Work out the surface area of this cylinder.
12 cm
35 cm

Answers

Answer 1

Answer:

The surface area of this cylinder is 3545 cm²

∵ π =

∴ The lateral area = 24 × × 35.

∴ The area of the base = × (12)² = (144) = 452 cm²

∴ The surface area = 2640 + 2(452 ) = 3545 cm²

∴ The surface area of this cylinder is 3545 cm²

in a grocery store, a $21 case of toilet paper is labeled, “get a 20% discount” what is the discount? what is the sale price of the toilet paper?

Answers

Answer:

$16.8

Step-by-step explanation:

put 20% into decimal form 20/100 = 0.2

0.2 x 21 = $4.2

21-4.2 = $16.8

The Discount will be "$4.2" and the Sale price will be "$16.8".

According to the question,

Labeled case of toilet paper,

$21

Get discount,

20%

or,

0.2

Now,

20% of $21 will be:

= [tex]0.2\times 21[/tex]

= [tex]4.2[/tex] ($) (Discount)

→ The sale price will be:

= [tex]Labeled \ case - Discount[/tex]

By substituting the values, we get

= [tex]21-4.2[/tex]

= [tex]16.8[/tex] ($)

Thus the above approach is right.

[tex]Rate = 58007956.5217[/tex]

Step-by-step explanation:

Solving (c): The rate of change:

In this concept, the formula to use is:

[tex]Rate = \frac{V2 - V1}{t2 - t1}[/tex]

Where

[tex](t1,v1) = (0,62817000)[/tex] ----- In 2004

[tex](t2,v2) = (23,1397000000)[/tex] ------ In 2026

So, we have:

[tex]Rate = \frac{1397000000 - 62817000}{23 - 0}[/tex]

[tex]Rate = \frac{1334183000}{23}[/tex]

[tex]Rate = 58007956.5217[/tex]

In a study of the accuracy of fast food​ drive-through orders, one restaurant had orders that were not accurate among orders observed. Use a significance level to test the claim that the rate of inaccurate orders is equal to​ 10%. Does the accuracy rate appear to be​ acceptable?
Identify the null and alternative hypotheses for this test.

Answers

Answer:Null hypothesis:  

Alternative hypothesis:  

 

 

The p value obtained was a very high value and using the significance level given  we have  so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% of significance the proportion of orders that were not accurate is not significant different from 0.1 or 10% .  

and the accuracy of the test yes is acceptable since the p value obtained is large enough to fail to reject the null hypothesis

Step-by-step explanation:

Data given and notation n  

n=367 represent the random sample taken

X=32 represent the orders that were not accurate

estimated proportion of orders that were not accurate

is the value that we want to test

represent the significance level

Confidence=95% or 0.95

z would represent the statistic (variable of interest)

 

Alternative hypothesis:  

When we conduct a proportion test we need to use the z statisitc, and the is given by:  

(1)  

The One-Sample Proportion Test is used to assess whether a population proportion  is significantly different from a hypothesized value .

Calculate the statistic  

Since we have all the info requires we can replace in formula (1) like this:  

 

Statistical decision  

It's important to refresh the p value method or p value approach . "This methos is about determining "likely" or "unlikely" by determining the probability assuming the null hypothesis were true of observing a more extreme test statistic in the direction of the alternative hypothesis than the one observed". Or in other words is just a method to have an statistical decision to fail to reject or reject the null hypothesis.  

The significance level provided . The next step would be calculate the p value for this test.  

Since is a bilateral test the p value would be:  

 

So the p value obtained was a very high value and using the significance level given  we have  so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% of significance the proportion of orders that were not accurate is not significant different from 0.1 or 10% .

The area of the shaded sector subtending 162° at the center is 180π units².

The option (3) is the correct answer.

What is the sector of a circle?

A sector is the portion of a circle enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger is the major sector.

In the diagram, we are given a circle with a shaded sector:

The radius of the circle (r) = 20 units

The angle subtended by the shaded sector = 162°

To find the area of the shaded sector, we can use the formula:

= [tex]\frac12 \theta r^2[/tex]

Where θ is the angle subtended in radians and r is the radius.

162° = 162° × (π/180°) rad

= 0.9 π rad

area of the shaded sector = (1/2) × 0.9 π × 20² = 180π units²

Hence, the area of the shaded sector subtending 162° at the center is  180π units².
