First you do 7.9/ 1/4, that gets you 1.975. that is how much blue paint there is. Then you do 7.9-1.975= 5.925, which is how much white paint she used. So in total she used 1.975 pints of blue paint, and 5.925 pints of white paint.

The cost of Nate's dinner including a 15% tip was $43.70. What was the cost of dinner alone?
Nookie1986 [14]

Answer:

The cost of dinner alone was $37.145

Step-by-step explanation:

15%=0.15----Convert your percentage into a decimal

43.70*0.15=6.555----Multiply the cost of dinner with the decimal

$43.70-$6.555=$37.145----Subtract the last number(6.555) from the total(43.70) to get the cost of dinner alone of $37.145 -This is making you subtract the percentage from the total!

I hope this helped!

A researcher wants to investigate whether there is a relationship between annual company profit ($) and median annual salary pai
ahrayia [7]

Answer:

D. There is not convincing evidence of a relationship between annual company profit and median annual salary paid by the company.

Step-by-step explanation:

In this hypothesis test, the null hypothesis usually states that there is no relationship between the two variables in study.

In opposite, the claim that is being tested is the speculative hypothesis: that there is a significant relationship between both variables.

The researcher takes a sample and the P-value indicates the probability of getting that sample by pure chance <em>if the null hypothesis is true</em>.

Then, a very small P-value, below the significance level, indicates that the sample is very unusual if the null hypothesis is true, what gives evidence to reject the null hypothesis.

In this case, a P-value of 0.56 indicates that the sample is not unusual if the null hypothesis is true, so it gives no support to the claim that the null hypothesis is false and that there exists a relationship between the two variables in study.

A school trip to a museum cost $2,056. A total of 125 chaperones and students went on the trip. Adult admission to the museum co
salantis [7]

Answer:

117 students, 8 adults

Step-by-step explanation:

Let's say a adults went and s students went.

Total cost for adults = 23 for each a = 23a

Total cost for each student = 16s

Number of adults and students = a + s = 125

Total cost = 23a + 16s = 2056

a + s = 125

23a + 16s = 2056

We can solve this by solving for a and then plugging that into the other equation, making it so that there is only one variable

subtract s from both sides in the first equation

a = 125 - s

plug that into the second equation

23(125 - s) + 16s = 2056

2875 - 23s + 16s = 2056

2875 - 7s = 2056

subtract 2875 from both sides to isolate s and its coefficient

-7s = -819

divide both sides by -7 to isolate s

s = 117

a = 125 - s = 125 - 117 = 8
