Answer:

a. 1/13

b. 0.077

c. 7.7

Step-by-step explanation:

a. there are 4 of the 6 in a deck of cards so the probability of taking this cards from the deck of 52 cards is 4/52. Given you 1/13.

Probability is the chance of an event to occur from a total number of outcomes.

The answer in the reduced fraction is 1/13

The answer in decimal is 0.077

The answer as a percentage is 7.7 %

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Number of cards = 52

The number of cards randomly selected = 1

The number of cards that is 6 in a deck of 52 cards:

= 4

i.e

6 of spade

6 of diamond

6 of hearts

6 of club

Now,

The probability that a randomly selected card from a deck of

52 cards is 6:

= Number of cards that is 6 / Total number of cards

= 4 /52

The answer in the reduced fraction of 4/52 is 1/13

The answer in decimal:

= 4/52

= 0.0769

Rounding to its nearest thousandth.

= 0.077

The answer as a percent:

= 4/52 x 100

= 0.0769 x 100

= 7.69 %

Rounding to the nearest tenth.

= 7.7 %

Thus,

The answer in the reduced fraction is 1/13

The answer in decimal is 0.077

The answer as a percentage is 7.7 %

Answer:

  $2000

Step-by-step explanation:

The amount of interest is given by the formula ...

  I = Prt

where P is the principal invested, r is the annual rate, and t is the number of years. Here, we want to find P when I = 50, r = 0.05, and t = 1/2.

  50 = P(0.05)(1/2)

  P = 50/(0.05·1/2) = 2000

Alden started with $2000 in his account.

Answer:

b

Step-by-step explanation:

The slope of b is 5.5 whereas the slope for the other three graphs are 5, so B is different from the rest.

A. (4, 0.8), so by rise over run, the slope is 4/0.8=5.

B. (55, 10), so 55/10=5.5.

C. (20, 4), so 20/4=5.

D. (50, 10), so 50/10=5.

Since B is the only graph with a slope of 5.5 and the other graphs have a slope of 5, the answer is B.

First, what is an equation?

➳ A mathematical statement which shows that two algebraic expressions are equal is called and equation.

Or, LHS = RHS

Example:- 3x - 5 = x + 8

An equation is said to be a linear equation if it contains only one variable (literal) with highest power 1.

_______________________

Solving an equation:-

To solve the equation x + 5 = 7 means to find the value of an unknown algebraic quantity used in the equation.

Example:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ Rules for solving an equation by the substitution method:-

Rule ❶ 

If x = 2, the value of the expression 3x + 2 = 3 × 2 + 2 = 6 + 2 = 8

Rule ❷

If x = 0, the value of the expression 3x + 2 = 3 × 0 + 2 = 0 + 2 = 2

Rule ❸ 

If x = -2, the value of the expression 3x + 2 = 3 × -2 + 2 = -6 + 2 = -4

Now consider the algebraic expression 5x - 2y

This expression consists of variables x and y.

Now if :-

The process of finding the value of an algebraic expression by substituting the given value of its variable is called substitution.⠀⠀

Answer:

18

Step-by-step explanation:

Using the product rule

Given

y = f(x). g(x) , then

[tex]\frac{dy}{dx}[/tex] = f(x). g'(x) + g(x). f'(x)

Here

f(x) = [tex](2x+3)^{5}[/tex] ⇒ f'(x) = 5[tex](2x+3)^{4}[/tex] × [tex]\frac{d}{dx}[/tex] (2x + 3) , then

f'(x) = 10[tex](2x+3)^{4}[/tex]

g(x) = [tex](x+2)^{8}[/tex] ⇒ g'(x) = 8[tex](x+2)^{7}[/tex] × [tex]\frac{d}{dx}[/tex] (x + 2) , then

g'(x) = 8[tex](x+2)^{7}[/tex]

Thus

[tex]\frac{dy}{dx}[/tex] = [tex](2x+3)^{5}[/tex] . 8[tex](x+2)^{7}[/tex] + [tex](x+2)^{8}[/tex] . 10[tex](2x+3)^{4}[/tex] ← factor expression

    = [tex](2x+3)^{4}[/tex] [tex](x+2)^{7}[/tex] [ 8(2x + 3) + 10(x + 2)

    = [tex](2x+3)^{4}[/tex] [tex](x+2)^{7}[/tex] (16x + 24 + 10x + 20)

    = [tex](2x+3)^{4}[/tex] [tex](x+2)^{7}[/tex] (26x + 44)

Thus

[tex]\frac{dy}{dx}[/tex] ( x = - 1)

= [tex]1^{4}[/tex] × [tex]1^{7}[/tex] × 18

= 1 × 1 × 18

= 18

Answer:

14.4 centimeters

Step-by-step explanation:

The formula for circumference is: [tex]2\pi r[/tex]. In this case, the r (radius) is 2.3. Multiply it by 2 to get the diameter or 4.6. Then multiply 4.6 x [tex]\pi[/tex] (pi) to get 14.444. This rounded to the nearest tenth of a centimeter is 14.4.

Note:

I used 3.14 for [tex]\pi[/tex] (pi).

Answer:

(A) 5th day: 405 views

(B) inductive

Step-by-step explanation:

Each day the views get multiplied by 3.

Answer:

A. I would expect the video to have 405 views after day 5. There is a pattern of the number being multiplied by 3.

B. Deductive reasoning

Step-by-step explanation:

(This is really going to explain BOTH questions at the same time)

Looking that the problem, the number of views keep going up. There is a multiplier behind this, we just don't know WHAT multiplier it would be. To find that out, divide 1 value by the one before it. I'll do 135 divided by 45 as an example. That would equal three. Now we know the multiplier is 3. So, now we need to multiply 135 by 3 to get 405 views after five days.

(This is really summarizing B, whilst answering A.)
