Answer:
Logically, the answer is either 12 or 42
Select all instances in which the variable described is binomial.
a. A coin flip has two outcomes: heads or tails. The probability of each outcome is 0.50. The random variable represents the total number of flips required to get tails.
b. A quality check on a particular product must meet five guidelines. All products are made in the same factory under the same conditions. The random variable represents the total number of products out of 35 tested that pass inspection.
c. Based on the parents' genetics, each of 6 children from a particular pair of parents has a 0.30 probability of having blue eyes. The random variable represents the total number of children from this pair of parents with blue eyes.
d. There are two banking options for customers of ABC Bank, checking or savings. The random variable represents the total number out of 567 customers with a checking account.
e. The probability of drawing an ace in a standard deck of cards is 0.08. Seven cards are drawn without replacement. The random variable represents the total number of ace cards observed.
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

8th grade math
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

Can someone help me solve 44 m - 5 DM
Answer:
43.5 meters
Step-by-step explanation:
I hope this helps!!!!
Answer:
You have two different variables, M and DMHence we can factor out a variable m(44-5D)8m + 5 + 13m – 5 = 42. What is the value of M?
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

The measure of the exterior angle of the triangle is
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°.

Answer: It is number A
Step-by-step explanation: n Euclidean geometry, an isosceles trapezoid is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid. Alternatively, it can be defined as a trapezoid in which both legs and both base angles are of the same measure.
Area: ½ x (sum of the lengths of the parallel sides) × height of the trapezoid
Perimeter: the sum of the top and bottom sides+2(leg of the trapezoid)
Number of vertices: 4
Number of edges: 4
Properties: Convex polygon, Cyclic
Type: Trapezoid, Quadrilateral
Line of symmetry: 1

If x+4 is a factor of a polynomial p(x) , what is the remainder when p(x) is divided by x+4
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)
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)

Patti ran the race in 7.1 minutes. Maisha ran it in 7.01 minutes.
What is the value of the 1 in Maisha's time? ?
What is the value of the 1 in Patti's time?
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.

What's 10/7 divided by 3/7
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.

What is the slope intercept form.
Answer:
y = -[tex]\frac{3}{7} x - 2[/tex]
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]
