Answer:

C

Step-by-step explanation:

Ivy says:

f(1) = -100

f(n) = -100 + 50( n - 1 )f(1) = -100 + 50( 1 - 1 )f(n) = -100 + 50(0 ) anything times 0 is 0!f(1) = -100

You do that with the other numbers in the sequence. 2 = -50, 3 = 0 and so on

When you to n as 1, 2, and 3 they seem to all check out. So Ivy is right!

Andrey says:

f(1) = -100f(1)= -150 +50(1)f(1) = -150 + 50f(1) = -100

That's a little suspicious don't you think that both answers are right..

Essentially they are both the same equation!

So let's simplify Ivy's equation!

f(n) = -100 + 50( n - 1 )

f(n) = -100 + 50n - 50

f(n)= -150 +50n

Which is basically Andrey's equation and they both seem to be right for the sequence! So both of them are right!

Answers

Answer:

1 and 17/25

Step-by-step explanation:

First, you make it into a fraction. So because percents are out of 100, it would be 168/100. Then, you take 100 out of it to get a mixed number, 1 and 68/100, and then simplify 68/100 by dividing both sides by the greatest common factor, which is 4. 68/100÷4=17/25. The answer would be 1 and 17/25.

solve and graph 3t - 12 < -9

Answers

Answer:

x = anything lower than 1

Step-by-step explanation:

x < 1

The constraint of inequality 3t - 12 < -9 is t < 1 and has been plotted on a number line.

What is inequality?

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

Given the inequality

3t - 12 < -9

Add 12 on both sides

3t - 12 + 12 < -9 + 12

3t < 3

Divide by 3 into both sides

t < 1

Hence "The constraint of inequality 3t - 12 < -9 is t < 1".

given f(x) = 1/4 (5-x)^2 what is the value of f(11)

Answers

Answer:

9

Step-by-step explanation:

f(11) means that x = 11 (plug it in)

f(11) = 1/4(5-11)^2

      = 9

The value of f(11) is 9.

The function of a given term is a form of an expression where element of the domain consists of a unique identity and each input value of a function is allocated to only one output value.

From the parameters given;

[tex]\mathbf{f(x) = \dfrac{1}{4}(5 - x)^2}[/tex]

we are to replace x with 11 wherever we see x

[tex]\mathbf{f(11) = \dfrac{1}{4}(5 - 11)^2}[/tex]

[tex]\mathbf{f(11) = \dfrac{1}{4}(-6)^2}[/tex]

[tex]\mathbf{f(11) = \dfrac{1}{4} \times 36}[/tex]

х2 - 6х + 40 = (х + 5

Answers

x^2 - 6x + 40 = x + 5

Solution for quadratic equation

Subtract 40 from both sides.

x^2 - 6x + 40 - 40 = x + 5 - 40

= x^2 - 6x = x - 35

Subtract x from both sides.

x^2 - 6x - x = x - 35 - x

= x^2 - 7x = -35

Rewrite the equation in the form
(x + a)^2 = b

(x - 7/2)^2 = - 91/4

Answer

x = 7/2 + sqroot 91/2,
x = 7/2 - sqroot 91/2

Solution to simplify

Group like terms

x^2 - 6x + 40 = x + 5
x^2 - 6x - x = 5 - 40
x^2 - 7 = -35

In one town, 47% of all voters are Democrats. If three
voters are randomly selected for a survey, what is the
probability that they are all Democrats?

Answers

Answer:

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

Step-by-step explanation:

Step(i):-

Given that the all voters are democrats

The probability that the all voters are democrats

p = 47% =0.47

q = 1-p =1-0.47 = 0.53

Step(ii):-

Let 'X' be the random variable in binomial distribution

[tex]P(X=r) = n_{C_{r} } p^{r} q^{n-r}[/tex]

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

n=3 and r=3

[tex]P(X=3) = 3_{C_{3} } (0.47)^{3} (0.53)^{3-3}[/tex]

[tex]P(X=3) = 1 (0.47)^{3}[/tex]

P(X=3) = 0.1038

Final answer:-

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038
