How do you compare fractions with the same numerator but different denominator?
Anna007 [38]
To compare fractions with like numerator and different denominators, draw out the numerator and denominators to figure it out. So if you were to figure out 6/10 and 6/17, draw out the denominators and shade in how many of the numerators. Keep in mind to make sure you shade in the same area on the other fraction or else you will get confused.

Ben starts commision as a real estate agent last month his total sales for all the houses he sold $950,000.If ben earns a 3% rat
photoshop1234 [79]

Ben's gross income was $28,500.

Step-by-step explanation:

Sales for the month = $950000

Commission rate = 3%

Amount of commission = 3% of sales for the month

Amount of commission = \frac{3}{100}*950000

Amount of commission = \frac{2850000}{100}

Amount of commission = $28500

Ben's gross income was $28,500.

GalinKa [24]

Answer:

Q1

slope=0.16

intercept=30.2

Q2

78.2

Q3

36%

Step-by-step explanation:

Question 1

We are given that

xbar=280

sx=30

ybar=75

sy=8

r=0.6

The regression line can be written as

y=a+bx

a=intercept

b=slope

where

b=r\frac{sy}{sx}

and

a=ybar-bxbar

b=0.6*(8/30)

b=0.16

a=75-0.16*280

a=30.2

Thus,

slope=0.16

intercept=30.2

Question 2

The regression line in the given scenario

y=30.2+0.16x

Julie pre exam total before the exam was 300.

y=30.2+0.16*300

y=30.2+48=78.2

So, the predicted final exam score of Julie is 78.2.

Question 3

R² denotes the variation in dependent variable y explained by the linear relationship of x and y.

R²=0.6²=0.36

Thus, the proportion of the variation in final exam scores that is explained by the linear relationship between pre-exam scores and final exam scores is 36%.
