What percent of 300 is 51
Answer:
17
Step-by-step explanation:
300:51*100 =
(300*100):51 =
30000:51 = 588.24
Now we have: 300 is what percent of 51 = 588.24
Question: 300 is what percent of 51?
Percentage solution with steps:
Step 1: We make the assumption that 51 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=51$100%=51.
Step 4: In the same vein, $x\%=300$x%=300.
Step 5: This gives us a pair of simple equations:
$100\%=51(1)$100%=51(1).
$x\%=300(2)$x%=300(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{51}{300}$
100%
x%=
51
300
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{300}{51}$
x%
100%=
300
51
$\Rightarrow x=588.24\%$⇒x=588.24%
Therefore, 17% of 300 is 51
Answer:

I hoped this helped and remember to stay safe!!!What is the value of x in this equation? 4x + 2 – 23(92 + 92x) = 7
Answer:
-707/704
Step-by-step explanation:
4x + 2 - 2116 - 2116x = 7
-2112x = 2121
x = 2121/-2112 = -707/704
Answer:
x= 2121/-2112 = -707/704 = -1.00426136
Step-by-step explanation:
4x + 2 – 23(92 + 92x) = 7
Eliminate the 2 by substracting both side by -24x - 23(92+92x) = 5
2. Discriminate by multiplying -23 with 92 and -23 with 92x
4x - 2116 -2116x = 5
3. Add 2116 both sides to eliminate -2116
4x -2116x = 2121
4. combine 4x-2116x together
-2112x = 2121
5. Divide both sides with -2112
x= 2121/-2112 = -707/704 = -1.00426136
Between 0°C and 30°C, the volume V ( in cubic centimeters) of 1 kg of water at a temperature T is given approximately by the formula: V = 999.87 − 0.06426T + 0.0085043T² − 0.0000679T³ Find the temperature at which water has its maximum density.
Answer:
[tex]T \approx 3.967\,^{\textdegree}C[/tex]
Step-by-step explanation:
The density of water is given by the following definition:
[tex]\rho = \frac{m}{V(T)}[/tex]
[tex]\rho = \frac{1000\,g}{999.870.06426\cdot T + 0.0085043\cdot T^{2}-0.0000679\cdot T^{3}}[/tex]
The density is maximum when volume is minimum, which can be found by First and Second Derivative Tests:
First Derivative
[tex]V' = -0.06426 +0.0170086\cdot T -0.0002037\cdot T^{2}[/tex]
Second Derivative
[tex]V'' = 0.0170086 - 0.0004074\cdot T[/tex]
Critical values from the first derivative are:
[tex]T_{1} \approx 79.531\,^{\textdegree}C[/tex] (absolute maximum) and [tex]T_{2} \approx 3.967\,^{\textdegree}C[/tex] (absolute minimum).
The temperature at which water has its maximum density is:
[tex]T \approx 3.967\,^{\textdegree}C[/tex]

Keith opened an investment account where he is paid 8% annual interest, compounded semi-annually. He wants to have $7,000 in the investment account in 3 years. What is the number of periods for this investment?
Answer:
6 periods
Step-by-step explanation:
The investment is compounded semi-annually which means it is compounded twice in a year. Period of investment is 3 years. So, number of periods compounded is 3 multiplied by 2 that is 6 periods.
Rate would be 8% divided by 2 that is 4%.
Initial investment can be calculated usinf spreadsheet function as =PV(rate,nper, pmt, FV)
Where,
rate is 0.04
nper is 6
pmt is 0
FV is 7,000
So, initial investment is $5,532.20.
It is negative as it is a cash outflow.
Last month, Belinda worked 160 hours at a rate of $10.00 per hour. If her employer retains 9% of her gross salary, is $1,500 a reasonable estimate of her net salary?
We have been given that last month, Belinda worked 160 hours at a rate of $10.00 per hour.
Let us find amount earned by Belinda last month as:
[tex]\text{Amount earned in 160 hours}=\$10\times 160[/tex]
[tex]\text{Amount earned in 160 hours}=\$1600[/tex]
We are also told that Belinda's employer retains 9% of her gross salary. This means that Belinda's net income will be 91% of $1600. [tex](100\%-9\%=91\%)[/tex].
[tex]\text{Belinda's net income would be}=\$1600 \times \frac{91}{100}[/tex]
[tex]\text{Belinda's net income would be}=\$16\times 91[/tex]
[tex]\text{Belinda's net income would be}=\$1456[/tex]
Upon rounding $1456 to nearest hundred, we will get:
[tex]\text{Belinda's net income would be}\approx \$1500[/tex]
Therefore, $1500 is a reasonable estimate of her net salary.
Final answer:
After calculating the gross salary at $1,600 and then determining the tax retained, Belinda's net salary would be $1,456. Hence, $1,500 is not a reasonable estimate for her net salary.
Explanation:
Let's first calculate the gross salary that Belinda earned. She worked for 160 hours at a rate of $10.00 per hour, so her gross salary can be calculated by multiplying the number of work hours by the rate per hour:
Gross Salary = 160 hours * $10.00 per hour = $1,600
The employer retains 9% of her gross salary, so let's find out how much that amounts to:
Tax = 9% of $1,600 = 0.09 * $1,600 = $144
Now, to obtain the net salary, we subtract the tax from the gross salary:
Net Salary = Gross Salary - Tax = $1,600 - $144 = $1,456
Therefore, $1,500 is not a reasonable estimate of her net salary, as the exact calculation shows that her net salary is $1,456.
Mark knows that his yard is 214 times as long as it is wide. Which equation shows the length, in feet, of the fence that goes all the way around the yard if Mark measures the width as w feet?
Answer:
Length in feet is equal to [tex]\frac{2P}{6.5}[/tex], where P is the perimeter
Step-by-step explanation:
Let the width (W) of the yard be "X"
[tex]W = w[/tex]
Then the length(L) of the yard will be
[tex]2\frac{1}{4} * w[/tex]
[tex]L = \frac{9}{4} *w[/tex]
The perimeter of the yard will be equal to the sum of twice the length and width of the yard
Thus,
[tex]P = 2 W + 2L\\[/tex]
Substituting the given values in above equation, we get -
[tex]P = 2 w + 2 (\frac{9}{4})w\\P = 2w + 4.5 w\\P = 6.5w[/tex]
Thus, width in terms of perimeter is equal to
[tex]w = \frac{P}{6.5}[/tex]
Length in feet is equal to [tex]\frac{2P}{6.5}[/tex]

Which of the following is NOT true of using the binomial probability distribution to test claims about a proportion? Choose the correct answer below. A. One requirement of this method is that npgreater than>5 and nqgreater than>5. B. In a left-tailed test, the P-value is the probability of getting x or fewer successes among the n trials. C. In a right-tailed test, the P-value is the probability of getting x or more successes among the n trials. D. This method uses the binomial probability distribution with the P-value method and uses the value of p assumed in the null hypothesis.
Answer:
The correct option is;
D. This method uses the binomial probability distribution with the P-value method ans uses the value of p assumed in the null hypothesis
Step-by-step explanation:
Here we have the binomial probability distribution is used to test claims about a proportion then the requirement is np > 5 and nq >5
In a left-tailed test, the P value is the probability of getting x or fewer successes among n trials while in a right tailed test, the P-value is the probability of getting x or more successes among n trials
However, the P-value where a binomial distribution is used to test a claim about a proportion is derived from the z score of the parameters of the statistic and not from the p assumed in the null hypothesis.
The incorrect statement is option B. A left-tailed test in binomial probability distribution does not correspond to the probability of getting x or fewer successes among n trials.
Explanation:The statement among the given options that is NOT true of using the binomial probability distribution for testing claims about a proportion is option B. A left-tailed test does not entail the probability of getting x or fewer successes in the n trials. Instead, it approximates the probability of observing a value as extreme as the test statistic or even more extreme, which leans to the left or lower end of the distribution. Thus, the P-value in a left-tailed test corresponds to the total probability of the shaded region of the curve that falls to the left of observed value or test statistic. The remainder of the options (A, C, and D) are accurate statements.

A bucket contains five green tennis balls, two yellow tennis balls, six red tennis balls, and eight blue tennis balls. Tony removes for tennis balls, without replacement from the bucket shown. What is the probability that Tony removes one yellow, one green ,one blue,and then one more blue tennis ball?
Answer:
The probability that Tony removes one yellow, one green ,one blue,and then one more blue tennis ball is 0.0039.
Step-by-step explanation:
We are given that a bucket contains five green tennis balls, two yellow tennis balls, six red tennis balls, and eight blue tennis balls.
As we know that, Probability of an event = [tex]\frac{\text{Favorable number of outcomes}}{\text{Total number of outcomes}}[/tex]
Number of green tennis balls = 5
Number of yellow tennis balls = 2
Number of red tennis balls = 6
Number of blue tennis balls = 8
Total number of tennis balls = 5 + 2 + 6 + 8 = 21
{Now it should be notes that Tony removes for tennis balls, without replacement from the bucket means that every time the total number of remaining balls available for selecting will be one less}.
Now, Probability that Tony removes one yellow = [tex]\frac{2}{21}[/tex]
Probability that Tony removes one green = [tex]\frac{5}{20}[/tex]
Probability that Tony removes one blue = [tex]\frac{8}{19}[/tex]
Probability that Tony removes one blue again = [tex]\frac{7}{18}[/tex]

The length of the sides can be determined using the formula,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Length of DE:
Substituting the coordinates D(1,2), E(2,6) in the formula, we get;
[tex]DE=\sqrt{(2-1)^2+(6-2)^2}[/tex]
[tex]DE=\sqrt{(1)^2+(4)^2}[/tex]
[tex]DE=\sqrt{17}[/tex]
Length of EF:
Substituting the coordinates E(2,6), F(6,7) in the formula, we get;
[tex]EF=\sqrt{(6-2)^2+(7-6)^2}[/tex]
[tex]EF=\sqrt{(4)^2+(1)^2}[/tex]
[tex]EF=\sqrt{17}[/tex]
Length of FG:
Substituting the coordinates F(6,7), G(5,3) in the formula, we get;
[tex]FG=\sqrt{(5-6)^2+(3-7)^2}[/tex]
[tex]FG=\sqrt{(-1)^2+(-4)^2}[/tex]
[tex]FG=\sqrt{17}[/tex]
Length of DG:
Substituting the coordinates D(1,2), G(5,3) in the formula, we get;
[tex]DG=\sqrt{(5-1)^2+(3-2)^2}[/tex]
[tex]DG=\sqrt{(4)^2+(1)^2}[/tex]
[tex]DG=\sqrt{17}[/tex]
Perimeter of DEFG:
The perimeter of DEFG can be determined by adding the side lengths DE, EF, FG and DG.
Thus, we have;
[tex]Perimeter=DE+EF+FG+DG[/tex]
Substituting the values, we have;
[tex]Perimeter=\sqrt{17}+\sqrt{17}+\sqrt{17}+\sqrt{17}[/tex]
[tex]Perimeter=4\sqrt{17}[/tex]

Answer:
New Average of New List = 87.5
Step-by-step explanation:
Average is the arithmetic mean (M) of observations.
M = ΣX / N
where ΣX = sum of all observations , N = number of observations
Given : M = 90 ; N = 40
M = ΣX / N
90 = ΣX / 4
ΣX = 90 x 4
ΣX = 360 [ Of Old List of 4 numbers ]
New ΣX of new list of 4th new number = Old ΣX - Old 4th No. + New 4th No.
New ΣX = 360 - 90 + 80
New ΣX = 350
New Average (Mean M) = New ΣX / N
New M = 350 / 4
New M = 87.5

(a) Suppose one house from the city will be selected at random. Use the histogram to estimate the probability that the selected house is valued at less than $500,000. Show your work.
(b) Suppose a random sample of 40 houses are selected from the city. Estimate the probability that the mean value of the 40 houses is less than $500,000. Show your work.
Answer:
a. 0.71
b. 0.9863
Step-by-step explanation:
a. The mean of the distribution is given as $403,000 and the standard deviation is $278,000.
-To estimate the probability that a randomly selected house has a value less than $500,000:
[tex]P(X<500,000)=P(X=0)+P(X=500)\\\\=0.34+0.37\\\\=0.71[/tex]
Thus, the probability that a randomly selected house has a value less than $500,000 is 0.71
b. -since 40 is larger than or equal to 30, we assume normal distribution.
-The probability can therefore be calculated as:
[tex]P(\bar X)=P(z<\frac{\bar X-\mu}{\sigma/\sqrt{n}})\\\\=P(z<\frac{500-403}{278/\sqrt{40}})\\\\=P(z<2.2068)\\\\=0.986336\\\\\approx 0.9863[/tex]
Hence, the probability that the mean value of the 40 houses is less than $500,000 is 0.9863
To estimate the probability that a house is valued less than $500,000, we count the bars below that value on the histogram. To estimate the probability that the mean value of 40 houses is less than $500,000, we use the Central Limit Theorem to calculate the z-score.
Explanation:(a) To estimate the probability that the selected house is valued at less than $500,000, we need to find the area under the histogram below the value of $500,000. Looking at the histogram, we see that there are 3 bars below $500,000. Each bar represents a count of houses, so we add up the counts of those 3 bars. The estimated probability is given by:
Estimated Probability = (Count of houses valued less than $500,000) / (Total count of houses)
(b) To estimate the probability that the mean value of the 40 houses is less than $500,000, we can use the Central Limit Theorem. According to the Central Limit Theorem, the distribution of the sample mean approaches a normal distribution with mean equal to the population mean and standard deviation equal to the population standard deviation divided by the square root of the sample size. We can then calculate the z-score for $500,000 using the formula:
z = (x - mean) / (standard deviation / sqrt(sample size))
Once we have the z-score, we can find the estimated probability using a standard normal distribution table or calculator.

Mekala has an MP3 player called the Jumble. The Jumble randomly selects a song for the user to listen to. Mekala's Jumble has 4 44 techno songs, 2 22 country songs, and 3 33 jazz songs on it. Mekala plans to listen to 270 270270 songs.
Answer:Close to 60 country songs but probably not exactly 60 country songs.
Step-by-step explanation:
Mekala player Jumble has 4 techno songs, 2 country songs, and 3 jazz songs on it.
Represent this songs in ratio format
Ratio of techno songs,to country songs,to jazz songs= 4: 2 : 3
Total number of songs is unknowns ,let it be represented by x
total number of songs is therefore 4 x, 2 x, and 3 x.
Total number of songs that Mekala plans to Listen = 2 70
Then , 4 x + 2 x + 3 x= 270
9 x = 270
Dividing both sides by 9, we get
x = 30
So, Number of techno songs = 4 × 30= 120
Number of country songs = 2 × 30= 60
Number of jazz songs = 3 × 30= 90
