9x
A. 3. 3x
B. 32.34
O C. 3.32%
D. (3.3)*
E. 3*. 3x
F. 32x
Answer:
The answer would be A. 3.3x
Step-by-step explanation:
3.3x can be broken down as 3.3.x
3.3 equals 9 and the 'x' is multiplied to 9.
Hence, it equals to 9x.
The expressions are equivalent to the 9ˣ is
3²ˣ = 3ˣ . 3ˣ = (3 . 3)ˣ = 9ˣ
Option C, D and F are correct.
What is Expression?

Using the distributive property, an expression equivalent to 48 + 30 is
5 (6 + 8).
(6) (8) + (3) (10).
(3) (16) + (6) (5).
6 (8 + 5).
Answer:
d. 6(8+5)
Step-by-step explanation:
First you distribute the 6 to the 8 which gets you 48 and then you distribute the 6 to the 5 to get 30
so you would get 48+30
therefore, d is true
Answer: (6) (8) + (3) (10) and (3) (16) + (6) (5) and 6 (8 + 5) all of them is the same answer as 48+30=78

Put the word “aware” before or after your answer if your gonna send a link. I would like to know if they are bots. (99% sure they are)
Answer:
B (range)
Step-by-step explanation:
The IQR would actually increase, because the Q1, Q2, and Q3 would get most likely larger. (Or possibly stay the same).
The median would most likely increase, possibly stay the same.
The maximu would stay the same.
The range would decrease, because right now it’s 13, so without the outlier, the minimum value would be closer to the rest of the data.

What is the lateral area of the pyramid
Answer:
43.75 ft²
Step-by-step explanation:
[tex]s_l[/tex] = (l√(w/2)² + h²) + (w√(l/2)² + h²)
l & w become 3.5, and h becomes 6.
[tex]s_l[/tex] = (3.5√(3.5/2)² + 6²) + (3.5√(3.5/2)² + 6²)
Step 1:Because this is a square pyramid, what you see above essentially becomes what you see below.
[tex]s_l[/tex] = 2(3.5√(3.5/2)² + 6²)
Step 2: Divide 3.5 by 2 to get 1.75.
[tex]s_l[/tex] = 2(3.5√1.75² + 6²)
Step 3: Square both 1.75 and 6 to get 3.0625 and 36 respectively.
[tex]s_l[/tex] = 2(3.5√3.0625 + 36)
Step 4: Add 3.0625 and 36 to get 39.0625.
[tex]s_l[/tex] = 2(3.5√39.0625)
Step 5: The square root of 39.0625 is 6.25.
[tex]s_l[/tex] = 2(3.5 * 6.25)
Step 6: Multiply 3.5 by 6.25 to get 21.875.
[tex]s_l[/tex] = 2(21.875)
Step 7: Multiply 2 by 21.875 to get 43.75.
[tex]s_l[/tex] = 43.75 ft²
The lateral area of this pyramid is 43.75 ft².

A spinner marked off in seven equal-sized regions, numbered 1, 2, 3, 4, 5, 6, and 7, is spun twice. Let the random variable X be the nonnegative difference between the numbers of the regions where the pointer stops, and define a probability mass function g(x)=P(X=x). a) State the range of X. b) Write g as a set of ordered pairs. c) Draw a probability distribution as a histogram. d) Find g(5), and explain what this number represents. e) Find μ, and explain what this number represents.
Step-by-step explanation:
To find - a) State the range of X.
b) Write g as a set of ordered pairs.
c) Draw a probability distribution as a histogram.
d) Find g(5), and explain what this number represents.
e) Find μ, and explain what this number represents.
Proof -
a.)
Range of X = { 0, 1, 2, 3, 4, 5, 6 }
b.)
(0, 7/49), (1, 12/49), (2, 10/49), (3, 8/49), (4, 6/49), (5, 4/49), (6, 2/49)
c.)
The graph is as follows :
d.)
The value of g(5) is 6/49
It represents the probability of the difference of the two spins is 5.
e.)
mean, μ = 2.29
It represents the average value of the spins

4/5-2/3 in simplest term
Answer: =2/15
Step-by-step explanation: Hope this help :D
Answer:
2/15
Step-by-step explanation:
4/5 - 2/3
Step 1: Find a common denominator. 5 and 3 don't share any factors other than 1, so multiply them to get 15.
12/15 - 10/15
(12 - 10)/15
Step 2: Subtract 10 from 12 to get 2.
2/15
4/5 - 2/3 simplified is 2/15.
