Experimental probability of correctly answering both questions by guessing = 1/4 .
Tail (T) = True
Head (H) = False
Number of possible outcome = 2
Head (H) or Tail (T).
Probability = number of occurrence/number of possible outcome.
Since we can only have one T or F in a toss.
number of occurrence = 1
Probability of answering first question correctly = 1/2
Probability of answering second question correctly = 1/2
Probability of answering both questions correctly = Probability of answering first question correctly * Probability of answering second question correctly
Probability of answering both questions correctly = 1/2 x 1/2
Probability of answering both questions correctly = 1/4

Jamie is twice as old as Natalie now. Give years ago the sum of their ages was 26. How old is each person now?
answer:
8. 67 and 17. 36
step-by-step explanation:
hi there!
to find out the age of both girls, i believe that we should divide the number 26 by 3 because jamie is twice as old as natalie meaning ( natalie ) is younger
26/3
= 8. 67
meaning 8.67 is how old natalie is/was
add 8.68 to itself once and you will get jamie's age!
8. 67 + 8. 67
= 17. 34
meaning 17. 34 is how old jamie is/was
sorry if i misread the question or made it a little confusing! but i do hope that this ends up helping you! :)

Step-by-step explanation:
A line has a slope of 0 and passes through the point (-4, 3). What is its equation in slope-intercept form.
Answer:
y = 3
Step-by-step explanation:
We already know the slope, all we need to do is find the y-intercept.
You have to plug the coordinates into the equation, y = 0x + b
y = 0x + b
3 = 0(-4) +b
3 = 0 + b
3 = b
The equation is y = 3

A house that costs $125,400 appreciates at a rate of 3% each year. What is the value of the
home after 3 years.
a.$137027.97
b.$275503.80
c.$114449.19
d.$3385800
Answer:
The value after three years is $137,027.97
Step-by-step explanation:
Here, we want to get the value of the home after 3 years
Generally, we have the exponential formula as follows;
y = P(1 + r)^t
where P is the original cost which is $124,400
r is the rate of increase which is 3% = 3/100 = 0.03
t is the time which is 3 years
Substituting these values;
y = 125400(1 + 0.03)^3 = $137,027.97
