Step-by-step explanation:
there is no y intercept but it is 3/4 when you simplify
9514 1404 393
Answer:
11.85 deciliters
Step-by-step explanation:
Your table tells you 1 cup is 0.237 liters. Then 5 cups is ...
(5 cups)(0.237 L/cup) = 1.185 L = 11.85 dL
__
"deci-" is the SI prefix for 1/10. 1.1 liters is 11 tenths of a liter.
Given parameters:
Percentage gain = 300%
Selling cost last year = $2420
Unknown:
Selling cost this year = ?
Solution:
To solve this problem;
Profit percent = 
300 = 
3 = 
S- 2420 = 7260
S = $9680
To make a 300% gain, Jefferson Middle school needs a $9680 from fundraiser sales this year.
Answer:
Step-by-step explanation:
(a)
The sample statistic which is estimated by the population parameter is the sample mean. Moreover it is the best estimate for the population mean.From the information, it is clear that
The sample mean is the best point estimate for the population mean. This clearly indicates that the best point estimate for the population mean is 5.1mg/dl.
(b)
From the information, it is clear that
The degree of freedom is obtained below:
From “Student’s-t Distribution Table”, the required critical value is 2.704 which is lesser than the critical value.
The 99% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment is,

(c)
From the information, it is clear that the cholesterol levels were measured and identified whether the garlic treatment affects the LDL cholesterol levels or not.
It is clear that, the 99% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment is
. By the rejection rule for the confidence interval it is clear that the confidence interval contains 0 which clearly states that the garlic treatments do affect the LDL cholesterol levels.
Answer:
(- 2, 3 )
Step-by-step explanation:
Given the 2 equations
7x - 2y = - 20 → (1)
9x + 4y = - 6 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the term in y
14x - 4y = - 40 → (3)
Add (2) and (3) term by term to eliminate the term in y
23x = - 46 ( divide both sides by 23 )
x = - 2
Substitute x = - 2 into either of the 2 equations and evaluate for y
Substituting into (2)
9(- 2) + 4y = - 6
- 18 + 4y = - 6 ( add 18 to both sides )
4y = 12 ( divide both sides by 4 )
y = 3
Solution is (- 2, 3 )
