Answer:

2, 3, 5

Step-by-step explanation:

There is no side-side congruence theorem.

There is also no angle-side-side congruence theorem.

That eliminates choices 1 and 4.

The triangles show side-angle-side-angle as congruent corresponding parts.

Also using the vertical angles at vertex C, you get angle-side-angle.

Answer: choices 2, 3, and 5.

Answer:

x = 1

Step-by-step explanation:

17.25x+3.89=21.14
17.25x=17.25
x = 1

Answer:

The solution to the equation is x = 1

Step-by-step explanation:

Hi,

We need to isolate the term that contains the variable "x", so we will subtract 3.89.

17.25x + 3.89 - 3.89 = 21.14 - 3.89

We obtain:

17.25x = 17.25

Dividing both sides by 17.25:

x = 1

Therefore, the solution to the equation is x = 1.

Good luck!

Answer: 2.5

Step-by-step explanation:

To find a mean, the average, we have to add everything together.

So we add 1 + 4 + 3 + 2, which is equal to 10. The next step to find the average is to divide by the total number of “things” which is the 4 puppeteers.

10/4 is 2.5

Answer: its easy 0 and 4

Step-by-step explanation:

Answer:

2x - y = 2

Step-by-step explanation:

The first thing to do is find the slope of the line. Slope can be found using:

rise/run

you can count up on the graph then count across on the x-axis until you reach a point on the line

If you start on -2, you'll count up 2 then go across 1 to land on point (1,0)

So your slope is 2/1 which is just 2

Another thing to note is that your line intercepts at point (0,-2)

With this information, we can create an equation for the line that is in slope intercept form:

y = mx + b

m = slope

b =y- intercept

y = 2x - 2

HOWEVER, the question asks for this to be in standard form, so we have to get x on the right side of the expression and make sure the first and last values are positive:

y   = 2x - 2

-2x   -2x

-2x + y = -2

     /-1     /-1

2x - y = 2

Answer:

  1 9/11 T/h

Step-by-step explanation:

You want the unit rate in metric tons per hour of removal of 2 1/2 metric tons in 1 3/8 hours.

The unit rate in tons per hour is found by dividing tons by hours:

  (2 1/2 T)/(1 3/8 h) = (5/2 T)/(11/8 h) = (20/8 T)/(11/8 h) = 20/11 T/h

 = 1 9/11 T/h

The unit rate is 20/11 metric tons per hour, or 1 9/11 metric tons per hour.

Height is not an example of a continuous variable.

D) The number of cheeseburgers sold yesterday at a drive-thru is not an example of continuous data.

Here, we have,

Continuous data refers to numerical data that can take on any value within a certain range or interval. It typically involves measurements or quantities that can be expressed as real numbers.

A) The time it takes to cut the grass can be measured in minutes or seconds, and it can take on any value within a range. This is an example of continuous data.

B) The lifetime (in hours) of a flashlight battery is a continuous variable. It can take on any value within a range, such as 5.3 hours, 10.7 hours, or any decimal or fractional value.

C) The weights of dogs in an animal shelter can be measured in pounds or kilograms and can take on any value within a range. This is also an example of continuous data.

D) The number of cheeseburgers sold yesterday at a drive-thru is a discrete variable. It represents a count or a whole number, such as 50 cheeseburgers, 100 cheeseburgers, etc. Discrete data involves distinct values and is not continuous.

Therefore, option D is not an example of continuous data.

The best prediction for the number of times that Leo will get an odd number is 200.

The probability of getting an odd number (1 or 3) is 2/4 = 1/2.

Using the expected value formula, we can predict the number of times that Leo will get an odd number:

Expected number of odd numbers = (probability of getting an odd number) x (total number of trials)

Expected number of odd numbers = (1/2) x (400) = 200

Therefore, the best prediction for the number of times that Leo will get an odd number is 200.

Transformation is \(\frac{\pi}{4}\) units towards right to make g(x) from f(x).

Given the parent function is,

f(x) = cos x

And the transformed function is,

g(x) = cos \((x-\frac{\pi}{4})\)

Now,

f(0) = cos 0 = 1

and

\(g(\frac{\pi}{4})=\cos(\frac{\pi}{4}-\frac{\pi}{4})=\cos0=1\)

So the value of f at 0 is equal to value of g at \(\frac{\pi}{4}\).

So the function f(x) transformed to \(\frac{\pi}{4}\) units towards right to obtain g(x).

In a quadrilateral ABCD, the measure of the length of the quadrilateral CD will be 25.98 cm.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The length of AD will be

tan θ = AB/AD

AD = 12/ tan 35

AD = 17.14 cm

Then the value of the BD will be given by the Pythagoras.

BD² = AB² + AD²

BD² = 12² + 17.14²

BD² = 144 + 239.78

BD² = 437.78

BD = 20.92 cm

Then operate the sine rule in triangle BCD, we have

\(\dfrac{BD}{\sin C} = \dfrac{CD }{\sin B}\\\\\\\dfrac{20.92}{\sin 52} = \dfrac{CD }{\sin 102}\\\\\\CD = \dfrac{20.92 \times \sin 102}{\sin 52}\)

On further solving, the value of CD will be

Answer:A perimeter is the sides of a shape added together.

Step-by-step explanation:

Answer:

The perimeter of a rectangle is the total length of all the sides of the rectangle.

Step-by-step explanation:

The perimeter of a rectangle is the total length of all the sides of the rectangle. We can find the perimeter by adding all four sides of a rectangle. Since opposite sides of a rectangle are always equal, we need to find the dimensions of only two sides to find the perimeter of a rectangle.

If you have a 2 inches by 4 inches rectangle, you would have 2 inches + 4 inches + 2 inches + 4 inches = 12 inches

See attached for a sketch of some of the cross sections.

Each cross section has area equal to the square of the side length, which in turn is the vertical distance between the curve y = √(x + 1) and the x-axis (i.e. the distance between them that is parallel to the y-axis). This distance will be √(x + 1).

If the thickness of each cross section is ∆x, then the volume of each cross section is

∆V = (√(x + 1))² ∆x = (x + 1) ∆x

As we let ∆x approach 0 and take infinitely many such cross sections, the total volume of the solid is given by the definite integral,

\(\displaystyle \int_{-1}^1 (x+1) \, dx = \left(\frac{x^2}2 + x\right) \bigg|_{-1}^1 = \boxed{2} ~~~~ (B)\)

Answer:

The systems of equation for the amount spent are as follows

\(Y= 0.99x+5\)

\(Y= 0.79x+10\)

Step-by-step explanation:

In this problem we are expect to give a model or an equation that represents the amount of money spent per month given a fix subscription amount and a variable fee which is based on extra minutes spent.

let Y represent the amount of money spent in total for the month

The first case:

Subscription =$5

charges per minutes = $0.99

therefore the amount spent can be modeled as

\(Y= 0.99x+5\)

The second case:

Subscription =$10

charges per minutes = $0.79

therefore the amount spent can be modeled as

\(Y= 0.79x+10\)

True. A budget is a numerical representation of an organization's plan for the future.

It is employed to forecast the organization's anticipated earnings and costs for a given timeframe, typically a fiscal year.

This makes it easier for the business to calculate how much cash it will need to pay its bills and how much it may set aside for investments in the future.

The budget aids the business in making plans for unforeseen circumstances like a decline in sales or an increase in expenses.

Using the hypergeometric distribution, it is found that there is a 0.3548 = 35.48% probability that she packs at least one pair of high heels.

The formula is:

\(P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}\)

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

The parameters are:

In this problem, we have that:

The probability that she packs at least one pair of high heels is given by:

\(P(X \geq 1) = 1 - P(X = 0)\)

In which:

\(P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}\)

\(P(X = 0) = h(0,31,2,6) = \frac{C_{6,0}C_{25,2}}{C_{31,2}} = 0.6452\)

Then:

\(P(X \geq 1) = 1 - P(X = 0) = 1 - 0.6452 = 0.3548\)

0.3548 = 35.48% probability that she packs at least one pair of high heels.
