Answer:

When you are graphing inequalities you know if it's an open circle or closed circle because when the dot is closed it means that the inequality includes the number and when it's open it does not include the number in the inequality.

Answer:

The 95% confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt is (45%, 51%). This means that we are 95% sure that the true proportion of all registered voters  who are in favor of raising income taxes to pay down the national debt is between these two values, of 45% and 51%.

Step-by-step explanation:

A confidence interval is the sample proportion plus/minus the margin of error.

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

In this question:

Sample proportion of 48%.

Suppose the agency states the margin of error for 95​% confidence is 3.0​%. Determine and interpret the confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt.

48% - 3% = 45%

48% + 3% = 51%

The 95% confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt is (45%, 51%). This means that we are 95% sure that the true proportion of all registered voters  who are in favor of raising income taxes to pay down the national debt is between these two values, of 45% and 51%.

Answer:

0.9544 = 95.44% probability that the average fill for the 100 drums is between 49.88 and 50.12 gallons.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Suppose the mean fill for the shipment is actually 50 gallons. Standard deviation of 0.6 gallons.

This means that [tex]\mu = 50, \sigma = 0.6[/tex]

Sample of 100:

This means that [tex]n = 100, s = \frac{0.6}{\sqrt{100}} = 0.06[/tex]

What is the probability that the average fill for the 100 drums is between 49.88 and 50.12 gallons?

This is the pvalue of Z when X = 50.12 subtracted by the pvalue of Z when X = 49.88. So

X = 50.12

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{50.12 - 50}{0.06}[/tex]

[tex]Z = 2[/tex]

[tex]Z = 2[/tex] has a pvalue of 0.9772

X = 49.88

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{49.88 - 50}{0.06}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a pvalue of 0.0228

0.9772 - 0.0228 = 0.9544

0.9544 = 95.44% probability that the average fill for the 100 drums is between 49.88 and 50.12 gallons.

Answer:

Work done by the woman is 500 joule per second.

Step-by-step explanation:

Force applied by the woman = 300 Newtons

Total displacement due to force = 100 meters

Work done = Force applied × Displacement due to force

                   = 300 × 100

                   = 30000 Joule

Since, Power = [tex]\frac{\text{Work done}}{\text{Time taken to perform the work}}[/tex]

                      = [tex]\frac{W}{t}[/tex]

                      = [tex]\frac{30000}{60}[/tex]

                      = 500 Joule per second

Therefore, work done by the woman is 500 joule per second.

I'm no math braniac, however, I believe the answers are 2 cups; 2/3 cups, 15/2 cups; 2 1/2 cups, and 2/12 cups; 5/6 cups.

I really hope its correct and good luck on your test!

Answer:

Yes, but a diagonal of the rectangle must be a diameter of the circle.

This is because a rectangle is made up of two right triangles.

Answer:

68.75 feet tall

Step-by-step explanation:

Create a proportion where x is the height of the flagpole

[tex]\frac{x}{50}[/tex] = [tex]\frac{5.5}{4}[/tex]

Cross multiply and solve for x

4x = 275

x = 68.75

So, the flagpole is 68.75 feet tall

The dot plot is missing, so i have attached it.

Answer:

B: there are about 2 more students in each class at Oak Middle School than at Poplar Middle School.

Step-by-step explanation:

From the dot plot attached, we can find the average number of students per class for each school.

For Poplar Middle School;

Total number of students = (20 × 3) + (21 × 5) + (22 × 7) + (23 × 4) + (24 × 1) = 435 students.

There are 20 classes.

Thus;

average number of students per class = 435/20 = 21.75

For Oak Middle School;

Total number of students = (20 × 1) + (21 × 2) + (22 × 2) + (23 × 4) + (24 × 3) + (25 × 2) + (26 × 2) + (27 × 2) + (28 × 1) + (29 × 1) = 483

Average number of students per class ; 483/20 = 24.15

Difference in average = 24.15 - 21.75 = 2.40

This implies that there are about 2 more students in each class at Oak Middle School than at Poplar Middle School.

What is (2x² + 9x + 7) = (x + 1) ?

2x² + 9x + 7 = x + 1

2x² + 9x - x + 7 - 1 = 0

2x² + 8x + 6 = 0

2(x² + 4x + 3) = 0

x² + 4x + 3 = 0

x² + 3x + x + 3 = 0

x( x + 3) + 1(x + 3) = 0

(x + 3)(x + 1) = 0

So, option (D) x + 1 is correct. [Answer]

Answer:

Monday=275

Tuesday=330

thursday=360

Friday=440

Step-by-step explanation:

Add the entire number to itself since its above 100%

then figure out 10% of the number for  monday is 12.5 thats only ten so we gotta figure out 20% so 12.5x2=25

Hence its 125+125+25

250+25

275

Answer:

Step-by-step explanation:

Your calculator or a spreadsheet can help you do this. The rules of exponents apply.

  (10^a)(10^b) = 10^(a+b)

__

(2×10^8)(2×10^-2) = 4×10^6

40×10^5 = 4×10^6

40^6 = 4.096×10^9

400,000 = 4×10^5

1.2×10^9/3×10^2 = 4×10^10   or  1.2×10^9/(3×10^2) = 4×10^6 (see note)

_____

Note: A multiplier that is a power of 10 is one factor of a product. A product does not go into the denominator of a fraction unless it has parentheses around it. a/bc = (a/b)c ≠ a/(bc) (This is a consequence of the Order of Operations.)
