0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part is
\(12 = 0.005 \times w\)
Now to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite
\(w = \frac{12}{0.005} = 2400\)

You find range by subtracting the lowest amount from your data by the highest amount. The highest number in Ms. Gambino's class is 12, and the lowest is 5.
\(12-5=7\) This is the range of Ms. Gambino's class
The highest number in Mr. Joe's class is 10 and the lowest is 5
\(10-5=5\\\) This is the range of Mr. Joe's class.
Therefore, the range in Mr. Joe's class is less than the range of data in Ms. Gambino's class.
The mean annual salary paid to all employees in a company was 1500 Kenya pounds The mean annual salaries paid to male and female employees were 1560 Kenya pounds and 1260 Kenya pounds respectively. Determine the percentages of males and females employed by the company.
Answers
Answer:
\(Male = 80\)%
\(Female = 20%\)%
Step-by-step explanation:
Given
Annual Mean Salary = 1500
Annual Mean Salary (Male) = 1560
Annual Mean Salary (Female) = 1260
Required
Percentage of male and female employed
Represent male by m and female by 4
So, total employees = m + f
The mean of an observation is calculated as thus;
Mean = Summation of observation divided by number of observations
For Male:
Annual Mean = Total Salary/Number of males
Recall that Annual Mean = 1560
Number of males = m;
The formula becomes
\(1560 = \frac{TotalSalary}{m}\)
Multiply both sides by m
\(1560 * m = \frac{TotalSalary}{m} * m\)
\(1560m = TotalSalary\)
For Female:
Annual Mean = Total Salary/Number of females
Recall that Annual Mean = 1260
Number of females = f;
The formula becomes
\(1260 = \frac{TotalSalary}{f}\)
Multiply both sides by f
\(1260 * f = \frac{TotalSalary}{f} * f\)
\(1260f = TotalSalary\)
Total Annual Salary = Annual Salary of Male + Annual Salary of Female
Total Annual Salary = 1560m + 1260f
The mean annual salary is calculated as thus;
Mean Annual Salary = Total Annual Salary/Total Employees
Recall that Total Employees = m + f and Mean Annual Salary = 1500
So, the formula becomes
\(1500 = \frac{1560m + 1260f}{m+f}\)
Multiply both sides by m + f
\(1500(m+f) = \frac{1560m + 1260f}{m+f} * (m+f)\)
\(1500(m+f) = 1560m + 1260f\)
Open brackets
\(1500m+1500f- = 1560m + 1260f\)
Collect like terms
\(1500f -1260f = 1560m - 1500m\)
\(240f = 60m\)
Divide through by 60
\(\frac{240f}{60} = \frac{60m}{60}\)
\(4f = m\)
Reorder
\(m = 4f\)
At this point, the percentage male and female can be calculated;
Male = (Number of male/Total Employees) * 100%
\(Male = \frac{m}{m+f} * 100\)%
Substitute 4f for m
\(Male = \frac{4f}{4f+f} * 100\)%
\(Male = \frac{4f}{5f} * 100\)%
\(Male = \frac{4}{5} * 100\)%
\(Male = 0.8 * 100\)%
\(Male = 80\)%
If percentage of male = 80%
Percentage of Female = 100% - 80%
\(Female = 20%\)%

10.a jar of 70 candies has the following colors: 28 orange, 7 white, 14 brown, and 21 yellow.what is the probability of randomly drawing a candy that is not brown, replacing it, and then drawing a orange candy?
Answers
The total number of candies in the jar is 70, out of which 14 are brown. Therefore, the number of candies that are not brown is 70 - 14 = 56.
To find the probability of drawing a candy that is not brown, replacing it, and then drawing an orange candy, we can use the multiplication rule of probability. According to this rule, the probability of two independent events occurring together is the product of their individual probabilities.
So, the probability of drawing a candy that is not brown on the first draw is 56/70. After replacing the candy, there are still 70 candies in the jar, so the probability of drawing an orange candy on the second draw is 28/70.
Multiplying these probabilities, we get:
(56/70) x (28/70) = 0.16
Therefore, the probability of randomly drawing a candy that is not brown, replacing it, and then drawing an orange candy is 0.16 or 16%.

Answer:
D.) 37.65

I know that 8 is an input based on this word problem. So, then I plug in the 8 for z and solve to find the expected height of the tree in 8 years.
y=4.3z+3.25
y=4.3(8)+3.25
y=34.4+3.25
y=37.65
In 8 years the expected height of the tree is 37.65

A set of numbers represents the range of this function as whole numbers greater than 0.
What is the range or domain of a function?The domain of a function is the set of values that we are allowed to enter into our function. This set consists of the x values for a function like f. (x). The set of values that a function may accept as input is known as its range. The function outputs this list of values once we enter an x value.
The collection of all potential output values that a function might produce is known as its range.
In this instance, the function displays the positive whole integer representing the number of persons entering the performance hall each minute.
The set of whole integers bigger than 0 is hence the range of the function.
The appropriate response is thus A. Whole numbers larger than 0.

-8x - 8 is the only expression equivalent to 16x - 12 - 24x + 4
Step-by-step explanation:
The easiest way you can do this problem is by substituting any number for x, for all of the expressions. That way you can compare the expressions. Let's choose to use 1 for example. So, x = 1.
If x = 1, you plug 1 in for all the x's. So, 16x - 12 - 24x + 4 would look like
16(1) - 12 - 24(1) + 4 = -16. Now let's see if any of the other expressions would ALSO equal -16 if x = 1.
4 + 16(1) - 12(1 + 2(1)) = 6
40(1) - 16 = 24
16(1) - 24(1) - 4 + 12 = 0
-8(1) - 8 = -16
Therefore, -8x - 8 is the only equivalent expression :)
Beth's class took a field trip to the art museum. It took them 55 minutes to drive to the museum. They stayed at the museum for 1 hour and 33 minutes. When the class left the museum, it was 9:41 A.M. What time did Beth's class leave for the field trip?
PLS HELPPPP I give 50.
Answers
Answer:
Beth's class left for the field trip at 7:13 A.M..
Step-by-step explanation:
To find out what time Beth's class left for the field trip, we need to subtract the time elapsed at the museum and the time it took them to drive there from 9:41 A.M.
The time elapsed at the museum was 1 hour and 33 minutes which is equivalent to 93 minutes.
To find out what time they left for the field trip, we need to subtract 55 minutes (the time it took them to drive there) and 93 minutes (the time they spent at the museum) from 9:41 A.M.
9:41 A.M. minus 55 minutes is 8:46 A.M..
8:46 A.M. minus 93 minutes is 7:13 A.M..
Therefore, Beth's class left for the field trip at 7:13 A.M..
