Jillian is an analyst for a ride sharing app that connects users with drivers. She wonders if drivers in Dallas are more or less likely to cancel rides than drivers in Houston. She takes a random sample of 1000 rides from Dallas and finds that 30 were cancelled. A random sample of 1000 rides from Houston shows 24 cancelled rides. She used these results to test H: Pp = PH versus H, :pp + PH. The test statistic was z = 0.83 and the P-value was approximately 0.41. Assume that all conditions for inference were met. At the a = 0.01 level of significance, is there sufficient evidence to conclude that the proportion of cancelled rides is different between the two cities?
A Yes, since the P-value is greater than 0.01.
B Yes, since the test statistic is greater than 0.01.
C No, since the P-value is greater than 0.01
D No, since the test statistic is greater than 0.01.
Answer:
C No, since the P-value is greater than 0.01
Step-by-step explanation:
Since in the given situation we assume that all the conditions are ,met
And, at the a = 0.01 significance level we that that the proportion of the cancelled rides between the two cities would not sufficient as the P value is more than 0.001
Therefore the correct option is c.
Condense the log equation: 4 log x + log y - 5 log z
Answer:
The condensed log equation is: [tex]\log{\frac{x^4y}{z^5}}[/tex]
Step-by-step explanation:
We use these following logarithm properties to solve this question:
[tex]a\log{x} = \log{x^a}[/tex]
[tex]\log{a} + \log{b} = \log{ab}[/tex]
[tex]\log{a} - \log{b} = \log{\frac{a}{b}}[/tex]
In this question:
[tex]4\log{x} = \log{x^4}[/tex]
[tex]5\log{5} = \log{z^5}[/tex]
So
[tex]4\log{x} + \log{y} - 5\log{z}[/tex]
Becomes:
[tex]\log{x^4} + \log{y} - \log{z^5}[/tex]
Now applying the addition and subtraction properties, we have:
[tex]\log{\frac{x^4y}{z^5}}[/tex]
The condensed log equation is: [tex]\log{\frac{x^4y}{z^5}}[/tex]

Answer:
A.
Step-by-step explanation:
x^2 + 6x + 10 cannot be factored
x^2 + 3x -4 = (x-1)(x+4)
x^2 - 3x -4 = (x+1)(x-4)
x^2 + 6x +5 = (x+1)(x+5)
Answer: x² + 6x + 10
Step-by-step explanation:
The four can be factored by the set of real numbers, except the first one.
- x² + 3x - 4 can be factor as (x + 4)(x - 1)
- x² - 3x - 4 can be factor as (x - 4)(x + 1)
- x² + 3x - 4 can be factor as (x + 4)(x - 1)
And the first one, the number is 10, the factos of 10 is 1,2,5,10, none of the factors would apply the situation 6x.
A rectangular flower garden in Samantha's backyard has 260 feet around its edge. The width of the garden is 60 feet.
What is the length of the garden?
Answer:
100 - 20 = 80 Length Of the Garden
Step-by-step explanation:
So You Can do 20 Ft Minus 100 Because 100 is the Total so Heres a Graph To Show You
Total= 100 Ft
Width= 20
Length=?
Total - Width = Length
100 - 20 = 80 Length Of the Garden

You want to find the surface area for this problem. SA=2lw+2lh+2hw
Step-by-step explanation:
L=2.5
W=7.4
H=9.6
SA=2lw+2lh+2hw
SA=2(2.5x7.4)+2(2.5x9.6)+2(9.6x7.4)
SA=37+142.08+48
SA=227.08in^2
divide 270 in the ratio 3:2:1
3 + 2 + 1 = 6
270 ÷ 6 = 45
45 × 3 = 135
45 × 2 = 90
45 × 1 = 45
3 : 2 : 1
135 : 90 : 45

How many and what type of solution(s) does the equation have?8p^2=24p−10
Answer:
2 real solutionsStep-by-step explanation:
to understand thisyou need to know about:discriminantPEMDAStips and formulas[tex]D=b^{2}-4ac[/tex]D>0 (2 real solutions)D=0 (1 real solution)D<0 (2 imaginary solutions) or (no real solutions)let's solve:move left hand side expressions to right hand side and change its sign:8p²-24p+10=0divide both sides by 2 :4p²-12p+5=0the quadratic equation standard form is
ax²+bx+c=0therefore we get

substitute the value of a,b and c into the discriminant: D=-12²-4.4.5simplify square:144-4.4.5simplify multiplication:144-80simplify substraction:64since we got D>0
therefore

Answer:
y = x - 8
Step-by-step explanation:
y = mx + b
M is your slope, 1. 1x can be rewritten as x.
Your Y intercept is B, therefore -8.
y = x - 8. When you plug in the numbers.
Determine whether the following functions with their specified domain and range is injective, surjective, and bijective. If you determine that a given function with its specified domain and range is injective, surjective, or bijective, you do not need to prove it. On the other hand, if you determine that a given function with its specified domain and range fails to be injective, surjective, or bijective, you MUST provide a counter example.
a. f: R → R defined by f(x) = x^4 + 1.
b. f: R (1,0) defined by f(x) = x^4 + 1
c. f: R + R defined by f(x) = 2^x.
d. f: R (1,0) defined by f(x) = 2^x + 1.
Answer:
Step-by-step explanation:
[tex]\text{Given that:}[/tex]
[tex]f: \mathbb{R} \to \mathbb{R}[/tex] [tex]\text{which is de-fined by : } f(x) = x^4 + 1[/tex]
[tex]\mathbf{f \ is \ not \ injective}[/tex]
[tex]\mathtt{counterexample:}[/tex]
[tex]Assume \ x =1, y = -1 \\ \\ f(x) = 1^4 + 1= 2 \\ \\ f(y) = (-1)^4 + 1 = 2[/tex]
[tex]Hence \ f(x) = f(y) , but \ x \ne y[/tex]
[tex]Also;[/tex] [tex]f[/tex] [tex]\text{ is not surjective.}[/tex]
[tex]Take (y )= -10 \ \varepsilon \ \mathbb{R}[/tex]
[tex]\text{But there is no pre-image x such that}[/tex] [tex]f(x) = y[/tex]
[tex](b)[/tex]
[tex]f: \mathbb{R} \to (1, \infty) \ \ \text{which is de-fined as} \ f(x) = x^4 + 1 \\ \\ \text{f is injective and surjective and; thus bijective}[/tex]
[tex](c) \\ \\ f : \mathbb{R} \to \ \mathbb{R} \text{which can be de-fined as} \ f(x) = 2^x \\ \\ \text{f is injective and f is no surjective} \\ \\ \mathtt{counterexample:} \\ \\ Assume \ 2 \ \varepsilon \ \mathbb{R} \\ \\ whereas; 2^x = -2 \\ \text{which implies that }: \implies x = \dfrac{log_x(-2)}{log 2} = not \ de'fined[/tex]
[tex](d) f : \mathbb{R} \to (1 , \infty) , \ \text{which is de'fined by} \ \ f(x) = 2^x+1 \\ \\ \text{Thus; f is injective, surjective, and bijective}[/tex]
The proportion of California residents who reported insufficient rest or sleep during each of the preceding 30 days is 8.0%, while this proportion is 8.8% for Oregon residents. These data are based on simple random samples of 11,545 California and 4,691 Oregon residents.
(a) Conduct a hypothesis test to determine if these data provide strong evidence the rate of sleep deprivation is different for the two states.
(b) It is possible the conclusion of the test in part (a) is incorrect. If this is the case, what type of error was made?
Step-by-step explanation:
We start by stating the null hypothesis
H0: p1 = p2
No difference is existent
H1: p2 not equal to p2
There is a difference
We find the z statistic using microsoft excel or using the formula in the attachment
= -1.68
From the normal table, p value = 0.099
The p value is greater than 0.05 so we fail to reject the null hypothesis and conclude there is no difference
B. If answer in part a is incorrect then we have made a type ii error. A type 2 error occurs when we accept a false null hypothesis.

<5 is a complement of <6 and m<5 = 59 degrees. Find m<6.
A pair of complementary angles, when added, equal 90. So if <5 is 59 degrees, what do you do to find <6? You subtract 59 with 90.
90-59=31
So <6 is 31 degrees.

SOMEONE PLEASE ANSWER AND EXPLAIN I’LL MARK BRAINLIEST THANK YOU
Answer:
20 visits.
Step-by-step explanation:
Fitness Universe has a 1 time payment of $50, and each visit will cost $5.50
Non-members pay $8 per visit. Let each visit be signified by the variable, v. Set the equation:
5.50v + 50 = 8v
Isolate the variable, v. Note the equal sign, what you do to one side, you do to the other. Subtract 5.50v from both sides:
5.50v (-5.50v) + 50 = 8v (-5.50v)
50 = 8v - 5.50v
50 = 2.50v
Isolate the variable, v. Divide 2.50 from both sides:
(50)/2.50 = (2.50v)/2.50
v = 50/2.50
v = 20
