Answer 1

Answer:

diameter [d]=15cm

radius [r]=7.5cm

slant height be l

and

height be h.

lateral surface area of cone =

πrl=477cm²

l=477/(3.1416*7.5)

l=20.244

now

h=[tex]\sqrt{20.2²-(7.5/2)²}=20cm[/tex]

height=20cm.

Answer 2

LSA of cone = πrl = 477cm²

L = 477/(3.1416 × 7.5)

L = 20.244

Height (h) = √{20.2²-(7.5/2)²}

h = 20cm

Si compraste 0.5 mts. de alambre grueso con un costo de $ 4.00 pesos por metro y 0.4 mts. de alambre delgado con un costo de $5.00 pesos por metro,
¿Cuánto fue el costo total en la compra de los metros de alambre?

Answers

Answer:

El costo total en la compra es $4.00 pesos.

Step-by-step explanation:

El costo total en la compra de los metros de alambre viene dado por la suma de los costos de los metros individuales de los alambres gruesos y delgados:

[tex] C_{t} = C_{g} + C_{d} [/tex]

En donde:

[tex] C_{t} [/tex]: es el costo total

[tex] C_{g} [/tex]: es el costo del alambre grueso

[tex] C_{d} [/tex]: es el costo del alambre delgado

Podemos encontrar el costo de cada alambre multiplicando el valor por la cantidad de metros:

[tex]C_{g} = 0.5 m*\frac{\$ 4.00}{m} = \$2.00[/tex]

[tex]C_{d} = 0.4 m*\frac{\$ 5.00}{m} = \$2.00[/tex]

Entonces, el costo total es:

[tex]C_{t} = 2.00 + 2.00 = \$4.00[/tex]

Por lo tanto, el costo total en la compra es $4.00 pesos.

5x + 3y = 17
-8x - 3y = 9

Answers

Answer:

1)x=−3/5y+17/5  

2)x=−3/8y+−9/8

Step-by-step explanation:

Let's solve for x.

5x+3y=17

Step 1: Add -3y to both sides.

5x+3y+−3y=17+−3y

5x=−3y+17

Step 2: Divide both sides by 5.

5x/5=−3y+17/5

x=−3/5y+17/5

Answer:

x=−3/5y+17/5  

Let's solve for x.

−8x−3y=9

Step 1: Add 3y to both sides.

−8x−3y+3y=9+3y

−8x=3y+9

Step 2: Divide both sides by -8.

−8x/−8=3y+9/−8

x=−3/8y+−9/8

Answer:

x=−3/8y+−9/8

A local dealership provides you with statistics that show the number of each color car they sold last year along with the percentages that those sales represented relative to their inventory for that color car.

For each color, how many cars did the dealership have in its inventory before they started selling them?

Answers

Answer:

red: 20

white: 30

black: 25

silver: 40

other: 12

Step-by-step explanation:

To find the original number of cars per color in the inventory, divide the sold number of cars by the percent of the inventory.

red: 20 = 10/0.5

white: 30 = 21/0.7

black: 25 = 19/0.76

silver: 40 = 10/0.25

other: 12 = 4/0.33

Option D is correct, (3, 1/2) point is a solution to the inequality y <1/3x+1/2.

What is Inequality?

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The given expression is y < 1/3x+1/2

y less than one divided by three times of x plus one divided by two.

Now let us check by plugging each ordered pair.

Now plug in (-2, 1)

1<1/3(-2)+1/2

1<-2/3+1/2

1<-4+3/6

Is false.

Now plug in (-1, 1)

1<-1/3+1/2

Is false.

Now plug in (0, 1/2)

1/2 < 1/2

is false.

Now plug in (3, 1/2)

1/2 < 3(1/3) + 1/2

1/2 < 1 + 1/2 is true.

Hence, (3, 1/2) point is a solution to the inequality y < 1/3x+1/2.

A company hopes to improve customer satisfaction, setting a goal of less than 5% negative comments. A random survey of 850 customers found only 34 with complaints. Does this provide evidence at the 10% significance level that the company has reached its goal of decreasing the percentage of complaints

Answers

Answer:

The p-value of the test is 0.0901 < 0.1, which means that this provides evidence at the 10% significance level that the company has reached its goal of decreasing the percentage of complaints.

Step-by-step explanation:

A company hopes to improve customer satisfaction, setting a goal of less than 5% negative comments.

At the null hypothesis, we test if the proportion of negative comments is of at least 5%, that is:

[tex]H_0: p \geq 0.05[/tex]

At the alternative hypothesis, we test if this proportion is less than 0.05, that is:

[tex]H_1: p < 0.05[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

0.05 is tested at the null hypothesis:

This means that [tex]\mu = 0.05, \sigma = \sqrt{0.05*0.95}[/tex]

A random survey of 850 customers found only 34 with complaints.

This means that [tex]n = 850, X = \frac{34}{850} = 0.04[/tex]

Value of the test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.04 - 0.05}{\frac{\sqrt{0.05*0.95}}{\sqrt{850}}}[/tex]

[tex]z = -1.34[/tex]

P-value of the test and decision:

The p-value of the test is the probability of finding a sample proportion below 0.04, which is the p-value of z = -1.34.

Looking at the z-table, z = -1.34 has a p-value of 0.0901.

The p-value of the test is 0.0901 < 0.1, which means that this provides evidence at the 10% significance level that the company has reached its goal of decreasing the percentage of complaints.

what is the slope of the line that contains the points (-1,2) and (3,3)

Answers

Answer:

B

Step-by-step explanation:

Hi there!

We are given the points (-1,2) and (3,3) and we need to find the slope.

The formula for slope calculated from two points is [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex], where ([tex]x_{1}[/tex],[tex]y_{1}[/tex]) and ([tex]x_{2}[/tex],[tex]y_{2}[/tex]) are points

since we have two points, we can substitute them into the formula, but let's label their values to avoid any confusion

[tex]x_{1}[/tex]=-1

[tex]y_{1}[/tex]=2

[tex]x_{2}[/tex]=3

[tex]y_{2}[/tex]=3

now substitute into the formula (m is the slope); remember: we have a negative number in this, so we'll be subtracting a negative.

m=[tex]\frac{3-2}{3--1}[/tex]

simplify

m=[tex]\frac{3-2}{3+1}[/tex]

m=[tex]\frac{1}{4}[/tex]

so B is your answer

Step-by-step explanation:

Identify and correct error

The error is when the inner and outer terms are multiplied. i.e.

[tex]4x * -8 = -32x[/tex] not 32x

[tex]-3 * 5x = -15x[/tex] not 15x

So, the expression is:

The U.S. Census Bureau conducts a study to determine the time needed to complete the short form. The Bureau surveys 200 people. The sample mean is 8.2 minutes. There is a known standard deviation of 2.2 minutes. The population distribution is assumed to be normal. Which distribution should you use for this problem

Answers

Answer:

The z-distribution should be used for this problem.

Step-by-step explanation:

The population distribution is assumed to be normal. Which distribution to use?

If we have the standard deviation for the sample, we use the t-distribution.

If we use the standard deviation for the population, we use the z-distribution.

There is a known standard deviation of 2.2 minutes.

This means that 2.2 is the population standard deviation, and thus, the z-distribution should be used for this problem.
