Answer:
There are 60 marbles in the bag
Step-by-step explanation:
The total number of marbles times the probability of red marbles = number of red marbles
total * 7/10 = 42
Multiply each side by 10/7
total * 7/10 * 10/7 = 42*10/7
total
60
There are 60 marbles in the bag
Your real answer would be 49.75510204
Each of these questions is substantially the same as the others. The answer is, "it depends" on what you want a random sample of. If you want random people in the country, you will not get that from these protocols.
If you want random people that meet certain criteria (have phones, shop in eyeglasses stores, use specific venues), then these protocols will deliver.
The value of y in the given logarithmic equation is 3. The correct option is C. 3
<h3>Evaluating Logarithmic equation </h3>
From the question, we are to determine the value of y in the given logarithmic equation
The given equation is

By applying one of the laws of logarithm, we get

Now, express 64 in index form,

Since the bases are equal, we can equal the powers to get
3 = y
∴ y = 3
Hence, the value of y in the given logarithmic equation is 3. The correct option is C. 3
