Answer:

Step-by-step explanation:

Given that sample size is 130 >30.  Also by central limit theorem, we know that mean (here proportion) of all means of different samples would tend to become normal with mean = average of all means(here proportions)

Hence we can assume normality assumptions here.

Proportion sample given = 92/130 = 0.7077

The mean proportion of different samples for large sample size will follow normal with mean = sample proportion and std error = square root of p(1-p)/n

Hence mean proportion p= 0.7077

q = 1-p =0.2923

Std error = 0.0399

For 95% confidence interval we find that z critical for 95% two tailed is 1,.96

Hence margin of error = + or - 1.96(std error)

= 0.0782

Confidence interval = (p-margin of error, p+margin of error)

= (0.7077-0.0782,0.7077+0.0782)

=(0.6295, 0.7859)

We are 95% confident that average of sample proportions of different samples would lie within these values in the interval for large sample sizes.

Answer:

$34,666.67

Step-by-step explanation:

Step 1: Calculate the interest for 60 days.

(40000*60/360 )* 0.10 = $666.67

Step 2: Amount = Principal + Interest = $40,000 + 666.67 = $40,666.67

Step 3 : After 60 days, he paid $6000.

Remaining balance of the first payment = 40666.67 - 6000 = $34,666.67

Answer:

stem and leaf plot

Step-by-step explanation:

Final answer:

A histogram is the best choice for displaying a set of data with a wide range to find measures of central tendency, as it effectively groups continuous data into frequency bins.

Explanation:

To display a set of data with a wide range, particularly when looking to find measures of central tendency, a histogram is typically the best choice. A histogram allows you to see the data's distribution by grouping data into 'bins' of equal width. Unlike a bar graph, which is more suitable for discrete categories, a histogram's contiguous rectangles make it ideal for showing the frequency of continuous data. Each bar on the histogram represents the frequency of data within a particular interval, giving an immediate visual summary of the data. This makes it easier to estimate the measures of central tendency such as the mean, median, and mode.

A stem-and-leaf plot could also be useful for smaller data sets, as it displays all data values which assist in identifying the central tendency measures directly. However, for larger and continuous data sets, the histogram is more efficient. A frequency table is another option for displaying the frequency of data grouped into ranges, making it possible to calculate the central tendency measures.

I think 81 is composite and is 9 squared. 81 = 1 x 81, 3 x 27, or 9 x 9. Factors of 81: 1, 3, 9, 27, 81. Prime factorization: 81 = 3 x 3 x 3 x 3 which can also be written 3⁴. Since √81 = 9, a whole number, 81 is a perfect square. Even though it has other factors, the only multiplication fact we use is 9 x 9 = 81.

$4.50 because 3 were free wich means 9 cost money 9*0.50=4.5

The cost of 12 candy bars with a 'buy 3 get 1 free' offer is $4.50.

To calculate the cost of 12 candy bars under the 'buy 3 get 1 free' deal, we need to divide the 12 by the group size, which is 4 (3 that you pay for + 1 that you get for free). This results in 3 groups. Since you only pay for 3 candy bars in each group, each group will cost you $0.50 x 3 = $1.50. So, the total cost for 12 candy bars is $1.50 x 3 = $4.50.

Trinda needs 100 or greater

To find the minimum score Trinda can make on the final exam to pass the course with an average of 80 or higher, we set up an inequality and solve for the minimum score.

To find the minimum score Trinda can make on the final exam to pass the course with an average of 80 or higher, we can set up an inequality. Let's represent the minimum score as x. The average of Trinda's algebra tests scores is given by: (72 + 67 + 82 + 79 + x) / 5. To pass the course with an average of 80 or higher, the inequality would be: (72 + 67 + 82 + 79 + x) / 5 ≥ 80.

To solve this inequality, we need to multiply both sides by 5 to eliminate the denominator: 72 + 67 + 82 + 79 + x ≥ 80 * 5. Simplifying this, we get: 300 + x ≥ 400. To isolate x, we subtract 300 from both sides: x ≥ 100.

Therefore, Trinda needs to score a minimum of 100 on her final exam to pass the course with an average of 80 or higher.

The number to correctly fill in the blank in the equation 3 • 1/3 is 1. This is because multiplying 3 by 1/3 is the same as dividing 3 by 3, which equals 1.

In the given equation 3 • 1/3 = ____, you are asked to fill in the blank to make the equation true. Remember that '•' is a symbol representing multiplication. When you multiply 3 by 1/3, we are essentially dividing 3 by 3. This operation results in 1, so to make the equation true, you would insert '1' into the blank. Thus, the full equation, solved, is '3 • 1/3 = 1'.

To fill in the blank and make the equation true, we need to multiply 3 by 1/3. The product of 3 and 1/3 is 1. Therefore, 3 * 1/3 = 1.

Answer:

4c² + 7c - 5 = 0

c = (-7 ± √(7² - 4(4)(-5)))/(2(4))

= (-7 ± √(49 + 80))/8

= (-7 ± √129)/8

Final answer:

To solve the equation 4c^2 + 7c - 5 = 0, use the quadratic formula to find the roots by substituting the values of a, b, and c into the formula and solving.

Explanation:

The equation is 4c2 + 7c - 5 = 0.

Using the quadratic formula:

Identify a = 4, b = 7, and c = -5.

Substitute into the formula: c = (-b ± √(b2 - 4ac)) / 2a.

Calculate the roots by plugging in the values: c = (-7 ± √(72 - 4*4*(-5))) / 2*4.

c = 0.66

First, identify the ten-thousands digit.

4 - ones digit

3 - tens digit

8 - hundreds digit

5 - thousands digit

6 - ten-thousands digit.

The 6 is the ten-thousands digit.

First, make every digit to the right of the ten-thousands digit zero.

You get 60,000.

Now check the digit just to the right of the ten-thousands digit. If it is zero through 4, you are done. If it is 5 through 9, the 6 goes up 1 to 7. The digit to the right of the ten-thousands digit is 5, so the 6 goes up 1 to 7, and the answer is 70,000.
