Answers
Answer:
A & C
Step-by-step explanation:
Option A: The variable described is binomial because we have a value of n for the experiment and a probability of success 0.5 due to the fact that we have only two possible outcomes, which satisfy the condition of chances of success and failure.
Option B: The variable described is not binomial because the outcome does not fall under the criteria of chances of success or failure of due to the fact that it's possible we have more than two criteria to classify the product.
Option C: The variable described is binomial because we have a definite value of n = 6 with a probability of success = 0.3. Thus, probability of failure will be 0.7 and so it fulfills the condition of success and failure.
Option D: The variable described is not binomial because we don't know if the 2 options are independent of each other.
Option E: Variable describes is not binomial because the cards are drawn without replacement. Also, each time that king is selected, the probability of another king being selected is not the same and for thus the variable is not a a binomial

8m + 5 + 13m – 5 = 42. What is the value of M?
Answers
Answer:
m = 2
Step-by-step explanation:
8m + 5 + 13m - 5 = 42
The 5s cancel each other out
8m + 13m = 42
21m = 42
Divide both sides by 21
m = 42/21
m = 2
What's 10/7 divided by 3/7
Answers
Answer:
3 1/3
Step-by-step explanation:
Answer: 3-1/3.
1. Convert the second fraction into a reciprocal. 3/7 turns in 7/3.
2. Multiply the fractions; multiply the denominator with the denominator and the numerator with the numerator. 3/7 x 7/3 = 70/21.
3. Simplify the result; divide both the numerator and denominator by 7 (their common multiple). 70/7 = 10, and 21/7 = 3. So, now you have 10/3.
4. Convert the reciprocal fraction. 10/3 = 3-1/3.

Step-by-step explanation:
slope-intercept form : y = mx + b
Solve for y.
Subtract 3x on both sides. You get --> 7y = -3x - 14
Divide by 7 on both sides. You get --> y = [tex]\frac{-3x-14}{7}[/tex]
Simplfy it. -14/7 = 2 so you get y = -[tex]\frac{3}{7} x - 2[/tex]

Cot (15 degrees)
Part I: Find two common angles that differ by 15 degrees. Rewrite this problem as the cotangent of a difference of those two angles.
Part II: Evaluate the expression (Please show steps)
Answers
Answer:
Part I: cot(15 degrees) = cot(45 - 30)
Part II: Evaluation is below
Step-by-step explanation:
Everything is done in degrees
Two angles that differ by 15 degrees that is easy to evaluate is 30 degrees and 45 degrees. The cot(15 degrees) = cot(45 - 30) = 1/tan(45-30) = (1+tan45tan30)/(tan30 - tan45) = (1+ sqrt(3))/(sqrt(3) - 1)
We rationalize this by multiplying 1+ sqrt(3) in the top and bottom, getting:
(4 + 2sqrt(3))/2 = 2 + sqrt(3)

Answer:
x = -2
Step-by-step explanation:
2+3x = −4(5+2x)
2+3x = (−4)(5)+(−4)(2x)(Distribute)
2+3x = −20+−8x
3x+2 = −8x−20
3x+2+8x = −8x−20+8x
11x+2 = −20
11x+2−2 = −20−2
11x = −22
11x/11 = −22/11
therefore, x = −2
Answer:
X= -2
Step-by-step explanation:
So first distribute on the right side
2+3x=-20-8x
Now add 8x on both sides
2+11x=-20
Now subtract 2 on both sides
11x= -22
Now divde 11 on both sides
-22/11
x=-2

The measure of the exterior angle of the triangle is
Answers
The question is incomplete below you will find the missing part.
The measure of the exterior angle of the triangle is
The missing picture is shown below.
The measure of exterior angle of the triangle is 92°.
As we know, the measure of the exterior angle of triangle is the sum of the two interior opposite angles of the triangle. In other words, we can say that the sum of two interior angles in the triangle is equal to the exterior angle which is supplementary to the third interior angle of the triangle.
So here the exterior angle of the triangle is given by (2x-2)°
the measure of its two interior opposite angles of the triangle will be x° and 45°.
So using the above concept
the measure of exterior angle = sum of the two interior opposite angles
⇒ 2x-2= x+45°
⇒2x-x = 45°+2°
⇒x =47°
the measure of exterior angle will be = 2x-2= (2*47°)-2 =92°
Therefore the measure of exterior angle of the triangle is 92°.

What is the value of the 1 in Patti's time?
Answers
Answer:
The value of 1 in Maishas time is hundredth
The value of the 1 in Pattis time tenth
Step-by-step explanation:
The place value of decimals begins at tenth and extends towards the right. Hence, the one decimal place in Pattis time has the value of tenth while the 1 in Maishas time occurring at the second decimal place has a place value of hundredth.
Hence the place value of decimals may be tenth, hundredth, thousandth etc depending on the number of decimal places and the digit of interest.
