Answer:
The correct answer is 24.
Step-by-step explanation:
Jose wants to have an average mean of 25 points per game in his 6 basket ball matches.
Total points Jose plans to achieve in 6 games is 25 × 6 = 150.
Points score by him in the first five matches are 28, 24, 26, 27 and 21.
Total points in 5 matches is 126.
Thus the points he need to score in his next game to have an average mean of 25 is given by 150 - 126 = 24.
What is the difference between the measure of an arc and the arc length? Explain.
The measure of an arc is the degree/radian measure. You measure the central angle to find the measure of an arc.
The arc length is the actual length (like 2pi inches or 7 cm, etc.). You find the length of the curved part (the arc), not the straight distance between the 2 points given.

The combined volume of all the things and aquarium is 1.25×10 to the six power gallons the aquarium plants to install a new dolphin take with a volume of 250,000 gallons what was the total volume of all the tanks at the aquarium after the new dolphin tank is installed
Answer:
1,500,000 gallons
Step-by-step explanation:
In this question, we are to calculate the total volume of the aquarium after installing a new dolphin tank.
Mathematically, to calculate this, we simply need to add the the volume of the new dolphin tank to the volume of the things in the aquarium before bringing the dolphin tank.
The volume of all the things in the aquarium before installing the dolphin tank is 1.25 * 10^6 = 1,250,000 gallons
now let’s add the volume of the dolphin tank which is 250,000 gallons
that would be 1,250,000 + 250,000 = 1,500,000 gallons or 1.5 * 10^6 gallons

find perimeter and area pleasee
Answer:
Perimeter: 36 m
Area: 60 m squared
Step-by-step explanation:
The perimeter is the sum of the exterior side lengths of the shape. Here, we see that there are two side lengths given, but we need to find the third one.
Notice that the triangle is split up into two right triangles, which means that we can use the Pythagorean Theorem to solve for half of the remaining side. The right triangles have hypotenuses of 13 and one leg of 12. That means the second leg will be [tex]\sqrt{13^2-12^2} =\sqrt{169-144} =\sqrt{25} =5[/tex].
So, the third side is made up of the two legs with length 5. This makes the length of the remaining side: 5 + 5 = 10.
Now, we can calculate the perimeter: P = 10 + 13 + 13 = 36 meters.
The area is calculated by the formula: [tex]A=\frac{1}{2} bh[/tex] , where b is the base and h is the height. Here, the base is what we found above, 10, and the height is the length that makes a perpendicular with the base, which is 12. So, the area is: [tex]A=(1/2)*10*12=(1/2)*120=60[/tex]. So, the area is 60 square meters.
Hope this helps!

A certain triangle has a 30° angle in a 60° angle. Which must be a true statement about the triangle
Answer:
It is a right triangle.
Step-by-step explanation:
A right triangle is a triangle with at least one angle with 90 degrees.
We know that every triangle has 180 degrees. The other unknown angle is 180 - (30+60) = 180 - 90 = 90. That means that the other angle is 90 degrees. Therefore, it is a right triangle
We also know that in this triangle, that the square of one side plus the square of another is side is equal to the square of the hypotenuse of the triangle. (According to Pythagorean theorem)

) Jennifer and Krystal have to stuff and mail 1000 envelopes for a new marketing campaign. Jennifer can do the job alone in 6 hours. If Krystal helps, they can get the job done in 4 hours. How long would it take Krystal to do the job by herself?
Answer:
12 hours
Step-by-step explanation:
Let's call the Jennifer's speed J, and the Krystal's speed K.
If Jennifer works alone, she can do the job in 6 hours, so:
J*6 = 1000
J = 1000/6 = 500/3
If Jennifer and Krystal work together, they can do the job in 4 hours, so:
(J+K)*4 = 1000
J+K = 250
Using the value of J, we can find K:
500/3 + K = 250
K = 250 - 500/3 = 250/3
Now, to find the time that Krystal would take if she works alone:
K * time = 1000
250/3 * time = 1000
time = 1000/ (250/3) = 1000*3/250 = 12 hours

Suppose oil spills from a ruptured tanker and spreads in a circular pattern. If the radius of the oil spill increases at a constant rate of 1.5 m/s, how fast is the area of the spill increasing when the radius is 30 m?
Answer:
The area of the oil spill is increasing at a rate 180 π m²/s, when the radius is 30 m.
Step-by-step explanation:
Derivative Rule:
[tex]\frac{d}{dx}x^n=nx^{n-1}[/tex] [tex]\frac{d}{dx}(y^n)=ny^{n-1}\frac{dy}{dx}[/tex]Given that
The radius of the oil spill increases at a rate 1.5 m/s.
i.e [tex]\frac{dr}{dt}= 1.5\ m/s[/tex]
We need to find the rate of area increase i.e [tex]\frac{dA}{dt}[/tex] .
We know,
The area of the oil spills A = [tex]\pi r^2[/tex] ( since it spreads in circular pattern)
[tex]\therefore A=\pi r^2[/tex]
Differentiating with respect to t
[tex]\frac{dA}{dt}=\pi. 2r\frac{dr}{dt}[/tex]
Plug the value of [tex]\frac{dr}{dt} =1.5 \ m/s[/tex]
[tex]\frac{dA}{dt}=\pi. 2r(3\ m/s)[/tex]
[tex]\Rightarrow \frac{dA}{dt}=6\pi r \ m/s[/tex]
Plug r= 30 m
[tex]\Rightarrow \frac{dA}{dt}=6\pi (30\ m) \ m/s[/tex]
=180 π m²/s
The area of the oil spill is increasing at a rate 180 π m²/s, when the radius is 30 m.

You bike 1 mile the first day of your training, 1.5 miles the second day, 2.5 miles the third day, and 4.5 miles the fourth day. If you continue this pattern, how many miles do you bike the seventh day?
Answer:
32.5 miles on the 7th day
Step-by-step explanation:
1, 1.5, 2.5, 4.5
We need to determine the pattern
We are adding .5 + 1/4(2^n)
Lets check
n=1 .5+ 1/4(2) = .5+ .5 =1
n =2 .5 + 1/4*2^2 = .5 +1 = 1.5
n=3 .5 + 1/4 ( 2^3) = .5 + 8/4 = 2.5
n=4 .5 + 1/4 (2^4) = .5 + 16/4 = 4.5
n = 5 .5 + 1/4 (2^5) = .5 +32/4 = 8.5
n = 6 .5 + 1/4 (2^6) = .5 + 64/4 =16.5
n=7 .5 + 1/4(2^7)= .5 + 1/4(128) = 32.5
They bike 32.5 miles
National League Hockey play-off games go into overtime if the score is tied at the end of a game. Overtime lasts until one of the teams scores a goal. From years of experience we know that the distribution of the lengths of the overtime periods is right skewed with a mean of 9.8 minutes and a standard deviation of 12 minutes. What is the (approximate) probability that a random sample of 30 overtime periods would have a (sample) mean length of more than 13 minutes? Give your answer to 3 decimal places, e.g, 0.123.
Answer:
0.07215 = 0.072 to 3 d.p.
Step-by-step explanation:
Central limit theorem explains that the sampling distribution obtained from this distribution will be approximately a normal distribution with
Mean = population mean
μₓ = μ = 9.8 minutes
Standard deviation of the distribution of sample means = σₓ = (σ/√n)
σ = 12 minutes
n = sample size = 30
σₓ = (12/√30) = 2.191
Probability that a random sample of 30 overtime periods would have a (sample) mean length of more than 13 minutes
Required probability = P(x > 13)
Since we've established that this distribution of sample means approximates a normal distribution
We first standardize 13 minutes.
The standardized score for any value is the value minus the mean then divided by the standard deviation.
z = (x - μ)/σ = (13 - 9.8)/2.191 = 1.46
Required probability
P(x > 13) = P(z > 1.46)
We'll use data from the normal probability table for these probabilities
P(x > 13) = P(z > 1.46) = 1 - P(z ≤ 1.46)
= 1 - 0.92785 = 0.07215

What is the range of possible sizes for side x? it is a triangle with one side having 4.0, and the other having 5.6. picture attached below, thanks in advance :)
Given:
Given that the two sides of the triangle are x, 4.0 and 5.6
We need to determine the range of possible sizes for the side x.
Range of x:
The range of x can be determined using the triangle inequality theorem.
The triangle inequality theorem states that, "if any side of a triangle must be shorter than the other two sides added together".
Thus, applying the theorem, we have;
[tex]x=4.0+5.6[/tex]
[tex]x=9.6[/tex]
Also, the the triangle inequality theorem states that, "the third side must be also larger than the difference between the other two sides".
Thus, we have;
[tex]x=5.6-4.0[/tex]
[tex]x=1.6[/tex]
Thus, the range of possible values for x are [tex]1.6<x<9.6[/tex]
In accordance with the triangle inequality theorem, the range for the length of the third side (x) in a triangle with sides of 4.0 and 5.6 is greater than 1.6 but less than 9.6.
Explanation:In the field of Mathematics, specifically geometry, to find the range of possible lengths of a side of a triangle, you need to understand the triangle inequality theorem. The triangle inequality theorem states that the length of a side of a triangle must be less than the sum of the lengths of the other two sides, but more than the absolute difference.
Given you have two sides, 4.0 and 5.6, the possible length for side x should be less than (4.0 + 5.6 = 9.6) and greater than the absolute difference (5.6 - 4.0 = 1.6). So, the range for side x should be 1.6 < x < 9.6.

Leah is measuring the weight of adult rhinos at the zoo. Which unit of measurement should she use to eliminate the need to write the values in scientific notation
Answer:
TONS!!!!!!!!!!!!Step-by-step explanation:
The tons should be used to measure the weight of the rhino to eliminate the scientific notation option fourth is correct.
It is given that Leah is measuring the weight of adult rhinos at the zoo.
It is required to find the unit of measurement she should use to eliminate the need to write the values in scientific notation.
Given options:
1) grams
2) feet
3) gallons
4) tons
What is measurement?It is defined as the numerical quantity that gives an idea about an object's weight, length, width, and many more. It can be used to compare two objects.
We know the feet are the unit of measuring the length and gallons are the unit of measuring the volume.
The grams and tons are the units of measuring the weight.
Grams would use to measure a small amount of weight whereas we would use the tons to measure a large amount of weight. Ton is a metric unit that equals 1000 kilograms.
Thus, the tons should be used to measure the weight of the rhino to eliminate the scientific notation option fourth is correct.

Total amount of rain each county received for five days. Palm Beach 2.3., Broward 3.5,and Dade 3.0. On average,how many inches of rain did each county received each day.
Answer: On average, each country receives 2.93 inches of rain each day.
Step-by-step explanation:
Since we have given that
Palm Beach = 2.3
Broward = 3.5
Dade = 3.0
So,the average inches of rain each country would receive each day would be :
[tex]\dfrac{2.3+3.5+3.0}{3}=\dfrac{8.8}{3}=2.93\ inches[/tex]

The newly elected Chancellor of the Galactic Federation is interested in the opinions of all citizens regarding economic conditions in the galaxy. Unfortunately, she does not have the resources to visit every populated planet or to send delegates to them. Describe how the Chancellor might organize a multi-stage sample to carry out her survey.
The Chancellor can use a multi-stage sampling method to gather citizen opinions by dividing the galaxy into various regions, selecting a sample of these regions, and then selecting a sample of planets within these regions for surveying citizens.
Explanation:The Chancellor could use a multi-stage sampling method to effectively gather data from the galaxy's population. This method involves breaking down the larger population into smaller, manageable subsets in a sequence of levels or 'stages'. Here's an example of how it could work:
First Stage: The Chancellor divides the galaxy into distinct regions (e.g., solar systems, clusters of stars, etc.). This is sometimes called 'clustering'.Second Stage: A random sample of these regions is selected for further study.Third Stage: Within the selected regions, a random sample of planets is chosen.Final Stage: Within the chosen planets, a random sample of citizens is surveyed.This method will make the task feasible and manageable, given the constraint of resources. It also ensures that a diverse range of opinions can be captured from all over the galaxy.

The number of hours of daylight y for day x (x = 1 to 365) in Anchorage, Alaska, can be modeled by y=7.0sin(2π365x−1.4)+12.4. What is the minimum number of hours of daylight in Anchorage?
Answer:
5.4 hours
Step-by-step explanation:
As the number of hours of daylight y is modeled as a function of sin, and sin has the minimum value of -1. Therefore
[tex]sin(2\pi 365x-1.4) \geq -1[/tex]
[tex]7sin(2\pi 365x-1.4) \geq -7[/tex]
[tex]7.0sin(2\pi 365x-1.4)+12.4 \geq 5.4[/tex]
[tex]y \geq 5.4[/tex]
So the minimum number of hours of daylight in Anchorage is 5.4 hours
Final answer:
The minimum number of hours of daylight in Anchorage, Alaska, can be found using the equation provided. By considering the minimum value of the sine function, we determine that Anchorage experiences a minimum of 5.4 hours of daylight.
Explanation:
The minimum number of hours of daylight in Anchorage, Alaska, can be determined by examining the mathematical model y=7.0sin(2ω⁄365x−1.4)+12.4.
The amplitude of the sine function in this equation is 7.0, which determines the maximum variation above or below the average value.
Since the sine function oscillates between -1 and 1, the minimum value of the sine part of the equation will be -1.
Therefore, the minimum number of hours of daylight, y, occurs when the sine function is at its minimum value. By substituting -1 into the equation, we get y=7.0×(-1)+12.4, which simplifies to y=5.4.
This means that the minimum number of hours of daylight in Anchorage is 5.4 hours.
