Bri and Annamarie are picking strawberries at two different strawberry farms that charge a flat fee plus a cost per basket picke

denpristay [2]

The correct answer is a & d.
If you find the equation for Annamarie, you get y = 2.75x+ 11.

Using the slope formula to find what Annamarie pays per basket.
(38.5 - 11)/(10 - 0) = 2.75
Annamarie's flat fee is $11 and Bri's flat fee is $5.50

An analyst wants to include the level of education to a regression model. The level of education has 4 possible values: HS, BS,

ruslelena [56]

Answer:

Three.

Step-by-step explanation:

An analyst wants to include Level of Education in a regression model.

Level of Education has 4 possible values - HS, BS, MS, PHD

How many dummy variables must the analyst add to the regression model, in order to account for the variable LEVEL OF EDUCATION?

Since LOE has 4 possible values, (4 - 1 = 3) dummy variables will be added to the regression model.

If the dummy letter is M for instance, and 1 represents the presence of a particular LOE and 0 represents the absence of that LOE;

M1 = 1 when LOE is HS but =0 when LOE is otherwise

M2 = 1 when LOE is BS but =0 when LOE is otherwise

M3 = 1 when LOE is MS but =0 when LOE is otherwise

So, when M1, M2, M3 are equal to 0, the PHD value is represented.

Diego’s history teacher writes a test for the class with 26 questions. The test is worth 123 points and has two types of questio

maria [59]

Answer:

Number of essay questions are 9.

Step-by-step explanation:

Let the number of multiple choice questions = x and the number of essay questions = y.

As, the total number of question are 26. We get, $x+y=26$

Also, the multiple choice and the essay questions worth 3 and 8 points each.

Since, the total number of points of the test are 123.

So, we have, $3x+8y=123$

So, the system of equations is,

x+y=26 ...........................(1)

3x+8y=123 ............................(2)

Multiply (1) by 3 and subtracting by (2), we get,

5y = 45 i.e. y = 9

So, x+y=26 implies x = 26 - y i.e. x = 26 - 9 i.e x = 17

Thus, the number of multiple choice questions and essay questions are 17 and 9 respectively.

(A) The weight of cans of vegetables is normally distributed with a mean of 1380 grams and a standard deviation of 80 grams. Wha

pychu [463]

Answer:

7.35%

Step-by-step explanation:

μ = 1380

σ = 80

n = 15

P(x>1410)

= (1410-1380)/((80)/(sqrt(15)))

= 1.4524

P(z>1.4524) = 0.4265 (from the graph)

P(z>1.4524) = 0.5 - 0.4265 = 0.0735

The denominator of a certain fraction was 147 greater than its numerator. what was the denominator of this fraction, if after th

Dafna1 [17]

After reducing the fraction it becomes equal to 5/12. Let the common element which was cancelled out be x. So we can say the original fraction was $\frac{5x}{12x}$ .

The denominator of the fraction is 147 greater than the numerator. We can write it as:

12x = 147 + 5x

12x - 5x = 147

7x = 147

x = 21

So, the numerator of the fraction was 5 x 21 = 105
Denominator of the fraction was 12 x 21 = 252

So our original fraction was $\frac{105}{252}$
