Answer 1

The answer is 45

Explanation:

Every triangle is equal to 180 degrees

We know that there is a right angle so

180-90=90

90/2=45

In manufacturing processes, it is of interest to know with confidence the proportion of defective parts. Suppose that we want to be reasonably certain that less than 4% of a company's widgets are defective. To test this, we obtain a random sample of 250 widgets from a large batch. Each of the 250 widgets is tested for defects, and 6 are determined to be defective, based upon the manufacturer's standards. Using α = 0.01, is this evidence that less than 4% of the company's widgets are defective? State the hypotheses, list and check the conditions, calculate the test statistic, find the p-value, and make a conclusion in a complete sentence related to the scenario.

Answer:

Less than 4% of a company's widgets are defective.

Step-by-step explanation:

In this case we want to be reasonably certain that less than 4% of a company's widgets are defective.

The significance level of the test is, α = 0.01.

The hypothesis can be defined as follows:

H₀: At least 4% of a company's widgets are defective, i.e. p ≥ 0.04.

Hₐ: Less than 4% of a company's widgets are defective, i.e. p < 0.04.

The information provided is:

n = 250

x = 6

The sample proportion is, [tex]\hat p=\frac{x}{n}=\frac{6}{250}=0.024[/tex]

Compute the test statistic value as follows:

[tex]z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}\\\\=\frac{0.024-0.04}{\sqrt{\frac{0.04(1-0.04)}{250}}}\\\\=-1.29[/tex]

The test statistic value is -1.29.

The decision rule is:

The null hypothesis will be rejected if the p-value of the test is less than the significance level.

Compute the p-value as follows:

[tex]p-value=P(Z<-1.29)=0.0985[/tex]

So,

p-value = 0.0985 > α = 0.01.

The null hypothesis will not be rejected at 1% significance level.

Thus, there is not enough evidence to support the claim.

Conclusion:

Less than 4% of a company's widgets are defective.

Step-by-step explanation:

Step 1: Define systems

2x - y = 9

4x² + 3y² - 2x + y = 16

Step 2: Rewrite systems

2x - y = 9

Subtract 2x on both sides: -y = 9 - 2xDivide -1 on both sides: y = 2x - 9

Step 3: Redefine systems

y = 2x - 9

4x² + 3y² - 2x + y = 16

Step 4: Solve for x

Substitution

Substitute in y: 4x² + 3(2x - 9)² - 2x + (2x - 9) = 16Expand: 4x² + 3(4x² - 36x + 81) - 2x + (2x - 9) = 16Distribute 3: 4x² + 12x² - 108x + 243 - 2x + 2x - 9 = 16Combine like terms: 16x² - 108x + 234 = 16Factor GCF: 2(8x² - 54x + 117) = 16Divide 2 on both sides: 8x² - 54x + 117 = 8Subtract 8 on both sides: 8x² - 54x + 109 = 0Define variables: a = 8, b = -54, c = 109Resubstitute: [tex]x=\frac{54\pm\sqrt{(-54)^2-4(8)(109)} }{2(8)}[/tex]Exponents: [tex]x=\frac{54\pm\sqrt{2916-4(8)(109)} }{2(8)}[/tex]Multiply: [tex]x=\frac{54\pm\sqrt{2916-3488} }{16}[/tex]Subtract: [tex]x=\frac{54\pm\sqrt{-572} }{16}[/tex]

Here we see that we start to delve into imaginary roots. Since on a real number plane, we do not have imaginary roots, there would be no solution to the systems of equations.

Why is 50 miles per hour a unit rate, and 150 miles per 3 hours is n

Answers

Answer:

Step-by-step explanation:

In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1. For example, if 50km is covered in 5.5 hours, the unit rate will be 50km/5.5 hours = 9.09 km/hour.

Answer:

because unit rate means 1 hour not 3 hour.

The inequality is 8x + 5y > 400; the coefficient 8 comes from $8 per tshirt and 5 from $5 per hats.

For x intercept, you let y = 0;

8x + 5(0) = 400;

8x = 400; divide by 8

x = 50 or (50, 0)

For y intercept, you let x = 0;

8(0) + 5y = 400;

5y = 400; divide by 5

y = 80 or (0,80)

Answer:

\frac{30}{104}

Step-by-step explanation:

9 is the number of boys who play football AND wrestle. 18 is the mumber of footballers, and 12 is the number of wrestlers.

18 + 12, or 30, is the number of boys who EITHER play football or wrestle.

The total number of boys playing sports is 104, so 30 out of 104 boys either play football or wrestle.

You can write this in fraction form as [tex]\frac{30}{104}[/tex].

Answer:

39/143 (B)

Step-by-step explanation:

All the boys who play football, wrestle, or both equals 18 + 12 + 9 = 39

All of the boys are the boys who play football, wretle, or both (39) + the number of outlier boys, (104) = 143 boys in total.

There is a probability of 39/143 that a boy will wrestle or football.
