Considering that we have the standard deviation for the sample, the t-distribution will be used, and the critical value is t = 2.6682.

In this problem, σ is not​ known, hence we get the standard deviation of the sample from the histogram and the t-distribution is used.

Using a t-distribution calculator, considering a confidence level of 99​% and 56 - 1 = 55 df, the critical value is t = 2.6682.

A rectangle is a 2-dimensional shape having 4 sides. The width of the rectangle is 5x^2 + 4x - 6

A rectangle is a 2-dimensional shape having 4 sides

The formula for calculating the area of the rectangle is given as:

A = lw

Given the following

Area = 5x^3+19x^2+6x-18
Length = x + 3

Using the synthetic division:

           5x^2 + 4x - 6

x + 3 |  5x^3+19x^2+6x-18

           5x^3 + 15x^2

________________________

                     4x^2 + 6x

Answer:

6+8 is 14 and 14/2 is 7.

Step-by-step explanation:

the answer is 7

Answer:

Out of the two sums, B is the closest to the value to 1/2.

Steps for A:

Change 1/3 to 5/15

2+5/15

= 7/15

7/15 as a decimal: 0.46

0.50 - 0.46 = 0.04

Steps for B:

Change 6/7 to 18/21

Change 1/3 to 7/21

18-7/21

= 11/21

11/21 as a decimal: 0.52

0.52 - 0.50 = 0.02

Answer:

Carter's bedroom would cost more to carpet than Carly's because the floor area of the former is about five square feet greater than the floor area of Carly's bedroom.

Step-by-step explanation:

The area of either of these floors is found by multiplying length by width:

A = L*W.

Carly's bedroom is 15.3 ft by 8.7 ft; multiplying, we get A = 133.11 ft^2

Carter's is 14.4 ft by 9.6 ft:  A = 138.24 ft^2

Carter's bedroom area (138.24 ft^2) is about 5 ft^2 larger than Carly's and would thus cost more to carpet.

The correct statement about the data collected by Ms. Pearson is that there is no association between a student's absences and the final average grades.

The equation that represents a linear relationship is: a + bx

Where x represents the rate of increase. Thus, for linear equations, the functiion increases by a constant term.

Answer:

9.4

Step-by-step explanation:

Hey there!

The question is asking us to use the model to find how long it would take for the loan amount to reach 7,000

In order to answer this, we need to make 7,000 equal to the equation:

7000=5000+5000(0.0425t)

Subtract 5000 from both sides

2000=5000(0.0425t)

Now we simplify the RHS

2000 = 212.5t

Now you divide both sides by 212.5 to get t by itself

t=9.41

So it would take 9.4 months for the loan amount to reach 7000

Answer:

An equation for the slope and y-intercept would be y=-3/5x-3

Step-by-step explanation:

Remember the formula for this, y=mx+b, in which the m stands for the slope and the x would be next to the slope always because the slope is ever changing, and the b stands for the y-intercept or in other words, where the line crosses the y-axis not the x-axis.

Answer:

y = -3/5x - 3

Explanation:

The format of slope-intercept is:

[tex]\sf{y = mx + b}[/tex]

Where:

So to write the equation, I just plug the data into y = mx + b:

[tex]\sf{y=-\dfrac{3}{5}x+(-3)}\\\\\sf{y=-\dfrac{3}{5}x-3}[/tex]

Hence, the equation is y = -3/5x - 3.

The two angles shown are vertical angles which men they equal each other:

9n = 8n + 8

Subtract 8n from both sides:

N = 8

->Solution

i) 9n = 8n+8 [ V.O.A. vertically opposite angles ]

or, 9n - 8n = 8

or, n = 8

therefore, value of n is 8

Now,

ii) 9n = 9 X n = 9 X 8 = 72 degrees

iii) 8n + 8 = 8 X 8 + 8 = 64 + 8 = 72 degrees

Answer:

The correct answer is C: [tex]t\leq 58[/tex]

Step-by-step explanation:

In order to solve this problem, start by first creating an inequality to represent the situation above. The price of the hours and the supply fee can't go over $1,500, so you can set the representative inequality as [tex]25t+50\leq 1500[/tex]. Now solve the inequality, and you will get [tex]25t+50\leq 1500[/tex] => [tex]25t\leq 1450[/tex] => [tex]t\leq 58[/tex] hrs. So C is the correct answer.

Answer:

The answer is C.t is less than or equal to 58.

Step-by-step explanation:

Let x = Number of tutoring sessions

Supplies + tutoring cost = total cost

50 + 25x = 1500

Now need to solve:

Subtract 50 from both sides and simplify

50/ + 25x - 50 = 1500 - 50

25x = 1450

Divide both sides by 25 and simplify

25x/25 = 1450/25

Therefore,

[tex]x\leq 58[/tex]

Step-by-step explanation:

155/30 = 5.17

5.17 x 3 = 15.51

It will take the dog approximately 15.5 minutes to lap enough water to consume 155 ounces.

Here, we have to predict how many minutes a dog will lap water to consume 155 ounces per day, we can set up a proportion based on the given information:

1 dog laps water every 3 minutes and gets 30 ounces.

Therefore, in 1 minute, a dog laps 30/3 = 10 ounces.

Now, we want to find out how many minutes it takes for the dog to consume 155 ounces:

Let x be the number of minutes the dog laps water to consume 155 ounces.

Proportion:

(Ounces lapped in x minutes) / (Ounces lapped in 1 minute) = (Total ounces needed) / (Ounces lapped in 1 minute)

(10x) / 10 = 155 / 1

Simplify the equation:

10x = 155

Now, solve for x:

x = 155 / 10

x = 15.5

So, it will take the dog approximately 15.5 minutes to lap enough water to consume 155 ounces.

Answer:

D'=(1,-1)

Step-by-step explanation:

If you dialate by 1/2 then all you have to do, is find half of point D. so point D sits at (2,-2) and half of 2 would be (1,-1).

The dilated coordinates of D(2,-2) = D'(1,-1).

Resizing an item uses a transformation called dilation. Dilation is used to enlarge or shorten the structures. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. The initial form should be stretched or contracted during a dilatation.

From the graph,

we interpreted the coordinates of D (2,-2).

Coordinates are a pair of integers (Cartesian coordinates), or occasionally a letter and a number, that identify a certain place on a grid, often referred to as a coordinate plane.

To find the dilation of transformation

The basic formula to find the scale factor of a dilated figure is:

Scale factor = coordinates of the new shape ÷ coordinates of the original              shape.

That means,

multiply the factor to the coordinates.

D' = (2 x 1/2, -2 x 1/2)

D' = (1, -1)

Therefore, the coordinates after the dilation D' (1,-1).

[tex]a_{16}=26.5[/tex]

Step-by-step explanation:

Arithmetic series:  [tex]a_n=a+(n-1)d[/tex]

Sum of arithmetic series:  [tex]S_n=\dfrac{n}{2}[2a+(n-1)d][/tex]

(where a is the first term and d is the common difference)

Given:

[tex]\implies a_{25}=44.5[/tex]

[tex]\implies a+(25-1)d=44.5[/tex]

[tex]\implies a+24d=44.5[/tex]

[tex]\implies S_{30}=765[/tex]

[tex]\implies \dfrac{30}{2}[2a+(30-1)d]=765[/tex]

[tex]\implies 30a+435d=765[/tex]

Rewrite [tex]a+24d=44.5[/tex] to make a the subject:

[tex]\implies a=44.5-24d[/tex]

Substitute found expression for a into [tex]30a+435d=765[/tex] and solve for d:

[tex]\implies 30(44.5-24d)+435d=765[/tex]

[tex]\implies 1335-285d=765[/tex]

[tex]\implies 285d=570[/tex]

[tex]\implies d=2[/tex]

Substitute found value of d into [tex]a=44.5-24d[/tex] and solve for a:

[tex]\implies a=44.5-24(2)=-3.5[/tex]

Therefore:
