In a class of 34 students…
> 12 study German
> 25 study Spanish
> 6 do not study either language
One student in the class is selected at random.
Find the probability that this student studies both languages.
Answer:
My answer to this question would be :
6 = 34 - (12+25) + X
6 = -3 + X
9 = X
The probability would be : 9/34 = 0.26
I am not really sure i will check it later and tell you .
I would be happy if you let me know it was wrong or not , too .
Part of the population of 6,000 elk at a wildlife preserve is infected with a parasite. A random sample of 50 elk shows that 9 of them are infected. How many elk are likely to be infected?
Answer:
Based on the sample, the probability of an elk being infected is 2/50. Multiply this by the number of elk: 2/50(6000) = 240

What is the value of x?
Answer:
B
Step-by-step explanation:
Since UV is a tangent then ∠ WUV = 90°
WZ = WU = x - 1 ( both radii of the circle ) , then
WV = x - 1 + 2 = x + 1
Using Pythagoras' identity in the right triangle
WU² + UV² = WV² , that is
(x - 1)² + (2x - 4)² = (x + 1)² ← expand factors using FOIL
x² - 2x + 1 + 4x² - 16x + 16 = x² + 2x + 1
5x² - 18x + 17 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides
4x² - 20x + 16 = 0 ← divide through by 4
x² - 5x + 4 = 0
(x - 1)(x - 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 4 = 0 ⇒ x = 4
But x ≠ 1 as radius x - 1 = 0
Thus x = 4 → B

Which expression represents the algebraic phrase "eleven less than seven times a number"? 11x - 7 7 x minus 11 11 + 7x 11 minus 7 x
Answer:
7x minus 11
Step-by-step explanation:
7x would be 7 times whatever x is. then you subtract 11 from 7x. the reason you’re subracting 11 from 7x is because 11 has to be less than 7x (i understand negatives, but we’re not using that in this problem.)
Answer: (B) 7x minus 11
Step-by-step explanation: Just to make sure it was correct!

Angle D and Angle F are supplementary. The measure of Angle D is (3x + 5), and the measure of angle F is (2x). What is the measure of Angle D? (It’s not asking for x)
Step-by-step explanation:
Two angles are called suplementary when their measures add to 180 degrees.
D+F= 180
3x+5+2x= 180
5x+5=180
5x= 175
x= 35°
angle D = 3x+5= 3(35)+5= 110°

Answer:
A = 1863
Step-by-step explanation:
There are a few ways you could do this but I will do the one I know best.
Keep in mind the area is the L(enght x W(idth) = A(rea)
There are two long rectangles if you cut off the square in the middle so find the area of those two first.
31 x 23 = 713
713 x 2 = 1426 (Did this to get the area for both of them.
Now find the area of the square.
23 x 19 = 437
The you would add them all up together to get 1426 + 437 = 1863
Hope this helps :)
Answer:
1,863
Step-by-step explanation:
ok I will try to explain my answer as easy and under standable as posable.
ok what I did is the left and right side of the building I drew two lines down the middle to crate two huge rectangles on each side and one small rectangle in the middle ok. hope you understand! if you don't click the file down below.
ok after you see the file you will under stand a lot better.
ok
what I did is on the left and right triangle I did 31 tall and 23 wide. what you do I multiply the two numbers.
31 x 23 = 713
then the middle triangle is 23 wide and I did 31 - 12 to get the tall of the triangle since it did not give it to you so I got 19.
so I multiplied 23 by 19 and got 437.
so you adding all three triangles and I get 1,863 by
713 + 713 + 437 = 1,863
hope this helps
The value of W is inversely proportional to m. If w=8 then m=25, What is m when W is 20?Show me all the steps please?
Answer:
m = 10
Step-by-step explanation:
The values of w is inversely proportional to m
Mathematically the above statement is expressed as:
w ∝ 1/m
w = k × 1/m
w = k/m
Where k is the Proportionality Constant
First step
Solve for k
If w=8 then m=25
w = k/m
8 = k/25
Cross Multiply
k = 25 × 8
k = 200
Second step
what is m when w=20? Show me the steps please
We solve for m
w = k/m
k = 200
20 = 200/m
Cross Multiply
20m = 200
m = 200/20
m = 10

Verify the identity sin^2x = cos^2x sec^2x-cos^2x
Answer:
Step-by-step explanation:
The right side of the identity
[tex]cos^{2} x sec^{2} x - cos^{2} x\\= cos^{2} x (\frac{1}{cos^{2} x} ) - cos^{2} x\\= 1 - cos^{2} x\\= sin^{2} x[/tex]
which is the same as the left side of the identity

at 3 weeks old, a corn is 4 inches tall and at 15 weeks it is 44 inches tall. calculate the rate of change.
Answer:
Im not a hundred percent sure if this is the right answer but im pretty sure it is 3.33333 repeated so the rate of change is 3 inches per week.
Step-by-step explanation:
I calculated the problem by subtracting the weeks from each other subtracting the amount of length corn has grown too. I found that the corn grew 40 inches in 12 weeks. So I divided the amount of weeks and the amount it has grown and it gave me 3.333333 repeated which makes the answer 3 inches per week. correct me if im wrong...

Is this non linear or linear?
Answer:
Non-linear
Step-by-step explanation:
If we were to graph this table, the points will form a curve.
This is most likely a exponential function, not a linear function.
A linear function would form a straight line on a graph.
