Answer:
D
Step-by-step explanation:
I cannot assure you this, because it is extremely hard for me too. It is my best guess.
Plz mark as brainliest!!!
Answer:
6) 6
9) 40
10) 
11) 13
Step-by-step explanation:
6)A right triangle rule: if 2 legs are equal, the hypotenuse is the length of that leg*
9) Pythagorean Theorem

We know the hypotenuse (41) so we substitute that for c and 9 for b now we need to find a
which gives us 40
10) same with #6 but we do the opposite. SInce we have the hypotenuse, we can divide that by
because we know that if 2 legs are equal, the hypotenuse is multiplied by
. Multiply the numerator and denominator by
because we can't have a square root in the denominator.
11) like #9 we have the a and b but we need to find c
a=5 b=12 c=r
so
which gives us 13
Answer:
One solution
Step-by-step explanation:
If they intersect at ONE point, that ONE point is the solution for the whole system of linear equations
Answer:
ρ = 35% or 0.35
ρ with ^ =
or equivalently 46%
Step-by-step explanation:
ρ represents the population proportion of the bus riders, with a monthly pass, who are students.
The population proportion is simply the percentage of the entire population with a particular characteristic. We have been informed that in a city, 35% of the bus riders with a monthly pass are students. This means that 35% of the whole population of bus riders with a monthly pass are students. Therefore, our ρ is simply 35% or 0.35.
ρ with ^ represents the sample proportion of the bus riders, with a monthly pass, who are students. This is a statistic or an estimator as it is normally used to estimate the value of ρ, the population proportion. It is calculated using the formula;
ρ with ^ = 
where n represents the size of the sample and x the number of individuals in the sample with a certain desired characteristic. We have been informed that;
in a random sample of 50 bus riders with monthly passes, 23 are students.
Using the above formula and the values given we have;
ρ with ^ =
or equivalently 46%
Answer:
cos (A+B+C)
Step-by-step explanation:
as A,B,C, are triangle we have A,B and C as 180
