The theoretical probability of selecting a rough bead is 1/2.
Total number of beads = 52
Number of rough beads = 26
Number of smooth beads =26
What is the probability?Probability is the measurement of possibilities.
P(event) = favorable outcomes/total outcomes
P(rough) = number of rough beads/ total beads
P(rough) =26/52
P(rough) =1/2
Therefore, the theoretical probability of selecting a rough bead is 1/2.

Shaneya purchased a membership to play basketball at her local gym. The membership costs $75 for the year, plus she pays $3 to rent equipment each time she goes. If Shaneya doesn't want to spend any more than $150 on basketball for the year, what is the maximum amount of times can she go to the gym to play?
Answer:
25
Step-by-step explanation:
Step one:
given data
We are told that Shaneya purchased a membership to play basketball at her local gym.
Costs = $75 for the year,
Rent = $3 for equipment each time she goes
Given that she has $150 to spend,
Step two:
Firstly, let us model the situation
let the total amount she has to spend be y
and the number of time she goes to the gym be x
y= 75+3x
for y= 150, let us find the value of x
150= 75+3x
150-75= 3x
75= 3x
divide both sides by 3
x= 75/3
x=25 times
The maximum amount of times is 25

Answer:
3) 5/2
Step-by-step explanation:
5x - 2y = 20
(First, put it in slope intercept form: y = mx + b).
5x - 2y - 5x = 20 - 5x --> Subtracted 5x on both sides of the equation
- 2y = -5x + 20 --> Simplified
-2y/-2 = (-5x + 20)/-2 --> Divided by -2 on both sides
y = 2.5x - 10 --> Simplified
Since formula is, y = mx + b, then:
m (slope): 2.5
b (y-intercept): -10
Therefore, the answer is 3) 5/2
Hope this helped! <3
Let's solve for y.
5x − 2y = 20
Step 1: Add -5x to both sides.
5x−2y+−5x=20+−5x
−2y=−5x+20
Step 2: Divide both sides by -2.
−2y/−2 = −5x + 20/−2
y = 5/2x − 10
Answer:
y = 5/2x − 10
Slope = x, therefore, the slope = 5/2.

Identify the GCF that was factored out of the polynomial -7t2 -42t -49
Answer:
-7
Step-by-step explanation:
You could take out a factor of -7.
-7t²/-7 = t²
-42t/-7 = 6t
-49/-7 = 7
So the GCF is -7.
