Answer:
6s-54
Step by step: Put the 6 in front of the s and then multiply 6*9. so the answer is 6s-54
The distributive property is used in mathematics to multiply a number by multiple numbers within parentheses. Using it for expression 6(s - 9) gives us 6s - 54.
Explanation:The expression you need to simplify using the distributive property is 6(s - 9). The distributive property is a fundamental property in mathematics that allows you to multiply a singular number by multiple numbers within parentheses.
In case of the expression 6(s - 9), you'll simply need to distribute or multiply the number 6 to each term inside the parentheses.
6 x s and 6 x -9. Performing these will give us 6s - 54.

A distribution of numbers has the following five-number summary:
10.0, 15.0, 30.9, 50.0, 63.7
True or False? These numbers can be used to calculate the standard deviation of the distribution. ...?
Answer:
False
Step-by-step explanation:
A five number summary consists of these five statistics: the minimum value, the first quartile, the median, the third quartile, and the maximum value of a set of numbers
A standard deviation is a measure that is used to quantify the amount of variation or dispersion of a set of data values.
Std deviation is the square root of variance
Variance is the average of squares of deviations of each entry from the mean.
Hence from five point summary, we cannot calculated standard deviation of the distribution

The set of possible rational roots for the polynomial is {±1, ±2, ±4, ±5, ±10, ±20}.
Thus, option (B) is correct.
Given:
[tex]x^3+5x^2-8x-20=0[/tex]
Using Rational Root Theorem
if a rational number p/q is a root of the polynomial, then p is a factor of the constant term, and q is a factor of the leading coefficient.
Here, p= -20 and q= 1.
So, the factors of -20 are:
-20, -10, -5, -4, -2, -1, 1, 2, 4, 5, 10, 20.
The factors of 1 (leading coefficient) are:
-1, 1.
Therefore, the possible rational roots are the combinations of these factors, where the numerator is a factor of -20, and the denominator is a factor of 1.
Combining the factors, the set of possible rational roots:
{±1, ±2, ±4, ±5, ±10, ±20}
Thus, option (B) is correct.

In the week before and the week after a holiday there were 10,000 total deaths and 4968 of them occurred in the week before the holiday.
a) construct a 90% confidence interval estimate of the proportion of deaths in the week before the holiday to the total death in the week before and the week after the holiday
b) based on the result does there appear to be any indication that people can temporarily postpone their death to survive the holiday
The confidence interval is calculated based on the given values and can help determine if deaths are temporarily postponed during holidays.
Explanation:To construct a confidence interval estimate of the proportion of deaths in the week before the holiday to the total deaths in the week before and after the holiday, we can use the formula:
p ± z √(p(1- p/ n)
where p is the sample proportion, z is the z-score, and n is the sample size.
In this case, the sample proportion is p = 4968/10000 = 0.4968.
The z-score corresponding to a 90% confidence interval is approximately 1.645. The sample size is n = 10000.
Substituting these values into the formula, we get:
0.4968 ± 1.645 √((0.4968 * 0.5032) / 10000)
Calculating this expression gives us the confidence interval estimate.
Based on the result, we can assess whether there is an indication that people can temporarily postpone their death to survive the holiday. If the lower limit of the confidence interval is significantly lower than the proportion of deaths in the week after the holiday, it suggests that there is a decrease in deaths in the week before the holiday. However, if the lower limit is close to or higher than the proportion of deaths in the week after the holiday, it indicates that there is no evidence of a significant decrease in deaths before the holiday.

Find tan θ if sec θ = square root of thirty seven divided by six and sin θ < 0.
tan(θ) = -1/6.
Given that sec(θ) = √37/6 and sin(θ) < 0, we can find tan(θ) using the trigonometric identity:
sec²(θ) - tan²(θ) = 1
First, we need to find the value of tan(θ) using the given information:
Since sec(θ) = √37/6, we know that sec(θ) = 1/cos(θ), so cos(θ) = 6/√37.
Since sin²(θ) + cos²(θ) = 1, we can find sin(θ):
sin²(θ) + (6/√37)² = 1
sin²(θ) + 36/37 = 1
sin²(θ) = 1 - 36/37
sin²(θ) = (37-36)/37
sin²(θ) = 1/37
Given that sin(θ) < 0, sin(θ) is negative. Therefore, sin(θ) = -1/√37.
Now that we have sin(θ) and cos(θ), we can find tan(θ):
tan(θ) = sin(θ)/cos(θ)
tan(θ) = (-1/√37) / (6/√37)
tan(θ) = -1/6
Therefore, tan(θ) = -1/6.

four years after a hedge maple tree was planted, its height was 9 feet. eight years after it was planted, the hedge maple tree's height was 12 feet. what is the growth rate of the hedge maple? what was its height when it was planted?? ...?
The growth rate of the hedge maple tree is 0.75 feet per year, and the tree's original height when it was planted was 6 feet.
Explanation:We are tasked with finding the growth rate of a hedge maple tree and its original height when it was planted based on the given data. The tree's height was recorded at two different times: Four years after it was planted, its height was 9 feet, and eight years after planting, its height reached 12 feet.
To calculate the growth rate per year, we take the difference in height over the difference in time:
Growth rate = (Height at 8 years - Height at 4 years) / (Time at 8 years - Time at 4 years)
Thus, Growth rate = (12 feet - 9 feet) / (8 years - 4 years) = 3 feet / 4 years = 0.75 feet per year.
To determine the original height when the tree was planted, we can subtract the total growth over the four years from the height at four years after planting:
Original height = Height at 4 years - (Growth rate * 4 years)
Original height = 9 feet - (0.75 feet/year * 4 years) = 6 feet.

What is the Perimeter of a Rectangle?The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.
Perimeter P of rectangle = 2 ( Length + Width )
Given data ,
Let the perimeter of the rectangle be P = 48 feet
We can use the equation given to solve for the width w of the garden:
2l + 2w = 48
Substituting l = 15, we get:
2(15) + 2w = 48
30 + 2w = 48
Subtracting 30 from both sides, we get:
2w = 18
Dividing both sides by 2, we get:
w = 9 feet

Step-by-step explanation:
Given : sin θ = 3/5
To Find : value of cos θ and tan θ
Solution :
use the identity:
[tex]sin^{2}\Theta +cos^{2}\Theta =1[/tex]
putting value of sin θ
⇒ [tex](\frac{3}{5})^{2} + cos^{2}\Theta =1[/tex]
⇒[tex]\frac{9}{25} +cos^{2}\Theta =1[/tex]
⇒[tex]cos^{2}\Theta = 1-\frac{9}{25}[/tex]

Thus , [tex]cos\Theta =\frac{4}{5}[/tex]
Now to find value of tan θ
Since we know that

⇒[tex]tan\Theta =\frac{\frac{3}{5} }{\frac{4}{5} }[/tex]
⇒[tex]tan\Theta =\frac{3}{5}\div \frac{4}{5}[/tex]
⇒[tex]tan\Theta =\frac{3}{5}\times \frac{5}{4}[/tex]
⇒[tex]tan\Theta =\frac{3}{4}[/tex]
Thus , the value of
[tex]tan\Theta =\frac{3}{4}[/tex]
[tex]cos\Theta =\frac{4}{5}[/tex]
Final answer:
This detailed answer provides the values of cos θ and tan θ for an angle θ in the second quadrant given sin θ = 3/5. It explains the process using the Pythagorean identity and the characteristics of the second quadrant.
Explanation:
cos θ = -4/5
tan θ = -3/4
Given sin θ = 3/5 and the angle θ lies in the second quadrant, we can determine cos θ using the Pythagorean identity. Since sin θ = 3/5 is positive in the second quadrant, the x-coordinate in the triangle would be negative. Therefore, cos θ = -4/5. Similarly, tan θ can be calculated as tan θ = sin θ / cos θ = (3/5) / (-4/5) = -3/4.
