Answer:
Step-by-step explanation:
One pack = Rs 120.5
→ Multiply both the brackets and price by 9
9 packets = Rs 1084.5
Answer:
5/9 is an example of rational number.
Step-by-step explanation:
as the definition of rational number is the number in the form of p/q but the value of denominator q should not be equal to 0. Every integer is a rational number.
Answer:
y=-6/5x-2.6
Step-by-step explanation:
Answer=I
15(x+3)+11x represents the total cost
To solve for this, let's look at the information that we know...
26 students go on the trip
15 students pay $3 more for an additional class (x+3)
26-15=11
11students pay, x, the price of the trip.
So 15(x+3) represents the 15 students who pay for both the trip and the automotive class, and 11x represents the students who simply just pay for the cost of the trip.
Thus, 15(x+3)+11x represents the scenario
Answer: D. A single number calculated from the sample that estimates a target population parameter is called a point estimator.
An interval estimator is a range of numbers that contain the target parameter with a high degree of confidence.
Step-by-step explanation:
When we evaluate an range of values for an unknown population parameter, then it is known as interval estimation .
A single number evaluated from the SAMPLE that estimates an unknown population parameter is known as a point estimator.
The general difference between point and interval estimator is the point estimator is a single value of target parameter while interval estimator is a range of numbers to estimate the values about the unknown population.
