Answer: The answer is "tween".
Step-by-step explanation: One of the first usages of the term "tweens" was in the late 1990s referring to children who are in the liminal space between childhood and adolescence. In other words, these children are in a state of “in between.” The culture of tweens originally emerged as a marketing niche directed at preteen girls.

What is the length,in meters,of VX?
Answer:
C) [tex]\sqrt{90}[/tex]
Step-by-step explanation:
VY = base and leg
XY = height and leg
VX = hypotenuse (c)
VY:
9 - 6 = 3
Solving for VX(c):
a² + b² = c²
3² + 9² = c²
9 + 81 = c²
c² = 90
c = [tex]\sqrt{90}[/tex]
Answer:The answer would be C 90
Step-by-step explanation:
Pythagorean Theorem is what this is on
Answer:
Not sure what the question is but the equation would be
[tex]c^{2} = a^{2} + b^{2}[/tex]

and to find the missing side
784 = 400 + [tex]b^{2}[/tex]
b= 19.6
The missing side would be 19.6
Answer:
19.6

A stone is dropped from a 196-foot platform. Use the formula h=−16t2+v0t+196 to determine how many seconds it will take for the stone to hit the ground. (Since the stone is dropped, v0=0.) Round your answer to the nearest tenth.
The stone will hit the ground after 3.5 seconds.
Given information:
A stone is dropped from a 196-foot platform.
The height of the stone after t seconds is represented by [tex]h=-16t^2+v_0t+196[/tex]
As the stone hits the ground, the height will become zero and the initial velocity [tex]v_0[/tex] is equal to zero as it is dropped.
So, the time after which the stone will hit the ground will be calculated as,
[tex]h=-16t^2+v_0t+196\\0=-16t^2+0t+196\\16t^2=196\\t^2=12.25\\t=3.5[/tex]
Therefore, the stone will hit the ground after 3.5 seconds.

hey can someone please help me i don’t understand this? the question says “find the surface area of the rectangular prism.”
Answer:
170 in^2
Step-by-step explanation:
you have to find the area of each surface of the square
1) the square on the right side:
5x5=25 in^2
there are 2 of these on opposite sides
2)the of the rectangle facing us;
6x5=30in^2 (5 because 5 is the height)
there are 4 of these
3)add up all the areas
25+25+30+30+30+30=170in^2

To simply a rational expression I should
Answer:
Factorize, then divide the common factors.
Step-by-step explanation:
A rational expression is one that involves the division of two polynomials. The two polynomial having the same variable in each expression.
To simplify a rational expression, the first thing to do is to factorize each expression. This would ensure that there exist a common factor between the numerator and denominator.
Then you can divide by the common factor.
The remaining expressions in the quotient would have been reduced to their simplest form.
Last month, Maria purchased a new cell phone for $500. The store manager told her that her new cell phone would depreciate by 70% every 6 months. Maria thinks she will want to replace her phone after a while. What will be the value (V) of her phone if she tries to trade it in after 2 years? Select all that apply.
Answer:
RM 4.05
Step-by-step explanation:
6mnts=70% of 500 is 350, so 150
1 year= 70% of 150 is 105, so 45
1 n half year = 70% of 45 is 31.5, so 13.5
2 years = 70% of 13.5 is 9.45, so Rm 4.05

The radius of a circle is 10 m. Find the circumference to the nearest tenth.
Answer:
[tex] \bf \large 60 \: m[/tex]
Step-by-step explanation:
Given that :The radius of a circle is 10 m.to find :Find the circumference to the nearest tenth.formulas used :circumference = 2 × π × rwhere,π = 22/7
r = 10 m
explanation :⟼ c = 2πr
⟼ c = 2 × 22/7 × 10 m
⟼ c = 2 × 3•14 × 10m
⟼ c = 6•28 × 10 m
⟼ c = 62•8 m
Round to the nearest tenth :⟼ c = 62•8 m
⟼ c = 60 m
∴ circle circumference is 60 m.
What is value of the expression 9x+4y when x= and y=8
Answer: sorry about that Evaluate for y=8
9x+(4)(8)
9x+(4)(8)
=9x+32
Hope this help :D
Answer:
It doesn't say what x is so once you have x all you have to do is insert the numbers in their place, so you will get 9(x) + 4(8). Now multiply 9 by x, then multiply 4 and 8, which is 32. Now add 32 and whatever 9 times x is. Hope this helps!
The brand manager for a brand of toothpaste must plan a campaign designed to increase brand recognition. He wants to first determine the percentage of adults who have heard of the brand. How many adults must he survey in order to be 95% confident that his estimate is within seven percentage points of the true population percentage? Complete parts (a) through (c) below.
a) Assume that nothing is known about the percentage of adults who have heard of the brand,
n= ____________ (Round up to the nearest integer.)
b) Assume that a recent survey suggests that about 81% of adults have heard of the brand.
n= ____________ (Round up to the nearest integer.) Please show work for this one because they change the percentage a lot, so I may have to work this part out myself. Thank you
c) Given that the required sample size is relatively small, cculd he simply survey the adults at the nearest college?
a. No, a sample of students at the nearest college is a cluster sample, not a simple random sample, so it is very possible that the results would not be representative of the population of adults.
b. Yes, a sample of students at the nearest college is a simple random sample, so the resuls should be representative of the population of adults.
c. No, a sample of students at the nearest college is a stratified sample, not a simple random sample, so it is very possible that the results would not be representaive of the population of adults.
d. No, a sample of students at the nearest college is a convenience sample, not a simple randmom sample. so it is very possible that the results would not be representative of the population of adults.
Answer:
Part A; n= 196
Part B: n = 120
Part C:
d. No, a sample of students at the nearest college is a convenience sample, not a simple random sample. so it is very possible that the results would not be representative of the population of adults.
Step-by-step explanation:
Part A;
The sample size n can be calculated by using the formula
p^ ± z∝/2* √pq/n
this implies that
e= z∝/2* √pq/n
where e= ║p-p^║= 0.07
p^= 0.5
q^= 0.5
Putting the values
e= z∝/2* √pq/n
0.07= ± 1.96 √0.5*0.5/n
Squaring both sides
0.0049 = 3.8146*0.25/n
n= 196
Part B:
Given p^= 0.81 and q^= 1-p^= 1-0.81= 0.19
e= 0.07
Using the formula
e= z∝/2* √pq/n
Putting the values
0.07= ± 1.96 √0.81*0.19/n
Squaring both sides
0.0049 = 3.8146*0.1539/n
n= 119.809= 120
Part C:
The sample selected is not a random sample because all the adults who have heard about the brand do not have equal chances of being chosen.
It is convenience sample that is it is chosen at ease from a nearby college.
Use the formula d=r*t to solve this problem.

Liam has learned 31 out of the 50 words on the list for a
spelling bee. What decimal is equivalent to the fraction
of words he has learned?
Answer:
0.62
Step-by-step explanation:
31/50 =62/100 or 0.62
Step-by-step explanation:
Multiply both the numerator and denominator by 2 to get the denominator to 100 and lastly convert it into a decimal.
[tex] \frac{31 \times 2}{50 \times 2} = \frac{62}{100} = 0.62[/tex]
1 and 22 are a linear pair, 2 and 3 are a linear pair, and 2 and 4 are vertical angles Which of the following statements is not true?
a. 1=3
b. 2 = 3
C. m 1 + m 4 = 180
d. m 2 + m 3 = 180
Answer:
<1 = <3
m<1 + m<4 = 180
m 2 + m 3 = 180
Step-by-step explanation:
If <1 and <2 are linear pair, hence <1 + <2 = 180
If <2 and <3 are linear pair, hence <2 + <3 = 180
Since <1, <2 and <3 are linear pair, hence <1 and <3 vertically opposite
<1 and <4 will also be a linear pair since they will lie on the same straight line. Since the sum of angle on a straight line is 180, hence <1 + <4 = 180degrees
The correct options are
<1 = <3
m<1 + m<4 = 180
m 2 + m 3 = 180
A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 22.4 pounds and a standard deviation of 5.8 pounds. Step 1 of 2 : If a sampling distribution is created using samples of the amounts of weight lost by 73 people on this diet, what would be the mean of the sampling distribution of sample means? Round to two decimal places, if necessary.
Answer:
sampling distribution = 22.4
sampling deviation = 0.68
Step-by-step explanation:
Given that :
Mean , μ = 22.4
Standard deviation, σ = 5.8
n = 73
Therefore, the sampling distribution of the mean and the standard deviation is
[tex]$\mu_{\overline x} = 22.4$[/tex]
So, [tex]$\sigma_{\overline x}=\frac{\sigma}{\sqrt n}$[/tex]
[tex]$=\frac{5.8}{\sqrt {73}}$[/tex]
= 0.68
So the sampling distribution of the mean is 22.4
The standard deviation is 0.68
