Two birds start from the same nest and head off in opposite directions. The speed of the first bird is 15mph more than the speed of the second.After 6 hours the two birds are 402 miles apart. Find the speed of each bird?
Answer:
41 mph26 mphStep-by-step explanation:
The rate at which distance is increasing between the birds is ...
r = d/t = (402 mi)/(6 h) = 67 mi/h
This is the sum of the speeds of the two birds, so is 15 mph more than double the speed of the slower bird. That bird's speed is then ...
(67 -15)/2 = 26 . . . miles per hour
The faster bird is 15 mph faster so is 26+15 = 41 mph.
The slower bird's speed is 26 mph; the faster bird's speed is 41 mph.
when the equation is graphed is it linear or nonlinear ??
Answer:
Nonlinear
Step-by-step explanation:
This is nonlinear because its parent function is y = [tex]x^{2}[/tex]. The parent function of a linear equation is y = x.

Answer:
.00002
Step-by-step explanation:
2 * 10 ^-5
Move the decimal 5 places to the left since the exponent is negative
2.
We will need to add zeros on the left Add 4 zeros since we can move it one place already
.00002
Answer:
(D) 0.00002
Step-by-step explanation:
Let's first forget about the 2 in the expression and focus on [tex]10^{-5}[/tex].
If we have 10 to a positive number, that many times the decimal place will move to the right. It's the opposite for 10 to the power of a negative number.
The decimal place will move 5 places to the LEFT.
So:
[tex]0000010\\\\0.00001[/tex]
Now we remember the two, and multiply this by two to get 0.00002.

Use a only once in your inequality.
Answer:
-1 + w ≤ 4

w is greater than -1 = -1 + w
Less than or equal to 4 = (anything less than or equal to 4)≤4
Answer:
[tex]-1<w\leq 4[/tex]
This shows that w is greater than -1 and less than or equal to 4

Determine whether each equation is an identity or whether it has no solution.-3(2x+1)=2(-3x-1) help is this a no solution or infinite
Answer:
No solution.
Step-by-step explanation:
Distribute.
-3(2x + 1) = 2(-3x - 1)
-6x - 3 = -6x - 2
Combine like terms.
-6x - 3 = -6x - 2 add 3 to both sides
-6x = -6x + 1 add 6x to both sides
0 = 1 this is false.
Because we ended up with a false equation, there is no solution to this equation.
Answer:
no solution
Step-by-step explanation:
Perform the indicated multiplication, using the distributive property.
-3(2x+1)=2(-3x-1) becomes -6x - 3 = -6x - 2
This has no solution because -3 is never equal to -2.

Find the area and perimeter of the shaded region.
Answer:
Area: [tex]50\pi -100[/tex]
Perimeter: 20[tex]\pi[/tex]
Step-by-step explanation:
If we take half of one of these "pedals" we can see that it is simply 1/4 of a circle with radius 5, subtracted by a triangle. Let's calculate this half-pedal.
[tex]1/4(25 \pi) - 1/2(5* 5)[/tex]
That means 4 pedals is equal to:
[tex]8(1/4(25\pi) - 1/2 (25))[/tex]
[tex]50\pi - 100[/tex]
So.. The area of the shaded region is [tex]50\pi -100[/tex]
Perimeter is even simpler. the half-pedal is just 1/4 of the circumference of the circle. The circumference is just [tex]10\pi[/tex], which means our half pedal is:
[tex]1/4(10\pi )[/tex]
Multiplying by 8, our perimeter is just 20[tex]\pi[/tex].

Kaitlin compared the statistics from her team's baseball season. She determined that having fewer hits did not imply that a player caught more or fewer balls. What should she conclude? a. There is no correlation between the number of hits and the number of balls caught. b. There is a correlation between the number of hits and the number of balls caught. There may or may not be causation. Further studies would have to be done to determine this. c.There is a correlation between number of hits and number of balls caught. However, there is no causation. This is because there is probably a decrease in the number of balls caught with a decrease in the number of hits.
Answer: c.There is a correlation between number of hits and number of balls caught. However, there is no causation. This is because there is probably a decrease in the number of balls caught with a decrease in the number of hits.
Step-by-step explanation:
Correlation is a term used to define a relationship between two variables.Causation is a term used to define the effect of one variable on other.Given, Kaitlin compared the statistics from her team's baseball season. She determined that having fewer hits did not imply that a player caught more or fewer balls.
There is a correlation between number of hits and number of balls caught. However, there is no causation as " fewer hits did not imply that a player caught more or fewer balls.".
This is because there is probably a decrease in the number of balls caught with a decrease in the number of hits.
Hence, the correct option is "c".
For the equation, determine whether the equation is true for all, some, or no values of x.
Explain how you know.
Answer:
You can check if an equation is true for all some or no values of x by simply to try and solve the equation if you get something like x = x, then the equation is true for all, if you get a specific answer like x=3, then it is true to some values, in simple terms. Try and solve the equation there is no other way to check unless you solve, I don't know if there is another way but this is just my intution.

The large rectangle below represents one whole. What percent is represented by the shaded area? (URGENT)
Answer:
40%
Step-by-step explanation:
The whole rectangle is split into 5 parts. Two out of 5 parts are shaded.
Set up a fraction:
[tex]\frac{\text{Shaded}}{\text{Whole}}=\frac{2}{5}[/tex]
Convert into a decimal:
[tex]\frac{2}{5}= 0.4[/tex]
Multiply the decimal by 100 to get the percent:
[tex]0.4*100=40[/tex]
So, forty percent of the rectangle is shaded.
Hope this helps.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
The percentage of the shaded rectangular boxes in the large rectangle is 40%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of rectangular boxes in the large rectangle = 5
Number of shaded rectangular boxes in the large rectangle = 2
The percentage of shaded rectangular boxes.
= 2/5 x 100
= 2 x 20
= 40%
Thus,
The percentage of the shaded rectangular boxes in the large rectangle is 40%.

The t distribution approaches the _______________ distribution as the sample size ___________.
Answer:
Normal; increases.
Step-by-step explanation:
In Statistics and probability, a student t-distribution also known as the t-distribution refers to the continuous probability distribution which can be used to estimate population parameters when the population variance or standard deviation is not known (unknown) and the sample population is relatively small. The student t-distribution is a statistical distribution which was published in 1908 by William Sealy Gosset.
The t-distribution approaches the normal distribution as the sample size increases because the parameters becomes negligibly smaller.
This ultimately implies that, when the degree of freedom of a t-distribution curve is increased in comparison with that of a normal distribution, the value of probability becomes significantly similar.
In the triangles, TR = GE and SR = FE.
Triangles S T R and F G E are shown. Angle S R T is 56 degrees. Angle F E G is 42 degrees. Sides T R and G E are congruent. Sides S R and F E are congruent.
if Line segment G F = 3.2 ft, which is a possible measure of Line segment T S?
Answer:
3.2 ft
Step-by-step explanation:
the only thing you need to know is that congruent means that all the side and the same and the shape can be flipped and still look the same so the measure of the line segment is 3.2ft

Answer:
Below in bold.
Step-by-step explanation:
-6x + 3y = -7
The x intercepts occur when y = 0, so
-6x + 3(o) = -7
x = -7/-6
x = 7/6
So the x-intercept = (7/6, 0).
The y intercept:
-6(0) + 3y = -7
y = -7/3.
So the y-intercept = (0, -7/3.t).

Name four fractions between 5/11 and 5/6
Answer:
6/11, 20/33, 2/3, 25/33 (answers vary)
Step-by-step explanation:
First, we need to convert both of these fractions to the same denominator. To do that, we need to find the least common denominator for both fractions.
6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72
11: 11, 22, 33, 44, 55, 66, 77
The LCM of 6 and 11 is 66. (6 * 11 = 66)
Now, we multiply 5/6 by 11/11 and 5/11 by 6/6.
[tex]\frac{5}{6} *\frac{11}{11}=\frac{55}{66}\\\\\\\frac{5}{11} *\frac{6}{6} =\frac{30}{66}[/tex]
Now, we can just choose four numbers between 30 and 55 and get our answer (remember to simplify!).
[tex]\frac{36}{66} =\frac{6}{11}[/tex]
[tex]\frac{40}{66}=\frac{20}{33}[/tex]
[tex]\frac{44}{66} =\frac{2}{3}[/tex]
[tex]\frac{50}{66} =\frac{25}{33}[/tex]
