We want to get the probability of selecting an orange, putting it back, then selecting a block that is not orange.
We will see that the probability is P = 0.1799
In the bag we have:
6 yellow blocks4 orange blocks2 green blocks5 blue blocks.For a total of 6 + 4 + 2 + 5 = 17 blocks.
First we want to find the probability of getting an orange block, as all the blocks have the same probability of being randomly drawn, the probability of randomly drawing an orange block is equal to the quotient between the number of orange blocks and the total number of blocks.
We get:
p = 4/17
Now we put the orange block back and we want to take a block that is not orange, the probability is computed in the same way:
q = (6 + 2 + 5)/17 = 13/17
The joint probability (this is, the probability of these two events happening together) is just the product of the individual probabilities.
We get:
P = p*q = (4/17)*(13/17) = 52/289 = 0.1799

Which of the following represents a function?
(-1, 2), (-2, 1), (-1, -2), (-2, -1)
(3, 4), (-3, 2), (3, 8), (5, 5)
(2, 3), (4, 3), (-2, -3), (-4, -3)
(5, 1), (5, 2), (5, 3), (5, 4)
Step-by-step explanation:
If in any set, you can find 2 or more points that lie on the same vertical,
then it is NOT a function, that is, the same value of x yields 2 or more different
values of y, you don't have a function.
e.g. D is definitely not a function. You have (-2,4) and (-2,-4) , the same x of -2 giving you a y value of 4 and -4.
Ben and Mack stopped at a restaurant to eat. Ben purchased 2 hot dogs and 2 drinks for $4.75. Mack purchased 3 hot dogs and 1 drink for
$7.75. Which system of equations can be used to determine the price of each hot dog, x, and each drink, y?
A. 2x + 2y = 4.75
3x + y = 7.75
OB. 2x + 2y = 7.75
3x + y = 4.75
OC. X + 2y = 7.75
2x + 3y = 4.75
D. x + 2y = 4.75
2x + 3y = 7.75
Answer:
A is the answer
Step-by-step explanation:
Let x equal hotdogs and y equal drinks
2 hotdogs plus 2 drinks = 4.75
3 hotdogs plus 1 drink = 7.75

An object is launched at 9.8 meters per second (m/s) from a 308.7-meter tall platform. The function that represents the object's height s at time t seconds after launch is
s(t) = −4.9t2 + 9.8t + 308.7,
where s is in meters. When does the object strike the ground?
this is the full answer for you're Q
please give me good
The time taken by the object to hit the ground will be 9 seconds.
What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that an object is launched at 9.8 meters per second (m/s) from a 308.7-meter tall platform. The function that represents the object's height s at time t seconds after launch is
s(t) = −4.9t²+ 9.8t + 308.7
To find the time taken put the function equal to zero.
−4.9t²+ 9.8t + 308.7 = 0
t² - 2t - 63 = 0
t² - 9t + 7t - 63 = 0
t ( t - 9 ) +7 ( t - 9 ) = 0
( t - 9 ) ( t + 7 ) = 0
t = 9 and -7(ignore)
t = 9 seconds
Therefore, the time taken by the object to hit the ground will be 9 seconds.

Answer:
6 11/15
Step-by-step explanation:
So the equation is 6 9/10 - 1/6, you gotta have similar denominators to have an easy subtraction process. So 9/10 - 1/6. Both numbers go into 60. 10×6 so that becomes the new denominator. Now your numerator, the 9 is times 6 because the 10 gets times by 6 so 9 times 6 = 54. You got your first fraction done and you put I back with the whole number so 6 54/60. So 1/6 10 times 6 equals 60 so now 1/60 times the 1 by 10 whatever you do to the bottom you do to the top 1 times 10 is 10 so we got out second fraction 10/60 so now it's 6 54/60 - 10/60, 54 - 10 = 44 so your answer is 6 44/60 but we can simplify so 44 ÷ 2 = 22 and you do it to the bottom 60 ÷ 2 = 30 now we got 22/30 we can divide by 2 again and we get 11/15. Put it back with the whole number and we get 6 11/15

A. y + 2x = 12
y = x + 3
B. y = -2x + 10
y = 2
C. x + y = 3
y = -3 (2x - 1)
D. y = 2/3x
y = 5/3x - 3
Answer: A
Because y =x + 3 shows there’s a point at (0,3) and y + 2x = 12 solves to y = -2x + 12 meaning there’s a point at (0,12) and the graph shows that

Answer:
D(t) = 2,280 - 60t
for D(15) compare the eqns and substitute the value of t.
D(15) = 2,280 - 60(15)
D(15) = 1,380 miles.
In the context of the qn, the Chang family travels 1,380 miles in 15 hours.
On Saturday morning, Ahmed decided to take a bike ride from one end of the 15-mile bike trail to the other end of the bike trail and back. His average speed the first half of the ride was 2 mph faster than his speed on the second half. Find an expression for Ahmed's total travel time. If his average speed for the first half of the ride was 12 mph, how long was Ahmed's bike ride?
The expression which relates the total time taken and the time taken for the trip is [15s + 15(s+2)] / s² + 2s and 2.32 hours respectively.
Travel time = distance ÷ speed
Second half of the trip :
Speed = s mph Distance covered = 15 milesTime taken for second half of trip :
Time taken = 15 / s
First half of the trip :
Speed = s + 2 mphTime taken for first half of trip :
Time taken = 15 / (s+2)
Total time taken :
First half + second half
15/(s+2) + 15/s = [15s + 15(s+2)] / s² + 2s
B)
If s = 12
Substitute s = 12 into the expression :
[15(12) + 15(12+2)] / 12² + 2(12)
[180 + 210] / 144 + 24
390 / 168
= 2.32 hours
Therefore, the total time taken is 2.32 hours.

What is -(x + 4) - 3x = x in Distributive property?
Answer:
x = -4/5
Step-by-step explanation:
Original equation: -(x+4)-3x=x
Remember distributive property allows us to get rid of the parenthesis by bringing a multiplication from outside to inside a parenthesis.
-(x+4) = -x-4
= -x-4-3x=x
Now we combine like terms in this case we have (-x) and (-3x)
= -4x-4=x
Subtract x from both sides
= -4x-4=x
-x -x
----------------
-5x-4=0
Add 4 to both sides
-5x-4=0
+4 +4
---------------
-5x=4
Our final step is to divide both sides by -5
-5x=4
---- ----
-5 -5
x = -4/5

Answer:
b = 12.5 ft
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here A = 25 and h = 4 , then
[tex]\frac{1}{2}[/tex] × 4 × b = 25 , that is
2b = 25 ( divide both sides by 2 )
b = 12.5 ft
