Answer:

37.5% of the ice cream cups are vanilla

62.5% of the ic cream cups are chocolate

Step-by-step explanation:

15 + 25 = 40

15/40 = .375

0.375x 100 = 37.5

Then do the same for the chocolate to get that percentage.

Answer:

60%

Step-by-step explanation:

Write this as a fraction first or just simply divide it out

15/25 = 0.6

OR

15/25 = 3/5 = 0.6

Multiply this by 100 to change it to a percentage

0.6*100 = 60%

Tomtit [17]

Answer:

Step-by-step explanation:

We can use normal aproximation, assuming that the random variables are a lot of that means the sample size is large.

P(x>105) = P(z>\frac{105-100}{1})=P(z>5)

Using the normal distribution table,

P(z>5) = 0.00005

Hence, we can conclude that the probability that the stock’s price will exceed 105 after 10 days is very small.

Hope this helps!

How to convert y = - 2\5 x to standard form
coldgirl [10]
Bring it to the form ax + by = c, where a is positive, and there are no fractions in the equation.
Here, we need to add 2/5x to both sides:
2/5x + y = 0
Then multiply everything by 5 to get rid of the fraction
2x + 5y = 0 <==
