Formula for speed is given by;
As per the given statement:
Susie ran a race. She ran 55 miles an hour, and the race took her t hours to complete.

Time = t hour
Substitute the given values in the given formula we have;
Multiply t both sides we get;
miles.
Therefore, 5t miles long was the race.
The modified recipe will make 14 servings.
Step-by-step explanation:
Given,
Eggs used = 3
Servings made = 6
Ratio of eggs to servings = 3:6
Eggs used in modified recipes = 7
Let,
x be the number of servings = x
Ratio of eggs to servings = 7:x
Using proportion;
Eggs to servings :: Eggs to servings
3:6::7:x
Product of mean = Product of extreme
Dividing both sides by 3
The modified recipe will make 14 servings.

Answer:
Step-by-step explanation:
If we call x the number of correct questions obtained in the 9 attempts, then:
x is a discrete random variable that can be modeled by a binomial probability distribution p, with n = 9 trials.
So, the p of x successes has the following formula.
Where:
n = 9
p = 0.6
We are looking for P(x<4)
By definition:
Then:
