Answer:
7.6 inches
Step-by-step explanation:
The ratio of the height to the width of a packaging label is 5 to 19, that is,
h/w = 5/19 [1]
If the height of the label is 2 inches, and its width is unknown (x), that is,
h/w = 2 in/x [2]
We can set up a proportion with [1] and [2],
5/19 = 2 in/x
We use the cross product property of proportions.
5 × x = 19 × 2 in
x = 19 × 2 in/ 5 = 7.6 in
The width is 7.6 inches.

Final answer:
The probability that a randomly selected worker has one month's income or more set aside for emergencies is approximately 0.479. Given that a randomly selected worker is a male, the probability that the worker has less than one month's income is approximately 0.460. Given that a randomly selected worker has one month's income or more set aside for emergencies, the probability that the worker is a female is approximately 0.446. The events 'having less than one month's income saved' and 'being male' are independent.
Explanation:
To find the probability that a randomly selected worker has one month's income or more set aside for emergencies, we need to divide the number of workers with one month's income or more by the total number of workers. According to the table, there are 76 men and 61 women with one month's income or more, for a total of 137 workers. The total number of workers is 286. So the probability is 137/286, which is approximately 0.479.
Given that a randomly selected worker is a male, we need to find the probability that the worker has less than one month's income set aside for emergencies. According to the table, there are 65 men with less than one month's income. The total number of men is 141. So the probability is 65/141, which is approximately 0.460.
Given that a randomly selected worker has one month's income or more set aside for emergencies, we need to find the probability that the worker is a female. According to the table, there are 61 women with one month's income or more. The total number of workers with one month's income or more is 137. So the probability is 61/137, which is approximately 0.446.
The events 'having less than one month's income saved' and 'being male' are independent. To confirm independence, we need to check if the probability of both events occurring is equal to the product of their individual probabilities. In this case, the probability of having less than one month's income saved is 65/286 and the probability of being male is 141/286. The probability of both events occurring is (65/286) * (141/286), which is approximately 0.126. This is equal to the product of their individual probabilities, confirming that the events are independent.

Write the expression as the sine, cosine, or tangent of an angle. cos 8x cos 2x - sin 8x sin 2x
Answer:
cos (A - B) = cos 6 x
Step-by-step explanation:
given equation,
= cos 8 x . cos 2 x - sin 8 x . sin 2 x
using identity
cos (A - B) = cos (A) . cos(B) - sin (A) . sin(B)...................(1)
cos 8 x . cos 2 x - sin 8 x . sin 2 x......................................(2)
comparing both the equation (1) and (2)
we get ,
A = 8 x B = 2 x
hence, from the above identity we can see that
cos (A - B) = cos (8 x - 2 x)
cos (A - B) = cos 6 x

which of these is the absolute value parent function?
A. f(x) = |x| – 2
B. f(x) = |x|
C. f(x) = |2x|
D. f(x) = |x| + 1
Answer:
The correct option is B. The absolute value parent function is f(x) = |x|.
Step-by-step explanation:
The absolute parent function is a function where
[tex]f(x)=x[/tex] and [tex]f(-x)=x[/tex]
The graph of absolute function is v-shaped and vertex of the function is (0,0).
According to these conditions the absolute value parent function is
f(x) = |x|
The function f(x) = |x| – 2 shifts 2 units down.
The function f(x) = |2x| stretch by factor 2.
The function f(x) = |x| + 1 shifts 1 units up.
Therefore the correct option is B.

a plumber charges a base fee of $55 for a service call plus $35 per hour for each hour worked during the service call the relationship between the total price of the service called and the number of hours worked
The relationship between the total price and the number of hours worked can be represented by a linear equation. The equation is y = 35x + 55, where y represents the total price and x represents the number of hours worked.
Explanation:The relationship between the total price of the service call and the number of hours worked can be represented by a linear equation. We can use the formula y = mx + b, where y represents the total price, x represents the number of hours worked, m represents the hourly fee, and b represents the base fee.
In this case, the plumber charges a base fee of $55 and $35 per hour. So the equation that expresses the total price is y = 35x + 55.
The independent variable in this situation is the number of hours worked, which is x. The dependent variable is the total price, which is y. The y-intercept of the equation is 55, which represents the base fee. The slope of the equation is 35, which represents the hourly fee. The y-intercept (b) is the point where the line intersects the y-axis, and the slope (m) determines how steep the line is.

c. 1/2, 11/20, 0.51
d. 0.51, 1/2, 11/20
Answer: Option 'b' is correct.
Step-by-step explanation:
Since we have given that
[tex]\frac{11}{20},\frac{1}{2},0.51[/tex]
Now, we have to arrange the set of numbers from least to greatest.
So, for this we have to make the denominator same ,
[tex]\frac{11\times 5}{20\times 5}=\frac{55}{100}[/tex]
Similarly,
[tex]\frac{1\times 50}{2\times 50}=\frac{50}{100}[/tex]
Similarly,
[tex]\frac{51}{100}[/tex]
Numbers In increasing order :
[tex]\frac{50}{100},\frac{51}{100},\frac{55}{100}\\\\\frac{1}{2},0.51,\frac{11}{20}[/tex]
Hence, Option 'b' is correct.
