2(4p-8)-4p is simplified to : 4p-16
Answer:
A: 4p-16
Hope this helps!
Step-by-step explanation:
you have to multiply the 2 to 4p and 8 which gives you 8p-16 and then subtract 4p and that give you 4x-16.
3(x – 2) – 2x + 3 = -12

Jabari wants to save $66. He earns
$9 every week, walking his
neighbor's dog for 2 hours. He
saves all of his money. How many
weeks will it take him to save $66?
Answer:
n = 7 1/3 weeks
Step-by-step explanation:
Amount Jabari wants to save = $66
Amount he earns per week = $9
Hours worked per week = 2 hours
How many weeks will it take him to save $66?
Let
n = number of weeks will it take him to save $66
66 = 9n
n = 66/9
n = 7 3/9
n = 7 1/3 weeks
Or
n = 7.33 weeks
In ⊙E, what is AC?
in need of answers
Answer:
d
Step-by-step explanation:
i looked up the answers
The length of AC is 6.4 unit.
The correct option is C.
We have the figure from which we can say that
BD is the diameter which is
= 4.8 + 1.6
= 6.4 unit long.
Now, AC is the chord.
As, the distance between the two opposite point the the surface of circle would be same.
Then, the length of AC = length of BD
Thus, the length of AC is 6.4 unit.

Identify the population and the sample in the situation below:
The coach wants to know which uniform the soccer team wants to wear, but he only asks the starting eleven players.
Question 1 options:
Population: soccer team, Sample: starting eleven player
Population: the starting eleven, Sample: soccer team
Population: the coach, Sample: soccer team
Population: soccer team, Sample: uniforms
Answer:
your answer is, A Population: soccer team, Sample: starting eleven player.
Step-by-step explanation:
I just took the test.
The population and the sample in the situation below is a Soccer team and starting eleven players respectively.
What is sample space?The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive.
Given, The coach wants to know which uniform the soccer team wants to wear, but he only asks the starting eleven players.
Since A population is an entire group that you want to draw conclusions about. A sample is a specific group that you will collect data from. The size of the sample is always less than the total size of the population.
and The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment.
Thus in our case,

Answer:
y=-1/6x
Step-by-step explanation:
To find the answer you can just look at 2 points on the graph and whichever one comes first is (y1,x1) and the next pair is (y2,x2). So to find it we can use (0,0) automatically because the line is crossing through it. We can also use (600,-100) as the second point becasue it is the next farthest away and when we plug the numbers into the slope equation(y2-y1/x2-x1) we get -100-0/600-0 which when simplified is -100/600 or -1/6 so that would be the m in slope-intercept form (y=mx+b) and when you get everything you can find the equation y=-1/6x

37% of Americans say that math is the most important subject in school. In a random sample of 400 Americans, what is the probability that between 40% and 45% will say that math is the most important subject?
Answer:
0.1070 = 10.70% probability that between 40% and 45% will say that math is the most important subject
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
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.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
37% of Americans say that math is the most important subject in school.
This means that [tex]p = 0.37[/tex]
Sample of 400 Americans
This means that [tex]n = 400[/tex]
Mean and standard deviation:
[tex]\mu = p = 0.37[/tex]
[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.37*0.63}{400}} = 0.0241[/tex]
What is the probability that between 40% and 45% will say that math is the most important subject?
This is the pvalue of Z when X = 0.45 subtracted by the pvalue of Z when X = 0.4. So
X = 0.45
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.45 - 0.37}{0.0241}[/tex]
[tex]Z = 3.31[/tex]
[tex]Z = 3.31[/tex] has a pvalue of 0.9995
X = 0.4
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.4 - 0.37}{0.0241}[/tex]
[tex]Z = 1.24[/tex]
[tex]Z = 1.24[/tex] has a pvalue of 0.8925
0.9995 - 0.8925 = 0.1070
0.1070 = 10.70% probability that between 40% and 45% will say that math is the most important subject

A small plane is flying northeast at a speed of 200 mph. A wind blows due west at 28 mph. Find the resultant speed and direction of the plane.
Answer:
The resultant speed = 181.3 mph
The final direction = 38.7° northeast.
Step-by-step explanation:
We need to find the component in the x-direction and in the y-direction of the speed:
For the plane:
[tex] v_{p_{x}} = 200cos(45) = 141.42 [/tex]
[tex] v_{p_{y}} = 200sin(45) = 141.42 [/tex]
For the wind we have:
[tex] v_{w_{x}} = -28 [/tex]
[tex] v_{w_{y}} = 0 [/tex]
Now, the total speed in the x-direction and in the y-direction is:
[tex] V_{x} = v_{p_{x}} + v_{w_{x}} = 141.42 - 28 = 113.42 [/tex]
[tex] V_{y} = v_{p_{y}} + v_{w_{y}} = 141.42 [/tex]
Hence, the resultant speed is:
[tex] V = \sqrt{V_{x}^{2} + V_{y}^{2}} = \sqrt{(113.42)^{2} + (141.42)^{2}} = 181.3 mph [/tex]
Finally, the direction of the plane is:
[tex] tan(\theta) = \frac{V_{y}}{V_{x}} = \frac{141.42}{113.42} = 1.25 [/tex]
[tex] \theta = 51.3 ^{\circ} [/tex]
[tex] \theta = 90 - 51.3 = 38.7 ^{\circ} [/tex]
The plane is moving at 38.7° northeast.
