Louis owns a rectangular piece of property with an area of 1 3 4 square miles. The length of the property is 2 1 3 miles. What is the width of the property?
Answers
Answer:
Step-by-step explanation:
Area of the land A - Length * Width
Given
A = 1 3/4 mi²
Length L = 2 1/3 miles
Required
Width of the property
Substitute into the formula;
A = LW
W = A/L
W = 1 3/4/(2 1/3)
W = 7/4 ÷ 7/3
W = 7/4 × 3/7
W = 3/4 miles
Hence the width of the property is 3/4 miles

Hannah purchased three items at the store for $7.05, $8.12, and $3.97. She paid for
her items with a $50 bill. Which most closely estimates the change Hannah should
receive?
Answers
Answer:
She should receive $30.86
Step-by-step explanation:
$7.05 + $8.12 + $3.97 =19.14
50 - 19.14 = 30.86
Using the subtraction method we have found that Hannah will receive the change of $30.86
What is subtraction?Subtraction is an arithmetic operation that represents the operation of removing objects from a collection
Total cost of three items =7.05 + 8.12 + 3.97 =$19.14
She paid $50 bill
Change that Hannah should receive is =50 - 19.14 = $30.86
Hence, change that Hannah should receive is$30.86

Which sequence could be partially defined by the recursive f (n + 1) = f(n) + 2.5 for n > 1?
Answers
Answer:
Step-by-step explanation:
f(n + 1) = f(n) + 2.5
f(1) = -10
f(2) = f(1) + 2.5 = -10 + 2.5 = -7.5
f(3) = f(2) + 2.5 = -7.5 + 2.5 = -5
f(4) = f(3) + 2.5 = -5 + 2.5 = -2.5

An Air Force plane left Paris and flew toward Moscow. A cargo plane left one hour later flying 40 km/h faster in an effort to catch up to it. After four hours the cargo plane finally caught up. What was the Air Force plane's average speed?
(Use box method)
Answers
Their is your answer hope i get a like
Answer:
The plane is traveling at 160 km/h
Step-by-step explanation:
This is because if the first plane is traveling at 160 and flies for 5 hours it'll travel 800 km. then the second plane will have to catch up in 4 hours since it left an hour late, this means traveling at 160 km with an extra 40 km in 4 hours will get it to the first plane at 800 km in the 4 hours given

Let R be a region in the xyâplane and β >0 be a constant. What is the region R that will minimize the value ofintegral(x^2 + y^2 - b^2)?
Answers
Let R be region in the xy-plane and β>0 be the constant. What is the region R that will minimize the value of integral (x² + y² - β²).
i.e.
[tex]\int \int _R (x^2 +y^2 - \beta^2) \ dA[/tex]
Answer:
0
Step-by-step explanation:
Given that:
[tex]\int \int _R (x^2 +y^2 - \beta^2) \ dA[/tex]
where;
R is the region in the xy-plane.
To minimize our double integral, we have to determine the region over which the function we are integrating has a negative value.
x² + y² - β² ≤ 0 ; where β > 0 is a constant
x² + y² ≤ β² is the circle with center (0,0)
Radius "β" because R: x² + y² ≤ β²
The polar coordinates: x = rcosθ and y = rsinθ
x² + y² = r²
⇒ r limits : r = 0 → β
⇒ θ limits : r = 0 → 2π
[tex]\iint_R(x^2+y^2-\beta^2) \ dA =\int\limits ^{2 \pi}_{\theta=0} \int \limits ^{\beta}_{r=0}( \beta^2 -\beta^2) \ rd \ rd\ \theta[/tex]
[tex]\int \int _R (x^2 +y^2 - \beta^2) \ dA[/tex] = 0

Step-by-step explanation:
A manufacturer of running shoes knows that the average lifetime for a particular model of shoes is 15 months. Someone in the research and development division of the shoe company claims to have developed a longer lasting product. This new product was worn by 25 individuals and lasted on average for 17 months. The variability of the original shoe is estimated based on the standard deviation of the new group which is 5.5 months. Is the designer's claim of a better shoe supported by the trial results?
Answers
Answer:
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to show that the designer's claim of a better shoe is supported by the trial results.
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 15 \ months[/tex]
The sample size is n = 25
The sample mean is [tex]\= x = 17 \ months[/tex]
The standard deviation is [tex]s = 5.5 \ months[/tex]
Let assume the level of significance of this test is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o : \mu = 15[/tex]
The alternative hypothesis is [tex]H_a : \mu > 17[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = n -1[/tex]
=> [tex]df = 25 -1[/tex]
=> [tex]df = 24[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{\= x- \mu }{\frac{s}{\sqrt{n} } }[/tex]
=> [tex]t = \frac{ 17 - 15 }{\frac{5.5}{\sqrt{25} } }[/tex]
=> [tex]t = 1.8182[/tex]
Generally from the student t distribution table the probability of obtaining [tex]t = 1.8182[/tex] to the right of the curve at a degree of freedom of [tex]df = 24[/tex] is
[tex]p-value = P(t > 0.18182 ) = 0.4286[/tex]
From the value obtained we see that [tex]p-value > \alpha[/tex] hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to show that the designer's claim of a better shoe is supported by the trial results.
