Michael uses a uniform probability model for an experiment using a deck of 45 cards. There are 15 blue card, 15 red cards, and 1

vampirchik [111]

Answer:

P = 2/3

Step-by-step explanation:

45 cards in all

15 blue

15 red

15 green

To figure out the probability of red and blue together, add red and blue.

15 + 15 = 30

Since the total is 45, this is how many 30 will be out of.

30 out of 45 = 30/45

Simplify 30/45 by dividing each side by 15

30 ÷ 15 = 2

45 ÷ 15 = 3

30/45 = 2/3

Find the 75th term of the following6, 10, 14, 18,

enot [183]

Given the sequence:

6, 10, 14, 18,...

We will find the 75th term

The given sequence is an arithmetic sequence

Because there is a constant common differnce

d = 18 - 14 = 14 - 10 = 10 - 6 = 4

The first term = a = 6

The general formula of the arithmetic sequence is as follows:

$a_n=a+d(n-1)$

Where: n is the nth term

To find the 75th term, substitute with n = 75 and a = 6, d = 4

$a_{75}=6+4\cdot(75-1)=302$

So, the answer will be the 75th term = 302

Show how you can scaffold a grade 2 class to understand the following mathematics topic it’s concepts and application. 1.1.1 nam

stich3 [128]

The best way to scaffold a grade 2 class to understand the topics such as unitary fractions, fractions in diagrammatic form, write fractions as 1 half is by first explaining the definition then real life application including physical representation.

What is fraction?

A fraction is a portion of a whole or, more roughly, any number of equal pieces. The word fraction comes from the Latin word fractus, which meaning "broken." When expressed in common English, a fraction, such as one-half, eight-fifths, or three-quarters, specifies the number of components of a specific size. A common, vulgar, or simple fraction is one with a non-zero denominator that is displayed below (or after) the line on which the numerator is displayed. Examples of these fractions include 1/2 and 14/3. The uncommon fractions that use numerators and denominators are difficult fractions, compound fractions, and mixed numeral fractions.

Definition or explanation of the topics given in the question:

Unitary fractions or Unit fractions: A fraction with the number one in the numerator is known as a unit fraction in mathematics. Of all the equally sized portions of the whole, it symbolizes one shaded part. "Unit" refers to one.

For instance, 1/4 is the numerical representation of a pizza that has been divided into 4 equal portions, each of which is being consumed by one individual similarly if it got divided between 2 people it is represented as 1/2.

Recognize fractions in diagrammatic form: This could be done by showing the diagrams which contain boxes of two different colors which represents the numerator and denominator.

Write fractions as 1 half: The 1 half fractions are the fractions in which the denominator is twice the the numerator. That is any fraction in the form n\2n where, n = 1, 2, 3, 4.... is the 1 half fraction.

Answer:

a. Function 1

b. Function 3

c. Function 2, Function 3 and Function 4

Step-by-step explanation:

✔️Function 1:

y-intercept = -3 (the point where the line cuts across the y-axis)

Slope, using the two points (0, -3) and (1, 2):

$\frac{y_2 - y_1}{x_2 -x_1} = \frac{2 -(-3)}{1 - 0} = \frac{5}{1} = 5$

Slope = 5

✔️Function 2:

y-intercept = -1 (the value of y when x = 0)

Slope, using the two points (0, -1) and (1, -4):

$\frac{y_2 - y_1}{x_2 -x_1} = \frac{-4 -(-1)}{1 - 0} = \frac{-3}{1} = -3$

Slope = -3

✔️Function 3: y = 2x + 5

y-intercept (b) = 5

Slope (m) = 2

✔️Function 4:

y-intercept = 2

Slope = -1

Thus, the following conclusions can be made:

a. The function's graph that is steepest is the function whose absolute value of its slope is greater. Therefore Function 1 is the steepest with slope of 5

b. Function 3 has a y-intercept of 5, which is the farthest from 0.

c. Function 2, Function 3, and Function 4 all have y-intercept that is greater than -2.

-1, 5, and 2 are all greater than -2.
