sdas [7]

Answer:

confidence interval:

This tells us the degree of certainty or uncertainty that is existent in a sampling method. It gives us a range of values, telling us we are fairly sure that our true value or parameter lies within the range.

Degree of confidence:

This tells us that the confidence interval has captured the true/exact population parameter.

If we have 95% degree of confidence, we are 95% sure that that the exact/true parameter are in the confidence interval

Each course at Mt. Regis College is worth either 3 or 4 credits. The members of the men's swim team are taking a total of 48 cou
kolezko [41]

Answer:

3 Credit Courses = 37

4 Credit Courses = 11

Step-by-step explanation:

1. Set up 2 equations:

3x + 4y = 155

x + y = 48

2. Simplify the second expression for x by subtracting y from both sides

x = 48 - y

3. Substitute 48 - y for x

3(48-y) + 4y = 155

4. Simplify the expression by multiplying by 3

144 - 3y +4y = 155

5. Subtract 144 from both sides and subtract 3y from 4y

y = 11 = 4 Credit Courses

6. Substitute y for equation 2

x = 48-11

7. solve for x

x = 37 = 3 Credit Courses

What is 2x+3y•4 plz help me
Ray Of Light [21]

Use the distributive property to combine like terms. Since we only have one X value and one y value we need to use the 4. 2x times 4 is 4x. 3y times 4 is 6y. Now the equation can be simplified to 4x plus 6y. We have no more like terms so the equation cannot be simplified any further without more context.
