If DB = 36 and AC = 3x - 3, what is the value of x?

Answers

Answer:

A.) 13

Step-by-step explanation:

Since DB =36, and AC is the same line, then AC = 36. The new equation is 36 = 3x - 3. Do inverse operation. Add 3 to both sides of the equation: 36+3=39 & -3+3=0. New equation is 39=3x. Finally divide. 39/3= 13.

All basketballs at a sporting goods store were marked down 25% during the first week of a sale. During the third week, all remaining basketballs were marked down an additional 30%. If a basketball was originally $22, how much does it cost during the third week?

Answers

Answer:

selling price= $9.9

Step-by-step explanation:

Giving the following information:

During the third week, all remaining basketballs were marked down an additional 30%.

Original price= $22

To calculate the selling price in the third week, we need to use the following formula:

selling price= original price*(1 - markdown)

selling price= 22*(0.45)

selling price= $9.9

Find the angle measures. Justify your responses. Given: a||b, m∠6=128 Find: m∠1,m∠3

Answers

Answer:

Angle 1 = 52

Angle 3 = 52

Step-by-step explanation:

Use the theorems

Line b is a straight line which is 180 degrees.

Angle 5 plus angle 6 need to equal 180

Angle 5 = 180 - 128 = 52

Angle 1 is the same as angle 5 because they are located in the same place on a straight line.

Angle 1 = 52 degrees.

Angle 3 is a vertical angle to angle 1, which means they are identical so angle 3 is also 52 degrees.

8x + 5y > 400

(50, 0) for x-intercept

(0,80) for y-intercept

Step-by-step explanation:

We will let x be the # of tshirts and y be the # of hats.

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)

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.

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.

Answers

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.
