Answer:

50 marbles

Step-by-step explanation: The difference between the ratio of the red and green marbles is 4 units and the number value is 20 so its safe to say that 4 units is equal to 20 and thus one unit is 5 and because of the fact that there is a total of 10 units of marbles in the box according to the ratio, just multiply 5 and 10 which you get 50.

4 units = 20

1 unit = 20÷4 = 5

Total = 10 units

10 unit = 5 ×10 = 50

Ans : 50 marbles

What is the gcf of 35, 20,15
fgiga [73]

Answer:

Prime factorisation of the numbers -

\\  \sf \: 35 = 7 \times  \underline5 \\  \\  \sf \: 20 =  \underline5 \times 4 \\  \\  \sf \: 15 = 3 \times  \underline5 \\

As, we can see that the 5 is common in the both three numbers. So,

<u>GCF</u><u>,</u><u> </u> greatest common factor (35, 20, 15) = <u>5</u>

For a large supermarket chain in a particular​ state, a​ women's group claimed that female employees were passed over for manage
Natasha2012 [34]

Answer:

Step-by-step explanation:

Hello!

Tha claim is those female employees have less probability of being selected for management training than the males employees of a supermarket chain.

The company denies this claim and assures that the employees are picked at random from an eligible pool, i.e. that there is no gender bias in the manager selection

If you consider the variables:

X₁: Number of female employees selected for management training

X₂: Number of male employees selected for management training

The parameter of interest would be

p₁: population proportion of female employees selected for management training

p₂: population proportion of male employees selected for management training

If the company claims that there is no gender bias in the management selection is true, then the proportion of female employees selected for management training and the proportion of male employees selected for management training should be the same, symbolically: p₁ = p₂

If the company's claim is incorrect, then these proportions should be different: p₁ ≠ p₂

I hope this helps!
