Answer:
[tex]3 {x}^{2} + 20x + 12 \\ 3 {x}^{2} + 18x + 2x + 12 \\ 3x(x + 6) + 2(x + 6) \\( 3x + 2)(x + 6)[/tex]
Answer:
x = -2/3, x = -6
Step-by-step explanation:
Let's solve the problem,
→ 3x² +20x + 12
→ 3x² + (2x + 18x) + 12
→ 3x(x+6) + 2(x+6)
→ (3x+2)(x+6)
→ x = -2/3, x = -6
Thus, solution is -2/3, -6.

A certain car going 60 mph can stop in 180 ft. At what speed is the car traveling if it can stop in 100 ft?
The car is speeding at a rate of 33.3mph
Speed and distance of an objectIf a certain car going 60 mph can stop in 180 ft, then we can express this as:
60mph = 180ftTo determine the speed for a car traveling at 100ft, we will have:
x = 100ftTake the ratio of the expression
60/x = 180/100
180x = 6000
x = 33.3mph
Hence the car is speeding at a rate of 33.3mph

A bank balance is more than $35. Julia wants to write an inequality for the bank balance. Which inequality symbol should she use to match the phrase “more than”?
Plus
Greater-than
Less-than
Times
Answer:
x>35
Step-by-step explanation:
The inequality symbol she should use to match the phrase “more than” is "Greater-than".
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Given that,
A bank balance is more than $35.
Let x represents the bank balance.
So, if the bank balance is more than $35,
x > 35
The symbol used is "greater than".
Hence the symbol used for the given inequality expression is "greater than".

There is a bag filled with 3 blue and 4 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting 2 of the same colour?
There is a bag filled with 3 blue and 4 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting 2 of the same colour?
Using the hypergeometric distribution, it is found that there is a 0.4286 = 42.86% probability of getting 2 of the same colour.
The marbles are chosen without replacement, hence the hypergeometric distribution is used to solve this question.
What is the hypergeometric distribution formula?The formula is:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.N is the size of the population.n is the size of the sample.k is the total number of desired outcomes.In this problem:
There is a total of 3 + 4 = 7 marbles, hence N = 7.Of those, 3 are blue, hence k = 3.2 marbles will be taken, hence n = 2.The probability of getting 2 of the same colour is the sum of P(X = 0), which is both red, with P(X = 2), which is both blue, then:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 0) = h(0,7,2,3) = \frac{C_{3,0}C_{4,2}}{C_{7,2}} = 0.2857[/tex]
[tex]P(X = 2) = h(2,7,2,3) = \frac{C_{3,2}C_{4,0}}{C_{7,2}} = 0.1429[/tex]
Hence:
[tex]p = P(X = 0) + P(X = 2) = 0.2857 + 0.1429 = 0.4286[/tex]
0.4286 = 42.86% probability of getting 2 of the same colour.

Two cards are drawn from a standard deck without replacement. What is the probability that the first card is a heart and the second card is red
Answer:
25/208 or 12.2%
Step-by-step explanation:
P(heart) = 13/52 = 1/4
P(red) = 26/52 = 1/2
because we are not replacing the first card drawn, the deck has 51 cards remaining
P(heart, red) = 1/4 × 25/52
= 25/208 or 12.2%

The correct option is B.
What is a sine function?The sine function in trigonometry is the ratio of the hypotenuse's length to the opposite side's length in a right-angled triangle. To determine a right triangle's unknown angle or sides, utilize the sine function.
Given:
A slide 5.1 m long makes an angle of 35° with the ground.
Let the top of the slide is x meters far above from the ground.
Sin(35°) = Opposite/Hypotenuse
Sin(35°) = x / 5.1
x = (5.1) Sin(35°)
x = 2.92 meters.
Therefore, the distance is 2.92 meters.
