order these numbers from least to the greatest, 47/10,4.606,4+13/20,4.64
Answer:
From lowest to highest, the numbers would follow the following order:
1) 4.606, 2) 4.64, 3) 4 + 13/20, 4) 47/10.
Step-by-step explanation:
Given that the numbers 47/10, 4.606, 4 + 13/20 and 4.64 are presented, to order these from lowest to highest, the following calculations must be performed:
47/10 = 4.70
4,606
4 + 13/20 = 4 + 0.65 = 4.65
4.64
Therefore, from lowest to highest, the numbers would follow the following order:
1) 4.606, 2) 4.64, 3) 4 + 13/20, 4) 47/10.

be left after 8 days?
0.049 grams
Approximately 0 grams
1.375 grams
95.965 grams
Sodium has two radioactive cosmogenic isotopes (22Na, half-life = 2.605 years; 24Na, half-life = ~ 15 hours) that have been used as tracers in hydrologic studies.
Sodium-24 how much would be left after 8 days?Sodium-24, a radioactive isotope having a half life of 15 hours is used medically in blood studies and it decays by beta decay.
Na has received considerable attention in hydrologic research because it is a mobile element that participates in precipitation and dissolution reactions in ground water (clay formation, albitization of plagioclase). Their short half-lives (i.e. high decay rate) make their measurement relatively easy by common radioanalytical techniques.
Substantial concentrations of 22Na and 24Na have been measured in precipitation (Roedel, 1970; Perkins et al., 1970). However, no studies have as yet been published documenting the cosmogenic sodium systematics in ground or surface waters.

Assume that body masses of Goldfinch birds follow a normal distribution with standard deviation equal to 0.04 oz. An ornithologist would like to make some inference about the average body mass of Goldfinch birds. In particular, she would like to create a formula to compute 70 % confidence interval formula for the average body mass of this specie. Her equipment allows her to sample 10 birds, using the 10 independent measurements CREATE the formula to generate 70% confidence intervals. Explain the crucial steps.
Answer:
The formula to generate 70% confidence interval is: [tex][\overline{x} - 0.013, \overline{x} + 0.013][/tex], in which [tex]\overline{x}[/tex] is the sample mean.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.7}{2} = 0.15[/tex]
Now, we have to find z in the Z-table as such z has a p-value of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.15 = 0.85[/tex], so Z = 1.037.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
Assume that body masses of Goldfinch birds follow a normal distribution with standard deviation equal to 0.04 oz.
This means that [tex]\sigma = 0.04[/tex].
Sample of 10 birds:
This means that [tex]n = 10[/tex].
The margin of error is of:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]M = 1.037\frac{0.04}{\sqrt{10}}[/tex]
[tex]M = 0.013[/tex]
The lower end of the interval is the sample mean of [tex]\overline{x}[/tex] subtracted by M.
The upper end of the interval is the sample mean of [tex]\overline{x}[/tex] added to M.
Then, the formula to generate 70% confidence interval is: [tex][\overline{x} - 0.013, \overline{x} + 0.013][/tex], in which [tex]\overline{x}[/tex] is the sample mean.
Coupon A: $16 rebate on a $55 jacket
Coupon B: 35% off a $55 jacket
Coupon A gives the lower price ?
The price of coupon A is ? less than the price with Coupon B
Coupon B gives the lower price?
The price of coupon B is ? less than the price with Coupon A
Yes. Coupon B gives the lower price.
The price of coupon B is less than the price with Coupon A
How to determine which price is lower?Discount is defined as a deduction from the usual cost of something
Since there is a $16 rebate on a $55 jacket using Coupon A. The price when Coupon A is used will be:
price using Coupon A = $55 - $16 = $39
Since Coupon B gives a 35% discount on the price of the jacket. The price when Coupon B is used will be:
price using Coupon B = $55 - (0.35×55) = $35.75
Thus, the price of coupon B is less than the price with Coupon A

Therefore ,option 3 is hence the appropriate choices. By the Side-Angle-Side Triangle Congruence Theorem, these triangles are congruent.
Triangle definitionAny three points in a plane can be connected to create triangles, which have three sides and three angles. They were one of the very first geometric shapes to be studied. They are particularly important because any polygon, whether it has four, five, six, or n sides, may be split into a triangle.
Here,
From the provided figure, it is clear that there are two triangles.
ABC and EFG are the triangles.
AB = EF
AC = FG
BC = EG
As a result, the triangles ABC and EFG are congruent according to the triangle's SSS theorem, and angle A is equal to angle D.
Therefore ,D and E are hence the appropriate choices. By the Side-Angle-Side Triangle Congruence Theorem, these triangles are congruent.

The width of the footpath is 8.5 feet.
What is radius in a circle?Radius of a circle is the distance from the center of the circle to any point on it's circumference.
given equation is :x² + y² = (r)²
We have for the pool:
x² + y² = 2500 or x² + y² = (50)²
So, for the outside edge of the footpath
x² + y² = 3422.25 or x² + y² = (58.5)²
So, we find the radius of each circumference
For the outside edge of the poolr₁ = 50 feet
For the outside edge of the footpathr₂ = 58,5 feet
Then the width of the footpath is58,5 - 50 = 8,5 feet
Thus, width of the footpath is 8.5 feet.

Which term below refers to events that all have the same probability of occurring?
(1) same chance occurrences
(2) equal probability events
(3) evenly divided happenings
(4) equally likely outcomes
The term below that refers to events that all have the same probability of occurring is; (2) equal probability events
What is the probability of occurrence?By definition, we can say that the probability of occurrence of an event is defined as the number of trials in which a particular event happened divided by the total number of trials.
Probability = number of trials in which event happened/total number of trials.
Now, when we say that all items have the same probability of occurring, what we simply mean is they all have equal chance of occurrence or they all have equal outcomes. For example when we flip a coin, we have equal chance of getting a head or tail.
Thus, the term that best defines the above would be Option 2.

The volume of this sphere is 4500m³.
Find the length of the radius, r.
Answer:
[tex]r=\frac{15\sqrt[3]{\pi ^2} }{\pi }[/tex] meters
[tex]r=10.24[/tex] meters
Step-by-step explanation:
Here is the equation for the volume of a sphere
[tex]V=\frac{4}{3} \pi r^{3}[/tex]
Lets solve for [tex]r[/tex].
Multiply both sides of the equation by [tex]\frac{1}{\frac{4}{3}\pi}[/tex].
[tex]\frac{1}{\frac{4}{3}\pi}(\frac{4}{3}*(\pi r^3))=\frac{1}{\frac{4}{3}\pi}V[/tex]
Simplify the left side.
Combine [tex]\frac{4}{3}[/tex] and [tex]\pi[/tex].
[tex]\frac{1}{\frac{4\pi }{3}}(\frac{4}{3}*(\pi r^3))=\frac{1}{\frac{4}{3}\pi}V[/tex]
Multiply the numerator by the reciprocal of the denominator.
[tex]\frac{3}{4\pi } (\frac{4}{3}*(\pi r^3))=\frac{1}{\frac{4}{3}\pi}V[/tex]
Cancel the common factor of [tex]\pi[/tex] by factoring it out of the first term.
[tex]\frac{3}{4} (\frac{4}{3}*r^3)=\frac{1}{\frac{4}{3}\pi}V[/tex]
Combine [tex]\frac{4}{3}[/tex] and [tex]r^3[/tex].
[tex]\frac{3}{4}*\frac{4r^3}{3}=\frac{1}{\frac{4}{3}\pi}V[/tex]
Multiply the numerators on the left side of the equation. Then multiply the denominators.
[tex]\frac{12r^3}{4*3}=\frac{1}{\frac{4}{3}\pi}V[/tex]
[tex]\frac{12r^3}{12}=\frac{1}{\frac{4}{3}\pi}V[/tex]
Cancel the common factor of 12.
[tex]r^3=\frac{1}{\frac{4}{3}\pi}V[/tex]
Simplify the right side.
Combine [tex]\frac{4}{3}[/tex] and [tex]\pi[/tex].
[tex]r^3=\frac{1}{\frac{4\pi }{3}}V[/tex]
Multiply the numerator by the reciprocal of the denominator.
[tex]r^3=\frac{3V}{4\pi }[/tex]
Take the cube root of both sides of the equation to eliminate the exponent on the left side.
[tex]r=\sqrt[3]{\frac{3V}{4\pi } }[/tex]
Now we have an equation to find the radius.
Substituting our number for volume gives us
[tex]r=\sqrt[3]{\frac{3*4500}{4\pi } }[/tex]
Enter this into a calculator
[tex]\sqrt[3]{\frac{3*4500}{4\pi } }[/tex]
You can leave the answer in simplest radical form or as a decimal.
[tex]r=\frac{15\sqrt[3]{\pi ^2} }{\pi }[/tex]

Answer:

Step-by-step explanation:
Let the measure of /_M be 'x'. As reported,
/_N is 5 times of x = 5x
/_O is 4 times of x = 4x
In any ∆, sum of interior angles is 180°.
=> /_M + /_O + /_N = 180
=> x + 4x + 5x = 180
=> 10x = 180
=> x = 180/10 = 18
Angles are x = 18°
4x = 4(18°) = 72°
5x = 5(18°) = 90°
