Answer:
The best prediction possible for the number of times both coins will land on heads is 16.
Step-by-step explanation:
For each time the two coins are flipped, there are only two possible outcomes. Either they both land on heads, or they not. Coin flips are independent, which means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
On a trial, probability of two heads.
Each trial has two coins, each with 0.5 probability of landing on heads. So the probability of two heads on a trial is:
[tex]p = (0.5)^2 = 0.25[/tex]
64 times
This means that [tex]n = 64[/tex]
What is the best prediction possible for the number of times both coins will land on heads?
The expected value. So
[tex]E(X) = np = 64*0.25 = 16[/tex]
The best prediction possible for the number of times both coins will land on heads is 16.
Find the sum of the measures of the exterior angles of a convex 39-gon
The sum of the measures of the exterior angles of a convex 39-gon will be 360°.
What is a polygon?The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.
The measure of the exterior angle of the 39-gon will be given as,
Exterior angle = 360° / 39
Then the sum of the measures of the exterior angles of a convex 39-gon will be given as,
⇒ 39 x (360° / 39)
⇒ 360°
The sum of the measures of the exterior angles of a convex 39-gon will be 360°.

if (x/3+1,y-2/3)is equal to (5/3,1/2) find the value of x and y
Answer:
The value of x is 2.
The value of y is [tex]\frac{7}{6}[/tex]
Step-by-step explanation:
x:
We have that:
[tex]\frac{x}{3} + 1 = \frac{5}{3}[/tex]
Multiplying everything by 3
[tex]x + 3 = 5[/tex]
[tex]x = 2[/tex]
The value of x is 2.
y:
We have that:
[tex]y - \frac{2}{3} = \frac{1}{2}[/tex]
Least common multiple between 3 and 2 is 6, which means that we multiply everything by 6.
[tex]6y - 4 = 3[/tex]
[tex]6y = 7[/tex]
[tex]y = \frac{7}{6}[/tex]
The value of y is [tex]\frac{7}{6}[/tex]

A 4-story building is 29 feet tall. Between which two whole numbers does the height of each story lie?
Answer:
7 & 8
Step-by-step explanation:
29÷4=7.25
7<7•25<8
The inequality of the height of the building is given by 7 < A < 8 , where A is the height of the building = 7.25 feet
Given data ,
A 4-story building is 29 feet tall
So , the height of the each story is given by the equation ,
To determine the height of each story in a 4-story building, we divide the total height of the building (29 feet) by the number of stories (4).
A = 29/4
On simplifying the equation , we get
29 feet ÷ 4 stories = 7.25 feet per story
Now , the inequality representing the height of the building between the whole numbers is given by
7.25 lies between 7 and 8
So , the inequality is 7 < A < 8
Hence , the height of each story in the 4-story building lies between 7 feet and 8 feet

The equivalent expressions are (a) and (c) and the proof is as follows
(a)
[tex](8x^6) * (xy^2)^3[/tex]
Open brackets
[tex](8x^6) * (xy^2)^3 = 8x^6 * x^{1*3}y^{2*3}[/tex]

Simplify: 14ba2+21ab2−ab2.
The given expression 14ba²+21ab²−ab² can be simplified to 14ba²+20ab².
What is simplification?In arithmetic, the operation and interpretation of a function to make it simpler or easier to grasp is known as simplifying, and the process itself is known as simplification.
The expression is given in the question, as follows:
14ba²+21ab²−ab²
When you add or subtract similar terms, you can combine their coefficients. In this case, 21ab² and -ab² have the same base (ab²) and so their coefficients can be added together. 21 - 1 = 20, so 21ab² - ab² = 20ab².
Thus, the given expression can be simplified to 14ba²+20ab².
