Answer:
(a)2 1/4
(b)1 1/2
(c)1 1/18
(d)5 7/12
Step-by-step explanation:
(a) 11/3 - 17/12 = 44/12 - 17/12 = 27/12 = 9/4 = 2 1/4
(b) 33/10 - 18/10 = 15/10 = 3/2 = 1 1/2
(c) 41/9 - 7/2 = 82/18 - 63/18 = 19/18 = 1 1/18
(d) 47/6 - 9/4 = 94/12 - 27/12 = 67/12 = 5 7/12
Hope it helped :)
3 8/12 - 1 5/12 = 2 3/12 = 2 1/4
b) 3 3/10 - 1 4/5 we’ll convert to 10ths by multiplying the numerator and denominator of the second mixed number by two.
3 3/10 - 1 8/10
Now we need to borrow from the three wholes to create more tenths
2 13/10 - 1 8/10 = 1 5/10 = 1 1/2
Or you can convert the first one to 33/10, and the second one to 9/5, which becomes 18/10.
33/10 - 18/10 = 15/10 = 1 1/2
Do whichever one makes more sense to your brain.
c) 4 5/9 - 3 1/2 we will convert both to 18ths.
4 10/18 - 3 9/18 = 1 1/18
d) 7 5/6 - 2 1/4 we will convert both to 12ths.
7 10/12 - 2 3/12 = 5 7/12

Answer and Step-by-step explanation:
First step we can do is find the slope of the line.
To find the slope, use the following equation:
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
(2, 0) will be the ([tex]x_{2}, y_{2}[/tex]) set, and (0, 4) will be the ([tex]x_2, x_1[/tex]) set.
[tex]\frac{0 - 4}{2 - 0} = \frac{-4}{2} = -2[/tex]
The slope of the line is -2.
Don't worry about the inequality part yet, make it look like an equation because you'll be more familiar with it.
y = -2x + b (b is the y-intercept)
The y-intercept is the point where the lines intersects with the y-axis. this y-value is 4.
y = -2x + 4 -- That is the equation of the line.
We see that all values make the inequality true is on the left side of this line. This means that the sign to replace the = sign with is >=, in which the values of y are less than what is plugged in and evaluated for x.
y <= -2x + 4
That is the inequality equation.

You have been asked to construct a 95% confidence interval for the population proportion of all young adults in Kentucky who got help from their parents. What is the margin of error for a 95% confidence interval for the population proportion?
a.1.645(0.0040)
b.1.645(0.0632)
c.1.96(0.0040)
d.1.96(0.0632)
Answers
Answer:
d.1.96(0.0632)
Step-by-step explanation:
The margin of error for a 95% confidence interval for the population proportion calculated as below:
Given that x = 8
n = Size of the sample = 40 (Large sample)
Sample population: P=x/n = 8/40 = 0.2; q = 1-p = 0.8
Standard error = [tex]\sqrt{pq/n}[/tex] = [tex]\sqrt{0.2(0.8)}/40[/tex] = 0.0682
95% of confidence Z∝ = 1.96
Margin of Error = Z∝ .[tex]\sqrt{pq/n}[/tex]
Margin of Error = 1.96(0.0682)
So, therefore, option d is correct.
Joe ate twice as many pieces of Halloween candy as Ed. Together they ate 48 pieces.
How many pieces of candy did Ed eat?
A. 12
B. 16
C. 24
D. 32
Answers
Answer: 16
Step-by-step explanation:
Let the number of candy Ed took be denoted as "x"
Since Joe ate twice the amount of candy Ed ate, then the number of candies joe ate will be denoted as "2x"
Since all together they ate a total of 48 candies, then the sum of the candies eaten by Joe and Ed is what gives a total of 48
This means:
2x + x = 48
3x = 48
X = 16.

A. 0.46 B. 0.83 C. 0.41 D. 0.44
Answers
Answer:
probability: 0.44
The probability that a student chosen at random will be 16 or older is 0.44 or 44%.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
The probability that a student chosen at random will be 16 or older is the sum of the probabilities of selecting a 16-year-old or older student.
P(16 or older) = P(16) + P(17) + P(18)
P(16 or older) = 0.28 + 0.15 + 0.01
P(16 or older) = 0.44
Therefore, the probability that a student chosen at random will be 16 or older is 0.44 or 44%.

A helicopter pilot sees an island at a 70° angle of depression from the horizontal. In the
diagram, m<1 =70°. What is m<2? How do you know?
Answers
Answer:
1231 ft
Step-by-step explanation:
Draw a right triangle. Label the height of the triangle. as 800 since the height of the triangle represents the height of the helicopter above the coast of the island. Label the base length of the triangle as d to represent the distance between the coast of the island and the coast of the mainland, P. The angle of depression from the helicopter to point P is 33° so draw a horizontal dotted line at the location of the helicopter and label the angle made by the horizontal line and the hypotenuse of the right triangle as 33°. The angle of elevation from P to the helicopter and the angle of depression from the helicopter to point P are congruent alternate interior angles so label the angle at P as 33°.
The side labeled 800 is opposite of P and the side labeled d is adjacent to P so you can use tangent to write an equation. Solve this equation for d and round to the nearest whole number.

Which linear inequality is represented by the graph?
Oys 2x + 4
Oyszx+ 3
O yz {x + 3
O y 2x + 3
Answers
The linear inequality that represents the graph is: [tex]y \le \frac 23x + \frac 15[/tex]
The line of the inequality passes through the points:
(0,0.2) and (3,2.2)
So, the slope of the line is:
[tex]m = \frac{2.2 - 0.2}{3 - 0}[/tex]
[tex]m = \frac{2}{3 }[/tex]
The equation is then calculated as:
[tex]y =mx + c[/tex]
Where c represents the value of y, when x = 0.
So, we have:
[tex]y =\frac 23x + 0.2[/tex]
Rewrite as:
[tex]y =\frac 23x + \frac 15[/tex]
The down region is shaded, and the line is a closed line.
So, the inequality is:
[tex]y \le \frac 23x + \frac 15[/tex]

Answer:
[tex]\boxed {\boxed {\sf 19.625 \ ft^2}}[/tex]
Step-by-step explanation:
The area of a circle is found using this formula:
[tex]a= \pi r^2[/tex]
We know the circle's diameter is 5 feet, but we don't know the radius. Remember the diameter passes through the center from one side to the other, while the radius connects the center and the side. Therefore, the radius is half the diameter.
r=d/2r= 5 ft/2r= 2.5 ftWe know the radius is 2.5 feet and we are using 3.14 for pi. Substitute the values into the formula.
[tex]a= (3.14)* (2.5 \ ft)^2[/tex]
Solve the exponent.
(2.5 ft)²= 2.5 ft *2.5 ft=6.25 ft²[tex]a= (3.14)*(6.25 \ ft^2)[/tex]
Multiply.
[tex]a=19.625 \ ft^2[/tex]
The area of the circle is 19.625 square feet.

What is the magnitude of -10 + 24i?

Answers
Answer:
The magnitude of the number is of 26.
Step-by-step explanation:
Magnitude of a complex number:
A complex number has the following format: a + bi
In which a is the real coefficient and b is the imaginary coefficient.
The magnitude of the number is:
[tex]\sqrt{a^2+b^2}[/tex]
What is the magnitude of -10 + 24i?
For this number, a = -10, b = 24. So
