A study has been done to determine to see if the level of education determines how often people move between different states in America. If a person from the survey that attended college is randomly selected what is the probability that they also lived in 2 or more states during their life? P(2 state or more | College Degree)

Answer:

Two real roots

Step-by-step explanation:

The portion of the quadratic formula that determines the number of roots is

b² - 4ac

If it's positve there are two real roots

If it's zero there is one real root

If it's negative there are no real roots

------------------------------

b² - 4ac = 7² - 4(3)(-8)

b² - 4ac =  49 + 96

b² - 4ac =  145

Two real roots since 145 is positive

The quadratic equation has two real zeroes

What is quadratic equations?

The polynomial equations of degree two in one variable of type f(x) = ax2 + bx + c = 0 and with a, b, c, and R R and a 0 are known as quadratic equations. It is a quadratic equation in its general form, where "a" stands for the leading coefficient and "c" for the absolute term of f. (x). The roots of the quadratic equation are the values of x that fulfill the equation (, ).

It is a given that the quadratic equation has two roots. Roots might have either a real or imaginary nature.

What is quadratic formlua?

D=b²-4ac

x=(-b±√(b²-4ac))/2a

y = 3x² + 7x - 8

On comparing with ax²+bx+c, we get

a=3, b=7 and c=-8

Using Quadratic formula

D=b²-4ac

   =7²+4x3x8

   =49+96

     =145>0

Hence it has real zeroes

Answer: Choice B

They traveled 250 miles in 4 hours. Their speed was 62.5 mph.

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

Explanation:

Start at point X. Draw a horizontal line straight across until you reach the y axis. You should arrive at y = 250. This tells us that they traveled 250 miles.

Go back to point X. Draw a vertical line until you reach the x axis. You should reach x = 4. This indicates 4 hours.

Pairing up the two values together means they traveled 250 miles in 4 hours. Divide the distance over time to get the speed

speed = distance/time = 250/4 = 62.5 miles per hour

--------

Side note: unfortunately your teacher chose the label uppercase X for the point, which may be a bit confusing since it could clash with the lowercase x along the horizontal axis.

Another note: the speed represents the slope of the line

Answer:

GARDEN = 9 years

TREE = 99 years

Step-by-step explanation:

the following equation can be derived from the question

age of oak tree = 11x

age of garden = x

11x + x = 108

12x = 108

x = 9

oak tree = 11 x 9 = 99

Answer:

Option A. –2 – 2√2

Step-by-step explanation:

√8 / √2 – 2

The above expression can be simplified as follow.

√8 / (√2 – 2)

Rationalise by multiplying the numerator and denominator with the conjugate of (√2 – 2) i.e (√2 + 2). This is illustrated below:

√8 / (√2 – 2) × (√2 + 2)/(√2 + 2)

√8(√2 + 2) / (√2 – 2)(√2 + 2)

√16 + 2√8 / 2 + 2√2 – 2√2 – 4

√16 + 2√8 / 2 – 4

√16 + 2√8 / –2

Recall

√16 = 4

√8 = √(4×2) = √4 × √2 = 2√2

Thus,

√16 + 2√8 / –2 = 4 + 2×2√2 / –2

= (4 + 4√2) / –2

= 4/–2 + 4√2/–2

= –2 – 2√2

Therefore,

√8 / (√2 – 2) = –2 – 2√2

Thus, option A gives the correct answer to the question.

Answer:

[tex]volume \ of \ sphere = \frac{4}{3} \pi r^3 \\\\1 =\frac{4}{3} \pi r^3\\\\r^ 3 = \frac{3}{4\pi} \\\\r = (\frac{3}{4\pi })^{\frac{1}{3} } \\\\r = 0.62ft\\\\diameter = 2 * 0.62 = 1.24ft[/tex]

Answer:

1.24 ft

Step-by-step explanation:

the volume of sphere = 4/3π.r³ = 1

=> r³ = 3/(4π)= 3/(12.56) = 0.239

r = ³√0.239

r = 0.62

d = 2×0.62 = 1.24 ft

Answer:

Mean = 4.7

Mode = 5

Median = 5

Step-by-step explanation:

Mean = Σfx / Σf

Σfx = (3*4) + (4*5) + (5*7) + (6*2) + (7*2) = 93

Σf = (4+5+7+2+2) = 20

Mean = 93 / 20

= 4.65

= 4.7

Mode = highest occurring = vlaue with highest frequency = 5

Median :

20 / 2 = 10

Value corresponding to the 10th term = 5
