Fractions and ratios can be simplified the same way.
Fractions and ratios are different names for the same thing.
Some fractions and ratios can be written as mixed numbers.
Answer:
b and c
Step-by-step explanation:
The statements that are true are:
Fractions and ratios cannot have zero in the denominator.
Fractions and ratios can be simplified in the same way.
Fractions and ratios are different names for the same thing.
Options A, B, and C are correct.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Fraction is written as:
1/2, 3/4, 5/6
Where 1, 3, and 5 are numerators and 2, 4, and 6 are denominators.
The ratio is written in the form a:b.
1:2 = 1/2
4:8 = 4/8 = 1/2
Fractions and ratios cannot have zero in the denominator.
This is true because if we have zero in the denominator the fraction becomes undefined.
Example:
1/0 = ∞
The ratio can not have zero in the denominator because we are comparing two units where neither one unit can be zero.
Fractions and ratios can be simplified in the same way.
This is true.
Example:
Fraction = 2/4 = 1/2
Ratio = 2:4 = 2/4 = 1/2
Fractions and ratios are different names for the same thing.
This is true.
Because ratio can be written as a fraction.
Example: 2:3 = 2/3
Some fractions and ratios can be written as mixed numbers.
This is not true
Fractions can be written as a mixed numbers.
Example:
5/2 = [tex]2\frac{1}{2}[/tex]
Ratios can never be written as a mixed number.
Thus,
The statements that are true are:
Fractions and ratios cannot have zero in the denominator.

Suppose that at Northside High, the number of hours per week that seniors spend on homework is approximately Normally distributed with a mean of 18.6 and a standard deviation of 6. We take a random sample of 36 seniors. What is the mean and standard deviation of the sampling distribution for the 36 students?
Answer:
The mean and standard deviation of the sampling distribution for the 36 students will be:
Mean = 18.6
Standard deviation = 6
Step-by-step explanation:
The mean and standard deviation of the sampling distribution is equal to the population mean and standard deviation respectively. The only difference is that the population mean and standard deviation are parameters or fixed values calculated from every individual in the population, while the sample mean and standard deviation are statistics. Statistics are calculated from only some of the individuals in a population. They are meant to represent or approximate the population parameters.

Given that f (x) = x help me plz
Answer:
Step-by-step explanation:
f(x) + g(x) = x^2 - 2x + x + 12
f(x) + g(x) = x^2 - x + 12
(f + g)( -1) = 1 + 1 + 12 = 14
f(x) - g(x) = x^2 - 2x - x - 12
f(x) - g(x) = x^2 - 3x - 12
(f + g)(-1) = (-1)^2 -(3)(-1) -12
(f + g)(-1) = 1 + 3 - 12
(f + g)(-1) = - 8

The price of an item yesterday was $120. Today, the price rose to $294. Find the percentage increase.
Answer:
145%.
Step-by-step explanation:
Given that the price of an item yesterday was $120, and today, the price rose to $294, in order to find the percentage increase, the following calculation has to be made:
120 = 100
294 = X
((294 x 100) / 120) = X
29,400 / 120 = X
245 = X
245 - 100 = 145
Therefore, the percentage increase of the product was of 145%.
can be used to compare changes from one period to another.
a) Decimals
b) Fractions
c) Percentages
d) Digits
Answer:
c) Percentages
Step-by-step explanation:
Percentages can be used to compare changes from one period to another.
In calculating a percentage change, either a percentage increase or percentage decrease, we must have both the new and old measurement of the specific quantity.
For example, let's find percentage increase of the number of students that joined a book club using the parameters below;
Original number of students = 32
New number of students = 36
We will calculate the increase using;
[tex] Increase = original \; number - new \; number [/tex]
Substituting the values, we have;
Increase = 36 - 32 = 4
[tex] Percentage \; increase = \frac{increase}{original \; number} * 100[/tex]
[tex] Percentage \; increase = \frac{4}{32} * 100[/tex]
[tex] Percentage \; increase = 0.125 * 100[/tex]
Percentage increase = 12.5%
Therefore, the number of students in the school club increased by 12.5%.

Answer:
f(x) = -0.5x - 2;
At x = 0, f(x) = -2
At x = 1, f(x) = -2.5
At x = 2, f(x) = -3
At x = 3, f(x) = -3.5
At x = 4, f(x) = -4
g(x) = (2^(x - 1)) - 5;
At x = 0, g(x) = -4.5
At x = 1, g(x) = -4
At x = 2, g(x) = -3
At x = 3, g(x) = -1
At x = 4, g(x) = 3
Step-by-step explanation:
First equation;
f(x) = -0.5x - 2
f(0) = -0.5(0) - 2 = -2
f(1) = -0.5(1) - 2 = -2.5
f(2) = -0.5(2) - 2 = -3
f(3) = -0.5(3) - 2 = -3.5
f(4) = -0.5(4) - 2 = -4
For the second equation;
g(x) = (2^(x - 1)) - 5
g(0) = (2^(0 - 1)) - 5 = 2^(-1) - 5 = -4.5
g(1) = (2^(1 - 1)) - 5 = 2^(0) - 5 = -4
g(2) = (2^(2 - 1)) - 5 = 2 - 5 = -3
g(3) = (2^(3 - 1)) - 5 = 4 - 5 = -1
g(4) = (2^(4 - 1)) - 5 = 3
A truck is carrying passion fruit juice, cherry juice, and mango juice bottles in a ratio 1:2:7. If there are 34 cherry juice bottles, then how many nango juuce bottles are there?
Answer:
Step-by-step explanation:
We can solve this using a ratio. If there a 2 bottles of cherry in the ratio and there are 34 actual bottles of cherry, then the ratio is
[tex]\frac{ratio}{actual}:\frac{2}{34}[/tex]
In the ratio, we are told that the mix of bottles is 7 parts mango and we want to know how many actual bottles there are of mango. So filling in:
[tex]\frac{ratio}{actual} =\frac{2}{34} =\frac{7}{m}[/tex] and cross multiply to get
2m = 238 and
m = 119. There are 119 bottles of mango juice. And just for the record, there are 17 bottles of fruit juice.
Answer:
m = 119. There are 119 bottles of mango juice. there are 17 bottles of fruit juice.

C.) Domain: 0
The domain represents the set of all possible outputs - the various depths of the pool.
D.) Domain: 0≤x≤16
The domain represents the set of all possible inputs - the times when depth was measured.
Answer:
D.) Domain: 0≤x≤16
The domain represents the set of all possible inputs - the times when depth was measured
Step-by-step explanation:
Domain of a function is the possible set of inputs which are usually plotted on the x-axis, while range are corresponding outputs plotted on the y-axis.
In this case, the domain is the set of all possible inputs (x-values), which represents the times the depth was measured.
Domain ranges from 0 to 16. Thus:
Domain: 0 ≤ x ≤ 16

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 10 more than the second.
Answer:
first angle be 30°
second angle be 70°
third angle be 80°
Step-by-step explanation:
first angle be x
second angle be y
third angle be z
x+y+z=180
given, y+z = 5x; z=5x-y
also, z=y+10
5x-y = y+10
5x= 10+y+y = 10+2y
x= (10+2y)/5
x+y+z=180
(10+2y)/5 + y + y+10 = 180
(10+2y)/5 = 180 -2y -10
(10+2y)/5 = 170-2y
multiply both sides by 5
10+2y = 5(170-2y)
10+2y= 850-10y
2y+10y = 850-10
12y= 840
y= 840/12 = 70°
z=y+10 =70+10= 80°
5x= (10+2y) = 10+2(70) = 10+140= 150
x = 150/5 = 30°

Segment AB is dilated from the origin to create segment A prime B prime at A' (0, 4) and B' (4, 6). What scale factor was segment AB dilated by?
Answer choices:
A. 1/2
B. 2
C. 3
D.4
Given:
Endpoint of segment AB are A(0,2), B(2,3).
Segment AB is dilated from the origin to create segment A prime B prime at A' (0, 4) and B' (4, 6).
To find:
The scale factor of dilation.
Solution:
If a figure is dilated about the origin with factor k, then
[tex](x,y)\to (kx,ky)[/tex]
Using this rule, we get
[tex]A(0,2)\to A'(k(0),k(2))[/tex]
[tex]A(0,2)\to A'(0,2k)[/tex]
So, the image of A is A'(0,2k).
It is given that image of A is A'(0,4). So,
[tex]A'(0,2k)=A'(0,4)[/tex]
On comparing the y-coordinates from both sides, we get
[tex]2k=4[/tex]
[tex]k=\dfrac{4}{2}[/tex]
[tex]k=2[/tex]
Therefore, the scale factor is 2 and the correct option is B.
Dilation involves changing the size of a line
The scale factor is 2.
From the graph, the coordinates of AB are:
[tex]\mathbf{A = (0,2)}[/tex]
[tex]\mathbf{B = (2,3)}[/tex]
The coordinates of AB are:
[tex]\mathbf{A' = (0,4)}[/tex]
[tex]\mathbf{B' = (4,6)}[/tex]
Divide A' by A or B' by B to calculate the scale ratio (k)
[tex]\mathbf{k = \frac{A'}{A}}[/tex]
So, we have:
[tex]\mathbf{k = \frac{(0,4)}{(0,2)}}[/tex]
Expand
[tex]\mathbf{k = \frac{2(0,2)}{(0,2)}}\\[/tex]
Divide
[tex]\mathbf{k = 2}\\\\\\\\[/tex]
Hence, the scale factor is 2.

This triangle has one side that lies on an extended line segment.
Based on this triangle, what statement about x is true?
x= 33 because 180 – 147 = 33
x = 62 because 147 – 85 = 62 and 85 + 62 = 147
x = 95 because 180 – 85 = 95 and 85 + 95 = 180
x = 118 because
180 147 + 85
33 + 85
=118
Answer:
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
Step-by-step explanation:
We are given that
[tex]\angle ABC=85^{\circ}[/tex]
Exterior angle=[tex]147^{\circ}[/tex]
We have to find the value of x.
We know that
Exterior angle=Sum of opposite interior angles of triangle
Using the property
[tex]x+85=147[/tex]
Subtract 85 from both sides we get
[tex]x=147-85[/tex]
[tex]x=62[/tex]
Option B is true.
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
