Suppose you flip a fair coin
1000 times. What do you think
is the probability of getting
exactly 500 heads?
Answer:
50
Step-by-step explanation:
first estimate probably 50% depends also in luck
Answer:
about 0.02
Step-by-step explanation:
If you toss a coin 1,000 times the average (mean) number of heads equals 500, yet the probability that you will get exactly 500 heads in 1,000 tosses is about 0.02.

A roller coaster reaches a speed of 112.7 kilometers per hour. What is the estimated speed in miles per hour?
Answer:
70 miles per hour just finished doing the math :)
Step-by-step explanation:
f f(x) is a linear function, which statement must be true? f(x) has no constant term. f(x) has no x2-term. f(x) has no terms with a coefficient other than 1. f(x) has no x-term. Mark this and return
Answer:
f(x) has not x^2 term.
Step-by-step explanation:
Linear function is in the form of y=mx+b
In the linear function y=mx+b there is a constant term b
There is also an x term.
m is the slope of f(x). The value of 'm' can be any number.
If we have x^2 term in f(x) then it is quadratic function.
Linear function must always have x with exponent 1
True option is f(x) has not x^2 term.
A bacteria culture grows with constant relative growth rate. The bacteria count was 1296 after 2 hours and 531441 after 6 hours. Answer the following questions. 1. What is the relative growth rate
Answer:
1)k=1.50408
2)=64
3)P(t)=64e^(1.50408t)
4)=118098
5)t=6.42 hrs
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW
A bacteria culture grows with constant relative growth rate. The bacteria count was 1296 after 2 hours and 531441 after 6 hours. Answer the following questions.
1. What is the relative growth rate?
2. What was the initial size of the culture?
3. Find an expression for the number of bacteria after t hours.
4. Find the number of cells after 5 hours.
5. When will the population reach 1000000?
To find relative growth rate, expression below can be used
P(t)= Po*e^(kt)
Where k= growth rate
Po= initial amount
t= time in hours
We were given The bacteria count as 1296 after 2 hours and 531441 after 6 hours. This can be expressed below as
P(2)= P(o)e^(2k)= 1296.........eqn(1)
P(6)= P(o)e^(6k)= 531441........eqn(2)
If we find the ratio of the two eqn we have
531441/1296 =[P(o)e^(6k)]/[P(o)e^(2k)]
410.0625= e^(4k)
If we take Ln of both side
ln 410.0625=ln(e^4k)
k=1.50408
1)= k=1.50408
2)
From P(2)= Po*e^(2k)= 1296
1296=Po × e^(2×1.50408)
1296= Po × e^(3.00816)
Po=1296/e^(3.00816)
=64
3) the expression is P(t)=64e^(1.50408t)
4). P(5)=64e^(1.50408×5)
=118098
5) P(t)= 1,000,000
1000000=64e^(1.50408t)
1000000/64 = 64e^(1.50408t)
Ln(15625)=ln[e^(1.50408t)]
9.657=e^(1.50408t)
t=6.42 hrs
−3(2.5−k)+0.5(7+8k).
Answer:
7k-4
Step-by-step explanation:
(-3)(2.5)+(-3)(-k)+(0.5)(7)+(0.5)(8k)
-7.5+3k+3.5+4k
Then you combine like terms
-7.5k+3k+3.5+4k
(3k+4k)+(-7.5+3.5)
7k+-4

The sum of the measures of two acute angles is always greater than 90 degrees
Answer:
One acute angle will always measure between 0° and 90° . Two acute angles can sum to be either greater than, less than, or equal to a right angle. Two acute angles can be complementary angles (adding to 90° ). Two acute angles alone cannot sum to make a straight angle (180° )
