Answer:
x=42
Step-by-step explanation:
Write the equation.
2(x+50)=16+4x
Spread the parentheses
2x+100=16+4x
Put variables on one side, numbers on the other.
2x-4x=16-100
Add/subtract/multiply/divide the variables with variables and numbers with numbers.
-2x=-84
Make x alone
-x=-42
Flip sides to make x positive
42=x

Jazmin takes a ride share service home from the airport. The ride share service charges $5 as an initial cost to pick her up, and $2.25 for every mile to her final destination. Jazmin's ride home cost a total of $38.75.
Write an equation to represent the situation. Let m represent the number of miles to her home. Do not use any spaces or extra symbols.
Answer:
[tex]5+2.25m=38.75[/tex]
Step-by-step explanation:
Let [tex]m[/tex] represent the number of miles to Jazmin's home.
Initial cost to pick Jazmin [tex]=\$5[/tex]
Cost per mile [tex]=\$2.25[/tex]
Therefore,
Cost for [tex]m[/tex] miles [tex]=\$2.25m[/tex]
Total cost of Jazmin's ride = Initial cost to pick Jazmin + Cost for [tex]m[/tex] miles
= [tex]5+2.25m[/tex]
Also, total cost incurred [tex]=\$38.75[/tex]
So, equation that represent the above situation is [tex]5+2.25m=38.75[/tex]

Answer:
Step-by-step explanation:
We can first solve for the face diagonal. That is [tex]\sqrt{(10^2+5^2)}[/tex]. Notice this will form a right triangle with the vertical side. We get that the face diagonal = [tex]\sqrt{125}[/tex]. Now, we can use Pythagorean theorem again to get the straw length:
[tex]s^2 = 9^2+\sqrt{125}^2[/tex] where s = the straw length.
We can solve that s = [tex]\sqrt{206}[/tex]

en un velocímetro se registra una velocidad de 8.5 m/seg ¿cual sería la velocidad en km/hr?
Answer:
x = 30.6 km/hr
Step-by-step explanation:
Dados los siguientes datos;
Velocidad = 8.5 m/s
Para convertirlo a km /hr;
1 m/s = 3.6 km/hora
8.5 m/s = x km/hora
Multiplicación cruzada, tenemos;
x = 8.5 * 3.6
x = 30.6 km/hora
Velocidad se puede definir como la tasa de cambio en el desplazamiento (distancia) con el tiempo. La velocidad es una cantidad vectorial y, como tal, tiene magnitud y dirección. Matemáticamente, la velocidad viene dada por la ecuación;
[tex] Velocidad = \frac {distancia} {tiempo} [/tex]

A f and g share the same root(s)
B f and g share one root in common but each have another root that is not shared
C f and g share no roots in common
9514 1404 393
Answer:
C f and g share no roots
Step-by-step explanation:
The roots of a polynomial function are the values of x that make factors of the function be zero.
f(x) = x(x +4). The roots of f are -4 and 0.
g(x) = (1/2)(x+3)(x-4). The roots of g are -3 and 4.
f and g share no roots in common.
Find the compound amount and compound interest on $6000 invested at 6%
compounded continously for 6 years. Use e = 2.71828
(Round value of exponential expression upto 4 decimal places.)
Answer:
$8,511.1147
Step-by-step explanation:
Compound interest formula is expressed as;
A = P(1+r)^n
P is the amount invested = $6000
r is the rate = 6% = 0.06
t is the time = 6yrs
A is the compound amount
A = 6000(1+0.06)^6
A = 6000(1.06)^6
A = 6000(1.4185)
A = 8,511.1147
Hence the compound amount to 4dp is $8,511.1147

Which of the following point-slope form equations could be produced with the points (4, 5) and (-3, -5)?
Given:
The two points are (4,5) and (-3,-5).
To find:
The point-slope form equations could be produced with the given points.
Solution:
Slope formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The two points are (4,5) and (-3,-5). So, the slope of the line is:
[tex]m=\dfrac{-5-5}{-3-4}[/tex]
[tex]m=\dfrac{-10}{-7}[/tex]
[tex]m=\dfrac{10}{7}[/tex]
The point slope form of a line is:
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope of the line.
The slope of the line is [tex]m=\dfrac{10}{7}[/tex] is passes through the point (4,5). So, the point slope form is:
[tex]y-5=\dfrac{10}{7}(x-4)[/tex]
The slope of the line is [tex]m=\dfrac{10}{7}[/tex] is passes through the point (-3,-5). So, the point slope form is:
[tex]y-(-5)=\dfrac{10}{7}(x-(-3))[/tex]
[tex]y+5=\dfrac{10}{7}(x+3)[/tex]
Therefore, the point slope form of the given line is either [tex]y-5=\dfrac{10}{7}(x-4)[/tex] or [tex]y+5=\dfrac{10}{7}(x+3)[/tex].

An administrator at a local high school wants to investigate whether there is an association between the grade level of a student (either ninth, tenth, eleventh, or twelfth) and how the student commutes to school (either walks, bikes, takes the bus, receives a ride, or drives). After a chi-square test for association was conducted, the results indicated that the chi-square test statistic was 14.63 with a p-value of 0.2623. Which of the following is the correct interpretation of the p-value in the context of the test?
a. There is a 26.23 percent chance that grade level and how a student commutes to school are independent.
b. There is a 26.23 percent chance that there is no association between grade level and how a student commutes to school.
c. Assuming there is no association between a student's grade level and how the student commutes to school, there is a 26.23 percent chance of finding a test statistic that is 14.63 or larger.
d. Assuming that a student's grade level and the way the student commutes to school are dependent, there is a 26.23 percent chance of finding a test statistic that is 14.63 or larger.
e. Assuming that a student's grade level and the way the student commutes to school are dependent, there is a 26.23 percent chance of finding a test statistic that is 14.63 or smaller.
Answer:
c.
Step-by-step explanation:
The following is how the p-value should be interpreted:
The probability of getting the test statistics value at least as intense as it might have been acquired during the test, assuming the null hypothesis is true, is considered as the p-value.
Null hypothesis
[tex]\mathbf{H_o :}[/tex] A student's grade level has no bearing or association on how they commute to school.
Alternative hypothesis;
[tex]\mathbf{H_1: }[/tex] There is a link between a student's grade level and the way they get to school.
The test statistic's value is 14.63, and the p-value is 0.2636.
As a result, the p-value is interpreted as that of option c in the question.
Answer: C
Step-by-step explanation: Because the p value is less than 0.05 you know that your null hypothesis can be rejected and thus your alternative can have significant evidence to be proven. Thus you can eliminate answer choices B, and E. A and B can be rejected because your p value from your chi square test is telling you the likelihood of your chi square falling in a certain category of the graph.

The two numbers are 3 and 8.
What are squares of a number?Square numbers are numbers that can be multiplied by themselves.
Given that, The sum of the squares of two positive numbers is 73 and the difference of the squares of the numbers is 55.
Let the numbers be x and y, then,
x²+y² = 73
x²-y² = 55
On solving, we get,
x² = 9
x = 3
Putting x = 3 in first equation, we get
3²+y² = 73
y² = 64
y = 8
Hence, the required numbers are 3 and 8.
