Answer:

yes.

Step-by-step explanation:

by performing the vertical line test, you can see that the line only goes through one point, so it is a function.

Answer:

yes

Step-by-step explanation:

it passes the vertical line test (you could draw a vertical line anywhere on the graph, and it wouldn't pass through the graph more than once.

3.1 Find roots (zeroes) of : F(x) = x4-7x3+14x2-3x-9

Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 1 and the Trailing Constant is -9.

The factor(s) are:

of the Leading Coefficient : 1

of the Trailing Constant : 1 ,3 ,9

Answer:

37.5

Step-by-step explanation:

14/2=7.5 . Use 7x5=35. 5x0.5=2.5

Answer: $37.50 because you first divide 5 by 2, then you multiply by 15, then you get 37.5

Answer:

a. [tex]Probability = 0.2496[/tex]

b. No, it won't change

Step-by-step explanation:

Represent [tex]the\ head[/tex] with H and [tex]Tail\ with[/tex] T

Such that:

[tex]P(H) = 48\%[/tex]

Solving (a): First head in second trial

First, we determine P(T) i.e. the probability of obtaining a tail

[tex]P(H)+P(T) = 100\%[/tex]

[tex]P(T) = 100\% -P(H)[/tex]

Substitute 48% for P(H)

[tex]P(T) = 100\% -48\%[/tex]

[tex]P(T) = 52\%[/tex]

If the first head is obtained in the second trial, the probability is:

[tex]Probability = P(T\ and\ H)[/tex]

[tex]Probability = P(T)\ and\ P(H)[/tex]

[tex]Probability = P(T)\ *\ P(H)[/tex]

[tex]Probability = 48\%* 52\%[/tex]

[tex]Probability = 0.2496[/tex]

Solving (b): Will it change if tossed three or four times?

Irrespective of the number of times the coin is tossed, the probability of obtaining a head in the second toss will always be the same because the coin has to be tossed twice before the third and the fourth time.

Answer:

5/-2

Step-by-step explanation:

the slope formula is rise over run. the rise is 5 and the run is -2. in decimal form the answer is -2.5

=====================================

Explanation:

Anything in the form A/B = C/D will cross multiply to A*D = B*C

In this case, A = 3, B = 9, C = x and D = 15

So that's why 3/9 = x/15 cross multiplies to 3*15 = 9*x

Answer:

Skyhigh : 40 friends

Jump it up : 90 friends

Step-by-step explanation:

Given that :

Total amount available to spend = $250

JUMP IT UP:

Party set up fee = $70

Amount paid per person = $2

Number of friends = 90

SKY HIGH:

Party set up fee = $50

Amount paid per person = $5

Number of friends = 40

INEQUALITY :

Party setup fee + amount per person * Number of persons ≤ available amount to spend

SKY HIGH:

50 + 5x ≤ 250

5x ≤ 250 - 50

5x ≤ 200

x ≤ 200/5

x ≤ 40

Hence,

Skyhigh = 90 friends

JUMP IT UP:

70 + 2x ≤ 250

2x ≤ 250 - 70

2x ≤ 180

x ≤ 180/2

x ≤ 90

Jump it up = 90

Answer:

(0.449, 0.511) is the range for the percent of students who are excited to take a statistics class

Step-by-step explanation:

First of all, let's check that the sample size is large enough to use normal approximation.

Conditions are;

np > 10

n(1-p) > 10

Now, we have;

n = 1000

p = 48% = 0.48

Thus;

np = 1000 × 0.48 = 480 > 10

Also;

n(1 - p) = 1000 × (1 - 0.48) = 520 > 10. This means the conditions for normal approximation have been fulfilled. Hence we can use the confidence interval formula to get the range of values which is;

CI = p ± z√(pq/n)

We are given a margin of error and thus the confidence interval is at 95%.

Critical value of z at 95% CI is 1.96

Thus;

CI = 0.48 ± 1.96√(0.48 × 0.52/1000)

CI = 0.48 ± 0.031

CI = (0.449, 0.511) is the range for the percent of students who are excited to take a statistics class

Answer:

The increasing interval is [tex]S=(-2,\infty)[/tex]

Step-by-step explanation:

This absolute function has a vertex in x=-2. Now, from this point, the function has a positive slope (increasing), which means for values of x equals to -1,0,1,2,3,...,n.

Therefore the interval will

[tex]S=(-2,\infty)[/tex]
