The sine of Z is 0.834.
How to calculate sine of an angle?Assume that "α" is the angle in a right triangle XYZ. The sine formula is then given as Sin = Opposite side/ Hypotenuse.
Using the Pythagorean theorem, we can find the length of side Y:
Y² = X² + Z²
Y² = 7² + ( √(21) )²
Y² = 49 + 21
Y² = 70
Y = √(70)
Now we can use the definition of sine:
sin(Z) = opposite/hypotenuse
sin(Z) = X / Y
sin(Z) = 7 / √(70)
sin(Z) = (7 / 10) √(70)
So the sine of Z is (7 / 10) √(70), or approximately 0.834.

A manufacturer working at the 430 gram setting, and a 21 bag sample had a mean of 421 grams with a standard deviation of 15. The p-value of test statistic is 0.0074.
To test whether the bag filling machine works correctly at the 430 gram setting, we can conduct a one-sample t-test. The null hypothesis is that the true mean weight of the bags filled by the machine is equal to 430 grams, and the alternative hypothesis is that the true mean weight is less than 430 grams.
The test statistic is calculated as:
t = (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size))
Plugging in the values given in the problem, we get:
t = (421 - 430) / (15 / sqrt(21)) = -2.77
The degrees of freedom for the t-distribution are n - 1 = 20.
Using a t-table or calculator, we can find the p-value associated with a t-score of -2.77 and 20 degrees of freedom. The p-value turns out to be 0.0074 (rounded to four decimal places).
Since the p-value is less than the level of significance of 0.1, we can reject the null hypothesis and conclude that the bag filling machine is underfilling the bags at the 430 gram setting.

m varies directly as n, and m=14 when n=7
a) write an equation that relates m and n
b) find m when n = 16
c) find n when m = 30
Answer:
see explanation
Step-by-step explanation:
(a)
given m varies directly as n then the equation relating them is
m = kn ← k is the constant of variation
to find k use the condition m = 14 when n = 7
14 = 7k ( divide both sides by 7 )
2 = k
m = 2n ← equation of variation
(b)
when n = 16 , then
m = 2 × 16 = 32
(c)
when m = 30 , then
30 = 2n ( divide both sides by 2 )
15 = n
Use a graphing calculator to find an equation of the line of best fit for the data. Round the slope to the nearest tenth and the y
-intercept to the nearest integer.
For the given table -
The equation for line of best fit is Y = -1.000 · X + 11.25.
The correlation coefficient is -0.443533.
x and y have negative and strong correlation.
What is correlation coefficient?
A statistical concept known as the correlation coefficient aids in establishing a relationship between expected and actual values gained through statistical experimentation. The estimated correlation coefficient's value explains how well the expected and actual values match.
The table of data is given.
The formula for equation of the line of best fit is -
Y = b·X + a
On adding the values in a graphing calculator the equation is -
Y = -1.000 · X + 11.25
Here, the slope is -1 and y-intercept is 11.25.
The formula for correlation coefficient is -
r = [n(∑xy) - (∑x)(∑y)] / [n∑x² - (∑x²)][n∑y² - (∑y²)]
n = Number of values or elements
∑x = Sum of 1st values list
∑y = Sum of 2nd values list
∑xy = Sum of the product of 1st and 2nd values
∑x² = Sum of squares of 1st values
∑y² = Sum of squares of 2nd values
For the given table the values are -
n = 8, ∑x = 68, ∑y = 22, ∑xy = 145, ∑x² = 620, ∑y² = 274
Plug in all the values in the equation -
r = [8(145) - (68)(22)] / [8(620) - (620)][8(274) - (274)]
r = -0.443533
When the values of two variables grow while one variable's values fall. The correlation coefficient would be negative in that situation.
The weak and adverse association is indicated by the coefficient's negative value. And if "r" keeps moving in the direction of -1, the relationship is moving in the negative direction.
Therefore, the equation is Y = -1.000 · X + 11.25 and r value is -0.443533.

what is the probability that the sample mean annual insurance cost is greater than $620? show your work.
The probability of the sample mean annual insurance cost being greater than $620 is very low, that is 0.00317% which indicating that it is unlikely to happen by chance.
Probability is a branch of mathematics that deals with the likelihood of an event happening. It is used in various fields, such as insurance, finance, and science.
To calculate the probability, we need to use the central limit theorem, which states that the distribution of sample means of a population approaches a normal distribution as the sample size increases. We also need to know the mean and standard deviation of the population.
Assuming that the population is normally distributed, we can use the following formula to calculate the probability:
z = (x - μ) / (σ / √(n))
where z is the z-score, x is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.
In this case, we don't know the population mean and standard deviation, but we can use the sample mean and standard deviation as estimates. Let's say we have a sample of 100 insurance costs with a mean of $600 and a standard deviation of $50.
Now, we can calculate the z-score:
z = (620 - 600) / (50 / √(100)) = 4
The z-score of 4 indicates that the sample mean of $620 is 4 standard deviations away from the mean of $600. We can use a standard normal distribution table or a calculator to find the probability of getting a z-score of 4 or higher. The probability is very small, approximately 0.0000317 or 0.00317%.

= 61/10
Answer:
Simplified form: 6 1/10
Improper form: 61/10
Step-by-step explanation:
5 3/5 + 1/2
= 28/5 + 1/2
Then, you multiply both fractions so that the denominator is the same number. In this case, multiply the fraction (numerator and denominator) on the left by 2 and on the right by 5.
= 56/10 + 5/10
This way, you can add the numbers because they have the same denominator.
=61/10
Mr. Stanley owns a farm measuring 24m long and 40m wide. If he wants to plant in squares, what is the largest sized square he can use?
The largest square that Mr. Stanley can use to plant in his farm is a square with a side length of 8 meters.
To find the greatest common factor of 24 and 40, we can list the factors of both numbers and find the highest factor that they have in common:
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40
The highest factor that 24 and 40 have in common is 8.
Factors are numbers that can be multiplied together to get a given number. For example, the factors of 6 are 1, 2, 3, and 6 because 1 x 6 = 6 and 2 x 3 = 6. Factors can be prime or composite. Prime factors are those that are only divisible by 1 and themselves. Composite factors are those that have more than two factors.
Factors are important in math because they can be used to simplify fractions, find common denominators, and solve equations. They also play a crucial role in number theory and cryptography, where they are used to encrypt and decrypt messages. 150 is a composite number, which means it has factors other than 1 and itself. The factors of 150 are 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, and 150. To find these factors, you can divide 150 by each number smaller than it and see if the remainder is 0.

Give the starting value a, the growth factor b, and the growth rate r if q = abt = a(1 r)t. write r as a percent. q = 79 (1.002) superscript t a. a. a = 79 b = 1.002 r = 0.2% b. a = 79.158 b = 1.002 r = 0.002% c. a = 79 b = 0.002 r = 1.002% d. a = 79.158 b = 0.002 r = 0.2%
r as a percent is a) a = 79, b = 1.002, and r = 0.2%.
The formula given, q = abt = a(1+r)t, represents exponential growth, where a is the starting value, b is the growth factor, r is the growth rate, t is the time period, and q is the final value after t periods.
Given q = 79(1.002)^t, we can see that:
a = 79 (the starting value)
b = 1.002 (the growth factor)
r = 0.2% or 0.002 (the growth rate, expressed as a decimal)
So, the correct answer is a) a = 79, b = 1.002, and r = 0.2%.

PLEASE HELP IS DUE TOMORROW:The average American throws away 2.5 pounds of empty cans a month (mostly during the winter months). At this rate, how many years will it take the average American to throw away a ton of empty cans? (Show work please)
1 ton = 2000 pounds
2000/2.5 = 800 months
800/12 = ~66.67 years
Answer:
your answer would be 66.6: do the math: 2.5 a month times 12 months in a year=30. 1 ton =2000 pounds. 2000 divided by 2.5 =800. 800 divided by 12=66.6
