The decision for this test at a .05 level of significance is not enough information to make a decision the correct answer is (d).

To make a decision for a hypothesis test, we compare the obtained test statistic (in this case, z = 1.80) with the critical value(s) based on the chosen level of significance (in this case, α = 0.05).

For a one-sample z test, if the obtained test statistic falls in the rejection region (i.e., beyond the critical value(s)), we reject the null hypothesis. Otherwise, if the obtained test statistic does not fall in the rejection region, we fail to reject the null hypothesis.

Without knowing the critical value(s) corresponding to a significance level of 0.05 and the directionality of the test (one-tailed or two-tailed), we cannot determine the decision for this test. Therefore, the correct answer is (d) There is not enough information to make a decision.

Answer:

B 1/2

Step-by-step explanation:

I looked it up.

But I think it'd be C because there would be 4 aces in the deck, and C has 1/4

Answer: 1/13 is the correct answer.

Step-by-step explanation: You put the total amount of aces, which is four, on the top part of your fraction and the total number of 52 cards on the bottom of your fraction. Since four will divide into both numbers, you simplify 4/52 to get 1/13. 4 divided by four is one. 52 divided by 4 is 13. That is how you get your 1/13 from 4/52. Answer was confirmed correct on the test I took. I hope this helps you! Thanks!

Remember that a segment that connects two points A and B is written as:

AB

Now, assuming that in this case the points B, D, and C are collinear, we can see that C is between B and D.

With this, we can find that BC = 10

Then we can write:

BD = BC + CD

And we know that:

BD = 14

CD = 4

we can replace thest two in the above equation to get:

14 = BC + 4

14 - 4 = BC

10 = BC

We just found that the value of the segment BC is 10.

Answer:

1.

\(C.\\sin(N)=\frac{\sqrt{3} }{2}\)

2.

\(x=82.1\)

3.

x = 18°

Step-by-step explanation:

1. The sine ratio is sin(θ) = opposite/hypotenuse, where θ is the reference angle.  When N is the reference angle, we see that side OP with a measure of 5√3 units is the opposite side and side NP with a measure of 10 units is the hypotenuse.

Thus, we can find plug everything into the sine ratio and simplify:

\(sin(N)=\frac{5\sqrt{3} }{10} \\\\sin(N)=\frac{\sqrt{3} }{2}\)

2. We can use the tangent ratio to solve for x, which is tan (θ) = opposite/adjacent.  If we allow the 75° to be our reference angle, we see that the side measuring x units is the opposite side and the side measuring 22 units is the adjacent side.  Thus, we can plug everything into the ratio and solve for x or the measure of the opposite side:

\(tan(75)=\frac{x}{22}\\ \\22*tan(75)=x\\\\82.10511777=x\\\\82.1=x\)

3. Since we're now solving for an angle, we must using inverse trigonometry.  We can use the inverse of the tangent ratio, whose equation is tan^-1 (opposite/adjacent) = θ.  We see that when the x° is the reference angle, the side measuring 11 units is the opposite and the side measuring 33 units is the adjacent side.  Now we can do the inverse trig to find the measure of x:

\(tan^-^1(\frac{11}{33})=x\\ 18.43494882=x\\18=x\)

Answer: 12 cm

Step-by-step explanation:

\(\mathtt{Using\ the \ pythagorean \ theorem: \\}\)

\(a^2+b^2=c^2, \\\ we\ can\ plug\ in\ values\ for\ a,\ b,\ and\ c\)

\(L=a\ and\ M=b\ and\ N=c\)

Therefore,

\(L^2+35^2=37^2\\L^2+1225=1369\\L^2=144\\\sqrt{L^2} =\sqrt{144} \\L=\pm12\\Taking\ only\ the\ positive\ answer,\ we\ get:\\\large\boxed{L = 12cm}\)

We have: L² + M² = N²

=> L² = N² - M² = 37² - 35² = 144 = 12²

=> L = 12

Answer:

$4,500.00

Step-by-step explanation:

.05(50,000) + .08(75,000-50,000)

2,500 + 2,000

4,500

Answer:

  $4500

Step-by-step explanation:

You want to know the commission on a $75000 sale if it is 5% on the first $50000 and 8% of the amount over $50000.

The amount of commission is found by multiplying the commission rate by the applicable sale amount. For a sale amount x such that x > $50,000, the commission is ...

  C = 0.05(50000) +0.08(x -50000) = 0.08x -0.03(50000)

  C = 0.08x -1500

The commission on a sale of 75000 would be ...

  C = 0.08(75000) -1500 = 6000 -1500 = 4500

Your commission is $4500.

Heather has a total of 51 bills consisting of $1, $5, and $10 bills. The number of $5 bills is three times the number of $10 bills. She has a total of $177 saved for the family vacation.

Let's assume the number of $1 bills is x, the number of $5 bills is 3y (since the number of $5 bills is three times the number of $10 bills), and the number of $10 bills is y. We can set up the following equations based on the given information:

1x + 5(3y) + 10y = 177 (equation representing the total amount saved)

x + 15y + 10y = 177

x + 25y = 177 (equation 1)

We also know that the total number of bills is 51, so:

x + 3y + y = 51

x + 4y = 51 (equation 2)

To solve the system of equations, we can multiply equation 2 by 25 and subtract it from equation 1 to eliminate x:

25x + 100y = 1275

-25x - 100y = -1275

0 = -98

Since the resulting equation is inconsistent, there is no solution that satisfies all the conditions. Therefore, there is no way to determine the exact number of each bill that Heather has.

The integral is ∫ x sec x tan x dx. We can solve it using integration by parts xln|sec(x) + tan(x)| - x + C

We have u = x, dv = sec(x)tan(x)dx, du = dx, and v = ln|sec(x) + tan(x)|.

The integral is then

Integrating the second part we get:

xln|sec(x) + tan(x)| - x + C

The integral is ∫ x sec x tan x dx. We can solve it using integration by parts. We let u = x and dv = sec(x)tan(x)dx. Then, du = dx and v = ln|sec(x) + tan(x)|. So, the integral becomes xln|sec(x) + tan(x)| - ∫ ln|sec(x) + tan(x)| dx. We can integrate the second part to get xln|sec(x) + tan(x)| - x + C.

Yes, when graphing two variables and observing an upward slope as you move from left to right, it indicates a positive relationship between the variables.

As one variable increases, the other variable also tends to increase. This positive correlation can be visually represented by a line that slopes upward in a graph. It implies that there is a direct and proportional relationship between the variables being studied.

But downward-sloping line indicate a negative relationship, where as one variable increases, the other variable tends to decrease. The slope of the line provides insights into the magnitude and direction of the relationship between the variables.

(a) Percentage of problems take less than 300 seconds or 5 minutes =41.77%

(b) 58.23% percent of the problems take more than 300 seconds or 5 minutes to resolve.

(c)The standard deviation of the random variable is 24.49

(b) Takes the technician between 30 seconds to 600 seconds to resolve the problem.

90 seconds = 90/60 = 1.5 minutes

600 seconds =600/60 =  10 minutes

So,

\(\mathrm{x} \sim \mathrm{U}(1.5,10)\\P(x > 5 \min )=?\)

\($$\begin{aligned}& \mathrm{f}(\mathrm{x})=\frac{1}{\mathrm{~b}-\mathrm{a}} ; \mathrm{a} < \mathrm{x} < \mathrm{b} \\& \mathrm{f}(\mathrm{x})=\frac{1}{10-1.5} ; 1.5 < \mathrm{x} < 10 \\& \mathrm{f}(\mathrm{x})=\frac{1}{8.5} \\& \begin{aligned}& \mathrm{P}(\mathrm{X} > 5)=\left(\frac{1}{8.5}\right)(10-5) \\&=\frac{5}{8.5} \\&=0.58823 \\&= 58.23 \%\end{aligned}\end{aligned}$$\)

So, 58.23% percent of the problems take more than 300 seconds or 5 minutes to resolve.

Step-by-step explanation:

Answer:

Sure

Step-by-step explanation:

The units g/cm3 and kg/m3 are both used to express the density of a material, which is a measure of its mass per unit volume. Here's how you can convert g/cm3 to kg/m3: Multiply the density in g/cm3 by a conversion factor of 10^-3. Divide the result by a conversion factor of 100^3.

The conversion between g/cm3 and kg/m3 involves multiplying the density in g/cm3 by a conversion factor that takes into account the differences in units of mass (g vs. kg) and volume (cm3 vs. m3).

For example, let's consider the density of water, which is 1 g/cm3. To convert this density to kg/m3, we multiply by 10^-3 to get 0.001 kg/g. Then, we divide by 100^3 to get the final result: 1 g/cm3 * 10^-3 kg/g / 100^3 cm^3/m^3 = 0.001 kg/g * 1/10^9 cm^3/m^3 = 0.001/10^9 kg/m^3 = 1 kg/m^3.This is how you can convert g/cm3 to kg/m3.
