The perimeter of a rectangle is 62cm.if the length of the rectangle is 24cm,what is tge width of the rectangle
Answers
Answer:
b= 7
Step-by-step explanation:
here's your solution
=> perimeter of rectangle = 62 cm
=> length = 24 cm
=> let width be (b)
=> perimeter of rectangle = 2(l + b)
=> 2(l + b ) = 62
=> 2(24 + b) = 62
=> 48 +2b = 62
=> 2b = 62 - 48
=> 2b = 14
=> b = 14/2
=> b = 7

On a team, 7 girls and 2 boys scored a total of 46 points. The difference between the number of points scored by the 7 girls and the number of points scored by the
2 boys is 38. Each girl scored the same number of points and each boy scored the same number points. Find the number of points scored by each girl and each
boy
Answers
Answer:
Step-by-step explanation:
let the points scored by a girl=x
points scored by a boy=y
7x+2y=46
7x-2y=38
add
14x=84
x=84/14=6
7×6+2y=46
2y=46-42=4
y=4/2=2
girl scored =6 points

An automobile dealer can sell 12 cars per day at a price of $17,000. He estimates that for each $300 price reduction he can
sell two more cars per day. If each car costs him $14,000, and fixed costs are $1000, what price should he charge to
maximize his profit? [Hint: Let x = the number of $300 price reductions.]
How many cars will he sell at this price?
Answers
Answer:
$ 1100
Step-by-step explanation:
Let p(x) be the price he charges for a car after x price reductions.
Since car costs him $10,000, and fixed costs are $1000
p(x) = 13000-10000-1000-300x = 2000 - 300x
Let q(x) = 12 + 2x the quantity of cars sold after x price reductions.
and the profit he can make are given by:
Profit = R(x) = (12+2x)(13,000 - 10,000 - 1,000 - 300x) dollars.
As you can see, maximizing profit , we have to check where P'(x) = 0
And P''(x)<0.
So we get x = 3.
Replacing the value we get we get 2000 - 300 X 3 = 2000 - 900
= $ 1100

Bear Island 34 43.5 5.33
Goat Island 40 45.9 6.21
Answers
Answer:
The correct solution is "[tex]t=\frac{43.5-45.9}{\sqrt{\frac{5.33^2}{34} +\frac{6.21^2}{40} } }[/tex]".
Step-by-step explanation:
The given values are:
Bear island:
n1 = 34
[tex]\bar{x_1}[/tex] = 43.5
S₁ = 5.33
Goat island:
n2 = 40
[tex]\bar{x_2}[/tex] = 45.9
S₂ = 6.21
Now,
⇒ [tex]t=\frac{\bar{x_1}-\bar{x_2}}{\sqrt{\frac{S_1^2}{n_1} +\frac{S_2^2}{n_2} } }[/tex]
On substituting the given values, we get
⇒ [tex]t=\frac{43.5-45.9}{\sqrt{\frac{5.33^2}{34} +\frac{6.21^2}{40} } }[/tex]
The consumption of asparagus results in the release of methanethiol and S-methyl thioesters metabolites in the urine. To some people, these metabolites have a very distinctive odor, but others cannot detect the odor ("asparagus anosmia"). How common is asparagus anosmia?
In a genetic study aiming to find the genetic markers supporting the phenotype, researchers contacted 6909 participants in a large scientific cohort and found that 4161 had asparagus anosmia. Assuming that the cohort is representative of the American adult population, obtain a 90% confidence interval for the true population of Americans with asparagus anosmia. Use technology, for instance, the 1-PropZInt function in the TI graphing calculator or the Statistics / Proportion / 1-sample function (Confidence Interval tab) on CrunchIt!.
Answers
Answer:
The 90% confidence interval for the true population of Americans with asparagus anosmia is (0.5926, 0.6120).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
Researchers contacted 6909 participants in a large scientific cohort and found that 4161 had asparagus anosmia.
This means that [tex]n = 6909, \pi = \frac{4161}{6909} = 0.6023[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6023 - 1.645\sqrt{\frac{0.6023*0.3977}{6906}} = 0.5926[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6023 + 1.645\sqrt{\frac{0.6023*0.3977}{6906}} = 0.6120[/tex]
The 90% confidence interval for the true population of Americans with asparagus anosmia is (0.5926, 0.6120).

Answers
Answer:
a. Base area, B= 24 square units.
b. Volume, V = 96 cubic units.
Step-by-step explanation:
Given the following data;
Length of sides = 4 units
Width of sides = 6 units
Height = 4 units
a. To find the base area, B;
The base of a rectangular prism is a rectangle.
Area of rectangle, B = length * width
Area of rectangle, B = 4 * 6
Area of rectangle, B = 24 square units.
b. To find the volume;
Volume of rectangular prism = base area * height
Volume= 24 * 4
Volume = 96 cubic units.
