Solve to find the value for x in the linear equation: 36-4x + 5) = 12
CIE
1 Use the distributive property:
2 Use the subtraction property of equality
3. Division property of equality:
3(-4x) + 3(5) = 12
-12x + 15 = 12
- 12x + 15 - 15 = 12 - 15
-12x = -3
Intro
Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given expression:
3(-4x + 5) = 12
To solve for x;
Use the distributive property to open the parentheses;
3(-4x) + 3(5) = 12
-12x + 15 = 12
then, add -15 to both sides;
-12x + 15 + (-15) = 12 + (-15)
-12x = -3
divide both sides by -12;
[tex]\frac{-12x}{-12}[/tex] = [tex]\frac{-3}{-12}[/tex]
x = [tex]\frac{1}{4}[/tex]

Function k is a continuous quadratic function that includes the ordered pairs shown in the table.
Over which interval of the domain is the function increasing?
i didnt mean to click B btw
Answer:
B
Step-by-step explanation:
It appears to be B because this quadratic function faces down (-ax^2) and the vertex or highest point of this function is when x=1. Thus, the interval of the domain that the function increases must be from negative infinity to 1, giving the answer B.

How do you write, 24.23 as a mixed number in simplest form?
Answer:
24 23/100
Step-by-step explanation:
I think this is the answer.
9514 1404 393
Answer:
24 23/100
Step-by-step explanation:
"Twenty-three hundredths," or 23/100, is a fraction that cannot be reduced. The mixed number version is ...
24 23/100
_____
Additional comment
You start with a denominator that corresponds to the place value of the least-significant digit. Here, that's hundredths, so the fraction you start with is some number of hundredths. Then you reduce the fraction if possible, by canceling all factors of 2 or 5 that you can.
Had it been 23.24, you would start with 23 24/100 and cancel a factor of 4 from numerator and denominator: 23 6/25.
Q. What is the equation by looking at this graph?
Answer:
y=x+2
Step-by-step explanation:
slope is 1
y-int is +2
Answer:
y = 3 + 1/1
Step-by-step explanation:
First, the line passes the y-intercept at 3, so we have y = 3. But we also need the slope. Because the slope is 1/1 or 2/2, the equation would be this:
y = 3 + 1/1
I hope this helps! If you have any questions about how I got this answer please feel free to comment them!

Mrs. Manzo's class has 20 girls and 25 boys. She wants to put them into
identical groups with the same number of boys and girls in each group.
What is the greatest number of groups she can make? *
Answer:
She can make up to 5 groups.
Step-by-step explanation:
We have to find the first divisible number that are divisble for each 20 and 25.
Divisible numbers of 25: 1, 5 Divisible numbers of 20: 1,4, 5, 10

Each of 12 refrigerators of a certain type has been returned to a distributor because of an audible, highpitched, oscillating noise when the refrigerators are running. Suppose that 7 of these refrigerators have a defective compressor and the other 5 have less serious problems. If the refrigerators are examined in random order, let X be the number among the first 6 examined that have a defective compressor. What is the probability that X exceeds its mean valueby more than 1 standard deviation?
Answer:
0.121
Step-by-step explanation:
From the given information:
Let X be a hypergeometric random variable. i.e X [tex]\sim[/tex] h (x;:6,7,12)
To determine the mean and the standard deviation of X of a hypergeometric random variable; we have:
[tex]\mu_x = E(X)[/tex]
[tex]\mu_x = 6 \times \dfrac{7}{12}[/tex]
[tex]\mu_x =1 \times \dfrac{7}{2}[/tex]
[tex]\mu_x =3.5[/tex]
The standard deviation is :
[tex]\sigma _x = \sqrt{(\dfrac{12-6}{12-1}) \times 6 \times (\dfrac{7}{12})\times (1-\dfrac{7}{12})}[/tex]
[tex]\sigma _x = \sqrt{(\dfrac{6}{11}) \times 6 \times (\dfrac{7}{12})\times (\dfrac{5}{12})}[/tex]
[tex]\sigma _x = \sqrt{\dfrac{35}{44}}[/tex]
[tex]\sigma _x = 0.892[/tex]
However, the inequality for the event showcasing how X exceeds its mean value by more than 1 standard deviation is :
[tex]X \geq \mu_x +\sigma_x[/tex]
[tex]X \geq 3.5 +0.892[/tex]
[tex]X \geq 4.392[/tex]
[tex]X \geq 5[/tex]
∴
[tex]P(X \geq \mu_x + \sigma_x ) = P(X \geq 5)[/tex]
[tex]P(X \geq \mu_x + \sigma_x ) = 0.121[/tex]

A jar contains chocolate chip cookies and Anzac
biscuits. If Jim makes a selection at random from the
jar, he has a probability of selecting an Anzac
biscuit. If there are 10 chocolate chip cookies, how
many Anzac biscuits are there?
Answer:
0.20
Step-by-step explanation:
there are 4 + 6 + 10 = 20 biscuits in the jar
probability of picking a chocolate chip biscuit = 4/20 = 1/5 = 0.20
