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

Answers

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.

16 is 40% of what number

Answers

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.

I'm pretty sure the answer is 65

Step-by-step explanation:

30+35=65

180-65=115

So the 3rd angle in the triangle is 115°

Then you subtract 115 from 180 and get 65°

So S equals 65°

Step-by-step explanation:

Step 1: Define

2/5(x - 2) = 4x

Step 2: Solve for x

Distribute 2/5:                                  2/5x - 4/5 = 4xSubtract 2/5x on both sides:          -4/5 = 18/5xDivide both sides by 18/5:              -2/9 = xRewrite:                                            x = -2/9

Answer:

x = -2/9

Step-by-step explanation:

Multiply both sides by 5

2(x - 2) = 4x*5

2x - 4 = 20x            Subtract 2x from both sides

-4 = 18x                   Divide by 18

-4/18 = x

x = -2/9

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?

Answers

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

Solve the equations please by substitution

Answers

x= -3 , y=-1
hope this helped !!

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

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

Answers

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
