Step-by-step explanation:

You have 1 item. You have another item. That means you have 2 items.

Answer:

-1 - 17x

Step-by-step explanation:

Firstly you arrange the like terms as follows:

(17 - 18) (- 12x - 5x)

Then you work it out:

17 - 18 = -1

-12x - 5x = -17x

After you combine the answers:

-1 -17x

Finally you get:

-1 - 17x

Using the normal distribution, the percentages are given as follows:

a. 9.18%.

b. 97.72%.

c. 50%.

d. 4.27%.

e. 0.13%.

f. 59.29%.

g. 2.46%.

h. 50%.

i. 50%.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation for this problem are given as follows:

[tex]\mu = 247, \sigma = 60[/tex]

For item a, the proportion is the p-value of Z when X = 167, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (167 - 247)/60

Z = -1.33.

Z = -1.33 has a p-value of 0.0918.

Hence the percentage is of 9.18%.

For item b, the proportion is the p-value of Z when X = 367, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (367 - 247)/60

Z = 2.

Z = 2 has a p-value of 0.9772.

Hence the percentage is of 97.72%.

For item c, the proportion is one subtracted by the p-value of Z when X = 247, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (247 - 247)/60

Z = 0.

Z = 0 has a p-value of 0.5.

1 - 0.5 = 0.5.

Hence the percentage is of 50%.

For item d, the proportion is one subtracted by the p-value of Z when X = 350, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (350 - 247)/60

Z = 1.72

Z = 1.72 has a p-value of 0.9573.

1 - 0.9573 = 0.0427.

Hence the percentage is of 4.27%.

For item e, the proportion is the p-value of Z when X = 67, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (67 - 247)/60

Z = -3.

Z = -3 has a p-value of 0.0013.

Hence the percentage is of 0.13%.

For item f, the proportion is the p-value of Z when X = 300 subtracted by the p-value of Z when X = 200, hence:

X = 300:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (300 - 247)/60

Z = 0.88.

Z = 0.88 has a p-value of 0.8106.

X = 200:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (200 - 247)/60

Z = -0.78.

Z = -0.78 has a p-value of 0.2177.

0.8106 - 0.2177 = 0.5929.

Hence the percentage is of 59.29%.

For item g, the proportion is the p-value of Z when X = 400 subtracted by the p-value of Z when X = 360, hence:

X = 400:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (400 - 247)/60

Z = 2.55.

Z = 2.55 has a p-value of 0.9946.

X = 360:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (360 - 247)/60

Z = 1.88.

Z = 1.88 has a p-value of 0.97.

0.9946 - 0.97 = 0.0246.

Hence the percentage is of 2.46%.

For items h and i, the distribution is symmetric and the mean and the median are equal, hence both percentages are 50%.

The equation is d + 3h = $13

The cost of each hamburger is $3.5

From the question, we are to write and solve the equation for the problem.

From the given information,

Danie purchases one hot dog $2.50

and

3 hamburgers

and

He spent $13 total

Let d represent hot dog

and

h represent hamburger

Then,

d = $2.50

We can write that

d + 3h = $13

$2.50 + 3h = $13

3h = $13 - $2.50

3h = $10.5

h = $10.5/3

h = $3.5

Hence, the cost of each hamburger is $3.5

Answer:25

Step-by-step explanation:

Answer:

$11.50

Step-by-step explanation:

6.75 times 4 is 27

$73-27 is 46

46 divided by 4 is 11.5

Answer:

$11.50

Step-by-step explanation:

Total spent = Food + Tickets

The cost of the tickets times the number of people

6.75 x 4 = $27.00 for tickets

then the total number of dollars spent in total subtracted by the amount for tickets

73 - 27 = $46 for food

$46 / 4 people = 11.50

So each person spent 11.50 on food.

Answer:

mean = 23

median = 22.50

mode = 20

range = 7.5

Step-by-step explanation:

mean is the total / n

total = 20+20+22.50+25+27.50 = 115

n= 5

mean = 115/5 = 23

median you'll arrange the numbers in ascending order and pick the middle one and its 22.50

20, 20, [22.50], 25, 27.50

mode is the number that is repeated mostly and it was 20.

range is max - min

max is 27.50

min is 20

range = 27.50 - 20

range = 7.50

Answer: the x value of the ordered pair is 0

Answer:

x = 50°

Step-by-step explanation:

draw a line through B parallel to the 2 given parallel lines , then

the upper angle at B and 150° are same- side interior angles and sum to 180°

upper angle = 180° - 150° = 30°

the lower angle at B and 160° are same- side interior angles and sum to 180°

lower angle = 180° - 160° = 20°

Then

x = upper angle + lower angle = 30° + 20° = 50°

The density of the sample is 796.61 kg/m^3.

According to teh given question.

The weight of the metal is 18.5g

The volume of the sample is 2.36 cm^3 or 0.00000236

Since, we know that

Weight = mass × acceleration due to gravity

⇒ 18.5g = mass of the metal × 9.8

⇒ 18.5g/1000 = mass of the metal × 9.8

⇒ mass of the metal = 0.00188kg

Therefore,

the density of the sample

= 0.00188/0.00000236

= 796.61 kg/m^3

Hence, the density of the sample is 796.61 kg/m^3.

The equation that can be used to find the y-intercept of the line is

b = y - mx, and the y-intercept for this equation will be -12

In this question, It is given that a line passes through a given point (1,-8), and the slope of the line is given 4. We know the equation of Slope-point form : (y - y₁) = m(x - x₁), Where m = slope = 4 and (x1,y1) = (1,-8)

Now, putting these values into the slope-point form equation, We get :

            => (y - y₁) = m(x - x₁)

            => (y - (-8) = 4(x - 1)  => (y +8) = 4x -4

            => y = 4x -12          ---> Equation (1)

We got the slope-intercept form for the following situation.

We can find out the y-intercept value by comparing the

            => y = mx + b to Equation (1).

            => b = -12

Hence, b = y - mx will be used to find out the y-intercept and the y-intercept for this line will be -12

A histogram is a visual depiction of data points arranged into ranges that the user has chosen. The histogram, which resembles a bar graph in appearance, groups numerous data points into comprehensible ranges or bins in order to compress a data series into an easily understood visual. In statistics, histograms are frequently used to show the frequency of a particular type of variable within a given range. Analysts can customize histograms in a number of different ways. They are able to alter the space between buckets. The sample given above has eight buckets with a ten-bucket spacing. Four buckets with a 20-second interval could be used instead.

Utilizando la formula de Bhaskara obtenemos los interceptos del eje x que son en x = 0.

La cuadratica con las dadas raices es:

f(x) = x^2 + 64

Primero tenemos la función cuadratica:

f(x) = 2x^2 - 6x + (9/2)

Primero, debemos encontrar las soluciones a la ecuación:

2x^2 - 6x + (9/2) = 0

Esto nos dara los interceptos con el eje x.

Usando la formula de Bhaskara obtendremos:

x = ( 6 ± √( (-6)^2 - 4*(9/2)*2 )/(2*2)

x = (6  ± 0)/4

Entonces tenemos dos interceptos del eje x en el mismo punto, que es x = 6/4 = 3/2

2) Ahora nos dan dos raices, que son x = 8 y x = -8

Recordar que si nos dan dos raices a y b, entonces una cuadratica con esa raices será:

f(x) = A*(x - a)*(x - b)

Donde A es el coeficiente lider de la cuadratica. En este caso no nos dan un valor de A, por lo que asumimos es 1.

Entonces esta cuadratica será:

f(x) =(x - 8)*(x + 8)

Expandiendo:

f(x) = x^2 + 64
