Answer:
x² + 4x
Step-by-step explanation:
Area of the rectangle = length × width
length = x + 4
width = x
Therefore,
Area = x(x + 4)
Area = x*x + x*4
x² + 4x
Tyrone has 8/9 of a foot of string. He needs to cut pieces of string that are 1/4 of a foot long. How many whole 1/4 foot pieces can he cut from the string he has?
9514 1404 393
Answer:
3
Step-by-step explanation:
You can use your number sense to realize that 8/9 is between 3/4 and 1, so Tyrone can only get 3 whole pieces from his string.
__
If you like, you can do the division ...
(8/9)/(1/4) = (8/9)(4/1) = 32/9 = 3 5/9 . . . . . 3 whole pieces
Or, you can compare decimal values.
1 piece = 0.25 ft
2 pieces = 0.50 ft
3 pieces = 0.75 ft
4 pieces = 1.00 ft
String length = 0.888.... ft (more than 3; less than 4 pieces)

#CarryOnLearningHow are theoretical probability and experimental probability related
Answer:
Experimental probability is the result of an experiment. Theoretical probability is what is expected to happen. Three students tossed a coin 50 times individually.
Step-by-step explanation:
Experimental probability is found through experiments while theoretical probability are not.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
Theoretical probability is the probability that we use normally which describes the percent or probability that an event is likely to happen. This is found using logic.
Experimental probability is the probability that we calculate through the actual experiments that describes the frequency of an event happening. This is found using experiments which are repeated.
They can be same, both of which describes the probability of happening an event.
Hence the experimental probability is found through experiments while theoretical probability are not.

Answer:
The answer is D: only I and II
Step-by-step explanation:
I know for sure this is the correct answer. Hope this helped! Mark me Brainliest!
The true statements are X'Y'Z' becomes the translated image of the triangle XYZ. X'Y'Z' becomes the reflected image of the triangle XYZ.
What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
When XYZ is transformed on a coordinate plane to obtain its congruent image X'Y'Z.
X'Y'Z' becomes the translated image of the triangle XYZ.
X'Y'Z' becomes the reflected image of the triangle XYZ.
X'Y'Z' doesn't become the rotated image of the triangle XYZ.

Given tan theta = -2 and pi/2 < theta < pi; find cos2theta.
a. - 4/3
b.- 4/5
c. 3/4
d. - 3/5
PLEASE HELP ASAP
Answer:
Cos 2theta = -3/5
Step-by-step explanation:
Given that;
tan theta = -2
tan theta = -2/1 = opp/adj
hyp^2 = (-2)^2+1^2
hyp = √4+1
hyp = √5
sin theta = opp/hyp
sin theta = -2/√5
Cos theta = adj/hyp
Cos theta = -2/√5
Cos 2theta = 1-2sin^2 theta
Cos 2theta = 1- 2(-2/√5)^2
Cos 2theta = 1- 2(4/5)
Cos 2theta = 1- 8/5
Cos 2theta = (5-8)/5
Cos 2theta = -3/5

Weight Loss Program Suppose that a weight loss company advertises that people using its program lose an average of 8 pounds the first month, and that the Federal Trade Commission (the main government agency responsible for truth in advertising) is gathering evidence to see if this advertising claim is accurate. If the FTC finds evidence that the average is less than 8 pounds, the agency will file a lawsuit against the company for false advertising. What are the null and alternative hypotheses the FTC should use
Answer:
The null hypothesis is [tex]H_{0}: \mu = 8[/tex], and the alternative hypothesis is [tex]H_{a}: \mu < 8[/tex]
Step-by-step explanation:
At the null hypothesis, we test if the mean is equal to a certain value.
At the alternate hypothesis, we test if the mean is less than, more than, or different of the value tested at the null hypothesis.
Claims to lose an average of 8 pounds the first month
This means that the null hypothesis is [tex]H_{0}: \mu = 8[/tex]
If the FTC finds evidence that the average is less than 8 pounds, the agency will file a lawsuit against the company for false advertising.
FTC tests if the mean is less than 8, so the alternate hypothesis is [tex]H_{a}: \mu < 8[/tex]

-gallon jug of milk every 3 days. At what rate do they drink milk?
Simplify your answer and write it as a proper fraction, mixed number, or whole number
Answer:
4 gallons/1 day
Step-by-step explanation:
What is a rate? A rate is writing a ratio in fraction form. A ratio is the proportion of two things. (ex: for every 1 dog, there are two cats.)
Creating the ratio: For the ratio, there is no given amount of which one needs to come first, but because it is about the milk, I put that first. In the problem it says 12 gallons for 3 days so: 12/3
Simplifying: To simplify, think of the largest factor between the two numbers. If you can't immediately, think of one factor in common and keep simplifying. In this case, 4 is the greatest common factor between these. To simplify, divide both sides by four, and that is your answer: 4: 1

property?

B. (2x2)(x) + (2x2)(-2) + (4x)(x) + (4x)(-2) + (-7)(x) + (-7)(-2)
C. (2x2)(x - 2) + (4x)(x - 2) + (-7)(x - 2)
D. (2x2 + 4x - 7)(x) + (2x2 + 4x - 7)(-2)
Given:
The expression is
[tex](2x^2+4x-7)(x-2)[/tex]
To find:
The expression which is not a correct way to rewrite the given expression.
Solution:
We have,
[tex](2x^2+4x-7)(x-2)[/tex]
Using distributive property, we get
[tex]=(2x^2)(x-2)+(4x)(x-2)+(-7)(x-2)[/tex]
[tex]=(2x^2)(x)+(2x^2)(-2)+(4x)(x)+(4x)(-2)+(-7)(x)+(-7)(-2)[/tex]
Using distributive property the given expression can rewritten as:
[tex]=(2x^2+4x-7)(x)+(2x^2+4x-7)(-2)[/tex]
Only the expression in option A is not a correct way to rewrite the given expression because [tex](2x^2+4x-7)[/tex] is not distributed to [tex](x-2)[/tex] properly.
Therefore, the correct option is A.
