A certain ceiling is made up of tiles. Every square meter of ceiling requires 10.75
tiles. Fill in the table with the missing values.

Answer:

The answer is 12

Step-by-step explanation:

If there are 36 gallons per 3 min. To find the per min you would divide 36 by 3.

The 1 dollars found near the table by your friend is likely the money for the tickets.

You are selling tickets at a dance. Individual tickets cost $6, and 2 tickets for a couple cost $10. After the dance, you count $1075 and 195 tickets.

let

x = number of individual ticket

y = number of couple tickets = 2x

Therefore, using equation,

2x(10) + 6x = 1075

2x + x = 195

Hence,

20x + 6x  = 1075

3x = 195

x = 195 / 3

x = 65

Hence,

26x = 1075

26(65) = 1690

Therefore, the money on the table is the ticket money because the money is short of the amount of the tickets in dollars.

Answer: x = 11

Step-by-step explanation:

first, i did simple calculations.

4x(2) = 88

that calculates out to:

8x = 88

then, i divided both sides by 8, in order to get x by itself.

8x/8 = 88/8

x = 11

Pitcher holds 75 in³ of liquid, more than enough to completely fill a vase with a 72 in³ rectangular prism shape.

A rectangular prism is a polyhedron in geometry that has two parallel and congruent bases.

It also goes by the name cuboid.

Six faces, each with a rectangle shape and twelve edges, make up a rectangular prism.

So, the volume of the rectangular prism is:

V = h*w*l

Now, insert values as follows:

V = h*w*l

V = 4.5*4*4

V = 72 in³

Pitcher has 75 in³ of water which is more than enough to fill the vase.

Therefore, the pitcher holds 75 in³ of liquid, more than enough to completely fill a vase with a 72 in³ rectangular prism shape.

The total cost for 8 hours of work is $425.

The total cost for 10 hours of work is $525.

The total amount the plumber earns is made up of a fixed charge and a variable charge. A fixed charge is a charge that remains constant regardless of the number of hours the plumber works. The fixed charge is $25. The variable charge is the charge that increases per hours worked. The variable charge is $50 per hour.

Cost = fixed charge + variable charge

C = $25 + $50h

The total cost for 8 hours

$25 + $50(8)

$25 + $400

= $425.

The total cost for 10 hours

$25 + $50(10)

$25 + $500

Answer:

150°

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 12 , then

sum = 180° × 10 = 1800°

the 12 interior angles of a regular polygon are congruent , then

interior angle = 1800° ÷ 12 = 150°

Answer:

\(x + 2 = - 3x\)

\( - 4x = 2\)

\(x = - \frac{1}{2} \)

Answer:

1) The terminal side lies in quadrant 2

2) cosФ = -15/17

3) tanФ = -8/15

Step-by-step explanation:

1) First, we should realize that since sinФ = 8/17, it is positive. Thus, Ф must be in quadrants 1 or 2. And since cosФ is negative, Ф must be in quadrant 2 because cos, sin, and tan are all positive in quadrant 1

2) Next, we must realize that the sides given are a 8-15-17 right triangle. And in this case, since sinФ = 8/17, cosФ should be 15/17. But since cosФ is negative, cosФ = -15/17

3) Lastly, tanФ is opposite/adjacent. Since opposite of Ф is 8 and adjacent of Ф is 15, then tanФ should be 8/15, but since Ф is in quadrant 2, then tanФ is -8/15

a) The probability that the murder was committed with a knife: 0.55

b) The probability that the cook did it, given that the murder was committed with a knife: 0.275

To determine the probability that the murder was committed with a knife, we first need to find the total number of weapons.

The butler has four poison tipped pens, two crowbars and four knives and the cook has three rolling pins and seven knives.

So, the total knives: 4 + 7 = 11

crowbars: 2

poison tipped pens: 4

and rolling pins: 3

So, the total number of weapons: 11 + 2 + 4+ 3 = 20

The probability that the murder was committed with a knife:

p = 11/20

p = 0.55

Now we need to find the probability that the cook did it, given that the murder was committed with a knife.

P = 0.55 × 0.5

P = 0.275

The required probability is 0.275

Null hypothesis (H0): The population variance is equal to the hypothesized variance, i.e., H0: σ² = 225.
Alternative hypothesis (H1): The population variance is not equal to the hypothesized variance, i.e., H1: σ² ≠ 225.

Based on the given information, you want to perform a Chi-Square test with a significance level (α) of 0.01, sample size (n) of 25, and variance (σ²) of 225, using a two-tailed test. Here's the answer with the terms included:

State the hypotheses:

1. Null hypothesis (H0): The population variance is equal to the hypothesized variance, i.e., H0: σ² = 225.
2. Alternative hypothesis (H1): The population variance is not equal to the hypothesized variance, i.e., H1: σ² ≠ 225.

To determine whether to accept or reject the null hypothesis, you would need to calculate the Chi-Square test statistic and compare it to the critical values found in the Chi-Square distribution table for the given α and degrees of freedom (n-1).

With Alpha set to .05, increasing the sample size would not directly reduce the probability of a Type I error. The probability of a Type I error is determined by the significance level (Alpha) and remains constant regardless of the sample size.

However, increasing the sample size can indirectly affect the probability of a Type I error by increasing the statistical power of the test. With a larger sample size, it becomes easier to detect a statistically significant difference between groups, reducing the likelihood of falsely rejecting the null hypothesis (Type I error).

Increasing the sample size generally decreases the probability of a Type II error, which is failing to reject a false null hypothesis. With a larger sample size, the test becomes more sensitive and has a higher likelihood of detecting a true effect if one exists, reducing the likelihood of a Type II error. However, it's important to note that other factors such as the effect size, variability, and statistical power also play a role in determining the probability of a Type II error.

b. The given value is a parameter because the data collected represent a population.

Parameter: A parameter is a numerical value that describes a characteristic of a population. A population refers to the entire group or set of individuals or items we are interested in studying. Parameters are typically unknown because it is often impractical or impossible to collect data from an entire population. Therefore, we estimate parameters using sample statistics.

Statistic: A statistic is a numerical value that describes a characteristic of a sample. A sample represents a subset or a smaller portion of a population. Statistics are calculated based on the data collected from the sample and are used to estimate or make inferences about the unknown parameters of the population.

In statistics, a parameter is a numerical summary measure of a population. In this case, the study was conducted on all 2223 passengers aboard the Titanic, which represents the entire population of interest.

As ΔABC ≅ ΔDEF, Using congruence properties the value of x= 5 and the value of y= 14.

Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them. Two triangles must have the same angles and, as a result, must be congruent if their sides are the same.

Given that ΔABC ≅ ΔDEF, so that

AB ≅ DE

BC ≅ EF

AC ≅ DF

and AB = 8

BC = 19

AC = 14

EF = 4x-1

DE = y-6,

As AB ≅ DE

8 = y - 6

add 6 both sides we get

y = 8 + 6

y = 14

and BC ≅ EF

19 = 4x - 1

Add 1 both sides we get

4x = 19 + 1

4x = 20

divide both sides by 4 we get
