Tisha and her academic team are working to go to state finals. They must have a certain number of points to advance. They have h
kolbaska11 [484]

Answer:

b=\frac{T-a-c-d}{3}

b = (T - a - c - d) / 3

Step-by-step explanation:

Let T be the total number of points required to advance.

a, c and d are points scored in the local matches, and b is the number of points scored in the district match. If b is worth 3 times as much as the other matches, the total number of points is given by:

T=a+c+d+3b

Isolate b in order to find out how many points they need in the district match:

T=a+c+d+3b\\3b=T-a-c-d\\b=\frac{T-a-c-d}{3}

They need to score (T - a - c - d)/3, in the district match in order to win.

irga5000 [103]

Answer:

D. 850 square foot

Step-by-step explanation:

Area of a space is the length

multiply by the width

The area for the kitchen, dining, office and sunroom will be calculated independently and added together.

Note the word "and the office and sunroom are each 10 feet by 10 feet"

Kitchen area = 10 ft x 15ft= 150sqft

Living/Dining area = 20ftx25ft= 500sqft

Sunroom = 10ftx10ft= 100sqft

Office= 10ftx10ft=100sqft

Therefore total surface area is the cumulative of the 4 areas

150sqft+500sqft+100sqft+100sqft= 850sqft

Give an estimate of the mean hardness that you would expect after 37 and 41 hours; and a 85% confidence interval for each estima
Jlenok [28]
The predicted value of hardness at 37 hours is 243.87 and an 85% confidence interval for the mean hardness is (242.12, 245.61). At 41 hours, the predicted hardness is 252 and an 85% confidence interval for mean hardness is (249.83, 254.18). The confidence interval for X is equals to 41 which is wider because the value 41 is farther away from the sample mean X than is 37. As an outcome, the standard error for the prediction is larger.
