EXPLAIN how your answer to #17 is correct. Include SHOWN WORK in your answer
Please help me I have no clue what to do
Answer:
D
Step-by-step explanation:
The interquartile range IQR = Q₃ - Q₁ = 13. The most commonly accepted definition of an outlier is any value greater than Q₃ + 1.5 (IQR) = 110.5 or less than Q₁ - 1.5 (IQR) = 58.5. Looking at the minimum and maximum values, we see that there are no outliers on the lower end, and at least one outlier on the upper end.
Positive numbers must have the positive sign (+) in front of them.
True False
Answer:
False
Step-by-step explanation:
If a number has no sign, it usually means that it is a positive number. Any numbers greater than zero are described as positive numbers. Usually, we don’t put a plus sign in front of positive numbers because the general understanding is that numbers without a sign are positive.

My notes for rhombuses are: All sides are congruent. Diagonals are perpendicular. Diagonals are angle bisectors.
Answer:
∠BAC = 122°
Step-by-step explanation:
From your notes, you know that ...
∠APB = 90°
12y° = 90°
y = 90/12 = 7.5
Then angle ACP is ...
∠ACP = (4y -1)° = (4(7.5) -1)° = 29°
Angle BAC is the ape.x angle of isosceles triangle BAC, whose base angles are 29°. Hence, ...
∠BAC = 180° -2(29°)
∠BAC = 122°

Westmoreland, CA is 157 feet below sea level. Dallas, TX is 430 feet ABOVE sea level. What is the distance between the two cities?
West Moreland is -157 ( below sea level would be a negative value)
Dallas is 430 above
-157 to sea level is 157 feet
Sea level to 430 is 430 feet
Total distance = 157 + 430 = 587 feet.
Answer:
587 feet
Westmoreland is 157 feet below the sea level.
This is a negative number, so add 157 to get to 0.
Dallas is 430 above sea level.
Add 430 and 157. You get 587.
Hope it helps!

In a petri dish, a certain type of bacterium doubles in number every 40 minutes.
There were originally 64 or 2 to the 6th power, bacteria in the dish. After 120 minutes, the number of bacteria has doubled 3 times, multiplying by 2 to the 3rd power
Now the population of bacteria is is 2 to the 6th power times 2 to the 3rd power. Expressed as a power, how many bacteria are in the petri dish after 120 minutes?
A. 2 to the 9th power
B. 2 to the 18th power
C.4 to the 9th power
D. 2 to the 3rd power
Answer: i dont bs , its 2 to the 9th power. i just got %100 on this quiz. 1.3.5 math
Step-by-step explanation:
There are 2 to the 9th power bacteria are in the petri dish after 120 minutes.
Thus, option (A) is correct.
After 120 minutes, the number of bacteria has doubled 3 times, multiplying by 2 to the 3rd power.
Initially, there were 64 bacteria which is equal to [tex]2^6[/tex].
After the first doubling,
= [tex]2^6 * 2^3[/tex]
= [tex]2^9.[/tex]
After the second doubling, the number becomes
= [tex]2^9 * 2^3 \\[/tex]
[tex]= 2^{12[/tex]
After the third doubling, the number becomes
= [tex]2^{12} * 2^3[/tex]
= [tex]2^{15[/tex].
So, after 120 minutes, there are [tex]2^9[/tex] bacteria in the petri dish.
Thus, option (A) is correct.

SIMPLE
Hello! :)
2(3x − 5) + 5 = 5x + 13 Simplify both sides of the equation
(2)(3x) + (2)(−5) + 5 = 5x + 13 Distribute
6x + −10 + 5 = 5x + 13
(6x) + (−10 + 5) = 5x + 13 Combine like terms
6x + −5 = 5x + 13
6x − 5 = 5x + 13
6x − 5 − 5x = 5x + 13 − 5x Subtract 5x from both sides
x − 5 = 13
x − 5 + 5 = 13 + 5 Add 5 to both sides
x = 18 (ANSWER)
