Answer:
4
Step-by-step explanation:
All you need to do is plug in each value for x & then solve the equation to see if it equals 7. When a number, like 2, is next to an x you multiply the two of them. So when you substitute a number for x, you multiply it by the 2.
2(3)-1= 5
2(4)-1= 7
2(5)-1=9
What’s the missing side length in this right triangle?
Answer:
your correct answer is 15
i just did wrong so the person below me is correct
Step-by-step explanation:
Answer:
A: 15
Step-by-step explanation:
It is asking for the hypotenuse of the triangle. To find this, use pythaogreans theorem.
A^2 + B^2 = C^2
In this case,
9*9 + 12*12 = C*C
81 + 144 = C*C
225 = C*C
Now do the square root of both sides and you get
15 = C. Therefore the missing length is 15.
A coin is Flipped 3 times. What IS the probability that the coin lands heads up once and tails up twice if order does not matter?
Answer:
The probability that the coin lands heads up once and tails up twice is .375, or 3/8.
Step-by-step explanation:
Check the conditions for a binomial distribution problem:
Define success = heads and failure = tails.The number of trials is fixed; n = 3.Each coin flip is independent of the other.Probability p = .5 of getting either heads or tails.We need to use combinations to determine the probability of getting one success (one head) and two failures (two tails).
The combination would be 3 choose 1: [tex]p = {3 \choose 1} (.5)^1(.5)^2[/tex].
There is one success and two failures, denoted by the superscripts above the probability p = .5.
Use a calculator to evaluate and we get:
[tex](3)(.25)(.5) = .375[/tex]The probability that the coin lands heads up once and tails up twice is .375, or 3/8.

Use the associative property
write an equivalent expression.
(5 + 7) + x =
5+(7+x)
Step-by-step explanation:Finding an Equivalent Expression
The associative property of addition states that you can move the terms that are inside the parentheses and still have the expression remain true. So, in the answer above, I moved 5 out of the parentheses and x into the parentheses. No matter the value of x the value of the expression will remain the same
Examples and Proof
Another example of the associative property could be (1+6)+3 = 1+(6+3). To prove this statement we can evaluate each side of the expression.
First, let's do (1+6)+3
(1+6)+3(7)+310Next, let's do 1+(6+3)
1+(6+3)1+(9)10As you can see both of these expressions are the same, thus proving that the associative property works in this situation.

A store uses binary numbers to assign a unique binary sequence to each item in its inventory. What is the minimum number of bits required for each binary sequence if the store has between 75 and 100 items in its inventory?.
Answer:
Introduction:
Binary numbers are used by different departmental stores to keep track of their inventory.
Explanation:
For this the minimum binary numbers should be 8 bits which can represent 256 unique values.
If a store needs to represent its inventory items between 25 to 75, it should use at least 8 bits which can formulate a eight bit number for every item.
Conclusion:
Therefore the correct answer is d. 8

The question:
Divide. give the quotient and remainder. 4374/5
(This is from Aleks)
Answer:
Q: 875 R: 4
Step-by-step explanation:
If you dont like doing long division, try plugging values in usling a calculator! Estimate tht 5*8=40, and then, 5*800 must then equal 4000, which is pretty close to 4374
5*7=35, so the 5*70 must equal 350
5*4 equals 20, so when you add these values up you get...
4000+350+20...
or 4370
and, since 4374-4370 equals 4, your remainder would be 4!

Tia lives at the corner of 4th street and 8th avenue. lei lives at the corner of 12th street and 20th avenue. the fruit market is three-fourths the distance from tia’s home to lei's home. x = (startfraction m over m n endfraction) (x 2 minus x 1) x 1 y = (startfraction m over m n endfraction) (y 2 minus y 1) y 1 where is the fruit market? 6th street and 11th avenue 10th street and 17th avenue 9th street and 15th avenue 8th street and 14th avenue
Applying the distance formula, the distance from from Tia's home to Lei's home = 14.4 units.
What is the Distance Formula?The distance formula helps us to find the distance between two given coordinate points. It is expressed as, [tex]\mathbf{d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} }[/tex].
Tia = (4, 8) = (x1, y1)
Lei = (12, 20) = (x2, y2)
Apply the distance formula to find the distance from Tia's home to Lei's home:
d = √[(12−4)² + (20−8)²]
d = √[(8)² + (12)²]
d = √(64 + 144)
d = √208
d ≈ 14.4 units
