The experimental probability of pulling a blue marble and then a yellow marble is 0.075 or 7.5%, which is closest to answer option B.
What is probability?Probability is a statistical term that describes the possibility that something will occur.
Since there is only one blue marble in the bag, the likelihood of getting a blue marble on the first draw is 1/6.
After the blue marble is replaced, the probability of drawing a yellow marble on the second draw is 2/6, since there are now 2 yellow marbles out of a total of 6 marbles in the bag.
The probability of sketching a blue marble and subsequently a yellow marble in the same attempt is:
P(blue then yellow) = P(blue) x P(yellow | blue)
P(blue then yellow) = (1/6) x (2/6)
P(blue then yellow) = 1/18
Since the marbles are replaced after each draw, the probability of drawing a blue marble and then a yellow marble is independent of one attempt to the next.
The experimental probability of pulling a blue marble and then a yellow marble in 40 attempts can be calculated by dividing the number of times it occurred by the total number of attempts:
Experimental probability = number of times blue then yellow was pulled / total number of attempts
Experimental probability = 3 / 40
Experimental probability = 0.075
Therefore, the experimental probability of pulling a blue marble and then a yellow marble is 0.075 or 7.5%.

What is
is 1/4 + 9/10y -3/5y +7/8 written in simplest form?
Answer:
Step-by-step explanation:
[tex]\frac{1}{4}+\frac{9}{10}y - \frac{3}{5}y+\frac{7}{8}\\\\=\frac{1}{4}+\frac{7}{8}+\frac{9}{10}y-\frac{3}{5}y\\\\[/tex]
Combine like terms. 1/4 and 7/8 are like terms and LCD of 4 and 8 is 8
9/10y and -3/5y are like terms and LCD of 10 , 5 is 10
[tex]= \frac{1*2}{4*2}+\frac{7}{8}+\frac{9}{10}y-\frac{3*2}{5*2}y\\\\=\frac{2}{8}+\frac{7}{8}+\frac{9}{10}y-\frac{6}{10}y\\\\=\frac{9}{8}+\frac{3}{10}y[/tex]

A traoezoid has basses of 36 1/2 noches and 13 1/2 noches and a height of 10 1/2 inches.What is the área of the trapezoid in square inches?
Answer:
Area of trapezoid = 262.5 inches²
Step-by-step explanation:
Given:
Larger Base = [tex]36\frac{1}{2}[/tex] inches = 36.5 inches
Smaller Base = [tex]13\frac{1}{2}[/tex] inches = 13.5 inches
Height of trapezoid = [tex]10\frac{1}{2}[/tex] inches = 10.5 inches
Find:
Area of trapezoid
Computation:
Area of trapezoid = [Sum of parallel line / 2]Height
Area of trapezoid = [(a+b) / 2]h
Area of trapezoid = [(36.5 + 13.5) / 2]10.5
Area of trapezoid = [(50) / 2]10.5
Area of trapezoid = [25]10.5
Area of trapezoid = 262.5 inches²

Gordon is trying to save up $2000 for a new saxophone he makes 12.50 per hour at his job at the coffee shop but he needs to set aside half of his hourly wage to pay his regular bills How many 40-hour weeks will he need to work before he can afford the saxophone?
A. 320 Weeks
B. 40 Weeks
C. 8 Weeks
D. 6.25 Weeks
Answer:
he will need to work 8 40-hour weeks.
Explanation:
since gordon has to set aside half of his wage to pay his bills, he can only save $12.50 ÷ 2 = $6.25 for the saxophone.
we can find how much money gordon saves from a 40-hour week by multiplying this by 40: $6.25 × 40 = $250.
now, divide the total amount of money he has to save by the amount he saves each week: $2000 ÷ $250 = 8.
he will need to work 8 40-hour weeks before he can afford the saxophone.

Find the equation of the graphed line.
On a coordinate plane, a line goes through (0, negative 6) and (6, 0).
a.
y = negative x minus 6
c.
y = x minus 6
b.
y = x + 6
d.
y = negative x + 6
Answer:
y = x -6
Step-by-step explanation:
First find the slope
m= ( y2-y1)/(x2-x1)
= (0- -6)/(6-0)
=( 0+6)/(6-0)
= 6/6
= 1
The slope is 1 and the y intercept is -6
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = x -6
Answer:
the answer is C
Step-by-step explanation:
y = x -6
