Answer is given below
Step-by-step explanation:
given data
average length of all 1015 fishes = 98.06 mm
randomly selects 50 fishes average length = 101.04 mm
solution
- When we get here, we mean to measure, so here we measure a fish in a square lake.
- And the variable means that a fish varies from fish to fish, so the length of the fish in the squares
- parameter mean that all individuals in the population so the parameter is average length of all 1015 fish in square lake
- statics is selct of individual in sample so statistic is average length of random sected so fish in square lake
We can answer the question above by using the trigonometric functions and the concept of similar triangles.
Given that cos (L) is 4/5. The length of sides PN and NL can be solved. Please see solution below.
4/5 = NL / 15 ; NL = 12
Solving for PN,
PN² + 12² = 15²
The value of PN is 9.
Then, using the concept of similar triangles,
KN/(KN + NL) = PN/ KM
Substituting the known values,
4/(4 + 12) = 9 / KM
The value of KM is 36.
Answer:
43 degrees for the first problem
Step-by-step explanation:
On the first problem we see, we are given that one angle is 231 degrees. After counting the sides of this shape, we see it is a 4-sided quadrilateral. This means that the total amount of degrees in this shape equals 360 degrees. Since each unknown degree is represented by the same value (w), we can deduce that all of these unknown angles are equal to each other.
Let's set up our problem now.
360 degrees = the amount of degrees in a quadrilateral
231 degrees = the given amount of degrees we have so far
In order to see how many degrees we have left in the quadrilateral, let's subtract the number degree we already know from the total degree number that we know: 360 - 231 = 129
Now we see that the remaining three angles have a total of 129 degrees. This doesn't mean we're done.
3 congruent angles together = 129 degrees
We need to find the degree of a single unknown angle now. This can be done by simply dividing the mass total of the three congruent angles by the amount of congruent unknown angles there are.
129/3 = 43
Our final answer is 43 degrees.
