ΔADE ~ ΔABC, so

AD : AB = (x + 1) : (4x - 6)

Note AB = 2 AD, so

4x - 6 = 2(x + 1)

4x - 6 = 2x + 2

2x = 8

x = 4

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the length be 9x, then the width is 4x

perimeter = 2(9x + 4x) = 2(13x) = 26x = 78, so x = 78/26 = 3

So

the length = 9x = 9(3) = 27 mm

the width = 4x = 4*3 = 12 mm.

Answer:

The interval of decrease is 0 ≤ x ≤ 1.25

Step-by-step explanation:

First, we have to find the point where it changes from increasing to decreasing or decreasing to increasing.

The graph shows that there is a decrease before 1.25 h, and it increases after 1.25 h also.

We can further prove that 1.25 is the point of change when we enter 1.25 in place of t in the given equation

d(1.25) = 40|1.25 - 1.25| = 0

We see that the graph is decreasing before 1.25, so the interval will have to end at 1.25.

We also see that there is no increase before 1.25, so we can make the interval begin at 0

The minimum amount the students are A) $125 will need to save every month in order to pay for the first year of tuition.

What are the minimum students?

Assuming that the student will save the same amount every month for three years to cover the first year of tuition, we need to find the monthly savings needed to accumulate $4,500 in 36 months.

$4,500 ÷ 36 months = $125

Therefore, the student needs to save $125 every month to pay for the first year of tuition in three years.

So, the answer is A) $125.

What is tution?

Tuition refers to the fee charged by educational institutions, such as schools, colleges, and universities, for the instruction and education they provide. It is the cost that students must pay in order to attend and receive an education from these institutions. Tuition fees vary depending on the type of institution, the program of study, and the location. Some institutions may also offer financial aid or scholarships to help students pay for their tuition.

As the name implies, the pythagorean identity uses the pythagorean theorem for right triangles. The 1 on the right hand side is the length of the hypotenuse, which is the radius of the unit circle.

By mutually exclusive, it means that there are no overlaps between the two events. This means that the probability of the P(A U B) or P(A or B) is simply the sum of the two probabilities.

P(A or B) = 0.40+0.30=0.70

Therefore the answer would be D 0.70

I hope this helped and if you have any more questions to this element please ask!

The value of P(A or B) with A and B are mutually exclusive events is 0.70. Therefore, option D is the correct answer.

Mutually exclusive is a statistical term describing two or more events that cannot happen simultaneously. It is commonly used to describe a situation where the occurrence of one outcome supersedes the other.

Give that, P(A)=0.40 and P(B)=0.30.

We know that, P(A or B) = P(A)+P(B)

= 0.40+0.30

= 0.70

Therefore, option D is the correct answer.

Answer:

Correct option is B)

n(AUB)=n(A)+n(B)−n(A∩B)

     =75+45−35

number of students owing car or stereos=85

number of students neither car nor stereo =100−85=15

The number of students who do not own either a car or an iPod is 25.

Union of two given sets is the smallest set which contains all the elements of both the sets.

Intersection of two given sets is the largest set which contains all the elements that are common to both the sets

The union of two sets is given by

n(A∪B) = n(A) + n(B) -n(A∩B)

Where,

A and B are the two sets.

∪ is the union

∩ is the intersection.

According to the given question.

Total number of students in a college = 100

Total number of students who own iPods, n(A) = 55

Total number of students who own cars, n(B) = 25

Number of students who own both cars and iPods, n(A∩B) = 5

Therefore,

The number of students who own cars or iPods is given by

n(A∪B) = n(A) + n(B) - n(A∩B)

⇒n(A∩B) = 55 + 25 - 5

⇒ n(A∪B) = 75

So, the number of students who do not own either a car or an iPod

= 100 - 75

= 25

Hence, the number of students who do not own either a car or an iPod is 25.

Answer:

Step-by-step explanation:

(x - 2)² (x - 2/5) = 0

5(x - 2)² (x - 2/5) = 0

(x - 2)² * 5(x - 2/5) = 0

(x - 2)² (5x - 2) = 0

(x² - 4x + 4)(5x - 2) = 0

5x³ - 20x² + 20x - 2x² + 8x - 8 = 0

5x³ - 22x² + 28x - 8 = 0

Distributive Property is the act of taking one number or variable and multiplying it into a set interval. We always distribute before anything else in the equation (PEMDAS) For example:

4 (3 - 5)

The act of distribution is multiplying the 4 by all variables inside the following parenthesis. This act would make the equation turn into this:

4 (3 - 5) → (4 x 3) - (4 x 5) → (12 - 20) → -6

This means out of the option choices the only feasible answer would be:

Step-by-step explanation:

Rolling two fair dice more than doubles the difficulty of calculating probabilities. This is because rolling one die is independent of rolling a second one. One roll has no effect on the other. When dealing with independent events we use the multiplication rule. The use of a tree diagram demonstrates that there are 6 x 6 = 36 possible outcomes from rolling two dice.

Answer:

11/36

Step-by-step explanation:

There are 36 possible outcomes from rolling 2 dice because the first die has 6 possible outcomes and so does the second.

If the first dice is a 2, the second die can be from 1 to 6. So, there are 6 ways that one dice can show a 2. Since it can happen to both die, you double it to be 12.

But, we have counted the roll of 2,2 twice. So we minus 1 possibility.

Thus, there are 11 ways to roll at least one 2 and 36 possibilities.

Step-by-step explanation:

f(36)=3700(1−0.06) ^36/5

The value of the quantity after 36 minutes is approximately 3701.5.

percentage, a relative value indicating hundredth parts of any quantity.

We can use the formula for exponential decay to find the value of the quantity after 36 minutes:

[tex]A =A_{0} e^-^r^t[/tex]

where:

A₀ = initial value = 3700

r = decay rate per unit time = 6% = 0.06

t = time in minutes

We want to find A after 36 minutes, so:

t = 36

Substituting these values into the formula, we get:

[tex]A = 3700e^(^-^0^.^0^6^\times^ 3^6^/^5)[/tex]

A=3701.5

Therefore, the value of the quantity after 36 minutes is approximately 3701.5.
