If 50% of the students in your class like chocolate cake, how many students are in your class if 16 students like chocolate cake? hurry!
The required number of students in the class is given as 32, as per the given condition.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Let the number of students in the class be x,
according to the question,
50% of x = 16
x = 16/50%
x = 16/0.5
x = 160/5
x = 32
Thus, the required number of students in the class is given as 32, as per the given condition.

Find the coordinates of the midpoint AB
Segment GH is a mid segment of triangle JKL.Select all of the equations that could be used to find the value of x.
Answer:
A. 2(5x + 2) = 3x + 32
F. ½(3x + 32) = 5x + 2
Step-by-step explanation:
GH = 5x + 2
KL = 3x + 32
Based on the midsegment theorem,
½(KL) = GH
That is:
½(3x + 32) = 5x + 2
Or
2(GH) = KL
That is:
2(5x + 2) = 3x + 32

What are the solutions of the equation x4 - 5x2 - 14 = 0? Use factoring to solve.
x = +/- √7 and x = +/- √2
x = +/- i√7 and x = +/- i √2
x = +/- i √7 and x = +/- √2
x = +/- √7 and x = +/- i √2
Answer:D
Step-by-step explanation:
The solution is: x = +/- √7 and x = +/- i √2 are the solutions of the equation x^4 - 5x^2 - 14 = 0.
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have,
given that,
we have to factorize the equation,
The given equation is
x^4 - 5x^2 - 14 = 0
To factor this expression, we can change variables to make easier to see the solution.
x^4 = y^2
and
x^2 = y
Applying the change, we have
y^2 - 5y - 14 = 0
Now, you can observe that to factor this expression, we just need to find two number which product is 14 and which difference is 5, such numbers are 7 and 2.
y^2 - 5y - 14 = 0
or, (y-7) ( y+2) = 0
However, remember that , y = x^2
so, (x^2-7) ( x^2+2) = 0
Applying the zero property, we have
x = +/- √7
and x = +/- i √2
As you can see, the equation has two real solutions and two complex solutions.
Therefore, the right answer is the last choice.

A figure has been dilated from center 0 by a scale factor of = 7/6 . What scale factor would shrink the dilated figure back to the original size?
Answer:
6/7
Step-by-step explanation:
1 x 7/6 x 6/7 = 1
A scale factor of 6/7 would shrink the dilated figure back to its original size.
To return the dilated figure back to its original size, you would need to use a scale factor that is the reciprocal of the original dilation scale factor. The reciprocal of a fraction is obtained by flipping the numerator and denominator.
Given the original dilation scale factor of 7/6, the scale factor that would shrink the dilated figure back to the original size is:
Reciprocal of 7/6 = (6/7)
So, using a scale factor of 6/7 would shrink the dilated figure back to its original size.

overprotective of his brand new cement mixer,
so each night, he parks it in a storage facility
that is 120 feet long, 45 feet wide, and 45
feet high. What is the facility's volume in cubic
yards?
Answer:
The facility's volume in cubic yards is 9000
Step-by-step explanation:
The volume of the facility is given by the multiplication of it's dimensions.
We want the volume in cubic yards, so the dimensions have to be in yards.
Each feet has a third of an yard. So the dimensions are:
120 feet = 40 yards
45 feet = 15 yards
45 feet = 15 yards
What is the facility's volume in cubic yards?
[tex]V = 40*15*15 = 9000[/tex]
The facility's volume in cubic yards is 9000

13. The programmer at a local public radio station is compiling data on listeners who stream podcasts. An executive for the national broadcaster has communicated that the overall population mean is 20,500 with a standard deviation of 2,180. The local programmer has a sample of 30 podcasts for her station. By the central limit theorem, which interval do about 99.7% of the sample means fall within?
A. 20,102 and 20,898
B. 20,282 and 20,718
C. 19,306 and 21,694
D. 19,704 and 21,296
Answer:
C. 19,306 and 21,694
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this question, for samples of 30:
Mean: 20,500
Standard deviation: [tex]s = \frac{2180}{\sqrt{30}} = 398[/tex]
99.7% of the sample means fall within 3 standard deviations of the mean, by the Empircal Rule with the Central Limit Theorem:
Lower bound: 20500 - 3*398 = 19,306
Upper bound: 20500 + 3*398 = 21,694
So the correct answer is option C.
Norma Jean makes $25 per hour. She works 35 hours per week. She gets a commission of 15% on her total sales. How much should Norma sell to make $4,500 in a single week?
Norma needs to make sales worth $ _____ to make $4,500.
Answer:
$24,166.67
Step-by-step explanation:
Let carry out the breakdown:
So Norman Jean makes a flat rate of $25 per hour, also she works 35 hours per week.
From the above statement Jean will make => 25 × 35 = $875 in a single week without commission.
For Jean to make $4500 in a week, we derive an equation for this:
875 + x = 4500;
x is the amount of commission Jean has to get in a week to make up to $4500 in that week => x = 4500-875; x = $3625.
Let y be the amount of sales Jean has to make to get a commission of x, we derive the following equation: 0.15 × y = x.
y = x ÷ 0.15 => 3625 ÷ 0.15
y = 24166.67.
So for Jean to meet her target of $4500 in a single week, Jean needs to make a sale worth $24,166.67.

Answer:
x=-3
Step-by-step explanation:
First you must distribute -5 to 2x and -7
so you get
-10x+35+24=89
then you will subtract 35 from both sides and get
-10x+24=54 then you will subtract 24 from each side and get
-10x=30 then you will divide -10 and get
