1.Consider a 5-degree-of-freedom t distribution. P (t≤1.05)=0.829.

2. Think about a t distribution with 26 possible degree. P(t>c)=0.05 and c=1.7056

Given that,

We have 2 question

1. Consider a 5-degree-of-freedom t distribution.

We have to find P (t≤1.05) at least three decimal places, round your response.

From t- value cumulative distribution function

Given a t-value and the degrees of freedom, locate the area under the t-distribution from -t to t.

P(t≤1.05)=0.829.

Therefore, P(t≤1.05) is 0.829.

2. Think about a t distribution with 26 possible degree. P(t>c)=0.05.

We have to find c at least three decimal places.

From inverse t-value distribution function

t=invT(0.95,26)=1.7056

Therefore, c is 1.7056

As y varies directly with x, the numerical value of x when y = 55 is 5.

Proportional relationships are relationships between two variables where their ratios are equivalent.

A direct variation equation is a linear equation in two variables.

It is expressed as;

y ∝ x

Hence,

y = k(x)

Where k is proportionality constant.

Given that;

First, we determine the proportionality constant of the direct variation.

y = k(x)

77 = k(7)

Divide both sides by 7

77/7 = k(7)/7

k = 77/7

k = 11

Now, we find the value of x when y = 55

y = k(x)

55 = 11(x)

Divide both sides by 11

55/11 = 11(x)/11

x = 55/11

x = 5

Therefore, the numerical value of x is 5.

Option D)5 is the correct answer.

Answer:

The y-value of the point (4, 8) is (obviously) 8. Since the line has a slope of zero, everywhere on the line will have a y-value of 8. So the equation of the line is y = 8. The x-value can be any number, but the y-value will always be 8

For 47 Go golf and 54 golf game would the cost be the same.

Given that -

Go Golf charges -

Ball and club rental = $2.50

For 1 game =  $4.25  and

Golf Games charges -

Ball and club rental =$3.25

For 2 game =   $8.50

Find out - For how many games would the cost be the same?

Total charges of Go golf per game = $2.50 + $4.25 = $6.75

Total charges of Golf game for 2 games = $3.25 + $8.50  = $11.75

For per game = $11.75 / 2 = $5.875

For Go golf let game = x and

for golf game let game = y

6.75 x = 5.875y

Transformation of the fraction

27/4 x = 47/8 y

After cross multplication

54x = 47y

x/y = 47 / 54

then x = 47

and y = 54.

Hence, The price would be the same for both the 47 and 54 golf games.

Answer:

4h+45=165

Step-by-step explanation:

The cost of the skates does not fluctuate, therefore it always costs $45 no matter how long you use them for.

Answer:

4h + 45 = 165

Step-by-step explanation:

The question was a little hard to understand, but I made some assumptions based off of the answer choices and the information. If any of the assumptions I made sound incorrect, please don't use my answer!

Based off of the question and answer choices, I'm going to assume that Alan paid an initial price of $45 for the skis and then spent 4 hours skiing for an unknown hourly rate. The total amount of money she spent was $165.

Let h represent the hourly rate. Since Alan spent 4 hours skiing, 4 multiplied by h will represent the amount of money Alan paid for her skiing time.

Alan spent a total of $165. This means that the cost of the skis ($45) plus the cost of her ski time (4h) equals $165. This can be represented in this equation:
4h + 45 = 165

The simplified inequality is x > 7.

What is an inequality?

An inequality in mathematics is a relationship that makes a non-equal comparison between two integers or other mathematical expressions. It is most commonly used to compare the sizes of two numbers on a number line. There are multiple notations used to denote various types of inequalities: (i)The symbol a b indicates that an is less than b. (ii)A > b indicates that an is greater than b. In either scenario, a and b are not equal. These are characterized as stringent inequalities because an is either strictly less than or strictly bigger than b. Equivalence is not allowed. In contrast to rigorous inequalities, there are two forms of non-strict inequality relations.

The given inequality -3 < x - 10

or, -3 + 10 < x

or, 7 < x

In other words, the slope of a line is rise over run.

Therefore, the new road the city planner wants to build is perpendicular to the the D street.
