Three times the sum of two numbers is 15. One of the numbers is 9 more than one-third of the other number.
a. How can you use a system of equations to find the two numbers?
b. What are the two numbers? Show your work.
Answers
Answer:
8, - 3
Step-by-step explanation:
one number is x, the other is y
x = 1/3y + 9
=> (1/3y + 9 + y) × 3 = 15
=> y + 27 + 3y = 15
=> 4y = 15 - 27
=> 4y = - 12
=> y = - 3
x = 1/3(- 3) + 9 = 8
Miguel drives 200 meters up a hill that makes an angle of 7 degrees with the horizontal ground. To the nearest tenth of a meter, what horizontal distance has he covered? (Only round your answer once)
Answers
Answer:
Step-by-step explanation:
The hypotenuse is 200 meters.
The angle making the ground and the Hypotenuse is 7 degrees.
The trig relationship needed is the cosine.
Cos(7) = x / 200 Multiply both sides by 200
200*cos(7) = x
200* 0.9925 = x
x = 198.51
The calculator held the actual answer of cos(7)

Grandma Gertrude's Chocolates, a family owned business, has an opportunity to supply its product for distribution through a large coffee house chain. However, the coffee house chain has certain specifications regarding cacao content as it wishes to advertise the health benefits (antioxidants) of the chocolate products it sells. In order to determine the mean % cacao in its dark chocolate products, quality inspectors sample 36 pieces. They find a sample mean of 55% with a standard deviation of 4%. The correct value of t* to construct a 90% confidence interval for the true mean % cacao is ________.
Answers
Answer:
t-value = 1.690
Step-by-step explanation:
We are given;
Sample size; n = 36
DF = n - 1
DF = 36 - 1
DF = 35
Confidence level = 90%
However, from the first table I attached, we see that the critical significance level of a 90% Confidence level is 0.05
Thus, in the second table, looking at a DF of 35 and significance level of 0.05, we have a critical t-value = 1.690
