{2} was performed on PQRS to form P'QʻR'S'.

Therefore, the correct option is (3).

In a line of students, Jenna is number 8.The teacher says that a rule for a number pattern is add 4. The first student inline sa
Virty [35]

Answer:

Formula for nth term in Arithmetic sequences is:

a_n =a+(n-1)d

where a is the first term, d is the common difference and n is the number of terms.

As per the statement:

The rule for the pattern is add 4.

As the first term in line says the first term i,e 7

a= 7

common difference(d)= 7

As the Jenna number is 8th in line.

Series we get;

7, 11, .........a_8

We have to find the 8th term.

n = 8, a = 7 and d = 4

Using above formula:

a_8 = 7+(8-1)4 = 7+7 \cdot 4 = 7 +28 = 35

Therefore, 35 number should Jenna say.

Write an expression to represent: "the difference of 8 squared and a number"
Gnom [1K]

Answer:

The expression is (64 - x).

Step-by-step explanation:

The statement is:

"the difference of 8 squared and a number"

Let the number be denoted by <em>x</em>.

The value of 8 squared is:

8^{2}=8\times 8\\

   =64

Then the expression for the provided statement is:

(64 - x)

Thus, the expression is (64 - x).
