Answer:
The circumference of a circle is C = 2πr^2 (2nd power) Radius (r) is the distance from the center of the circle to the outside of it. To find radius divide the diameter (d) by 2. The diameter (d) of a circle is the radius (r) multiplied by 2. To find the diameter (d) you need to do C ÷ π.
For example):
Finding diameter - 76/3.14 = 24.19 (d)
Finding radius - 24.19/2 = 12.095 (r)
meera is researching cruising speeds of different planes. which airplane has a greater cruising speed
Answer:
50,350
is answer
Answer:
Step-by-step explanation:
Speed = rate = slope
Find slopes:
Table:
(10, 70)
(20, 140)
Speed = 7 km/min
Graph:
(6, 90) , (4, 60)
Speed = (90 - 60) / (6 - 4) = 30/2 = 15 km/min. the greater cruising speed

Suppose that five graduating seniors on a college basketball team receive the following first-
year contract offers to play in the National Basketball Association (zero indicates that the
player did not receive a contract offer): 0 0 0 0 $10000000
The college claimed that the average senior on this basketball team received a $2 million contract offer.
Explain how the college came up with this number and why this statement may be misleading.
9514 1404 393
Answer:
the average of the distribution is 2 millionthe distribution is highly skewedStep-by-step explanation:
The "average offer" is the average of the 5 offers: 4 that are 0 and 1 that is 10 million.
__
That will be misleading because the average is not very representative of the actual distribution. The actual distribution of offers is highly skewed toward lower values.

Three tickets to a movie costs $37.50. If all tickets were the same price, what would be the cost of 2 tickets?
Answer:
$25 I believe
Step-by-step explanation:
You would take $37.50 divided by 3 and get $12.50 which is the price of 1 ticket
Then you would multiply $12.50 x 2 to get $25
Answer: $25.00
Step-by-step explanation: First you would divide $37.50 by 3 and get the price of one ticket which would be 12.50. Then you would multiply 12.50 by two and get $25.00.

‐2(‐5i-4)+i+1 = 119
Answer:
i = 10
Step-by-step explanation:
-2(-5i-4)+i + 1=119
Distribute -2 into whats in the parentheses
10i+8+ i+1=119
Now combine like terms
(10i + i)+ (8+1)= 119
11i + 9 = 119
Subtract 9 from both sides
11i + 9-9= 119-9
11i = 110
Now divide by 11
11i/11 = 110/11
i= 10

slope: -2, y-intercept: -3
Write an equation of a line in slope intercept form with the given slip and y intercept
Answer:
Step-by-step explanation:
The slope intercept form of a line is Y=MX + B where M is the slope and B is the y-intercept.
We know both of these so the equation turns into Y=1/2X-3
Find the critical value Zc necessary to form a confidence interval at the level of confidence c=0.82 what does Zc=
Answer:
The z-critical values are:
[tex]z_{0.09}=-1.34\\\\z_{0.91}=1.34[/tex]
Step-by-step explanation:
The confidence level is, c% = 82%.
The significance level for the two tails are:
Left tailed:
[tex]\frac{\alpha}{2} =\frac{1-c\%}{2}[/tex]
[tex]=\frac{1-0.82}{2}\\\\=\frac{0.18}{2}\\\\\=0.09[/tex]
Right tailed:
[tex]1-\frac{\alpha}{2} =1-\frac{1-c\%}{2}[/tex]
[tex]=1-0.09\\\\=0.91[/tex]
The z-critical values are:
[tex]z_{0.09}=-1.34\\\\z_{0.91}=1.34[/tex]

What is the difference between 234 and 250
Hey there!
If you ever come across the word “difference” in mathematics (or math) it usual means “SUBTRACT” (or SUBTRACTION) so basically you’re going to SUBTRACT 234 from 250
Equation:
234 - 250 = -16

Instructions: Given the following image of two parallel lines cut by a transversal, find the value of x.
Answer:
Step-by-step explanation:
these lines are congruent, so they equal the same thing
9x + 1 = 10x - 5
subrtact 9x from 10x and add 5 to 1
6 = 1x
which is 6 = x
so x would be 6
since your thing doesnt want spaces the setups for them would be:
congruent
9x+1=10x-5
6
