Answer: Answer below
Step-by-step explanation:
We start off by subtracting 120 from 150, since we want to find the amount it decreased and not what percentage is left.
150 - 120 = 30
We now divide it by 150 to get our percentage.
30/150 = 1/5
1/5 = 0.2 or 20%
Our answer is 20%.

2. Based on the information in the two-way table, what is the probability that a person selected at random is a right-handed?
A.) 56%
B.) 44%
C.) 10%
D.) 90%
Probabilities are used to determine the chances of events
The probability that a person selected at random is a left-handed male is 5/121The probability that a person selected at random is a right-handed is 109/121How to determine the probabilities?Probability that a person selected at random is a left-handed male
From the table, the number of left-handed male is 5, and a total of 121 people were surveyed.
The probability is then calculated as:
[tex]p = \frac{5}{121}[/tex]
Hence, the probability that a person selected at random is a left-handed male is 5/121
Probability that a person selected at random is a right-handed
From the table, the number of right-handed people is 109
The probability is then calculated as:
[tex]p = \frac{109}{121}[/tex]
Hence, the probability that a person selected at random is a right-handed is 109/121

Using it's concept, it is found that the probabilities are as follows:
1. A.) 4%
2. D.) 90%
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Item 1:
Total of 121 people, 5 are left handed males, hence:
p = 5/121 = 0.0413 = 4%.
Item 2:
109 out of 121 people are right-handed, hence:
p = 109/121 = 0.9 = 90%.

A pizza is cut into pieces. Kevin takes 1/4 of the total pieces. Keith takes one piece less than twice the number of pieces Kevin took. How many of pizza are left ?
a. 1/4x
b. 1/4x+1
c. 1/2x+1
d. 3/4x-1
Answer: I believe the answer is d or b
Step-by-step explanation:
The number of pizza pieces left is (x + 4) / 4. Option c
How to determine the number of pizza pieces leftLet's assume the total number of pizza pieces is represented by 'x'.
Kevin takes 1/4 of the total pieces, which is (1/4) * x = x/4.
Keith takes one piece less than twice the number of pieces Kevin took, which is 2 * (x/4) - 1 = (2x/4) - 1 = x/2 - 1.
To calculate the number of pizza pieces left, we need to subtract the sum of Kevin's and Keith's pieces from the total number of pieces (x):
Leftover pieces = Total pieces - (Kevin's pieces + Keith's pieces)
= x - (x/4 + x/2 - 1)
= x - (3x/4 - 1)
= x - 3x/4 + 1
= (4x - 3x + 4) / 4
= (x + 4) / 4
Therefore, the number of pizza pieces left is (x + 4) / 4.
The correct option among the given choices would be (c) 1/2x + 1.

The diagonal of a quadrilateral shaped field is 24 m and the perpendiculars dropped on it from the remaining opposite vertices are 8 m and 13 m. Find the area of the field.
Put the values
Area:-
[tex]\\ \rm\Rrightarrow \dfrac{1}{2}(24)(8+13)[/tex]
[tex]\\ \rm\Rrightarrow 12(21)[/tex]
[tex]\\ \rm\Rrightarrow 252m^2[/tex]
Answer:
Step-by-step explanation:
Divide the quadrilateral field into two triangles by its diagonal.
Area of a triangle is given by the equation 1/2*base*height.
The top triangle's area = 1/2*24*13 = 156 m^2
The bottom triangle's area = 1/2*24*8 = 96 m^2
Combining, the area of the field = 156 + 96 = 252 m^2

Hello!
This is a trapezoid. It is a quadrilateral with one pair of parallel sides while other sides are non-parallel. Here, the opposite angles are alternate, that is, they have together 180°.
Isosceles trapezoid
An isosceles trapezoid is a trapezoid with congruent base angles and congruent non-parallel sides. Here, the base angles are the same.
The line segment joining the midpoints of the parallel sides is perpendicular to the bases and the diagonals are the same in length.

rosa has a goal of running a total of 150 miles this month each day she ran for 6 miles . what expression could rosa use to determine how many miles she has left to run after running for d days
Answer:
miles left = 150 - 6d
Step-by-step explanation:
To create this expression, let 150 be the total number of miles she needs to run. If she runs 6 miles every day, the expression for miles she has left is the total miles - 6* how many days she has been running. Your final expression for miles she has left should be 150 - 6d.

* 4. A circle is divided into ten equal sectors.
a. Find the measure of each central angle.
b. If the diameter is 50 in., find the length of an arc of one of the
sectors.
HELP PLEASE
Answer:
a. Find the measure of each central angle.
The central angle of a circle = 360 °
Now Pie is cut into 10 equal sectors
Angle of each sector is given by
Angle of sector = Total central angle/number of sectors
[tex] = {360}^{0} \div 10[/tex]
[tex] = {36}^{0} [/tex]
Hence , the central angle of one slice of pie is 36°
b. If the diameter is 50 in., find the length of an arc of one of the sectors.
length of an arc of one of the sectors =
[tex] = \frac{1}{n} \times 2\pi \times r[/tex]
[tex]= \frac{1}{10} \times 2\ \frac{22}{7} \times 50[/tex]
[tex] = 31.42 \: in[/tex]
Answer: 36 degrees
Step-by-step explanation:
A circle is 360 degrees.
If you divide 360 degrees by 10, (10 sectors) you get 36.
The answer is therefore 36 degrees. (don't forget your labels!!!)

Find the value of k if the remainder is 13 when
25 + 4x4 + kx3 + x – 11 is divided by x + 3
Answer:
[tex]k = \frac{322}{27} [/tex]
Step-by-step explanation:
x + 3 = 0 → x = - 3
25 + 4(-3)⁴ + k(-3)³ + (-3) - 11 = 13
25 + 324 - 27k - 3 - 11 = 13
349 - 27k - 14 = 13
349 - 14 - 13 = 27k
349 - 27 = 27k
322 = 27k
k = 322/27
