12 in the singers catagory.  50 in the middle catagory, 18 in the band catagory.

Step-by-step explanation:

PLEASE GIVE THANKS AND BRAINLIEST, TRYING TO RANK UP

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.

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.

Answer:I think that it would be either b or c

Answer:

Step-by-step explanation:

the quadratic equation standard form is

therefore we get

-------------------------------

since we got D>0

therefore

the quadratic equation has 2 real solutions

Answer:

∠2 = 150°, it is a supplementary angle to 30°

∠3 = 30°, it is an alternate angle to 30°

∠4 = 150°, it is a supplementary angle to 30°

∠5 = 30°, it is an alternate angle to 30°

∠6 = 150°, it is a supplementary angle to 30°

∠7 = 30°, it is an alternate angle to 30°

∠8 = 150°, it is a supplementary angle to 30°

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.

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]

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.

3 + 2 + 1 = 6

270 ÷ 6 = 45

45 × 3 = 135

45 × 2 = 90

45 × 1 = 45

3 : 2 : 1

135 : 90 : 45

Answer:

Its the last one because the sign is pointing to the right (x) and it has a line underneath, which would be a closed dot so therefore, the last one is the amswer

Answer:

2 ∠ x

Step-by-step explanation:

The graph is going right of 2 which means x is greater than 2.

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

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.

The value of x in the equation, (3x + 30), is 10.

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:

227.08in^2

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

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

Stuart must visit 20 times to break even, in which it will become cheaper after the 20th visit.
