Explain why the equation is not linear.
5/x - y = 1
A. x Should be an exponent.
B. The x variable appears in the denominator.
C. The coefficient of both variables must be equal.
D. There should be an exponent of 2 on either x or y.
Answer:
B. The x variable appears in the denominator.
Step-by-step explanation:
Given
[tex]\frac{5}{x} - y = 1[/tex]
Required
What makes it not linear
First, make y the subject
[tex]y = \frac{5}{x}+1[/tex]
A linear equation is represented as:
[tex]y = mx + b[/tex]
Notice that the exponent of x in the general form is: 1
This means that x has to appear as a numerator
In [tex]y = \frac{5}{x}+1[/tex], the exponent of x is -1
This means that x has to appear as a denominator
Hence, (b) is true

Find RS. Explain your reasoning.
6x + 5=9x - 4
Answer:
x = 3
Step-by-step explanation:
Given the equation :
6x + 5=9x - 4
Collect like terms :
6x - 9x = - 4 - 5
-3x = - 9
Divide both sides by - 3
-3x / - 3 = - 9 / - 3
x = 3
Hence, x = 3

What is the measure of Angle X? I'm not sure if its B.
Answer:
the sum of all angles in a triangle is 180°.
the two triangles got the same angles I suppose
180-85-25 = 70
70° is the answer
Answer:
X = 70
Step-by-step explanation:
Since ABC is similar to XYZ
Angle A is equal to angle X
We can find angle A since the sum of the angles of a triangle is 180
A + B+C = 180
A + 85+25 = 180
A + 110 =180
A = 180-110
A = 70
X = 70

Whats the absoulute value of -3
Answer:
3
Step-by-step explanation:
The absolute value of a number is that number's distance from 0.
Therefore, |-3| = 3.
Answer:
the absolute value is the non-negative value of a real number without regard for its sign. so the absoulute value of -3 is 3 you just change the negative sign to a positive.
Step-by-step explanation:
3 is the answer
A 39-foot piece of string (hypotenuse) is stretched from the top of a 18-foot flagpole to the ground. How far is the base of the flagpole from the end of the piece of string? Round your answer to the nearest tenth ( decimal places). (Hint: Draw a picture on your own paper to visualize the problem)
9514 1404 393
Answer:
34.6 ft
Step-by-step explanation:
The distance can be found using the Pythagorean theorem. Where a, b, c are the sides of a right triangle with c as the hypotenuse, it tells you ...
a² + b² = c²
a = √(c² -b²)
base-to-string = √(39² -18²) = √1197 ≈ 34.598
The distance from the base of the pole to the end of the string is about 34.6 feet.
If MNLP, then 2 _____ 3. Choose the relationship symbol to make a true statement. < > =
Answer:
The answer is > (greater than)
Step-by-step explanation:
It is > because if MN is the larger side and the largest angle would be across from the largest side, then that would make the largest angle, angle 2 and that would in turn make 3 the smaller angle. I know this is correct because I got it right.
solve for the missing values in the table below:
Answer:
The answers to your questions are given below.
Step-by-step explanation:
A. Determination of the length.
Length (cm) = 32
Length (m) =?
Length (mm) =?
I. Determination of the length in m.
100 cm = 1 m
Therefore,
32 cm = 32 × 1 m / 100 cm
32 cm = 0.32 m
II. Determination of the length in mm
1 cm = 10 mm
Therefore,
32 cm = 32 cm × 10 mm / 1 cm
32 cm = 320 mm
B. Determination of the height.
Height (m) = 1.58 m
Height (cm) =?
Height (mm) =?
I. Determination of the height in cm.
1 m = 100 cm
Therefore,
1.58 m = 1.58 m × 100 cm / 1 m
1.58 m = 158 cm
II. Determination of the height in mm
1 m = 1000 mm
Therefore,
1.58 m = 1.58 m × 1000 mm / 1 m
1.58 m = 1580 mm
C. Determination of the width.
Width (mm) = 36 mm
Width (m) =?
Width (cm) =?
I. Determination of the width in m.
1000 mm = 1 m
Therefore,
36 mm = 36 mm × 1 m / 1000 mm
36 mm = 0.036 m
II. Determination of the width in cm
10 mm = 1 cm
Therefore,
36 mm = 36 mm × 1 cm / 10 mm
36 mm = 3.6 cm
D. Determination of the length.
Width (mm) = 105 mm
Width (m) =?
Width (cm) =?
I. Determination of the width in m.
1000 mm = 1 m
Therefore,
105 mm = 105 mm × 1 m / 1000 mm
105 mm = 0.105 m
II. Determination of the width in cm
10 mm = 1 cm
Therefore,
105 mm = 105 mm × 1 cm / 10 mm
105 mm = 10.5 cm
E. Determination of the length.
Length (m) = 2 m
Length (cm) =?
Length (mm) =?
I. Determination of the length in cm.
1 m = 100 cm
Therefore,
2 m = 2 m × 100 cm / 1 m
2 m = 200 cm
II. Determination of the length in mm
1 m = 1000 mm
Therefore,
2 m = 2 m × 1000 mm / 1 m
2 m = 2000 mm
Summary:
Item >>>>>>>> m >>>> cm >>>> mm
A. Lenght >>> 0.32 >> 32 >>>> 320
B. Height >>> 1.58 >> 158 >>>> 1580
C. Width >>> 0.036 >> 3.6 >>>> 36
D. Length >> 0.105 >> 10.5 >>> 105
E. Width >>> 2 >>>>>> 200 >>> 2000

Out of 200 people sampled, 52 had kids. Based on this, construct a 99% confidence interval for the true population proportion of people with kids.
Answer:
0.180144 < p < 0.339856
Step-by-step explanation:
According to the Question,
Given That, Out of 200 people sampled, 52 had kids, Thus the proportion of the mean is 52/200 = 0.26⇒ standard error of the sample is square root(0.26 * (1-0.26) / 200) = 0.031
⇒alpha(a) = 1 - 99/100 = 0.01
⇒critical probability(p*) = 1 - a/2 = 0.995
⇒assuming a normal distribution, look for the z-score associated with 0.995 cumulative probability , z-score = 2.576
⇒margin of error(ME) = 2.576 * 0.031 = 0.079856
the confidence interval is 0.26 + or - 0.0798560.180144 < p < 0.339856

In ΔQRS, the measure of ∠S=90°, RQ = 41, QS = 9, and SR = 40. What is the value of the cosine of ∠R to the nearest hundredth?
Answer:
cos R = .98
Step-by-step explanation:
cos R = SR/QR
QR is the hypotenuse of the right triangle. By the Pythagorean theorem
(QR)^2 = (QS)^2 + (SR)^2
= 9^2 + 40^2
= 81 + 1600
= 1681
QR = 41
Cos R = adjacent side/hypotenuse = 40/41 = .98
The value of the cosine of ∠R to the nearest hundreth is 0.98.
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
The sides can also be found using pythagoras theorem. Therefore,
∠S = 90°
RQ = 41
QS = 9
SR = 40
cos R = adjacent / hypotenuse
Therefore,
adjacent side = 40
hypotenuse = 41
cos R = 40 / 41
cos R = 0.97560975609
cos R = 0.98

Exhibit 11-2 We are interested in determining whether the variances of the sales at two music stores (A and B) are equal. A sample of 25 days of sales at store A has a sample standard deviation of 30, while a sample of 16 days of sales from store B has a sample standard deviation of 20. At 95% confidence, the null hypothesis _____. a. should not be rejected b. should be revised c. should be rejected d. None of these answers are correct.
Answer:
Option A , should not be rejected
Step-by-step explanation:
From the question we are told that:
Sample 1 [tex]n=25[/tex]
Standard deviation 1 [tex]\sigma_1=30[/tex]
Sample 2 [tex]n=16[/tex]
Standard deviation 2 [tex]\sigma_2=20[/tex]
Level of confidence [tex]\alpha=95\%=>0.95[/tex]
Generally The Hypothesis are given as
[tex]H_0:\sigma_1^2=\sigma_1^2[/tex]
[tex]H_1:\sigma_1^2\neq \sigma_1^2[/tex]
Generally the equation for test Statistics is mathematically given by
[tex]T=\frac{\sigma_1^2}{\sigma_2^2}[/tex]
[tex]T=\frac{30^2}{20^2}[/tex]
[tex]T=2.25[/tex]
Therefore
Critical Value
[tex]X=(\alpha,df_1)[/tex]
[tex]X'=(\alpha,df_2)[/tex]
Where
[tex]df=n-1[/tex]
Therefore
[tex]X=(0.95,24)[/tex]
[tex]X'=(0.95,15)[/tex]
From Table
[tex]T_{Critical}=T_x,T_{x'}[/tex]
[tex]T_{Critical}=0.41,2.701[/tex]
Therefore
[tex]T_x<T<T_{x'}[/tex]
Hence,We fail to reject the Null Hypothesis [tex]H_0[/tex]
Option A , should not be rejected
