Answer:
If there are 20 pens in total, and the probability of choosing a blue pen is 40%, then there are 0.4 times 20, or 8 blue pens in Amanda's bag.
Let me know if this helps!
The number of blue pens would Amanda expect to see in her bag is 8.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
In our daily time, there are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.
Total number of pens = 20
Probability of choosing blue pen = 40%
Since,
Probability = Desire item / sample space
So,
Probability of choosing blue pen = Number of blue pens / total number of pen
0.40 = Number of blue pens / 20
Number of blue pens = 0.40 × 20 = 8
Hence "the number of blue pens would Amanda expect to see in her bag is 8".

Andre ran 2 kilometers in 15 minutes and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. Did they run the same rate? Explain or show your reasoning.
You might use:
-ratio tables
-double number lines
-unit rates
-Equivalent ratios
yeah
Answer:
no, Andre ran at a sperm of 8km/hr while jada ran at 9km/hr you can find that by Andre going 2km in 15 minutes which turns to hours by multiplying by 4/4 to get 8/60 which 60 minutes is 1 hour then jada multiply by 3/3 which would be 9/60
Create an equation with one solution of x = −5.
9x − (x − 3) = 2x − (__ + x)
7.4 #7
Answer:
9x-(x-3) = 2x - (-5 + x)
Step-by-step explanation:
Let's say blank is the variable a.
9x-(x-3) = 2x - (a + x)
Simplify the equation:
9x-(x-3) = 2x - ( a + x)
9x - x + 3 = 2x - a - x
8x + 3 = x - a
7x + 3 = -a
a = -7x - 3
Plug in -5 for x:
a = -7*-5 - 3 = 35 - 3 = 32
a = 32 so the equation with one solution of x = -5 would
9x-(x-3) = 2x - (-5 + x)

H. line 6
I. line d
to 12 gives a sum
Answer:
F
Step-by-step explanation:
x-9=15 will equal to 24 so x=24
if Allison is 15 but she is 9 years younger then Pam, Pam is x, so all you have to do is count up from 15, so 15+9 which equals 24 Pam is 24 making F the right choice
Y is 1 1/3 times x.
Which ratio is equivalent to y : x ?
A. 3:3
B. 4:3
C: 7:3
D: 3:7
Answer:
B. 4:3
Step-by-step explanation:
Note: I use the '&' mark to symbolize mixed fractions, since it's easy to mistake the whole number for part of the numerator. Don't do this for assignments, as it's not proper.
1 & 1/3 = 4/3
Thus, the answer is B. 4:3.

There were 52 riders on a bus. The next bus had 25% more riders. How many riders were on the next bus?
Answer:
65 riders
Step-by-step explanation:
52 times 0.25 = 13 (25% of 52)
52 + 13 = 65
Answer:
There were 65 riders on the next bus.
Step-by-step explanation:
To solve this you have to know what 25% of 52 is, and since 25% of 52 is 13, you have to add 52 and 13 so you get 65 as your result.

please solve this class 10 function
if f={(x,y):3y-2x=6} find f-¹(x)
Answer:
f −1 (x)= x/2+3
Step-by-step explanation:
Here take y=f(x)
Then y=2x−6
⇒2x=y+6
⇒x= y/2 +3
Now switch x and y in the resulting equation. The resulting function of x is the inverse.
⇒y= x/2 +3
Thus the inverse function is f −1 (x)= x/2+3

Reset
Answer:
A. 0, - 9
Step-by-step explanation:
Given
x² + 9x = 0
x (x + 9 ) = 0
Either
x = 0
or,
x + 9 = 0
x = - 9
Hope it will help :)
The values of x that satisfy the equation x² + 9x = 0 are x = 0 and x = -9.
Option A is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
x² + 9x = 0
To solve for x, we can factor the expression:
x(x + 9) = 0
According to the zero product property, this equation is satisfied if either x = 0 or x + 9 = 0.
We have two solutions:
x = 0 or x = -9
Therefore,
The values of x that satisfy the equation x² + 9x = 0 are x = 0 and x = -9.

What is 3-6? Please help meeeee
your answer is going to be -3
Answer:
The Answer to 3-6 is -3!
Step-by-step explanation:
Think of it as a regular problem at first, 6-3: Switch the rolls!
6-3= 3 So when you switch the numbers back to 3-6, you get -3.
The answer has to have a negative sign (-) because it is a negative, a number below zero.
3-3= 0, 3 is half of 6, 6 is the number you need to subtract so you have to go below zero because subtraction is all about taking away from that first number. So 3-3= 0, 0-3= -3.
