Answer:
14/20
Explanation:
Sasha tried to get a marble 20 times. 14 of those times she got a yellow marble.
The experimental probability, which is the probability of choosing a yellow marble when Sasha actually tries choosing marbles from the bag.
The theoretical probability is based on the chance that Sasha will get a yellow marble, 7/70, is from the amount of marbles in the bag of yellow colour.

Answer:
1. -40=12x+8 : x=-4
2. -4x+2≥-6x : x≥−1
3. -11≤7x+3 : x≥−2
Step-by-step explanation:
1. Step 1: Flip the equation.
12x+8=−40
Step 2: Subtract 8 from both sides.
12x+8−8=−40−8
12x=−48
Step 3: Divide both sides by 12.
12x
12=−48
12
x=−4
3. Step 1: Flip the equation.
7x+3≥−11
Step 2: Subtract 3 from both sides.
7x+3−3≥−11−3
7x≥−14
Step 3: Divide both sides by 7.
7x
7
≥
−14

x≥−2
Answer:
We are given that The dependent variable is production; that is, it is assumed that different levels of production result from a different number of employees.
Number of Assemblers(x) One-Hour Production(y) (units)
2 11
4 18
1 7
5 29
3 20
a. Draw a scatter diagram.
Solution : Refer the attached figure
b. Based on the scatter diagram, does there appear to be any relationship between the number of assemblers and production? Explain.
Solution: The equation that shows the relationship between the number of assemblers and production is
Where y is One-Hour Production (units) and x is the Number of Assemblers
c.Compute the correlation coefficient.
Solution:
Formula of correlation coefficient:
x y xy
2 11 22 4 121
4 18 72 16 324
1 7 7 1 49
5 29 145 25 841
3 20 60 9 400
Sum: 15 85 306 55 1735
n=5
Substitute the values in the formula :
The correlation coefficient is 0.00351
