Select the correct answer. which expression shows the factors of 9x2 3x − 2? a. (3x − 1)(3x − 2) b. (3x 1)(3x − 2) c. (3x 2)(3x − 1) d. (9x − 2)(x 1)
Answers
The complete factor of the expression 9x² + 3x - 2 is (3x - 1)(3x + 2)
How to determine the complete factorization?The expression is given as:
9x² + 3x - 2
Expand the equation
9x² + 3x - 2 = 9x² + 6x - 3x - 2
Factorize the expression
9x² + 3x - 2 = 3x(3x + 2) - 1(3x + 2)
Factor out 3x + 2
9x² + 3x - 2 = (3x - 1)(3x + 2)
Hence, the complete factor of the expression 9x² + 3x - 2 is (3x - 1)(3x + 2)

1st option y-5 = 3(x-1)
Step-by-step explanation:
graph shows y intercept of 2
1st option has a y intercept of 2
Answer:
Option 1
Step-by-step explanation:
Clearly, the slope of the line is 3. (As it cannot be negative in this case and it's more vertical so it's not 1/3)
The point slope form is written as :
y - y₁ = m(x - x₁)
Substituting m = 3 :
y - y₁ = 3(x - x₁)
Option 1 is the only option with the value of m as 3.
What is the factor form pls yall I need help lol and put how to solve it
Answers
Answer:
y = -1/2(x - 3)(x - 7)
Step-by-step explanation:
we already have the x intercepts so we can first put those in our equation
y = a(x - 3)(x - 7)
then we can plug in the vertex to find what our a value is
2 = a(5 - 3)(5 - 7)
2 = a(2)(-2)
2 = -4a
a = -1/2
so your equation is
y = -1/2(x - 3)(x - 7)

What is the probability of rolling an odd number or rolling a 2 on a six sided die? *
1/6
5/6
1/3
1/2
2/3
Guaranteed
Answers
Answer: 2/3
Step-by-step explanation:
First, find the probability of rolling an odd number. The odd numbers on a 6-sided die are 1, 3, and 5. This is a probability of 3/6.
Now, find the probability of rolling a 2. There's only one 2 on a die, so the probability is 1/6.
Next, add these together. 3/6 + 1/6 = 4/6. This can be reduced by dividing both the numerator and denominator by 2. This results in a final probability of 2/3.

The volume of a prism is given by ...
V = Bh
where B is the area of the base, and h is the distance between bases.
Here, the base is a triangle, so its area is given by ...
A = 1/2bh
where b is the base of the triangle, and h is the height perpendicular to the base.
__
Using these formulas with the dimensions given, we have ...
B = 1/2(8 yd)(3 yd) = 12 yd²
V = (12 yd²)(6 yd) = 72 yd³
The volume of the triangular prism is 72 cubic yards.

Mai put $4250 in the bank at 4.4% interest compounded annually. How much was in her

A = 4250(1 + 0.044)7 = $5745.03
The required amount in the Mai accounts after 7 years will be $5745.03.
What is compound interest?Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
Amount = principal[1 + r/n]ⁿᵃ
Here,
Principal = 4250, rate = 4.4%, Time = 7 ,
Amount = 4250[1 + 0.044]⁷

Would you choose to use a histogram, a circle graph, or a line graph to
display the data? Explain your choice.
Answers
Answer:
it is more easier to use a histogram and accurate
Answer:
Line graph
Step-by-step explanation:
A line graph is specifically used to display data that changes over time, a line plot uses several points connected by straight lines on an x and y axis.
I wouldn't choose a histogram because a histogram is used to summarize continuous data.
As well as I wouldn't use a circle graph becasue it is often used to show the percentage of of population who gave a certain answer.

Owen owns a small business selling ice-cream. He knows that in the last week 102 customers paid cash, 3 customers used a debit card, and 8 customers used a credit card.
Answers
The probability that the next costumer will pay with a credit card is 0.07.
What is the probability?Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that the next costumer will pay with a credit card = number of customers that paid with a credit card / total number of customers
8 / ( 8 + 3 + 102)

18. A tree casts a 76ft shadow when the sun is at a 41° angle of depression. Find the height of the tree.
Round to the tenths place.
Answers
Answer:
87.36 ft.
Step-by-step explanation:
Angle of depression : 41°
Length of shadow : 76 ft.
Taking the tan ratio (let the height of the tree be 'h') :
tan 41° = 76/h
0.87 = 76/h
h = 76/0.87
h = 87.36 ft.
Answer:
the height of the tree = 87.4 ft (Rounded to the tenths place)
Step-by-step explanation:
the tree form a right angle with the ground
Then , we have a right triangle .
let H be the height of the tree.
[tex]\tan 41=\frac{76}{H}[/tex]
[tex]\Longrightarrow H = \frac{76}{\tan(41)} = 87.427998948797[/tex]

Using conditional probability, the equation that implies that a and b are independent events is P(B|A) = P(B).
What is Conditional Probability?Conditional probability is the probability of one event happening, considering a previous event. The formula is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which:
P(B|A) is the probability of event B happening, given that A happened.[tex]P(A \cap B)[/tex] is the probability of both A and B happening.P(A) is the probability of A happening.If A and B are independent events, we have that:
[tex]P(A \cap B) = P(A)P(B)[/tex].
Then, at the conditional formula:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{P(A)P(B)}{P(A)} = P(B)[/tex]
