Answer:
To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction.
So, 7/10 divided by 1/3 can be written as:
(7/10) ÷ (1/3) = (7/10) x (3/1)
Multiplying the numerators and denominators, we get:
(7 x 3) / (10 x 1) = 21/10
Therefore, the answer is 21/10, which is an improper fraction. We can simplify it to a mixed number by dividing the denominator into the numerator.
21 ÷ 10 = 2 with a remainder of 1, so the mixed number is:
= 1 1/10
Hence, the answer is 1 1/10 or 11/10.
Step-by-step explanation:
7/10 / (1/3) is equal to 7/10 * 3/1 = (7*3) / (10*1) = 21/10 = 2 1/10
A company is criticized because only 13 of 43 people in executive-level positions are women. The company explains that although this proportion is lower than it might wish, it’s not surprising given that only 40% of all their employees are women. What do you think? Test an appropriate hypothesis and state your conclusion.
To test whether the proportion of women in executive-level positions is significantly lower than the proportion of women in the company as a whole, we can perform a hypothesis test.
Null Hypothesis: The proportion of women in executive-level positions is equal to or greater than the proportion of women in the company as a whole.
Alternative Hypothesis: The proportion of women in executive-level positions is significantly lower than the proportion of women in the company as a whole.
Using a significance level of 0.05, we can perform a one-tailed z-test for the difference in proportions.
Assuming a total sample size of 43 executives and a proportion of women in the company as a whole of 0.4, we find that the expected number of women in executive-level positions would be 43*0.4 = 17.2.
Using a z-test, we find that the test statistic is z = (13-17.2)/sqrt(0.4*0.6/43) = -1.89.
Using a z-table, we find that the p-value for z = -1.89 is approximately 0.029.
Since the p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that the proportion of women in executive-level positions is significantly lower than the proportion of women in the company as a whole. The company's explanation is not sufficient to account for the observed discrepancy.

Marcus buys a car for $45,000. If he finances it for 5
years at an annual interest rate of 8.5%, what will his
monthly payment be?
Answer:
M ≈ $933.24
Step-by-step explanation:
To calculate Marcus's monthly payment for financing his car for 5 years at an annual interest rate of 8.5%, we can use the formula for the monthly payment on a loan:
M = P * (r/12) * (1 + r/12)^n / ((1 + r/12)^n - 1)
where:
M is the monthly payment
P is the principal (in this case, $45,000)
r is the annual interest rate (in this case, 8.5%)
n is the number of monthly payments (in this case, 5 years * 12 months/year = 60 monthly payments)
Substituting the given values, we get:
M = $45,000 * (0.085/12) * (1 + 0.085/12)^60 / ((1 + 0.085/12)^60 - 1)
Using a calculator, we get:
M ≈ $933.24
Therefore, Marcus's monthly payment for financing his car for 5 years at an annual interest rate of 8.5% is approximately $933.24.

What is square?
Square, in geometry, a plane figure with four equal sides and four right (90°) angles. A square is a special kind of rectangle (an equilateral one) and a special kind of parallelogram (an equilateral and equiangular one).
the area of a parallelogram, we can split this shape up into a rectangle and two right triangles.
The rectangle:
The rectangle has dimensions of 4 by 3 centimeters therefore the area would be 4*3=12 cm squared
two right triangles:
The area of a triangle is 1/2 base * height, but since there are two triangles it would just be the base times the height. The base is 3 cm and the height is 3 so 3*3=9
Next, we add the two areas together: 12+9 = 21

The area of the path is 80 square meters.
Given: A rectangular flower bed measures 10m by 6m. It has a path 2m wide around it.
To Find: The area of the path.
Solution: We need to subtract the area of the inner rectangle from the area of the outer rectangle.

For the given frequency table, (a) 5 (b) 137 (c) lower class boundary is 132.5, and the upper class boundary is 141.5.
What is a frequency table ?
A frequency table is a tabular summary of data showing the frequency (i.e., the number of occurrences) of each category or value in a data set. It usually consists of two columns: one listing the categories or values and the other listing the corresponding frequencies. Frequency tables are commonly used to summarize categorical data, but they can also be used to summarize numerical data by grouping it into intervals or classes.
Now,
(a) The class width is the difference between the upper class limit and the lower class limit. For this frequency distribution, we can see that the class width is the same for each class and is equal to 5.
(b) The class midpoints are found by taking the average of the lower and upper class limits. For the first class, the lower class limit is 135 and the upper class limit is 139. So, the class midpoint is (135 + 139) / 2 = 137.
(c) The class boundaries are found by adding and subtracting half of the class width to the lower and upper class limits. For the first class, the lower class limit is 135 and the upper class limit is 139. The class width is 5, so half of the class width is 2.5. The lower class boundary is 135 - 2.5 = 132.5, and the upper class boundary is 139 + 2.5 = 141.5.

We have to calculate the surface area of the cylinder.
It has a base diameter of 16 inches and a height of 15 inches.
The surface area will be equal to the sum of the area of the base, the area of the top (that is equal to the area of the base) and the lateral surface.
The area of the base can be calculated as:
[tex]\text{A}_{\text{b}}=\dfrac{\pi \text{D}^2}{4}[/tex]
[tex]\text{A}_{\text{b}}=\dfrac{3.14\times16^2}{4}[/tex]
[tex]\text{A}_{\text{b}}=\dfrac{3.14\times256}{4}[/tex]

Tina pet sits to earn extra money. She charges a flat service fee of $20, plus $15 per day. If one of her customers spent less than $125, which of the following inequalities could be used to solve for x, the number of days the customer paid for pet sitting?
Therefore, **x < 7** is the inequality that may be utilized to find x
What is inequality?A mathematical statement known as an inequality compares two expressions using an inequality sign, such as (less than), > (greater than), or (less than or equal to).
For instance, the inequality x + 2 5 signifies that "x + 2 is less than 5".
Let x represent how many days the client paid for pet sitting.
$15 per day plus a $20 fixed service fee equals the total cost of pet sitting.
We are aware that the customer's purchase was under $125. Consequently, we can write:
20 + 15x < 125
Putting this disparity simply:

4) Dane read an average of 400 minutes per week. 5) Diane will have read 2000 minutes after 5 weeks.
How to determine how many minutes did she read each week4) The number "0200100300" represents the number of minutes Diane read each week for 3 weeks. To find out how many minutes she read after the first week, we simply look at the first digit, which is "0." This means that Diane did not read any minutes during the first week.
To find out how many minutes she read after the second week, we add the digits in the first two positions, which are "02." This gives us a total of 2 x 60 = 120 minutes.
To find out how many minutes she read after the third week, we add the digits in the first three positions, which are "020." This gives us a total of 20 x 60 = 1200 minutes.
To find out how many minutes she read each week, we simply divide the total number of minutes by the number of weeks, which is 3. So Diane read a total of 1200 minutes in 3 weeks, which means she read an average of 400 minutes per week.
5) If Diane reads the same number of minutes each week, then she will read that same number of minutes after 4 weeks and after 5 weeks. To find out how many minutes she reads after 4 weeks, we can skip count by the same number repeatedly: 400, 800, 1200, 1600. So Diane will have read 1600 minutes after 4 weeks.
Similarly, to find out how many minutes she reads after 5 weeks, we can skip count again by the same number repeatedly: 400, 800, 1200, 1600, 2000. So Diane will have read 2000 minutes after 5 weeks.

What are fractions?
A fraction represents a portion of a total. This entire may refer to a place or a group of places. The Latin word "fractio," which meaning "to break," is the source of the English term "fraction." It is simpler to identify the greater or smaller fraction when comparing fractions with the same or similar denominators. We must change fractions with dislike or different denominators to fractions with like or the same denominators in order to compare them. To do this, we must determine the denominators' Least Common Multiple (LCM). We can compare fractions simply when the denominators are made the same or similar.

O The solution is incorrect because the student did not correctly identify the intersection.
O The solution is correct and the lines are graphed correctly.
O The solution is correct, but the lines were graphed incorrectly.
O The solution is incorrect because the lines are not graphed correctly.
Answer:
Option A: The solution is incorrect because the student did not correctly identify the intersection.
Step-by-step explanation:
Solve by elimination method.
5x + 2y = 10; -10x + 2y = 1
Multiply the second equation by -1, then add the equations together.
(5x + 2y = 10)
-1 (-10x + 2y = 1)
Forms:
5x + 2y = 10
10x - 2y = -1
Add these equations to eliminate y.
15x = 9
Then solve 15x = 9 for x:
15x = 9
15/15 = 9/15 (Divide both sides by 15)
x = 3/5
Now that we've found x let's plug it back in to solve for y.
Write down the original equation:
5x + 2y = 10
Substitute 3/5 for x in:
5x + 2y = 10:
5(3/4)+2y=10
2y+3=10
2y+3-3=10+-3
2y=7
2y/2 = 7/2
y = 7/2
x = 3/5 and y = 7/2.
Comparing the identified answers to the one found by the students, it can be concluded that Option A: The solution is incorrect because the student did not correctly identify the intersection.

Thus, the area of ΔHIJ using the Heron's formula is found as 580.47 square centimeter.
Explain about the Heron's formula:Heron of Alexandria (c. 62 ce) is credited with developing the Heron's formula, which determines the area of a triangle in regards of the lengths of its sides. If the side lengths are represented by the symbols a, b, and c: √s(s - a)(s - b)(s - c)
where s = half the perimeter,
s = (a + b + c)/2.
given data:
In ΔHIJ,
h = 33 cm, i = 61 cm and j =39 cm.semi -perimeter s = (i + j + h) / 2
s = (33 + 61 + 39) / 2
s = 66.5

s - h = 66.5 - 33 = 33.5
s - i = 66.5 - 61 = 5.5
s - j = 66.5 - 39 = 27.5
area of ΔHIJ = √s(s - h)(s - i)(s - j)
area of ΔHIJ = √66.5*33.5*5.5*27.5

Sample space when two dice are thrown = 36
possible outcome = (2,2),(2,4),(2,6),(4,2),(4,4),(4,6),(6,2),(6,4),(6,6)= 9
Probability = 9/36 = 1/4
For question 2.)
Sample space when two dice are thrown = 36
possible outcome = 18
probability = 18/36 = 1/2
for question 3.)
Sample space when two dice are thrown = 12
possible outcome = 4
probability = 4/12 = 1/3

the temperature at 8 a.m. was -8.7 F. At 1 p.m. it was 9.3 F. What integer represents the change in the temperature from morning to afternoon?
The integer that represents the change in temperature from morning to afternoon is 18.
What is integer?The group of counting numbers that can be written without a fractional component includes zero and both positive and negative integers. An integer can, as was already established, be either positive, negative, or zero.
To find the change in temperature from morning to afternoon, we need to subtract the morning temperature from the afternoon temperature:
9.3 F - (-8.7 F) = 9.3 F + 8.7 F = 18 F
Therefore, the integer that represents the change in temperature from morning to afternoon is 18.
