A density curve for all the possible weights between 0 pounds and 10 pounds is in the shape of a rectangle. What is the height of the rectangle in this density curve? O A. 0.01 OB. 0.001 O c. 0.1 O D. 0.0001 SUBMIT
Answers
Answer:
0.1
Step-by-step explanation:
For a density curve, total area = 1
Probability lies in between 0 and 1
The Area of rectangle :
Area = Length * width
Length = 0 - 10 = 10
Area = 1
Hence,
Area = Length * width
1 = 10 * w
1 = 10w
w = 1 /10
w = 0.1
Gary went to dinner with his friends. The total bill comes to $135.00 before tax. He wants to leave a 15% tip before tax. He also must pay an 8% tax on the bill. How much does Gary spend in total?
No links or I will report!
Answers
Answer:
Gary spends a total of $166.05
Step-by-step explanation:
15% tip: would be 15% of 135, so 0.15 times 135, which would be $20.25 for the tip before tax
8% tax: would be 8% of 135, so 0.08 times 135, which would be $10.8
Then we add $20.25+$10.8+$135= $166.05

Step-by-step explanation:
Trigonometric functions and quadrants:
In x is in the first quadrant, cos(x) > 0 and sin(x) > 0.
In x is in the second quadrant, cos(x) < 0 and sin(x) > 0.
In x is in the third quadrant, cos(x) < 0 and sin(x) < 0.
In x is in the fourth quadrant, cos(x) > 0 and sin(x) < 0.

Answer:
1/5 = 20% = 0.201/4 = 25% = 0.251/2 = 50% = 0.52/3 = 66.6...% = 0.6...Step-by-step explanation:
The symbol % is interchangeable with /100. That is 25% = 25/100. One percent is one hundredth, so the decimal equivalent can be found by writing the percentage number in the hundredths place of a decimal number.
25% = 25/100 = 0.25 = 25 hundredths
The fractions can be converted to percentages by any of ...
multiply by 100%: 1/5 × 100% = (100/5)% = 20%
multiply by a value that makes the denominator 100: 1/5 × 20/20 = 20/100
divide the numerator by the denominator to get the decimal, then convert
1/5 = 0.20 = 20%
__
Additional comment
You will notice that multiplying by 100% is the same as moving the decimal point right 2 places and adding a % symbol. Similarly, dividing by 100% will convert a percentage back to a decimal. It has the effect of removing the % symbol and shifting the decimal point left 2 places.

the total mass of 6 rugby players is 540kg and the mean mass of 14 ballet dancers is 40kg. Find the mean mass of the group of 20 rugby players and ballet dancers
Answers
Answer:
Mean mass of 20 rugby player = 55
Step-by-step explanation:
Given:
Mass of 6 rugby players = 540 kg
Mean mass of 14 ballet dancer = 40 kg
Find:
Mean mass of 20 rugby player
Computation:
Total mass of ballet dancer = 14 x 40
Total mass of ballet dancer = 560 kg
Total mean mass of 20 rugby player = [540 + 560] / [6 + 14]
Mean mass of 20 rugby player = 1100 / 20
Mean mass of 20 rugby player = 55

Find the area of the regular polygon. Round to the nearest tenth.
Answers
Answer:
3462.8 squared unit
Step-by-step explanation:
Applying,
A = nh²tan(360/n)......... equation 1
Where A = area of the regular polygon, n = number of sides of the polygon, h = length of the apothem.
From the question,
Give; n = 5 sides, h = 15
Substitute these values into equation 1
A = 5×15²×tan(360/5)
A = 1125×tan72
A = 1125×3.078
A = 3462.75
A = 3462.8 squared unit
Statisticians prefer large samples. Describe briefly the effect of increasing the size of a sample (or the number of subjects in an experiment) on each of the following:
1. Increases
2. Decreases
3. Unaffected
A. The margin of error of a 95% confidence interval.
B. The P-value of a test, when H0 is false and all facts about the population remain unchanged as n increases.
C. The power of a fixed level test when the alternative hypothesis, and all facts about the population remain unchanged.
Answers
Answer:
Margin of Error decreases
Pvalue decreases
Power increases
Step-by-step explanation:
The margin of error decreases as sample size increases given the same level of confidence, hence, the interval gets narrower.
The margin of error = (Zcritical * σ/√n) ; where, n is the denominator, as the denomination increases, the obtained value will decrease, hence, the margin of error.
When we have a false H0, then we expect a statistical result which will reject H0, with all facts remaining unchanged , increase in sample size n, will lead to decrease in Pvalue, because a lower P value increases the significance of statistical test needed to reject H0.
The power of a fixed level test when the null hypothesis is true, higher power is required to reject the null , increasing n will increase the probability of rejecting H0, by increasing the power of a fixed level test.

Step-by-step explanation:
3x² - 5x - 12 = 0
Method 1: Factoring
3x² + 4x - 9x - 12 = 0
(3x² + 4x) + (- 9x - 12) = 0
x(3x + 4) - 3(3x + 4) = 0
(x - 3)(3x + 4) = 0
Two separate equations
x - 3 = 0
3x + 4 = 0
x - 3 = 0
x - 3 + 3 = 0 + 3
3x + 4 = 0
3x + 4 - 4 = 0 - 4
