The slope-intercept form of a line is y= mx + b, where m is the slope and b is the y-intercept. If Shawn knows that the slope of the line is
4 and the line passes through the point (1,-8), which equation should he use to find the y-intercept and what is the y-intercept of the
line?
b = y + mx
O by- mx
=
b = y-m
b = -12
b = -4
b = 2
Answers
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

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.

3.Las soluciones de la ecuación
4.Usa la discriminante para determinar la naturaleza de las raíces de las ecuaciones.
5.Plantea una ecuación cuadrática para la parábola
Answers
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
¿Como encontrar los interceptos con el eje x?
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

A recent survey by the American Automobile Association showed that a family of 2 adults and 2 children on vacation in the United States will pay an average of $247 per day for food and lodging with a standard deviation of $60 per day. Assuming the data are normally distributed,find the nearest hundredth, the Z-scores for each of the following vacation expense amounts. If the data are normally distributed, find the
percentage of families who spent:
a. Less than $167 per day.
b. Less than $367 per day.
c. More than $247 per day.
d. More than $350 per day.
e. Less than $67 per day.
f. Between $200 and $300 per day.
g. Between $360 and $400 per day.
h. More than the median.
i. Less than the mean.
Answers
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%.
Normal Probability DistributionThe 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 z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.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%.

A 2.36 cm3 sample of an unknown metal weighs 18.5 g. what is the sample's density?
Answers
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.

At a circus, tickets cost $6.75 per person. a family of four spent $73.00 on tickets and food. if each person spent an equal amount on food, how much did each person spend on food?
Answers
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.

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°
