Answer:
0.00390625
Step-by-step explanation:
For coins :
Number of rolls, trials, n = 4
P(heads) = 0.5
Using binomial probability formula :
P(x =x) : nCr * p^x q ;
P(obtaining exactly 4 heads) = 4C4 * 0.5^4 * 0.5^0 = 1 * 0. 0625 * 1 = 0.0625
P(even number from 4 coin tosses)
Even faces = (2,4,6)
Total faces = (1,2,3,4,5,6)
P(success) = 3/6 = 0.5
P(obtaining exactly 4 even) = 4C4 * 0.5^4 * 0.5^0 = 1 * 0. 0625 * 1 = 0.0625
Hence, obtaining 4 even outcomes and 4 heads = 0.0625 * 0.0625 =0.00390625

Yoko received a $70 gift card for a coffee store. She used it in buying some coffee that cost $8.62 per pound. After buying the coffee, she had $26.90 left on her
card. How many pounds of coffee did she buy?
Answer:
She bought 5 pounds of coffee.
Step-by-step explanation:
We are looking for how many pounds so pounds would be your x.
each pound costs $8.62.
You are taking the money she payed for the coffee away from the $70 she received.
Set up your equation
70 - 8.62x = 26.90
Solve for x
Subtract 70 from both sides 70-70 (Cancels out) - 8.62x= 26.90-70
-8.62x = -43.10
Divide -8.62 from each side. -8.62/-8.62(cancels out) x = -43.10/-8.62 (two negative numbers multiplied or divided by each other makes a positive)
x=5

find the mean median and mode. 53, 13, 34, 41, 26, 61, 34, 13, 69
Answer:
Mean = 43
Median = 75 ( since its even amount, you add the two middle numbers, if its an odd amount, just do the middle number)
mode = 13

Answer:
median
Step-by-step explanation:
Answer:
Range
Step-by-step explanation:
It is not a mean (average)
it is not givin us what the median is (middle #)
and it is not asking us the mode (most repeated #)
The "range" of a list a numbers is just the difference between the largest and smallest values.

Answer:
A, or 33,439.99
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 10/100
r = 0.1 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 15,600.00(1 + 0.1/1)(1)(8)
A = 15,600.00(1 + 0.1)(8)
A = $33,439.99

The graph of f(x) = 3 . 2*-3 is shown below. g(x) is a transformation of f(x).
How would you write the equation for the function g(x)?
Answer: (c)
Step-by-step explanation:
Given
Function [tex]f(x)[/tex] is [tex]3\times 2^x-3[/tex]
Also, [tex]g(x)[/tex] is the transformation of [tex]f(x)[/tex]
From the graph, it is clear that [tex]g(x)[/tex] passes through the point [tex](0,5)[/tex]
Now check the option which satisfies the condition
option (c) seems to obey it
[tex]g(x)=3\cdot 2^x+2\\g(0)=3\cdot 2^0+2\\g(0)=3\cdot 1+2\\g(0)=3+2\\g(0)=5[/tex]
Therefore, option (c) is correct.

The length of three sides of a triangle are 12, 35 and 37 centimeters. Determine whether the triangle is a right triangle. Show your calculations to support your answer.
Answer:
it is a right triangle
Step-by-step explanation:
confirm if it is a right triangle using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
12² + 35²
144 + 1225 = 1369
square toot of 1369 is 37
so
12² + 35² = 37²
Which describes the number and type of roots of the equation x^3 + 121x = 0?
a. 2 real roots, 1 imaginary root
b. 1 real root, 2 imaginary roots
c. 3 real roots
d. 3 imaginary roots
Answer:
b; 1 real root and 2 imaginary roots
Step-by-step explanation:
From here, we have
x(x^2 + 121) = 0
x = 0 (1 real root)
or
x^2 + 121 = 0
x^2 = -121
x = √(-121) (2 imaginary roots)
so is would be two complex numbers from above

On a hike, Oscar's elevation change after 12 minutes was-84 feet. Assuming his elevation was changing at a constant rate, what integer represents his elevation change per minute?
Answer: -7
Step-by-step explanation:
From the information given, we are.l told that Oscar's elevation change after 12 minutes was -84 feet.
Since his elevation was changing at a constant rate, his elevation change per minute will be:
= -84 feet / 12
= -7feet/minutes
Therefore, the integer is -7.
