Answer:

The piece left over is 10 cm long

Step-by-step explanation:

1 metre = 100 cm

Each piece = 30 cm long

Number of piece = 3

30 × 3 = 90

100 - 90 = 10 cm

Therefore, the piece left over is 10 cm long

The probability that none of the three products is successful is calculated by multiplying the probabilities of failure (1 - probability of success) for each product. Assuming independence, the calculation is as follows:

Product 1 failure probability: 1 - 1/9 = 8/9
Product 2 failure probability: 1 - 2/3 = 1/3
Product 3 failure probability: 1 - 1/5 = 4/5

Probability of all products failing: (8/9) × (1/3) × (4/5) = 32/135


Since the probabilities of success for each product are independent, we can simply multiply the probabilities of failure for each product to find the overall probability of none of the products being successful. This is a basic principle of probability when dealing with independent events.


The probability that none of the three products is successful in the market is 32/135.

The solution is: 5 in hours did Ben work that Saturday​.

The number of hours that Ben worked at the restaurant can be calculated by the expression, Xpm - Xam.

The number of hours that Ben worked can be represented as:

= Time he finished working - Time he started working

= X pm - X am

If for instance, he started work at 7 am and finished at 12 pm, he would have worked:

= 12 - 7

= 5 hours

The expression that shows the length of time he worked can therefore be concluded to Xpm - Xam.

The Decimal 0.612 and the 12 is repeating as a fraction is 20.346/33.

Step 1: Let x = 0.612

Step 2: Multiply both sides by 1000 to remove the decimal point: 1000x = 612

Step 3: Since the 12 is repeating, we can subtract the non-repeating part from the repeating part to get 12 - 0 = 12. Then we can write the repeating part as a fraction with a denominator of 99 (which is one less than 100, the number of repeating digits). So we have: 0.12 = 12/99

Step 4: Rewrite the equation from step 2 using the value from step 3: 1000x = 612 + 12/99

Step 5: Simplify the right-hand side: 1000x = 61038/99

Step 6: Divide both sides by 1000 to solve for x: x = 61.038/99

Step 7: Simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 3: x = 20.346/33

Therefore, the decimal 0.612 and the 12 is repeating as a fraction is 20.346/33.

From the hypothesis test conducted, the calculated t-statistic of -3.57 is less than the lower critical t-value of -2.064. This tells us that the observed sample mean of 87% is significantly different from the claimed population mean of 92% at the 0.05 significance level. Therefore, the null hypothesis can be rejected and conclusions can be made that that there is enough evidence to suggest that the average grade of the students in the Algebra 2 class this year is not equal to the average grade of the same students in the Algebra 1 class two years ago.

To determine whether there is enough evidence to reject the teacher's claim, we can conduct a hypothesis test. A one-sample t-test will be us to compare sample mean.

Here are the sample statistics:

Sample size (n) = 25

Sample mean (X) = 87%

Sample standard deviation (s) = 7%

A significance level (α) of 0.05, wil be used

We first calculate the t-statistic, with  (X - μ) / (s/√n),

t = (87 - 92) / (7/√25) = -5 / (7/5) = -3.57

Then, we check this value against the critical t-value for a two-tailed test with 24 degrees of freedom (n-1), and α = 0.05.

The critical t-values for a two-tailed test at α = 0.05 and df = 24 are approximately -2.064 and +2.064.

-3.57 t-test is less than the lower critical t-value of -2.064. This means that the observed sample mean of 87% is significantly different from the claimed population mean of 92% at the 0.05 significance level.

The surface area of the prism is 520 in².

The area of the prism is 750 in³.

We have,

The given figure is a rectangular prism.

The surface area can be calculated by adding all the areas of the surfaces.

Now,

There are two types of surfaces.

Top and bottom surfaces and the side surfaces

So,

Top surface = Bottom surface

Area = 2 x (8 x 7(1/2)) = 8 x 15 = 120

Side surface.

Area = 4 x (8 x 12(1/2)) = 4 x (8 x 25/2) = 4 x 4 x 25 = 16 x 25 = 400

The surface area.

= 120 + 400

= 520 in²

And,

The area of the prism.

= 8 x 7(1/2) x 12(1/2)

= 8 x 15/2 x 25/2

= 2 x 15 x 25
= 30 x 25

= 750 in³

Thus,

The surface area of the prism is 520 in².

To detect the y-intercept of a line in a graph, you need to find the point where the line intersects the y-axis. In other words, it's the point where the value of x is zero.

To find the y-intercept of a line on a graph:

If the equation of the line is in slope-intercept form, y = mx + b, where m is the slope of the line and b is the y-intercept, then the value of b is the y-coordinate of the point where the line intersects the y-axis.

In the given graph line is paasing through origin (0, 0).

Thus, the value of y where the value of x will be zero is zero.

You would divide 244.40 by 26%

You would get  63.544.... Now times the 63.544 to the remainder of the 26 from 100...which is 74.  63.544 times 74 equals 4702.256.

Now add the 244.40 to that and u get the answer of 4946.656.

Answer:

Good Luck

Step-by-step explanation:

Let the regular price be "x".

According to the problem, the sofa is being sold for 26% of the regular price, which means the sale price is:

Sale price = 0.26x

The problem also states that the sale price is $244.40, so we can write:

0.26x = 244.40

To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides by 0.26:

x = 244.40 ÷ 0.26

x = 940

Therefore, the regular price of the sofa is $940.

Each line in every set of lines of the same color intersects with each line in two other sets. Because of that fact, there's a segment formed on each line in every set.

In order to determine the difference between the largest and smallest 4-digit in which the values do not change when their digits are reversed, we can start with;

This problem falls under number theory and we can apply some insight here;

In this case, the smallest value will be 1000 while the largest will be 9999

We can add 1 from 1000 till we reach 9999. For each number, we compare it with its reversed form. If they are equal, we store that number as a candidate for the smallest and largest numbers.

After checking all the numbers, we find that the smallest and largest numbers that meet the given criterion are:

Smallest number: 1001 (remains the same when digits are reversed)

Largest number: 9999 (remains the same when digits are reversed)

Now, we can calculate the difference between the smallest and largest numbers:

Difference = Largest number - Smallest number

Difference = 9999 - 1001

Difference = 8998

Therefore, the difference between the smallest and largest 4-digit numbers that do not change when their digits are reversed is 8998.

Therefore, the sample variance is approximately 65 using 95% confidence interval.

To find the sample variance, we need to use the formula for the confidence interval of the mean:

X ± tα/2 (s/√n)

Where:

X is the sample mean

tα/2 is the critical value for the t-distribution at the desired confidence level (with n-1 degrees of freedom)

s is the sample standard deviation

n is the sample size

From the given information, we know that the sample size n = 13, and the confidence interval is (3.5990, 19.0736) with a 95% confidence level. This means that the critical value for the t-distribution at α/2 = 0.025 and 11 degrees of freedom is approximately 2.201.

Using the formula for the confidence interval and the upper and lower bounds of the interval, we can solve for s:

19.0736 = X + 2.201(s/√13)

3.5990 = X - 2.201(s/√13)

Adding the two equations gives:

22.6726 = 2X

Therefore, X = 11.3363

Substituting this value of X into one of the original equations gives:

19.0736 = 11.3363 + 2.201(s/√13)

Solving for s, we get:
