Answer:
$549
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
then, solving our equation
I = 3050 × 0.06 × 3 = 549
I = $ 549.00
The simple interest accumulated
on a principal of $ 3,050.00
at a rate of 6% per year
for 3 years is $ 549.00.
Answer:
I’m pretty sure 549

The order of transformations in a sequence matters; reversing the order will not necessarily give the same image. Is this statement True of False?
Answer:
False
If the transformations include a reflection, then the orientation will change. A translation or rotation will preserve the original orientation

How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given that,
Number of students = 24
Fraction who plays checkers = 2/3
So,
⇒ 2/3 × 24 = 16 students.
Now,
3/8 fraction of students(out of this 16) also play sudoku
So,
3/8 × 16 = 6 students.
Hence "A total of 6 students play sudoku and checkers both".

An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 5.0 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 6 engines and the mean pressure was 5.4 pounds/square inch with a standard deviation of 0.7. A level of significance of 0.025 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
Answer:
Do no reject null hypothesis.
Conclusion:
there is no sufficient statistical evidence at 0.025 level of significance to support the claim.
Step-by-step explanation:
Given that;
mean x" = 5.4
standard deviation σ = 0.7
n = 6
Null hypothesis H₀ : μ = 5.0
Alternative hypothesis H₁ : μ > 5.0
∝ = 0.025
now,
t = ( 5.4 - 5.0) / ( 0.7/√6) = 0.4 / 0.2857 = 1.4
degree of freedom df = n-1 = 6 - 1 = 5
T critical = 2.571
Therefore; t < T critical,
Do no reject null hypothesis.
Conclusion:
there is no sufficient statistical evidence at 0.025 level of significance to support the claim.

Answer:
A) t(x)=948(0.955)^x
Step-by-step explanation:
The key term here is decreases by. This means there's going to be exponential decay. The exponential decay factor, r, in this case, will be r=1-0.045=0.955 and we also know this is exponential decay because r<1. The only possible option that works is A because when x=0 the result should be $948 because only 0 years have passed!

a boat travels upstream for 108 miles in 4 hours, and returns in 3 hours traveling downstream in a river. What is the rate of the boat in still water, and what is the rate in the current?
Answer:
Rate in still water = 27 mph
Rate in the current =36 mph
Step-by-step explanation:
The rate is the speed the boat use to travel in the water
The distance travelled upstream = 108 miles
The time taken to travel upstream = 4 hours
The rate in still water /upstream = 108/4 = 27 mph
The rate in the current /downstream = 108/3 =36 mph

A U.S. Senator from Indiana wanted to know what all her constituents thought about the Clean Air Act that was coming up for a vote in the Senate. She sent a letter to a sample of 257 Indiana voters asking them if they supported the Clean Air Act even if it meant they would have to pay higher prices for gasoline. The results indicated that 39% of the sample supported the Clean Air Act, even if it meant higher gasoline prices. The sample of Indiana voters was intended to represent all Indiana voters; therefore, the value of 39% would be called __________.
Answer:
The value of 39% would be called parameter.
Step-by-step explanation:
When a percentage refers to a sample, it is called a statistic.
When it refers to a population, it is called a parameter.
The sample of Indiana voters was intended to represent all Indiana voters;
This means that the percentage will be used with the following meaning:
"39% of all Indiana voters ..."
That is, referring to the entire population(in this case, all Indiana voters), so would be a parameter.

Answer:
f(-3)= -8
f(2) = 4
Step-by-step explanation:
The first equation x ≤ 0 means that if the variable x, or in our case, -3, is less than or equal to 0, the answer will be calculated into the equation.
3(-3) + 1 = -8
The bottom equation x ≥ 2 means that if the variable, x, or in our case, 2 is more than or equal to 2, the answer is 4. Since 2 is equal to 2, the answer would then be 4.
A deck of cards is shuffled and then divided into two halves of 26 cards each. A card is drawn from one of the halves; it turns out to be an ace. The ace is then placed in the second half-deck. The half is then shuffled, and a card is drawn from it. Compute the probability that this drawn card is an ace. Hint: Condition on whether or not the interchanged card is selected.

Answer:
simple.
Step-by-step explanation:
If you know the angle of a straight line, its 180. first, subtract 180-135. this wqould be 45. therefore, the interior angle is 45. We know that a triangles area always adds to 180, so it would be 45+x+74=180. this would be x=61. to check, add the same thing, 45+74, but instead of x add 61.

Explanation :
(A) We need to find the lowest fuel efficiency in 30's
So we look at the data's in third row
It shows the fuel efficiency of 31,31,36,37 miles per gallon
The lowest fuel efficiency in 30's is 31
(B) Lets write the fuel efficiency from the given table
13, 23, 29, 31,31,36, 37, 43, 44, 45, 46, 51, 53, 53, 58
The lowest fuel efficiency in the overall sample is 13
(C) Lets write the fuel efficiency of 40's
43, 44, 45, 46
So, there are 4 cars in the sample that have fuel efficiencies in 40's
