Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, select the statement that could be true for g. A. g(-4) = -11 B. g(7) = -1 C. g(-13) = 20 D. g(0) = 2
Answer:
C
Step-by-step explanation:
C can be true, because -13 is inside the defined domain, and 20 is inside the defined range.
A cannot be true, because -11 is outside of the defined range.
B cannot be true, because 7 is outside of the defined domain.
D cannot be true, because g(0) has already a different assigned result value : -2. and in a function no x can have multiple assigned result values.

Answer:
[tex]1\frac{1}{3}[/tex]
Step-by-step explanation:
Given the following question:
[tex]5\frac{1}{3} \div4[/tex]
To find the answer convert the mixed numbers into improper fractions and then divide using KCF. (Keep, Change Flip)
[tex]5\frac{1}{3} \div4[/tex]
[tex]5\frac{1}{3} =3\times5=15+1=16=\frac{16}{3}[/tex]
[tex]\frac{16}{3} \div4[/tex]
[tex]4=\frac{4}{1}[/tex]
[tex]\frac{16}{3} \div\frac{4}{1}[/tex]
Apply KCF:
[tex]\frac{16}{3} \div\frac{4}{1}[/tex]
[tex]\frac{16}{3} \times\frac{1}{4}[/tex]
[tex]16\times1=16[/tex]
[tex]3\times4=12[/tex]
[tex]=\frac{16}{12}[/tex]
Simplify by reducing:
[tex]\frac{16}{12}[/tex]
[tex]16\div4=4[/tex]
[tex]12\div4=3[/tex]
[tex]=\frac{4}{3}[/tex]
Convert into mixed number:
[tex]\frac{4}{3}[/tex]
[tex]\frac{4}{3} =4\div3=1\frac{1}{3}[/tex]
[tex]=1\frac{1}{3}[/tex]
Which means your answer is "4/3 or 1 1/3."

One die shows a 6, and the other is a number less than 4.
Answer:
the probability of rolling a 6 on one die is 1/6 or 16.7 %
the same could be said about rolling a 4 on a similar die.
Help please I’m so confused
Answer:
m<ACD = 124 degrees
Step-by-step explanation:
(2x+8) + (x-2) = 180 degrees
This is because both angles are on the same line (so they are a linear pair) and a straight line is 180 degrees. This means that they are supplementary
So:
(2x+8) + (x-2) = 180
Combine like terms:
2x + x + 8 - 2 = 180
3x + 6 = 180
-6 -6
3x = 174
Divide both sides by 3
x = 58
Now that you know x, you can put it into the equation for m<ACD:
2x+8
(2 multiplied by 58) + 8
(116) + 8
124
m<ACD = 124 degrees

Autosomal dominant disorders are less common than recessive disorders. Why do you think that is?
Reccesive disorders are more common because they are not easily eliminated by natural selection.
What is Autosomal dominant disorders ?The autosomal dominant disorders refers to those disorders that have no gender preference and have possible male to male transmission.
The autosomal dominant disorders are much more rare than the recessive disorders because they do not occur on a s-ex-linked chromosome. Note also that it is more common to have dominant mutations eleiminated by the process of natural selection.

Consider the expression below. 1.3 + 1.25
Sarah thinks that this sum will be an irrational number. Is Sarah's classification correct? Why or why not?
A Sarah is not correct, because 1.3 + 1.25 can be rewritten as + which results in the rational sum of 2
B. Sarah is not correct, because 1.3 + 1.25 results in a decimal number and all decimals are rational.
C. Sarah is correct, because 1.25 cannot be rewritten as a fraction which means the sum is irrational.
D.
Sarah is correct, because 1.3 cannot be rewritten as a fraction or terminating decimal which means the sum is
irrational
Answer:
First, let's find out the sum;
1.30 + 1.25 = 2.55, is rational, so A
Step-by-step explanation:
The reason being this is because, 2.55 is a terminating decimal meaning that the decimal place does not go on forever.
Sara's classification is not correct because the sum is a rational number.
What is an irrational number?Irrational numbers are real numbers that cannot be expressed in fractions.
First, we can find the sum
i.e 1.3+1.25 = 2.55
Here, 2.55 is a rational number.
51/20 = 2.55
Since the sum is a rational number Sarah is not correct.
