Kate wants to spend less than $100 per day to rent a car. A car rents for $45 per day plus $0.25 per mile. Write, solve, and graph an inequality for the amount of miles she is able to drive while staying within her budget.
Answers
To rent a car:
Minimum amount per day= $45
Amount per mile= $0.25
Hence amount spent depends on distance travelled.
If distance travelled= x; fee for travel= 0.25x
Hence finally we need the fare to be less than $100
And fare is $45+0.25x
So the final inequality is 0.25x+45<100.
Hope it helps.

X = 25
Step-by-step explanation:
As, 2x + 60° + 4x = 180° (bc they r supplementry)
So, 6x + 30° = 180°
6x = 180° - 30°
6x = 150°
x = 150/6
x = 25
Therefore, answer = 25

solve system of equations algebraically
Answers
Answer:
(x,y) = -1/2 , 3/2
Step-by-step explanation:
Let y = x +2 ----- (1)
y = -3x ------ (2)
Put equal both sides x +2 = -3x
x = -3x -2
x +3x = -2
4x = -2
x = -1/2 Put it in 2nd equation
Y = -3 (-1/2)
y = 3/2
so (x,y) = -1/2 , 3/2

What is the slope of the line that passes through the points (-2,8) and (-22,8)
Answers
Answer: m = 0
Step-by-step explanation:
Answer:
m=0
Step-by-step explanation:
The slope formula is: m=y1=y2/x2=x1
where (x₁, y₁) and (x₂,y₂) are the points on the line.
The points given are (-2,8) and (-22,8). Therefore,
x1=-2
y1=8
x2=-22
y2=8
Substitute the values into the formula.
m=8-8/-22-2
Solve the numerator. Subtract 8 from 8.
m=0/-22+2
Zero divided by any number is zero, so we automatically know the slope is zero.
m=0
The slope of the line is 0

(20 points) A random sample of =1200 n = 1200 registered voters and found that 620 would vote for the Republican candidate in a state senate race. Let p represent the proportion of registered voters who would vote for the Republican candidate. Consider testing 0:=.50 H 0 : p = .50 :>.50 H a : p > .50 (a) The test statistic is z =
Answers
Answer:
The test statistic is Z = 1.157
Step-by-step explanation:
Given that:
The sample size n = 1200
The sample proportion of those that will vote for the Republican candidate is represented by [tex]\hat p = \dfrac{x}{n}[/tex]
[tex]\hat p = \dfrac{620}{1200}[/tex]
[tex]\hat p =0.5167[/tex]
The null and the alternative hypothesis can be computed as:
[tex]H_o: P=0.50 \\ \\ H_a :P>0.50[/tex]
The formula for the one-sample Z-test for the population proportion can be expressed as:
[tex]Z = \dfrac{\hat p - P_o}{\sqrt{\dfrac{P_o(1-P_o)}{n}}}[/tex]
[tex]Z = \dfrac{0.5167 - 0.5}{\sqrt{\dfrac{0.5(1-0.5)}{1200}}}[/tex]
[tex]Z = \dfrac{0.0167}{\sqrt{\dfrac{0.5(0.5)}{1200}}}[/tex]
[tex]Z = \dfrac{0.0167}{\sqrt{\dfrac{0.25}{1200}}}[/tex]
[tex]Z = \dfrac{0.0167}{\sqrt{2.08333333\times10^{-4}}}[/tex]
Z = 1.157
Testing the hypothesis, from the information given, it is found that the test statistic is z = 1.157.
The null hypothesis is:
[tex]H_0: p = 0.5[/tex]
The alternative hypothesis is:
[tex]H_1: p > 0.5[/tex]
The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which:
[tex]\overline{p}[/tex] is the sample proportion. p is the proportion tested at the null hypothesis. n is the sample size.For this problem, the parameters are: [tex]p = 0.5, n = 1200, \overline{p} = \frac{620}{1200} = 0.5167[/tex]
Hence, the value of the test statistic is:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.5167 - 0.5}{\sqrt{\frac{0.5(0.5)}{1200}}}[/tex]
[tex]z = 1.157[/tex]
The test statistic is z = 1.157.

Como pasar una potencia de negativa a positiva ?
Answers
Answer:
Cuando tenemos un exponente negativo hay que INVERTIR LA BASE para pasar a exponente positivo. Fíjate que el poner el inverso de la base no significa cambiar el signo de la misma. Al final el signo del resultado dependerá de si el exponente es par o impar. Con las fracciones ocurre lo mismo.
