Answer:
B
Step-by-step explanation:
there is no angle e unless i am reading this incorrectly, but i double-checked all the other answer choices and they are all correct, so B is the answer:)
Answer:
see attached
Step-by-step explanation:
Solve the problem.
Two forces of 575 newtons and 271 newtons act at a point. The resultant force is 657 newtons. Find the angle between the forces.
The resultant force is
→F=321.9N at−165.4°
The equilibrant is
→Feq=321.9N at14.6°
Explanation:
This problem requires that we resolve the force vectors into x- and y-components.
Once this is done, we can add the components easily, as the one 2-dimensional problem will be two 1-dimensional problems.
Finally, we will convert the resultant force into standard form and find the equilibrant.
Resolve into components:
F1x=F1cos180°=215(−1)=−215N
F1y=F1sin180°=0N
F2x=F2cos(−140°)=126(−0.766)=−96.5N
F1y=F1sin(−140°)=126(−0.643)=−81.0N
Note the change of the angle used to give the direction of F2. Standard angles (rotation from the x-axis; counterclockwise is +) should be used to avoid sign errors in the results.
Now, we add the components:
Fx=F1x+F2x=−311.5N
Fy=F1y+F2y=−81.0N
Technically, this is the resultant force. However, it should be changed back into standard form. Here's how:

you roll three six sided dice. what is the probability that exactly two of the dice are odd?
Answer:
3C2 * (.5)^2 * (.5)^1
.375
Step-by-step explanation:
...
The probability that exactly two of the dice are odd is 3/8
What is probability?"It is finding out the possibilities of the occurrence of an event."
Formula to find the probability of an event:"P(A) = n(A) / n(S)
where, n(A) is the number of favorable outcomes of an event A
n(S) is the total number of outcomes for an experiment"
What is Binomial theorem of probability?[tex]P=~ ^nC_r\times p^r \times q^{n-r}[/tex]
where, p is the probability of success and q is the probability of failure
For given example,
We roll three six sided dice.
We need to find the probability that exactly two of the dice are odd
the probability of success i. e. dice is odd would be,
⇒ p = 3/6
⇒ p = 1/2
So, the probability of failure would be,
⇒ q = 1 - p
⇒ q = 1 - 1/2
⇒ q = 1/2
Also, n = 3 and r = 2
Using Binomial distribution the required probability would be,
[tex]\Rightarrow P=~ ^nC_r\times p^r \times q^{n-r}\\\\\Rightarrow P=~ ^3C_2\times (\frac{1}{2} )^2 \times (\frac{1}{2} )^{3-2}\\\\\Rightarrow P =\frac{3!}{3!(3-2)!}\times \frac{1}{4} \times \frac{1}{2}\\\\ \Rightarrow \bold{P=\frac{3}{8}}[/tex]
Therefore, the probability that exactly two of the dice are odd is 3/8

24 + f = 54
Show some work
Answer: 30
Step-by-step explanation:
24 + f = 54
f = 54 - 24
f = 30
Answer:
f=30
Step-by-step explanation:
You want to get x by itself on one side, so in order to do that, you need to subtract the 24, and if you do it one side, you need to do it to the other side.
That would give you:
24-24+f=54-24
then simplify it to be:
f=30

Answer: x = 13
Step-by-step explanation:
They are equal so set them equal and solve for x.
(4x+1) = 53
4x = 52
x = 13
Answer:
Since the lines l and m are parallel,
angle (4x + 1) and angle 53 are both corresponding angles
We know that corresponding angles are equal, so:
4x + 1 = 53
4x = 52
x = 13
Which is the best estimate of 90/7 divided by 1 3/4?
Answer:
7 17/49
Step-by-step explanation:
Convert mixed numbers to fractions:
= 90/7 ÷ 7/4
Apply the fraction rule:
= 90/7 * 4/7
Multiply fractions:
90 * 4 / 7 * 7
Simplify:
360/49
Convert improper fractions to mixed numbers:
= 7 17/49

Find slope can anyone give me a step by step
Answer:
slope is 6/1 (or 6)
Step-by-step explanation:
your y-intercept is 3, so that means the point will be (0,3).
from there, you can start plotting points. up 6, over 1 (to the right)
the equation for a line is y=mx+b, so whatever number is in m will always be your slope, and whatever number is in b will be your y intercept

Write the equation 4x + 2y - 6 = 0 in the slope-intercept form (y = mx + b).
Answer:
y= -2x+3
Step-by-step explanation:
First, you want to isolate the variable 2y on its own.
It would look like this: 2y= -4x+6
Then, divide every term by two.
It would look like this: y=-2x+3
Hope it helped.

For a continuous random variable X, P(23 ≤ X ≤ 66) = 0.25 and P(X > 66) = 0.14. Calculate the following probabilities. (Leave no cells blank - be certain to enter "0" wherever required. Round your answers to 2 decimal places.)
Complete question :
For a continuous random variable X, P(23 ≤ X ≤ 66) = 0.25 and P(X > 66) = 0.14. Calculate the following probabilities. (Leave no cells blank - be certain to enter "0" wherever required. Round your answers to 2 decimal places.)
a. P(X < 66)
b. P(X < 23)
c. P(X = 66)
Answer:
P(X < 66) = 0.86
P(X < 23) = 0.61
P(X = 66) = 0
Step-by-step explanation:
Given that:
X, P(23 ≤ X ≤ 66) = 0.25 and
P(X > 66) = 0.14 ;
Recall:
P(x ≤ a) + p(x ≥ a) = 1
Then ; P(X < 0.66) = 1 - 0.14 = 0.86
Hence,
P(X < 0.66) = 0.86
P(23 ≤ X ≤ 66) = 0.25
P(X < 66) = 0.86
Hence,
P(X < 23) = 0.86 - 0.25 = 0.61
Probability that a continuous random variable is exactly equal to a particular number equals 0
Hence,
P(X = 66) = 0

If 3x-y=12, then y/3=?
Answer:
4
Step-by-step explanation:
Answer:
-4
Step-by-step explanation:
To find what y equals, x has to be 0.
3x-y=12
3(0)-y=12
-y=12 (multiply by -1 so y is not negative)
y=-12
Because y=-12 you need to do -12/3 to get your answer to y/3
-12/3=-4
