16 is 40% of what number
Answer:
40
Step-by-step explanation:
16 is 40 percent that means that :
32 is 80 percent
8 is 20 percent.
32 + 8 is 40 ------ 80 percent+ 20 percent =100 percent
40 is the number whose 40% is 16.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
We need to find the number whose 40% is 16.
Let us consider the number be x.
Convert 40% to the decimal by dividing with 100
40/100=0.4
Now multiply zero point four with x which gives 16
0.4x=16
Divide both sides by 0.4
x=16/0.4
x=40
Hence, 40 is the number whose 40% is 16.

We are given the discrete-time sinusoidal segment {6.2 cos(0.75 pi n + 1), n = 0, . . . , (N - 1)}. For what values of N will the spectrum computed using the DFT have no spectral leakage?
Answer:
the values of N for which there will be no spectral leakage are;
N = Integers multiple by 8
Step-by-step explanation:
Given that;
discrete-time sinusoidal segment x[n] = 6.2cos(0.75πn + 1)
Using DFT to compute the spectrum
The spectral leakage will not be present in the spectrum if the product f₀Td is an integer.
Here, f₀ is sinusoid's frequency and Td is the segment duration
Now we calculate the period of the signal
2π/ω = 2π/0.75π
ω = 2 / 0.75
( × 4 )
ω = 8 / 3
Here, the numerator value is the period of the signal
T₀ = 8
The spectral leakage will not be present in the spectrum if N is the Integer multiple of period T₀.
Therefore, the values of N for which there will be no spectral leakage are;
N = Integers multiple by 8

5(x-3y)-2x=6 and x=3y
Solve the equations please by substitution
Answer for the first equation:
(7, -1)
Step-by-step explanation:
Original Equation: 5(x - 3y) - 2x = 6 When x = 3y
Substitute in the 3y for x:
5(3y - 3y) - 2(3y) = 6
5(0) - 6y = 6
-6y = 6
y = -1
Plug -1 in for y in the original equation:
5(x -3(-1)) - 2x = 6
5(x + 3) - 2x = 6
5x + 15 - 2x = 6
3x + 15 = 6
3x = -9
x = -3
A cook used 6 gal of cooking oil last month. She used 15% less this
month. How much cooking oil did she use this month?
Answer:
100%-15%=85%
She used 85% of the total oil for last month
So 6gallons × 85 ÷ 100 = 5.1 gal

The school band decided to make pizza kits to sell for their fundraiser.
The materials cost them $
1500, and they sold the pizza kits for $8.50 a
kit. The Function below can be used to find the profit p(x), where x is
the nunuer of kits sold.
P(x) = 8.50x- 1500
If the band made a profit of $2920, how many pizza kits were sold?
a. 167 kits
b. 344 kits
C. 402 kits
d. 520 kits
Answer:
520
Step-by-step explanation:
Given that:
Profit function p(x) is :
P(x) = 8.50x- 1500
If the profit made = $2920 ; the number of pizza kits sold is :
Then p(x) = 2920
Putting p(x) = 2920 in the equation :
2920 = 8.50x - 1500
2920 + 1500 = 8.50x
4420 = 8.50x
Divide both sides by 8.50
4420 / 8.50 = 8.50x / 8.50
520 = x
Hence, number of pizza kits sold is 520

The mean balance of all checking accounts at a bank on December 31, 2005, was $900. A random sample of 53 checking accounts taken recently from this bank gave a mean balance of $841 with a standard deviation of $190. Using the 1% significance level, can you conclude that the mean balance of such accounts has decreased during this period
Answer:
Step-by-step explanation:
Given that:
The population mean μ = 900
The sample size n = 53
The sample mean = 841
The standard deviation = 190
The level of significance = 0.01
To test the claim that the mean balance of the accounts has decreased during the period.
The null and the alternative hypothesis can be computed as:
[tex]H_o : \mu \ge 900 \\ \\ H_1 : \mu < 900[/tex]
This is a left-tailed test since the alternative is less than 900
The test statistics can be computed as:
[tex]Z = \dfrac{\overline x - \mu}{\dfrac{s}{\sqrt{n}} }[/tex]
[tex]Z = \dfrac{841 -900}{\dfrac{190}{\sqrt{53}} }[/tex]
[tex]Z = \dfrac{-59}{\dfrac{190}{7.28}}[/tex]
Z = -2.26
The p-value = P(Z < -2.26)
From the z-tables
The p-value = 0.01191
The p-value ≅ 0.012
Decision rule: To reject the null hypothesis if the significance level is > p-value.
We failed to reject the null hypothesis.
Conclusion: Thus, there is insufficient evidence to conclude that such accounts mean balance has decreased during this period.
