Answer:
13.6 units (to 3 significant figures)
Step-by-step explanation:
C ( -4,6) and D (-4,-5)
the formula for distance is : √(x2 - x1)² + (y2-y1)²
in this case x1= -4 , x2= -4 and y1 =6 , y2 = -5
so substitute the values and you will get the answers
A point on a wheel moves at 32π/9 radians per minute. How many seconds are required for the point to complete 7 revolutions?
Answer:
The number of seconds required to complete 7 revolutions is 236.28 s.
Step-by-step explanation:
Given;
speed of the point on the wheel, ω = 32π/9 rad/min
number of revolutions made by the point, θ = 7 rev
The time taken for the point to make 7 revolutions is calculated as follows;
1 rev = 2π rad
[tex]time (t) = \frac{\theta }{\omega} = \theta \ \times \frac{1}{\omega} \\\\t = (7 \ rev \ \times \frac{2 \pi \ rad}{1 \ rev} ) \ \times (\frac{1}{32 \pi/9 \ \frac{rad}{\min} } )\\\\t = (7 \times 2\pi \ \ rad) \times (\frac{9}{32 \pi }\frac{\min}{rad}) \\\\t = 14 \pi \ (rad) \ \times \ \frac{9}{32 \pi}\ (\frac{\min}{rad} )\\\\t = \frac{14 \times 9}{32} \ \min\\\\t = 3.938 \ \min\\\\t = 3.938 \ (\min) \times \frac{60 \ s}{1 \ \min} \\\\t = 236.28 \ s[/tex]
Therefor, the number of seconds required to complete 7 revolutions is 236.28 s.
If you need to round up to the nearest tenth for this question, you'd put 236.3

a grilled chicken salad at a popular fast food restaurant contain 650 mg of sodium.which is 27% of recommended daily amount.what is the total recommended daily amount of sodium?
Answer:
286.34 mg
Step-by-step explanation:
Let the recommended amount is x.
ATQ,
A grilled chicken salad at a popular fast food restaurant contains 650 mg of sodium which is 27% of recommended daily amount.
Mathematically,
[tex]27\%\ of\ x=650 \\\\\dfrac{27}{100}x=650\\\\x=\dfrac{650\times 100}{227}\\\\x=286.34\ mg[/tex]
So, the recommended amount of sodium is equal to 286.34 mg.
Does anyone have an answer or can help
Answer:
set them equal to each other and solve for x

Kenneth is painting his kitchen and bathroom. He bought 5 gallons of paint to paint the two rooms. He uses 1/4 of that amount to paint the bathroom and the rest to paint the kitchen.
Answer:
He used 1.25 gallons for the bathroom, and he used 3.75 gallons for the kitchen.
Step-by-step explanation:
1/4=25%=.25
Multiply 5 by .25
5*.25=1.25
Subtract 1.25 from 5
5-1.25=3.75
1.25 gallons for bathroom
3.75 gallons for kitchen

Answer:
around 13.18
Step-by-step explanation:
the middle square is 2*2 = 4
the triangle then is 2^2 + 6^2 = 40 -> sqrt40 = 6.325
and then 2^2 + 2^2 = 8 -> sqrt8 = 2.828
4+6.325+2.828 = 13.18
Answer:
8
Step-by-step explanation:
because since it is a square all sides are the same length you can either add 2+2+2+2 or you can do 2x2=4x2 which equals 8

Step-by-step explanation:
Eighteen individuals are scheduled to take a driving test at a particular DMV office on a certain day, eight of whom will be taking the test for the first time. Suppose that six of these individuals are randomly assigned to a particular examiner, and let X be the number among the six who are taking the test for the first time. a. What kind of a distribution does X have (name and values of all parameters)
Answer:
X has an hypergeometric distribution, with parameters:
Size of the population is N = 18.
Size of the sample is n = 6.
Number of successes n is k = 8.
Step-by-step explanation:
The people are chosen without replacement, which means that the hypergeometric distribution is used.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Eighteen individuals are scheduled to take a driving test at a particular DMV office on a certain day, eight of whom will be taking the test for the first time.
This means that [tex]N = 18, k = 8[/tex]
We consider a success being a person taking the test for the first time, because X is the number among the six who are taking the test for the first time.
Suppose that six of these individuals are randomly assigned to a particular examiner.
This means that [tex]n = 6[/tex]
a. What kind of a distribution does X have (name and values of all parameters)
X has an hypergeometric distribution, with parameters:
Size of the population is N = 18.
Size of the sample is n = 6.
Number of successes n is k = 8.
