SinB = CosA

CosA = SinB

CosB = SinA

Answer:

C) Infinitely many

Step-by-step explanation:

7x+3-x=3(1+2x)

6x+3=3+6x

Subtract 3 from both sides

6x = 6x

Infinitely many solutions

Answer:

6/52 is a reasonable answer

Answer:

[tex]10 {}^{2} - 11(10 - 2) \\ 100 - 11 \times 8 \\ 100 - 88 \\ = 12[/tex]

Complete question :

According to the National Association of Realtors, it took an average of three weeks to sell a home in 2017. Suppose data for the sale of 39 randomly selected homes sold in Greene County, Ohio, in 2017 showed a sample mean of 3.6 weeks with a sample standard deviation of 2 weeks. Conduct a hypothesis test to determine whether the number of weeks until a house sold in Greene County differed from the national average in 2017. Useα = 0.05for the level of significance, and state your conclusion

Answer:

H0 : μ = 3

H1 : μ ≠ 3

Test statistic = 1.897

Pvalue = 0.0653

fail to reject the Null ; Hence, we conclude that their is no significant to accept the claim that number I weeks taken to sell a house differs.

Step-by-step explanation:

Given :

Sample size, n = 40

Sample mean, x = 3.6

Population mean, μ = 3

Standard deviation, s = 2

The hypothesis :

H0 : μ = 3

H1 : μ ≠ 3

The test statistic :

(xbar - μ) ÷ (s/√n)

(3.6 - 3) / (2/√40)

0.6 / 0.3162277

Test statistic = 1.897

Using T test, we can obtain the Pvalue from the Test statistic value obtained :

df = n - 1; 40 - 1 = 39

Pvalue(1.897, 39) = 0.0653

Decison region :

If Pvalue ≤ α ; Reject the null, if otherwise fail to reject the Null.

α = 0.05

Pvalue > α ; We fail to reject the Null ; Hence, we conclude that their is no significant to accept the claim that number I weeks taken to sell a house differs.

Answer:

The exponential form of [tex]\log_{4} 4 = 1[/tex] is [tex]4 = 4^{1}[/tex].

Step-by-step explanation:

After some research in the web, we find that correct statement is:

Rewrite [tex]\log_{4} 4 = 1[/tex] in exponential form.

We obtain its exponential form by using the definition of logarithm:

[tex]4^{\log_{4} 4} = 4^{1}[/tex]

[tex]4 = 4^{1}[/tex]

Answer:

11

Step-by-step explanation:

The line plot shows how many people read many many books with the number of "x"s above each number. So, through this graph,  we see that 0 people read 0 books, 5 people read 1 book, 3 people read 2 books, 6 people read 3 books, 3 people read 4 books, 3 people read 5 books, 2 people read 6 books, 2 people read 7 books, and 1 person read 8 books. The problem asks how many people read 4 or more books. So, we add up all the people that read 4 or more books shown on the graph, which is 4, 5, 6, 7, and 8.

3 people read 4 books, 3 people read 5 books, 2 people read 6 books, 2 people read 7 books, and 1 person read 8 books.

3 + 3 + 2 + 2 + 1 = 11. 11 students read 4+ books.

Answer:

314.96

586.74

Step-by-step explanation:

Answer:314.96; 586.74

Step-by-step explanation:

1 inch = 25.4 millimeters

12.4 x 25.4 = 314.96

23.1 x 25.4 = 586.74

Multiply the number of inches by 25.4 to convert to millimeters :).

Nice

Step-by-step explanation:

but tons of wut'

Answer:

We use Pythagoras' theorem:

[tex] \bf {AC}^{2} = {AB}^{2} + {BC}^{2} \\ \\ \bf {AC}^{2} = ( \frac{12}{13})^{2} + ( \frac{5}{13} )^{2} \\ \\ \bf {AC}^{2} = \frac{ {12}^{2} }{ {13}^{2} } + \frac{ {5}^{2} }{ {13}^{2} } \\ \\ \bf {AC}^{2} = \frac{144}{169} + \frac{25}{169} \\ \\ \bf {AC}^{2} = \frac{169}{169} \\ \\ \bf {AC}^{2} = 1 \\ \\ \bf AC = \sqrt{1} \Rightarrow \red{ \boxed{ \bf AC = 1} } [/tex]

Answer:

AC = 1

Step-by-step explanation:

This is Pythagoras' theorem, which states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse.

⇒ Th.P ⇒ AC² = AB² + BC²

<=> AC² = (12/13)² + (5/13)²

<=> AC² = 144+25/169

<=> AC² = 169/169

<=> AC² = 1

⇒ AC = √1 = 1.

Answer:

D. [tex] y - y_0 = m(x - x_0) [/tex].

Step-by-step explanation:

The equation of a line can be written in the point-slope form if we know the the coordinates of a point the line passes through which is [tex] (x_0, y_0) [/tex]. And if we also know the slope = m of the line.

Therefore, the point-slope equation is given as:

[tex] y - y_0 = m(x - x_0) [/tex]

Answer:

Answer: five and a half weeks.

Step-by-step explanation: 20 times 2 (the twice a week deposit) = 40. 220 (the negative checking) divided by 40 (the deposits each week) equals 5.5

Answer:

x=5, y=6

Step-by-step explanation:

By the HL theorem, if the corresponding hypotenuses and one side of two triangles are equal, they are congruent.

So put the hypotenuses equal to each other, and put the side lengths equal to each other.

3x-2=2y+1

x=y-1

Sub 'y-1' into the first equation for x:

3(y-1)-2=2y+1

3y-3-2=2y+1

y=6

x=y-1=6-1=5

Answer:

A. The range of both data sets is 40

Step-by-step explanation:

Range = the maximum value - the minimum value

✔️For the Seventh-Grade Students' data set,

Maximum value = 45

Minimum Value = 5

Range = 45 - 5 = 40

✔️✔️For the Eight-Grade Students' data set,

Maximum value = 45 (the value at the whisker to your far right)

Minimum Value = 5 (value indivl ated by the whisker on your far left)

Range = 45 - 5 = 40

Therefore, the two data sets can be described as having the same range of 40.

Answer:

552

Step-by-step explanation:

Answer:

V = 552 mm^3

Step-by-step explanation:

To find the volume of a prism, you multiply the base and the height. We can write an equation to model the situation:

V = Bh

Where V is the volume, B is the base, and h is the height.

We can substitute the values we have:

V = 92 x 6

V = 552 mm^3

Answer:

Correct Median:

9, 3, 6, 1, 4 (median = 4)

1, 6, 9 (median = 6)

​4. 9, 11, 13, 16, 20 (median = 12)

Incorrect Median:

2. 7.9, 11, 14, 76 (median = 76)

43, 46, 48, 52 (median = 48)

3, 10, 7 (median = 10)

Answer:

126,300.

Step-by-step explanation:

Answer:

Your answer would be 126,350!

Step-by-step explanation: Since the ones place is directly beside the hundreds place to the right, you would use this number to determine whether you stay or round up. 9 is greater then 5, meaning you round up making the hundreds place a 5. Hope this helps! :)

Answer: 24% of students

Step-by-step explanation:

6 students divided by 25 total students = 0.24. You would multiply 0.24 by 100 or move the decimal two places to the right to get the percentage. In this case, the percentage would be 24%. 24% of students do not play spring sports.

[tex]6/25 = 0.24 *100 = 24 percent[/tex]
