3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.

Open circle is a term used for numbers that are less than (<) or greater than (>). On the other hand, Closed circle is used for numbers that are less than or equal to (≤ ) and greater than or equal to (≥).

Here, we are given four inequalities, let us check them one by one-

A. h + 6 > -3h + 12

⇒ 4h > 6

or h > 3/2

Here, we see that there is no equality sign, this means that 3/2 won't be included and hence h + 6 > -3h + 12 would be an open circle inequality.

B. 7 ≥ d/3

⇒ d ≤ 21

Here, we can clearly see the equality sign which means that 21 will be included. Hence, 7 ≥ d/3 would not be graphed with an open circle.

C. 3(x - 2) < 18

x - 2 < 6

x < 8

Here, we see that there is no equality sign, this means that 8 won't be included and hence 3(x - 2) < 18 would be graphed with an open circle.

D. 2y ≤ 14

y ≤ 7

Here, we can clearly see the equality sign which means that 7 will be included. Hence, 2y ≤ 14 would not be graphed with an open circle.

Thus, 3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.

Which of the following equations uses the inverse property of logarithms correctly? A) log2(2^4)=4. B) 2^log2(4)=4. C) 2^log4(2)
Musya8 [376]

Answer:

(A) and (B)

Step-by-step explanation:

The inverse property of Logarithms is

㏒a(a^x) = x or a^loga(x) = x

Using this property we check each option

(A) Log2(2^4) = 4          correct

(B) 2^log2(4) = 4           correct

(C) 2^log 4(2)\neq 4           incorrect ( it equal to \sqrt{2})

(D) log2(4^2)  \neq 2          incorrect  ( it is equal to 4)

(E)  2^log4(4) \neq 4           incorrect ( it is equal to 2)

F) 4^log2(4)\neq4               incorrect ( it is equal to 16)

The Thundering Herd, an amusement park ride, is not open to patrons less than 54" tall. If the mean height of park patrons is 68
just olya [345]

Answer:

Step-by-step explanation:

Let X be the mean height of peak patrons,

Then X is normal with mean = 68 inches and std dev = 12 inches

Whenever x<54, they are not allowed to use the ride.

x=54 means z=

The z for 54" is \frac{54 - 68}{12} =-1.17

From std normal table we find that the area to the left of -1.17 is

0.3790

P(X>54) =1-0.3790

=0.6210=62.10%

P(54<x<68) = 0.5-0.3790 =0.121=12.1%

P(X>68) =0.5%=50%

The orchestra at millard middle school has 120 members,Of these,30% are eighth-grades students.Find the number of 6th and 7th gr
vitfil [10]

Answer:

84

Step-by-step explanation:

Well lets begin by noting that 30% are Grade Eight. That means that 70% will be Grade Six and Seven, but thats not the question, the question is how many people are sixth and seventh grade. As I said before the answer is 84. To find 10% of 120, you shift the decimal point one place to the left and get 12. I earlier said 70% are grade six and seven meaning 70/10=7

All thats left is a simple multiplication problem, 12x7 which gives you 84. To ensure you are correct. 84/7=12 and that promises you a correct answer.

If you do not understand the math I did here reply and I will further explain. For now I hope this helps!

Find the GCF of 18 and 36.<br> Group of answer choices<br><br> 63<br><br> 18<br><br> 36
Karo-lina-s [1.5K]

Answer:

18

Step-by-step explanation:

The GCF (Greatest Common Factor) for 18 and 36 would be 18 because, the GCF of two non-zero integers, x(18) and y(36), is the greatest positive integer m(18) that divides both x(18) and y(36) without any remainder.
