What is one of the zeros of the function f (x) = x^2– X – 12?

Answer:

Multiply each side by 6

Step-by-step explanation:

27 = m/6 - 3

Add 3 to each side

27+3 = m/6 - 3+3

30 = m/6

Multiply each side by 6

30*6 = m/6*6

180 = m

Answer:

what is this in? please let me kno2

The actual temperature is 5 degrees Fahrenheit if the temperature adjusted for wind chill is -15 degrees Fahrenheit.

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

We have the relationship between the actual air temperature x (in degrees Fahrenheit) and the temperature y adjust for wind chill (in degrees Fahrenheit, given by 20 mph wind) is given as:

y = -22 + 1.4x

When.

The temperature adjusted for wind chill, y  = -15 degrees Fahrenheit
Put this value in the given linear equation, we get:

-15 = -22 + 1.4x

-15 + 22 = 1.4x    (add 22 on both sides)

7 = 1.4x

x = 5 degrees Fahrenheit  (divide by 1.4 on both sides)

Thus, the actual temperature is 5 degrees Fahrenheit if the temperature adjusted for wind chill is -15 degrees Fahrenheit.

Answer:

0.8974 = 89.74% probability that the person actually has the disease.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Positive test.

Event B: Has the disease.

Probability of a positive test:

0.7 of 0.2(has the disease).

0.02 of 100 - 20 = 80%(does not have the disease). Thus:

[tex]P(A) = 0.7*0.2 + 0.02*0.8 = 0.156[/tex]

Probability of a positive test and having the disease:

0.7 of 0.2. So

[tex]P(A \cap B) = 0.7*0.2 = 0.14[/tex]

What is the probability that the person actually has the disease?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.14}{0.156} = 0.8974[/tex]

0.8974 = 89.74% probability that the person actually has the disease.

Answer:

Step-by-step explanation:

First of all, to keep our numbers manageable, we are going to let year 2001 = 0 so year 2012 = 11.  The coordinates that result from these years/population numbers are (0, 22200) and (11, 13950). Since this linear, we can plug those 2 coordinate pairs into the slope equation to find the rate at which the population is decreasing in people per year:

[tex]m=\frac{13950-22200}{11-0}=\frac{-8250}{11}=-750\frac{people}{year}[/tex] That means that the town is losing people at the rate of 750 per year. We can use that slop along with one of the coordinate points to write the linear equation representing this situation:

[tex]y-22200=-750(x-0)[/tex] and

y = -750x + 22200. That answers part A.

Now for B we need to find y when x = 13 (remember we let year 2001 = 0, so year 2014 = 13):

y = -750(13) + 22200 so

y = 12450 people in the year 2014

One of the basic tenets of statistics that every student learns in about the second week of intro stats is that in a skewed distribution, the mean is closer to the tail in a skewed distribution. So in a right skewed distribution (the tail points right on the number line), the mean is higher than the median.

Step-by-step explanation:

The distribution is said to be right-skewed. In such a distribution, usually (but not always) the mean is greater than the median, or equivalently, the mean is greater than the mode; in which case the skewness is greater than zero.

Answer:

x > 9

Step-by-step explanation:

31 < 3x + 4

Treat the < sign the same way you do with =

So first minus 4

31 < 3x + 4

-4 -4

27 < 3x

Divide both sides by 3

9 < x

If you want x on the other side just flip the symbol

x > 9

7x - 18 = 4x + 21

Step 2: Solve for x

Answer:

x = 13

Step-by-step explanation:

7 x - 18 = 4 x + 21

Subtract 4x on both side

7x - 4 x - 18 = 4x - 4x + 21

3 x - 18 = 21

Add 18 on each side

3 x - 18 + 18 = 21 + 18

3 x = 39

Divided each side by 3

3 x / 3 = 39 / 3

x = 13

Answer:

50 hot dogs

150 sodas

Step-by-step explanation:

set up a system of equations where 'h' = # hot dogs sold and '3h' = # sodas sold

h + s = 200

s = 3h

h + 3h = 200

4h = 200

h = 50

s = 200-50 or 150

Answer:

leslie will hace 587 score and

jackson =587+31= 618

Step-by-step explanation:

1134 -31/2 = leslie

leslie + 31 = 618

Answer:

see below

Step-by-step explanation:                          6  24  10  18

Leslie  = x points

Jackson scored 38 more points than Leslie    Jackson =  x + 38 points

Together, Jackson and Leslie scored 1134       Sum of both scores

  Leslie + Jackson = 1134

      x     +   x + 38   = 1134              solve for x Leslie's number of points

            2x  + 38  =  1134

     2x  + 38 - 38 =  1134 -38

              2x  =  1096

            2x/2 =  1096 / 1

                x  =   1096 /2

                x  =     548          Leslie points

          Jackson =  Leslie's points + 38 points

                         =    548 + 38

          Jackson's points  =  586 points

Answer:

[tex]C(d) = \frac{1}{5}d + 320[/tex]

Step-by-step explanation:

Given

[tex]d \to miles[/tex]

[tex]C \to cost[/tex]

So:

[tex](d_1,C_1) = (500,420)[/tex] --- May

[tex](d_2,C_2) = (620,444)[/tex] --- June

Required

Express as a function

Start by calculating the slope (m)

[tex]m = \frac{\triangle C}{\triangle d}[/tex]

[tex]m = \frac{444-420}{620-500}[/tex]

[tex]m = \frac{24}{120}[/tex]

Simplify

[tex]m = \frac{1}{5}[/tex]

The equation is:

[tex]C(d) = m(d - d_1) +C_1[/tex]

[tex]C(d) = \frac{1}{5}(d - 500) +420[/tex]

[tex]C(d) = \frac{1}{5}d - 100 +420[/tex]

Take LCM

[tex]C(d) = \frac{1}{5}d + 320[/tex]

After 17 years, Serenity has $778 more than Avery

The formula for calculating the compound amount is expressed according to the formula;

[tex]A=P(1+\frac{r}{n} )^{nt}\\[/tex]

For Avery;

P = $3,800

rate = 5 1/2 % = 0.055

time = 17 years

n = 12 (monthly compounding)

Substitute into the formula to have:

[tex]A=3800(1+\frac{0.055}{12} )^{12(17)}\\A=3800(1+0.00458)^{204}\\A=3800(1.00458)^{204}\\A=3800(2.5401)\\A = \$9,652.22[/tex]

Hence the amount that will be in Avery's account after 17years is $9,652

For Serenity;

P = $3,800

rate = 6 1/8 % = 0.06125

time = 17 years

n = 1 (continuous compounding)

Substitute into the formula to have:

[tex]A=3800(1+\frac{0.06125}{1} )^{1(17)}\\A=3800(1+0.06125)^{17}\\A=3800(1.06125)^{17}\\A=3800(2.7473)\\A = \$10,439.62[/tex]

Hence the amount that will be in Serenity's account after 17years is $10,430.

Amount Serenity have more than Avery = $10,430 - $9652 = $778
