I just multiplied by 2

Answer: 1) 4:1  2) 60/48

Step-by-step explanation:

1.  12: 3 is the same as 12/3 so you can diving both side by 3.

12:3 ÷ 3/3=4/1

2. 30:24 is the same as 30/24 so you can divide both sides by 6 or multiply both sides by 2.

Answer:

it's A, one yard and 20 inches

Step-by-step explanation:

If you convert them all to inches,  a yard and a 20 inches are equal to 56 inches, so you can rule out the 40 inches answer. a yard and a foot are equal to 48 inches, so we can rule out that also. 3 feet is equal to 36 inches, because we know that a foot is equal to 12 inches. so you are left with A. 1 yard and 20 inches.

Answers

Answer:

The probability that exactly half of the colonies will thrive = (1/3) = 0.3333

Step-by-step explanation:

The list of random numbers simulates the out comes of 4 colonies.

Based On the simulation in 6 trails, what is the probability that exactly half of the colonies will thrive?

The probability of an event is given mathematically as the number of elements in the event divided the total number of elements in the sample space.

Noting that the numbers 0 to 6 indicate that a colony thrives and the number 7 to 9 represent that a colony doesn't thrive.

The 6 trials are given as

4285; 3 colonies thrive, 1 doesn't.

6903; 3 colonies thrive, 1 doesn't.

3829; 2 colonies thrive, 2 don't.

7871; 1 colony thrives, 3 don't.

2868; 2 colonies thrive, 2 don't.

5137; 3 colonies thrive, 1 doesn't.

The number of trials where exactly 2 colonies thrive = 2

The total number of trials = 6

The probability that exactly half of the colonies will thrive = (2/6) = (1/3) = 0.3333

In algebra, a polynomial function with one or more variables in which the highest-degree term is of the second degree is known as a quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic.

The general form of the quadratic functions is represented as below:-

y = ax² + bx + c

Where a,b, and c are the constants x and y are variables.

If Kevin wants a 90 average in math after 5 tests and his first 4 tests are 76, 92, 89 and 97 what does he need on the fifth test for a 90 average?

Answers

You need to understand that you're solving for the average, which you already know: 90. Since you know the values of the first three exams, and you know what your final value needs to be, just set up the problem like you would any time you're averaging something.
Solving for the average is simple:
Add up all of the exam scores and divide that number by the number of exams you took.
(87 + 88 + 92) / 3 = your average if you didn't count that fourth exam.
Since you know you have that fourth exam, just substitute it into the total value as an unknown, X:
(87 + 88 + 92 + X) / 4 = 90
Now you need to solve for X, the unknown:
87
+
88
+
92
+
X
4
(4) = 90 (4)
Multiplying for four on each side cancels out the fraction.
So now you have:
87 + 88 + 92 + X = 360
This can be simplified as:
267 + X = 360
Negating the 267 on each side will isolate the X value, and give you your final answer:
X = 93
Now that you have an answer, ask yourself, "does it make sense?"
I say that it does, because there were two tests that were below average, and one that was just slightly above average. So, it makes sense that you'd want to have a higher-ish test score on the fourth exam.
Average = sum/count

current count = 4
current sum = 76+92+89+97=354

we need average = 90 = sum/5
so, we need sum = 90*5=450

To get sum 450, he needs to score 450-354=96 on his best test.

Now, (76+92+89+97+96)/5=90

It costs Trevor $50 to have a security system installed in his house. He pays a monthly service fee plus tax of 6% of his monthly bill. After 6 months, Trevor had paid a total of $361.64 for his service fee, taxes, and his initial installation. Trevor’s monthly service fee, not including taxes, is ___.

Answers

Answer:

$49

Step-by-step explanation:

Cost of security system installation = $50

Let the monthly service cost be $x

In 6 month monthly service cost = 6*$x= $6x

tax percentage = 6% of monthly service  cost

hence if monthly service cost is $x

Then Tax value in terms of x is =   6% of  $x  = 6/100 * $x =$ 0.06x

In 6 month, Tax value in terms of x  = 6 * $0.06x = $.36x

_______________________________________________

Therefore total cost incurred by Trevor in 6 month including installation charges =

6 month monthly service cost + Tax value in 6 month + installation cost

Substituting value of 6 month monthly service cost , Tax value in 6 month , installation cost in above expression we have

Therefore total cost incurred by Trevor in 6 month including installation charges = $6x+  $0.36x+ $50 = $6.36x + $50

But it is given that After 6 months, Trevor had paid a total of $361.64 for his service fee, taxes, and his initial installation

Therefore total cost incurred by Trevor in 6 month including installation charges  is also equal to $361.64

Hence,

$6.36x + $50 = $361.64

=> $6.36x = $361.64 - $50

=>$6.36x = $311.64

=> x = $311.64/6.36

=> x = 49.

Therefore , Trevor’s monthly service fee, not including taxes is $X which is equal to $49.
