If the 35 teaspoons of blue paint are there. Then for the purple paint, we need to add 42 teaspoons of red paint.
<h3>What are ratio and proportion?</h3>
A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A percentage is a mathematical expression in which two things are equal.
A mixture of purple paint contains 6 teaspoons of red paint and 5 teaspoons of blue paint.
To make the same shade of purple paint using 35 teaspoons of blue paint, then the amount of the red paint that you need will be
Let x be the amount of the red color needed.
Then we have

Let's find the remaining distance they must travel.
Total distance-distance covered
150-60=90 mi
Now, we need to find the average speed they need to travel per hour to reach the destination in 2.5 (2 1/2) hours.
90 mi/2.5 h=36 mi/h
They must travel at an average speed of 36mph to reach their destination in 2 1/2 hours.
Check:
60+36(2.5)
=120 mi
Answer:
They are parrellel and share the same angle conguence.
5-(-4)
5 + 4 = 9
exceeds by 9
Answer:
0.2389
Step-by-step explanation:
The amount of warpage in a type of wafer used in the manufacture of integrated circuits has mean 1.3 mm and standard deviation 0.1 mm.
A random sample of 200 wafers is drawn
we are supposed to find What is the probability that the sample mean warpage exceeds 1.305 mm
We will use central limit theorem
According to central limit theorem:
Now we are supposed to find What is the probability that the sample mean warpage exceeds 1.305 mm i.e.P(x>1.305)
Refer the z table
P(z<0.71)=0.7611
Hence the probability that the sample mean warpage exceeds 1.305 mm is 0.2389
