Step-by-step explanation:
y = 3x + 40 (David)
y = 6x + 25 (Perla)
since both equal 'y' we can set the expressions equal and solve for 'x'
3x + 40 = 6x + 25
subtract 3x from each side to get:
40 = 3x + 25
subtract 25 from each side to get:
15 = 3x
15/3 = x
5 = x

Given:
The numbers are [tex]-5,0,6,-3.5,-1\dfrac{2}{3}[/tex].
To find:
The number line one which each of the given number is plotted correctly.
Solution:
The given numbers are [tex]-5,0,6,-3.5,-1\dfrac{2}{3}[/tex].
To plot [tex]-5,0,6[/tex], we need to make dots at [tex]-5,0,6[/tex] respectively.
To plot [tex]-3.5[/tex], we need to make a dot in the mid of -4 and -3.
To plot [tex]-1\dfrac{2}{3}[/tex], we need to make a dot between -2 and -1. That point divides the segment between -2 and -1 in 1:2
In option A, -5 is not plotted correctly. So, option A is incorrect.
In option B, -3.5 is not plotted correctly and [tex]-1\dfrac{2}{3}[/tex] is not plotted. So, option B is incorrect.
In option C, all the points are plotted correctly. So, option C is correct.
In option D, [tex]-1\dfrac{2}{3}[/tex] is not plotted correclty. So, option D is incorrect.
Therefore, the correct option is C.
If 4 television weigh 160 pounds , How much do 5 of those television weigh.
Must show your work
Answer:
Step-by-step explanation:
640
Answer:
200 pounds
Step-by-step explanation:
We can write a proportion to represent the problem. Let's take x as the weight of 5 televisions. If we know that 4 televisions weigh 160 pounds we can write: 4/160. Then, 5 televisions will weigh x pounds which is 5/x. Now, we can set up a proportion: 4/160 = 5/x
Cross multiply to get: 4x = 800
Isolate x: x = 800/4
Solve: x = 200
200 pounds

Answer:
the first one
Step-by-step explanation:
The problem says that the plot must have a maximum of 44, which means the most right dot must be on the 44 mark. All the graphs fit this requirement (the dashes are in increments of 2) The problem says that it must have an upper quartile of 39, which means the line closest to the maximum dot must be on the 39 mark. Graphs 2 and 3 do not meet this requirement, so they are eliminated. The last requirement is the median of 25. The median is represented by the middle line in the middle of the boxes. Graph 4 does not fit this requirement, so it is eliminated. Thus, only the first graph follows all 3 requirements.
Researchers investigating a new drug selected a random sample of 200 people who are taking the drug. Of those selected, 76 indicated they were experiencing side effects from the drug. If 5,000 people took the drug, which of the following is closest to the interval estimate of the number of people who would indicate they were experiencing side effects from the drug at a 95 percent level of confidence?
a. (0.313,0.447)
b. (0.324, 0.436)
c. (65,87)
d. (1565, 2235)
e. (1620, 2180)
Answer:
a. (0.313,0.447)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
Researchers investigating a new drug selected a random sample of 200 people who are taking the drug. Of those selected, 76 indicated they were experiencing side effects from the drug.
This means that [tex]n = 200, \pi = \frac{76}{200} = 0.38[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.38 - 1.96\sqrt{\frac{0.38*0.62}{200}} = 0.313[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.38 + 1.96\sqrt{\frac{0.38*0.62}{200}} = 0.447[/tex]
The correct answer is given by option A.

Penny works 44 hours at an hourly rate of $8.50. She was paid time and a half for the overtime of 4 hours. What were her total wages?
Answer:
Time and a half pay is 50% more than an employee's regular rate of pay. For every hour of overtime an employee works, you must give them their regular rate of pay plus half of that. To calculate an employee's overtime rate of pay, multiply their regular rate by 1.5.

r = - 0.98754
Answer:
Slope = - 0.7120
SE = 1.295
Step-by-step explanation:
Given the data:
0 | 33.3
0 | 31.0
3 | 29.8
3 | 27.8
6 | 28.0
6 | 29.0
10 | 25.5
10 | 23.8
20 | 18.3
20 | 15.5
30 | 11.7
Using the relation to Obtian the slope :
Slope, b = r(Sy/Sx)
r = correlation Coefficient ; Sy = standard deviation of Y - values ; Sx = standard deviation of X-values
r = - 0.98754
Slope, b = - 0.98754(7.8471 / 10.884) = - 0.7120
SE = √SSresidual / df
df = n - 2 = 12 - 2 = 10
SSresidual = 16.7812
SE = √(16.7812/ 10)
SE = 1.295
A recent math test results show a mean of 75 and a standard deviation of 3. A random test is chosen with a raw score of 86. Which of the following tests scores is better than what percentage of all scores?
TEST 1: x=65, μ=70, σ=3
TEST 2: x=80, μ=50, σ=10
A) Test 1 has the highest z-score
B) Test 2 has the highest z-score
C) Neither, the original test has a z-score 3.67 which is the highest z-score.
Answer:
c
Step-by-step explanation:
The test which scores are better than the percentage of all scores will be tested 2 and the percentage is 3. Hence, option B is correct.
What is Normal distribution?A probability distribution that is symmetric around the mean and demonstrates that data close to the mean are more likely to occur than data distant from the mean.
As per the given information in the question,
1.
x = 65
Mean, μ = 70
Standard deviation, σ = 3
Use the equation given below to find the percentage,
Z = (x - Mean)/Standard deviation,
Z = (64 - 70)/3
= -6/3
Z = -2
2.
x = 80
Mean, μ = 50
Standard deviation, σ = 10
Use the equation given below to find the percentage,
Z = (x - Mean)/Standard deviation,
Z = (80 - 50)/10
= 30/10
Z = 3
Compare the values obtained, and it is clear that Test 2 got height score.

Mrs. Simpson is frosting circular sugar cookies. Each cookie is 6 cm in diameter. About how many square centimeters will she need to frost each cookie?
Answer:
9 pi
Step-by-step explanation:
Answer:
28.274 cm^2 (remember units are important)
Step-by-step explanation:
The answer is the area of the cookie. The area of the cookie (neglecting its thickness) is:
A = pi(r^2)
here the radius is 1/2 the diameter of 6 cm:
A = 3.14159 * 3^2 or A = 3.14159* 9 = 28.274 cm^2

Answer:
∠2 = 41°
Step-by-step explanation:
∠2 + 49° + 90° = 180°
∠2 + 139° = 180°
∠2 = 180° - 139°
∠2 = 41°
Answer:
[tex] \displaystyle \angle2 = \bigg[{41}^{ \circ} \bigg][/tex]
Step-by-step explanation:
we are given a right angle triangle
we want to figure out the missing interior angle
recall that,
one of angle measure of a right angle triangle is 90° interior angles of a triangle add up to 180°thus our equation is
[tex] \displaystyle {49}^{ \circ} + \angle2 + {90}^{ \circ} = {180}^{ \circ} [/tex]
simplify addition:
[tex] \displaystyle \angle2 + {139}^{ \circ} = {180}^{ \circ} [/tex]
cancel 139° from both sides:
[tex] \displaystyle \angle2 = {41}^{ \circ} [/tex]
hence,
the measure of the missing angle is 41°

Find the argument of the complex number z=1+iv3
Given:
The complex number is:
[tex]z=1+i\sqrt{3}[/tex]
To find:
The argument of the given complex number.
Solution:
If a complex number is [tex]z=x+iy[/tex], then the argument of the complex number is:
[tex]\theta=\tan^{-1}\dfrac{y}{x}[/tex]
We have,
[tex]z=1+i\sqrt{3}[/tex]
Here, [tex]x=1[/tex] and [tex]y=\sqrt{3}[/tex]. So, the argument of the given complex number is:
[tex]\theta =\tan^{-1}\dfrac{\sqrt{3}}{1}[/tex]
[tex]\theta =\tan^{-1}\sqrt{3}[/tex]
[tex]\theta =\tan^{-1}\left(\tan \dfrac{\pi}{3}\right)[/tex]
[tex]\theta =\dfrac{\pi}{3}[/tex]
Therefore, the argument of the given complex number is [tex]\theta =\dfrac{\pi}{3}[/tex].
